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:
EMS Now Supports IPv6  The EMS server and clients now support IPv4, IPv6 and mixed IPv4/IPv6 environments. For more information, see listen on page 192.
Specify a TX Timeout on XA Resources  You can now specify a default TX timeout for all XA resources. For details, see xa_default_timeout on page 197.
Restrict Selector Evaluation  You can now limit the number of operators that the server reviews during selector evaluation. For more information, see selector_logical_operator_limit on page 194.
Configurable Message Body Tracing Limits  You can now configure the size limits placed on tracing messages. For more informatoin, see the tibemsd.conf parameters max_msg_print_size and max_msg_field_print_size.
Changes in Functionality
The behavior of the following features has changed:
Default SSL Handshake Timeout Changed  The default handshake_timeout setting in the tibemsd.conf has been adjusted. Previously, the timeout was 60 seconds. The default is now 3 seconds. For more information on this parameter, see the TIBCO Enterprise Message Service User’s Guide.
TIBEMS_NO_ACKNOWLEDGMENT Mode  In previous releases, the "Last Acked" and "Total Acked" counts for comumers created from a session with TIBEMS_NO_ACKNOWLEDGMENT mode were zero. Begining in 6.3.0, for a client with TIBEMS_NO_ACKNOWLEDGMENT specified, the "Total Acked" value is nowe equal to the "Total Sent" and the "Last Acked" is generally 1, which is the smallest unit representing the last time a message was acknowledged. This reflects the actual behavior of the TIBEMS_NO_ACKNOWLEDGMENT mode, in which the server acknowledges messages prior to sending them to the consumer, but the clients do not acknowledge receipt.
