Using Grid Control Repository for RDBMS Patch Report

By | May 19th, 2011 | Category: Oracle Database, Oracle Enterprise Manager | No Comments »

I was looking for a method to utilize the Grid Control Repository, which contains information about installed Oracle Homes, databases and patches, for a patch report.

With a little reverse engineering i came up with these relevant tables:

  • Mgmt_Ecm_Snapshot: Every time the inventory is refreshed, a new line is inserted into this table containing the host name and the snapshot_guid. The most current snapshot has flag IS_CURRENT set to ‘Y’
  • Mgmt_Inv_Container: Every Oracle Home is a container. This table contains the snapshot_guid and the container_guid along with a container_description which is basically the Oracle Home Path
  • Mgmt_Inv_Patch: This table contains container_guid, Patch ID and patch installation timestamp
  • Mgmt_Inv_Component: This table lists all the components of the oracle homes along with their version. There is one component per container with the flag Is_Top_Level set to ‘Y’.  We use this component for getting the base version of the installed product. (e.g. 11.2.0.2)
  • Mgmt_Inv_Versioned_Patch: I am not sure if this table is needed for version information, but one of the mgmt views was using these two tables together, so I used it as a reference.

The complete statement now is:
