New Features and Enhancements

The following sections describe the new features and enhancements offered in the current BEA Tuxedo release:

Oracle RAC Support

Tuxedo 9.1 provides Transaction Monitor support for Oracle RAC by allowing an administrator to specify lists of groups associated with different RAC instances, thereby allowing Tuxedo to ensure that groups associated with different instances of the same RAC database do not participate in the same transaction. The Tuxedo Oracle RAC support feature also provides a way for Tuxedo transaction manager server (TMS) processes to be notified of RAC failover events. Consequently, this allows the TMS to re-obtain a list of prepared transactions from Oracle as required for RAC failover recovery.

Oracle RAC Configuration Documentation

For more information about configuring Oracle RAC with Tuxedo, see the following documentation:

Tuxedo .NET Workstation Client

The Tuxedo .NET Workstation Client enables you to write Tuxedo client applications using .NET programming languages to access Tuxedo services. It also provides connectivity between .NET workstation applications and Tuxedo services.

In Tuxedo 9.0, an early version was released. In Tuxedo 9.1, the Tuxedo .NET Workstation Client has been fully tested and enhanced. Taking advantage of object oriented (OO) technologies and .NET facilities makes new APIs more OO-compliant, as well as easier to use.

The current release supports only the workstation client programming. Native client and server-side programming are not yet supported.

The feature is developed and available as a component of the Tuxedo 9.1 installation process.

Improved overall functionality and performance for CORBA and Java interoperability.

Customer Enhancements

TPESYSTEM Enhancement

Adds detailed information to ULOG when TPESYSTEM occurs for some critical call paths (for example, tpcall, tpacall and tpgetrply).

TPEXIT Enhancement

Indicates "EXITING" status after tpreturn(TPEXIT) is called. Prevents further requests from being dispatched to the server.
