J2CA0056I

Exceptions that the IMS TM resource adapter throws can be caught by a component other than your Java™ application, such as the WebSphere® Application Server.

For example, when WebSphere Application Server catches an exception from your Java application, it might then issue its own message, including in it the message from the IMS TM resource adapter exception. For example, when execution timeout occurs, you see the following message on the WebSphere Application Server console:


J2CA0056I: The Connection Manager received a fatal connection error
from the
Resource Adaptor for resource myConnFactry.  The exception which
was received is
ICO0080E:
com.ibm.connector2.ims.ico.IMSTCPIPManagedConnection@e59583c.
processOutputOTMAMsg(byte[],IMSInteractionSpec, int) error. 
Execution timeout has occurred for this interaction.
The executionTimeout was [0] milliseconds.  The IMS Connect TIMEOUT
was used.

J2CA0056I is an informational message from WebSphere Application Server. The fatal connection error occurs because IMS Connect closes the socket when an execution times out, and the WebSphere Application Server Connection Manager removes the connection object for the socket from the connection pool.

Another example occurs when a transaction (non-persistent) socket is used for a commit mode 0 interaction. In this case, you see the following message on the WebSphere Application Server console:

J2CA0056I: The Connection Manager received a fatal connection error
from the
Resource Adaptor for resource  myConnFactry.  The exception which
was received is ICO0089I:
com.ibm.connector2.ims.ico.IMSTCPIPManagedConnection@6db5d83a.call(Connection,
InteractionSpec, Record, Record). Non-persistent socket closed for
Commit Mode 0 IMS transaction.
