Oracle Disk I/O Tuning
Chapter 5: Cluster File System
For example, we may want to keep a local
tnsnames.ora file or a local listener.ora file. For the purpose of
setting up Intelligent Agent, we may want to separate the $ORACLE_HOME/network
directory from the shared Oracle home installation without having to
physically install the Intelligent Agent on each node in the
cluster. In such situations, setting up a context dependent symbolic
link (CDSL) creates a node-dependent copy of the file or directory.
There are many cluster file system
products that can be used for building the RAC system. They include:
Tru64 CFS for HP/Compaq Cluster servers, Veritas CFS for Solaris
based RAC Clusters, PolyServe Matrix Server for Linux and Windows
based RAC Clusters, and Oracle cluster files systems for Linux and
Windows RAC clusters. Let us examine some of the important features
of these products. Only some of these, however, support CDSL.
