Re: [U2] [UV] Hash.Help
Bill, You aren't able to resize files that are open -- since you are in the account whose VOC you are trying to resize, it is open by default. So resizing the VOC becomes a little tricky; here's a recipe: 1) Logout or quit to UNIX and then get to the UniVerse prompt in another account. Make sure that no other users are doing anything in the account whose VOC you want to resize. *** MAKE SURE YOU HAVE A BACKUP OF THE VOC *** 2) Set a file pointer to the VOC you want to resize. SETFILE pathname_to_the_VOC QFILE 3) Do the resize using the pointer, as in: RESIZE QFILE 17 1237 4 Hope this helps, Jeff Fitzgerald Fitzgerald Long, Inc. http://www.fitzlong.com On 2/17/10 4:48 PM, Brutzman, Bill bi...@hkmetalcraft.com wrote: Our UniVerse system has been slow over the last few weeks.

Re: [U2] [UV] Hash.Help
Resizing the VOC is only for the non quiche eating real manly admins. I have found that the only way to do this is remotely via q-pointers from another account - and make sure you have triple backups, belts, braces (suspenders) and safety nets, parachutes and back-doors easily accessible.

RE: [U2] UV HASH.HELP error
HASH.HELP has improved over the years, but I sure wouldn't accept its results blindly! The most interesting part of your post, to me, is the variation in type recommendations -- type 10 v.s. 18. As you suggest, the modulo should be made a prime whether it's calculated by HASH.HELP or some other source. For the type, the basic problem with HASH.HELP is that it uses only an analysis of the record key patterns. This is inferior to a simulation approach. Of the available Universe tools I'd choose HASH.AID, testing all the types 2 through 18, and then looking at the resultant data (LIST HASH.AID.FILE) for smallest overflow and tightest hashing. HASH.AID isn't perfect as it doesn't report empty groups but at least it is a simulation rather than just eyeballing the record keys. Of course, the main thing is to keep those files sized! An implemented non-optimum resize is better than a theoretical perfect solution.

RE: [U2] [UV] HASH.HELP
My first guesses would be that either the file is corrupt or that it was being resized and the resize was aborted. I'd suggest running uvfixfile against the file (or FAST if you are using it.)
