View physical restore results

After a physical restore job is completed, you can view the restore results in views.

Procedure

1. Log on to the sys tenant of the cluster as the root user.

2. After a restore job is completed, execute the following statement to view the restore result:

   obclient [(none)]> SELECT * FROM oceanbase.CDB_OB_RESTORE_HISTORY\G
   

   The query result is as follows:

   The columns in the CDB_OB_RESTORE_HISTORY view correspond to those in the CDB_OB_RESTORE_PROGRESS view. The COMMENT column records the error information of a failed job.

   If the restore failed, you can cancel the restore by deleting the tenant. For more information, see Cancel restore.

What to do next

After the physical restore job is completed, the restored tenant is a standby tenant. You can perform the following operations:

• Run the recover command to replay logs from the source tenant. For more information, see Replay logs to a standby tenant.

• Execute the ACTIVATE statement to convert the standby tenant into the primary tenant. For more information, see Convert a standby tenant into primary tenant.
