(n.) A system-level software driver that is used by an EJB container or an application client to connect to an enterprise information system (EIS). A resource adapter typically is specific to an EIS. It is available as a library and is used within the address space of the server or client using it. A resource adapter plugs in to a container. The application components deployed on the container then use the client API (exposed by the adapter) or tool-generated high-level abstractions to access the underlying EIS. The resource adapter and EJB container collaborate to provide the underlying mechanisms-transactions, security, and connection pooling-for connectivity to the EIS. See also connector.

Resource descriptions are stored in SOIF format.
(n.) A mechanism to discover and retrieve metadata about network-accessible resources, known as resource descriptions.
(n.) An instance of a resource type running on a node. An abstract concept representing a resource that was started on the node.
(n.) Provides access to a set of shared resources. A resource manager participates in transactions that are externally controlled and coordinated by a transaction manager. A resource manager typically is in a different address space or on a different machine from the clients that access it. Note: An enterprise information system (EIS) is referred to as a resource manager when it is mentioned in the context of resource and transaction management.
(n.) An object that represents a session with a resource manager.
(n.) An object used for creating a resource manager connection.
(n.) In a Discovery Service, a resource offering defines associations between a piece of identity data and the service instance that provides access to it.

(n.) How often a connector checks a Identity Synchronization for Windows directory source for changes. This periodic check is efficient and only requires reading entries of users that have changed since the last check. The console expresses this value in milliseconds and provides 1000 (1 second) as a default.
(n.) Stores changes in the order of arrival on the local server and not in the order in which these changes were applied to the system. The retro changelog was not designed to function in a multimaster replication environment. Not the same as change log, as the retro changelog is not used in replication. Provides backward compatibility with Directory Server 4.
(n.) A component created so that it can be used in more than one capacity, for example, by more than one resource or application.
(n.) A proxy that performs bidirectional URL rewriting and translation between clients and servers. Unlike a proxy, which exists at the client side, a reverse proxy exists at the server side of the network. In Java Enterprise System Portal Server, the reverse proxy exists in Java Enterprise System Portal Server Secure Remote Access Pack.
(n.) A tool that the MTA uses to route messages to the correct host for delivery. Rewrite rules perform the following functions: (1) extract the host and domain specification from an address of an incoming message, (2) match the host and domain specification with a rewrite rule pattern, (3) rewrite the host and domain specification based on the domain template, and (4) decide which channel queue the message should be placed in. Also known as a domain rewrite rule.
(request for comments) (n.) A document series maintained by the Internet Engineering Task Force that describes the Internet suite of protocols and related experiments. Very few RFCs describe Internet standards, but all Internet standards are published as RFCs. See http://www.imc.org/rfcs.html.
(remote method invocation) (n.) A technology that allows an object running in one Java virtual machine to invoke methods on an object running in a different Java virtual machine.
(n.) A version of RMI implemented to use the CORBA IIOP protocol. RMI over IIOP provides interoperability with CORBA objects implemented in any language if all the remote interfaces are originally defined as RMI interfaces.
(n.) remote method invocation compiler.
(n.) A program that finds all the resources located in a specific portion of a network.
(1) (n.) An abstract logical grouping of users that is defined by the application assembler. When an application is deployed, the roles are mapped to security identities, such as users (principals) or groups, in the operational environment. See also user, group.
(2) (n.) In the J2EE server authentication service, an abstract name for permission to access a particular set of resources.
(3) (n.) In Java Enterprise System Directory Server Access Management Edition, a grouping that represents a selection of privileged operations. By applying the role to a user or a service, the principal can perform the operations. For example, by confining certain privileges to an Employee role or a Manager role and applying the role to a user, the user’s accessibility is confined to the privileges granted to it by the role. Roles are defined using access control instructions (ACIs).
(4) (n.) The function performed by a party in the development and deployment phases of an application developed using J2EE technology. The roles are application component provider, application assembler, deployer, J2EE product provider, EJB container provider, EJB server provider, Web container provider, Web server provider, tool provider, and system administrator.
(n.) Attributes that appear on an entry because the entry possesses a particular role within an associated CoS template.
(n.) The process of associating the groups or principals (or both), recognized by the container with security roles specified in the deployment descriptor. Security roles must be mapped by the deployer before a component is installed in the server.
(1) (n.) (UNIX only) The most privileged user on UNIX machines. The root user has complete access privileges to all files on the machine.
(2) (n.) The outermost element in an XML document. The element that contains all other elements.
(n.) An entry that is automatically generated by the Directory Server and is returned from a baseObject search with a DN that is empty (zero bytes long). The Root DSE provides information to clients about the server\qs configuration, such as a pointer to the subschema entry, a list of the DNs of the naming contexts held by the server, and a list of the LDAPv3 controls and extensions that the server supports. See also DSE.
(n.) The top-level entry of the DIT hierarchy.
(n.) The parent of one or more sub suffix. A directory tree can contain more than one root suffix.
(n.) A system responsible for determining on which path network traffic will flow. A router uses a routing protocol to gain information about the network and algorithms to choose the best route based on several criteria known as a “routing matrix.” In Open Systems Interconnect terminology, a router is a Network Layer intermediate system. See also gateway.
See message routing.
(n.) The internal databases that hold the information about message originators and recipients.
(n.) A single data record that contains values for each column in a table.
(n.) An object that encapsulates a set of rows retrieved from a database or other source of tabular data. The RowSet object extends the java.sql.ResultSet interface, enabling the ResultSet object to act as a component based on the JavaBeansTM component architecture.
(remote procedure call) (n.) A mechanism for accessing a remote object or service.
(round trip time) (n.) The elapsed time for transit of a signal over a closed circuit (from the server to the client and back). This delay is important in systems that require two-way interactive communication where the RTT directly affects the throughput rate. In the context of Java Enterprise System Directory Server, the RTT and the TCP window can have a significant impact on replication performance over a wide-area network. Also known as round-trip delay time.
(n.) Logical tests applied to determine whether a condition is met. The robot uses rules as part of filters for determining types of content to index and in classification rules to determine what category to assign to a resource.
