How can you restore the installation history in IBM Installation Manager after you reinstall IBM Installation Manager?
Note: This document contains a procedure that might be better handled by using the "imcl -reinstallIM" command-line function of Installation Manager, which you should try before using these steps. Use of the following steps should be considered a last resort.
IBM Installation Manager keeps a history of the applications that it has installed on a machine. If IBM Installation Manager must be completely re-installed, the ability to import or restore the previous history is required; otherwise, all of the applications must be re-installed. To restore the installation history, complete the following steps:
- Rename the /etc/.ibm/registry/InstallationManager.dat file to /etc/.ibm/registry/InstallationManager.datOLD
- Make a backup copy of the /var/ibm/InstallationManager directory just in case, but leave the original /var/ibm/InstallationManager directory in place. The /var/ibm/InstallationManager directory is the IBM Installation Manager application data location that contains all the important IBM Installation Manager product install history information.
- Rename the old IBM Installation Manager install location (by default) /opt/IBM/InstallationManager to /opt/IBM/InstallationManagerOLD
- Install the latest version of IBM Installation Manager as a fresh IBM Installation Manager install. There is no need to use the -reinstallIM option.
When the new IBM Installation Manager is installed, launch it and check to make sure everything is in order, and the history is there. A good command-line check is:
You should see output similar to this text:
[root@linux4627 tools]# ./imcl version
Installation Manager (installed)
Internal Version: 126.96.36.19920831_1216
If everything is working as desired, you can safely delete the renamed files, renamed directories, and backup files that you used in the previous steps.
