chat types

Oracle Real-Time Collaboration provides two basic types of chat:

Client Connection Manager

An Oracle Real-Time Collaboration core component that connects Oracle Messenger Windows or Java clients to the Oracle Presence Server. Its component name is rtc-connmgr.


A group of Oracle Real-Time Collaboration instances that have the same InstanceLocation property and that use the same Oracle Real-Time Collaboration Repository.


A collection of Oracle Messenger users that appear under the Community tab in the RTC Messenger window. See group.


A set of processes within an instance that perform an identical function, such as a multiplexer for handling communications between components. Each component has a component type and component name. See the Oracle Real-Time Collaboration Administrator's Guide for descriptions of components and how to administer them with the rtcctl utility.

conference ID

The unique ID that the Oracle Real-Time Collaboration system assigns to a chat conference or Web conference.

conference key

An additional text string that a Web conference host can assign to a conference. Attendees must enter the key before they can enter the conference.

conference mode

A method for sharing or displaying Web conference content. Each mode has a different appearance and has a set of features associated with it. Oracle Web Conferencing offers the following modes:


See Oracle Messenger console, Oracle Web Conferencing console, and Oracle Web Conferencing playback console.


A business colleague with whom you exchange chat messages or participate in Web conferences. Your contacts are displayed in the Oracle Messenger window.

core components

The main components of Oracle Real-Time Collaboration: Client Connection Manager, OC4J_imeeting, Oracle Real-Time Collaboration Presence Server, Multiplexer, Redirector, Oracle Web Conferencing Server, Process Manager, and Voice Proxy Server. All of these components are installed when Oracle Real-Time Collaboration is installed.

Data Services

See Oracle Real-Time Collaboration Data Services.

desktop sharing mode

One of the modes used during a Web conference. This mode lets a host share an application, an area of the desktop, the entire desktop, or a Web browser.


The "demilitarized zone" is a subnetwork located between a company's corporate intranet and the Internet.

Document Conversion Server

The server that converts supported document types to HTML for viewing in document presentation mode. Its component name is rtc-docconv.

document presentation mode

One of the modes used during a Web conference. This mode is optimized for presenting Microsoft Office documents and *.txt, *.jpg, and *.gif files. The host and presenters can use a slide-show type of navigation, index, and thumbnails. Documents must first be placed in the user's personal materials repository before they can be shared in this mode.

effective value

The value for an Oracle Real-Time Collaboration property as used by the system at runtime, based on the property as set by the administrator and by users through various Preferences dialogs, and based on the inheritance order (system, site, instance, component) and whether the property value has been forced with the -force option. See actual value.

end page

end user

A registered user who can perform all typical tasks with Oracle Real-Time Collaboration, including scheduling conferences, downloading the Oracle Messenger, Oracle Web Conferencing, and Oracle Real-Time Collaboration Add-In for Microsoft Office consoles, uploading materials for conferences, joining conferences, and viewing conference and instant message archives. See business administrator and business monitor.

enrollable conference

A conference that requires users to complete an enrollment form, listing their name, company, address, phone, and e-mail address before they can participate in the conference. Such conferences are typically created for web seminars, sales meetings, or other conferences that include nonregistered users whose personal information the host wishes to track.


An option of the setProperty command that requires that a property setting is inherited by all subsequent property scopes. For example, you can force the value of a property set on the system so that all sites and instances under that system use that value as well. See properties and rtcctl.


In the Oracle Messenger window, groups consist of contacts that have been organized by the user under the Contacts tab, or groups of individuals listed as a community under the Community tab. Administrators can also create special groups through the rtcctl utility for use with group presence services to respond to requests made through Oracle Real-Time Collaboration integration services.

group chat

See chat types.

group presence

Group presence is used to identify the availability of a group of users created by an administrator to respond to requests made through Oracle Real-Time Collaboration integration services.

group presence services

Oracle Real-Time Collaboration integration services that allow multiple users to interact with a group of specialized contacts, and members of that group to interact with each other. For example, a group might be created to provide a single logical entry point for customer service questions, distributing a queued chat message to any member who picks up the communication. Such groups must be created by the administrator using the rtcctl utility.

guest chat user

A user outside of the Oracle Internet Directory enabled to make chat requests to Oracle Messenger through an Oracle Real-Time Collaboration integrated service.


A person who initiates a Web or chat conference. The host can grant control of a Web conference to a presenter.
