Hi Buchan,

Thank you very much Buchan. So the thing I understand is that during recovery, If it goes through log files then it tries to match the database entries and log entries. is this right? and I just want to know about following things. 1. If I include "checkpoint" then will my ldap processing get slow because I have to upload millions of data every day? 2. what time and kbsize you suggest I should set in checkpoint for such case? 3. If I include "checkpoint" and "set_flags DB_LOGS_AUTOREMOVE" then will log files get deleted automatically or I have to run db_archive?

Regards, Mukim Pathan

Hi all,

I am unable to understand the answers for following question which i got

on

...

net. This might be naive questions but I really need to know the answers.

1. why does ldap write log files and what are its content?

To ensure that changes aren't lost, while getting decent performance. The same reason any database has transaction logs.

...

2. why does ldap go through all log files during recovery?

Most likely because you didn't configure checkpointing, see the 'checkpoint' directive in 'man slapd-bdb' and 'man slapd-hdb'.
