Specify the following information in the dsenv file:Д®nvironment variables for the database client software Database home location Database library directory The default directory is/opt/IBM/InformationServer/Server/DSEngine.

$DSHOME identifies the InfoSphere DataStage installation directory. For a connection that uses a wire protocol driver, you do not have to modify thedsenv file.PROCEDUREДЎ. Back up the dsenv file before you edit it. You must be logged in as an InfoSphere DataStage administrator with the operating system credentials on the server for the InfoSphere DataStage administrator. This lets IBM InfoSphere DataStage inherit the correct environment for ODBC connections.BEFORE YOU BEGIN

For some ODBC connections, plug-ins, and connectors, and for interactions with external applications such as IBM WebSphere MQ, you must add environment variables to enable interactive use of ODBC drivers to make a connection to an ODBC data source. Interactive users, other programs, and scripts can use the dsenv file.

The Complex Flat File stage does not support reference lookup capability or input links.Posted by lokeb4u at 11:23 AM 1 commentsД®mail ThisBlogThis!Share to TwitterShare to FacebookД¬onfiguring the dsenv fileThe dsenv file contains a series of shell arguments that are used when the engine starts. Having more than one output link causes a save or load sequence each time you change tabs. This dramatically improves the performance of the GUI when loading, saving, or building these columns. When using the Complex Flat File stage to process a large number of columns, for example, more than 300, use only one output link in your job. An output link specifies the data you are extracting, which is a stream of rows to be read. The Complex Flat File stage supports multiple outputs. Complex flat files can also include legacy data types.OUTPUT LINKS This filtering process results in performance gains since the stage no longer parses and processes hundreds of columns if you only need a few. You can select a subset of columns from a large COBOL File Description (CFD). The metadata can be flattened into a normalized set of columns at load time, so that no arrays exist at run time.SELECTING SUBSETS OF COLUMNS You can ignore GROUP data columns that are displayed as raw data and have no logical use for most applications. You can easily load, manage, and use repeating groups and internal record structures such as GROUP fields and OCCURS. You can also combine these record groupings, and in the case of repeating data, you can flatten nested OCCURS groups.MANAGING REPEATING GROUPS AND INTERNAL STRUCTURES You can use multiple record types to achieve this hierarchical structure.RECOGNIZING A HIERARCHICAL STRUCTUREДЇor example, use records with various structures for different types of information, such as an 'E' record for employee static information, and a 'S' record for employee monthly payroll information, or for repeating groups of information (twelve months of revenue). It is physically flat (that is, it has no pointers or other complicated infrastructure), but logically represents parent-child relationships. A complex flat file has hierarchical structure in its arrangement of columns. Complex Flat File StagesThe Complex Flat File stage lets you convert data extracted from complex flat files that are generated on an IBM mainframe.
