5 min read
Oct 7, 2019

Whether Grid Infrastructure Management Repository (GIMR) database MGMTDB is required or not depends on the version of Oracle you are using. For 19c, GIMR is not required - About the Grid Infrastructure Management Repository However, GIMR is being created to test Fleet Patching and Provisioning (FPP). The following Oracle documentation is useful for creating GIMR - MDBUtil: GI Management Repository configuration tool (Doc ID 2065175.1) Download mdbutil.pl from Doc ID 2065175.1.
