Uninstalling the Tivoli Workload Scheduler for z/OS Agent using the twsinst script

Follow these steps to uninstall the Tivoli Workload Scheduler for z/OS Agent using the twsinst script. Only agents installed using twsinst can be uninstalled using twsinst. |Depending on the operating system, proceed as follows:

On UNIX, Linux, and IBM i operating systems: |
1. Ensure that all processes and services are stopped, and that there |are no active or pending jobs. For information about stopping the |processes and services, see Tivoli Workload Scheduler: Administration Guide.
2. Log on as root and change your directory to /installation_dir/TWS |(for example: /home/user1/TWS where user1 is the name of Tivoli® Workload Scheduler user.)
3. From the TWS directory, run the twsinst script as follows: |
```
twsinst -uninst -uname username [-wait minutes]
|[-lang lang_id]       
```
|
The uninstall is performed in the language of the locale and |not the language set during the installation phase. If you want to |uninstall agents in a language other than the locale of the computer, |run the twsinst script from the /installation_dir/TWS |(for example, /home/user1/TWS) as follows:
|
```
./twsinst -uninst -uname user_name -lang language
```
where language is the language set during the uninstallation.

On Windows operating |systems: |
1. Ensure that all Tivoli Workload Scheduler processes and services are stopped, and |that there are no active or pending jobs.
2. Log on as administrator on the workstation where you want to uninstall |the product.
3. From the installation_dir\TWS (for example, |c:\Program Files\IBM\TWA), run the twsinst script |as follows: |
```
twsinst -uninst -uname username [-wait minutes]
|[-domain domain_name] [-lang lang_id]   
```
  |
  |
  Note:
  |
  twsinst for Windows is a Visual Basic Script (VBS) that you can |run in CScript and WScript mode.
|
The uninstallation is performed in the language of the locale |and not the language set during the installation phase. If you want |to uninstall agents in a language other than the locale of the computer, |run the twsinst script from the /installation_dir/TWS |(for example, /home/user1/TWS) as follows:
|
```
twsinst -uninst -uname user_name -lang language
```
where language is the language set during the uninstallation.

-uninst: Uninstalls the agent |
-uname username: The name of the user for which the agent is uninstalled. This |user name is not to be confused with the user performing the installation |logged on as root on UNIX and Linux, |as administrator on Windows, and as QSECOFR on IBM i. |
-wait minutes: The number of minutes that the product waits for jobs that are |running to complete before starting the uninstallation. If the jobs |do not complete during this interval the uninstallation stops and |an error message is displayed. Valid values are integers or -1 for the product to wait indefinitely. The default |is 60. |
-domain domain_name: Windows only. The domain |name of the Tivoli Workload |Scheduler user. The default is the name of the workstation on which |you are uninstalling the product. |
-lang lang_id: The language in which the twsinst messages are displayed. |If not specified, the system LANG is used. If the related catalog |is missing, the default C language catalog is used. |
|
Note:
|
The -lang option is not to be confused with the Tivoli Workload Scheduler supported |language packs.
|

The following is an example of a twsinst script |that uninstalls the Tivoli Workload Scheduler agent, originally installed for user named twsuser:

On UNIX, Linux, and IBM i operating systems:

|| |

./twsinst -uninst -uname TWS_user

On Windows operating |systems:

|| |

twsinst -uninst -uname TWS_user
