IT16297: dspmqver hangs if mqinst.ini contains comment or blank lines

APAR status

• Closed as program error.

Error description

• MQ 8.0 dspmqver hangs when running by user or when invoked
  indirectly by utilities such as rpm in Linux.
  .
  There are no FDC files, no error messages.
  .
  Upon further investigation, it was found that the there was an
  extra blank line at the end of the MQ installation ini file:
  /etc/opt/mqm/mqinst.ini
  .
  After removing the extra blank line, then dspmqver worked fine
  and the rpm command in Linux was able to work fine too. This
  problem might
  also occur if there is a comment line instead of a blank line.
  
  Examples:
  
  Primary:
     <blank line>
     Name=Installation16
  
  Primary:
     Name=Installation16
    <blank line>
  
  Primary:
    #comment
     Name=Installation16
  
  Primary:
     Name=Installation16
       #comment
  
  Other MQ commands - setmqinst, dspmqinst, dspmq (dspmq -o all) -
  are also affected by this problem.
  

Local fix

• Check if there is an extra blank line at the end of the file:
    /etc/opt/mqm/mqinst.ini
  If affirmative, remove it. Then try dspmqver or rpm again.
