How fast is fast recovery on V5
Hi We have been waiting 7 hours for a recovery to complete from what looks like 3.75 log files on Informix V5.3 with 2k page size. There had been some substantial deletes etc. just before it went down. Is this to be expected - shall we cut our losses and go back to a recent le…

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…

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…
