Resolution:
Follow the procedure mentioned below to setup in FT mode using AppManage,

1) Using AppManage utility export configuration xml file from the ear file.

    e.g. "AppManage -export -ear filenotify.ear -out filenotify.xml"


2) Edit configuration xml file and add two or more binding elements depending on number of machines application is going to be deploy.

    e.g.
                &ltbinding name="Process Archive_1">
                    &ltmachine&gthostname1</machine>
                    &ltproduct>
                        &lttype&gtbwengine</type>
                        &ltversion/>
                        &ltlocation/>
                    </product>
                    &ltdescription/>
                    &ltcontact/>
                    &ltftWeight&gt200</ftWeight>
                </binding>              


3) Each and every binding, you need to have &ltFTWeight>.  e.g.
                    &ltftWeight&gt200</ftWeight>


4)  Please set isFt to true. e.g.

            &ltisFt&gttrue</isFt>
            &ltfaultTolerant>
            &lthbInterval&gt10000</hbInterval>
            &ltactivationInterval&gt35000</activationInterval>
            &ltpreparationDelay&gt0</preparationDelay>
                </faultTolerant>


5) For advanced properties about BW process, add  &ltbwprocesses>         </bwprocesses>


6) Use appmanage to configure the application in the domain.
