A new DataStage Repository Import window will open. This import creates the four parallel jobs. Inside the folder, you will see, Sequence Job and four parallel jobs.

Step 6 To see the sequence job. It will show the workflow of the four parallel jobs that the job sequence controls. It will set the starting point for data extraction to the point where DataStage last extracted rows and set the ending point to the last transaction that was processed for the subscription set.

Then passes sync points for the last rows that were fetched to the setRangeProcessed stage. So, the DataStage knows from where to begin the next round of data extraction Step 7 To see the parallel jobs. It will open window as shown below. It contains the CCD tables. In DataStage, you use data connection objects with related connector stages to quickly define a connection to a data source in a job design.

Step 3 You will have a window with two tabs, Parameters, and General. Click Open. In the designer window, follow below steps. Step 3 Click load on connection detail page. This will populate the wizard fields with connection information from the data connection that you created in the previous chapter.

Step 4 Click Test connection on the same page. You can see the message "connection is successful". Click Next. Step 5 Make sure on the Data source location page the Hostname and Database name fields are correctly populated.

Then click next. 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. 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. A data browser window will open to show the contents of the data set file.

For that, we will make changes to the source table and see if the same change is updated into the DataStage. Step 1 Navigate to the sqlrepl-datastage-scripts folder for your operating system. Run the startSQLApply. Step 3 Now open the updateSourceTables. Step 4 Open a DB2 command window. Step 5 On the system where DataStage is running.

When you run the job following activities will be carried out. The two DataStage extract jobs pick up the changes from the CCD tables and write them to the productdataset. You can check that the above steps took place by looking at the data sets.

Step 6 Follow the below steps, Start the Designer. In the stage editor. Click View Data. Accept the defaults in the rows to be displayed window and click OK. The dataset contains three new rows. The easiest way to check the changes are implemented is to scroll down far right of the Data Browser. You can do the same check for Inventory table.

Summary: Datastage is an ETL tool which extracts data, transform and load data from source to the target. It facilitates business analysis by providing quality data to help in gaining business intelligence. DataStage has four main components, Administrator.

This dialog box is also displayed if you click Setup… in the Print dialog box. The client is the interface to DataStage that is used for designing and running jobs, or managing the data in the Repository. If you want to monitor more than one job at a time, you can display more than one Monitor window. Ascential Datastage Director Guide Pdf When the job runs it will look in the local handler if one exists for each message to see if any rules exist for that message type. Select this to show details for each instance of a parallel datastagd that has been partitioned between processors — see page When a job has a status of Stopped or Aborted, you must reset it before running the job again. The context will always be listed as Unavailable if the Show All option button is selected. Extracting and cleaning data from these varied sources has always been time-consuming and costly — until now.
