Enabling Oracle file mapping

 To enable Oracle file mapping with the Veritas storage mapping option

1. Ensure that the file filemap.ora exists and contains a valid entry for the Veritas mapping library for Oracle storage mapping.

   # cd $ORACLE_HOME/rdbms/filemap/etc

   # cat filemap.ora

   For 32-bit Oracle, the filemap.ora file should contain the following setting:

   lib=Veritas:/opt/VRTSdbed/lib/libvxoramap_32.so

   For 64-bit Oracle, the filemap.ora file should contain the following setting:

   lib=Veritas:/opt/VRTSdbed/lib/libvxoramap_64.so

2. After verifying that the system is using the Veritas library for Oracle storage mapping, set the file_mapping initialization parameter to true.

   SQL> alter system set file_mapping=true;

   The file_mapping initialization parameter is set to false by default. You do not need to shut down the instance to set this parameter. Setting file_mapping=true starts the FMON background process.

     Note   If you want storage mapping to be enabled whenever you start up an instance, set the file_mapping initialization parameter to true in the init.ora file.
