Web Service Access to Oracle DataLens Servers Interface Guide
Release 11g R1 (11.1.1.6)
E29146-01
August 2012
This document describes the Oracle Enterprise Data Quality for Product Data Web Access to Oracle DataLens Servers and contains the following:
Web service access is provided to the Oracle DataLens Server as a Document-Literal Web Service. The following sections describe how to set up this access and the Web Service Operations that you can use to interface with Enterprise DQ for Product (EDQP) Data Service Applications (DSAs) including examples.
To integrate with an Enterprise DQ for Product DSA as a Web Service, you need software that will interface with the Oracle DataLens Web Services. There are a number of tools available to generate this software from a Web Services Description Language (WSDL) document, which is an XML format for describing network services. You can view the WSDL for the Oracle DataLens Web Services by using an Internet browser.
Browse to the following Web site:
http://server:port/datalens/ws/Processor?wsdl
Where server:port is the hostname and port number of your Oracle DataLens Server.
This displays the WSDL document, which can be saved by right-clicking in the document in the browser, selecting View Source, and then saving the file from within your browser. For instance, the file can be saved as Processor.wsdl.
There is a single Service called "ProcessorService", which uses a PortType (Interface) called "Processor".
The following three Oracle DataLens Web Services Operations can be used to process data and communicate with a DSA by creating a job:
ProcessorListThis requires an input array of strings, or multiple lines of data, and returns an output array of strings. One DSA job is created.
ProcessorOneLineThis requires a single string of input, or one line of data, and returns a single string of output. If you have several lines of data, use ProcessorList to process them because a single DSA job is created rather than the multiple DSA jobs that would be created using the ProcessorOneLine operation for each line of data. For example, if you have four lines of data to process, the ProcessorList creates one DSA job while the ProcessorOneLine creates four separate DSA jobs.
ProcessorDBThis requires a database query (defined in the Transform Map) and returns a job Id of the DSA Job that handled the request. The output is assumed to be a database update, e-mail, or FTP. One DSA job is created.
Reviewing the EDQP WSDL will help you to understand what operations and parameters can be used to communicate with DSAs.
Simple Object Access Protocol (SOAP) is used to communicate with DSAs. For more information about SOAP, see the W3C SOAP 1.1 Web site:
You must provide the exact input fields that are defined in the DSA to ensure proper operation and avoid errors. For example, if the input nodes in the DSA are Id, Category, and Description, you must provide all three fields in your SOAP processing operation.
You must separate input fields using a defined separator; the tab character "î" is recommended. For example, using the tab character to separate the Id, Category, and Description input fields:
<lineOfData>3î2334îres, 37ohm, 39watt, 30%</lineOfData>
The best practice is to define all of the operation parameters (even those that may be labeled as optional) to avoid errors. The EDQP WSDL and the DSA define the necessary parameters not the SOAP UI you are using; some SOAP UIs erroneously mark parameters as optional as in the examples in the following sections.
The SOAP request structure is the same for each type of request though some of the parameters may not apply. For example, processListRequest and processOneLineRequest do not use the dbparameters parameter; processDBRequest does not use line or linesofdata parameters. The parameters used are dependent on the operation request.
Additionally, defining all parameters allows the most information possible to be related to the DSA job, and then reviewed and verified in the Oracle DataLens Server Administration Web Page.
processListRequest and processOneLineRequest OperationsThe difference between these two operations is that processListRequest takes an array of lines and processLineRequest takes a single line of data as a string. The transformed data is returned. This call is synchronous. The parameters are as follows:
dsaNameThe name of the DSA to run on the Oracle DataLens Server.
line or linesOfDataOne line or multiple lines of input or output data respectively.
dbParametersNot used.
priorityThe priority the DSA job will be given on the Oracle DataLens Server for processing; the default is Medium. The priority is set numerically as follows:
3 for High2 for Medium (the default)1 for LowruntimeLocaleA run time locale must be entered; the default locale of en_US should be entered if not known.
fieldSeparatorCharA character that will be used to separate fields; the tab character "î" is recommended.
applicationThis application name initiated the client request to the server. The application name must be a valid LDAP entry in the WebLogic Server to avoid a failure. This name is used to accumulate server statistics on the Oracle DataLens Server Administration Web Page.
descriptionA description of a particular job and relates to a DSA Job ID.
The Oracle DataLens Server Administration Server Job Status Web page shows the DSA Job ID for both the processListRequest and processLineRequest operations as in Figure 1.
Additionally, the priority parameter that was set is displayed in the Priority column.
The following Oracle DataLens Server Administration Server Job Detail Web page illustrates the operation parameters supplied in the processListRequest operation as in Figure 2.
The following sections provide examples of request and response operations for both the processListRequest and processLineRequest operations:

processDBRequestThis call takes the database parameters as input and returns the DSA Job ID. This call is asynchronous. The parameters are as follows and are the same as described in "processListRequest and processOneLineRequest Operations":
dsaName dbParameters priority runtimeLocale fieldSeparatorChar application description
However, the dbParameters parameter is the value that is input to the DSA database query and is related to the DSA job run.
The following sections provide example request and response operations for the processDb operation:

The return value of the preceding processDb call is the DSA Job ID, in this case 16. This job reads data from the database and updates other fields in the database as in Figure 3.
