Setting up Veritas Extension for Oracle Disk Manager

Veritas Extension for Oracle Disk Manager is part of Veritas Storage Foundation for Oracle. Veritas Extension for Oracle Disk Manager is enabled once Veritas Storage Foundation for Oracle and Oracle9i or later are installed, and the Veritas Extension for Oracle Disk Manager library is linked to the library in the {ORACLE_HOME}/lib directory.

If you are performing a local Oracle installation, not on the SFCFS file system, then ODM linking needs to be performed on all nodes in the cluster.

Before setting up Veritas Extension for Oracle Disk Manager, the following conditions must be met:

Prerequisites

  • Veritas Storage Foundation for Oracle must be installed on your system.

  • Oracle9i, or later, must be installed on your system.

  • If Cached Quick I/O is available, do not enable Oracle Disk Manager when Cached Quick I/O is enabled for datafiles. (Cached Quick I/O is not available on Linux.)

Usage Notes

  • When the Quick I/O feature is available, Oracle Disk Manager uses the Quick I/O driver to perform asynchronous I/O. Do not turn off the Quick I/O mount option, which is the default. (Quick I/O is not available on Linux.)

  • Oracle uses default file access methods if Oracle9i or later or Veritas Storage Foundation for Oracle is not installed, or VxFS 5.0 is not available in the kernel.
