Table 1 Revision History This document contains release notes for the Oracle Tuxedo 12c Release 2 (12.1.3). It includes the following topics:Oracle Tuxedo 12c Release 2 (12.1.3) includes the following new major features and enhancements:FAN (Fast Application Notifications) are events published by Oracle RAC to indicate configuration changes. A system server, TMFAN, is introduced to monitor FAN events and automatically reconfigure Tuxedo server connection to the appropriate Oracle RAC instance for planned DOWN events, UP events, LBA (Load Balancing Advisor) notifications, etc.This feature enables application in an Oracle Tuxedo domain to directly communicate with another application in another domain using RDMA technology on Exalogic. Applications can directly access IPC queues of remote applications removing GWTDOMAIN as a potential bottleneck, thus reducing the latency and improving throughput and scalability.This feature enables creation of TLOG in Oracle Database. This feature is now available on all platforms supported in Oracle Tuxedo 12c Release 2 (12.1.3).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.Oracle Tuxedo increases the maximum number of outstanding tpacall() to 2048, making it possible to invoke more tpacall() before tpgetrply().For more information, see File Formats, Data Descriptions, MIBs, and System Processes Reference and ATMI C Function Reference in the Oracle Tuxedo Reference Guide, and How to Enable Security Service for OES.
