Hi Folks,

Somebody please enlighten me. If you're trying to scratch a dataset on a pack, and somebody else is in the middle of doing an IODF change at the time, what is the difference if you are obtaining a copy of the UCB (to determine what's on the disk pack), or the real UCB itself? I'm not expecting a complete answer from somebody, but I'd at least like a reference to a manual or manuals where the perspective and advantages/disadvantages of copied, (and captured) UCB's is explained, as opposed to the real UCB's. I want to read about it. Please show me where.

    Thanks.

    All the best........

Sam
