I use the JBPM workflow in my project, and I have a small question regarding creating database patches or SQL statements to apply changes to the JBPM workflow.
The JBPM workflow currently provides a way to update JBPM tables in a schema by deploying the latest process definitions. However, what if my system is already working with a process definition deployed with state X, and now I have changed the process definition file to change X2. I still need to be able to deploy delta changes without interrupting instances of old saved data.
Is it possible to generate only “delta” database scripts to change the JBPM process definition? And what other good tools can you use to more intuitively modify process descriptions?
To repeat my problem, JBPM deploy cleans up the JBPM tables of the old instances supported there, and then redistributes the latest files; How do I create a delta without deleting old data? Are there any user-friendly tools for this?
Any help in this regard would be appreciated.
