Is GIMR worth installing in 19C ?

Tom Member Posts: 209

OS: Oracle Linux 7.7

GI/RDBMS version : 19c

I have only worked in GI. So, my team and I never had to install MGMTDB repository DB in our shop.

Now, I need to build a 3-node production RAC DB.

As I understand, Grid Infrastructure Management Repository (GIMR) is not mandatory to install in 19C.

So, is it worth installing in 19C ?

    Yes, its worth installing. And actually you don't have to do anything on your end. Just install the Grid Infrastructure software and the wizard will take care of it for you.

    Why would you not want to have the GIMR?

    Yes, its worth installing.

    Every Oracle Standalone Cluster and Oracle Domain Services Cluster contains a Grid Infrastructure Management Repository (GIMR), or the Management Database (MGMTDB). The Grid Infrastructure Management Repository (GIMR) is a multitenant database with a pluggable database (PDB) for the GIMR of each cluster.

    I had two times an issue during patch caused by the MGMTDB (both times it was in the postpatch operation so not too bad because the system was patched but quite stressful). Also on some cluster the stop of crs takes very long, it seems to be related to chad service that times out.

    Since we get nothing in exchange for this MGMTDB I consider to delete it (but there is no official document about removing). For new system I would avoid to install it.

    It is sad because at the starts there were big expectations on cluster health advisor, but at the end we got only troubles. Also there is the AHF which is completly unusable and with zero support.
