Oliver,

My experience would say that saving multiple libraries in a single
SAVLIB command will proceed significantly more quickly than multiple
executions of the SAVLIB command on individual libraries.  The system
does a lot of preprocessing prior to saving a library; it formats the
directory structure information which needs to get written to tape
before it starts to actually write to tape.  By saving multiple
libraries in a single command it will start to process the directory
structure of library #2 while writing library #1 to tape.  By issuing
individual commands, you lose this overlap.

There will be no differences in recovery from the tapes which result
from either save.

The message regarding excessive locks can be disregarded on a save.
This large number of locks could possibly be a sign of a program in
trouble so a warning message is issued.  When saving a large library you
should expect this message.

Regards,
Andy Nolen-Parkhouse
