IBM Business Monitor tuning
A set of configuration options are relevant for tuning IBM Business Monitor.
- Configure Java heap sizes
The default initial and maximum heap sizes in most implementations of Java™ are too small for many of the servers in the Business Process Management configuration. IBM Business Monitor and its prerequisite servers are installed with larger heap sizes, but you might find it beneficial to check that these sizes are appropriate for your hardware and workload.- Configure CEI
By default, when an event arrives at Common Event Infrastructure (CEI), it is delivered to the registered consumer (in this case, a particular monitor model) and also into an additional, default queue. Unless this extra queue is needed, you can prevent it from being made.- Configure work manager maximum threads
The processing of incoming events for a model is done through the use of several work manager thread pools. You can change the value of the Maximum number of threads property for the work managers to get full use of all available processors on an IBM Business Monitor server.- Enable KPI caching
The cost of calculating aggregate KPI values increases as completed process instances accumulate in the database. A KPI cache is available to reduce the number of these calculations.
