Since the Oracle Disk Manager feature uses regular files, you can access these files as regular VxFS files as soon as the feature is disabled.
The steps for disabling the Oracle Disk Manager feature are the same for both 32- and 64-bit Oracle10g.
To disable the Oracle Disk Manager feature in an Oracle instance
Use the rm and ln commands to remove the link to the Oracle Disk Manager Library.
# rm ${ORACLE_HOME}/lib/libodm11.so # ln -s ${ORACLE_HOME}/lib/libodmd11.so \ ${ORACLE_HOME}/lib/libodm11.so
# rm ${ORACLE_HOME}/lib/libodm10.so # ln -s ${ORACLE_HOME}/lib/libodmd10.so \ ${ORACLE_HOME}/lib/libodm10.so
For Oracle 10g on Opteron, enter:
# rm ${ORACLE_HOME}/lib/libodm10.so # ln -s ${ORACLE_HOME}/lib/libodmd10.so \ ${ORACLE_HOME}/lib/libodm10.so
