Simplified z/OS Installation Method

This document describes a simplified installation method for EntireX under z/OS. It is an alternative to the installation method described in subsequent sections. This document covers the following topics:


Overview

The simplified installation requires the following steps:

  1. Set the installation keyword parameters in a parameter member.

  2. Execute a REXX script that updates the delivered installation jobs with the values of that parameter member.

  3. Auto-submit the updated jobs if requested in the parameter file, or make them ready for a manual submission.

Delivered Members

The delivered members in the original EXX103.JOBS data set are:

#IPARMS

The installation parameters.

#RX#CMD

The REXX update script.

#RX#JOB

A job to execute #RX#CMD in batch.

#INSTALL

Generated on first submission: Documents the installation jobs required as a result of the components selected.

Note:
Only the #INSTALL job will be copied to the target .JOBS data set. The first three members remain in the original EXX103.JOBS data set.

#IPARMS - The Parameters

This member keeps all parameters relevant for installation and is located and maintained in the delivered data set EXX103.JOBS only, which was copied directly from the installation medium. To avoid a complete setup, you can select an already maintained #IPARMS. See #RX#JOB - A REXX Batch Job.

Member Layout

The parameter member contains the following sections:

  1. global installation parameters

  2. job card related parameters

  3. installable unit subproduct selection parameters

  4. installable unit installation parameters

  5. data set names / high-level qualifiers

  6. VSAM file characteristics

Parameter Line Layout

A parameter member line has the following layout:

* ----------------------------------------------------------------- *
* JOBCARD
* ----------------------------------------------------------------- *
  keyword   = value           * comment
where keyword is a placeholder for a keyword
= is the value separator
value is the keyword value
* introduces a comment. A line that begins with an asterisk in column 0 is treated as a comment line.

#RX#CMD - The REXX Script

This script copies all the necessary jobs from the original EXX103.JOBS data set of the delivered installation medium to a selected installation target.JOBS data set. All placeholders in the original jobs will be replaced with the values set in the parameter member. An existing target.JOBS data set of a previous generation will be saved in a GDG data set first.

A #INSTALL member will be created for documentation and to distinguish between the jobs required as a result of the selected components and the optional installation jobs. All required installation jobs can be submitted directly with this member.

#RX#JOB - A REXX Batch Job

Calls the #RX#CMD REXX script from batch.

The #RX#CMD script expects six KEYWORD parameters that need to be maintained and set to suitable values in the #RX#JOB first. There are two groups of keyword parameters: mandatory and optional.

  • Mandatory Keyword Parameters
    • ORIG - The name of the EXX103.JOBS data set copied from the installation medium

    • INST - The name of the target.JOBS data set that will contain the generated installation jobs

  • Optional Keyword Parameters
    • PARM - The name of a data set containing an already maintained #IPARMS member. If a #IPARMS member is found here it will be selected for the installation jobs generation process.

    • MSGS - Switch IEBCOPY sysout messages on or off. Possible values are:
      Y - Show IEBCOPY sysout (default)
      N - Hide IEBCOPY sysout

    • INST_SMS - Switch SMS control on or off for the target.JOBS data set named with the mandatory INST keyword parameter. Possible values:
      Y - Switch ON the SMS controlled allocation of the installation jobs data set
      N - Switch OFF the SMS controlled allocation of the installation jobs data set

    • INST_VOL - Contains the SMS class name or the VOLSER name depending on the value of keyword parameter INST_SMS
      INST_SMS=Y - The SMS class name
      INST_SMS=N - The DASD VOLSER name

Important:
It is mandatory to edit this job manually before submission to define at least the mandatory keywords naming the input (EXX103.JOBS) and output (target.JOBS) data sets.

#INSTALL - Document the Required Installation Jobs (Depending on Selected Components)

This member will be generated in both, the EXX103.JOBS and the target.JOBS data sets. It has two functions:

  1. Documentation of the Installation Jobs Required as a Result of the Selected Installable Units
    Each required installation job is represented here with a separate line headed by its member name in the EXX103.JOBS.

  2. Submission of the Required Installation Jobs
    As this member is a job itself, it can be submitted to submit all the required installation jobs. You can also select a subset of jobs for submission by (un)commenting their execution lines.

Installation Jobs

All existing jobs remain unchanged in the original EXX103.JOBS data set. Only the jobs necessary for the installation of the selected installable units will be copied to and updated within the designated target.JOBS data set by the #RX#CMD REXX script.

Note:
This update process is not mandatory. All jobs can still be manually adapted as before. But to be able to successfully execute the installation script afterwards, the original EXX103.JOBS data set should be kept unchanged.

This section covers the following topics:

Generation Data Sets

After a successful generation, the following data sets are in the system:

  • EXX103.JOBS
    The delivered product data set. The members of this data set will remain unchanged with the exception of the #IPARMS parameters and possibly the #RX#JOB.

  • target.JOBS
    The target data set which will contain the selected and updated jobs from the EXX103.JOBS data set.

  • target.JOBS.BAK
    A VSAM GDG base catalog entry for the GDG data sets.

  • target.JOBS.GnnnnVnn
    With any subsequent generation, all jobs of the previous generation in the target.JOBS data set are kept here until the maximum value set in the MAXBACKUPS parameter (to be found in #IPARMS) is reached.

Preparation and Execution

Start of instruction setTo prepare and install the installation jobs

  1. Update the EXX103.JOBS (#IPARMS) parameter member.

  2. Submit the job EXX103.JOBS(#RX#JOB) to execute the REXX script #RX#CMD.

Generation Process

Every keyword parameter has a well defined default value. This default will be replaced only if requested by the parameter member, that is, if a KEYWORD=VALUE entry is successfully identified. When a keyword is deleted from the parameter member (or commented out), this default will always be in place.

Submission

Start of instruction setTo submit the installation jobs

  • In the #IPARMS member select the switch SUBMIT.

    • If set to "Y":

      Any job is submitted with a TYPRUN=HOLD job card parameter.

      Note:
      This allows a final check to ensure a correct generation. Any job can then be released manually one after the other in the numbered order or can be cancelled if an error was encountered.

      If you cannot issue the JES release command for security reasons, you can submit using the generated #INSTALL job in the target.JOBS instead.

    • If set to "N":

      The TYPRUN=HOLD job card parameter is set to comment and no job is submitted at all.

Note:
The #INSTALL member will be generated regardless of the SUBMIT parameter value.

Installation Verification

Installation verification is the same for both installation methods. See Verifying the z/OS Installation.

Administration Tasks

After installation has been completed, various administration tasks may be necessary.

Modify Broker Attribute File

Customize the attribute settings to suit your needs. See Broker Attributes.

Set up Broker Stubs

See Administering Broker Stubs.

Define the Persistent Store

A persistent store can be optionally used for storing unit of work messages and message status information to disk. For z/OS, you can use an Adabas persistent store (recommended) or a DIV persistent store that uses a VSAM linear data set.

Adabas Persistent Store

See Implementing an Adabas Database as Persistent Store and Adabas-specific Attributes in the Broker attribute file documentation for more information.

DIV Persistent Store

See Implementing a DIV Persistent Store under Managing the Broker Persistent Store and DIV-specific Attributes for more information.

Setting up the EntireX RPC Servers

See RPC Server for CICS, RPC Server for Batch or RPC Server for IMS for more information.
