Two reasons we don't get DB2.
1. It costs money.
2. I.T. management despises z/OS.

Aside from the how of creating your own VVDS, I'm concerned about the why.
OK, if an existing VVDS fills up, that's a why. Otherwise, you might
consider creating your own VVDS at the outset if the default size or
location is likely not appropriate for the volume. For example, a huge
volume like

My advice is to use multiple DASD data sets to get as much parallel I/O
as possible. Also, human interaction is responsible for tremendous

Without knowing the chain of events, it is hard to understand what occurred.
If you still have the syslog from then, or the Logrec, or any SVC DUMP, you
