Steps to relink oracle binary with RAC env

Execute the following on all nodes where the ORACLE_HOME exists:

1. Log in as the ORACLE_HOME owner.

2. Stop all resources (database, listener, ASM etc) that's running from the home. When stopping database, use NORMAL or IMMEDIATE option.

3. If relinking 11gR2 Grid Infrastructure home, unlock GI home as root: $GRID_HOME/crs/install/rootcrs.pl -unlock

4. Execute the following to relink:

  cd $ORACLE_HOME/rdbms/lib
  make -f ins_rdbms.mk rac_on ioracle

If interconnect is infiniband and RDS protocol is being used instead of UDP:

  cd $ORACLE_HOME/rdbms/lib
  make -f ins_rdbms.mk ipc_rds ioracle

Caution: confirm infiniband interconnect and RDS protocol before executing it
Note: If you are changing more than 1 home, repeat the make command for all homes.

5. If relinking 11gR2 Grid Infrastructure home, lock GI home as root: $GRID_HOME/crs/install/rootcrs.pl -patch
