How to manually remove a corrupted agent installation (brute-force uninstall).

Here are the steps to do the manual brute-force uninstall of the agents:

MONITORED HOST - UNIX

1) Shut down the agent:
a) cd <install_dir>/agents/bin
b) ./quest_launcher_daemon stop
2) Remove the <install_dir>/agents/ directory.

MONITORED HOST - WINDOWS

1) Shut down the agent by stopping the QAM Launcher service.
2) Unregister the service:
a) Open a command prompt
b) cd to <install_dir>/agents/bin
c) run "quest_launcher.exe 3566 -unregister"
d) exit command prompt
3) Remove the <install_dir>/agents/ directory.

If it is a single-tier install, you are done. If you have a separate middleware server, see below.

MIDDLEWARE

If you are not monitoring any other servers and want to completely remove the middleware, you can repeat the above steps on the middleware. However, if your middleware is being used by other collector agents, you will want to follow the below instructions instead:

MIDDLEWARE HOST - UNIX

1) Stop the middleware agent:
a) cd <install_dir>/agents/bin
b) ./quest_launcher_daemon stop

2) Remove or rename the HOST-INSTANCE config directory for the agent you are uninstalling, where HOST is the monitored hostname and INSTANCE is the instance name:
a) cd <install_dir>/agents/SC_DB2/7.0/
b) mv HOST-INSTANCE HOST-INSTANCE.backup
or
rm -rf HOST-INSTANCE

3) Remove or rename the HOST-INSTANCE data directory for the agent you are uninstalling, where HOST is the monitored hostname and INSTANCE is the instance name:
a) cd <install_dir>/agents/SC_DB2/data/
b) mv HOST-INSTANCE HOST-INSTANCE.backup
or
rm -rf HOST-INSTANCE

4) Restart the middleware agent:
a) cd <install_dir>/agents/bin
b) ./quest_launcher_daemon start

MIDDLEWARE HOST - WINDOWS

1) Stop the "QAM Launcher 3566" service.
2) Navigate to <install_dir>\agents\SC_DB2\7.0\ directory.
3) Remove or rename the HOST-INSTANCE directory where HOST is the monitored hostname and INSTANCE is the instance name.
4) Navigate to <install_dir>\agents\SC_DB2\data\ directory.
5) Remove or rename the HOST-INSTANCE directory where HOST is the monitored hostname and INSTANCE is the instance name.
6) Restart "QAM Launcher 3566" service.
