How to disable JBPM persistence? #8

Open sakella1986 opened 7 years ago

I have an existing JBPM project and JPA persistence is enabled. I would like to disable the JBPM persitence functionality. I tried removing all the tables from Persitence.xml file and it is not working.

Could someone provide steps to disable JPA persistence so that I dont need to use any of the tables and improve performance. Rightnow we are using HSQL in-memory database for JBPM with hibernate and JAVA EE CDI framework.

I would like to use PostgresSQL for this. What is the recommended database for JBPM?
