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
3.4.1.12. 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
32K to maximum 32-bit integer (limited to the
amount of memory available on the machine)
Default Value
32K
Syntax
Integer
Example
nsslapd-db-logbuf-size: 32K
3.4.1.13. nsslapd-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 the same directory as the directory entries themselves,
/var/lib/dirsrv/
slapd-
instance_name
/db
. For fault-tolerance and performance reasons, move this log file to
another physical disk. The
nsslapd-db-logdirectory
attribute 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
Directory Server Administrator's Guide
