Understanding Oracle SALT

Oracle Service Architecture Leveraging Tuxedo (SALT) is an add-on product option for Oracle Tuxedo, enabling Oracle Tuxedo applications to participate in SOA environments. Oracle SALT has two major components: native Web services stack and SCA container.

Oracle SALT allows external Web services applications to invoke Oracle Tuxedo services as Web services, and Oracle Tuxedo applications to invoke external Web services. Oracle SALT does not require any coding to achieve this. In addition, Oracle SALT includes an SCA container, which allows you to develop new SOA applications focusing on business logic, while still taking advantage of Oracle Tuxedo infrastructure. SCA container also helps with effective reuse of existing application assets.

Understanding Oracle SALT Web Services

Oracle SALT complies with standard Web service specifications (SOAP 1.1, SOAP 1.2, and WSDL 1.1), allowing Oracle SALT to interoperate with other Web service products and Oracle SALT Overview development toolkits. Oracle Tuxedo applications can easily integrate with Web services applications using Oracle SALT.

What Are Web Services?

Web services are a set of functions packaged into a single entity made available to other systems on a network. They can be shared and used as a component of distributed Web-based applications. The network can be a corporate intranet or the Internet. Other systems, such as customer relationship management (CRM) systems, order-processing systems, and other existing back-end applications, can call these functions to request data or perform an operation. Because Web services rely on standard technologies which most systems provide, they are an excellent means for connecting distributed systems together.

The software industry has evolved toward loosely coupled service-oriented applications that interact dynamically over the Web. The applications break down the larger software system into smaller modular components, or shared services. These services can reside on different computers and can be implemented by vastly different technologies. They are packaged and made accessible using standard Web protocols, such as XML and HTTP.

Web services share the following properties that make them easily accessible from heterogeneous environments:

•	Web services are accessed using widely supported Web protocols such as HTTP.

•	Web services describe themselves using an XML-based description language.

Web services communicate with clients (both end-user applications or other Web services) through simple XML messages that can be produced or parsed by virtually any programming environment or manually, if necessary.

Why Use Oracle SALT?

Oracle SALT is a native Oracle Tuxedo Web service integration solution. It reduces Oracle Tuxedo/Web service integration costs and decreases conversion processes that may exist with other solutions for accessing Oracle Tuxedo services. It enables seamless connectivity between Oracle Tuxedo applications and external Web service applications.

Oracle SALT allows existing Oracle Tuxedo services (inbound) to be easily exposed as Web services without additional programming tasks. It also allows you to create native Oracle Tuxedo applications that access external Web services (outbound) transparently.

Major Web services benefits include:

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

•	Easy, widespread access to applications using Web protocols

•	A cross-platform, cross-language data model (XML) that facilitates developing heterogeneous distributed applications

Figure 1 illustrates how the Oracle SALT gateway is used in the Oracle Tuxedo framework.

Understanding the Oracle SALT SCA Container

Oracle SALT provides an SCA Container for new application development. The SCA container, which is based on standard SCA programming and assembly model, allows customers to focus on business logic without having to learn many middleware APIs. Use of SCA standard allows you to use SCA tools to develop and assemble applications. The SCA container still leverages all the benefits of Oracle Tuxedo infrastructure, such as reliability, availability, scalability and performance.

SCA container also improves interoperability and extensibility of existing and new Oracle Tuxedo applications by making it easier to interoperate with SOA environments.

Figure 2 describes an application based on SCA assembly and programming model. The application contains many services, offered by SCA components. These components include components hosted in an SCA container as well as existing components accessed from SCA components.

Figure 2 SCA Application

Understanding Oracle SALT Web Application Server

Oracle SALT provides an HTTP server plug-in (mod_tuxedo for Apache/Oracle HTTP Server and tux_nsapi for iPlanet) that forwards HTTP requests to Tuxedo services. Replies from Oracle Tuxedo services are then sent back to HTTP clients such as web browsers by the same plug-in.

In addition, Oracle SALT provides a System Server (WEBHNDLR) that is capable of running PHP, Python and Ruby web applications, such as Symfony (PHP), Django (Python) and Rails (Ruby).

HTTP requests can also be handled directly by regular C/C++ Tuxedo servers using the CGI-like format which is counterpart to the HTTP server plug-in

Oracle SALT Web Application server provides the following support:

•	Apache 2 Web Server Plug-in Support

Web Server plug-ins in Apache 2 format, for interfacing Apache HTTP server 2, Oracle HTTP Server or iPlanet Server and Oracle Tuxedo-based web applications.

•	Web Gateway Interface Support

Support of a Web Gateway Interface in order to develop Oracle Tuxedo services that generate dynamic HTML pages.

•	Web Server Plug-in Support

Web Server plug-ins in Apache 2 format, for interfacing Apache HTTP server 2, Oracle HTTP Server or iPlanet Server and Oracle Tuxedo-based web applications.

Oracle SALT Components

Oracle SALT consists of the following major components:

•	Oracle SALT Gateway (GWWS)

•	WSDL Assistant Utilities

•	SCA Container APIs and Utilities

•	Oracle SALT Web Server Plug-ins

Oracle SALT Gateway (GWWS)

The Oracle SALT provided Oracle Tuxedo system server (GWWS), connects with other Web service applications via SOAP over HTTP/S protocol. The GWWS server acts as an Oracle Tuxedo gateway process and is managed in the same manner as general Oracle Tuxedo system servers. Each GWWS server has bi-directional (inbound/outbound) capability. The GWWS server:

•	accepts SOAP requests from Web service applications and issue Oracle Tuxedo native calls to Oracle Tuxedo services.

•	accepts Oracle Tuxedo ATMI requests and issues SOAP calls to Web Service applications.

You can have multiple GWWS instances in one Oracle Tuxedo domain. The same functionality for multiple GWWS instances is provided by specifying the same Oracle SALT configuration to improve throughput and failover protection. You can also group multiple GWWS instances in different configuration files for different purposes.

When the GWWS server boots, it loads the specified SALT configuration file and Oracle Tuxedo service contract information from the Oracle Tuxedo Service Metadata Repository.

The GWWS server also acts as a simple HTTP Web server for WSDL document and XML Schema file download.

WSDL Assistant Utilities

The Web Services Description Language (WSDL) is an XML-based specification that describes a Web service. A WSDL document describes Web service operations, input and output parameters, and how a client application connects to the Web service. Oracle SALT provides two utilities (tmwsdlgen and wsdlcvt) to map Oracle Tuxedo applications and Web Service WSDL descriptions.

WSDL Generator from Oracle Tuxedo Definitions

When using Oracle SALT to publish Oracle Tuxedo services as Web services, you do not need to compose a WSDL document manually; it is automatically generated as part of the SALT Web service development process. The generated WSDL document can be integrated using Web service development tools, or can be published to a UDDI server.

There are two ways to obtain a WSDL document:

•	Use tmwsdlgen (the WSDL document file generating utility).

•	Download the GWWS server generated WSDL document via HTTP(S).

WSDL Convertor to Oracle Tuxedo Definitions

To support external Web Service applications, external WSDL documents need to be converted. The Oracle SALT conversion utility, wsdlcvt, converts external WSDL documents to Oracle Tuxedo specific definition files (SALT Web Service Definition file, Oracle Tuxedo Service Metadata Repository Definition file and FML32 Field Table Definition file).

The SALT Web Service Definition file can be imported into a SALT Deployment file and utilized by a particular GWWS server. The Oracle Tuxedo Service Metadata Repository Definition file and FML32 Field Table Definition file provide service interface descriptions for Oracle Tuxedo client programming.

SCA Container APIs and Utilities

See the Oracle SALT Command Reference Guide.

Oracle SALT Web Server Plug-ins

Oracle SALT dynamic languages system server (WEBHNDLR), takes requests sent by the Web server plug-in (mod_tuxedo or tux_nsapi) and processes them using PHP, Python or Ruby Web applications (no Oracle Tuxedo-specific API required).

•	mod_tuxedo: this module forwards requests from Apache or Oracle HTTP Server to Tuxedo.

•	tux_nsapi: this NSAPI plug-in forwards requests from iPlanet Web Server to Oracle Tuxedo.

Oracle SALT Use Cases

The following sections describe the most common Oracle SALT Web services use cases:

•	Use Case 1: Exposing Native Oracle Tuxedo Services as Web Services

•	Use Case 2: Invoking Web Services from Oracle Tuxedo Applications

•	Use Case 3: Connecting Oracle Tuxedo Domains Using SOAP Protocol

•	Use Case 4: SCA to SCA Communication

•	Use Case 5: SCA Components Calling an Existing Oracle Tuxedo Service

•	Use Case 6: Oracle Tuxedo ATMI Calling SCA Components

•	Use Case 7: Ruby Web Applications

•	Use Case 8: Python Web Applications

•	Use Case 9: PHP Web Applications

Use Case 1: Exposing Native Oracle Tuxedo Services as Web Services

Native Oracle Tuxedo services can be exposed as Web services using standard Web service SOAP protocol. The GWWS server accepts SOAP requests through HTTP/S and then converts them into Oracle Tuxedo ATMI calls. SALT generates a WSDL document that describes the open standard Web service interfaces for Oracle Tuxedo services.The Oracle Tuxedo Service Metadata Repository is used to define Oracle Tuxedo service contract information. This is an “inbound” use case.

Figure 4 illustrates a generic inbound Web service call.

Figure 4 Exposing Oracle Tuxedo Services as Web Services (Inbound)

Use Case 2: Invoking Web Services from Oracle Tuxedo Applications

Web service applications can be imported into an Oracle Tuxedo domain, advertised as Oracle Tuxedo services through the GWWS server, and invoked from Oracle Tuxedo applications. SALT converts and maps each wsdl:operation as a particular Oracle Tuxedo service. The GWWS server advertises the mapped services (called SALT proxy services), and accepts Oracle Tuxedo ATMI requests from Oracle Tuxedo applications.

The Oracle Tuxedo Service Metadata Repository is used to store converted Oracle Tuxedo service contract information and helps Oracle Tuxedo programmers understand what type of Oracle Tuxedo buffers are expected for the imported SALT proxy services. This is an “outbound” use case.

Figure 5 illustrates a generic outbound Web service call.

Figure 5 Invoking Web Services from Oracle Tuxedo Applications (Outbound)

Use Case 3: Connecting Oracle Tuxedo Domains Using SOAP Protocol

Oracle SALT also allows you to connect two different Oracle Tuxedo domains using GWWS servers as an alternative to using /T domain. The GWWS server in the calling domain works in an outbound direction, the GWWS server in the receiving domain works in an inbound direction.

The receiving Oracle Tuxedo domain must propagate the Oracle Tuxedo service definition to the calling Oracle Tuxedo domain. This means that the calling domain Oracle Tuxedo Service Metadata Repository must contain the Oracle Tuxedo service definition file that runs in the receiving domain.

Note:

This should be set up manually. The Oracle Tuxedo Service Metadata Repository infrastructure does not currently provide automatic propagation between Oracle Tuxedo domains.

The WSDL document is not required. Oracle SALT provides simple configurations to allow two GWWS servers to work together for domain connectivity using SOAP protocol without needing to exchange WSDL documents.

Figure 6 illustrates how to use Oracle SALT to connect two domains.

Figure 6 Connecting Two Oracle Tuxedo Domains with SOAP protocol

Two GWWS servers should not be used to create connections within the same Oracle Tuxedo domain, see Figure 7. Also, a single GWWS server cannot connect to itself, see Figure 8.

In either scenario, the GWWS server advertises the same Oracle Tuxedo services which are already advertised by other application servers. This might result in dead-loop service dispatching.

WARNING:

It is strongly advised that you carefully plan and configure your Oracle SALT application to avoid these scenarios.

Figure 8 Single GWWS Server Making a Connection to Itself

Use Case 4: SCA to SCA Communication

Oracle SALT provides an infrastructure that allows developing components that conform to the Services Component Architecture (SCA) specification. These components may interact natively, or leverage the performance and high-availability of the Oracle Tuxedo framework, by communicating using a native ATMI binding, a WorkStation protocol based binding, or a Web-Services binding as shown in Figure 9.

Figure 9 SCA to SCA Communication

Use Case 5: SCA Components Calling an Existing Oracle Tuxedo Service

Newly developed SCA components can interact with existing Oracle Tuxedo ATMI services by using the ATMI binding, as shown in Figure 10.

Figure 10 SCA Components Calling an Existing Oracle Tuxedo Service

  

Use Case 6: Oracle Tuxedo ATMI Calling SCA Components

Conversely, existing Oracle Tuxedo clients can interact with newly-developed SCA components by being exposed with the ATMI binding, as shown in Figure 11.

Figure 11 Oracle Tuxedo ATMI Calling SCA Components

 

Use Case 7: Ruby Web Applications

A Ruby web application created using Rails can run directly inside Tuxedo without any code modification.

Use Case 8: Python Web Applications

A Python Web application created using Django can run directly inside Tuxedo without any code modification.

Use Case 9: PHP Web Applications

A PHP web application created using Symfony can run directly inside Tuxedo server without any code modification.

Configuring Web Services with Oracle SALT

The following steps are used typically when you configure Web services using Oracle SALT:

1.	Configure Inbound Oracle Tuxedo Services

a.	Define Oracle Tuxedo application services using the Oracle Tuxedo Service Metadata Repository.

b.	Compose one or more Oracle SALT Web Service Definition Files (WSDF).

2.	Configure Outbound Web Services

a.	Convert an external WSDL document into Oracle Tuxedo the following components: SALT Web Service Definition file, Oracle Tuxedo Service Metadata Repository Definition file, and FML32 Field Table Definition file.

b.	Resolve potential naming conflicts for the auto-generated service names and FML32 field names.

3.	Load all Oracle Tuxedo Service Definitions into the Oracle Tuxedo Service Metadata Repository using tmloadrepos.

4.	Compose the Oracle SALT Deployment File for both inbound and outbound services.

5.	Add the TMMETADATA and GWWS servers to your Oracle Tuxedo UBBCONFIG file.

6.	Boot the Oracle Tuxedo application.

Invoking Oracle Tuxedo Services Using Web Service Client Toolkits

1.	Client end user downloads the WSDL document file from the GWWS server.

2.	Client end user generates client-side stubcode from the WSDL document file with a SOAP development kit.

3.	Generate client-side program.

4.	Run the client to invoke the Web service with SOAP messages.

Invoking Web Services Using Oracle Tuxedo Programming Interfaces

1.	Create an Oracle Tuxedo client/server program according to the generated Oracle Tuxedo Service Metadata Definition file. The client program can be written in any Oracle Tuxedo supported client-side programming language (C/C++, Java, COBOL, .NET, and so on).

2.	Compile and deploy the Oracle Tuxedo client/server program.

3.	Run the Oracle Tuxedo application to invoke the external Web service applications.
