What is the expected behavior?

BE-Engine should not get started and shut down automatically.

What is the actual behavior?

If invalid keyspace name is provided, exception is thrown for the same but BE-Engine also gets started. Since keyspace is not valid, BE-Engine also should not get started. Please find attached logs for the same.

Please provide log files.

We are already throwing runtime exception from 'Connect' catalog function.

2023 Apr 03 17:41:45:540 GMT +05 Cass_store_func_Test_invalid_keyspace ERROR [main] - [runtime.service] [inference-class] Got runtime exception while invoking Action com.tibco.cep.runtime.session.impl.RuleFunctionsExecAction@11c25846 Objects <>
java.lang.RuntimeException: Error occurred while connecting to Store with url[10.69.136.106:9042]

Expected behaviour can be achieved by handling this exception in BE code. To shutdown engine - user can make use of Engine.shutdown catalog function.

As discussed with Rashmi if exception is thrown for any invalid combination then Engine will remain start, however if customer needs they can use Engine.Shutdown() catalog function inside try catch block in their codebase.
