IT30754: The MQ fix pack installer incorrectly reports resources in use when an authority error is encountered

APAR status

• Closed as program error.

Error description

• An error was seen when installing an MQ Fix Pack:
  
    WebSphere MQ shared resources associated with the
    installation at '/xxx/xxxxxx/xxxx/xxx' are still
    in use. You must stop all MQ processes, including
    applications, Queue Managers, and Listeners, before
    attempting to install, update or delete the WebSphere
    MQ product.
  
  
  But the debug.out file shows:
  
    amqiclen -v -x return code was: '243', output was:
    Failed while executing the mqm.server.rte.pre_u script
  
  243 in decimal is 0xf3 in hex. This is a truncated (single-byte)
  version of 0x7f3, which in decimal is 2035
  (MQRC_NOT_AUTHORIZED).
  
  Therefore the output saying "shared resources associated ... are
  still in use" is not a correct statement of the root cause of
  the problem.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users upgrading or installing IBM MQ, in the rare case where
  there is a problem encountered during installation.
  
  
  Platforms affected:
  AIX, Linux on S390, Linux on x86-64, Linux on zSeries, Solaris
  SPARC, Solaris x86-64, Linux on Power
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  There are places in the installer code where amqiclen is run
  (this is an internal MQ program that runs as part of
  installation/uninstallation).
  
  In most cases this means that shared memory segments are still
  in use by running queue managers or their applications.
  
  But in other (rare) cases where there is some other reason for
  the program to fail, the error text should be different, so as
  not to be misleading.
  

Problem conclusion

• The MQ installer/uninstaller code has been updated to output
  error text that is appropriate to the failure.
