Improving Bulkload Performance; Edirectory Cache Settings - Novell EDIRECTORY 8.8 SP5 - ADMINISTRATION Administration Manual

The new costing is very dynamic and changes very frequently. In order to watch it work, you can set
the Advanced Referral Costing parameter to Debug mode.
NOTE: Ensure you reset ARC to non debug mode, i.e. set NDSTRACE = !ARC1 when you have
finished monitoring. Overhead printing costs are not desirable when you don't need it.
In the DSTrace or NDSTrace, you now see the individual referral costs displayed if Advanced
Referral Costing and +RSLV are turned on. The remaining tags are turned off using
set NDSTrace =nodebug
Sorted results from DCAdjustCostAndSort follow:
137.65.10.3 cost of 217
137.65.10.9 cost of 222
137.65.10.10 cost of 400
The numbers change quickly if a remote server is slow or overloaded. The ExRef server's costing
adjusts dynamically every second, so to watch costs over time you should the trace to a log file.

To optimize the bulkload performance, allocate a higher percentage of the eDirectory cache for
block cache.
