You can roll back WebSphere® Application
Server Liberty Core to an earlier version using the Installation Manager command
line.
Before you begin
Restriction: In order to use this procedure, you must have Installation Manager Version
1.6 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.
Note: When you use Installation Manager Version 1.6.2 and later, you should use the
-secureStorageFile and
-masterPasswordFile options to
store credentials in a credential-storage file. In versions of Installation Manager earlier than
Version 1.6.2, the
-keyring and
-password options were
used to access credentials in a keyring file. These options were deprecated in Version 1.6.2. There
is no migration path from keyring files to storage files because of the differences in the file
structures. For more information on using the
-secureStorageFile and
-masterPasswordFile options to store credentials in a credential-storage file,
see the
Installation Manager Version 1.6 documentation. For more information on
using the
-keyring and
-password options to store
credentials in a keyring file, see the
Installation Manager Version 1.5 documentation.
- 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.
