Restore and Recover Corrupted Embedded UMS DB

Environment

If the embedded databse of UMS* is corrupted, try the following measures to resolve the issue.

*The underlying technology of the embedded database is Apache Derby.

Restoring a Database Backup Made with the UMS Administrator

If a backup of the embedded database is available, just restore the backup, see Restoring a backup.

Restoring a File-Based Backup

If an uncorrupted copy of the database files located under C:\Program Files...\IGEL\RemoteManager\db\rmdb (default installation path on Windows) and/or /opt/IGEL/RemoteManager/db/rmdb/ (default installation path on Linux) is available, you can restore the file copy. In the remainder of this how-to, the aforementioned possible paths will be referred to as RMDB_PATH.

To restore the backup, perform the following steps:

  1. Open the UMS Administrator, and go to Data Source in the menu on the left.
  2. In the Data Source area, delete the corrupted Derby DB.
  3. Create a new embedded DB with exactly the same user name and password as you used for the deleted DB.
  4. Deactivate the newly created DB.

    In addition to this, shutdown the UMS service.

    On Windows, the UMS service can be shutdown in the Windows Service Manager. Alternatively, start a command prompt with administrator privileges and issue the command net stop igelrmguiserver.

    On Linux, the way the UMS service is shutdown depends on the Linux distribution. Refer to your distribution's manual to learn how to shutdown services.

  5. Erase all files contained in the folder at RMDB_PATH.
  6. Copy your previously backed-up files to RMDB_PATH.
  7. Activate the DB with the UMS Administrator under Data Sources.
  8. Wait 1 - 2 minutes, then log in to the UMS console.
