Hi,
I'm experience using expire_log_days and don't work. I set this
parameters
in the CNF and when the time of ( for example 5 days) is in, don't
delete
anything.
On my expirience, this parameters don't work ( 5.0.27).
I am testing this now (on 5.0.40) and will see how it works out.
OK initial testing of this has shown no problems with the rolling over
that happens when the server starts/stops:

The only other one to test now is test that this also happens when a
binary log rolls over.
Do keep in mind that expire_logs_days only gets triggered at a) server
start up b) the time a binary log has to roll over.
If your binary logs do not roll over for quite a period of time (i.e are
lower load systems) that still stay up for long periods - you might not
see a log expired for some period.
Anyway, I'll still check out binary log rollover as well..
Cheers,
Mark
