Installing or Upgrading Novell eDirectory on HP-UX 99novdocx (en) 6 April 2007Configuring Static IP AddressRefer to “Configuring Static IP Address” on page 12 for more information on configuring static IPaddresses.6.3 Hardware RequirementsHardware requirements depend on the specific implementation of eDirectory. Two factors increaseperformance: more cache memory and faster processors. For best results, cache as much of the DIBSet as the hardware allows.eDirectory scales well on a single processor. However, Novell eDirectory 8.8 takes advantage ofmultiple processors. Adding processors improves performance in some areas—for example, loginsand having multiple threads active on multiple processors. eDirectory itself is not processorintensive, but it is I/O intensive.The following table illustrates typical system requirements for Novell eDirectory for HP-UX.Requirements for processors might be greater than the table indicates, depending upon additionalservices available on the computer as well as the number of authentications, reads, and writes thatthe computer is handling. Processes such as encryption and indexing can be processor intensive.6.4 Forcing the Backlink Process to RunBecause the internal eDirectory identifiers change when upgrading to Novell eDirectory, thebacklink process must update backlinked objects for them to be consistent.Backlinks keep track of external references to objects on other servers. For each external referenceon a server, the backlink process ensures that the real object exists in the correct location and verifiesall backlink attributes on the master of the replica. The backlink process occurs two hours after thedatabase is open, and then every 780 minutes (13 hours). The interval is configurable from 2minutes 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 issuingthe ndstrace -c SET DSTRACE=*B command from the ndstrace command prompt. Then youcan unload the ndstrace process by issuing the ndstrace -u command. Running the backlinkprocess is especially important on servers that do not contain a replica.6.5 Upgrading eDirectoryYou can upgrade to eDirectory 8.8 either through the nds-install utility or the swinstall utility.Objects Processor Memory Hard Disk100,000 PA-RISC 2.0 384 MB 144 MB1 million PA-RISC 2.0 2 GB 1.5 GB10 million PA-RISC 2.0 2+ GB 15 GB
