Installing agents in silent mode#
In silent mode, you specify the installation properties in a text file and then run the installation without command-line prompts.
- For production environments, create a user account that is dedicated to running the agent on the computer where the agent is installed.
- Ensure that each computer where you are installing an agent has a supported version of the Java™ Runtime Environment (JRE) or Java developer kit.
- Set the JAVA_HOME system variable to the location of the JRE or JDK that you are using.
- Make sure that your networks and firewalls allow communication on the required ports. See Firewall and communication configuration.
- Ensure that there is no limit on the maximum memory size and virtual memory size. For example, on most Linux™ systems, you can run the
ulimit -m
andulimit -v
commands and ensure that both return the valueunlimited
. To find out how to remove the limit on the maximum memory size and virtual memory size, see the documentation for the operating system.
You specify the installation properties in a properties file. The example.agent.install.properties file is provided as an example of a properties file. The example.agent.install.properties file is in the ucd-agent.zip archive.
-
Copy the following file from the HCL™ Launch server to the target system: installation_folder/opt/tomcat/webapps/ROOT/tools/ucd-agent.zip.
-
Extract the ucd-agent.zip archive file.
-
Open the example.agent.install.properties file for editing, or copy the example.agent.install.properties file to a new properties file.
-
Customize the installation by editing the properties file.
If you do not specify a property, the default value is used. Some properties in the example file are commented out by default. For a list of these properties, see Agent installation properties.
-
Save the file.
-
Run the installation file with the install-agent-from-file.bat command on Windows™ or the ./install-agent-from-file.sh command on Linux. Provide the properties file as a command-line argument.
On Windows, if the properties file is named install.properties, type the following command:
install-agent-from-file install.properties
The installation program installs the agent.
Upgraded or installed agents are migrated to compact mode. Note that agents are updated to compact only if the agent is installed/upgraded on a platform that supports compact agents.
Start the agent. See Starting agents.
