Eileen, I believe what you are seen is the enqueue on the GDG base and not a specific level, since the +1 level is not actually resolved until DSN closing time. You never specified which one started first (unless the started exactly the same time), but MVS will get all the allocation stuff out of the way at the start of the job execution time.
Based on what you stated I believe JOBB started first which is probably why JOBA could not resolve its GDG level.

JOBA allocates a new gdg level with DISP=OLD DSN=XXXX.TBC.PTNT.SASFILE.NEW(+1),UNIT=TAPE3480, DISP=(NEW,CATLG,DELETE),DCB=(MODLDSCB),LABEL=RETPD=4 and in several later steps references the gdg via DD DSN=xxxx.TBC.PTNT.SASFILE.NEW(+1),DISP=OLD 2. JOBB is running at the same times but references the current level of the gdg: DD DSN=XXXX.TBC.PTNT.SASFILE.NEW(0),DISP=OLD in addition, several other jobs were also running which allocated the dataset with DISP=SHR DD DSN=XXXX.TBC.PTNT.SASFILE.NEW(0),DISP=SHARE 3. JOBA remains on the execution queue waiting for the dataset: IEF863I DSN = XXXX.PTNT.SASFILE.NEW JOBA IEF099I JOB TBCDAILY WAITING FOR DATA SETS now, why is the IEF863I msg indicating just a dataset name with no gdg level. and since JOBA and JOBB are referencing different gdg levels, why should should JOBA be waiting for the dataset? ---------------------------------------------------------------------- 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
