How long has a transaction or query been running?
Hi Jacob, checkpoints being blocked, if that really is what's happening, is a concern, but it certainly is not a transaction per se, much less its duration, that can do this. You can have as many transactions open as you want, even for extended periods of time, and still get all…
What triggers a blocking checkpoint?
Jacob: Need more details like the reported trigger in the onstat -g ckp report or the supporting sysmaster table. Since only a short list of checkpoints are kept online, the best thing to do would be to set up a cron job to run every 15 mins from 6:00 until 10:00 daily and post o…

Checkpoint problem.
Hello, guys! Our Informix server has stoped three times for a month. tbstat shows that all user processes (except two) are waiting for process "ckpt" which seems to be a checkpoint process. I noticed that in the Informix log file there were missing checkpoints for about 30 minut…
Java and Informix Dynamic Server 7.x
Hi friends! I am trying to do server-side java cgi programming to connect to I-ODS 7.x. Do you know how I can do that? I heard it is possible to use the jdbc-odbc bridge( intersolve or openlink's), but the performance is too slow, because of jdbc to odbc and odbc to jdbc convert…

Re: Too-frequent checkpoints; which parameters to check?
Actually, if performance is important this is what you want. The alternative is to have them less often but for longer periods of time. Since users are completely blocked during the checkpoint, they would not have no response for 5 or 10 seconds (for example) which can seem lik…

Too-frequent checkpoints; which parameters to check?
I've got a situation with On-Line 7.22 (SPARC, Solaris 2.5.1) where we get flurries of checkpoints at short intervals, during some update periods that look like: 23:35:07 Checkpoint Completed: duration was 2 seconds. 23:35:14 Checkpoint Completed: duration was 1 seconds. 23:…
Re: numerous checkpoints
The two most common reasons for checkpoints are 1) the checkpoint interval has been reached and 2) the physical log is over 75% full. If the checkpoints appear to be closer than the checkpoint interval, I would guess that your physical log file is too small. Madison Pruet…
numerous checkpoints
Hi, I don't understand reason why checkpoints occur so frequent. From my point of view, there are not any event that initiate a checkpoint (events described in INFORMIX-Online Dynamic Server Administrator's Guide Version 7.1 12-52). Could someone tell me another event, that is no…

Hey Online wizards What causes the check point required message on a "tbstat -"? I know one cause is when achive tapes needs to be changed(many thanks to Joe Lumbley's book), but what other things can cause the check point required message? A "tbmode -c" should force a checkpo…
