Oracle Tuxedo 12c LaunchGepubliceerd: Auteur: Michel Schildmeijer Categorie: Oracle
At July the 31st, Oracle has launched the next member of the 12c family, Oracle Tuxedo 12c. This will be the 4th in row, so for now the following products are on 12c release:
- Oracle Enterprise Manager 12c.
- Oracle WebLogic Server 12c.
- Oracle OpsCenter 12c
- And now, Oracle Tuxedo 12c.
My first experience with Tuxedo was in 2000, when I worked for a big international trading Bank. Tuxedo was at that time still BEA Tuxedo at level 6.5. It was used as a transaction messaging system for the Foreign Exchange Money Market , which participated of a worldwide Foreign Exchange Settlement solution called CLS.
Oracle acquired BEA , as you all know in 2008, and a long time it puzzled me what was going to happen with my “old love” Tuxedo.
Now, that’s for the history lessons but:
What is in fact Oracle Tuxedo?
Tuxedo is a transaction processing system or transaction-oriented middleware, or enterprise application server for a variety of systems and programming languages.
Tuxedo was designed for high availability and to provide scalable applications to support a lot transactions per second on commonly available distributed systems. It was developed and designed by AT&T. They required online transaction processing (OLTP) capabilities.
Tuxedo is a message routing and queuing system. Requests are sent to named services and Tuxedo uses memory based inter-process communication facilities to queue the requests to servers. The requester is unaware of where the server that actually processes the request is located or how it is implemented. In fact, Tuxedo was already implementing the SOA, in the early days before even the concept of SOA was familiair to any one.
Now Oracle has optimized and rebranded Tuxedo for it’s engineered system Exalogic. Oracle poses Tuxedo as the new “C, C++, COBOLApplication Server for Conventional and Cloud Environments”. From here Oracle tries to reach the Mainframe segment with their “rehosting Mainframe and COBOL applications” strategy. You could migrate those applications to an Exalogic infrastructure with in this case the Tuxedo as a middleware solution for these applications, where on the other side of the Exabus stack Coherence for JAVA applications. Tuxedo has support for various languages like C, C++, Python, JAVA, PHP, COBOL and Ruby which makes it highly flexible.
Let’s take a look to the various components Oracle Tuxedo 12c has to offer.
Oracle Tuxedo 12c Components (screenshot from tux12claunchtechwebcast_v11.pdf):
Tuxedo System and Application Monitor (TSAM)
TSAM is the solution for integrated systems monitoring. In this 12c version it is Enterprise Manager 12c ready and can be fully integrated. You can monitor the full stack of Tuxedo components, do rule based auto data purge and monitor same set of Tuxedo domains from more than one console.
Typical TSAM overview in Enterprise Manager 12c:
Tuxedo Message Q
One of famous features of Tuxedo is of course it’s messaging system. It allows messages to be queued to persistent or non-persistent storage (memory) for later processing or retrieval. ATMI, the Application-to-Transaction Monitor Interface (ATMI) provides an interface that allow messages to be added to or read from queues. All the best of of Tuxedo /Q and Oracle MessageQ have been put together, and provides dual-api, Tuxedo /Q API (for compatibility) TMQ API (access to all features). Some of the combined features are:
- Offline message queues.
- Message journals.
- Delivery notification.
- Store and forward between queues across domains.
- XA transaction support.
- Asynchronous messaging
- Dynamic queues.
- Naming services.
Tuxedo has some adapters:
- JCA Adapter: This adapter is a wrapper to the WebLogic Tuxedo Connector (WTC) as part of WebLogic/JAVA Integration. WTC can only be used on WebLogic, but the JCA adapter allows deploying these capabilities between between Oracle Tuxedo applications and JAVA applications. It can call several Tuxedo services out of JAVA Apps like servlets, JSPs, EJBs and POJOs, and also the other way around. In this way you can integrate Tuxedo services into your other existing SOA layer.
- Mainframe Adapters: This includes SNA and TCP adapters which consists of a redundant configuration for bi-directional connectivity. Whit this solution you can connect 1 CRM connects to multiple CICS/IMS regions.
- IBM MQ Adapter: This adapter is multi-threaded and event driven which reduces CPU utilization and has a better throughput. It can access MQ message headers, which uses FML32 functions to manipulate fielded buffers related to errors. With this feature applications run faster if data is transferred to structures for manipulation.
With SALT you have the possibility to expose a certain Tuxedo service as a WebService. It is a web-based configuration tool and uses a metadata repository.
The magic keyword here is: Tuxedo ART (Application Runtime) for CICS, IMS. The ART Workbench helps to speed up and ease rehosting projects, by automating the code and data migration.
- CICS Programming model and Services.
- IMS TM Programming model and Services.
- Batch Execution Environment.
- Application Repository & Cataloguer.
- Language migration tools: COBOL, JCL, SQL.
- Data migration tools: VSAM and Flat Files, DB2.
- Natural/Adabas migration.
- IDEAL/Datacom migration.
- ADSO/IDMS migration.
Migrating Mainframe with ART Solution:
Development tools for programming Tuxedo 12c
The IDE that’s been utilized for Tuxedo is the Solaris Studio IDE. It’s an integrated development environment for Tuxedo applications with all the common features an IDE should have like creating, building, running and debugging.
Solaris Studio for Tuxedo 12c:
Optimizations for Exalogic
Oracle Tuxedo 12c is one of the components that will also run on Exalogic, especially for the mainframe rehosting story. Tuxedo has a plugin for Virtual Assembly builder and makes use of all the exclusive features of Exalogic, like Infiniband and SDP, shared memory usage and zero buffer copies for more efficient data transfer.
For installation you need to install one Tuxedo + applications across all your Exalogic nodes. The Tuxedo processes use a pointer to the shared memory segments where the actual message queue exists.
Personally, my “love” for Tuxedo hasn’t disseapeared and it pleases me to see how Oracle has extended it with many new features.
From an objective point of view: Tuxedo has been a proven concept over the years and is being used as reliable and robust by many enterprises in the financial and telco-industries. However I do think Oracle has to put great effort in getting traditional mainframe candidates into Tuxedo. But they won’t regret it if they do!
