5.1.4 IORM Cluster Plan
Oracle Exadata System Software release 21.2.0 extends I/O Resource Management (IORM) to include the cluster plan. The IORM cluster plan specifies how storage server resources are allocated across multiple Oracle Grid Infrastructure clusters. Each directive in a cluster plan specifies an allocation to an Oracle Grid Infrastructure cluster, rather than an individual database or consumer group.
For example, consider a system hosting two clusters;
clusterA
and clusterB
. Now, imagine a cluster plan
with share-based resource allocation where clusterA
has three shares,
and clusterB
has one share. In that case, and in the absence of any
other IORM plans, all of the databases running in
clusterA
share 75% of the I/O resources, while the databases in
clusterB
share the remaining 25%.
Minimum requirements:
- Oracle Exadata System Software release 21.2.0
- To operate the IORM cluster plan, ASM-scoped security must be configured.
