Configure Policy Server Clusters

The CA SSO Agent for Siebel supports clusters of Policy Servers to improve performance.

Follow these steps:

1. Navigate to the following directory:

   <Siebel_Agent_Install_location>/siebel/bin
   

2. Locate the files for your operating environment from the following list:

   Windows

   Uses the following libraries:

   • smcommonutil.dll
   • smerrlog.dll

   Solaris and AIX

   Uses the following libraries:

   • libsmcommonutil.so
   • libsmerrlog.so

   HP-UX

   Uses the following libraries:

   • libsmcommonutil.sl
   • libsmerrlog.sl

3. Copy the libraries for your operating environment to the following directory:

   Siebel_ROOT/siebsrvr/bin
   

4. Open the following file with a text editor:

   SmSiebelSSO.conf
   

5. Add the following parameters (on separate lines) with the values you want:

   Clusters

   Specifies the IP addresses of several Policy Servers that are separated into smaller groups of clusters which help to improve performance. Separate individual Policy Servers in a cluster with spaces. Separate clusters with semicolons.

   Example: 127.0.0.100 127.0.0.101 127.0.0.102; 192.168.2.100 192.168.2.101 192.168.2.102;

   ClusterThreshold

   Specifies the minimum percentage of available Policy Servers within a cluster. If the number of available Policy Servers within a cluster falls below this number, failover to the next cluster occurs. For example, if each cluster contains six Policy Servers, and the ClusterThreshold is 50, then failover occurs if more than three of those Policy Servers in the cluster are not available. When the value of this parameter is set to zero, all Policy Servers in a cluster must fail before failover occurs. When the value of this parameter is set to 100, failure of one Policy Server in a cluster triggers failover to the next cluster.

   Default: 0

   Limits: 0—100

6. Locate the line with the PolicyServer parameter, and add a comment character at the beginning.
7. Save and file and close the text editor.

   Policy Server clusters are configured.

   Note: If you decide not to use Policy Server clusters in the future, remove the comment character from the PolicyServer line. Add comment characters before the lines of the parameters in Step 2.
