Perform a major compaction

You can immediately initiate a major compaction for an idle tenant. When an error occurs during the major compaction of the tenant, you can perform troubleshooting, clear the error, and then continue the major compaction.

Prerequisites

• Make sure that you have the following permissions:

  • Resource Permissions : Cluster Maintenance or Tenant Maintenance permission
  • Menu Permissions : Permission on the Compaction Management menu of Tenants

• You can initiate a major compaction only for a primary tenant. The major compaction for a standby tenant is automatically triggered after the standby tenant synchronizes the major compaction status of the primary tenant. You cannot manually initiate a major compaction for a standby tenant.
