IT44412: Enhancements to the modver utility

APAR status

• Closed as program error.

Error description

• The IBM MQ Replicated Data Queue Manager (RDQM) component
  includes a utility called "modver" which can be used to
  determine the appropriate kernel module for the current kernel.
  
  This APAR delivers some modifications to this utility.

Problem conclusion

• New optional parameters have been added to the modver utility.
  The new parameters allow a kernel level other than the current
  kernel to be checked. A minimum MQ level is optionally reported.
  
  The usage description is:
  
  
  modver [ -?|-h | ( [-m|-M] [-v] [kernelLevel] ) ]
      -?|-h : Show usage text and exit
      -m :    Print the minimum IBM MQ maintenance level
  compatible with the appropriate kernel module kernel level
      -M :    Only print the minimum compatible IBM MQ maintenance
  level, do not print the kernel module
      -v :    Print verbose output
      kernelLevel  A RHEL kernel level to test. If omitted the
  currently running kernel level returned by 'uname -a' is used
  
  
  This APAR additionally introduces the modver utility for future
  IBM MQ 9.1 maintenance releases and the associated IBM MQ 9.1
  kernel module download package.
  
  ---------------------------------------------------------------
