Restoring a repository from backup

Restore the service and configuration information in your repository in the case of accidental deletion of data or hardware failure. Use this topic to restore your repository from a backup that was initiated from the manager or that was made by using the UNLOAD command of the Informix® DB-Access utility.

Only users with a user role of admin can restore a repository. A restore completely overwrites the repository databases with the contents of the chosen backup. The repository is unavailable while the restore is running, and the manager must be restarted on the application server after the restore completes.

By default, backups are stored in /opt/IBM/InfoSphere/Optim/repo/server/ids11750/backups on the repository computer. Backup files are named backup_yyyymmddhhmmss_L0 or backup_yyyymmddhhmmss_L1, where yyyymmddhhmmss is the date and time at which the backup was made. Backup files with an L0 suffix are full backups, and backup files with an L1 suffix are incremental backups. To use an incremental backup, the backup folder must also contain the full backup on which the incremental backup is based.

To restore a repository:

  1. If necessary, copy the backup files to the backup folder on the repository computer.
  2. Access the manager on the application server.
  3. Click Configuration.
  4. Click Repository.
  5. Click Administration.
  6. Click Restore Repository.
  7. Select the backup to use and click Restore.
After the restore completes, access the application server console and restart the manager WAR.
