When you specify a relative (-x) GRS serializes on the base.

If you get JAL/DCS Thruput Manager from MVS Solutions then you can
convert the relative to the absolute prior to job initiation, and get by
this problem.  I don't know what other products exist that can do this.

Otherwise, you have to manually do the =3.4 or listcat yourself, get the
full name, and allocate it yourself using the full name, which usually
requires a JCL edit prior to submission.

Subject: Dataset contention on GDG


I have noticed dataset contention
Job A is running
//INPUT  DD DISP=SHR,DSN=GDG.BASE.NAME(-4)

Job B was submitted later and it is waiting for datasets:
//OUTPUT DD DISP=(MOD,CATLG),DSN=GDG.BASE.NAME(+0)


Q: is it normal ?
Why GRS minor name is GDG.BASE.NAME, not the GDS member name ?
Can I change it ?
