Disabling the Oracle Disk Manager feature

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.

Note:

To convert to VxFS with Quick I/O, disable Oracle Disk Manager using the following procedure, then convert the files to Quick I/O files.

Before disabling the Oracle Disk Manager feature, you may want to back up your files.

To disable the Oracle Disk Manager feature in an Oracle instance

  1. Shut down the database instance.
  2. Use the rm and ln commands to remove the link to the Oracle Disk Manager Library.

    For Oracle 11g, enter:

    # rm ${ORACLE_HOME}/lib/libodm11.so
# ln -s ${ORACLE_HOME}/lib/libodmd11.so \
${ORACLE_HOME}/lib/libodm11.so

    For Oracle 10g, enter:

    # 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
  3. Restart the database instance.
