Siva,
If you dont want to use Broker component it wont hurt your integration pieces (IS).Are you planning to use TN usage?
I strongly recommend to make use of IS/TN component in your architecture,it gives features that you are looking for like monitoring,resubmitting,retries,persistance and transactions maintainence/support etc…Most of the users prefer to use TN architecture in their B2B partners as well as Internal transmissions.
Please refer TN userguide documentation located in the TNConsole/doc folder or download from the webMethods Advantage site.
Just few thoughts.
HTH,
