Restoring a database backup on a Linux system

If data loss or data corruption occurs, you can restore Unified Manager to the previous stable state with minimum loss of data. You can restore the Unified Manager database to a local or remote Red Hat Enterprise Linux or CentOS system by using the Unified Manager maintenance console.

Before you begin

About this task

The restore feature is platform-specific and version-specific. You can restore a Unified Manager backup only on the same version of Unified Manager. You can restore a Linux backup file or a virtual appliance backup file to a Red Hat Enterprise Linux or CentOS system.

Tip: If the backup folder name contains a space, you must include the absolute path or relative path in double quotation marks.

Steps

  1. If you are performing a restore onto a new server, after installing Unified Manager do not launch the UI or configure any clusters, users, or authentication settings when the installation is complete. The backup file populates this information during the restore process.
  2. Using Secure Shell, connect to the IP address or fully qualified domain name of the Unified Manager system.
  3. Log in to the system with the maintenance user (umadmin) name and password.
  4. Enter the command maintenance_console and press Enter.
  5. In the maintenance console Main Menu, enter the number for the System Configuration option.
  6. In the System Configuration Menu, enter the number for the Restore from a Unified Manager Backup option.
  7. When prompted, enter the absolute path of the backup file.
    Example
    Bundle to restore from: /data/ocum-backup/UM_9.4.N151113.1348_backup_rhel_02-20-2018-04-45.7z
    After the restore operation is complete, you can log in to Unified Manager.

After you finish

After you restore the backup, if the OnCommand Workflow Automation server does not work, perform the following steps:
  1. On the Workflow Automation server, change the IP address of the Unified Manager server to point to the latest machine.
  2. On the Unified Manager server, reset the database password if the acquisition fails in step 1.
