Thread: Checkpoint segments too small

Checkpoint segments too small

Hi list,

I'm running 8.2.4 and I've started to get these messages and even
though I googled for some answers I couldn't find any good info
against the 8.2 code base.

2007-08-05 04:00:58.815 CEST  LOG:  checkpoints are occurring too
frequently (17 seconds apart)
2007-08-05 04:00:58.815 CEST  HINT:  Consider increasing the
configuration parameter "checkpoint_segments".

Right now I use the default setting.

Is there any idea of raising these at all if I can't move them to a
separate disk?

Regards,
Henrik

Yes. Just make sure you have enough diskspace for them before you do it.
