12.5.3 Setting Up OpenSLP on OES 2 Networks
SLP services are always installed as part of both NetWare and SLES 10 SP3 (the underlying OES 2
SP3 platform). On NetWare the Novell SLP service is configured to automatically work with
eDirectory and other services. On OES 2, the OpenSLP service must be manually configured to
work with eDirectory and other services.

When Is OpenSLP Required?
You must set up OpenSLP on your OES 2x server if both of the following apply:

You plan to install more than three servers into a new tree or a new eDirectory partition being
created on an OES 2 server.

You either don’t have an existing Novell SLP service, or you don’t want to continue using
Novell SLP.
Differences Novell SLP directory agents (DAs) store
service registrations for their SLP scope
in eDirectory.
As a new service registration is stored in
eDirectory, other DAs assigned to the
same scope are notified so that they can
refresh their caches with the latest
service information.
Also, when a Novell SLP DA starts up, it
immediately populates its cache with the
latest service information stored in
eDirectory.
NOTE: Novell SLP DAs do not directly
share information with each other as
many administrators have assumed. But
they do maintain well synchronized
caches through eDirectory as described
above.
OpenSLP directory agents (DAs) are
completely separate and have no way to
initially populate or refresh their service
information the way Novell SLP DAs do.
A DA’s cache is empty when it starts up and
is populated only as services register
themselves.
Compatibility Novell SLP user agents (UAs) or service
agents (SAs) can access both Novell
SLP DAs and OpenSLP DAs. OpenSLP-based user agents or service
agents can access both Novell SLP DAs
and OpenSLP DAs.
