ADOBE CONNECT ENTERPRISE SERVER 6

Installation and Configuration Guide

Connect Enterprise Server is a built on J2EE using components of Macromedia

JRun

™

from Adobe. Also called the

application server, it manages users, groups, on-demand content, and client sessions. Some of the application server’s

duties include access control, security, quotas, licensing, and auditing and management functions such as clustering,

failover, and replication. It also transcodes media, including converting Microsoft PowerPoint and audio to Flash.

The application server handles meeting requests and content transfer requests (slides, HTTP pages, SWF files, and

files in the File Share pod) over an HTTP or HTTPS connection.

Note: The application server includes a web server and is sometimes referred to as the “web/application server”.

Flash Media Server, also called the meeting server, is installed with Connect Enterprise Server to handle real-time

audio and video streaming, data synchronization, and rich-media content delivery, including Acrobat Connect

Professional interactions. Some Flash Media Server tasks include meeting recording and playback, timing the

synchronization of audio and video, and transcoding—converting and packaging data for real-time screen sharing

and interaction. Flash Media Server also reduces server load and latency by caching frequently accessed web pages,

streams, and shared data. Flash Media Server streams audio, video, and accompanying meeting data over Adobe’s

high-performance Real-Time Messaging Protocol (RTMP or RTMPS).

Connect Enterprise Server requires a database for persistent storage of transactional and application metadata,

including user, group, content, and reporting information. You can use the embedded database engine (MSDE)

included in the Connect Enterprise Server installer, or you can install the full version of Microsoft SQL Server 2000

or 2005. (The embedded database engine is included in the Connect Enterprise Server installation; Microsoft SQL

Server is not.)
