Uninstalling in silent mode

The process requires no response file on Windows platforms. On UNIX and Linux you need to customize a response file template with the user credentials of the administrator (TWSuser) of the embedded WebSphere® Application Server that the Tivoli Workload Scheduler for z/OS connector instance is using.

Perform the following steps:

• On Windows, go to drive:\Program Files\IBM\TWA\TWSZOS\_uninstall, and run:

  uninstall.exe -silent

• On UNIX and Linux:
  1. |Copy the TWS86_ZCONN_UNINSTALL_UNIX.txt response |file template located in the responsefiles directory |of the installation DVD to a local directory.
  2. Edit the response file template with the user name and password of the WebSphere Application Server administrator and save it with a different name.
  3. |Go to opt/ibm/TWA/TWSZOS/_uninstall and |run: |

     ./uninstall.bin -options local_dir/TWS86_ZCONN_UNINSTALL_UNIX.txt -silent

  If you want to reinstall after running a silent uninstallation, you must first close and reopen the shell to correctly reset the environment variables.
