The nsslapd-db-checkpoint-interval attribute is absent from dse.ldif. To change the
checkpoint interval, add the attribute to dse.ldif. This attribute can be dynamically modified using
ldapmodify. For further information on modifying this attribute, see the "Tuning Directory Server
Performance" chapter in the Directory Server Administrator's Guide.
This attribute is provided only for system modification/diagnostics and should be changed only with the
guidance of Red Hat technical support or Red Hat professional services. Inconsistent settings of this
attribute and other configuration attributes may cause the Directory Server to be unstable.
For more information on database transaction logging, refer to the "Monitoring Server and Database
Activity" chapter in the Directory Server Administrator's Guide.

This attribute specifies circular logging for the transaction log files. If this attribute is switched off, old
transaction log files are not removed and are kept renamed as old log transaction files. Turning circular
logging off can severely degrade server performance and, as such, should only be modified with the
guidance of Red Hat Technical Support or Red Hat Professional Services.
