CHK REQ times suddenly getting very long
Clive: You should do an IIUG TechTalk about managing that many TS devices in Informix! That aside, here are the mechanics of what's happening, maybe it will help you figure out what changed and how to manage that: When a checkpoint is triggered the engine locks a mutex latch that…
onstat -x and sysmaster:systrans
WOW! I feel so anachronistic! Here folks are discussing release 15 and "large tables" and I'm back in release 12! I am almost certain Lester K must have posted a query about this but I can't find it. So I ask the community: Here's a sample of output from onstat -x , filtered …
Long transaction message discusses a strange number
Hi Jake, for matching " Aborting Long Transaction: tx: 0x1d298fba8 ..." with onstat -x, simply go by this tx address. The tx_id's use, for the user, mainly is to identify the transaction in onlog output, in combination with LSN info (log unique ID + log position within that log).…
12.10.FC15W1AWE Blocked in LONGTX
Could it be that the rollback was still going, but had hit the LTXEHWM threshold? onstat -x would have shown some movement if that was the case. If the logs had got to the point where the next log had an open transaction, you could have tried adding logs manually with onparams -…
Large memory segment vs smaller ones
Hi Dennis. Yes: " vmo -p -o v_pinshm=1". You must have RESIDENT 2 or more for large pages as they must be pinned. The "rsam" pool is in the dynamic segment. You need RESIDENT 2 or more. It doesn't sound like the problem is with the buffer pool but the "rsam" pool. Your BTR is fin…

Buffer wait occurs when performing INSERT in multiple sessions
You have to only peripherally related problems. The issue about not enough KAIO resources is an operating system tuning parameter. You can read the maximum value and set it here: $ cat /proc/sys/fs/aio-max-nr 65536 echo 131072 >/proc/sys/fs/aio-max-nr # set new maximum And see …

John: There can be several reasons for a session remaining in the "ready queue" (aka ready state) for several seconds. Here are the most common that I can think of off the top of my head: It is waiting for some resource like IO, a condition, a latch, a database lock (I believe yo…

Buffers and LRU.
The buffer pool is the page cache of the engine. The LRUs are simply a means of chaining the buffers together. There are two chains per LRU - the free and the dirty. (Actually a free buffer has a page in it, but it is not dirty.) There are multiple LRUs so that if a thread tri…
