IC72986: The WebSphere MQ user defined queue manager service does not stop a program if the STDOUT parameter is not set

WebSphere MQ V7.0 Fix Pack 7.0.1.5
WebSphere MQ V7.0.1 for i5/OS Fix Pack 7.0.1.5

APAR status

• Closed as program error.

Error description

• A WebSphere MQ queue manager service is defined to
  start and stop a .cmd or .bat file, using the default
  value for the STDOUT parameter which is blank.
  
  Starting the service shows:
  AMQ8733: Request to start Service accepted.
  The program being started by the service is started
  as expected.
  
  Stopping the service appears to work:
  AMQ8732: Request to stop Service accepted.
  Upon further review, the program being stopped by the
  service is still running.
  
  ADDITIONAL KEYWORDS
  SERVICE STARTCMD STOPCMD
  

Local fix

• In MQ we create a new process to stop the program
  provided in the STOPCMD parameter of the Service. If STDOUT or
  STDERR is not set the creation flag for the new process is
  DETACHED_PROCESS and this new process does not execute the
  contents of the .cmd or .bat file. The fix for the defect
  modifies the process creation flag in zxpStopProcess function to
  use CREATE_NO_WINDOW if the program to be stopped is a .cmd or
  .bat file and if the output and error file handle is NULL.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Any users of WebSphere MQ using service object definitions to
  launch batch files (.cmd and .bat).
  
  Platforms affected:
  Windows
  
  ****************************************************************
  PROBLEM SUMMARY:
  WebSphere MQ launches the program provided in the STOPCMD
  parameter of the Service when the stop service is executed.
  However,  the STOPCMD fails to launch batch files ( .bat
  or .cmd) if the default values for STDOUT/STDERR is specified;
  in other words if the STDOUT/STDERR is not set.
  

Problem conclusion

• The problem was caused by the fact that WebSphere MQ was
  specifying incorrect options on the CreateProcess call when
  launching a batch file. The WebSphere MQ code has been modified
  to alter the flag passed to the CreateProcess call if the
  program to be started is a .bat or .cmd file.
