---+ Issues which limit the number of files in an HP3000 Group

If you have 'too many files in a group' OR 'too many files with a similar name' then you will start having problems when trying to delete some of them.

I use a modified version of MPEX's flexible %LISTF file !REPORT.LISTF.VECSL to warn me when we are approaching the 'too many files in a group' limit.

afaik, there is no 'hard' limit...it's one of those 'it depends' sort of things.  however, when you get into the 40k-50k range, you're on thin ice.

you can pick up a copy of filecnt from jazz...

.....and not reinvent the wheel :-)

fwiw, i run this script in a weekly job with a threshold of 20k -- as my early warning system :-)  i've told the programmers at 25k they start getting emails and trouble tickets...at 30k and if there's still no response, i start getting rid of files.

btw, if you find yourself in this situation (and you're on the low-end of having too many files) you can try getting rid of the files *backwards*.  (eg, purge 'z' then 'y' then 'x'...)  if you're really in trouble, the only thing (that i know of) to be done is to purge the group/directory.

btw #2, this isn't a problem unique to mpe.  you can have the same sort of problem on unix....

i hit this 'too many files' problem several years ago....ended up having to reload a 200-250gb system as a result.  it's not the kind of 'fun' i wish to have again...
