Throughout dxtapower book, you will see just how important these features are and how to leverage them. Click Finish to generate the artifacts. The appliance is green, which represents its primary function: After creating all the statements, the SQL Scripts folder should look similar to the one in Figure 8.
The Data Source Configuration Parameters tab allows you to specify additional connection parameters. In order to keep the setup simple, copy all artifacts into the local DataPower file system. A very common format for Web service is XML. Later, this tutorial uses a simple example to show you how to use Data Studio Developer to create a Data Web Service, how to generate the artifacts for DataPower, and how to deploy the service on a DataPower XI50 appliance.
This tutorial focuses on DataPower as a transformation and protocol conversation engine to transform Web service requests into database calls and the result back into service responses to implement a data access service. This chapter is from the book. All service configurations have a front-end and tutorual configuration as well as a processing tuorial which defines one or more processing rules. Base this project on a connection to a DB2 sample database.
It should be used in-line in the network topology, not as a co-processor hanging off a particular server although this latter usage is how the appliances were first designed. View image at full size.

For example, it may be configured to do validation and transformation of XML before it reaches or for traffic flowing between the backend servers. The majority of this book focuses on the XI50, as it is a superset of the other two models. A Web rutorial folder contains the service metadata information in the.
Figure 1 shows this transformation process:.
Certain attributes should come to mind:. We are speaking about the tuforial configuration—there are options available, such as adding a Hardware Security Module, which could alter the outward physical profile. A popular usage is to receive XML responses from backend servers and transform those into HTML before continuing the response to the client.
You can locate the procedure by navigating to the Stored Procedure folder under the appropriate schema in the database connection in the Data Source Explorer view:.
Select New Web Service Now you need to copy the generated artifacts over to the DataPower box. Alternatively, you can also use the SQL builder to assemble the statement.
In case DataPower was selected as the runtime environment, you will also find an artifacts folder. The DataPower appliance only requires one of those.

After all files are selected, click Upload to transfer them to the DataPower box. There are also replaceable fan tutoriaal, batteries, power supplies, and compact flash cards or hard drives.
Now that you understand how to copy the artifacts, you can see how to configure the service. The Data Web Services tooling lets you adjust the result set schema by executing the procedure and taking the schema information from the returned result set metadata. This model is often found in the DMZ, as its security capabilities are extensive.
A database is not considered to be a back-end system for DataPower. All you need to do is add a new processing rule to the policy. After the execution, you can click Finish on the Edit Operation dialog. Those artifacts can now be deployed on a DataPower XI50 appliance. Comments Sign in or register to add and subscribe to comments. Instead of providing a real back-end system with the configurations, we use a loopback configuration which turns an incoming request into a response. A policy defines a set of one or more processing rules.

You can re-use the XSL Accelerator that you setup previously. This executes the procedure, and the metadata from the returned result set can be analyzed. We use this program to dwtapower our examples. To add a new file to the upload list, click the Add button. After a service has been defined, artifacts for a specific runtime environment can generated.
This is due to several factors, the primary ones being total cost of ownership TCOreturn on investment ROIperformance, integration, ease of use, and security. The generated artifacts consist of the WSDL file of tutofial service as well as a set of XSL scripts defining the mapping between service requests and database calls. Therefore, XSL is used to transform daapower requests into database calls and back. In there you will find one directory for every Web service defined in your Data Development Project.
A transformation is defined by a set of rules which determine how an input is mapped to an output.
