Could the problem be related to the && dsns being the same as the ddnames?
Debbie Mitchell Utica National Insurance Group /snip Hi All. Once again I look to the group for help. I am at a total loss and have test extensively. This is the issue: If I use the following && JCL the job fails consistently with an 0C4: //WORK01 DD DISP=NEW,UNIT=SYSDA,SPACE=(CYL,(4300,5)), // LRECL=8192,BLKSIZE=0,RECFM=VB,DSN=&&WORK01 //WORK02 DD DISP=NEW,UNIT=SYSDA,SPACE=(CYL,(4300,5)), // LRECL=8192,BLKSIZE=0,RECFM=VB,DSN=&&WORK02 //WORK03 DD DISP=NEW,UNIT=SYSDA,SPACE=(CYL,(900,5)), // LRECL=8192,BLKSIZE=0,RECFM=VB,DSN=&&WORK03 //WORK04 DD DISP=NEW,UNIT=SYSDA,SPACE=(CYL,(900,5)), // LRECL=8192,BLKSIZE=0,RECFM=VB,DSN=&&WORK04 I have 4 PUBLIC volumes. If I use this JCL which uses permanent datasets the job works everytime: //WORK01 DD DISP=(NEW,CATLG),UNIT=SYSDA,SPACE=(CYL,(5,5)), // LRECL=8192,BLKSIZE=0,RECFM=VB,DSN=TRAM1.WORK1, // VOL=SER=BACK09 //WORK02 DD DISP=(NEW,CATLG),UNIT=SYSDA,SPACE=(CYL,(5,5)), // LRECL=8192,BLKSIZE=0,RECFM=VB,DSN=TRAM1.WORK2, // VOL=SER=BACK09 //WORK03 DD DISP=(NEW,CATLG),UNIT=SYSDA,SPACE=(CYL,(5,5)), // LRECL=8192,BLKSIZE=0,RECFM=VB,DSN=TRAM1.WORK3, // VOL=SER=BACK09 //WORK04 DD DISP=(NEW,CATLG),UNIT=SYSDA,SPACE=(CYL,(5,5)), // LRECL=8192,BLKSIZE=0,RECFM=VB,DSN=TRAM1.WORK4, // VOL=SER=BACK09 /snip ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
