Can someone give me sample or link of db polling ?

1. created db adapter with logical delete option
2. then created bpel process based on wsdl
i tired inserting new data but my instance did not get executed?
Can you please specify your requirement in more detail so I can understand why you need to DB adapter.
Inbound vs Outbound:
The main function of inbound is to execute a sql select query and turn the result set as a message. This in relation to outbound that handles a message to execute an SQL query.
Don't worry about this with the DB adapter as it will do this for you. The only thing you have to make sure that the JNDI name you specify in the DB adapter is configured as a data source in weblogic.
