Installing the Agent › Reinstall the Agent

Reinstall the Agent

If you receive a new version of the agent or if the agent files are purged or get corrupted, you can reinstall the agent using the interactive program.

When you reinstall CA WA Agent for HP Integrity NonStop, the interactive program prompts you for additional information.

To reinstall CA WA Agent for HP Integrity NonStop

1. Log in as SUPER.SUPER.
2. Download the CAWAPAK installation package to the location from which the agent is to be installed. This may be a temporary local drive and not where you plan to actually install the agent.
3. Decompress the installation package using the following command:

   UNPAK CAWAPAK,*.*.*,VOL volume_name
   

   volume_name

   Specifies the volume where the agent is to be installed.

4. Go to the CARELSCR subvolume. For example, type “volume volume_name.CARELSCR”.

   CARELSCR is the subvolume where the files are placed after the execution.

5. Type the following command to start the installation:

   RUN CASETUP
   

   The agent installation program opens.

6. Continue with the reinstallation by entering the required information.
