Shared Storage
The storage system provides an external common
disk system accessible by all nodes of the cluster. The connection
from the nodes to the disk sub-system is usually through a fiber
switch or a SCSI connection. Once the storage volumes are presented
to the hosts in the cluster, usually with the help of the logical
volume manager, one can create volumes of suitable size for use in
the RAC database. With the introduction of ASM methodology, the
shared storage structures can be managed very easily. Once the disk
groups are created with input of the disk devices, the ASM instances
on each of the node in the cluster provide the shared storage
resources to create the Database Files. We have discussed
extensively about the preparation of storage structures in
Chapter-5, “Preparing Shared Storage”
Public Network
The clustered servers or hosts need to have public network
connectivity so that client machines in the network can access the
resources on the RAC system.
Virtual IP
Address for CRS
Oracle
10g release supports the concept of Service, which can be assigned
the Virtual IP address, and which float among the specified nodes.
By creating the Virtual IP address and Virtual Host names, the
applications get a sense of transparency in their connection to the
RAC database service. We will further examine this in later sections
of this chapter.
