I know this is Universe, but on Unidata, I would make these files static, not dynamic. It is my opinion that a well sized static file will out perform a dynamic file. I only make files dynamic when they are about to blow the two gig file limit. Maybe this does not apply in Universe. But I thought I would raise the issue. -Rod

Used/free memory seems to be about the same all day long. If I look at the output of 'vmstat' it shows some blocks coming in and out, but that's about it. Im not really a guru at this stuff and Ive never found anything really worth while that tells you how to decipher information from these commands. Our 'current' files are; one file at 49899 records -rwxrwxrwx 1 root alperts 5261312 Feb 14 09:14 DATA.30 -rwxrwxrwx 1 root alperts 15978496 Feb 14 09:14 OVER.30 And one at 181784 records -rwxrwxrwx 1 root alperts 10811392 Feb 14 08:48 DATA.30 -rwxrwxrwx 1 root alperts 13197312 Feb 14 07:37 OVER.30 Our history files are; one file at 789278 records -rwxrwxrwx 1 root alperts 341465088 Feb 14 05:54 DATA.30 -rwxrwxrwx 1 root alperts 129693696 Feb 13 21:59 OVER.30 And one at 1805772 records -rwxrwxrwx 1 root alperts 343695360 Feb 13 21:59 DATA.30 -rwxrwxrwx 1 root alperts 109078528 Feb 13 21:59 OVER.30 I am going to experiment on a test machine. I will try playing with the GROUP.SIZE and SPLIT/MERGE LOAD. I am also curious to convert these records to static and see what happens with that. Ive been working with Universe for about 10 years and the files Ive worked with here have always been sized as such (dynamic files with approx same number of records) and I have never had to get into this sort of thing. Also, Ive started looking into the uvconfig params. I moved MFILES up. I thought this might be causing trouble. It was set to the default of 12. I kicked it up to 300. That didn't really seem to do anything for me.

Whenever I have encountered this type of problem there are usually oversized items involved. I MEAN OVERSIZED thus causing serious I/O and memory usage stats. Ensure the rollover process is not creating really large items. Maybe there is a log file that is getting too large due to too many updates at once. If you do find it to be the cause then let us know if you want help with it.

We have been running on this machine since October. I am just getting into some file cleanup, year end rolls, etc.. What is happening is that the machine comes down to a crawl. We were on DG/UX and this kind of thing never happened on that platform. I could 'roll' files, etc and I never experienced anything like this. Linux itself seems to be moving along fine. Anything in Universe takes almost 1/2 minute to get any response. Without the purge/cleanup programs running, everything is just peachy. The files are all Dynamic. The programs are doing readu/delete, write. That is read a record and write it to a history file and delete from current file. Or read a record, move this years data to last years fields and write the record back out. Anybody experience this sort of thing ? Anyway to tweak things up ? I have an idea that the files might not be 'sized' correctly. I also remember that Universe on DG/UX was tweaked specfically for that OS. So, maybe it was just more efficient at doing this kind of thing. Any suggestions would be appreciated. Thanks Anthony -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
