Modify the file
/fmw11g/fmw1116/Middleware/wlserver_10.3/common/bin/commEnv.sh
and Change the
SUN_ARCH_DATA_MODEL="64"
JAVA_USE_64BIT=true
JAVA_HOME variable to /home/oracle/jdk1.6.0_45_64  and
JAVA_VENDOR variable to Sun.
for example ,
# Setup SUN_ARCH_DATA_MODEL
SUN_ARCH_DATA_MODEL="64"
#JAVA_USE_64BIT, true if JVM uses 64 bit operations
JAVA_USE_64BIT=true
# Reset JAVA_HOME, JAVA_VENDOR and PRODUCTION_MODE unless JAVA_HOME
# and JAVA_VENDOR are pre-defined.
if [ -z "${JAVA_HOME}" -o -z "${JAVA_VENDOR}" ]; then
  # Set up JAVA HOME
  JAVA_HOME="/home/oracle/jdk1.6.0_45_64"
  # Set up JAVA VENDOR, possible values are
  #Oracle, HP, IBM, Sun ...
  JAVA_VENDOR=Sun
  # PRODUCTION_MODE, default to the development mode
  PRODUCTION_MODE=""
