Re: checkpoint interval

Sahrul,
Try dropping your LRU_MIN_DIRTY to 0 and LRU_MAX_DIRTY to 1. This will
cause ODS to do more background writes and should reduce your
checkpoint time. Also depending on the size of you buffer cache you
may need to increase the LRUS. I would try 16 or 32.

We are happy with our configuration, but since Last Monday, our online
perfomance
going down and also interval of checkpoin sometime took so long, about
50-170 second. We have checked no big transaction, no long transaction that
caused checkpoint interval like this. all transaction is on normal
condition.
Could somebody give some suggestion, what are the parameter relation with
checkpoint interval, what is exacly the problem, if we face problem like
this ?
here is our online param :
LRUS = 8
CLEANER=12
LRU_MAX_DIRTY=3
LRU_MIN_DIRTY=1
reply and suggestion are greatly appreciated......
