Uninstall OpenText Dimensions CM

Introduction

The Dimensions CM installer creates uninstaller files in the directory _uninst_maintlocated one level up from the Dimensions CM root directory. A record of the installed products is also created in the directory /var/opt/serena/inventory. To uninstall Dimensions CM components, you must use these uninstaller files.

Note: It is good administrative practice to regularly back up the files in /var/opt/serena/inventory.

During uninstallation, Java executable files are installed that enable you to run the uninstaller in either GUI mode or "dumb-terminal/VT100" mode. GUI mode is the default, VT100 mode is invoked by specifying "uninstaller.bin -console".

Before initiating the procedures, ensure that you are not running any Dimensions or RDBMS applications.

Stop Tomcat‌

If you are uninstalling a Dimensions CM server first shut down Tomcat:

Log in as the Dimensions system administrator (the user who owns the Dimensions CM files). Default: dmsys

Caution: Do not stop Tomcat as user root. It must be stopped by the DSA to shut down correctly.

Stop the Common Tomcat:

$ cd $installdir/../common/tomcat/<tomcat-version>/bin
$ ./shutdown.sh

To verify that Tomcat is not running check the process list for the tomcat process.

Shut down Dimensions CM‌

If you are uninstalling a Dimensions CM server or agent, first shut down Dimensions CM:

Log in as user root.
Give yourself the Dimensions CM environment variable values by running the appropriate Dimensions CM login script, for example:
- Bourne Shell
```
$ cd /opt/opentext/dimensions/<version>/cm
$ . ./dmprofile
```
- C Shell
```
$ cd /opt/opentext/dimensions/<version>/cm
$ source ./dmlogin
```
Shut down Dimensions CM:
1. Go to the Dimensions CM prog directory, for example:
```
# cd /opt/opentext/dimensions/<version>/cm/prog
```
2. Run this command:
```
# dm_control cm_stop
```
Check that the Dimensions CM processes have shut down:
```
# ps -eaf | grep dm[pal]
```
Services such as dmappsrv.x and dmpool.x should not be listed.

Uninstall components‌

To uninstall Dimensions CM components:

Log in as user root.
Navigate to the _uninstall director located one level up from the Dimensions CM root directory, for example:
```
opt/opentext/dimensions/<version>/_uninst_maint
```

Invoke the uninstaller:

```
For GUI mode:
# ./uninstaller.bin
```

For CUI mode:
```
# ./uninstaller.bin -console
```

Error messages when uninstalling UNIX clients‌
