Thanks Dick Scherrer. I will check with my local support team.
Sorry, i have a very basic question on dataset sharing.

Hello,
And tape datasets should not be specified with disp=shr. . . A tape volume cannot be shared. . . |
I have a question here. Although, i have mentioned as DISP=SHR for one of my test job (DASD file), dataset cannot be used simultaneously by two jobs. It shows contention. So, ideally what is the difference b/w DISP=OLD & DISP=SHR for the input file. |

Hello,
At the top of the page is a link to "IBM Manals". The second "set" includes JCL information. In the Language Reference for your environment, read about the DISP parameter.
The flashlight/tubelight near the top left is the manual Search facility.
If you find something in the manual that is not clear, post what you found and your doubt about it. Someone will be able to clarify.
Onn systems where i have some amount of control, shr is only used for datasets that would properly have multipleconcurrent users/processes (like a vsam file or a pds). |
