onstat -g seg reveals several virtual segments many show a pool summary of 17184.H.sd
Stuart: Yes, RALLOC_MODE is a diagnostic setting only used temporarily on advice from tech support to help them diagnose specific suspected memory issues. It has been known to cause memory allocation issues of its own in the past. You should unset that. Art ----------------------…

What prevents a RSS to roll forward as fast as its primary?

Informix HA Cluster and CM
OK, here's how it goes. You have two servers, a primary and an HDR secondary, call them node1 on host1 and node2 on host2 and you have a single Connection Manager, call it CM1 on host3. The servers each have a TCP and shared memory connection type defined, call them node1_tcp and…
Want to DROP an empty rootdbs chunk
David: No worries. Except for the catalog tables and a handful of others, nearly all of the "tables" in sysmaster are not actually tables at all, but windows in to memory structures which cache on-disk structures. Those, like the chunk table, dbspace table, etc. are what are upda…

Memory issue on Informix primary server
Amit: Casey's right, it looks like most of the memory allocated is unused. I had missed that. Here's what I think happened. As I said Solaris is VERY SLOW to allocate shared memory, so when a session needed more memory the engine requested another 3GB segment. It took so long tha…

PDQ mixed with OLTP

SHARED MEMORY ALLOCATION
Note that DS_NONPDQ_QUERY_MEM is limited to 25% of DS_TOTAL_MEMORY. Neither DS_TOTAL_MEMORY nor DS_NONPDQ_QUERY_MEM are carved permanently out of SHMVIRTSIZE but are allocated from there as needed and released. I can alleviate Benjamin's fears. The total of DS_NONPDQ_QUERY_MEM u…

DS_NONPDQ_QUERY_MEM not changing

Hi, I looked through all your onstats. Some observations: 1. The values used for DS_TOTAL_MEMORY and DS_NONPDQ_QUERY_MEM are way too high. SHMVIRTSIZE 201376 DS_TOTAL_MEMORY 26214400 DS_NONPDQ_QUERY_MEM 1310720 16GB RAM So that's just under 200 Mb for SHMVIRTSIZE but 26 Gb fo…

Temp dbspaces in RAM
Hi, as long as Informix can handle the memory it is faster to spend the memory for the virtual SHM-segment. I made several tests with RAM-disks and the DS_TOTAL_MEMORY parameter. It's better to use DS_TOTAL_MEMORY and PDQPRIORITY. But if your servers' process space has reached t…
RE: PDQ_PRIORITY parameter!
PDQ is 100 words or less. This may even be reasonably accurate. When you run a query, issue a SET PDQPRIORITY x where x is some valus between 0 and 100; You can also export the environment variable PDQPRIORITY=x I'm not going to try to analyze what you've set it to here witho…
RE: PDQ_PRIORITY parameter!
In order to utilize PDQ, you either need to set PDQPRIORITY in either your SQL (or 4GL) or your environment. In SQL: set PDQPRIORITY <some_value> In environment (UNIX presumed): export PDQPRIORITY=<some_value> John Carlson Informix Database Administrator EDS - WHSmith USA 32…
PDQ_PRIORITY parameter!
Note that PDQPRIORITY values of 0, 1 & 2 are special values. 0: No parallelism 1: Minimal parallelism (same as LOW) 2: Lowest setting that give full parallel features. See the Performance Tuning Guide and the Administrators Guide for details. Art S. Kagel Murat YILDIZ wrote: …
