Forcing The Backlink Process To Run - Novell NETWARE 6-DOCUMENTATION Manual

Two factors increase performance: more cache memory and faster processors.
For best results, cache as much of the DIB Set as the hardware allows.
eDirectory scales well on a single processor. However, Novell eDirectory 8.6 takes advantage of
multiple processors. Adding processors improves performance in some areas, for example, logins
and having multiple threads active on multiple processors. eDirectory itself is not processor-
intensive, but it is I/O-intensive.
The following table illustrates typical system requirements for Novell eDirectory for Windows NT
and Windows 2000:
Objects Processor
10,000 Pentium* III 450-700 MHz (single)
1 million Pentium III 450-700 MHz (dual)
10 million Pentium III 450-700 MHz (2 to 4)
Requirements for processors might be greater than the table indicates, depending upon
additional services available on the computer as well as the number of authentications, reads,
and writes that the computer is handling. Processes such as encryption and indexing can be
processor-intensive.

Because the internal eDirectory identifiers change when upgrading to eDirectory, the backlink
process has to update backlinked objects for them to be consistent.
Backlinks keep track of external references to objects on other servers. For each external
reference on a server, the backlink process ensures that the real object exists in the correct
location and verifies all backlink attributes on the master of the replica. The backlink process
occurs two hours after the database is open and then every 780 minutes (13 hours). The interval
is configurable from 2 minutes to 10,080 minutes (7 days).
After migrating to eDirectory, we recommend that you force the backlink to run by issuing a SET
DSTRACE=*B command from the server console. Running the backlink process is especially
important on servers that do not contain a replica.
