Unlinking the Oracle Binary From VERITAS Libraries

If you uninstalled Oracle9i, proceed to Stopping VCS. Otherwise, unlink the VERITAS libraries:

1. Log in as the oracle user.
2. Using vi or another text editor, edit the init$ORACLE_SID.ora file:
     $ cd $ORACLE_HOME/dbs/
     $ vi init$ORACLE_SID.ora

   Set the cluster_database parameter to FALSE:

   
     cluster_database=FALSE
3. Navigate to the following directory:
     $ cd   $ORACLE_HOME/lib
4. Remove the file linked to the VERITAS ODM library.

   For PA systems:

   
     $ rm $ORACLE_HOME/lib/libodmd9.sl

   For IA systems:

   
     $ rm $ORACLE_HOME/lib/libodmd9.so
5. Copy the original ODM library file to remove the Veritas ODM function.

   For PA systems:

   
   $ cp $ORACLE_HOME/lib/libodmd9.sl.oracle
   $ORACLE_HOME/lib/libodmd9.sl

   For IA systems:

   
   $ cp $ORACLE_HOME/lib/libodmd9.so.oracle
   $ORACLE_HOME/lib/libodmd9.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"
   • Oracle single-instance binary is configured if the command does not generate output.
   • Oracle RAC is enabled if the following output appears.

   For 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

   For IA systems:

   
       /usr/lib/hpux64/libvcsmm.1 =>   /usr/lib/hpux64/libvcsmm.1
   /usr/lib/hpux64/liblltdb.so.1 => /usr/lib/hpux64/
   liblltdb.so.1
