Hi all,

I have one query regarding disp parameter.

I have a declaration like this:
Code:

//dd1  dd  dsn=test.bala.file1,disp=(new,catlg,delete),
//            dcb=(lrecl=80,recfm=f,blksize=400,dsorg=ps),
//            unit=sysda,space=(trk,(10,15))


my query is the number of times i am trying to create the above file it is getting created successfully.

but what i expect is it should give error like file all ready exist.

can anybody explain me the reason behind this.

Do you have a delete step prior to the create step ?

Is it created with NOT CTLG 2 somewhere in the JESYSMSG ?

Does your shop have an exit to scratch any pre-existing dataset that has DISP=NEW ?

Or, are you using some step in your JCL, prior to this step, like this:
Code:
//STEP005 EXEC UCC11RMS,TYPRUN=F

Hi,

As Expat mentioned, you might be using DELETE step priot to the creation step. Just check is this happening in your JCL.

below is my jcl :
Code:

//STEP02  EXEC PGM=SORT
//SORTIN   DD DSN=TEST.BALA.EXERCIS1,DISP=OLD
//SYSOUT   DD SYSOUT=*
//SORTOF01 DD DSN=TEST.BALA.FILEA,
//            DISP=(,CATLG,),UNIT=SYSDA,
//            SPACE=(CYL,(1,4),RLSE)
//SORTOF02 DD DSN=TEST.BALA.FILEB,
//            DISP=(,CATLG,DELETE),UNIT=SYSDA,
//            SPACE=(CYL,(1,4),RLSE)
//SORTOF03 DD DSN=TEST.BALA.FILEC,
//            DISP=(,CATLG,),UNIT=SYSDA,
//            SPACE=(CYL,(1,4),RLSE)
//SYSIN    DD *
      OPTION COPY
      OUTFIL FILES=01,INCLUDE=(46,2,CH,EQ,C'bs')
      OUTFIL FILES=02,INCLUDE=(1,6,CH,EQ,C'sp')
      OUTFIL FILES=03,INCLUDE=(1,6,CH,EQ,C'ap')
/*
//                 


in the jcl i am creating three files which are having some data in it,
but when i am doing some changes in the input file and trying to create
those three files with same name again they are getting created successfully and with updated data which i have changed in the input file.

Hi,

JCL looks ok, however, you could use DISP=SHR for SORTIN, if this is a stand alone JOB.

I usually use this type of code for my JOBs:
Code:
//JOBCARD
//STEP005 EXEC UCC11RMS,TYPRUN=F     
//*                                   
//STEP050  EXEC PGM=SORT,REGION=4096K
...
where STEP005 tells the OS to start a fresh run for this JOB. When tried the above JOB after commenting the //STEP005, there was a JCL error (JEM statistics) that SORTOUT already exist.

Can't guess what exactly happening at your end , we are missing something. Please show the SYSOUT messages as well.

Hello,

If you use tso/ispf 3.4 and list the dataset as 'TEST.BALA.FILE*', what does the system return? 3 files or more?

Your posted step is 02. What other steps are in the job?

Please run your job 2 times back-to-back and post the sysout info from both jobs.
