Introduction

The JobScheduler Universal Agent Batch Installer is a set of files used together by a JobScheduler Master to install the Universal Agent on local and remote servers.

This article describes the use of is one of a series describing how to configure the JobScheduler Universal Agent Batch Installer in a homogeneous environment. We define a homogeneous environment as one in which so that a number of JobScheduler Universal Agents will can 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.

The Batch Installer supports:

First Installation: an Agent has not yet been installed on the server.
Update Installation: an Agent has already been installed and may be up and running.

...

readily installed on a number of servers.

Article Scope

This article describes how to use the Universal Agent Batch Installer to install Agents in a homogeneous environment. Other use cases in this series of articles are listed in the introductory JobScheduler Universal Agent - Batch Installation and Update of Agents article.

A general introduction to installation of the JobScheduler Universal Agent can be found in the JobScheduler Universal Agent - Installation & Operation article.

The JobScheduler Universal Agent - Batch Installation and Update of Agents article provides an overview of how the Batch Installer works. New users are strongly recommended to read this article before proceeding with the instructions presented here.

The Batch Installation - Reference Documentation article provides a detailed guide to configuration of the batch installer with, for example, full lists of parameters.

Installation Environment

This article describes the use of the JobScheduler Universal Agent Batch Installer in a homogeneous environment - that is an environment in which a number of JobScheduler Agents will be installed according to the same prerequisites:

Requirements for this use case:
- 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.

Installation Procedure

General requirements:

A JobScheduler Master is up and running.
A Java Run-time Environment in version 1.8 or newer is installed on the system(s) the Agent is to be installed on.
We recommend that you use the SOS XML Editor to manage the configuration files required for the Batch Installer. More information about the installation and use of the XML editor will be provided later in this article.

1. Download and Extract the Batch Installer and Agent Files

...

The JobScheduler Agents will be installed by a JobScheduler Master that:

connects to the Servers that the Agents are to be installed on and
executes the required Agent installations.

The Batch Installer application has two main components - a JobScheduler AgentBatchInstaller job and a JobScheduler universal_agent_installer job chain. In addition, two XML files batch_installer_config_file.xml and yade_agent_batch_installer_settings.xml are needed for the application.

The AgentBatchInstaller job is responsible for creating the JobScheduler orders for the job chain. Each of these orders is named according to the pattern <host>:<port> to convey the host and port of the server where each Agent is to be installed.

The universal_agent_installer job chain has four job nodes configured in series as follows:

...

The individual nodes in the universal_agent_installer job chain have the following functions:

CheckPreRequisite
- Check for the correct Java version.
- Check whether a JobScheduler Universal Agent has already been installed. If so:
  - - shut down the instance if it is running,
    - remove the installation.
Sync: To wait until all prerequisites have been checked and any already installed Agent instances that are running have been shut down.

TransferInstallationSetup: To transfer the installer files to the host
- Before the transfer starts, the preprocessor will use the use the jobscheduler_agent_instance_script.txt template to create a start script for each Agent instance.
- The XML file yade_agent_batch_installer_settings.xml has to be configured and converted to .ini file before the transfer starts. See the YADE configuration file for the file transfer chapter below for instructions on how to configure the YADE configuration file and YADE Settings File for the File Transfer for instructions on how the .ini file should look like.
- The files that will be transfered are specified with the element <globals><transfer><file_spec=".*\.(sh|gz)$">
- This regular expression is used to select the files to be transfered:
  - the JobScheduler Universal Agent installation files: jobscheduler_unix_universal_agent.tar.gz
    the jobscheduler_agent_<port>.sh start script for the instance
  - the installation script: jobscheduler_universal_agent_install.sh
PerformInstall: The installation is started by SSH.
- The installation script will install and start the JobScheduler Universal Agent
- The PerformInstall job post-processing commands will then be executed:
  - These commands are specified using the <installation><postprocessing><command> element.
  - The default configuration for a Linux server will place the Agent start script under /etc/init.d and set up the autostart for JobScheduler Universal Agent (the following example is for a Ubuntu distribution):
    - ```
    echo ${ssh.sudo_password} | sudo -S cp ${install_path}/jobscheduler_agent/bin/jobscheduler_agent_${agent_options.scheduler_http_port}.sh /etc/init.d/jobscheduler_agent_${agent_options.scheduler_http_port}
```
- echo ${ssh.sudo_password} | sudo -S update-rc.d jobscheduler_agent_${agent_options.scheduler_http_port} defaults

...

2. Configure the Transfer of the Universal Agent Installation Files and the Installation of the Agents

2.1 Edit the XML Configuration

...

Configuration

...

files

Configuring complex XML files with a text editor is often a tedious and error-prone and procedure. To get around this, we recommend that you download the use our XML Editor to manage the configuration files required for the Batch Installer. The XML Editor automatically validates configuration files and thereby therefore reduces the possibility of configuration errors. For details about See the Using the XML Editor see the Using the chapter below for more detailed information about using the XML Editor chapter below.

After downloading the XML Editor, extract the contents of the zip file to a convenient folder (an installation routine is not required) and start the sos.xml.editor.exe program.

Use the XML Editor to configure transfer of the Universal Agent installation files:

Open your yade_agent_batch_installer_settings.xml YADE configurationfile, which is located in the config/batch_installer folder and assign the

 XSD schemafollowing schema in the XML Editor:
http://www.sos-berlin.com/schema/yade/YADE_configuration_v1.0.xsd.
 See 
See the YADE profiles for the file transfer chapter below for instructions on how to configure the YADE configuration file.
Use the XML Editor to configure the installation of the Universal Agents:
Open your batch_installer_config_file.xml configuration file in the XML Editor and assign the scheduler_universal_agent_installations.xsd schema: both files are located in the config/batch_installer folder. 
 See 
See the Batch Installer Configuration File chapter below for instructions on how to configure the Batch Installer configuration file.
 Info
title Hints
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.<version>.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.
2.2 Configure the JobScheduler Jobs
Carry out the following once the job and job chain Once the Job and Job Chain have been extracted to the live folder of your JobScheduler Master carry out the following: 
AgentBatchInstallerjob Job: set 
Set the parameter values for the AgentBatchInstaller job in your JobScheduler Master.
Set the installation_definition_file job parameter to the path that points to the Batch Installer configuration file.
3 Installation of the Agents
The Agents can be installed after the XML configuration files and JobScheduler jobs Jobs have been configured. Start a task for the AgentBatchInstaller job as follows:
Open a JobScheduler Operating Center (JOC) browser window for the JobScheduler master.
Go on the "Jobs" Window and open the folder "batch_installer_universal_agent" folder.
Right click on the job to open the context menu.
Select the Start task immediately operation.
This job will create the appropriate Orders for the JobScheduler 
 orders  as explained in the 
 chapter description of the Batch Installer Application.
Example Use Case: Installation of two Agents
The following example describes the installation of two Agents on separate servers. First of all, the YADE configuration files file for the file transfer will be configured (in XML format), then it will then be converted to the YADE settings file format (.ini) and finally the Batch Installer configuration file will be specified.

yade_profile_transfer
YADE Configuration File for File Transfer
We assume that you  have opened the the yade_agent_batch_installer_settings.xml YADE YADE configuration file in the XML Editor and 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 an Agent installation (of only one Agent).
A separate profile in the YADE configuration file is required for each Agent installation. The default profile name is <host>:<port> where:
...
Add a <ProtocolFragments> element and nodes for each host that you want to install the Agent for. The best way to add another <ProtocolFragments> element using the XML Editor is copying the element and pasting it to the parent element - in this case <Fragments>.
Add a <Profile> element and nodes for each host that you want to install the Agent for. The best way to add another <Profile> element using the XML Editor is copying the element and pasting it to the parent element - here <Profiles>.
The default profile_id is <host>:<port>. If you do not use the default then you have to specify the profile name in the Batch Installer configuration file.
An example for the Batch Installer The contents of the YADE configuration file for the installation of two Agents is attached to this page (download: yade_agent_batch_installer_settings.xml) and is shown example is listed in the following code block:

YADE Settings File for File Transfer
Note that the file shown above is in the YADE XML format and that YADE versions 1.11 10 and newer older require a .ini file to perform the transfer that is specified in the <globals><install_path><transfer><settings> element in the Batch Installer configuration file.
We recommended that you use the XML Editor to convert configuration files from XML to the .ini format (see the XML Editor for converting YADE configuration files (XML) into YADE setting files (.ini) section below for more information).
The following example shows as an example a .ini file that has been converted from the XML file above. You can download the example using this link: yade_agent_batch_installer_settings.ini.

Batch Installer Configuration File
We assume that you  have opened the Batch Installer configuration file batch_installer_config_file.xml xmlin the XML Editor and assigned the scheduler_universal_agent_installations.xsd XSD schema. The XML file contains a basic example with recommended values for an Agent installation.
The Batch Installer configuration file contains an <installation> element for each Agent instance. In addition, the <global> element can be used in a homogeneous environment to specify parameters that will be applied to all Agent installations. If a parameter is specified in both the <global> element and in an individual <installation> element then the setting for the individual element will overwrite the global setting.
...
 Info
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 to in sudoers.
These two 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 elements defined in the Batch Installer configuration file can be used for the postprocessing 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.
