Enhanced Features

This section describes the new product features of Cisco IOS for S/390 release 2.0.

Improved Performance and Efficiency

• Increased throughput, reduction in CPU utilization, and inbound and outbound multiprocessing.

TCP/IP processing is now multi-threaded instead of single-threaded. This is especially significant to FTP transmissions as it will let you obtain an aggregate transmission rate using up to four FTP applications running at the same time on four different CPUs. Outbound processing occurs in the dispatchable unit of the caller; Inbound processing is done on one or more SRBs to provide multitasking and proper accountability of CPU usage.

• Capability of configuring up to 25,000 tn3270 sessions.

• CLA W performance enhancements. W ith a Cisco 7xxx router and a Channel Interf ace Processor

(CIP), large CLAW blocks can be used. Multiple packets are packed into one CLAW block to increase performance.

Improved Management

With Cisco IOS for S/390 release 2.0 you can dynamically:

• Activate, inactivate, define, and remove virtual IP addresses

• Alter, add, or delete the real IP addresses of interfaces

• Start or stop device drivers

• Start, stop, add, or remove interfaces

• Modify message routing/filtering at component and message suffix levels

• Update message routing—for problem diagnosis situatio ns, message logging levels and

destinations may be manipulated on the fly with operator commands

Enhanced Functionality

•

The ACPEEP trace utility has been replaced by the TRA CE utility that uses the MVS Component Trace facility, IPCS formatting routines, and an interactive TSO / component trace interface (TCPEEP).

• NETSTAT accepts commands from TSO, Telnet, and the operator console.

• SMF records are generated at various processing points such as connection establishment,

connection termination, connection rejection, failed connection attempts, etc. for transport (TCP , UDP, Raw), Server Telnet, FTP, storage utilization, and drivers.

• Logging of tn3270 IP address-to-LU name mapping.

• The STOP command can be used for either a graceful shutdown or for an immediate shutdown.

• Messages can be selectively displayed or suppressed on a component or type basis.

• All Cisco IOS for S/390 address spaces now record trace information onto a common TRACE

address space.

2 Cisco IOS for S/390 Release 2.0 Release Notes

Enhanced APIs

• OS/390 OpenEdition (UNIX System Services) asynchronous I/O (required for DB2 V5 TCP/IP

support) and SRB mode.

• Multiple BIND support for server applications (parallel processing for FTP, Telnet, and vendor

applications).

• Enhanced TLI interface—data spaces, cross memory, SRB mode, etc.

• SAS 6.0 support.

Other Enhancements

• Year 2000 support.

• FTP server support for IP address as RACR OUTE TERMID—allows security rules to deny FTP

access unless permitted by IP address.

• Cisco router-based queuing—IP Type of Service (TOS) can be set for applications to better

interface to Cisco queuing mechanisms like Weighted Fair Queuing (WFQ).

Enhanced APIs

Product Changes

• The parameter WRELIM has been removed from the UDP and TCP statements. Buffering is

handled automatically in Cisco IOS for S/390 release 2.0.

• Some of the control blocks for the POOL command have changed. The EPCB control block is

now called the SEPM, the SRE is now called the SA W, and the ARCB, TUCB, and TSQB control blocks have been combined into the ATCB. The 256B pool no longer exists.

• The message ACC210I Internet Protocol Task Started no longer displays to indicate that

startup has completed. A message will display indicating startup completion in Cisco IOS for S/390 release 2.0. The message number will vary, depending on the device you are using; the message text will be

Media media_name is now operational with one or more active interfaces.

Initialization and termination messages now appear in mixed case. This may impact some automated operations packages that search for messages to invoke some action. You should review these messages and tak e appropriate action.

• Some parameters for Cisco IOS for S/390 release 2.0 have been renamed to improve readability,

but aliases have been added for the names used i n Vers ion releas e 1.0. Th e follo win g names and aliases are available for Cisco IOS for S/390 release 2.0:

4 Cisco IOS for S/390 Release 2.0 Release Notes

Product Changes

As for parameters in the Cisco IOS for S/390 Release 1.0 configuration member APICFG00, the TPCB was replaced with the SPCB. Y ou will only need 3 (default) because there are only 3 API's.

CBUFs were replaced with the set of MBUFs. Previously, there were two CBUFs per session, one for input and one for output. Now all data is buffered in MBUFs, so there is no relation between the size of the CBUF pool, and the sizes of the MBUF pools. Pool sizes are based on the amount of data buffered, not on the number of endpoints.

In Cisco IOS for S/390 Release 2.0, usage of the API is no longer limited, so there was no need for the (1.0) API statement.

• The APP task group may have up to four tasks for parallel processing.

• The SSN parameter of member ACPCFG00 is now in the startup JCL.

• The startup JCL has the following changes:

— WTPLOG11, WTPLOG12, WTPLOG13, and ACLOG DD statements have been replaced

by T01LOG

— T01LOG DD SYSOUT=&SOUT has been added — ACSNAP DD statements have been removed — PRFX=ACS parameter on the EXEC statement has changed to PRFX=T01 — CNFG parameter has been added to the EXEC statement.

• The following pools that were in Cisco IOS for S/390 release 1.0 are not in Cisco IOS for S/390

release 2.0:

— ARCB — CBUF — EPCB — SRE — TPCB — TSQB — TUCB

• The NETSTAT RTM (Reco very and Termination Manager) function is no longer supported.

NETSTAN CONN COUNT and NETSTAT CNFG LNI provide similar information

• The NETSTAT WTOLOG function is no longer supported.

• The LOGSTAMP feature and task is no longer provided. All messages in the T01LOG are

timestamped.

• Updated FTP Server provides compatibility with IBM TCP/IP FTP command

• Support for Inter-User Communications Vehicle (IUCV) sockets

• Support for Channel Data Link Control (CDLC) driver (3745)

• Support for TCPassist to allow TCP CHECKSUM processing to be off-loaded to Cisco

• New Client FTP3 provides compatibility with IBM TCP/IP FTP client input and commands

• New storage parameters are provided to control virtual storage usage for TCP connections

• NETSTAT is available from TSO

• Most PARM members can be dynamically refreshed.

TOPTION OPTCD=QUERY differ between Cisco IOS for S/390 rel ease 1.0 an d Cisco IOS for S/390 release 2.0. The result of the query on release 1.0 returns a value of 1 (allow broadcast), while the result on release 2.0 returns a value of zero (do not allow broadcast).

Returning the value of zero is correct since the default for Cisco IOS for S/390 release 2.0 is do not allow broadcast. Therefore, the SO_BRO ADCAST flag is not set. To set this flag to ON, you must run TOPTION with OPTCD=DECLARE and the TPOIPBRO option set to a value of 1 to override the default. After the flag is set, TOPTION OPTCD=QUERY will return a value of 1.

Cisco IOS for S/390 User's Guide

A correction is required for Chapter 9, “Remote Executor,” of the Cisco IOS for S/390 User's Guide. On page 9-2, in the section “What is the Remote Executor?” the following statement is

incorrect: This product uses version 5.5 of SAS C. You must use SAS/C Release 6.00.

Cisco IOS for S/390 Planning Guide

The information in this section should be added to the Cisco IOS for S/390 Planning Guide.

SERVICE Startup Statement

Keywords IBUF(aaa bbb) and OBUF(aaa bbb) have been added to the SERVICE startup statement to allow default override:

IBUF(aaa bbb) If the service name is TELNET, you can use IBUF to specify the number of

input buffers as aaa, and their size as bbb. The lower limits are (2 256); defaults are (1 1460).

OBUF(aaa bbb) If the service name is TELNET, you can use OBUF to specify the number of

output buffers as aaa, and their size as bbb. The lower limits are (2 256); the defaults are (4 1460).

The minimum value for IBUF and OBUF is 512; it is the product of multiplying the buffer size times the number of buffers. The buf fer size cannot be less than 256, and the number of buffers cannot be 0, so the lower limit would be (2 256) or (1 512).

Enhancements to the Global Exit Facility

The following enhancements have been made to the Global Exit Facility.

10 Cisco IOS for S/390 Release 2. 0 R el e ase Notes

Cisco IOS for S/390 Planning Guide

Exit Work Area

If requested, the exit facility provides a work area to the exit program upon each invocation, except the INIT exit point. Request the work area with the EWALENGTH parameter of the EXIT statement in member IJTCFG

xx, or with a parameter returned by the program at the INIT exit point (the

program parameter taking precedence). The Exit Work Area (EWA) addressed will be passed to the exit program at each exit point as the

fifth parameter, following the address of the message-writing routine.

Note The parameter lists for all exit points must be updated.

The EWA size can be from 1 to 65532 bytes. It is taken from pooled storage; the smallest pool that will satisfy the requested size will be used. Pool usage can be monitored via the IFS POOL command. One of the following pools will be used:

Table 3 EWA Pools Pool Name EWA Size

256B 1-252 512B 253-508 01KB 509-1020 04KB 1021-4092 08KB 4093-8188 16KB 8189-65532

Note These figures are provided to allow the exit program designer to make efficient use of the

EWA buffers. It is important that the exit use only the size requested on the EWALENGTH parameter, or by the INIT exit. The exit facility monitors the exit program's use of the EWA, and will force an ABEND if an overrun is detected, even if space remains in the buffer.

Add the following parameters to the INIT exit parameter list, following the subsystem ID address:

Table 4 INIT Exit Parameters

address of a recovery routine to be called in the event the exit program ABENDs at a subsequent entry point.

Cisco IOS for S/390 Release 2.0 Release Notes 11

Documentation

Exit Recovery Routine

The exit program can supply the address of a recov ery routine via a parameter returned at the INIT exit point. The exit facility calls this routine in the event of an ABEND in the exit program. The recovery routine is called in the same mode as the ABENDing exit program, and is passed the System Diagnostic Work Area (SDWA) address and the EWA address (if any). Since the exit's recovery routine is called after the system's Recov ery and T ermination Manager (R TM) has finished processing the ABEND, it should perform only local clean-up functions. Any updates to the SDWA are ignored. The recovery routine should not attempt to free the SDWA, since this will be done by the exit facility.

Recovery Exit

Exit Point: When an ABEND has occurred in an exit program. Function: Perform clean-up associated with the exit program. Dispatchable Unit: Identical with the ABENDing exit program. Register contents are shown in the following table.

T able 5 Recovery Exit Register Contents Register Contents on Entry

R00 SDWA (if processing under an SRB, a copy of the SDWA) R01 Exit Work Area address (if applicable) R02-R12 Zeros R13 Save area address R14 Return address R15 Entry point address

On return from the recovery exit, R13 must be restored.

Exit Parameter List Mapping Macro - T00DEXPL

A new macro, T00DEXPL, is supplied to map the parameter lists to the exit program at the various exit points. The macro is distributed in the SAMP library.

Refreshing USSTAB

USSTAB tables can be refreshed with the REFRESH command. In the “APP Commands” section, which describes the REFRESH command, the second sentence

of the description of the REFRESH command, the USS Table should be added. That sentence should be corrected to read as follows:

“It can be used to refresh the LU pool, greeting member, or the USS Table used by Server Telnet.” The correct syntax is:

[ APP ] REFRESH TASK ( n ) [ LUPARM ( mem_name ) | GREETING ( mem_name ) |

USSTAB ( tbl_name ) ]

Syntax Description

USSTAB (tbl_name) Specifies the USS Table tbl_name coded in the active APPCFGxx SERVICE

segment to be refreshed.

Note LUPARM, GREETING, and USST AB are mutually exclusive.

The following is an example of the usage of the REFRESH USSTAB command.

REFRESH USSTAB( T01USS01 ) TASK( 1 )

Cisco IOS for S/390 Release 2.0 Release Notes 13

Documentation

The REFRESH command is described in the “Cisco IOS for S/390 Operation” chapter.

Parameters for the SVCDUMP Command

Two parameters have been added to the SVCDUMP command, ASID and J OBname. These parameters let the user request that other address spaces be dumped along with Cisco IOS for S/390.

ASID(asid_list) A list of address space IDs. Cisco IOS for S/390 will include these

JOBname(jobname_list) A list of one-to-eight character jobnames. Cisco IOS for S/390 will

address spaces in the dump. This parameter can be combined with the JOBname parameter for a total of five address spaces.

The address space IDs may be listed in decimal or in hexadecimal notation, as x’999’.

include these address spaces in the dump. This parameter can be combined with the ASID parameter for a total of five address spaces.

Note: If there is more than one job active in the system with the same jobname Cisco IOS for S/390 will dump the first one found in the Address Space Vector Table.

The SVCDUMP command is described in the “Cisco IOS for S/390 Operation” chapter.

Protocol Layer Events (Subtypes 110 - 123) Descriptions

The SMF subtype 110-123 records, described on page 3-17, are written to record certain protocol-related events, such as a bind or connect request.

The following table describes the relationship of each of these subtypes:

Subtype Description

110 Endpoint create 111 TCP connect request 112 TCP accept request 113 TCP connection close 114 TCP bind 115 TCP unbind 116 TCP listen 117 UDP bind 118 UDP connect 119 UDP close 120 RAW open 121 RAW close 122 Endpoint destroy 123 Inbound connection failures

MU1IUCV USERMOD Correction

The zap example for EZASOK03 configuration overrides and defaults on page 4-14 and the USERMOD on page 4-15 are incorrect. Use USERMOD MU1IUCV in the SAMP data set instead.

14 Cisco IOS for S/390 Release 2. 0 R el e ase Notes

NETSTAT RTM Command

The NETSTAT diag nostic commands are described beginning on page 5-12. The NETSTAT RTM command can be used by a Telnet user to display a continuous activity report on all active hardw are interfaces. The frequency is determined by the value in seconds, and defaults to 9 if not entered. Permissible values are between 1 and 32767.

Once activated, the R TM command will continu e to display a time-stamped connection counter , and LNI counts and rates. The display itself will appear after the specified interval in seconds, but the rate is based on a time difference between now and the last sampling. If multiple RTM commands are in effect, the rates will not always be consistently smooth.

To terminate the RTM command, press Enter.

Capture of User Data in a TLI Trace

You can use the trace facility or TCPEEP to capture user data in a TLI trace. The data is from the TPL field DABUF.

To capture and view user data, two actions are required.

• The filter MAXTLIDATA (alias MTLIDATA or MTDATA) must specify the maximum amount

of data to be captured. The default is zero; the maximum is 65,535.

Cisco IOS for S/390 Customization Guide

For example, the following command will capture up to 100 bytes of data:

GROUPS( ( TLI,'MTDATA( 100 ) ' ) )

• The FORMAT param eter must be specified for the maximum amount of data to be displayed.

You may also specify which translation to use:

— TLIDATA(nn) - mixed translation (default) — TLIEBCDIC(nn) - EBCDIC translation — TLIASCII(nn) - ASCII translation

For example, the following command will display up to 50 bytes of captured data:

FORMAT( TLIEBCDIC( 50 ) )

The TCPEEP command is described in the “Diagnostic Commands” chapter.

The default maximum data captured by the TCPEEP option NETIF is now 256 bytes of data, which includes device header, IP header, etc. A new filter option, MAXDATA (alias MDATA), allows resetting this to a maximum of 65,535.

This is an example of the usage of the MAXDATA (MDATA) filter option:

GROUPS( (NETIF,'MDATA( 512 ) ' ) )

This command will capture up to 512 bytes of data. The FORMAT options DATA(nn), EBCDIC(nn), and ASCII(nn) still limit what is seen.

TCP MINDEV and RTO Defaults Changed

Two of the defaults in the TCPCFG00 file have changed. For the TCP statement, the MINDEV parameter defaults to 40 (0.10 second). Also on the TCP statement, the RTO parameter defaults to 0; range 0 - 6000.

APPEND Keyword for LUPOOL Statement

In configuration member APPLUP00, a new keyword, APPEND has been added to the LUPOOL statement.

LUPOOL NAME(pool_name)

APPEND(lu_name,...,lu_name)

Syntax Description

APPEND Specifies additional LU names for an LUPOOL. When APPEND is specified with

a previously defined NAME, the LU names specified are appended to that previously defined for LUPOOL. There is no limit to the number of LUPOOL statements that can be specified with the APPEND keyword. Duplicate LU name checking is done for the complete list of LU names (original and appended).

Example:

LUPOOL NAME(VLTPOOL0) LU(T20000,T20001,T20002,T20003,T20004,T20005,T20006,T20007,T20008) LUPOOL NAME(VLTPOOL0) APPEND LU(T20010,>T20011,T20012,T20013,T20014,T20015,T20016,T20017,T20018)

CDLC Considerations

The 3746-900 unit is configured with a network MTU size, but will override it with the lowest MTU size it encounters. That MTU size will be applied to whatever mainframe software will be running next. Therefore, if a small MTU size is used, that will become the restriction for subsequent IP packet sizes and may cause problems if fragmentation is not allowed. The CDLC MTU size should correspond to its network configuration parameter.

Recommendations on Setting TOS

The following recommendations for setting TOS (type of service) have been added to the Cisco IOS for S/390 Customization Guide.

When setting TOS, precedence bits should be set to zero.Of the next 4 bits, only one is to be set on in any one packet: 16 = mindelay, 8 = max thruput, 4 = reliability, 2 = min cost. These should be set as follows:

• Telnet = 16

• FTP Control = 16, Data = 8,

• SMTP Commands = 16, Data = 8

• DNS query = 16, zone transfer = 8

• SNMP = 4

• NNTP = 2

16 Cisco IOS for S/390 Release 2. 0 R el e ase Notes

Note that Cisco IOS for S/390 does not configure TOS for SNMP or DNR queries, and NNTP is not implemented. Telnet and the FTP control connection can be configured in the Service statement. The FTP data connection can be configured in the FTP statement. The SMTP connection can be configured on the Service statement.

LOGGING Keywords Logically Grouped

The LOGGING command has been changed slightly to introduce a logical grouping of the keywords that control SYSOUT attributes and when the log is spun. The changes in this section apply to the Cisco IOS for S/390 System Management Guide.

This change makes the command easier to use in that you do not need to specify all of the keywords for an action, as is shown in the following table.

Keywords specified Action

All the keywords are specified. The LOGGING command will change all of the attributes as

Some of the keywords are specified. The specified attrib utes are changed, b ut the remaining att ributes

None of the keywords are specified. None of the attributes of the group will be changed, and any

Cisco IOS for S/390 Customization Guide

specified.

of the grouped attributes are set to the default.

previous attributes will be carried forward.

The SYSOUT attributes that are grouped are:

• CLASS

• DEST

• FORM

• WRITER

The SPIN attributes that are grouped are:

• LINES

• MINUTES

• SYNC

Note The NOW keyword is not associated with LINES, MINUTES, and SYNC. The PRINT and

WTO keywords are separate from each other, and from all the rest.

LOGGING Examples

Here are some examples of the usage of these grouped keywords.

LOGGING PRINT(ALL)

Prints all messages; leaves WTO, SYSOUT, and spin unchanged.

LOGGING WTO(ALL)

WTOs all messages; leaves PRINT, SYSOUT, and spin unchanged.

LOGGING CLASS(X)

Resets SYSOUT class to X; defaults DEST , FORM, and WRITER, and leaves remaining keywords unchanged.

Cisco IOS for S/390 Release 2.0 Release Notes 17

Documentation

LOGGING SPIN NOW

Spins the log now; leaves all specifications unchanged.

LOGGING SPIN(LINES(5000) MINUTES(60))

Resets spin to every 5000 lines or 60 minutes, whichever comes first; leaves remaining keywords unchanged.

LOGGING PRINT(ALL) WTO(ALL) WRITER(TOLSTOY) SPIN(SYNC) NOW

Prints and WTOs all message, resets SYSOUT writer to TOLSTOY and defaults CLASS, DEST , and FORM. Also resets spin to every hour on the hour, ignoring line count, and spins the log now.

Cisco IOS for S/390 Prefixed Messages

Installation Requirements

Cisco IOS for S/390 Version release 2.0 is composed of the base Cisco IOS for S/390 release 2.0 distribution tape and a tape containing additional PTFs. You must install both tapes.

Installing Cisco IOS for S/390 Release 2.0

MVS Releases

Cisco IOS for S/390 release 2.0 requires MVS/ESA Release 5.1 or higher . MVS/SP releases are not supported. OpenEdition support is available only at MVS/ESA Releases 5.x and above.

The MVS PTF associated with APAR OW30322 must be applied prior to starting Cisco IOS for S/390 release release 2.0.

APF Authorizations

The PFSLOAD library is used with OpenEdition and contains Physical File System (PFS) modules. It must be APF-authorized to work correctly.

If you use the SASLINK data set as described in the ALLOCT00 section of these instructions you must also APF-authorize that library.

Link List Data Sets

TCPLOAD must never be in the link list. If SASLINK is used, you must place it after the LINK library in any concatenation to ensure that the Cisco IOS for S/390 version of LSCNCOM is used.

Automated Operations Impact

COPY INDD=((INDD,R)),OUTDD=OUTDD

26 Cisco IOS for S/390 Release 2. 0 R el e ase Notes

Note Some members of the CNTL library are now under SMP/E control and some members will

be loaded as part of the APPLY process. When modifying the ALLOCT00 JCL stream, verify that the TCPJCL DDDEF points to your CNTL library. Also, you should exit the CNTL library as soon as the INSTSMPE job stream is submitted. Keeping the data set open in your TSO session will cause the APPLY job to fail.

Allocate the Data Set Names for Cisco IOS for S/390 release 2.0

References to member names in the following instructions are located in the control file that you loaded onto your system in Control File JCL.

1 TCPNAMES

Member TCPNAMES in the CNTL library is used to customize all other installation members. The TCPNAMES member, a REXX EXEC, lets you assign consistent data set name allocations.

You can customize member TCPNAMES so that you do not need to edit the other installation members manually.

Step 1 Edit the data set name symbolics to be consistent with naming conventions of your site.

Verify adequate space on the volume specified.

Installation Process

The LNKINDX data set is allocated as a SYS1 data set in job ALLOCT00. You can change to a different high level node if you do not have authority to allocate SYS1.

Step 2 Copy the TCPNAMES member to a CMDLIB listed in the SYSPROC concatenation of

your TSO logon procedure as described below. Determine the name of your logon procedure. It is identified on the first screen of your

TSO logon. Determine the data set in which your logon procedure is located. It is most likely in

SYS1.PROCLIB. If not, from your TSO command line execute the command TSO LISTA, which will list all data sets allocated to your TSO session. Your TSO logon procedure is most likely located in a data set with final node of PROCLIB.

Determine the CMDLIB you will use. Select the member containing your logon procedure, find the SYSPROC DD, and select a CMDLIB to copy TCPNAMES into.

If you are copying TCPNAMES into a VBA library , you must delete the line numbers that appear in columns 73 through 80 after you copy it in.

2 JOBCARD

Member JOBCARD in the CNTL library is used by the TCPNAMES EXEC to customize the jobcards of all other installation members.

Choose a jobcard and copy it into the CNTL data set member JOBCARD. If you are using JES3, replace the JOBPARM card with the following:

//*MAIN LINES=(999,W)

3 ALLOCSMP

Member ALLOCSMP allocates the data sets that contain your consolidated software inventory . Edit and submit member ALLOCSMP according to the instructions below .

Before submitting the ALLOCSMP member, consider the following: — ALLOCSMP requires 53 cylinders.

Cisco IOS for S/390 Release 2.0 Release Notes 27

Installing Cisco IOS for S/390 Release 2.0

— Verify that the Linkage Editor/Binder attributes for the CSI include NCAL, LET, and

SIZE=(660000,160000). If you are using the linkage editor you must remove the NCAL, LET, and SIZE parameters from the ALLOCSMP JCL. You must also change your maximum return code to a 4.

— For users running MVS/ESA 4.3 or above, Binder is now supported. To use the Linkage

Editor, update the options entry for IEWL to point to HEWLF064. In Cisco IOS for S/390 release 2.0 the default is to use HEWLH096, which invokes the Binder.

— Cisco IOS for S/390 release 2.0 must be installed into a new CSI; you cannot use a shared

CSI. Data set allocation changes in this release will cause attempts to install over an existing release to fail.

Edit the ALLOCSMP member by entering TCPNAMES at the command line. Submit ALLOCSMP.

4 ALLOCT00

Member ALLOCT00 in the CNTL library allocates the libraries that will contain the Cisco IOS for S/390 base product.

Before submitting the ALLOCT00 member, consider the following:

ALLOCT00 requires 2333 tracks. Y ou may choose to distribute some of the libraries across multiple volumes. This requires manual editing of ALLOCT00 after you execute TCPNAMES.

The PFSLOAD and FTPLOAD libraries are allocated. The PFSLOAD library is used with OpenEdition and contains Physical File System (PFS) modules. It must be APF-authorized. If you are not using OpenEdition, the library is not requ ired. The FTPLOAD library will contain the FTP3 load module for IBM-FTP client compatibility.

Edit the ALLOCT00 member by entering TCPNAMES at the command line. Submit ALLOCT00.

5 INSTSMPE

Member INSTSMPE in the CNTL library is used to install the base product. Before submitting the INSTSMPE member, consider the following:

The Cisco IOS for S/390 release 2.0 product consists of four FMIDs. You must apply the Cisco IOS for S/390 FMID, T01T520, and the translate table FMID, T01X520. Optional FMIDs are the development FMID, T01D520, and the SAS 6.0 runtime FMID, SAS0600. No user changes are required.

You may submit only the RECEIVE portion of this job first. This will let you review the HOLDDATA, especially any hold action that may appear, and take appropriate action. It will also let you add additional BYPASS HOLD keywords to your APPLY statement.

Edit the INSTSMPE member by entering TCPNAMES at the command line.

If you are using a tape management system such as CA1, you must modify the label parameter on your DD statements to include EXPDT=98000.

LABEL=1,NL,,EXPDT=98000

If you are using JES3, replace the JOBPARM card with the following:

//*MAIN LINES=(999,W)

Submit INSTSMPE.

28 Cisco IOS for S/390 Release 2. 0 R el e ase Notes

Installation Process

Note Exit the CNTL library as soon as the INSTSMPE job stream is submitted. Keeping the data

set open in your TSO session will cause the APPLY job to fail.

6 HOLDDATA

Before installing system maintenance, obtain the most recent HOLDDATA file. You can obtain this file through anonymous FTP by logging in to ftp.interlink.com and requesting it as shown in the following example. For user ID, use anonymous; for password, user your email address.

ftp2 open ftp.interlink.com cd pub/ptf520 ascii get hold.txt

At the prompt for a storfile name, enter the following (including the single quotation marks):

'your_80byte_pds(member)' quit

This file is in ASCII and is to be downloaded to MVS for processing by SMP/E. Translation of ASCII text to EBCDIC is automatic during transfer.

PTFs may have a HOLD status associated with them that should be reviewed before you begin the APPLY process. Review the ++HOLD requirements after you RECEIVE the SYSMODS. When satisfied, use a BYPASS(HOLDSYS) on the APPLY command and rerun the APPLY job without the CHECK parameter.

Use this HOLDDATA file as your SMPHOLD file in the SMPHOLD DD statement. If you do not have Internet access, contact Cisco TAC for the latest HOLDDATA file.

7 SMPECUMT

Member SMPECUMT in the CNTL library is used to apply maintenance to the base product. The non-labeled (VOL=SER=PTFTAP) maintenance tape distributed with the product contains

the latest maintenance for the Cisco IOS for S/390 product. Apply this maintenance, as well as any maintenance obtained interactively from our web site, prior to beginning any customization, as configuration files or parameters may have changed.

Before submitting the INSTSMPE member, consider the following: — You may submit only the RECEIVE portion of this job first. This will let you review the

HOLDDATA, especially an y hold action that may appear and take appropriate action. It will also let you add additional BYPASS HOLD keywords to your APPLY statement.

Edit the SMPECUMT member by entering TCPNAMES at the command line. — If you are using a tape management system such as CA1, you must modify the label

parameter on your DD statements to include EXPDT=98000.

LABEL=1,NL,,EXPDT=98000

— If you are using JES2, add the following statement:

/*JOBPARM L=9999

Cisco IOS for S/390 Release 2.0 Release Notes 29

Installing Cisco IOS for S/390 Release 2.0

— If you are using JES3, add the following statement:

//*MAIN LINES=(999,W)

— Verify that the tape unit is correct. It is hardcoded as CART. Submit SMPECUMT. SMPECUMT will generate the following message:

GIM34701E: SMPE expected to find ++MCS

This is expected and normal. View the SDSF job output log to verify accuracy of the job. Execute the ISPF Browse or SDSF

View command F ‘APPLY PROCESSING WAS SUCCESS’ ALL. Confirm that the number of occurrences matches the number of PTFs you applied.

8 Web Site PTFs

If you require additional PTFs that are not on the CUM tape received with your installation package, access the following web site for a list of PTF numbers available:

http://www.interlink.com/support/

Scroll down approximately two pages and select the hypertext /pub directory. Select the ptf520 directory.

Note Sometimes the incorrect year appears in the PTF creation dates. This is a known b ug with

the Microsoft Internet Explorer and has no effect on the validity of the PTFs. When using Microsoft Internet Explorer to access a PTF directory, the year in the date adjacent to a file is displayed as the current year if the file has not been updated for six months, even though the file might have been created in the previous year.

Create a data set to contain the PTFs you will select. we recommend you use the same naming convention you used in the TCPNAMES High Level Qualifiers (HLQ) for your LNKINDX variable.

When you know the PTF numbers you want from the web site, set up a batch job with multiple GET commands using the specific PTF numbers and FTP to the Interlink anonymous FTP site. For User ID, use anonymous; for password, use guest.

open ftp.interlink.com anonymous guest bin cd /pub/ptf520 get TPnnnnn.BIN ‘your_data_set_name( TPnnnnn ) ’ bye

Customization

This section describes the members that can be customized.

30 Cisco IOS for S/390 Release 2. 0 R el e ase Notes

Installation Process

PARM Customization

The statements described in this section are all described in the Cisco IOS for S/390 Customization Guide. That document is the definiti ve source of information for these members. These members are

all shipped with the product.

Note P ARM members are now under SMP/E control. In order to avoid possible overwrite by future

PTFs, copy your 00 members to 01 or another suffix of your choice. You must also make the appropriate adjustments in members STARTxx, DNRCFGxx, and TCPCFGxx which point to other PARM members.

Some of the Cisco IOS for S/390 release 1.0 members have been changed or deleted and many parameters have been relocated to different members in Cisco IOS for S/390 release 2.0. We recommend that you select your Cisco IOS for S/390 release 2.0 members and then split screen to browse your Cisco IOS for S/390 release 1.0 members in order to transfer the appropriate parameters to the correct Cisco IOS for S/390 release 2.0 members. Use the chart at the beginning of this document to see where parameters were in Cisco IOS for S/390 release 1.0.

APPCFGxx: Verify that the service statements that were in member ACPCFGxx in Cisco IOS for S/390 release 1.0 are now in APPCFGxx.

APPLUPxx: The LUPOOL statement has a new ALLOCATE parameter: ALLOCATE( FIRST ) Directs LUPOOL to allocate the first available LU.

Due to performance considerations this is the preferred startup option This is the default.

ALLOCATE( NEXT ) Directs LUPOOL to allocate LUs in sequential order.

This option adds flexibility in an error LU situation. This option should be specified at a site only at the direction of TAC personnel when the VTAM network is not working properly.

DNRxxxxx: In general, you can transfer or copy these members from the Cisco IOS for S/390 release

1.0 PARM library to the Cisco IOS for S/390 release 2.0 PARM library. However , be sure to verify accuracy and validity of the parameters and their placement.

DNRALCxx: Users running in a multihomed environment must place entries in the DNRALCxx member for all non-loopback LNIs to allow domain name resolution to occur. If only one is defined, expect the following message:

T01CF150E APP configuration error: invalid SUBSYS Name subsysname

Processing continues after the message displays. DNRCFG01: Replace NAMESERVER(NO NE) with NAMESERVER(DNRNSC01). You will be

customizing this member later.

DNRNSC01: Complete the lines requesting that you “set serv er for your domain.” IJTCFGxx: The existing Cisco IOS for S/390 release 1.0 authorization keys work for Cisco IOS for

S/390 release 2.0 if you use the same CPU. CPU serial numbers, processor status, and other information can be obtained via execution of the MVS command D M=CPU.

STARTxx: To aid in diagnosis, insert the following statement on the first line of the STARTxx member:

MODIFY TRACE ON SIZE(256)

Cisco IOS for S/390 Release 2.0 Release Notes 31

Installing Cisco IOS for S/390 Release 2.0

TCPCFG01: There is a new NETMASK parameter that lets the Network Information Center (NIC) divide the Class B addresses into Class C addresses to alleviate some of the worldwide IP address shortages. If your installation is affected you will have already applied to the NIC for these addresses.

USERMOD Customization

The statements described in this section are all described in the Cisco IOS for S/390 Customization Guide. These members all ship with the product.

UMODTRAN: Read the section “Maintaining Translation Tables Using UMODTRAN” in the “T elnet and tn3270 Configuration Chapter” of the Cisco IOS for S/390 Customization Guide.

UMODAPPL: This is the usermode that you will most likely apply. In order for UMODAPPL to run, you must modify member APPLNAME in the SAMP library with your correct VTAM APPL.

UMODPOOL: UMODPOOL uses member ACCPOOL in the SAMP library. Old style 3174 controllers did not let things start with 01, so the starting name is ACSVLT02.

Invoking Cisco IOS for S/390 Release 2.0

The startup member, RUNTCP, is located in the control library you designated in your installat ion JCL. This member will invoke Cisco IOS for S/390 release 2.0. You will have a choice to submit RUNTCP as either a started task or as a batch job.

Before submitting the RUNTCP member, consider the following:

• The CMND data set is no longer allocated or used. The ST ART00 member is now located in the

PARM data set. The RUNTCP member in the CNTL data set reflects this change.

• Two libraries, PFSLOAD and FTPLOAD, are allocated. The PFSLOAD library is used with

OpenEdition and contains Physical File System (PFS) modules. It must be APF-authorized to work as specified in the Installation Requirements section earlier in this document. If you are not using OpenEdition, the library is not required. The FTPLOAD library is reserved for future use.

Note TCPLOAD must never be in the linklist. If SASLINK is used, you must place it after the

LINK library in any concatenation to ensure that the Cisco IOS for S/390 version of LSCNCOM is used.

Edit the RUNTCP member.

• Do not execute TCPNAMES.

• Change the symbolic ‘TRGINDX’ to the value you specified in member TCPNAMES.

• V erify that the symbolic SSN=A CSS is available for use. The MVS command DSSI will display

subsystem names that have been invoked during the life of the current IPL. You can use ACSS if it either does not display or if it shows as inactive. If ACSS is acti ve, you must choose a dif ferent name for your subsystem.

• Verify that th e symbo lic ‘S RC=% ’ is available for use.

• If you are using a user VTAMLIB, you must add it to your STEPLIB concatenation to make sure

RUNTCP can find your USSTAB.

• You need to add one of the following lines immediately after the JOBCARD to support

diagnostics.

32 Cisco IOS for S/390 Release 2. 0 R el e ase Notes

Diagnosis and Problem Reporting

— If you are using JES2 add:

/*JOBPARM LINES=9999

— If you are using JES3, add:

//*MAIN LINES=(999,W)

• To prepare RUNTCP as a batch job:

— Complete your RUNTCP J OBCARD and add the following JCL statements to the end of the

RUNTCP JCL stream:

// PEND //label EXEC TCPIP

To prepare RUNTCP as a started task:

— Delete the RUNTCP JOBCARD and comments that appear prior to the PROC statement. — Copy member RUNTCP into a system PROCLIB.

Submit RUNTCP.

• To submit RUNTCP as a batch job, submit member RUNTCP.

• To submit RUNTCP as a started task, issue the MVS command S RUNTCP.

• The message ACC210I Internet Protocol Task Started no longer displays to indicate that

Media media_name is now operational with one or more active interfaces.

To stop RUNTCP, issue the MVS command F RUNTCP,P CLEAR and answer YES to the reply. This reply is generated if you have the PROMPT parameter specified in your IJTCFGxx member.

If RUNIUCV is to be stopped, it must be done after RUNTCP has terminated.

Diagnosis and Problem Reporting

Generally, Cisco needs the following documentation to help diagnose pro blem s thoroughly:

• TCP SNAP

• TCPEEP

• SVC dump of the Cisco IOS for S/390 and other related address spaces

• JCL output of the Cisco IOS for S/390 job

Obtaining GTF Output

The “Command Scripts” section of Chapter 2, “Cisco IOS for S/390 Operation” in the Cisco IOS for S/390 System Management Guide provides a sample command script to start GTF and turn on

tracing.

Obtaining a SNAP Dump

As soon as a problem occurs, enter the following MVS command to your Cisco IOS for S/390 address space:

Cisco IOS for S/390 Release 2.0 Release Notes 33

SAS/C Usage Notes

F RUNTCP,TCP SNAP ALL

Obtaining a TCPEEP

Read the Cisco IOS for S/390 System Manag e m e nt for information to help you set up and submit your trace address space and submit the TCPEEP TSO command.

Obtaining an SVC Dump

Read the IBM document MVS/ESA System Commands Reference Summary for the syntax of the required DUMP commands. In particular, include all jobs involved in the problem using the JOBNAME parameter of the DUMP command.

Obtaining JCL Output

Copy the JCL output of RUNTCP to a file using the following procedure:

• If you are using JES2/SDSF, type XDC beside the job listed in SDSF and follow the panel

instructions. This will let you copy to a data set of your choice. Generally, for every thousand lines of job output you need three 3390 tracks.

• If you are using JES3, you may use FLASHER or a similar product to copy the RUNTCP output

to a data set in a similar fashion.

SAS/C Usage Notes

You must use the SAS 6.0 compiler, header f iles, object files, and runtime libraries to COMPILE and LINK using the Cisco IOS for S/390 release 2.0 socket library

You can run a down-level (SAS 5.5) c program against Cisco IOS for S/390 release 2.0, and it can be compiled and linked using the Cisco IOS for S/390 release 1.0 (or lower) socket library . Howe ver , it must be run using the SAS 5.5 runtime library. This program can then run over the Cisco IOS for S/390 release 2.0 stack.

• Mixing any SAS 6.0 modules/headers with SAS 5.5 modules/headers will cause problems.

• Mixing any Cisco IOS for S/390 release 2.0 socket modules/headers with Cisco IOS for S/390

release 1.0 socket modules/headers will cause problems.

• Mixing runtime modules between releases will cause problems.

In addition, in SAS 6.0, LSCNCOM is always dynamically loaded. If linked with the application program in 6.0, LSCNCOM will cause ABENDs.

Converting from Cisco IOS for S/390 Release 1.0 to Cisco IOS for S/390 Release 2.0

LOGGING Statement

One of the design goals of Cisco IOS for S/390 release 2.0 was to reduce the volume of message output printed. SMF recording was enhanced to allow many of the events previously recorded only by a message to be written to the SMF datasets.

Messages were renumbered so that each message now has a unique prefix, which includes both a severity, and a component code to identify the area of the product which issued the message. The LOGGING statement was added in IJTCFGxx to give you control over which messages will be written to the log or to the console. Message routing can be controlled by severity and component, using the LOGGING statement.

By default, many events previously reported by messages will go unreported in Cisco IOS for S/390 release 2.0. Some customers may prefer to continue seeing the same level of message output as in previous releases of the product. The following LOGGING statement parameters are designed to give a lev el of e v ent recording reasonably close to what was provided b y pre vious releases of Cisco IOS for S/390:

LOGGING PRINT(ALL,(DN,RFEW),(IF,RFEWIS))

You may find that there are other defaults you will wish to change. The LOGGING parameters can be changed dynamically by means of the new LOGGING command, making it easy to experiment with different configurations.

For complete information on the LOGGING statement, and the LOGGING operator command, refer to the Cisco IOS for S/390 documentation.
