JMS Messaging Features

This topic provides a brief overview of messaging features offered by the JMS IQ Manager working together with the JMS clients.

Message Delivery Order

The JMS IQ Manager provides the following special facilities to maintain message order in concurrent processing and across message destinations. These facilities are in addition to those mandated by the Java Message Server specification.

Configuring the JMS IQ Manager for special first-in, first-out (FIFO) ordering modes for queues
Specifying a set of message destinations (a time order group) for which fully serialized processing occurs
Configuring topics and queues for concurrent or serial processing

The following sections describe each method of processing order. For detailed information about processing order, refer to Message Processing Order.

Message Producer Priorities

Oracle Java CAPS Enterprise Service Bus enables you to set message priorities for topic publishers and queue senders. The priority level causes all messages produced by the client to have that same priority level. For more information, refer to Message Producer Priorities.

Distributed Transactions

The JMS IQ Manager enables you to configure JMS Client properties for distributed transactions using the XA protocol. For more information, refer to Transaction Mode.

Security

The Oracle Java CAPS Enterprise Service Bus provides role-based security for the JMS IQ Manager by requiring authentication by means of SSL or LDAP. When authentication is enabled, access to the JMS IQ Manager is only granted when the connection has a valid user ID and password.

JMS IQ Manager security is enabled by default. To disable security, refer to Using LDAP with Java CAPS.

Runtime Management

Oracle Java CAPS Enterprise Service Bus provides two alternatives for managing JMS IQ Managers:

Enterprise Manager

Enterprise Manager offers a graphical interface containing comprehensive runtime management functions. You can monitor message destinations, and view message properties and payloads. For more information, see Using Enterprise Manager Management Application in Java CAPS.
MS Control utility

The MS Control utility is a command-line utility that enables you to manage many advanced aspects of the JMS IQ Managers. For details, refer to JMS Provider Management.

Note - Other message servers supported by Java CAPS have their own runtime management tools.
