4.3 Hardware Requirements
Hardware requirements depend on the specific implementation of eDirectory. 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 8.8 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 Solaris.
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.
4.4 Forcing the Backlink Process to Run
Because the internal eDirectory identifiers change when upgrading to Novell eDirectory, the
backlink process must 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, start the ndstrace process by issuing the
ndstrace -l>log&
command, which runs the process at the background. You can force the backlink to run by issuing
the
ndstrace -c set ndstrace=*B
command from the ndstrace command prompt. Then
you can unload the ndstrace process by issuing the
ndstrace -u
command. Running the backlink
process is especially important on servers that do not contain a replica.
4.5 Upgrading eDirectory
If you have eDirectory 8.5. x or 8.6. x , you have to first upgrade to eDirectory 8.7 x and then upgrade
to eDirectory 8.8.
./nds-install
NOTE: Upgrade LUM to 2.1.2 if an older version is installed on the system.
