10.1 Backout Setup

Identify IP addresses of all servers that need to be backed out.

  1. Expand Administration select Software Management click Upgrade.
  2. Based on the Application Version column, identify all the host names that need to be backed out.
  3. Expand Configuration click Servers.
  4. Identify the IMI IP addresses of all the host names identified in step 2. These are required to access the server when performing the back out.

The reason to run a back out has a direct impact on any additional back out preparation that must be done. The back out procedure causes traffic loss. All possible reasons cannot be predicted ahead of time.

Note:

Verify the two backup archive files created in using Full Database Back up (PROV and COMCOL ENV for All Servers) are present on every server that is to be backed-out.

These archive files are located in the /var/TKLC/db/filemgmt directory and have different file names from other database backup files.

The file names have the following format:

  • Backup.<application>.<server>.FullDBParts.<role>.<date_time>.UPG.tar.bz2
  • Backup. <application>.<server>.FullRunEnv.<role>.<date_time>.UPG.tar.bz2
