Title
Support for Transactions and Replication in the EAN Directory Service
Abstract
The OSI directory system manages a distributed directory information database of named objects, defining a hierarchical relationship between the objects. An object consists of a set of attributes as determined by the object's class. Attributes' are tuples that include a type and one or more values. After presenting an overview of the X.500 standard, we discuss the use of atomic transactions within the EAN X.500 implementation. Atomic transactions are used within the database component of the Directory Service Agent (DSA). Non-standard extensions to X.500 were made to provide user agents with a means of forming atomic transactions. The new interface allows any sequence of standardized X.500 operations to be executed in the context of an atomic transaction. Support is also provided for the two phase commit protocol, allowing two or more directories to atomically commit updates. This work was done in conjunction with a distributed multidatabase (MDBS) project which used the X.500 directory to store its schema information [5]. Finally, ongoing work to provide replicated master DSAs is described.
