Runtime topologies for distributed transaction jobs Appendix B. Standard practices summary Appendix C. Step 6 On Schema page. The selection page will show the list of tables that are defined in the ASN Schema.
It has the detail about the synchronization points that allows DataStage to keep track of which rows it has fetched from the CCD tables.
Click import and then in the open window click open. You need to modify the stages to add connection information and link to dataset files that DataStage populates.
Stages have predefined properties that are editable. Step 1 Browse the Designer repository tree. To edit, right-click the job.
The design window of the parallel job opens in the Designer Palette. Step 2 Locate the green icon. This icon signifies the DB2 connector stage. It is used for extracting data from the CCD table. Double-click the icon.
A stage editor window opens. Step 3 In the editor click Load to populate the fields with connection information. To close the stage editor and save your changes click OK. Locate the icon for the getSynchPoints DB2 connector stage.
Other Language Versions
Then double-click the icon. Step 5 Now click load button to populate the fields with connection information. Then select the option to load the connection information for the getSynchPoints stage, which interacts with the control tables rather than the CCD table. Name this file as productdataset.
DataStage will write changes to this file after it fetches changes from the CCD table. Data sets or file that are used to move data between linked jobs are known as persistent data sets. It is represented by a DataSet stage.
It will open another window. On the right, you will have a file field Enter the full path to the productdataset. You have now updated all necessary properties for the product CCD table. Close the design window and save all changes. NOTE: You have to load the connection information for the control server database into the stage editor for the getSynchPoints stage. Then use the load function to add connection information for the STAGEDB database Compiling and running the DataStage jobs When DataStage job is ready to compile the Designer validates the design of the job by looking at inputs, transformations, expressions, and other details.
When the job compilation is done successfully, it is ready to run. We will compile all five jobs, but will only run the "job sequence". This is because this job controls all the four parallel jobs. Then right click and choose Multiple job compile option. Step 3 Compilation begins and display a message "Compiled successfully" once done.
Step 5 In the project navigation pane on the left. This brings all five jobs into the director status table.

Once compilation is done, you will see the finished status. Then click view data.
Step 8 Accept the defaults in the rows to be displayed window. Then click OK.SQL statements in Database stages can be tuned for performance.
Then Restart DSEngine. Transformer Stage always generates C-code, which is then compiled to a parallel component.
