JCL Interview Questions

One of the approaches I can think of is instead create 3 procs and call the proc depending on the value in control card (populate proc value name from control card).

place Cond=(0,EQ,step1),(0,EQ,step2),(0,EQ,step3) in the the 4th step

the best way for this problem is give cond=only.

Using IEBEDIT utility to run a particular step with out use of COND Parameter

In job-card place "Restart=step100,cond=(0,LE)"

JES2 in this it will release the resource after completion every step execution that resource can be used by any other user.

JES3 it will release the resource only after the completion of all steps execution no other program can access that resource util the completion of exec.

JES2 processing is considered to be independently controlled.
JES3 processing is considered to be centrally controlled..

Position parameter has specific order in a program ,if you want to skip particular parameter then you must type comma for that.It always follow JCL job statement.
keyword parameter is unlike positional parameter it can be codec any order.

Positional Parameters are:- a).Sequence predetermined b) Parameters separated by commas c) Omitted parameters must be indicated by two consecutive commas. d) Installation dependent EX: //JOBNAME J...

The parm parameter is used to passed data from jcl to cobol program.
The max 100 character we can sent by parm parameter including special character.
And value get by code s9(4)comp var in linkage section

Whether it simple Cobol program or an COBOL-DB2 program. passing PARM value & reading it with in program is same for both. - We have to define an variable for PARM in linkage section - LINKAGE SECTI...

SCRATCH Scratches a data set or a member from a DASD volume. RENAME Changes the name or alias of a data set or member residing on a DASD volume. CATLG Generates an entry in the index of a catalog. ...

S13 comes, when the control card specified in SORT CARD is not available.

S013 will come the member u r tying to acess was not available in the pds

It is a data utility which is used to create new or empty dataset.

It is used for creating as well as deleting the datasets, it should be the first step in the jcl to delete the duplicate datasets which were created by the last job run and which was failed due to some abend..

e pdsname(membername)

No,we cant create PDS member by using 3.2 option.

if you want to create member then you can write member name in front of PDS file.
ex: GTO8838.YOGI.JCL(MEMBER1)

We can sort the two input file into two output file. "jcl //TDPSNPPJ JOB (9927),SANDEEP PAL,CLASS=D,NOTIFY= // MSGLEVEL=(1,1),MSGCLASS=U,TIME=(0,1) //STEP1 EXEC P...

We can copy two input files to two output files in JCL using ICETOOL. //JOBNAM1 JOB (123),XY,NOTIFY=&SYSUID,CLASS=X,MSGCLASS=X //* //STEP01 EXEC PGM=ICETOOL //TOOLMSG DD SYSOUT=* //DFSMSG D...

CPU time is not enough...

We get S322 abend when the program takes more execution time than CPU time .

We can avoid this kind of sistuation by using the TIME parameter.

in that area you have specified destination,it may printer or system spool?

Thanks in Advanced..

SYSPRINT: Default output dataset for Printable output.

SYSOUT: Default output dataset for System messages.

Use IDCAMS to print the records present in dataset.
If present, the job will end with MAXCC 0000 otherwise MAXCC 0004 i.e. empty file.

Thanks,

By using eibedit utility we can do it.

You can do it with IEBEDIT utility only. I would believe that DPRTY in the STEP will not serve this purpose. DPRTY coded on the step level is just ignored. DPRTY is a very old JCL keyword that wa...

You have to write a JCL to run a cobol-db2 program. Can you please give your JCL if you need any changes.

JCL: JCL is a language, We write JOBs in JCL laguage that is understood by Mainframe and job is executed, space allocations & other resource allocation is done according to the keywords specified by ...

JCL: is Job control Language.Through jcl we can decide what job has to be run what programs needs to be run.
JES: Job entry System : This will take care of the execution of the job . when a job is submitted it will allocate space for execution and will help in execution

using LABEL parameter RETPD(retention period)/EXPDT(expire date)

LABEL=EXPDT=12120(dataset expire on 120th day of 2012)
LABEL=RETPD=200(dataset is retained for 200 days)
