Environment

This article describes the use of the JobScheduler Universal Agent Batch Installer for installing additional JobScheduler Universal Agents in an environment in which a number of the Agents have already been installed. The environment can be summarized as having the following characteristics:

  • A JobScheduler Master is up and running.
  • JobScheduler Agents have already been installed on different Agent servers.
  • Another Agent is to be installed.
  • The new Agent will be operated with same user and installation path as for the rest of the Agents installed on this Agent server.
  • The listening port for the new Agent will be obviously a different one than the installed Agents on this server.

Prerequisites

In case you an extra Agent installation has to be done, that would mean that other Agents have been installed (either using the Batch Installer or through other methods). In any case, to understand properly how this application works in case you had not use the Batch Installer for Agents before, you can find the relevant information for your corresponding environment in the articles described below - have a look at the chapters "Batch Installer Application" and "Download":

  • Batch Installer Use Case: Homogeneous environment: This article describes the use of the JobScheduler Universal Agent Batch Installer in a 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 Installer Use Case: Heterogeneous environments: This article describes the use of the JobScheduler Universal Agent Batch Installer in a 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 do not have to have the same operating system. One Agent is to be installed per server.
    • The Agents will be operated with different users, listening ports and installation paths.
  • Batch Installer Use Case: Multiple Instances: This article describes the use of the JobScheduler Universal Agent Batch Installer for installing multiple Agent instances in a heterogeneous environment. A multiple number of JobScheduler Agents will be installed on every Agent server and every 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 do not have to have the same operating system. More than one Agent is to be installed per server.
    • In every Agent server, the Agents will be operated with different users and different listening ports.
      • The Agents will be operated with different users (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.

Configuration

XML files

Configuring XML files with a text editor is error-prone and we recommend that you download the XML Editor and use it to manage the configuration files required for the Batch Installer. The XML Editor automatically validates configuration files and therefore reduces the possibility of configuration errors. See the Using the XML Editor chapter below for more detailed information about the XML Editor.

...

Info
titleHints
  • The  XML Editor is available for Windows.
  • YADE is an Open Source file transfer solution for FTP, SFTP, FTPS, WebDAV and other protocols. Concretely, it will be used here for transferring the following files from the JobScheduler Master to the Agent servers:
    • JobScheduler Universal Agent installation files: jobscheduler_unix_universal_agent.1.11.0-SNAPSHOT.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.

JobScheduler Jobs

Carry out the following once the job and job chain have been extracted to the live folder of your JobScheduler Master: 

  • AgentBatchInstaller job: adjust the parameter values for the AgentBatchInstaller job in your JobScheduler Master.

    • Set the installation_definition_file job parameter to the path to the Batch Installer configuration file.

    • Set the update job parameter to false. This value set to false is the one that will determine that the rest of the installations defined in the configuration for Batch Installer Configuration File are not going to be performed.

Installation of the Agents

The Agents can be installed after the XML configuration files and JobScheduler jobs have been configured. Start a task for the AgentBatchInstaller job as follows:

  1. Open a JobScheduler Operating Center (JOC) browser window for the JobScheduler master.
  2. Go on the "Jobs" Window and open the "batch_installer_universal_agent" folder.
  3. Right click on the job to open the context menu.
  4. Select the Start task immediately operation.

Example: Installation of one extra JobScheduler Universal Agent

The following example describes how to do the installation and configuration of one JobScheduler Universal Agents in one of the Agent Servers, where exactly four JobScheduler Universal Agents had already been installed - two Agents on two different servers. The extra instance is added to the configuration described in the Use Case above: Batch Installer Use Case: Multiple Instances.

YADE Configuration File for File Transfer

We assume that you  have opened the yade_agent_batch_installer_settings.xml YADE configuration file and have assigned the http://www.sos-berlin.com/schema/yade/YADE_configuration_v1.0.xsd XSD schema. The XML file contains a basic example with recommended values for the installation of a single Agent.
