David, I see the confusion now. The English phrase, "Needs to acquire a buffer," is too vague. There are really two major cases, but the manual is only addressing one (the rarer one). The cases are: 1. The required data is already in the buffer pool. In this case the thread nee…
Best Use of Free Memory
BUFFERS is generally a good place place to use extra memory, subject to a couple caveats: 1. If the working set already fits in the current buffer pool, adding still more buffers will not produce any noticeable performance increase. Check "onstat -g buf" output for your %cached.…

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…
Shared memory
My director told me that Digital dialed into our Unix box (AT&T running Informix 5.05) and saw that every sqlturbo is getting 5000 pages of memory. Does anyone know if this set in the tbconfig file? I can't find any information about this. If I can reduce this, it may benefit …
Shared Virtual Memory Question/Engine Shutdown
Our project site recently received a binary executable from a sister site which updated approximately 5000 stored procedures. The executable brought down the engine due to shared memory limitations. When looking at the data (onconfig, memory on machine, etc. as stated below), t…
