Applying or Rolling back Fixpacks on IBM WebSphere Application Server 8.5.5 (using imcl)

Here, we will learn how to install fixpacks on IBM WAS.

Installed Version : 8.5.0.0

Available Fixpack version : 10 (8.5.5.10)

Please perform below steps to install fixpacks.

1) Stop all the WAS Services
2) Take the backup of all profiles using backupConfig.sh from each profile

    ./backupConfig.sh

3) Check the available package/offering ID from the repository using below command :
  
   $InstallationMgr_Path/eclipse/tools/imcl listAvailablePackages -repositories <Fixpack_repository>

4) Install fixpack using below command :

   $InstallationMgr_Path/eclipse/tools/imcl -s install <Offering_ID> -repositories <Fixpack_repository> -installationDirectory <WAS_install_dir> -acceptLicense -sP

5) Verify the installation using versionInfo.sh

 

We have now updated Fixpack version to 10.

Now we will learn to rollback the fixpack to previous version. In this case, we will remove the fixpack 10 and roll it back to previous version 8.5.5.0. To achieve this, we will use below steps.

1) Get the package/offering ID from the fixpack repository.

 

./imcl listAvailablePackages -repositories <Fixpack_repository_path>

2) Rollback to previous version using below command.

./imcl rollback <previous_version_offering_id>  -repositories <previous_version_repository_path> -installationDirectory <WAS_install_dir> -acceptLicense -sP

3) Verify the installation using versionInfo.sh

Now we have rolled back the fixpack from 8.5.5.10 to 8.5.0.0
