Problems with Backup and Restoration

Problems might occur when you attempt backup or restoration.

The following solutions apply to problems with backup and restoration operations for Oracle SOA Cloud Service.

Oracle Traffic Director is not backed up

Typically, this occurs when the traffic director is currently busy servicing other requests.

Verify that Oracle Traffic Director is running and in a healthy state, and try backup again.

To check the health of the Oracle Traffic Director:

1. In the Oracle SOA Cloud Service Console, click for the desired service instance and select Open Load Balancer Console. Log in using the credentials defined when provisioning your service instance.

2. In the left panel, click Services.

   The Services page is displayed on the right.

3. Click on the Configurations tab in the upper left corner of the console and select opc-config.

   The Configuration table is displayed.

4. Notice whether a green check mark appears in the cell containing the load balancer name.

   If there is a green check mark next to Instance Running, your load balancer is running and healthy. Otherwise, your load balancer is not running.

There is not enough space for my backup

The backup storage area does not have enough space for the backup operation to create the archive.

To check for available space, log in to the VM and check the size of the backup mounted directory under /u01/data/backup. See Access a VM Through a Secure Shell (SSH).

If there is not enough space for the backup, do one of the following:

• Delete any unwanted backups.

• Archive one or more backups to an Oracle Cloud Infrastructure Object Storage Classic container. See Backup and Restore in REST API for Oracle SOA Cloud Service.

Then increase the storage volume size used by the fast recovery area as necessary if you have a longer retention policy and extend the backup storage volume as described in  Administering Oracle Database Classic Cloud Service.

The restoration operation fails and generates an error about pre-check failure

Either one or more servers are currently unreachable, or there is not enough space on one of the storage volumes.

To find the reason for the restoration failure:

1. Navigate to the Backup page.

   1. In the Oracle SOA Cloud Service Console, click the name of the service instance for which you want to find the restoration status information.

   2. On the Overview page, click the Administration tile.

      The Oracle SOA Cloud Service Instance page is refreshed with the Administration tile in focus.

   3. Click the Backup tab.

      The Backup page is displayed.

2. Locate the icon for the restoration that failed.

3. Click on the date to the right of the icon.

   A pop-up containing the status details is displayed.

If the problem is that a server is unreachable, the software automatically attempts a scale-in operation. Try restoring the service again.

If there is not enough space for the backup, do one of the following:

• Delete any unwanted backups.

• Archive one or more backups to an Oracle Cloud Infrastructure Console Object Storage Classic container. For more information, see Backup and Restore in REST API for Oracle SOA Cloud Service.

One of my backups is showing a warning icon

When a scheduled backup is completed, Oracle SOA Cloud Service tries to move older backups from block storage and delete older backups from the Oracle Cloud Infrastructure Object Storage Classic container. If Oracle SOA Cloud Service cannot move or delete the older backups, the newly completed backup shows a warning icon:

This problem does not affect the newly completed backup. However, the presence of the older backups may cause future backups to fail because of insufficient space.

To prevent such failures, ensure that Oracle SOA Cloud Service can remove the older backups when the next scheduled backup is completed:

1. To find out why Oracle SOA Cloud Service could not move or remove the backups, place the cursor over the icon.

   A text rollover appears that contains detailed information about why Oracle SOA Cloud Service could not move or remove the backups.

2. Correct the problem that prevented Oracle SOA Cloud Service from moving or removing the backups.

   For example, to correct an access permission problem, ensure that the user name and password for the administrator of the Oracle Cloud Infrastructure Object Storage Classic container are correct. If necessary, change them as explained in Configure Automated Backups for an Oracle SOA Cloud Service Instance

3. When the next scheduled backup is completed, determine whether it shows the icon for a successful backup:

   • If so, no further action is required.

   • If the next scheduled backup also shows the warning icon, contact Oracle Support Services.
