About Tuning SSSE for Optimal Performance

In general, SSSE works well when you configure your Siebel implementation using the scalability and sizing recommendations that are discussed in Siebel Performance Tuning Guide. For example, you can set parameters such as MaxMTServers and MinMTServers for the PIMSI Engine component to the values that suit your implementation as a whole, without especially considering SSSE performance issues. However, this topic discusses some configuration recommendations that are particularly important for ensuring optimum performance for SSSE.

MaxTasks

The MaxTasks setting controls the total number of PIMSI Engine jobs that can run simultaneously on a single Siebel Server computer. The value you choose for the MaxTasks parameter can limit the total number of connector instances that run at any one time, preventing the connector computers from becoming overloaded.

Choosing an Appropriate Dispatcher Repeat Interval

When you are satisfied with your MaxTasks setting values, you might want to measure how quickly SSSE can process your entire population of ongoing SSSE users. You can use the information to adjust the values of the Repeating job settings for the PIMSI Dispatcher job, so that the Dispatcher runs at an interval of your choosing. Dispatcher jobs must not overlap. To ensure that this does not occur, set the Repeat From field of the repeating job to End. This ensures that each PIMSI Dispatcher cycle does not start until a specified interval after the previous PIMSI Dispatcher cycle has completed.
