Problem summary
**************************************************************** USERS AFFECTED: All users of IBM Integration Bus using the Aggregation Nodes. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: In the Aggregate Reply node, if a failure occurs when writing messages to the AggregateReply queue then a stranded message can be left on the Aggregate Request queue. If the "Unknown Message Timeout" property on the AggregateRequest Node is set to anything other than 0 then these messages will be cleaned up automatically. There are a number of resource name changes between WebSphere Message Broker and IBM Integration Bus Version 9.0. For details visit http://pic.dhe.ibm.com/infocenter/wmbhelp/v9r0m0/topic/com.ibm.e tools.mft.doc/bb23814_.htm
Problem conclusion
An environment variable MQSI_AGGR_REQUEST_TIMEOUT_FACTOR has been introduced. When set to a positive integer this sets the expiry on the internal aggregate request messages to this multiple of the aggregation expiry. So for example if the aggregation timeout is set to 10 seconds and the aggregate request timeout factor is set to 5 then the request messages will have an expiry of 50 seconds. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v10.0 10.0.0.8 v9.0 9.0.0.8 The latest available maintenance can be obtained from: http://www-01.ibm.com/support/docview.wss?rs=849&uid=swg27006041 If the maintenance level is not yet available,information on its planned availability can be found on: http://www-1.ibm.com/support/docview.wss?rs=849&uid=swg27006308 ---------------------------------------------------------------
