Uninstalling Backup Agent on Linux or OS X
This section covers removal of Backup Agent from a Linux or OS X machine.
Caution Removing Backup Agent stops and then restarts PSQL services, so your database is briefly shut down.
Removing the TAR Version on Linux
►
To uninstall a Backup Agent TAR installation on Linux
1
Log in as the root user.
2
Log in as psql or any other user of group pvsw. For user psql, no password is needed.
su - psql
3
Be sure that Backup Agent is turned off by issuing one the following commands:
pvbackup -off
pvbackup64 -off
The command displays the following text:
Backup Agent is now OFF.
4
Exit back to root user.
exit
5
Since the uninstall will remove /usr/local/psql/pba and its subdirectories, be sure the current working directory is located above the Backup Agent home directory. For example, change directories to /usr/local/psql.
cd /usr/local/psql
6
Run the first uninstall script.
sh pba/etc/preuninstall.sh
The system shuts down PSQL, cleans up memory, unregisters Backup Agent libraries, and removes files, logs, links, and configuration settings made by the initial installation.
Backup Agent is now removed from your Linux system.
7
When the first script finishes, run the second uninstall script.
sh pba/etc/postuninstall.sh
The second script removes the Backup Agent directories and restarts PSQL.
Backup Agent is now removed from your Linux system.
8
After installation, you can verify that the database engine is running by using the following command:
/etc/init.d/psql –status
Removing the TAR Version on OS X
►
To uninstall a Backup Agent TAR installation on OS X
You must be logged in as a user with administrator rights to use the sudo command.
1
Open a terminal window by entering terminal in a Spotlight search.
2
At the prompt, enter a sudo command like the following to gain administrative rights to install applications:
sudo -i bash -l
3
Change directories to the /usr/local/psql/etc folder where the Backup Agent installation scripts reside.
cd /usr/local/psql/etc
4
Use the following uninstall scripts:
./preuninstall.sh
./postuninstall.sh
The scripts must be executed in sequence: preuninstall first, followed by postuninstall.
Backup Agent is now removed from your OS X system.
5
After installation, you can verify that the database engine is running by using the following command:
/usr/local/psql/etc/init.d/psql –status
Removing the RPM Version
►
To uninstall using RPM
Caution Removing Backup Agent stops and then restarts PSQL services, so your database is briefly shut down.
1
Log in as the root user.
2
Log in as psql or any other user of group pvsw. For user psql, no password is needed.
su - psql

pvbackup -off
pvbackup64 -off
The command displays the following text:
Backup Agent is now OFF.
4
Exit back to root user.
exit
5
Since the uninstall will remove /usr/local/psql/pba and its subdirectories, change the current directory to another location. For example, change directories to psql home, /usr/local/psql.
cd /usr/local/psql
6
Issue the following command:
rpm -e <PSQL_Backup_Agent_package_name>
The package manager stops PSQL services, removes the /usr/local/psql/pba directory, its subdirectories, and all files, logs, links, and configuration settings made by the initial installation, then restarts PSQL services again.
Backup Agent is now removed from your Linux system.
