I ve
been involved in copying libraries from one environment to another
before.
From what I see, there are three methods.
CPYLIB etc..
SAVRST to save file
SAVRST to tape.
Of the saves, you should do performance testing to see which one is
quickest. In my experience, using 3590 s, tape is by far the
quickest method.
I probably would not use CPYLIB as the access paths for each file will be
rebuilt on the fly. This will seriously hamper your system and may
take many hours to complete (if not days)
Another method you might consider is to use a replication package such as
DataMirror.
Hope this Helps

Subject: Duplicating a library.
Nightly we need to take a copy of our
production library and duplicate it to a Test environment for our support
people so they can play with almost current data.
I have been accomplishing this by backing up
the library with a save while active to a save file, then restoring the
save file to the test environment, then backing the save file up to tape,
and deleting it.
I would like to eliminate going to a save file
and just save to tape and duplicate the library. I don't want to restore
from tape to the test environment.
This is a 10 Gig library with 200 Physical and
logical files.
This library is used 27 X 7.
Can you do a crtdupobj on active
files? will it have to rebuild access paths?
I would appreciate anyone's thoughts on a good
solution.
Thanks Chris.
