Troubleshoot: Backup and restore the Java EE assets

While deploying the Java EE assets, you may encounter problems and require a roll back of the changes.

Implement a rollback strategy, in the case of an unsuccessful deployment. This strategy consists of the following tasks:

1. Backup the WC_ instance.ear.

2. Restore the backup copy of WC_ instance.ear.

Backup

To back up the WC_ instance.ear, you export the WebSphere Commerce. Complete the following steps:

1. Start the WebSphere Application Server administration server.

2. Launch the WebSphere administrative console.

3. In the WebSphere administrative console, expand Applications > Enterprise Applications.

4. From the Enterprise Applications list, select the check box next to the Java EE application for the instance. This will be WC_ instance (for example, WC_demo). Click Export.

   The system makes a master copy of the application; that is, a collapsed version of the WC_ instance.ear. The system merges it with the latest metadata from the deployment manager (if applicable) and exports it into an archived format.

5. Click WC_instance. Save the file to the computer.

Restore

To restore the backup of the WC_ instance.ear, you also use the export WebSphere Application Server:

1. Start the WebSphere Application Server administration server.

2. Launch the WebSphere administrative console.

3. In the WebSphere administrative console, expand Applications > Enterprise Applications.

4. From the Enterprise Applications list, select the check box next to the Java EE application for the instance. This will be WC_ instance (for example, WC_demo). Click Update.

5. On the Preparing for Application Installation page:

   1. Select Full applications.

   2. Specify the directory to the back up copy of the WC_instance.

   3. Select Generate Default Bindings and click Next.

   4. Click Continue.

   5. Click Summary.

   6. Click Finish.

6. The Updating Application page displays with a confirmation message. Click OK.

7. WebSphere Application Server saves the work. On the Updating page, click Save to Master Configuration to save the changes.
