IV56612: CHANNEL MOVES TO RUNNING STATE AND PING COMPLETES ON A SENDER CHANNEL WITH TRPTYPE(TCP) AND RECEIVER CHANNEL TRPTYPE(LU62)

Fix Pack 8.0.0.1 for WebSphere MQ V8.0
Fix Pack 7.1.0.6 for WebSphere MQ V7.1

APAR status

• Closed as program error.

Error description

• On a WebSphere MQ queue manager A, a sender channel 'A.B' was
  defined with a valid IP address pointing to the queue manager B,
  a valid transmission queue and TRPTYPE set as TCP.
  
  On queue manager B, a receiver channel 'A.B' was defined with
  TRPTYPE set as LU62 and listener was defined with TRPTYPE set as
  TCP.
  
  In spite of the sender-receiver channel having different
  TRPTYPE, the channel moves into RUNNING state and the "PING
  CHANNEL" command completes successfully.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All the users who define the sender/receiver channels with a non
  default TRPTYPE.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  While accepting transmission session during communication
  establishment MQ didn't check for the TRPTYPE between the sender
  and receiver channels. The channel communication was established
  if the sender channel and the receiver side listener had the
  same TRPTYPE disregarding the receiver channel TRPTYPE.
  

Problem conclusion

• The code changes have been made to check the TRPTYPE of the
  sender/receiver before establishing the communication.
