Abstract

In a complex, multiple node, distributed environment, an absolute file name link must be recoverable to a directory tree other than that from which the file link originated without requiring manual intervention.

Dynamic Path Naming Resolution Heuristic

      In a complex, multiple node, distributed environment, an
absolute file name link must be recoverable to a directory tree other
than that from which the file link originated without requiring
manual intervention.

      A methodology is defined which allows the recovery of a link to
an individual file without restriction to a parent node or to the
original 'file state' directory tree.

      In a UNIX*-based environment, objects (files) which are shared
by multiple users will be referenced by absolute address as well as
by indirect addressing (a link is an example of this).  Because this
is part of the state information for a file recovery, there are
instances in which the 'node absolute filename' information is
fundamental to the recovery, and other instances where this state
information is restrictive to that recovery.

      The methodology first resolves the link for a file.  If the
link base (the actual file) is not accessible from the node which is
driving the recovery, the function attempts to recover the actual
file to the current directory.  The file state information (links and
aliases) are resolved locally, without reference to the original
source file directory structure.

      A dynamic and automated file recovery function which
differentiates state information relevance based upon target node and
current directory information for links and aliases is thus defined.
