Abstract: PROBLEM TO BE SOLVED: To provide a bidirectional meta-directory agent for managing entries from different kinds of data sources. SOLUTION: The meta-directory agent includes a data source converter layer; a filer and rule layer for blocking an unallowable change; a mapping layer for converting a local set of an attribute name to a set of a meta-directory attribute name, inversely converting an attribute in a change command and converting the change command between an intra-agent common format and a directory change protocol; an extensible user customize layer for implementing a custom meta-directory agent function; and a meta-directory interface for transmitting and receiving the change command by means of the directory change protocol.

Abstract: An improved file system apparatus and method for minimizing the length of time a client system waits before declaring a data communication link disconnected. The apparatus and method dynamically modify a file system request time-out value based on the actual length of time required to service each file system request. In one embodiment, a time-out value is determined for each request type based on the actual response time and a buffer time for each request type. The response timer is based on readings from a system clock therefore operating as a low overhead process. A monitoring system periodically tests the server to ensure that a physical connection still exists.
