send out-of-band notifications to clients that aren't necessarily waiting for a response. Brokered events allow application to subscribe to events of interest and when another application posts an event, all applications subscribed to that event receive it. This allows applications to use an event driven model instead of the more typical request/response model. As well this provides a publish and subscribe messaging model that can be combined with /Q. Add-on Products Oracle offers a number of add-on products to Tuxedo. Mainframe re-hosting In March 2010, Oracle announced two new products. Application Runtime for CICS and Batch along with the associated Oracle Tuxedo Application Rehosting Workbench allows the migration of IBM Customer Information Control System (CICS) and batch applications onto Tuxedo on distributed systems. By providing automated conversion tools, CICS equivalent API pre-processor macro expansion, and a JES-2 like Batch execution environment, the migration of mainframe applications is greatly simplified. SALT This product provides a bi-directional web services SOAP/HTTP(S) gateway. This gateway allows Tuxedo services to be accessed by external SOAP clients without making any changes to the Tuxedo service. Likewise, Tuxedo applications can call an external web service as though it were a local Tuxedo service. The latest version of SALT supports WS-AtomicTransactions and modules for Apache Web Server, Oracle HTTP Server, and Oracle iPlanet Web Server, that allows the creation of dynamic web content by calling Tuxedo services. In version 12.1.3 SALT added support for RESTful services. TSAM Plus This product provides centralized monitoring capabilities for multiple Tuxedo domains. TSAM Plus agents are deployed on the machines in a Tuxedo domain. These agents collect metric data from the running Tuxedo processes based on a configured policy, and send the data back to the TSAM Plus Manager where it is used historically or in real time. TSAM Plus provides configuration information, call path, call pattern, service execution, transaction, and more monitoring metrics. TSAM Plus also monitors Tuxedo ART CICS and Batch applications. An additional component of TSAM Plus is a plug-in for Oracle Enterprise Manager Cloud Control that provides full operation, configuration, administration, and management of a Tuxedo application. Tuxedo Mainframe Adapters (TMA) This product provides a set of gateway processes that run on Tuxedo that communicate with a mainframe using its native protocols. This gateway provides bidirectional integration between mainframe and Tuxedo platforms and makes Tuxedo appear as a remote CICS or IMS region to the mainframe, and the
