IT28500: FDC with Probe Id RM680065 and AMQ9504E Error are reported when a Java or managed .NET client issues an object inquiry

APAR status

• Closed as program error.

Error description

• A Java or managed .NET client application receives
  MQRC_CONNECTION_BROKEN when it connects to a V9.1 Queue Manager.
  The same application would function normally when connecting to
  a Queue Manager at a level lower than MQ V9.1
  
  On the MQ Server, a failure data capture (FDC) record is
  generated, with the following Probe Id, Component, and Function
  Stack:
  
  Probe Id          :- RM680065
  Component         :- rriBadDataReceived
  Program Name      :- amqrmppa
  Major Errorcode   :- rrcE_PROTOCOL_ERROR
  Probe Description :- AMQ9504E: A protocol error was detected for
                       channel 'Channel_Name'.
  Arith1            :- 125 (0x7d)
  Arith2            :- 116 (0x74)
  Comment1          :- Channel_Name
  
  The error occurs when the application sends an MQINQ call where
  the provided IntAttrCount parameter is greater than the provided
  SelectorCount parameter.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Java and fully managed .NET clients that call inquire() or
  MQINQ() methods are potentially affected, based on the
  parameters passed.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The MQ 9.1 SVRCONN channel agent incorrectly produces a protocol
  error FDC record if the passed IntAttrCount parameter is greater
  than the passed SelectorCount parameter, in previous releases
  the SVRCONN agent would attempt to process the inquiry request.
  

Problem conclusion

• The code has been updated so that the inquiry request is
  processed the same as in previous releases of the MQ server.
