6.2. Setup Indexes

Setup Foreign Key Indexes

Some databases, for instance Oracle and PostgreSQL, do not automatically create an index for each foreign key. This can result in deadlocks occurring. To avoid this situation, it is necessary to create an index on all foreign keys, especially in the Oracle database.

Setup Indexes for Process and Task Dashboard

Process and Task Dashboard in 6.1 has been refactored in order to cope with high volume of task and process instances. In order to get good response times while querying the database the following JBoss BPM Suite tables need to be indexed: processinstancelog and bamtasksummary.

Note that ALL the columns in these two tables need to be indexed and not just the primary and foreign keys.
