The example described below builds on the example presented in the Batch Installer Installation - Use Case - Multiple Instances article in which a total of four agents were installed on two servers. Note, however, that only one Agent server with a single Agent installed on it is required before the current example can be implemented.

The XML Editor is available for Windows.
YADE is an Open Source file transfer solution for FTP, SFTP, FTPS, WebDAV and other protocols. It is used here for transferring the following files from the JobScheduler Master to the Agent servers:
- JobScheduler Universal Agent installation files: jobscheduler_unix_universal_agent.1<version>.10.2.tar.gz
- Start script for an Agent instance: jobscheduler_agent_<port>.sh
- Installation script: jobscheduler_universal_agent_install.sh
For more information about YADE, see the YADE product site.

...

The following example describes how to do the installation and configuration of a JobScheduler Universal Agent on an Agent Servers, in an environment with four JobScheduler Universal Agents already installed - two Agents on two different servers. The extra instance is added to the configuration already described in the Batch Installer Installation - Use Case - Multiple Instances use case. ´The Batch Installer will ignore the configuration information for the agents that have already been installed as the update job parameter for the AgentBatchInstaller job has been set to false as described in the JobScheduler Jobs section of this article above.

...

The configuration file contains configurations for the four Agents whose installation was described in the Batch Installer Installation - Use Case - Multiple Instances article. The file also contains the configuration for the additional Agent that is to be installed in this example. The configuration for this Agent can easily be recognized by <installation lastRun=""> element tag.

title	Post-processing commands

The SSH login user has to be set to root in order to execute these commands. Therefore the SSH login user should be included in sudoers.
The two post-processing commands will be executed by the PerformInstall job node, which is the last job node in the job chain. If you want to add more commands, please add the call to the job node.
Note that the values for the XML elements defined in the Batch Installer configuration file can be used for
Status

title additional?
post-processing commands, for instance:
- ${install_path}: the value for the element <install_path>
- ${agent_options.scheduler_http_port}: the value for the element <scheduler_http_port>. If not defined, the default value (4445 in this case) is taken, as in the example below.
