Oracle8i Server
Oracle8i Server is the database application software and must be installed on
each node in the PDC/O1000.
Refer to the documentation provided with the Oracle8i Server software for
additional information.
Oracle8i Parallel Server Option
Oracle8i Parallel Server Option is the key component in the Oracle8i
clustering architecture. Oracle8i Parallel Server allows the database server to
divide its workload among the physical cluster nodes. This is accomplished by
running a distinct instance of Oracle8i Server on each node in the PDC/O1000.
Oracle8i Parallel Server manages the interaction between these instances.
Through its Integrated Distributed Lock Manager, Oracle8i Parallel Server
manages the ownership of database records that are requested by multiple
instances.
At a lower level, Oracle8i Parallel Server monitors cluster membership. It
interacts with the OSDs, exchanging information about the state of each
cluster node.
For additional information, refer to:
■ Oracle8i Parallel Server Setup and Configuration Guide
■ Other Oracle documentation for Oracle8i Server and Oracle8i Parallel
Server provided with the Oracle software
Oracle8i Enterprise Manager
Oracle8i Enterprise Manager is responsible for monitoring the state of both the
database entities and the cluster members. It primarily manages the software
components of the cluster. Hardware components are managed with
Compaq Insight Manager.
To conserve space for cluster resources (memory, processes), you should not
install Oracle8i Enterprise Manager on any of the PDC/O1000 cluster nodes.
Instead, it should be installed on a separate server that is running Oracle8i and
has network access to the cluster nodes. Before installing Oracle8i Enterprise
Manager, read its documentation to ensure it is installed and configured
correctly for an Oracle8i Parallel Server environment.
