Prepare a Response File for Re-use

Setting up a response file minimizes installation time when installing many agents. You do not have to type in each parameter manually for each installation. For example, if you want to install an agent on 1000 systems, you can automate the process by reusing the first response file you create as a template.

When you create a new agent user account on a target server, keeping the same name and password specified in the response file may offer an advantage. When the account credentials match the response file, you can reuse it without change, because the agent registers with the same CA User Activity Reporting Module server. This means that the authentication key does not change.

To prepare to reuse the response file

1. Log into the Linux server where you created the response file.
2. Navigate to the directory where the original response file resides.
3. Copy the response file and give it a different name.
4. Log into a different Linux system.
5. Create a user account for the agent.
6. Copy the modified response file from the first server to the desired directory on the target agent host.
7. Edit the file to customize it for your requirements. Examples of the data in the response file that you can modify includes the following:
   • Change the installation directory path:

     INSTALL_DIR=/opt/CA/ELMAgent

   • Change the path of the default connectors, if any:

     DEFAULT_CONNECTORS=/temp/connectors.xml

   • Change the IP address of the CA User Activity Reporting Module server:

     ELM_SERVER=127.00.0.29

   • Change the agent authentication key:

     AGENT_AUTHKEY=agent authentication key text

   • Change the User account credentials for the agent:

     AGENT_USER=root
