And I should clarify that the biggest part of my nightmare was having
someone do a RESIZE CONCURRENT on one of the largest major most utilized
files during business hours...

ugggghhhhhhh

Hi Debster,

Thanks for your suggestions.  We are very happy with FAST and given we have
well over twenty thousand files to maintain over 9 servers, FAST is
definitely the way to go.  Sure I could write my own but I am not in the
tools business and FAST does an excellent job.

The files were not being resized at the time and the point about gathering
stats on files that being updated is valid. However, we resize all files on
a six weekly cycle and the small change that is made during the stats
collection period would not be significant. But if the file is being locked
during stats collection that would be a major issue and would have resulted
in the failure experience.

Again many thanks for your input,

Stewart

A resize function will lock a file

And why collect stats when a file is active?

I had looked at FAST but given the recent nightmare I have just lived
through I am not so sure I would want to just allow an application to run
and act on the results.

Besides it's really easy enough to write a program to select a rotating set
of files you like to monitor, have it run HASH-HELP and capture the data to
a file.  This allows you the ability to inspect the results.  On more than
one occasion lately I have run across HASH-HELP results returning an
incorrect file type. (I also think I was a victim of Mark's Berkley
Bug...except the sep was 8 not 4)

Another option is to run a complete set of file stats weekly selecting your
top files in need of resizing from the results within STAT-FILE and
performing the calculation yourself within a program....

How many others remember having to hand calculate these with a set of file
stats in front of you?

Seems to be of the same era as remembering the sequence of keys to hit to
open an unresponsive tape drive on a mentor system

Or using the trick of blowing the tape leader into place when using the 12
inch tapes...<rut-roh that sounded kinda kinky!>

Hi All,

We currently use FAST for the resizing of files and part of the process is
collecting file stats for the purpose of calculating new file sizes,
separation etc.

I was wondering if running the stats collection process can be run whilst
the system is being used (files being updated etc) without causing any
issues?

I had a strange issue today when one of our program files could not be
opened and this caused a background process (phantom) to crash. On
inspection I could open the file there were no permission problems. I
restarted the phantom all worked just fine.  However, I noticed that our
Database Admins where running one of the FAST processes and thus my question
above.

All replies gratefully accepted.

Kind Regards,
