IBM Mainframe Production Acceptance - Batch Jobs

SO-04-003 IBM Mainframe Production Acceptance – Batch Jobs

Issue Date:  8/08/2003

Revision Effective Date:  8/08/2003

PURPOSE

The purpose of this standard is to establish batch job production acceptance standards to guarantee that service levels are met for all IBM Mainframe applications.

SCOPE

The scope of this standard applies to all GTA-ITIS managed computer facilities in all affected Georgia state agencies.

STANDARD

Change Man Planned Package Standards:

•        All production jobs must go through production acceptance as a Change Man Planned Package in Change Man.

•        Change Man Planned Packages must pass a quality assurance review and receive approval by GTA-ITIS Operations.

•        Planned Change Man Packages are accepted by GTA-ITIS Operations from 6:00 A.M. to 6:00 P.M. for review and approval/rejection on the same business day.

•        Include three (3) hours for install date and time to allow GTA-ITIS Operations enough lead time to review the Change Man Planned Package. Packages received after

6:00 P.M. will be processed the next business day.

Naming Convention Standards:

 

•        The batch Job name shall conform to the standard naming conventions for all new batch jobs as outlined in Doc Ref Number: OP_STD_001.

•        The Member name must have the same name as the batch job name.

 

Batch Job Class Standards:

 

The Production batch job must have the correct job class assigned. The following is a list of the available batch job classes and their criteria:

 

Batch Job Classes

Class D, System A - Tapes allowed with 10 minute time limit

Class E, System B – Maximum of 2 concurrent tape drives

Class F, System B – Greater than 2 concurrent tape drives

Class H, System A – Maximum of 2 concurrent tape drives

Class I, System A – Greater than 2 concurrent tape drives

Class P, System A – No tapes / 10 minute time limit

Class R, System A – No tapes /Longer than 10 minutes

Class Y, System B – No tapes

** Classes I and F are special classes.  The criteria and business justification for assigning I & F must be included in the Change Man documentation.

JCL Batch Job Card Standards:

  • Include a valid Department Number as the first three (3) digits in the Account Number.
  • Use the programmer name field to identify the location or group to send the output.  This parameter contains the following:
    • A maximum of 20 characters.
    • Enclose the name with apostrophes if the name contains spaces, special characters other than hyphens, embedded periods, or leading periods.
  • Use one of the appropriate Batch Job Classes listed in the “Batch Job Classes” table in this document.
  • The MSGCLASS parameter must equal M if the batch job goes to $AVRS.
  • If you specify a time parameter, the following are not permitted:

          TIME=NOLIMIT               TIME=MAXIMUM             TIME=1440

  • The job card cannot have TYPRUN=HOLD

For example:

 //HRPH0001 JOB 427PV400, ‘PROD 15PTREE’, CLASS=F,MSGCLASS=M, TIME=240

Where:

HRPH0001 is the job name

427 is the Department Number

PV400 is the Account Number

‘PROD15PTREE’ is the Programmer’s Name

TIME=240 is the Time Limit

 

JCL and PROCS Standards:

 

•        PROCLIB overrides are NOT allowed in production.

Examples: Highlighted key words are not allowed

//PROCLIB JCLLIB ORDER =(PSDP.DBT1.PROCLIB)

or

/*JOBPARM L=10,P=TESTPROC

•        SHARED production libraries must have a DISPosition equal to share (SHR).

                   Example: CHNM.PROD.LOADLIB,DISP=SHR

•        SHARED production libraries must begin with the following characters:

•        CHNM.PROD.*

•        CHNM.PRODRT.*

•        SYS1.*

•        SGDP.*

•        #SGDP.*

•        SGSS.*

 

•        JOBLIB and STEPLIB statements must contain load libraries that represent

          SHARED production or system libraries, NOT user controlled libr

          CORRECT EXAMPLE                                              

//JOBLIB DD DSN=SGDP.DBP5.DSNEXIT,                       
//            DISP=SHR                                                      
//          DD DSN=SGDP.DBP5.DSNLOAD,                        
//            DISP=SHR                                                      
//          DD DSN=CHNM.PROD.TEMP.LOADLIB,                
//            DISP=SHR                                                      
//          DD DSN=CHNM.PROD.LOADLIB,                         
//            DISP=SHR                                                      
 

INCORRECT EXAMPLE

//JOBLIB DD DSN=SGDP.DBP5.DSNEXIT,

//            DISP=SHR

//          DD DSN=SGDP.DBP5.DSNLOAD,    

//            DISP=SHR

//          DD DSN=HRBT.LOADLIB,---- Incorrect

//            DISP=SHR

//          DD DSN=CHNM.PROD.LOADLIB,

//            DISP=SHR

 

•        Apply the following guidelines if you use a continuation card:

•        Include a comma (,) at the end of the card to be continued.

•        Do not start a continuation after column 16.

For example:

//STEP1 DD DSN=XXXX.XXXX.XXXX,
// DISP=SHR
 

•        Make sure there is no // CARD or PEND card at the end of PROC.

•        Apply the following guidelines if the batch job requires user-defined variables or other input parameters:

•        The JCL cannot have a SYSIN DD * card. This card must point to a production utilcard library.

For example:

CHNM.PRODRT.UTILCARD or CHNM.PROD.UTILCARD

Where:

CHNM.PRODRT.UTILCARD is used by the Department of Revenue, and

CHNM.PROD.UTILCARD applies to all other agencies

•        The symbolic library and member referenced by the %%LIBSYM and %%MEMSYM must be valid.

For example:

//* %%LIBSYM HRHP.PROD.REQUEST.USER %%MEMSYM HRPHABSV

//HRPHABSV EXEC HRPHABSV,YEAR=%%CCYY

THE PARAMETER, YEAR=%%CCYY, IS FOUND IN THE LIBSYM LIBRARY IN THE MEMBER, MEMSYM

•        Use the following classes to specify SYSOUT:

SYSOUT=X            Xerox print output

SYSOUT=A            Print output for continuous feed, standard paper

SYSOUT=C            All multi-part paper, for example: 0002, 0003

SYSOUT=J             Special forms (user supplied), for example: labels

SYSOUT=M            $AVRS

SYSOUT=R            Infopac

SYSOUT=*            Allowed only in the JCL.  Cannot be used in PROC

•        The JCL cannot use stage cards.

For example:

//NORMAL EXEC STAGE, PARM=’ARTBR6000’,COND=(0,NE)

Documentation Standards:

Completion of the following forms is required as part of the Change Man Package for production acceptance:

•        Use forms 285B and 280, which can be found in CHNM.PROD.DOC l ibrary, Member Name =  CHNMFORM.

•        The following lists the required information on the forms . The forms contain a description of each header listed:

•        Batch job name

•        Job Description

•        Agency

•        Application

•        Set up instructions – The batch job must run in Control-M

•        Job dependencies

•        Restart instructions

•        Checkout instructions

•        Contact list with day & night numbers in case of abend or other problems

•        Agency escalation list and process — provide list or Data Set Name

•        Maximum drives allocated at one time

•        Job Class

•        Approximate run time

•        Start time

•        Frequency/holidays included?

•        Run restrictions

•        Output Description – Identify special form number that is required

•        Special run instructions

All Backup Jobs:

In addition to the required information on the 285 and 280 forms, all backup batch jobs are required to have documentation that provides the following:

•        Application backup cycles

•        Vault rotation/retention cycle and frequency

•        Disaster Recovery (Specify whether tapes produced by this batch job are part of Disaster Recovery.)

Output Special Forms Standards:

  • Batch jobs producing output to special forms such as, checks, must pass a quality assurance test run before the Change Man package is approved.
  • The quality assurance test for special forms, such as checks, shall follow GTA­-ITIS print operations security handling. See the “GTA Check Printing and Folder/Sealer Implementation Guide”.
  • GTA-ITIS Operations shall approve the package after the test run(s) is validated.
