About This Oracle Tuxedo Release

This topic includes the following sections:

What’s New and Improved

Oracle Tuxedo Release 11g Release 1 (11.1.1.3.0) includes the following new features and enhancements:

Oracle Tuxedo Exalogic Improvements

Self-tuning Locking Mechanism

Allows you to dynamically tune SPINCOUNT while taking the runtime environment into consideration, thus improve performance especially when there are heavy load on the system using XA without administrator configure SPINCOUNT with a static value.

For more information, see Oracle Tuxedo/Oracle Exalogic Users Guide and File Formats, Data Descriptions, MIBs, and System Processes Reference in the Oracle Tuxedo Reference Guide.

Direct Cross Node Communication Leveraging RDMA

In Oracle Tuxedo applications, processes on separate machines communicate with each other through bridge processes using a socket. The communication between bridges can be considerably slow.

This feature utilizes RMDA through which processes on separate Exalogic machines can communicate with each other directly. If Oracle Tuxedo application processes use RDMA instead of bridge processes overall performance is improved.

For more information, see Oracle Tuxedo/Oracle Exalogic Users Guide

Oracle Tuxedo SDP Support

This feature allows Oracle Tuxedo user to configure which protocol to use, either SDP or normal TCP between Oracle Tuxedo components including Domain gateware, bridge, work station client and WSH, Jolt client and JSH t to leverage the advantages Exalogic provides such as high bandwidth, low latency as well as reduced CPU involvement.

For more information, see Oracle Tuxedo/Oracle Exalogic Users Guide, File Formats, Data Descriptions, MIBs, and System Processes Reference, Command Reference, and ATMI C Function Reference in the Oracle Tuxedo Reference Guide. Also, Configuring the Oracle Jolt System in Using Oracle Jolt in the Oracle Tuxedo Users Guide.

TLOG Information To Oracle Database

Allows you the flexibility of using an Oracle database instead of file system to store the TLOG. You can also leverage various high availability Oracle database features in disaster recovery as needed.

For more information, see About Transactions in Setting Up an Oracle Tuxedo Application in the Oracle Tuxedo Users Guide, File Formats, Data Descriptions, MIBs, and System Processes Reference and Command Reference in the Oracle Tuxedo Reference Guide.
