Objective

• Understand the capabilities and limitations of CA-7

• Monitor CA-7 activity and resolve problems

• Understand the various CA-7 queues and their

importance in job tracking.

• Define jobs to CA-7

• Schedule jobs efficiently in CA-7

• Define job triggers

• Define job requirements

• Restart abended jobs through the CA-7/CA-11

Interface.

• Understand how JCL is handled by CA-7

3

Why CA-7?

Reduce Manual Interference.

Reduce Efforts and Time.

Maintain Log and history.

Maintain Job Flows and hierarchy.

Atlast its Easy Execution of Batch.

4

DISPLAYING THE ENVIRONMENT

Queue commands

LQ Command

LRDY Command

LACT Command

LJES Command

LRLOG Command

LPRRN Command

5

Queue Commands

LQ : List the Jobs in queue.

To list specific Job, use LQ,JOB=QB*. This would list all the Jobs in queue job name starting with QB.

LRDY: Lists all the Jobs in Ready Queue.

Eg: LRDY, JOB=QB*

LACT: Lists all Jobs on Active Queue. Ie Execution Queue.

LJES : Lists all the Jobs in JES (Job Entry Subsystem)

queue.

LRLOG : History of Job Execution.

LRLOG, JOB=<<JOBNAME>>,DATE=*

6

Queue Commands

LPRRN : Displays the last time Job was executed.

LPPRN,JOB=<<Job Name>>.

XQM : List all job which came in the queue.

For eg : xqm,job=gtb* -------------- CA-7 QUEUE MAIN

F-JOBNAME---J--I--E--U--N-SHJV

GTBAREND 9 . . . .

GTBASEND 2 . . . .

GTBASINI . . . . . H

GTBITEND . . . 1 .

In this the job GTBASINI is in hold. if you want to release it , put " r" in the left most side of the job.

To restart the job, "f" in the left most side and then use the appropriate option.

To cancel the job, enter "c" on the left most side.

7

Queue Commands

LPRRN : Displays the last time Job was executed.

LPPRN,JOB=<<Job Name>>.

FSTRUC : It will give whole flow of jobs taking jobname mentioned above at top of the hierarchy.

FSTRUC,JOB=<<JOBNAME>>

FRJOB : Reverse hierarchy, same as the stuff above.

FRJOB,JOB=<<Job Name>>.

• The Job Screen

• Schedule Ids (SCHIDs)

• The Job Scheduling Screens

• The Primary Job Scheduling Parameter Edit

Screen

• The SCHDMOD Screen

• Job Triggering

• The Job Trigger Screen

JOB MANAGEMENT

RUN : To run job independently

RUN,JOB=JOBNAME

RUNH : It will put job in queue with hold so you can do jcl

edit ie u can give file override etc before running that.

RUNH,JOB=JOBNAME

DEMAND : It’s same as RUN except it also initiate the jobs

which are being triggered by this.

DEMAND,JOB=JOBNAME

DEMANDH : It is same as DEMAND except it put the job in queue with hold so that you can do jcl edit , file override etc.

DEMANDH,JOB=JOBNAME

LJCL : It will display the jcl of that job.

LJCL,JOB=JOBNAME

Some Useful Commands

Command Description

D;C;1 To goto CA7 Login Screen from ISPF menu

XQM Maintenance Queue Screen

LQ Ready/Active Jobs

LACT Active Jobs

DB;3;6 Putting a Job in HOLD (User Hold)

H Putting a Job in HOLD (while in Queue)

E Edit an job

X To Release the HOLD

F Resubmitting the Job

X -- Resubmit For Production

X -- Force Completing the Job

LJOB, JOB=<JOB NAME>, LIST=ALL To know all the Jobs related to the job

LJOB, JOB=<JOB NAME>, LIST=TRIG All the jobs triggered by

LJOB, JOB=<JOB NAME>, LIST=DEPJ All the jobs which are dependant on this job

LJOB, JOB=<JOB NAME>, LIST=RQJOB All the requirements (Jobs/Schedules)

DEMAND, JOB=xxxxxxxx, SCHID=nnn, DOTM=hhmm, SET=SKP To run a job ahead of its schedule

11

Some Useful Commands

1. LQ,JOB=<job initial*> / <job name>,LIST=ALL

LQ,JOB=<job initial*> / <job name>

This command gives us the list of Jobs present in Queue and their status. Also gives the requirement details and the current status of Job.

2. LJOB,JOB=<job initial*> / <job name>,LIST=ALL

This command gives us the list of all available details in CA7 for a particular Job. This also gives the requirement details of the Job at the end of the output.

JOB INFORMATION

TRIGGER INFORMATION

SCHEDULEING INFORMATION

STEP AND DD INFORMATION

REQUIREMENTS AND NETWORK CONNECTIONS

12

Some Useful Commands

We can extract all above information one at a time using below commands-

JOB INFORMATION

LJOB,JOB=<job initial*> / <job name>,LIST=JOB

LJOB,JOB=<job initial*> / <job name>

TRIGGER INFORMATION

LJOB,JOB=<job initial*> / <job name>,LIST=TRIG

SCHEDULEING INFORMATION

LJOB,JOB=<job initial*> / <job name>,LIST=SCHD

STEP AND DD INFORMATION

LJCL,JOB=<job initial*> / <job name>

REQUIREMENTS AND NETWORK CONNECTIONS

LJOB,JOB=<job initial*> / <job name>,LIST=RQMT

13

Some Useful Commands

3. FSTRUC,JOB=<job initial*> / <job name>

This command lists the entire job flow with respect to the jobs and their subsequent triggers that are triggered by the job specified in the command.

4. LRDY,JOB=<job initial*> / <job name>

This command displays the Ready Queue which is where the JCL Check of the job takes place.

When a job is released for execution it first enters the Ready Queue before moving to the JES Queue for Execution.
