Database Plug-in Attributes

Netscape Directory Server Configuration, Command, and File Reference • December 2001
nsslapd-db-idl-divisor
Specifies the index block size in terms of the number of blocks per database page.
The block size is calculated by dividing the database page size by the value of this
attribute. A value of 1 makes the block size exactly equal to the page size. The
default value of 0 sets the block size to the page size minus an estimated allowance
for internal database overhead.
nsslapd-db-logbuf-size
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 signficantly increase throughput in the presence of long
running transactions, highly concurrent applications, or transactions producing
large amounts of data.
NOTE
Before modifying the value of this attribute export all databases
using the
db2ldif
script. Once the modification has been made,
reload the databases using the
ldif2db
script.
