16.3 Improving Bulkload Performance
eDirectory 8.8 provides you with new options to increase the bulkload performance.
The following are the tunable parameters for bulkload performance using the Novell Import Convert
Export (ICE) utility.
•
Section 16.3.1, “eDirectory Cache Settings,” on page 504
•
Section 16.3.2, “LBURP Transaction Size Setting,” on page 504
•
Section 16.3.3, “Increasing the Number of Asynchronous Requests in ICE,” on page 505
•
Section 16.3.4, “Increased Number of LDAP Writer Threads,” on page 506
•
Section 16.3.5, “Disabling Schema Validation in ICE,” on page 506
•
Section 16.3.6, “Disabling ACL Templates,” on page 506
•
Section 16.3.7, “Backlinker,” on page 508
•
Section 16.3.8, “Enabling/Disabling Inline Cache,” on page 508
•
Section 16.3.9, “Increasing the LBURP Time Out Period,” on page 508
Also refer to the various operating system tunable parameters.
16.3.1 eDirectory Cache Settings
The most common performance hits come from poor disk I/O management and the allocation of
insufficient memory for the eDirectory cache. If eDirectory is essentially the only application, you
can set the eDirectory cache to higher values with an upper limit of 2.5 GB. All allocated cache is
eventually used. eDirectory performance on highly volatile data is improved with more cache.
You can set the cache between 100 MB and 2.5 GB. You will generally not need more than three to
four times the size of the DIB. For large DIBs, limit the cache to 2 GB.
The smallest tested cache size is 0 and the largest is 2.5 GB. Determining the proper cache size
depends on the memory needs of other processes running on the same server, and on the amount of
disk cache required. You should test a variety of cache sizes to find a good balance.
To optimize the bulkload performance, allocate a higher percentage of the eDirectory cache for
block cache. We recommend setting a value of 90%. This can be reset after the operation is
completed.
Using iMonitor is the quickest way to modify the blockcachepercentage parameter. To do so, follow
the instructions in
“Using Novell iMonitor 2.1” on page 185

.
16.3.2 LBURP Transaction Size Setting
The LBURP transaction size sets the number of records that are sent from ICE to the LDAP server
during a single transaction. Increasing this value can improve bulkload performance, assuming that
you have adequate memory and that the increase does not cause I/O contention.
