Purging data in IBM Business Process Manager

IBM® Business Process Manager is a stateful product that accumulates data over time. As with any stateful product, it's essential to its ongoing health to have a strategy for purging some of that state occasionally. This article explores the areas of IBM BPM where data is collected and the methods that exist today to purge that data. This content is part of the IBM Business Process Management Journal.

If data grows without bounds, it can over time lead to disk space issues and to performance issues as database queries take ever longer. In this article, we cover all the areas where IBM BPM collects data either in a database or in the file system. We point out where information is specific to IBM BPM Advanced or Standard editions, and provide release-specific information. We go back as far the V7.5.1.1 release of IBM, though much of what is stated there will apply to the predecessor WebSphere Process Server and WebSphere Lombardi Edition products.

We will cover the following topics in this article:

• Process Center projects and snapshots
• Process Server process and task instance data
• Performance Data Warehouse event data
• Some additional secondary data that can accumulate, though not as fast as the above
• IBM Business Monitor, a complementary product to IBM BPM.
