Question
You get complaints from users of several different applications that performance has degraded over time. These applications run in this configuration: 1. There is one database and database instance, which is an Oracle 12c multitenant Container Database (CDB) with five Pluggable Databases (PDBs). 2. One of the poorly performing applications run in one of the PDBs. 3. One of the poorly performing applications runs in a different PDB in the same CDB. 4. You have the Oracle Resource Manager configured for the CDB only. 5. Each PDB has all sessions in one consumer group. A check of wait events for the sessions belonging to these applications shows that the sessions are waiting longer and that there are more sessions from other applications in the same database instance.
