HP UX Identity Security Software manual 137

Before modifying the value of this attribute, export all databases using the db2ldif script. After the modification has been made, reload the databases using the ldif2db script.

CAUTION:

This parameter should only be used by very advanced users.

Parameter	Description
Entry DN	cn=config, cn=ldbm database, cn=plugins, cn=config
Valid Range	0 to 8
Default Value	0
Syntax	Integer
Example	nsslapd-db-idl-divisor: 2

3.4.1.11 nsslapd-db-logbuf-size

This attribute specifies the log information buffer size. Log information is stored in memory until the buffer fills up or the transaction commit forces the buffer to be written to disk. Larger buffer sizes can significantly increase throughput in the presence of long running transactions, highly concurrent applications, or transactions producing large amounts of data. The log information buffer size is the transaction log size divided by four.

The nsslapd-db-logbuf-size attribute is only valid if the nsslapd-db-durable-transactions attribute is set to on.

Parameter	Description
Entry DN	cn=config, cn=ldbm database, cn=plugins, cn=config
Valid Range	32768 to the maximum 32-bit integer. Any specified value below the minimum is
	automatically adjusted to the minimum value.
Default Value	0 (automatically adjusted to 32768)
Syntax	Integer
Example	nsslapd-db-logbuf-size: 32K

3.4.1.12nsslapd-db-logdirectory

This attribute specifies the path and directory name of the directory containing the database transaction log. The database transaction log contains a sequential listing of all recent database operations and is used for database recovery only. By default, the database transaction log is stored in /var/opt/dirsrv/slapd-instance_name/dbalong with the database files themselves. For fault-tolerance and performance reasons, move this log file to another physical disk. The nsslapd-db-logdirectoryattribute is absent from dse.ldif. To change the location of the database transaction log, add the attribute to dse.ldif.

For more information on database transaction logging, refer to the "Monitoring Server and Database Activity" chapter in the HP-UX Directory Server administrator guide.

Parameter	Description
Entry DN	cn=config, cn=ldbm database, cn=plugins, cn=config
Valid Values	Any valid path and directory name
Default Value
