This chapter provides an overview of Oracle Communications Messaging Server, and describes the basic administration tasks and tools used to perform those tasks.
Oracle Communications Messaging Server is an extensible framework of cooperative modules that creates an enterprise-wide, open standards–based, scalable electronic message handling system. This system is the combination of message user and transfer agents, message stores, and access units that together provide electronic messaging.
Messaging Server provides a number of messaging capabilities, including:
Message Store. Provides a modular and scalable repository of user messages.
Message Transfer Agent. Responsible for routing, transfer, and delivery of internet mail messages. Oracle Communications Messaging Server includes a fast, scalable, and flexible MTA that replaces the Sendmail utility bundled with most UNIX systems.
Message Access. Provides client access to messages over standard protocols IMAP and POP3. HTTP-based access is offered for web clients and Lemonade Profile 1 is supported for mobile devices.
When you install Messaging Server, you must decide if you want to use Unified Configuration or legacy configuration. Unified Configuration is an improved, streamlined process to configure and administer Messaging Server. Unlike in legacy configurations, Unified Configuration uses validation to verify configuration accuracy, and employs a single tool to configure the entire Messaging Server configuration (with a few exceptions). For more information, see "Overview of Messaging Server Unified Configuration."
Note:
This guide describes how to administer Messaging Server by using Unified Configuration.A Messaging Server administrator is responsible for the day-to-day tasks of maintaining and managing Messaging Server and its users. The tasks also include managing Messaging Server components and potentially other Unified Communications Suite components.
You perform the following tasks as a Messaging Server administrator:
Stopping and starting Messaging Server
Managing user accounts
Monitoring Messaging Server
Tuning Messaging Server performance
Migrating data to Messaging Server
Backing up and restoring files
Troubleshooting Messaging Server
Messaging Server provides the msconfig command-line utility for administering the server. For more information, see "Messaging Server Command-Line Reference." In addition, Messaging Server provides command-line utilities to manage the message store and the mail transfer agent (MTA). See "Message Transfer Agent Command-line Utilities" and "Message Store Command Reference" for more information.
