Re: Automatically compact databases from time to time (as a background process) Noel Grandin Thu Feb 16 04:00:18 2012

Perhaps we need to implement some kind of default timeout on how long a transaction can stay open?

Hi,

I would first analyze why it grows so much. Possibly an uncommitted transaction?

I have a related question:

Triggered by this request I tried what happens if I execute "shutdown
compact" but do not close my connection-pool as well and as one
could have expected the database was reopened at the first query after
the shutdown without a problem. I also tried starting a new
transaction while
the compact was busy and that worked as well.

I guess this is not quite so different from what you are trying to
implement (DB-Lock), are there any dangers to this aproach?
The nice thing is that I dont have to restart my application, I just
let it reopen the database. It does block all access to the database
during operation but thats fine with me.
