Re: [ADSM-L] Spanking my data.

I would concur with Kelly.  With rare exceptions, it's generally
advisable to do these activities serially.  Different environments do
them in different orders, but they tend to do them one at a time.  Doing
them simultaneously creates all kinds of contention issues.  Kelly
alluded to one with two processes asking for the same tape at the same
time.  There's also the load that many simultaneous queries and updates
puts on the database.

Besides, I've heard some places have outlawed spanking. ;)

Spanking is a good description.

Turns out the TSM will let you do all of that simultaneously to the
extent possible. Now, in some cases the nature of what you suggests
implies that certain things have to wait.  For instance, I can't have
one tape allocated to two processes (though, in some cases in 5.5 you
can).

So basically processes will stack up behind one another waiting for
access to volumes.

You are, however, advised to do all of these things with some sanity.
Most folks create scripts that they then schedule to do these things in
a reasonable order to take into consideration the various resources
required to perform the tasks.  We call this daily processing and again,
sanity is the watch word.  Do things in the proper order using the
resources effectively and the work gets done more quickly...

I'd like to hear some expert opinions on this forum.

What happens when you attempt to backup, migrate, move data, reclaim the
same pools at the same time?

Thanks in advance for your input.
