IT09665: MCAUSER is set to '*' when all incoming users are mapped to the same user ID

APAR status

• Closed as program error.

Error description

• When running runmqsc and displaying your channel status details
  you see your channel is showing a MCAUSER as you expect:
  .
  AMQ8417: Display Channel Status details.
   CHANNEL(CHAN1.SVRCONN) CHLTYPE(SVRCONN)
   CONNAME(11.111.11.11) CURRENT
   MCAUSER(user1) STATUS(RUNNING)
   SUBSTATE(RECEIVE)
  .
  However, you notice that one of your channels has a MCAUSER
  value of '*':
  .
  AMQ8417: Display Channel Status details.
   CHANNEL(CHAN2.SVRCONN) CHLTYPE(SVRCONN)
   CONNAME(22.222.22.22) CURRENT
   MCAUSER(*) STATUS(RUNNING)
   SUBSTATE(RECEIVE)
  .
  Normally, MCAUSER(*) will appear when multiple users are
  accessing the channel at the same time; however, you have mapped
  all of your connections to one user id.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Customers with:
    multiple client channels with different users
    CHLAUTH setting MCAUSER to the same user name
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The "*" value was shown incorrectly when an MCAUSER attribute
  truncated to non-whitespace characters was compared with one
  which was space-filled, leading to the incorrect conclusion that
  the attributes were different.
  

Problem conclusion

• The MQ queue manager logic has been updated to ensure that
  truncated attributes and space padded MCAUSER attributes are
  normalized before being compared.
  
  The channel status will continue to correctly display MCAUSER(*)
  if there are multiple MCA user IDs in use on the channel
  instance.
