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.
