Veritas has defined and implemented two libraries: libvxoramap_64.so and libvxoramap_64.sl. These two libraries provide a mapping interface to Oracle9i release 2 or later. libvxoramap_64.so serves as a bridge between Oracle's set of storage APIs (known as "ORAMAP") and Veritas Federated Mapping Service (VxMS), a library that assists in the development of distributed SAN applications that must share information about the physical location of files and volumes on a disk.
With VERITAS Storage Foundation for Oracle storage mapping option, you can view the complete I/O topology mapping of datafiles through intermediate layers like logical volumes down to actual physical devices. This information can be used to determine the exact location of an Oracle data block on a physical device and to help identify hot spots.
Note
To use the mapping functionality, you must be using Oracle 9.2.0.3 or later.
