The default transaction size is 25, which is appropriate for small LDIF files (fewer than 100,000
operations) but not for a large number of records. The LBURP transaction size can be set between 1
and 350.
Modifying the Transaction Size
To modify the transaction size, modify the required value for the n4u.ldap.lburp.transize parameter
in
/etc/opt/novell/eDirectory/conf/nds.conf
. In ideal scenarios, a higher
transaction size ensures faster performance. However, the transaction size must not be set to
arbitrarily high values for the following reasons:
• A larger transaction size requires the server to allocate more memory to process the transaction.
If the system is running low on memory, this can cause a slowdown due to swapping.
• The LDIF file should be free of errors and any entries already existing in eDirectory should be
commented out. Even if a single error exists in the transaction (including cases where the object
to be added already exists in the directory), eDirectory ignores the LBURP transaction setting
and performs a commit after each operation to ensure data integrity.
See “
Debugging LDIF Files ” for more information.
• LBURP optimization works only for leaf objects. If the transaction contains both a container
and its subordinate objects, eDirectory treats this as an error. To avoid this, we recommend
loading the container objects first using a separate LDIF file or enables the use of forward
references.
See “
Enabling Forward References ” in the Novell eDirectory 8.8 Troubleshooting Guide for
more information.
16.3.3 Increasing the Number of Asynchronous Requests in
ICE
This refers to the number of entries the ICE client can send to the LDAP server asynchronously
before waiting for any result back from the server.
The number of asynchronous requests can be set between 10 and 200. The default value is 100. Any
value less than the minimum value (10) would fallback to the default. The minimum value is
appropriate for small LDIF files.
In ideal scenarios, a higher window size ensures faster performance. However, the window size
must not be set to arbitrarily high values because a larger window size requires the client to allocate
more memory to process the entries in the LDIF file. If the system is running low on memory, this
can cause a slowdown due to swapping.
You can modify the number of asynchronous requests in ICE using either the ICE command line
option or iManager.
Using ICE Command Line Option
The number of asynchronous requests can be specified using the ICE command line option -Z. This
is available as part of the LDAP destination handler.
To set the number of asynchronous requests sent by the ICE client to 50, you would enter the
following command:
