EM 12c: Enterprise Manager 12c Cloud Control Repository Database Suffers Excessive Application Waits on UPDATE EM_CURRENT_DEPLOYED_PLUGIN Statement (Doc ID 1943149.1)

Last updated on NOVEMBER 20, 2014

Applies to:

Enterprise Manager Base Platform - Version 12.1.0.4.0 and later
Information in this document applies to any platform.

Symptoms

12.1.0.4.0 OMS. OMS and Repository are on different Host.
The Repository database is monitored with a 12.1.0.3.0 agent.

The 12.1.0.4 Repository database is experiencing a continuous deadlock, the same symptoms as described in this reference:

Note 1933996.1 EM 12c: Deadlocks and blocking sessions against Repository Database After the Agent Upgrade to 12.1.0.4

In this case, Patch 19458672, the prescribed solution in 1933996.1, has already been applied to the OMS Oracle Home.

The Repository database suffers excessive waits on this statement:

UPDATE EM_CURRENT_DEPLOYED_PLUGIN SET PLUGIN_VERSION_ID = :B7 , RELATIVE_HOME = :B6 , DEPLOYED_DATE = :B5 WHERE PLUGIN_VERSION_ID = :B4 AND DEST_TYPE = :B3 AND PLUGIN_BITS_TYPE = :B2 AND DEST_ID = :B1
