I know that you can specify the database DSN in the JCL, but is there a way to use the same dynamic allocation "feature" of IMS DBB/BMP?
I think there might be a parm in DFSRRC00...but finding details of those parms (their meaning) is getting frustrating!

Dynamic Allocation in IMS is implemented through the DFSMDA macro. See IMS System Definition Reference manual.
Make sure your //DFSVSAMP DD dataset does not specify NODYNALLOC

I found the Parm info, thanks for the link.
As for dynamic allocation,,, ARG, I should have know that NODYNAM was specified (I cannot imagine why anyone would specify that!).
Once I removed that from the DFSVSAMP pool def all was well.
IMS is like riding a bicycle, once you do it, it appears you never (completely) forget it! Even though the last time I worked with IMS was over 20 yrs ago!
Thanks to all the repliers!
