Is serialization of kbase/package supported in BRMS 6/BPM Suite 6/RHDM 7?

Solution Verified - Updated

Environment

  • Red Hat JBoss BRMS
  • Red Hat JBoss BPM Suite
    • 6
  • Red Hat Decision Manager (RHDM)
    • 7

Issue

  • Building KieBase takes a long time. We are looking at options where a KieBase can be serialized/deserialized for subsequent use.
  • May I use DroolsObjectInputStream and DroolsObjectOutputStream?

Resolution

Serialization of kbase/package is not supported in BRMS/BPM Suite 6/RHDM 7.

From performance perspective, building kbase/package is a heavy operation but you can cache the kbase in memory (KieContainer automatically does it for you). So you will be able to re-use the kbase once built. As serialization is not supported, you cannot pass such a serialization form of kbase across JVM boots. So you need to build a kbase once after JVM boot anyway.

Note: Building a Kjar beforehand and loading it at runtime is rather a standard/recommended approach in BRMS/BPM Suite 6. It would improve the performance to some extent. But loading it may still take a long time because it's not fully serialized information. Further improvement is planned for RHDM 7.

DroolsObjectInputStream and DroolsObjectOutputStream were used in BRMS 5 but it's not supported in BRMS/BPM Suite 6/RHDM 7.
