IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Summarization and Pruning Agent
The Summarization and Pruning Agent is a multi-threaded, Java based application. It interacts with the warehouse using a JDBC driver appropriate for the database of the warehouse. The number of worker threads available and the heap size of the JVM affect the performance of the Summarization and Pruning Agent and the length of time of its processing runs.
The installation location of the Summarization and Pruning Agent is another important aspect of Summarization and Pruning Agent performance tuning.
On Windows, the Summarization and Pruning Agent environment parameters are set in the following configuration files according to operating system:
Whenever maintenance or reconfiguration takes place in your environment, these files might be recreated, and configuration changes can be lost and require reapplication.
- ITM_HOME\TMAITM6\KSYENV
For example: C:\IBM\ITM\TMAITM6\KSYENV
- ITM_HOME/config/sy.ini
For example: /opt/IBM/ITM/config/sy.ini
See
- Number of worker threads
- Set the maximum Java heap size
- Enable more detailed trace in log files
- Consider disabling shifts and vacations
- Minimize the number of summarization intervals used
- Set the max worker threads and max rows per transaction appropriately for your environment
