Introduction: Verifying the requirements of DataStage operations Today, companies are implementing information-centric projects to transform their businesses and achieve cost savings. Many data integration or information integration applications or processes contain ETL and serve as one of the components. Typically, an ETL process (unit of work) is designed to perform the following tasks: Extraction: Extracts data from the source system and collate

Datastage obtains the number of records inserted into the target table by analyzing logs. This is only a bad method, and there may be better and easier methods. This method requires that the existing log information be deleted before each job is run. Otherwise, the correct number of records cannot be counted. Of course, after the job is run, you can back up the logs of this job to the server disk in shell. 1. Log cleanup settings Log on to

one of the guiding principles of DataStage Job Optimization: Optimization of algorithms. Optimization of any program, 1th first is the optimization of the algorithm. Of course, this is not only limited to the optimization of computer programs, in real life can be reflected in this point everywhere. All roads lead to Rome, and there are many ways to accomplish anything. And the method of course has the advantage and inferior, has the inefficiency and t

General description With the development of Enterprise Informatization, a large number of enterprises are setting up a business intelligence system based on the characteristics of their own industry to guide business operation. The business intelligence system with reasonable design and efficient operation plays a more and more important role in the business decision-making. IBM Infosphere Information Server serves as the basis for an extensible enterprise Information architecture that meets t

Recently in the study of IBM's DataStage 8.5, Win7 installed DataStage when the tragedy of a few days, fortunately still loaded. By the way, mark the problems encountered in the course of self-study and make it easier to read later. Background: I do exercises with reference to DataStage's official English practice materials. This machine only installs the DataStage
