maybe db_archive is not needed, but just to be sure...

Oh, this is just of my mind, never tested



OK thanks, but apparently I need to run db_archive, which doesn't prove me the interest of using

DB_LOG_AUTOREMOVE :-(

logs still here :-(

If I run db_archive, logs will be removed, but can I check that DB_LOG_AUTOREMOVE does work !.

Thanks.

Hello,

I want to remove bdb log files. Scripts using db_archive can do that,
but I recently discovered on this list the set_flags DB_LOG_AUTOREMOVE
to place in DB_CONFIG, this solution seems cleaner to me !.
However, how can I tell my slapd to reread DB_CONFIG and hence take into
account that new setting. I heard again from this list that __db* files
contains the BDB environement, should I just start and stop slapd or
should I remove __db* file or something else ?
Is there a way to "see"  what is the current BDB evironement setting ?

Thanks.
