HP-UX Directory Server 8.1 configuration, command, and file reference

3.4.1.24 nsslapd-idlistscanlimit
This performance-related attribute, present by default, specifies the number of entry IDs that are
searched during a search operation. Attempting to set a value that is not a number or is too big
for a 32-bit signed integer returns an LDAP_UNWILLING_TO_PERFORM error message, with
additional error information explaining the problem.
It is advisable to keep the default value to improve search performance. For a more detailed
explanation of the effect of ID lists on search performance, refer to the "Managing Indexes" chapter
in the HP-UX Directory Server administrator guide.
The server has to be restarted for changes to this attribute to go into effect.

3.4.1.25 nsslapd-import-cachesize
This performance tuning-related attribute determines the size of the database cache used in the
bulk import process. Setting this attribute value so that the maximum available system physical
memory is used for the database cache during bulk importing optimizes bulk import speed.
Attempting to set a value that is not a number or is too big for a 32-bit signed integer returns an
LDAP_UNWILLING_TO_PERFORM error message, with additional error information explaining
the problem.
NOTE:
A cache is created for each load that occurs. For example, if the user sets the
nsslapd-import-cachesize attribute to 1 gigabyte, then 1 gigabyte is used when loading
one database, 2 gigabytes is used when loading two databases, and so on. Ensure there is sufficient
physical memory to prevent swapping from occurring, as this would result in performance
degradation.
DescriptionParameter
cn=config, cn=ldbm database, cn=plugins, cn=configEntry DN
500 kilobytes to 4 gigabytes for 32-bit platforms and 500 kilobytes to 2^64-1 for 64-bit

3.4.1.26 nsslapd-import-cache-autosize
This performance tuning-related attribute automatically sets the size of the import cache
(importCache) to be used during the command-line-based import process of LDIF files to the
database (the ldif2db operation).
In Directory Server, the import operation can be run as a server task or exclusively on the
command-line. In the task mode, the import operation runs as a general Directory Server
operation. The nsslapd-import-cache-autosize attribute enables the importCache to
