error in XI senario: The requested application,AFW,is currently unavailable

[Former Member]

Hi Forum,

In a scenario, I have a BPM, which makes a synchronous call to R/3 for execution of a rfc enabled Function module, while doing so, it gives an error as a response, which i can see in the MONI:

<b>503 Service Unavailable

The requested application, AFW, is currently unavailable.</b>

<i><b>The same error is also thrown when the BPM makes a asynchronous connection to a database,</b></i>

can u help in diagnosing the problem, and help in rectifying it,

thanks

Hi

Just a check with this error

<i>8) Error: The error message 503 Service unavailable Application stopped! is displayed.

Description:The server is currently unable to handle the request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. If known, the length of the delay MAY be indicated in a Retry-After header. If no Retry-After is given, the client SHOULD handle the response as it would for a 500 response.

Note: The existence of the 503 status code does not imply that a server must use it when becoming overloaded. Some servers may wish to simply refuse the connection.

Possible Tips: Because of J2EE application com.sap.aii.af.ms.app not active

• Try to (re)start the application using the Visual Administrator Choose Server --> Services --> Deploy --> View on Application or restart the J2EE engine

• The problem is that not all J2EE services can be started by the J2EE. i.e Start the Visual Administrator and select Server->Services->Deploy in the tree on the left. On the right-hand side, choose the Runtime tab page. You see a tree in the right window with all applications if you select the APPLICATION radio button. Check if they are running, otherwise choose Start. Usually the J2EE engine starts all services automatically.
