Scope

  • The Agent Batch Installer provides a solution:
    • for installing and updating JobScheduler Universal Agents.
    • which allows the installation or update of any number of Agents on multiple servers. 
  • The Agent Batch Installer applies only for installing Agents on UNIX systems due to the following reasons:
    • In this solution, the JobScheduler Master transfers the needed files to the Agent servers using SSH 
      • Windows standard installations do not come with an SSH client and that would mean installing extra software just for the Agent Batch Installer.
      • This applies for the Agent servers, even though the JobScheduler Master can run on a Windows machine. 
    • Most Windows administrators work with other more complex tools to deploy software on Windows machines (deployment tools such as SSCM), whereas for UNIX the deployment tools are not that complex and it makes sense to offer such a tool.

Use Cases

The following articles describe a number of use cases regarding the installation and update of JobScheduler Agents and how to use the Agent Batch Installer solution in each case:

Excerpt
  • Batch Installation - Use Cases - Homogeneous environment: We define a homogeneous environment as one in which a number of JobScheduler Agents will be installed according to the same prerequisites:
    • A JobScheduler Master is up and running.
    • The Agent installations are to be performed on any number of servers that have the same operating system. One Agent is to be installed per server.
    • The Agents will be operated with the same user, listening port and installation path.
  • Batch Installation - Use Cases - Heterogeneous environment: We define a heterogeneous environment as one in which a number of JobScheduler Agents will be installed according to different prerequisites:
    • A JobScheduler Master is up and running.
    • The Agent installations are to be performed on any number of servers that are not required to have the same operating system. One Agent is to be installed per server.
    • The Agents will be operated with different accounts, listening ports and installation paths.
  • Batch Installation - Use Cases - Multiple Instances: A number of JobScheduler Agents will be installed on each server and each installation will be based on different prerequisites:
    • A JobScheduler Master is up and running.
    • The Agent installations are to be performed on any number of servers that are not required to have the same operating system. More than one Agent is to be installed per server.
    • On every Agent server the Agents will be operated with different accounts and different listening ports.
      • The Agents will be operated with different accounts (within the same Agent server) to make the example more multifaceted, although the same user can operate more than one Agent if the Agents run on different ports.
    • The installation path will be the same for all Agent installations.
