Java specific Configuration with SAP NetWeaver 2004(s)
and KMC
Configuration via the Visual Administrator
Please, proceed the following steps:
• Define the scanner group
• Define the Virus Scan Provider
• Define the Virus Scan Profile
3
Define the Scanner Group
A scanner group combines multiple virus scanners of the same type. You need the
Groups in order to specify virus scan profiles later. SAP does not supply any scanner
groups.
In the Visual Administrator, choose the cluster Virus Scan Provider.
If the service is not started, click the Start button (or right-click on Virus Scan
Providers and select Start)
4
Create a scanner group by pressing the New button on the tab Groups.
Specify the name of the new group (AVIRA) in the dialog box and confirm your entry
with OK.
The group names are case sensitive. You have to use the same names later in the
KMC.
5
Select the node for the newly created group.
- Activate the Default option on the Settings tab to set the group as default.
- Enter a description of the group in the Description field.
- To save you entries, press Set.
You do not have to make any configuration on the Parameters tab at this point.
6
Define a Virus Scan Provider
- Choose the cluster Virus Scan Provider in the Visual Administrator.
On the Provider tab page, select the Virus Scan Adapter node and press the New
button, to create a new virus scan adapter.
Specify the name of the new provider (AVIRA) in the dialog box and confirm your
entry with OK. The entered name is automatically saved with the prefex “VSA_”.
The names are case sensitive. You have to use the same names later in the KMC.
7
Select the node for the newly created provider.
On the Settings tab, activate the Default option, to set the provider as default.
Default: This adapter is selected if no other VSA is specified.
Name: Name of the virus scan adapter. The name entered is automatically saved
with the prefix “VSA_”.
Description: Description of the current adapter.
Group: The drop down list shows the available groups to which you can assign the
current adapter.
Init. Interval: The time interval (in hours) for the NetWeaver to end VSA and restart
it.
Values:
0 restart only when the Virus Scan Service ends/starts, or when the Virus Scan
Provider is deactivated/activated.
1 for test environments. Advantage: the configuration is read hourly, without having
to end the servlet engine.
8
Max Instances: The maximum scan instances allowed to the VSA by NetWeaver.
Default: 10.
In order to save you entries in the Settings tab, select Set.
You do not have to make any configuration on the Parameters and Trace tab at this
point.
In order to activate the Virus Scan Provider, mark it and choose Activate. It will be
marked as active.
9
Define a Virus Scan Profile
- In the Visual Administrator choose the cluster Virus Scan Provider.
- On the Profiles tab create a new virus scan profile by choosing the New button.
- Type the name for the new profile (AVIRA) and confirm that with OK. The entered
name is automatically saved with the prefix “Z_”.
- Mark the node of the new profile.
Activate the Default option on the Settings tab, to set the profile as default and
eventually adjust the values described in the table below.
Default: When activated, the profile will be automatically selected.
Name: Name of the new profile.
Description: Description of the new profile.
Use reference: Leave this inactive. When activated, the other input fields would be
hidden.
10
As a virus scan profile can use another virus scan profile as a reference profile, it is
possible to operate multiple applications using the same virus scan profile. To create
a link to an existing reference profile, proceed as follows:
- Activate the option Use reference.
- Select a reference profile form the drop down list.

- To transfer the selection for the fields Group and Profile, choose Add.
- Configure the list with the buttons MOVE UP, MOVE DOWN and DELETE.
When checking for viruses, the list is processed from top to bottom with the linkage
from the Linkage field.
- To save the profile, press Set.
To activate the profile, select it and choose Activate.
11
Check the Configuration
- You can use the test applet provided by SAP NetWeaver, to check the functionality
of the Virus Scan Service.
- Open an Internet browser and type the following address:
http://[Server IPAdresse]:[Instanz-Port]/vscantest
Click the link to Test servlet.
12
- Select the EICAR Anti-Virus Test File under Object to Be Checked.
- Select the (default) profile under Scanner Selection.

Active: Select the checkbox to activate the Virus Scan Service in KMC.
Check Write: Specifies if the virus scan should occur only at download, or at upload,

Clean Viruses: When active, the antivirus tries to clean infected files.
Positive List: When active, the virus scanner checks ONLY the selected
repositories.
File Count: Maximum number of files to be scanned simultaneously. (default: 10)
Maximum File Size (MB): Maximum size of the files to be scanned. Bigger files
cannot be loaded in the Knowledge Management, for safety reasons. It depends on
the File Count and Path for Temporary Files.
For example, if you set the maximum size to 1000 MB and the File Count is 10, the
temp directory should be 10 GB.
24
Memory Count: Sets the number of memory blocks available to the scanner.
Default: 10.
Memory Limit (KB): Sets the maximum size of the memory space allowed for
the files being scanned. Default: 1000.

selected repositories. Otherwise, the scanner checks all repositories, EXCEPT the
selected ones.
Virus Scan Profile: Select the profile to be used (AVIRA).
Path for Temporary Files: Specifies the temporary folder for the files to be scanned
(C:\Windows\Temp). If this option is left empty, the default value of the Java engine is
used (java.io.tmpdir).
