Hi guys,
We have .net application running on the same machine as MQ server. When the application was trying to read a message from the queue we are getting the below error.
OS:Windows 2003
MQ version: 6.0.2.0
Exception in ProcessMessage: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
at IBM.WMQ.MQCommonServices.xtr_fnc_entryFn(UInt32* pCtl, UInt32 component, UInt32 module)
at IBM.WMQ.MQCommonServices.TraceEntry(String objectId, UInt32 component, UInt32 method)
at IBM.WMQ.CommonServices.TraceEntry(String objectId, UInt32 component, UInt32 method)
at IBM.WMQ.MQBaseObject.TrEntry(UInt32 method)
at IBM.WMQ.MQQueueManager.Connect(String queueManagerName)
at IBM.WMQ.MQQueueManager..ctor(String queueManagerName)
at DBMSWatcher.MQReader.ProcessMessage() |

anybody faced this issue before on windows with a .net application?. I dont see the MQ client installed though the application is still using SYSTEM.AUTO.SVRCONN channel. Do you think that could be the issue?. Do we need to install client as well when the app is using SYSTEM.AUTO.SVRCONN in connecting to Qmgr?.
Note: The MQ server and app are running on the same windows 2003 machine.
I appreciate your help on this.
Thanks. |

After how many MQGET call this issue occurs? does it occur in the very first MQGET CALL from the queue?

No it is not the issue. We are also using the .net application with same environment and MQ v6.0.2.2 and there is no this kind of issue reported till date.
You can try to apply the fix pack i.e. 6.0.2.7.
Cheers,
Aditya |

... .NET and Java both support "client-less" client connections.
That is, the .NET libraries and the Java libraries include a "native" implementation of the client interface, without requiring a full client install.
HOWEVER, with .NET, you need to *carefully* construct your client connection. I believe it has to be a managed connection, not a regular client connection.
So you may not be doing that and may require the full client install or may require adjustments to your .NET app. |
