Double-click on the DB2 Connector that represents the input source. DB2's architecture offers relational and XML data management support The scenarios in this article series rely on DB2's pureXML capabilities, which include optimized storage of XML data in its native hierarchical Maintaining full XML data in the data warehouse allows users to immediately access important business data that wasn't previously shredded into a relational format. The Home_address list can contain possibly multiple addresses. http://vgadownload.com/error-the/error-the-communication-link-is-lost.html

To open the DB2 Connector that represents the target table, double-click on its icon.In the Properties tab, specify the appropriate connection information. The Group To List projection can only apply to a group node (see the definition in the data model section) and it turns the group into a list of size one. dW Answers Ask a technical question Explore more technical topics Tutorials & training to grow your development skills Back to top static.content.url=http://www.ibm.com/developerworks/js/artrating/SITE_ID=1Zone=Information Management, XMLArticleID=421809ArticleTitle=IBM InfoSphere DataStage and DB2 pureXML, Part 1: Doing so requires adding two new stages to the existing job.

Operational data stored in DB2 pureXML serves as input to the data warehouse This data model represents a common scenario in which portions of XML data are often "shredded" into a Select the ACCOUNT table from the list of available tables for this schema.Leave all options unchecked, including the "XML Columns as LOBs" option.

The properties of the source DB2 Connector stage need to be edited to reflect appropriate information about this input table.

Since we use DB2 to manage both operational data and warehouse data, we could have elected to use built-in DB2 technologies to perform much of the ETL work. The document root window of the XML parser stepIt is important to note that only XSLT stylesheets that return a well-formed XML document can be used by the assembly.Back to topPerformance Error in Derivation Rule Processing VA01 Stage variable in contraints Reject a Column if It Has '#', '(', ')' Or Alphabetical Character Problem while loading the Xml file Conversion Warning in You may update your IBM account at any time.

Both methods are described in the XML stage documentation as Example 2 and Example 3 under the Examples of Transforming XML data. Click on the Columns tab, and select Load at the bottom of the pane.A window appears with table definitions. dW Answers Ask a technical question Explore more technical topics Tutorials & training to grow your development skills Back to top static.content.url=http://www.ibm.com/developerworks/js/artrating/SITE_ID=1Zone=Information Management, XMLArticleID=642734ArticleTitle=Using the XML transformation capabilities in IBM InfoSphere weblink Do this for every column except the ID column (which is extracted from a relational column in the source TPOXADMIN.ACCOUNT table).

The downside of this method is that the LOB data can only be moved from one connector to another and cannot be transformed in the job (as only the reference is The List To Group projection helps in mapping the entire employee information to a single list in the output step.In this job, the assembly comprises the XML parser, switch, and output When an XQuery is used, the connector does not support passing the XML result by reference due to difficulties in constructing a LOB locater. Support for DB2 DPF (Database Partitioning Feature).

In this scenario, the filtering has to be done on the address list. Check This Out However, we know that Home_address list has only a single address since the original address list contains only a single address with "H." Hence, there is no information loss when it Notice that in both cases, the assembly is not aware of the partitioning, or in other words: It does not need to be configured differently for the parallel execution.Parallelizing the execution Specify the XPath expressions that DataStage should use to extract information from the input XML data (shown in Figure 12).

With XML Input, you can: Extract data using standard XPath expressionsUse XML Schemas and optionally validate XML dataSupport complex transformations using custom stylesheetsSupport multiple output links using different data setsHandle errorsFigure Simple parsing and composition scenarios are usually intuitive and do not require deep understanding of the assembly concepts or of XML schema in general.The assemblyThe assembly hierarchical data modelThe assembly data

In ordinary batch jobs, the composer step creates only a single file in this setting. However in wave-enabled jobs, the composer step creates a single file for each wave.Back to topThe mapping tableThe mapping table is a common construct that allows you to map one hierarchical The first time you sign into developerWorks, a profile is created for you. http://vgadownload.com/error-the/error-the-communication-link-is-lost-tkfileexplorer.html She has extensive experience with the DataStage XML Stage and is now working on the WebServices Stage.

Modify the output structure from this job stage as follows (to match the content of Figure 8): Specify a length of 5000 bytes for the FULLRECORD column. This series uses the XML Input and XML Output stages. Describing and discussing present attempts at modelling human language processing by using linguistic disorders and pathologies as a data base.

Figure 8. The assembly data model is a simplification of the XML schema model. Listing 7. Since Symbol occurs in every Position element, the stage produces a record for each Position element.

Add a Transformer stage to the job. (This stage will split a single XML element value into two values that will populate two different columns in the target table.)

The Chunk option in the document root window of the parser stepNotice that when the Chunk operation is performed, the output tree contains an item whose type is XML.

A new set of tabs appears.

In addition, DataStage provides a number of transformation and cleansing functions beyond those found in DB2. Some components may not be visible.
