To Uninstall Completely

1. Stop the Application Server processes using these commands:

   asadmin stop-cluster FirstCluster

   asadmin remove-ha-cluster --hosts hadb-hostname,hadb-hostname FirstCluster

   Replace the hadb-hostname variable with the host name of the machine where HADB is to run. If you are using just one machine, you must name it twice.

   asadmin stop-node-agent hostname

   asadmin stop-domain domain1

2. Stop the HADB Management Agent by one of the following methods:

   • In a Solaris or Linux Java Enterprise System installation:

     1. Change to the /etc/init.d directory:

        cd /etc/init.d

     2. Run the command to stop the agent:

        ./ma-initd stop

   • In a Windows Java Enterprise System installation:

     1. Go to Start⇒Settings⇒Control Panel, and double-click Administrative Tools.

     2. Double-click the Services shortcut.

     3. Select HADBMgmtAgent Service from the Services list.

     4. From the Action menu, select Stop.

   • In a stand-alone Solaris or Linux Application Server installation:

     1. Change to install-dir/hadb/4/bin.

     2. Run the command to stop the agent:

        ./ma-initd stop

   • In a stand-alone Windows Application Server Installation:

     1. Change to install-dir\hadb\4.x\bin.

        The x represents the release number of HADB.

     2. Run the command to stop the agent:

        ma.exe -r

   At this point, all processes related to Sun Java System Application Server are stopped.

3. Uninstall the Application Server.

   • In a Solaris or Linux Java Enterprise System installation, run var/sadm/prod/entsys/uninstall and follow the steps in the uninstallation wizard.

   • In a Windows Java Enterprise System installation, use the Control Panel's Add/Remove Programs item. Choose Sun Java Enterprise Systems and click Change/Remove. Remove install-dir\bin from the PATH environment variable and delete the AS_ADMIN_USER variable.

   • In a Solaris or Linux standalone Application Server installation, run install-dir/uninstall and follow the steps in the uninstallation wizard.

   • In a Windows standalone Application Server instance, from the Start menu, choose Programs ⇒ Sun Microsystems ⇒ Application Server EE ⇒ Uninstall.
