All,
I have a z/VSE program that I want to start using with z/OS. The program
issues several CCWs to the DS8000, such as SNS, SSS, RCD, & PSSF that
are either volume specific or subsystem specific. Not file specific.
My first question is in the area of getting access to a specific volume
on z/OS.
In z/VSE, I just do an ASSGN to the disk and issues the EXCPs.
On z/OS, I expect I need to perform an OPEN against the volume using
something like:
//SOURCE DD UNIT=3390,VOL=SER=AVOLID,DISP=OLD
Any pointers would be appreciated.
My second question relates to 'authority'.
On z/VSE, I have to tell the operating system that I am actually 'DSF'
before it will allow me to issue these CCWs.
Do I have to do something special on z/OS?
Thanks,
Tony Thigpen
