Oracle Clusterware stores logs about resource failures in the cluster resource activity log, which is located in the Grid Infrastructure Management Repository.

Failures can occur as a result of a problem with a resource, a hosting node, or the network.

The cluster resource activity log provides precise and specific information about a resource failure, separate from diagnostic logs. The cluster resource activity log also provides a unified view of the cause of resource failure.

Use the following commands to manage and view the contents of the cluster resource activity log:

• crsctl query calog
  Query the cluster resource activity logs matching specific criteria.
• crsctl get calog maxsize
  To store Oracle Clusterware-managed resource activity information, query the maximum space allotted to the cluster resource activity log.
• crsctl get calog retentiontime
  Query the retention time of the cluster resource activity log.
• crsctl set calog maxsize
  Configure the maximum amount of space allotted to store Oracle Clusterware-managed resource activity information.
• crsctl set calog retentiontime
  Configure the retention time of the cluster resource activity log.
