Preface : Changes from the Previous Release of this Guide

Changes from the Previous Release of this Guide
This section itemizes the major changes from the previous release of this guide.
Feature Enhancements
The following enhancements are documented in the sections shown:
Improved EMS Server Performance on Multi-Core Machines   This release introduces two new parameters that allow you to fine-tune performance on multi-core machines:
For more information, see Performance Tuning.
Address Consumers with Unacknowledged Messages  The disconnect_non_acking_consumers parameter enables the server to identify consumers with pending messages that exceed the maxbytes or maxmsgs limits. If the limits are reached and the consumer has not acknowledged its messages, the server discards the messages sent to the consumer and disconnects the consumer’s connection. This protects the server against applications that consume messages without ever acknowledging them. See disconnect_non_acking_consumers on page 190 for more information.
Changes in Functionality
The behavior of the following features has changed:
JSON Configuration Files  This release of TIBCO Enterprise Message Service introduces a new configuration option for EMS servers. The EMS server configuration can be stored in a single JSON-based configuration file, tibemsd.json. This file holds the entire configuration of the server without the need of sub-files. Furthermore, a single JSON configuration file holds the configuration settings for a pair of fault tolerant servers. This configuration option is used to enable the Central Administration feature.
For information on starting an EMS server using JSON configuration files, see Starting the EMS Server Using JSON Configuration. For details about Central Administration, see the TIBCO Enterprise Message Service Central Administration guide.
