Ravi - How expensive are the checkpoints ? Why would an Informix DBA write a perl script to try and predict when the engine is going to do a checkpoint ? Exactly what does onmode -b do in Informix ? Is it documented ? Why would an Informix DBA recommend that it be manually issued before a 'real' checkpoint ? Does it work all the time ? What are the potential recovery problems that can be caused by doing this ?

The questions are purely rhetorical, and I'm not trying to throw fuel on the fire, but this comment struck me as just a little disingenious. Received on Wed Mar 31 2004 - 23:43:47 CST
