1. CONSIDER THE BELOW SCENARIO.
JOB SAMPLEJB EXECUTES THE PROGRAM SAMPLEPG AS PROVIDED BELOW.
//STEP01 EXEC PGM=SAMPLEPG
//INPUT DD DSN=INPUT.FILE,DISP=SHR
//OUTPUT1 DD DSN=OUTPUT.FILE01,
// DISP=(NEW,CATLG,DELETE),
// UNIT=SYSDA,SPACE=(CYL,(100,100),RLSE),
// DCB=(RECFM=FB,LRECL=80,BLKSIZE=0)
//OUTPUT2 DD DSN=OUTPUT.FILE02,
// DISP=(NEW,CATLG,DELETE),
// UNIT=SYSDA,SPACE=(CYL,(100,100),RLSE),
// DCB=(RECFM=FB,LRECL=80,BLKSIZE=0)
A NEW REQUIREMENT CAME TO STOP CREATING THE OUTPUT2. PROGRAMMER HAS MADE CHANGES ONLY TO THE JCL BY REMOVING THE OUTPUT2 DETAILS.
HE HAS FORGOT TO MAKE CHANGES TO THE PROGRAM SAMPLEPG. WHEN THE JOB RUNS AFTER THE CHANGES, DO YOU SEE ANY ISSUES. PLEASE JUSTITY YOUR ANSWER.
A. THE JOB COMPLETES SUCCESSFULLY WITHOUT ANY FAILURE. NO NEED TO
PROVIDE ANY DUMMY STATEMENT IN THE JCL. SYSTEM AUTOMATICALLY
CREATES A TEMPORARY DATASET FOR THE OUTPUT DD OUTPUT2 AND
COMPLETES THE EXECUTION OF THE PROGRAM SAMPLEPG.
FORMAT OF THE TEMPORARY DATASET THAT SYSTEM GENERATES IS
SYSYYDDD.THHMMSS.RA000.JJOBNAME.RGGNNNNN.
FOR SAMPLE JOB DETAILS, PLEASE DO CONTACT ME.
PLEASE NOTE THAT ANSWER TO THE QUESTION 1 IN WEEK5 QUIZ MAY VARY BASED ON SYSTEM INSTALLATION. IF THE SYSTEM ADMINISTRATOR HAS DEFINED A DEFAULT STORAGE CLASS AND DATA CLASS, THEN THE
TEMPORARY DATASET WOULD BE CREATED AS MENTIONED IN THE PREVIOUS
2. IN CA7, AT THE REQUIREMENTS OF A PARTICULAR JOB, YOU WOULD HAVE SEEN LEADTM (LEAD TIME). WHAT DOES IT MEAN WHEN THE REQUIREMENT HAS LEADTM=00 AND LEADTM=99.
EX: PROVIDE YOUR ANSWER CONSIDERING THE BELOW EXAMPLE.
JOB MAINJOB HAS JOBS REQJOB1 AND REQJOB2 AS REQUIREMENTS.
REQJOB1 HAS LEADTM=00 AND REQJOB2 HAS LEADTM=99.
A. LEAD TIME 00 – SPECIFIES THAT THE PREDECESSOR JOB MUST HAVE STARTED AND COMPLETED SUCCESSFULLY SINCE THE LAST RUN OF THE DEPENDENT JOB.
LEAD TIME 99 – SPECIFIES THAT THE REQUIREMENT IS NEVER CONSIDERED
INITIALLY SATISFIED WHEN THIS JOB ENTERS THE REQUEST QUEUE. THE
DEPENDENT JOB MUST COMPLETE NORMALLY WHILE THIS JOB IS IN THE REQUEST QUEUE.
EX: MAINJOB – Requirement REQJOB1 (LEADTM=00) AND REQJOB2 (LEADTM=99)
REQJOB1 HAS LEADTIME=00 MEANS THAT THE REQJOB1 JOB MUST HAVE STARTED AND COMPLETED SUCCESSFULLY SINCE THE LAST RUN OF THE MAINJOB JOB.
REQJOB2 HAS LEADTIME=99 MEANS THAT THE REQJOB2 JOB MUST COMPLETE
NORMALLY WHILE THE JOB MAINJOB IS IN THE REQUEST QUEUE.
