Policy Server : Session Store tuning questions for performance

Products

• SITEMINDER
• CA Single Sign On Federation (SiteMinder)

Issue/Introduction

 

When running a Siteminder Policy Server with CA Directory Session Store, which are the best values to set to the configuration of the Session Store (1)?

 

Environment

 

Policy Server 12.8SP5 on RedHat 7

 

Resolution

 

As per documentation, it's recommended to set these Policy Server registry keys if your environment expects a high volume of transactions. We recommend using the default values first and then benchmarking the environment to detect the possible bottlenecks. If bottlenecks are detected, then analyze the problem to point out which aspect of the processing is causing delays. All those parameters help to solve performance problems.

The same approach is valid to set the MaxConnections value too.

    Configure Symantec Directory as a Session Store

      Add the following registry keys that affect the performance of an

      registry location, and customize their values as required:

      SessionUpdateGracePeriod
      MaxConcurrentDeletes
      MaintenanceQueryRowLimit
      EnableFlushUserCmdOnLogout

      [...]

      Connection Pools

      To increase the size of the session store connection pool, modify
      the value MaxConnections registry setting, which can be found at the
      following registry location:
