Performance tuning can be a complex task. It is often time-consuming and requires different subject matter experts to work together closely. Tuning IBM Business Process Manager (BPM) systems for performance, in particular, requires knowledge of the modeled business processes all the way down to the Java Virtual Machine (JVM), the database, and sometimes even the hardware layers.
The need for tuning a system can have different drivers. In a best-case scenario, tuning is part of your project plan from the start. But sometimes, issues arise in the production system due to changes to the planned workload or less-than-optimal system maintenance.
Yet regardless the drivers, there are five basic things to consider when tuning an IBM BPM system (see figure).
1. Apply a tuning methodology
To achieve the best results in a reasonable amount of time, follow a structured, method-based tuning process. A basic, high-level tuning methodology includes these steps:
2. Review the applications
Review the BPM applications and apply perf
