For DB_LOG_AUTOREMOVE to work, you must be checkpointing the database,
either with db_checkpoint running in oneshot mode, as a daemin process or by
setting up checkpointing in you slapd.conf file.  Once you are
checkpointing, bdb will autoremove the log files.

It still doesn't remove  log files :-(

[root@babylone /var/lib/ldap/int]
$ /usr/sbin/slapd_db_checkpoint -1
$ /etc/init.d/ldap stop
Arrêt de slapd : [ OK ]
[root@babylone /var/lib/ldap/int]
$ /etc/init.d/ldap start
Démarrage de slapd : [ OK ]
[root@babylone /var/lib/ldap/int]
$ ls log.* | wc -l
461
I've even run db_recover to be sure that BDB env is reset .
by the way, that production server where I test is running openldap 2.1.30-1 which uses libslapd_db-4.2.so, perhaps that feature was not available for these releases ?
can I start db_checkpoint -1 while slapd is running ?

I would:

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.



jehan.procaccia disse:




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.
