the message is not reaching the outgoing communication channel

hi forum help..............

i have a IDOC -XI --JDBC scenario...

my xi receives an idoc from a sap ecc.....does a simple mapping to a jdbc structuuure and then writes to a databse....

it was working fine..... but now i had to change the JDBC adapter configuration..means in the integration builder(configuration).. i changed the name of my database server.....

now after making that change ....... the message is not reaching the outgoing communication channel....

i cant see any error in the sxmb_moni....

but there is no log for the message processing in the communication channel in the RWB............
