About the Grid Infrastructure Management Repository

The Grid Infrastructure Management Repository (GIMR) is a multitenant database with a pluggable database (PDB) for the GIMR of each cluster.

Note:

Starting with the Oracle Database 19c Release update for April 2026 (19.31), the Quality of Service Management feature in Oracle 19c is desupported.

Every Oracle Domain Services Cluster contains a Grid Infrastructure Management Repository (GIMR). However, GIMR configuration is optional for Oracle Standalone Cluster. The GIMR stores the following information about the cluster:

  • Real time performance data that Cluster Health Monitor collects

  • Fault, diagnosis, and metric data that Cluster Health Advisor collects

  • Cluster-wide events about all resources that Oracle Clusterware collects

The global GIMR runs in an Oracle Domain Services Cluster. Oracle Domain Services Cluster locally hosts the GIMR in a separate Oracle ASM disk group. Oracle Member Cluster for Database uses the remote GIMR located on the Oracle Domain Services Cluster. Hosting the GIMR on a remote cluster reduces the overhead of running an extra infrastructure repository on a cluster. The GIMR for an Oracle Domain Services Cluster is a multitenant database with one PDB, and additional PDB for each member cluster that is added.

When you configure an Oracle Domain Services Cluster, the installer prompts to configure a separate Oracle ASM disk group for the GIMR, with the default name as MGMT.
