Checkpoint lays down a marker of 'all transactions up to this marker are complete and in the tables' recovery finds the last checkpoint, does a consistency check, then runs the transactions remaining after that forward until it gets to the end of the transactions logs.

Hi,

can anyone tell me how to empty  the duplicates database ? I found
out that cyr_expire -E days  allows to erase  duplicates older than
days days.
But this doesn't work with days equal to 0. Is there some other trick
to empty the duplicates database?


Using days=0 will leave all entries.  The closest you can get to with
cyr_expire is days=1.  If you truly want to empty deliver.db, then
stop  the server, checkpoint (and possibly recover) the BDB
environment and then remove deliver.db.


This works fine ,thanks. Although I do have one question left. The *ctl_cyrusdb allows *to checkpint with the -c flag and to recover with the -r option. From what I understand checkpointing is needed to have a good backup if something goes wrong. And the recover restores all database files from the latest checkpoint. But what happens with changes or new mail received between the last checkpoint and failure point?

kind regards,
Pieter
