Uninstalling Pervasive PSQL Vx Server
The uninstall program removes the Pervasive PSQL engine, and all related components from your system that were added by the installation program, including registry settings, configurations and Pervasive PSQL system and sample databases.
The uninstall program does not remove the following:
•
Pervasive PSQL Vx Server keys.
•
Databases that you create under the Pervasive PSQL Vx Server installation directory.
•
DSNs and database names associated with those databases.
•
Databases in locations other than the Pervasive PSQL Vx Server installation directory.
•
Other Pervasive PSQL products such as AuditMaster, Backup Agent, or DataExchange. Such programs have their own uninstall programs. Refer to the documentation for each product.
Uninstalling from Windows
1
Use a license utility (GUI or CLI) to deauthorize the key that was used to authorize Pervasive PSQL Vx Server. This allows you to use the key for a different installation if you so choose. See To Deauthorize a Key in Pervasive PSQL User's Guide, for example.
2
In the Windows Control Panel, select Add/Remove Programs.
3
Select the installed Pervasive PSQL Vx Server product from the list.
4
Click Change then Next.
5
Click Remove then Next and follow any prompts during the uninstall.
If prompted, close or uninstall any running applications that may interfere with uninstalling Pervasive PSQL.
*Caution: Unpredictable results may occur during the uninstall if you ignore programs that may interfere.
Reboot your system, if prompted to do so.
Uninstalling from Linux
The steps for uninstalling from Linux are slightly different for RPM and TAR. In either case, however, the uninstall program does not remove the system databases DEFAULTDB and SYSTEMDB nor the Pervasive PSQL Vx Server keys.
*Note: Before uninstalling, run the command line License Administrator utility to deauthorize the key that was used to authorize Pervasive PSQL Vx Server. This allows you to use the key for a different installation if you so choose. See To Deauthorize a Key in Pervasive PSQL User's Guide.
