Unlinking the Oracle binary from Veritas libraries

If you uninstalled Oracle9i, proceed to stop VCS. Otherwise, unlink the Veritas libraries.

See Stopping VCS

 To unlink the Veritas libraries

1. Log in as oracle user.
2. Using vi or another text editor, open the init$ORACLE_SID.ora file.

   $ cd $ORACLE_HOME/dbs/

   $ vi init$ORACLE_SID.ora

3. Set the cluster_database parameter to FALSE in the init$ORACLE_SID.ora file.

   cluster_database=FALSE

4. Navigate to the following directory:

   $ cd $ORACLE_HOME/lib

5. Link the original ODM library file to remove the Veritas ODM function.

    

   PA systems	$ ln -s $ORACLE_HOME/lib/libodmd9.sl \ $ORACLE_HOME/lib/libodm9.sl
   IA systems	$ ln -s $ORACLE_HOME/lib/libodmd9.so \ $ORACLE_HOME/lib/libodm9.so

6. To convert from Oracle RAC binary to Oracle single-instance binary, enter:

   $ cd $ORACLE_HOME/rdbms/lib

   $ make -f ins_rdbms.mk rac_off

   $ make -f ins_rdbms.mk ioracle

7. If $ORACLE_HOME is located on the file systems of the local nodes, perform step 1 through step 6 on each of the other nodes.
8. To verify the state of the Oracle RAC configuration, type:

   $ ldd $ORACLE_HOME/bin/oracle | egrep "lltdb|vcsmm"

9. Review the output of the command that you executed to verify the state.
   • If the command does not generate output, then Oracle single-instance binary is configured successfully.
   • If the command generates the following output, then Oracle RAC is still enabled.

      

     PA systems	/usr/lib/pa20_64/libvcsmm.1 => /usr/lib/pa20_64/libvcsmm.1 /usr/lib/pa20_64/liblltdb.1 => /usr/lib/pa20_64/liblltdb.1
     IA systems	/usr/lib/hpux64/libvcsmm.1 => /usr/lib/hpux64/libvcsmm.1 /usr/lib/hpux64/liblltdb.so.1 => /usr/lib/hpux64/liblltdb.so.1

     You might have to redo the unlinking task to configure the Oracle single-instance binary.
