Oracle Internet Directory Oracle Internet Directory (OID) is used as a central user repository where all the information related to Oracle Identity Management is stored. It helps to simplify the administration of users and provides an application directory based on certain standards for a complex and heterogeneous enterprise. Oracle Internet Directory makes use of the Lightweight Directory Access Protocol that is a well-known standard for directory services. OID is helpful in leveraging the security features, scalability and high availability in Oracle. Users can leverage their identity information from anywhere and anytime by use of Oracle Directory Synchronization feature that helps in integration of Oracle Identity Management with other enterprise user repositories and directories. OID helps in integration of existing digital wallets, entrance privileges and public key certificates. It is also used to provide safe and reliable intranet integration with the help of multi-platform listing structure. Oracle Internet Directory also consists of various administrative tools such as Routing policies, Technical support and System management objects. Oracle Internet Directory can be easily synchronized with distributed applications and Oracle Internet Directory based listings. You do not need to design or create new database structures for Oracle Internet Directory as it uses database structures of Oracle. Moreover, close integration with Oracle database allows you to use many features and technologies that are available for Oracle database only. You may start or stop the Oracle Internet Directory server by use of command line tool provided by Oracle Internet Directory Control Utility. Oracle Internet Directory Monitor is used to intercept and execute the command line statements of Oracle Internet Directory Control Utility. Oracle Internet Directory comprises of Oracle Directory Server, Oracle Directory Replication Server, Oracle Directory Manager, data management tools and command line administration. OID helps to establish consistency in information and centralized user administration across various applications. It stores the information about different users and is a source of information for many applications. This way it helps in centralization of information, which makes the modification process easy when we need to change information about a specific user. There is no need to change information at several places and applications. The data and files are stored in the Oracle Internet Directory in a hierarchical form so that it is easy to locate or search for the file. All this is easily handled by the calendar server of Oracle Internet Directory. You may create or view the groups of calendar users that are present in LDAP directory server. However, you cannot modify the groups of calendar client. In case of failure, you may direct your system to use alternate directory server whenever the main host is not available. You will have to restart the server if you want to access the main host directory again as it will not redirect automatically when connection with main host is reestablished. New versions of Oracle Internet Directory have many new features such as proxy capabilities, highest level of security by independent third party, caching of server-side entries, compatible to more heterogeneous environments etc. to satisfy the requirements of more users.
