About Backing Up and Restoring an Oracle Integration Classic (User-Managed) Instance

By backing up your Oracle Integration Classic (user-managed) instances, you can preserve them in a particular state..

When you create an Oracle Integration Classic instance, you can choose whether or not to enable backups. These backups are recorded to local node storage as well as to an Oracle Cloud Infrastructure Object Storage Classic container.

What a Backup Contains

The contents of a backup depend on whether it is a full backup or an incremental backup.

A full backup contains all the runtime artifacts required to restore the instance’s configuration data. An incremental backup contains changes to configuration data on all nodes since the last scheduled full backup.

Note:

All incremental backups are automated scheduled backups. You cannot create an incremental backup on demand.

Contents of a Database Backup

A database backup contains Oracle database instance Oracle Fusion Middleware component schemas, and application data for an Oracle Integration Classic instance.

Note:

Only scheduled automated backups of an Oracle Integration Classic back up the database instance. On-Demand backups do not perform a database backup. Alternatively, you can back up your database using the associated Oracle Database Cloud Service database used by the instance.

Where Backups Are Stored

Oracle Integration Classic stores all backups in an Oracle Cloud Infrastructure Object Storage Classic container. To speed up restorations from recent backups, Oracle Integration Classic also keeps a local copy of any backup it has recently created.

Note:

Do not attempt to download the backup files generated by Oracle Integration Classic. These files are encrypted and not accessible offline. You must use Oracle Integration Classic to restore an instance from a backup.

By default, Oracle Integration Classic stores backups in the container that was specified when the instance was created.

Oracle Integration Classic automatically deletes a backup when the retention period for the backup has elapsed.

How Local Copies of Backups Are Stored

Oracle Integration Classic stores local copies in a dedicated volume mounted on the block storage attached to the node where the Administration Server is running.

For an incremental backup, Oracle Integration Classic stores the local copy for seven days before deleting it.
For a full backup, Oracle Integration Classic stores the local copy for seven days, or as long as the local copy of its last related incremental backups was stored, whichever is longer.

How Backups and Local Copies Are Deleted Automatically

After completing the day’s scheduled backup, Oracle Integration Classic deletes any backups or local copies that are due to be deleted that day. If the scheduled backup fails because of insufficient space, backups and local copies that are due to be deleted will still be deleted.

Note:

When an Oracle Integration Classic instance is deleted, all its backups are deleted.

What Happens During a Backup

During a backup of an Oracle Integration Classic instance, the instance continues to run and all applications deployed to the instance remain available.

To prevent configuration changes during a backup, Oracle Integration Classic locks the Oracle WebLogic Server domain if the administration server is running. After locking the domain, Oracle Integration Classic backs up files on each node.

While the backup is in progress, you cannot start any other management operation on the instance. Similarly, if the administration server is not running at the time a backup is started, do not attempt to start this server until the backup completes.

When the backup is complete, Oracle Integration Classic unlocks the Oracle WebLogic Server domain. If the backup is a scheduled backup, Oracle Integration Classic also cleans up older backups as follows:

From local storage it deletes all backups old enough to be stored only in the Oracle Integration Classic container.
From all storage locations it deletes any remaining copies of backups whose retention period has elapsed. The default is 30 days.

What Happens When an Instance Is Restored

When restoration of an instance is initiated, Oracle Integration Classic shuts down the servers in the instance. After the restoration is complete, Oracle Integration Classic restarts these servers.

If the instance contains any managed server nodes that are not in the backup, Oracle Integration Classic warns you that it cannot restore these nodes.

Before trying to restore again, you can scale in the instance to delete these nodes.

If you choose to continue without scaling in the instance, Oracle Integration Classic asks you to confirm that you understand that the instance will be scaled in automatically.

If the backup contains any managed server nodes that are not currently in the instance, Oracle Integration Classic does not attempt to remove these managed servers from the Oracle WebLogic Server domain. You must use the WebLogic Server to manually remove these managed servers from the domain configuration after restoring the instance.

Oracle Integration Classic does not automatically remove any existing Oracle WebLogic Server transaction records after restoring an instance from a backup.

Configure an Automatic Backup for an Oracle Integration Classic (User-Managed) Instance

You can configure backups for an instance to customize when the Oracle Integration Classic (user-managed) instance is automatically backed up and how backups are stored.

Because the changes affect only one service instance, you can configure different values for these properties for each of your service instances. Specifically, you can customize the following properties of the service instance:

To configure automated backups for an Oracle Integration Classic instance:

Sign in to the Oracle Cloud Infrastructure Console.
Click in the top left corner of the Oracle Cloud Infrastructure Console.
Select Platform Services, then Integration Classic.
The Oracle Integration Classic Instances page is displayed.
Click the name of your Oracle Integration Classic instance.
In the Service Overview page, click the Administration tile.
Click the Backup tab.

The Backup page opens.

Description of the illustration ic_backup.png
Click Manage backups on this service next to Available Backups and select Configure Backups.

In the Configure Backups dialog, set the options to configure automated backups for the service instance.

In the Schedule section, set options to configure when automated backups are performed:

Note:

All times must be for the Coordinated Universal Time (UTC) time zone, not your local time zone.

Option	Description
Full Backup	From the drop-down lists, select the day of the week and the time of day UTC when you want full backups to be performed.
Incremental Backup	From the drop-down list, select the time of day UTC when you want incremental backups to be performed.

In the Set new retention period to field, enter the number of days that you want new incremental backups and full on-demand backups to be retained.

Note:
If you decrease the retention period, any existing backups that are older than this period will automatically be deleted during the next scheduled backup.

Full scheduled backups are retained until their last linked incremental backup is no longer available. The additional retention period for full scheduled backups is fixed and you cannot change it.

Click Save.

Initiate an On-Demand Backup

You can create a full backup immediately without having to wait for the next scheduled automatic backup.

Create a backup when making major changes to your Oracle Integration Classic (user-managed) instance, for example, in these situations:

Before any configuration changes that you may need to undo
Before deploying an application
After deploying an application

Note:

Do not attempt to start the administration server while a backup is in progress.

To initiate an on-demand backup of an Oracle Integration Classic instance:

Sign in to the Oracle Cloud Infrastructure Console.
Click the name of your Oracle Integration Classic instance.
In the Service Overview page, click the Administration tile.
Click the Backup tab.

The Backup page opens.

Description of the illustration ic_backup.png
Click Manage backups on this service next to Available Backups and select Back Up Now.
In the Back Up Now dialog, enter the notes up to 255 characters of free-form text to provide additional information about the backup.

This text is displayed in the Notes field for the backup in the list of available backups.
Click Back Up.

The Backup page is updated to show that the backup is in progress.

While the backup is in progress, you cannot start any other management operation on the service instance.

When the backup is complete, it is added to the list of available backups on the Backup page.

Disable or Enable Backups

Backups in an Oracle Integration Classic (user-managed) instance are enabled by default on a new service instance but you can disable and enable this feature as required.

After disabling backups for a service instance:

Scheduled backups will not run.
Automated backups will not run prior to patching or scaling operations.
You cannot take an on-demand backup.

Disabling backups for a service instance does not affect any backups that were taken previously.

Sign in to the Oracle Cloud Infrastructure Console.
Click the name of your Oracle Integration Classic instance.
In the Service Overview page, click the Administration tile.
Click the Backup tab.
Click Manage backups on this service next to Available Backups and select Disable Backups.
When prompted for confirmation click Disable Backups.
To enable backups again at a later time, return to the Backup page and click Enable Backups.

Restore a Backup

You can restore an Oracle Integration Classic (user-managed) instance from a backup to return the service instance to a particular state or recover the service instance after a loss of data.

Note:

If you restore a service instance's configuration files from a backup in which the hosts do not match the hosts in the service instance, Oracle Integration Classic handles the mismatch as follows:

If the service instance contains any managed server hosts that are not in the backup, Oracle Integration Classic warns you that it cannot restore the managed server hosts that are not part of the backup.

Before trying to restore again, you can scale in the service instance to delete the nodes that correspond to these managed server hosts. See Scale In an Oracle Integration Classic (User-Managed) Instance

If you choose to continue without scaling in the service instance, Oracle Integration Classic asks you to confirm that you understand that the service instance will be scaled in automatically.
If the backup contains any hosts that are not in the service instance, Oracle Integration Classic does not attempt to remove the managed servers on these hosts from the administration server configuration. You must use Oracle WebLogic Server to remove the managed servers on these hosts from the administration server configuration.

After you restore a service instance's configuration files from a backup that does not match the service instance, you might need to modify the restored service instance to return it to the state you require.

You can restore a service instance from an incremental backup without the need to restore the full backup to which the incremental backup is linked. In this situation, you are responsible for ensuring that the service instance is in a consistent state after the service instance is restored.

Restoration from a backup that is stored on block storage is faster than restoration from a backup that is stored in an Oracle Cloud Infrastructure Object Storage Classic container.

Before restoring an Oracle Integration Classic instance from a backup, you must disable the load balancer for the service instance.

The applications deployed to your instance will be unavailable during the restoration process.

To restore an Oracle Integration Classic instance from a backup:

Sign in to the Oracle Cloud Infrastructure Console.
Click the name of your Oracle Integration Classic instance.
In the Service Overview page, click the Administration tile.
Click the Backup tab.
Click Manage backups on this service next to Available Backups and select Restore.
You can restore an instance from an incremental backup without the need to restore the full backup to which the incremental backup is linked. Oracle Integration Classic instance restores all the data from the linked full backup required for a complete restoration of the instance.

Note:

If you choose to restore from an incremental backup, you are responsible for ensuring that the service instance is in a consistent state after the service instance is restored.
Enter Notes up to 255 characters of free-form text to provide additional information about the restoration, such as why you are restoring the instance.
Click Restore.

The Backup page is updated to show that the restoration is in progress. While the restoration is in progress, you cannot start any other management operation on the instance.

When the restoration is complete, it is added to the restoration history in the Backup page.

Delete a Backup

You can delete a backup that you no longer require to release storage or prevent an Oracle Integration Classic (user-managed) instance from being restored from the backup.

Note:

You can’t delete a full backup with linked incremental backups without deleting the incremental backups. If the backup you’re deleting has linked incremental backups, Oracle Java Cloud Service asks if you want to delete both the full backup and its linked incremental backups.

To delete a backup:

Sign in to the Oracle Cloud Infrastructure Console.
Click in the top left corner of the Oracle Cloud Infrastructure Console.
Select Platform Services, then Integration Classic.
Click the name of your Oracle Integration Classic instance.
In the Service Overview page, click the Administration tile.
Click the Backup tab.

The Backup page is displayed.
Click Manage backups on this service next to Available Backups and select Delete.
When prompted, confirm that you want to delete the backup.
If the backup you’re deleting has linked incremental backups, Oracle Integration Classic asks if you want to delete both the full backup and its linked incremental backups.
