BUFFERS & RA_PAGES
In the performance tuning manual for OnLine 7.x, Informix recommends that you set your buffers to 25/20% of physical memory. My question is, what unit are we meant to be measuring memory in. I have presumed kilobytes, so that for my box with 64 Mb, my buffers are set to 16000. If…
Buffer sizing
I've been reading the Performance and Tuning manual and have some questions regarding the amount of buffers to use. I'm running ODS 7.22 on a system with a Gig of memory and a 4K page size. According to the manual on page 2-29, it says that buffers should be set between 20-25% …

All: I am having a problem with online ver 7.10.UD1 running on AIX 4.1.4.0. When I run a query on a view that joins many tables online begins allocating additional shared memory until it hits an illegal address. At this time the query hangs but the engine stays up. If anyone c…

You need to avoid dynamic shared memory segments on HP at all costs. If your SHMVERTSIZE is 60000, I would suspect that would be enough. However, if your application is leaving a lot of open statements (i.e. not issueing a FREE on a prepared statement or CURSOR) then each user t…
