Planning and Configuring HP-UX DCE 2.0

Configuring HP-UX DCE Cells
Integrating DCE Services with HP Serviceguard
Chapter 6 67
Integrating DCE Services with HP
Serviceguard
HP Serviceguard provides an environment in which, if a node fails,
services (applications) can be up and running again on another node very
quickly.
This section provides background information on HP Serviceguard, and
explains detailed planning and configuration steps necessary to utilize
HP Serviceguard to increase the availability of the DCE core services.
The process and considerations provided here are also easily extended to
DCE-based application servers.
Readers of this section should already have a license for the HP
Serviceguard product and be familiar with the features and capabilities
of HP Serviceguard.
NOTE This section includes information about the HP-UX DCE server.
However, DCE Server is not available on HP-UX 11i v3. Use the
information in this section to integrate DCE 2.0 clients and older DCE
Servers (running on HP-UX 11i v1 and HP-UX 11i v2) with HP
Serviceguard.
Background
The DCE infrastructure depends on three core services, all of which are
necessary for the proper operation of a DCE Cell: the Security Service,
the Naming Service, and the Time Service. In a properly configured DCE
cell, each of these services is distributed and replicated, in order to
increase the availability and scalability of the DCE infrastructure. This
means that each service actually consists of multiple servers running on
separate hosts. Should any single server become unavailable, clients can
quickly locate and use another server (replica) that provides the same
service.
