HRECALL – MASS RECALL IN BATCH MODE
Sometimes you would require recalling a lot of datasets that have initial HLQ common. This can be achieved by submitting the below JCL.
// JOB CARD
//PGM EXEC PGM=IKJEFT01
//SYSPRINT DD SYSOUT=*
//SYSTSPRT DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//SYSTSIN DD *
HRECALL ‘HLQ1.HLQ2.**’ NOWAIT
//*
DELETE ALL GDG VERSIONS WITHOUT DELETING BASE
Below JCL would delete all the versions of the GDG without deleting the BASE.
// JOB CARD
//PGM EXEC PGM=IEFBR14
//YOURGDG DD DSN=YOUR.GDG.BASE,
// DISP=(OLD,DELETE,DELETE)
LISTCAT – BATCH JOB
Please fine below the Batch job that you can use to use the LISTCAT command on a VSAM FILE. Output of the LISTCAT can be seen in SYSPRINT.
// JOB CARD
//STEP01 EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=*
//SYSIN DD *
LISTCAT ENTRIES(YOUR.FILE.NAME.HERE) ALL

—————————-
1. WHAT COMMAND IS USED TO DELETE ALL LINES FROM A PS/PDS
MEMBER. (NOT LINE COMMANDS)
2. WILL WE GET AN ERROR IN STEP 2 OF THE BELOW JCL. IF YOUR
ANSWER IS YES, WHAT PRECAUTION STEPS CAN BE TAKEN TO AVOID
THE ERROR.
STEP 1. DEFINE VSAM
STEP 2. RUNS A COBOL PROGRAM WHICH OPENS VSAM FILE AS INPUT.
3. WHAT HAPPENS TO THE OPENED DB2 CURSOR (DEFINITION BELOW)
AFTER ISSUING A COMMIT IN THE PROGRAM. WHAT ACTIONS CAN BE
TAKEN TO AVOID THE PROBLEM,IF ANY.
DECLARE ACT_CUR CURSOR FOR
SELECT PA_NO FROM ACCOUNT
KNOW YOUR MAINFRAME – WEEK 2
—————————-
1. HOW DO YOU SUBMIT A JOB AUTOMATICALLY AFTER A JOB FINISHES.
2. HOW DO YOU DO A SRCHFOR IN A PDS FOR A STRING THAT IS IN
MIXED CASE (Ex: AbCd)
3. HOW DO YOU TERMINATE A DB2 UTILITY THAT IS STOPPED DUE TO
AN ISSUE WITH ITS PREVIOUS EXECUTION.
KNOW YOUR MAINFRAME – WEEK 1
—————————-
1. WRITE THE SHORTEST COBOL PROGRAM THAT IS COMPILER ERROR FREE.
2. WRITE A SORT CARD TO CHANGE ALL OCCURRENCES OF A CHARACTER TO
A DIFFERENT CHARACTER FROM THE INPUT FILE.
3. HOW DO YOU REARRANGE THE COLUMNS IN SPOOL (SDSF), SUPPOSE YOU
WANT TO HAVE Max-RC COLUMN AS THE THIRD COLUMN.
Hi All
Recent Days We have been hearing many myths that were against Mainframes. I have found a nice article that gives a sound voice for Mainframes. Please go through the same.
