Adding a Cluster Node
Before adding a node, verify the new configuration is supported by the
PDC/O2000. To determine if your new server is supported, see the Compaq
Parallel Database Cluster Model PDC/O2000 Certification Matrix for
Windows 2000 at
www.compaq.com/solutions/enterprise/ha-pdc.html
IMPORTANT: With some possible exceptions, the servers in the cluster must be set up
identically. For example, this means using one model server for all nodes. The cluster
components common to all nodes in the cluster must be identical, for example, the
cluster interconnect adapters, amount of memory, cache, and number of CPUs must be
the same in each cluster node.
During the life of the PDC/O2000, you might need to add a new node to the
cluster. A desire to increase performance or throughput can drive this decision.
Adding another node also can increase overall availability of the system.
This can be a time-consuming and complex procedure. Be sure to read through
all of the following directions as well as those in the Oracle documentation
before starting.
Adding a new node involves the following activities:
■ Preparing the new node
■ Preparing the existing cluster nodes
■ Installing the cluster software
These subsections contain a high-level outline of the steps to follow. If you
need detailed instructions, read through Chapter 5, “Installation and
Configuration.”
