You can roll back WebSphere® Application Server Liberty Core to an earlier version using the Installation Manager command
line.
Before you begin
You must have IBM® Installation Manager Version 1.8.5 or later installed on your
system.
During the rollback process, Installation Manager must access files from the earlier version of
the package. By default, these files are stored on your computer when you install a package. If you
change the default setting or delete the saved files, Installation Manager requires access to the
repository that was used to install the earlier version.
Procedure
- Optional: If the repository requires a username
and password, create a credential-storage file to access this repository.
Tip: When creating a credential-storage file, append /repository.config at the end of the repository URL location
if the imutilsc command is unable to find the URL
that is specified.
- Sign on to the IBM i system with a user profile that has *ALLOBJ and *SECADM special
authorities.
- Stop all servers and applications on the installation that
is being rolled back.
- On a CL command line, run the STRQSH command to start the Qshell command shell.
- Change to the eclipse/tools subdirectory
in the directory where you installed Installation Manager.
- Use the imcl command to roll back the
product.
