Uninstalling fix packs using response files

You can roll back this product to an earlier version using IBM® Installation Manager with a response file.

Before you begin

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.

About this task

Restriction: You cannot use the Installation Manager to roll back an installation and add or remove the full WebSphere® Application Server profile feature or the Liberty profile feature.

Procedure

Optional: If the repository requires a username and password, create a keyring file to access this repository.

For more information on creating a keyring file for Installation Manager, read the IBM Installation Manager Version 1.5 Information Center.

Tip: When creating a keyring 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.

Use a response file to roll back the product.

  -log C:\temp\rollback_log.xml 
  -keyring C:\IM\im.keyring
```
- Administrator:
```
./imcl
  input /var/temp/rollback_response_file.xml 
  -log /var/temp/rollback_log.xml 
  -keyring /var/IM/im.keyring
```
- Non-administrator:
```
./imcl
  input user_home/var/temp/rollback_response_file.xml 
  -log user_home/var/temp/rollback_log.xml

```
Note: The program might write important post-installation instructions to standard output.
