Application Service Version- Oracle Tuxedo 12c

The application service version feature provides a configuration-driven approach to deploy different versions of Tuxedo application services in a domain or across domains without changing the existing application. With application service version feature, you can logically partition Tuxedo applications into different virtual application domains, machines, and server groups to respond to various business requirements, including uninterrupted application upgrade for high availability.

The Application Service Versioning feature provides MIB support to obtain and change version information at runtime. It also provides cross domain, TMQFORWARD and COBOL support.

You can use the application service version feature to:

  • Plan, develop, test, scale and deploy Oracle Tuxedo applications
  • Partition different virtual application domains and different virtual server groups in the current Oracle Tuxedo management hierarchy.
  • Set up user applications according to a defined version
  • Seamlessly upgrade the application and reduce upgrade procedure risk

Check out the video below to learn more about what to consider when using application service version, new configuration attributes in the UBB configuration file and the domain configuration file, and to see a demo.

Calling an existing Web service from Tuxedo is easy—See for yourself

Find out how easy it can be to invoke an existing web service from Tuxedo. Check out the YouTube video with Maurice Gamanho, Oracle SALT: Calling Web Service, which includes a live demo starting with an actual web service interface and ending with an application calling it.

Oracle SALT, the Web services gateway for Tuxedo, provides transparent, reliable access to existing Oracle Tuxedo services as standard Web services and enables Tuxedo applications to call standard Web services in a high-performance, easy-to-use, and configuration-driven model.

In this video, you will see a step by step demo that shows how Oracle Tuxedo applications can call external Web services as Tuxedo services, with the gateway seamlessly transforming the call using SOAP over HTTP protocol. Some of the many benefits include:

·         Widespread access to applications using Web services without any Web services specific coding

·         Interoperability among distributed applications that span diverse hardware and software platforms

·         Improved performance, scalability, reliability, and standard support

In addition to the benefits mentioned above, the Oracle SALT gateway is also helpful when it comes to configuring extra features such as security, encryption, transactions, reliable messaging, and proxy settings. Oracle SALT uses the Oracle Tuxedo security framework for authentication, protects point-to-point transactions using Secure Socket Layer (SSL) protocols, and can route traffic through SOCKS proxies.

Integrating Oracle Tuxedo Applications into a SOA Environment

Oracle Tuxedo Oracle Tuxedo is the C/C++/COBOL application server of choice, running mission-critical applications in conventional and cloud deployments. It is deeply integrated with WebLogic Server enabling bi-directional transactional communication between Java applications and C/C++/COBOL applications.

Easy Integration into SOA environments
As one of the original SOA platforms, everything in Oracle Tuxedo is a service. Oracle Tuxedo services are location and implementation independent. They adhere to a contract, and are interoperable with other Oracle Tuxedo services and service oriented platforms. This makes integrating Oracle Tuxedo applications into a SOA environment natural and straightforward, regardless if the business logic is written in C, C++, Java, COBOL, Python, Ruby, or PHP.

Client Only and Server to Server Options

There are a number of integration techniques that can be used to integrate Oracle Tuxedo applications into a SOA world. The first decision to make when choosing an integration options is whether a Client Only option or a Server to Server option best fits your business needs. 

Client Only Options
For environments where requests flow only from the client environment to Oracle Tuxedo, there are Client Only Options. The client’s transaction context is never extended to the Oracle Tuxedo system. Oracle Tuxedo transactions started by the client are delegated to Oracle Tuxedo and are separate from any transaction context in which the client may be participating.

Server to Server Options
For environments where Oracle Tuxedo is able to make calls to the non-Oracle Tuxedo system as well as receive calls, there are Server to Server integration options. Some of these options support distributed transactions and security context propagation. 

Java Integration

Oracle Tuxedo provides the following Java integration options.  

  • Oracle WebLogic Tuxedo Connector (WTC), a standard component of Oracle WebLogic Server, provides bi-directional service invocations to and from Oracle Tuxedo and Oracle WebLogic Server within context of global, XA transactions. Using WTC,  based on Tuxedo domains, Tuxedo applications can invoke JEE applications running on WebLogic and vice-versa.  With its integrated JMS bridge, JMS Messages can flow to/from Oracle Tuxedo /Q queues and vice-versa. 
  • Oracle Tuxedo JCA Adapter provides similar capabilities as WTC, but for all JEE application servers. It allows bi-directional, transactional interactions between JEE applications and Oracle Tuxedo applications.
  • Native Java Support available in the Oracle Tuxedo 12c release means services can be implemented in Java as plain old Java objects or POJOs. Developers can use JATMI to develop Oracle Tuxedo services in Java and leverage Oracle’s scalable, highly available infrastructure to create or extend their enterprise to class SOA applications.
  • Jolt provides access to Oracle Tuxedo services from essentially any Java environment
    ranging from stand alone Java applications, applets running inside a browser, to clients running inside a JEE application server. It provides a simple set of Java classes that support  Oracle Tuxedo client facilities such as invoking services, enqueuing and dequeuing messages to Oracle Tuxedo /Q queues, and subscribing to Oracle Tuxedo Event Broker for publish and subscribe interactions.

Web Services Integration

The Oracle Services Architecture Leveraging Tuxedo (SALT) provides bi-directional SOAP/HTTP support for Oracle Tuxedo applications. This product is completely configuration driven, meaning that no coding is necessary to access remote web services or to allow remote applications to access Oracle Tuxedo services as web services.

SALT provides a high performance point to point integration mechanism using open standards. It is an ideal solution for customers standardizing on SOAP/HTTP as their protocol of choice for integrating applications.  SALT supports most of the common web services standards including SOAP 1.1 and 1.2, SOAP with attachments, MTOM, WSDL 1.1, WS-Policy, WS-Addressing, WS-ReliableMessaging, WS-Security 1.0 and 1.1, WS-Coordination, and WS-AtomicTransaction 1.0. This allows integration with most other web services platforms including Oracle WebLogic Server, Axis for Java 2.0, Microsoft .NET framework 3.0, Oracle Service Bus, and Oracle BPEL, as well as most other popular SOAP/HTTP offerings.

.NET Integration

Oracle Tuxedo includes support of a .NET client library that can be used to access Oracle Tuxedo services from a .NET application. Like Jolt, the .NET client is a client only offering so .NET application can invoke Oracle Tuxedo services, but Oracle Tuxedo cannot invoke .NET applications.

WebSphere MQ Integration

Oracle Tuxedo ships with a bi-directional MQ adaptor that allows messages placed on MQ queues to be delivered to an Oracle Tuxedo service and the reply from the Oracle Tuxedo service to be placed on the output MQ Queue. Applications needing staged transactional delivery of requests can use standard Oracle Tuxedo distributed transaction management to ensure exactly once processing of messages.

Mainframe Services Integration

The Oracle Tuxedo Mainframe Adapter (TMA) provides an excellent foundation for integrating legacy mainframe systems, such as IBM CICS and IMS/TM,  into a modern SOA environment. With TMA, mainframe applications see Tuxedo services as though they were local and Tuxedo services see mainframe applications services as local services.  allow the sharing of services between Oracle Tuxedo and the mainframe systems.

Like other integration options built on Oracle Tuxedo’s domains technology, TMA supports identity propagation and support distributed transactions.

Service Bus Integration
Oracle Service Bus (OSB) is an enterprise service bus that supports the integration, mediation, and monitoring of a variety of types of services.   For each type of service supported by OSB a transport is used to handle the connection and interfacing to the specifics of the service. OSB also has a built-in transport for Oracle Tuxedo.  The Oracle Tuxedo transport supports Oracle Tuxedo based business services that can be accessed from any OSB proxy as well as Oracle Tuxedo proxy services which allow Oracle Tuxedo applications to call services mediated by OSB.

Oracle Tuxedo provides many ways to connect with other SOA platforms and environments. For more detailed information about each of the integration choices, download the white paper, Oracle Tuxedo in a SOA World.

Leveraging Infiniband to bypass the BRIDGE

As Deepak mentioned in the previous post, the Tuxedo team has spent a lot of effort in leveraging some of the unique features of the Exalogic platform.  Specifically we've developed support for Remote Direct Memory Access.  This is a feature of Infiniband that allows one node to read or write directly into the memory of another node.  In particular this can all be done from user mode, meaning there is no need to enter the operating system kernel to pass information from one node to another node.

Tuxedo 11gR1PS2 uses this RDMA capability to bypass the BRIDGE process used in a Tuxedo cluster (MP mode domain.)  In standard hardware environments, when a request is made to a server on a remote node, the request is given to the BRIDGE which in turn passes the request to the remote BRIDGE which eventually places the request on the appropriate server's queue.  The reply message takes the reverse path being placed on the local BRIDGE queue, relayed to the remote BRIDGE by a network connection, and then finally placed on the client's reply queue.  In some cases this becomes a bottleneck as the BRIDGE is only partially multi-threaded.  So on high core count systems with a lot of requests being made to remote servers, the BRIDGE creates a throughput bottleneck.  As well the BRIDGE introduces substantial latency as the total round trip requires 4 System V IPC messages and two network messages.  Where a local request/response can be performed in about 35 microseconds, a remote request/response through the BRIDGE can take about 1100 microseconds.  This diagram shows the message flow:


With the BRIDGE bypass feature, a native client uses RDMA to place its request directly on the remote server's queue, and the reply is placed directly on the client's reply queue.  This eliminates two message queue operations and two network operations.  The net result is that throughput increases 7 fold for remote operations by bypassing the BRIDGE and reduces latency from 1100 microseconds to 160 microseconds.  This diagram shows the message flow:



For the next release of Tuxedo sometime this summer, we're planning even more optimizations to achieve even more throughput and lower latency for remote operations.

Tuxedo is now optimized for Exalogic

We are in 2012! Wish you all a very happy new year. In case you missed the announcement, we released a new version of Tuxedo, Tuxedo 11.1.1.3.0, middle of December 2011. If you have seen the press release, you know this release includes Tuxedo optimizations for the Exalogic platform. This is first of the blog in a series to talk about Oracle Tuxedo 11.1.1.3.0 features.

We have changed the guts of Tuxedo to take full advantage of Exalogic technology, specially related to Infiniband. These technologies are SDP (Socket Direct Protocol) and RDMA over Infiniband. All Tuxedo components now can use SDP instead of TCP/IP when communicating with other components running on Exalogic and/or Exadata. Use of SDP generally results in less CPU consumption, leaving more for applications to use. With RDMA over Infiniband, clients/servers on one node can talk directly to servers on the other node without going through the BRIDGE process. This serves two purposes, it eliminates BRIDGE as the bottleneck and reduces the latency of communication by an order of magnitude, in some case to as low as a few microseconds. The benchmarks results from our in-house tests have been shown dramatic improvement in throughput.

In addition, one cool feature Tuxedo 11.1.1.3.0 release includes is self tuning of SPINCOUNT. Tuxedo now monitors application workload on Exalogic and based on the workload it adjusts the value of SPINCOUNT dynamically for the best use of CPU cycles. Optimized tuning of SPINCOUNT is crucial as SPINCOUNT is used in the context of bulletin board locking and impacts almost each and every operation in Tuxedo. With Tuxedo 11.1.1.3.0 on Exalogic, there is one less thing to worry about when configuring Tuxedo.

Other features includes in this release are:

- OVM 3.0 certification

- OVAB (Oracle Virtual Assembly Builder) plugin for Tuxedo

- TLOG Store in Database

Keep an eye at this blog for more details to follow!
