I have blogged about the Grid Infrastructure Management Repository (GIMR) a while back:
And Markus Michalewicz, our Director of Product Management, Oracle Real Application Clusters (RAC), has published a very interesting and helpful insight article about GIMR on July 30, 2015. Read it here:
Since Oracle Database 126.96.36.199 the GIMR database will be created by default – and it is a single tenant database having a CDB$ROOT and one active PDB.
Recently the question came up if – in the likely event of applying a PSU or BP to the GI Home – you’ll have to run datapatch manually to adopt the SQL changes for the PSU/BP into the GIMR database as well?
Simple answer: No.
SQL changes will be automatically applied to the GIMR database by default. This got introduced in Oracle 188.8.131.52 with the PSU1 already and is tracked by ER BUG 14830129 – MGMT DATABASE PATCH ACTIONS NEED TO RUN DURING GI POST PATCH PHASE
You can verify this by looking at your logs (Thanks Santosh!) – you should see something similar as:

For all the skeptical people (Germans especially) let me add that in Oracle Database 18.104.22.168 the Grid Infrastructure Management Repository (GIMR) is not mandatory – but its existence will be mandatory for a future upgrade to Grid Infrastructure 12.2.
