Planning Your OES 2 Implementation 41
3.9.13 Installing into an Existing eDirectory Tree
Novell Support has reported a significant number of installation incidents related to eDirectory
health and time synchronization. To avoid such problems, do the following prior to installing OES:

“Consider Coexistence and Migration Issues” on page 41

“Do Not Add OES to a Server That Is Already Running eDirectory” on page 41

“Be Sure That eDirectory Is Healthy” on page 41

“Be Sure That Network Time Is Synchronized” on page 41

“Be Sure that OpenSLP on OES 2 Is Configured Properly” on page 41
Consider Coexistence and Migration Issues
If you are installing a new OES 2 server into an existing eDirectory tree, be sure to read and follow
the instructions in “
Preparing eDirectory for OES 2 SP3 ” in the OES 2 SP3: Installation Guide .
Do Not Add OES to a Server That Is Already Running eDirectory
Although you can add OES to an existing SLES 10 server if needed, you cannot install OES on a
SLES 10 server that is already running eDirectory.
eDirectory must be installed in conjunction with the installation of OES services.
Be Sure That eDirectory Is Healthy
Review and follow the guidelines in “ Keeping eDirectory Healthy ” in the Novell eDirectory 8.8
Administration Guide .
Be Sure That Network Time Is Synchronized
OES2 Linux and NetWare 6.5 SP8 servers can receive network time from either an existing
eDirectory server or from an NTP time source. The critical point is that the entire tree must be
synchronized to the same time source. For example, do not set your new OES 2 server to receive
time from an NTP source unless the whole tree is synchronized to the same NTP source.
For an in-depth explanation of OES time synchronization, see Chapter 12.3, “Time Services,” on
page 99 .
Be Sure that OpenSLP on OES 2 Is Configured Properly
Novell SLP (NetWare) and OpenSLP (Linux) can coexist, but there are differences between the
services that you should understand before deciding which to use or before changing your existing
SLP service configuration. For more information, see
Section 12.5, “SLP,” on page 111 .
