 I got the following message:
Failed to connect to database instance: ORA-04031: unable to allocate 1784 bytes of shared memory ("large pool","unknown object","session heap","kpuinit env handle") (DBD ERROR: OCISessionBegin).
Severity=Critical

This is test database.  In production we have 500 mb in shared_pool and 300 mb in large_pool.

In Uat we have 1 gb shared_pool and 112 mb in large_pool.

What I did is in Test - I re-distributed 400 mb in large_pool and 800 mb to the shared_pool.

Also I saw note # 4118188.8 (Bug) which mentioned that jdbc connections uses large pool for dedicated connections.

This query returns the following jdbc connections from test:  In test instead of "NONE" you see "DEDICATED".

Howdy, Stranger!
