Roll Back a Patch or Failed Patch

You can roll back the last patch or failed patch attempt on a cluster by using the Patching page in the service console for Oracle Big Data Cloud.

To roll back the last patch or failed patch attempt:

1. Open the service console. See Access the Service Console for Big Data Cloud.
2. Click the name of the cluster on which you want to roll back a patch.

   The Big Data Cloud Overview page is displayed.

3. Click the Administration tile and then click the Patching tab.

   The Big Data Cloud Patching page is displayed.

4. Click Rollback.

   The Patching page redisplays, showing a status message that your request has been submitted, the Administration tile shows the starting time of the rollback operation, and a Rolling back... message replaces the Rollback button.

   Note:

   Rollback operations are performed with a minimum of impact on the functioning of the cluster. However, during part of the operation the cluster is shut down for a period of time, thus making it inaccessible.

5. Refresh the Patching page occasionally to update the status message.

   Note that the rollback operation can take several minutes to complete.

   When the rollback operation completes, the Administration tile shows the completion time of the operation, and a log of the operation’s activities appears in the Details of Last Patching Activity section.
