PH37919: Launch command for assisted life-cycle middleware servers runs with umask 042 rather than 022 and is not configurable.

APAR status

• Closed as program error.

Error description

• The default umask of the Intelligent Management process used
  to launch assisted life-cycle middleware servers should be
  022 rather than 042 and custom configuration of the umask
  value is not honored. This can lead to unexpected behavior
  with regards to the file permissions created by the assisted
  life-cycle servers started by Intelligent Management.
  
  For example; if a Liberty server has an environment variable
  of WLP_SKIP_UMASK set to true and has been configured for
  assisted life-cycle, the Liberty server will create
  files/directories with permissions of rw--w-r--/rwx-wxr-x
  respectively rather than rw-r--r--/rwxr-xr-x.

Problem conclusion

• The default umask of the Intelligent Management process used to
  launch assisted life-cycle middleware servers was corrected to
  022 and was made configurable.
