Roll back a fix pack in silent mode
If the fix pack that you installed is not working, we can uninstall it in silent mode.
Create a response file for this task by running a simulated rollback. See Create a response file.
Instead of generating a new response file, we can edit the default response file that is provided with the product. However, if you edit the default response file, add encrypted passwords to the file. See Create encrypted passwords for a response file.
A silent rollback uses a response file to automate the removal of a fix pack.
To change the paths to the response file and log file, edit the lc_install.ini file.
To perform a silent rollback:
- Stop all clusters and node agents in the deployment but leave the Deployment Manager running.
- cd Installation Manager directory. The default location is:
- AIX or Linux: /opt/IBM/InstallationManager/eclipse
- Windows: c:\IBM\Installation Manager\eclipse
- Run to start Installation Manager:
./IBMIM --launcher.ini silent-install.ini -input connections_root/silentResponseFile/rollback_file.rsp -log ./rollback.log
where rollback_file is the name of your response file. The default rollback response file is lc_rollback.rsp.
- When the installation is complete, restart the clusters and node agents and synchronize the nodes.
Results
Check the rollback.log file for errors and repeat this task if necessary.
