Deinstall the Old STA Version (Task 3)

You must deinstall the current version of STA.

Caution:

Uninstalling STA removes all STA data on the server. Make sure you have backed up the database if using the single-server method.

IMPORTANT: For the single-server upgrade method, make sure you have completed Dump the Old STA Database (Task 1) and Transfer the Old Database Dump (Task 2).
On the STA server, open a terminal session. Log in as the Oracle user that is a member of the Oracle group. You cannot deinstall STA as the Linux root user nor any other user with superuser privileges.
Change to the installer binary directory with the STA home directory. For example:
```
$ cd /Oracle/StorageTek_Tape_Analytics/oui/bin
```
Select either the wizard or silent mode to deinstall STA. Use the following commands to launch the deinstallation.
- Wizard:
```
$ ./deinstall.sh
```
  After launching the wizard, see Deinstall Using the Wizard. This mode requires an X11 display. See Installation Wizard Display Requirements for instructions.
- Silent-mode:
  
  Before running silent mode, you must create a response file. See Create a Response File.
```
$ ./deinstall.sh –silent –responseFile <absolute path to responsefile>
```
After completing the wizard or silent-mode deinstaller, verify the deinstallation was successful by listing the contents of the Oracle storage home directory. It should be empty.
For example:
```
$ ls -la /Oracle
total 8
drwxr-xr-x   2 oracle oinstall 4096 Sep 23 14:55 .
dr-xr-xr-x. 31 root   root     4096 Sep 23 16:41 ..
$
```
