Error description

• When setting a non-default umask incorrect file permissions
  may be assigned during file creation.
  WebSphere Application Server for z/OS V8 servers create temp
  files with unexpected and incorrect file permissions if the
  server's environment variable _BPX_BATCH_UMASK is supplied with
  a value greater than the default of 007.
  
  If the server's _BPX_BATCH_UMASK variable is set to something
  other than 007, then the server's file creation umask will be
  set to the decimal equivalent value, instead of the octal value
  that it should be set to.
  For example: A _BPX_BATCH_UMASK of 007 will yield  the expected
  umask of 007.  However a _BPX_BATCH_UMASK of 022 will yield an
  actual process umask value of 016, which is not correct.
  
  If your server is  generating temporary files with unusual or
  unexpected permission bits turned on or off, check to see if the
  environment variable _BPX_BATCH_UMASK has been specified with a
  value greater than 007.

  When setting a custom umask the server may be assigned an
  incorrect umask setting. This may result in incorrect
  permission bits on files created by the server.
  

Problem conclusion

• The code has been changed to correct the algorithm used to
  convert the specified umask to the required internal bitmap
  format.
  
  APAR PM47305 is currently targeted for inclusion in
  Service Level (8.0.0.2)  of WebSphere Application Server.
