Uninstalling Cognos via the graphical user interface wizard

If the Cognos-Metrics installation does not complete properly, you can uninstall the primary BI server, the secondary BI server, and Transformer using the Cognos® installation wizard.

About this task

Since there will be some important information in <Cognos Installation Path>, uninstall only removes cognosBI/ and Transformer/ folders under it. To re-install them just after you finish the uninstallation, manually delete the folder <Cognos Installation Path>.

Procedure

Launch Installation Manager.
```
./imcl -c
```
Select Uninstall.

Choose the Cognos package group for uninstall.

=====> IBM Installation Manager> Uninstall

Select one package group to uninstall from:
       1. [ ] IBM WebSphere Application Server Network Deployment V8.0
       2. [ ] IBM Cognos Wizard

       C. Cancel
-----> [C]

Choose the Cognos package for uninstall.
On the WebSphere Application Server information panel, start the server1 on Cognos node profile to connect to the node and retrieve node information.
Note: No input is needed to remove Transformer. So if you uninstall Transformer, you can do that directly.
After validation completes, click Next to go to next panel.
Click Uninstall, then allow the uninstall process to complete.
After uninstall completes, check the WebSphere Application Server administrative console of the appropriate system to ensure that the following items no longer appear:
- On Deployment Manager, the Cognos application is removed
- On Deployment Manager, there is no Cognos server
- On Deployment Manager, there is no Cognos node
- On Deployment Manager, there is no Cognos cluster
- On the node where Cognos was installed, there is no Cognos application
- On the node where Cognos was installed, there is no Cognos server
- Check whether Metrics-associated scheduled tasks have been removed as follows:
  - On Windows: In Administrative Tools > Task Scheduler, MetricsCubeDailyRefresh and MetricsCubeWeeklyRebuild do not appear in the Active Tasks list.
  - On Unix or Linux: Execute run crontab -l. You should not see either Cognos_Transformer_install_path/metricsmodel/daily-refresh.sh or Cognos_Transformer_install_path/metricsmodel/weekly-rebuild.sh.
