本文详细介绍了Oracle独立集群中Grid Infrastructure Management Repository (GIMR)的作用与存储信息，包括实时性能数据、故障诊断数据、集群事件及QoS管理所需的CPU架构数据等。GIMR是一个多租户数据库，为每个集群提供了一个可插拔数据库(PDB)，并由Oracle ASM进行本地托管。

About the Grid Infrastructure Management Repository

Every Oracle Standalone Cluster contains a Grid Infrastructure Management Repository (GIMR), also known as 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. The GIMR stores the following information about the cluster:

Real time performance data the Cluster Health Monitor collects
Fault, diagnosis, and metric data the Cluster Health Advisor collects
Cluster-wide events about all resources that Oracle Clusterware collects
CPU architecture data for Quality of Service Management (QoS)
Metadata required for Rapid Home Provisioning

The Oracle Standalone Cluster locally hosts the GIMR on an Oracle ASM disk group; this GIMR is a multitenant database with a single pluggable database (PDB). You can optionally choose to configure two separate Oracle ASM disk groups, one for storing Oracle Cluster Registry (OCR) and voting files, and the other for the GIMR.
