Error description
When problems occur in the TCP/IP networking environment the WMQFTE agent may appear as if it is hung. In actuality, the problem occurs because the MQ Channel is attempting to reconnect to its queue manager. A timing issue in the code occurs when the negotiation between 2 agents is taking too long.
Local fix
On any agent that is acting as the source of a transfer, set maxTransferNegotiationTime=300000 in the agent.properties file. This increases the timeout to wait for the negotiation message from the other agent in the transfer from 30s to 5m.
Problem summary
This problem can occur when a transfer is in a resynchronising state due to the initial negotiation timing out and a notification is received from the destination while the sender is processing the command response message. The exception is thrown because the processsing of the command message has read the state from the persistent store under syncPoint which has not yet been committed when then notification is received. USERS AFFECTED: Those with slow or unreliable networks PLATFORMS AFFECTED: All
Problem conclusion
The FTEStateStoreImpl notifyAcknowledgement method has been updated to ignore WMQApiFailureExceptions if the reason code is MQRC_NO_MSG_AVAILABLE
Temporary fix
No iFix available - Fixed in fixpack 7.0.2.1
