RE: LDAP Issue: Logging region out of memory; you may need to increase its size
Hi,
Thanks for the following information. Can you please provide your input for the following queries below:
•Is database cache is all that I have to take care off only?
•How to decide the value of ‘set_lg_regionmax’ parameter?
•For below problem should I need to increase the value of DB cache size or ‘set_lg_regionmax’ if the issue occurs again.
• Is the ‘index generation failed’ issue linked to the logging region issue?
Regards,
Gurjot Kaur

Ram and disk space are irrelvant here, the configuration of a database cache size is relevant. This should be configured in a DB_CONFIG file within the database directory.
Your OS distribution may have provided a sample DB_CONFIG file.

The referenced log files document the database transactions and are vital for database operations. You may read on db_config tools and how to manage transaction logs. For more information see http://www.openldap.org/faq/data/cache/1072.html
