IT32659: IgnoreSeqNumberMismatch writes an AMQ9703 error for each message

APAR status

• Closed as program error.

Error description

• Enabling IgnoreSeqNumberMismatch allows a channel to start if it
  has a sequence number mismatch. However, the AMQ9703 error
  message is generated for each message received on the receiver
  side.

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users using the IgnoreSeqNumberMismatch tuning parameter
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  There was a defect in the MQ code which implements the
  IgnoreSeqNumberMismatch feature, such that it did not store the
  altered sequence number.  This caused
  the AMQ9703 error message to be generated for each message
  received on the receiver side.
  

Problem conclusion

• The MQ code has been corrected to store the altered sequence
  number, and generate AMQ9703 error message only once.
  
  Changes to MQ documentation:
  
  The tuning parameter IgnoreSeqNumberMismatch needs to be set on
  the receiver queue manager.
