This manual describes the DataStage Director, the DataStage component that is used to validate, schedule, run, and monitor DataStage server jobs and parallel jobs. For information about how to perform these tasks for DataStage mainframe jobs, refer to the documentation supplied with the mainframe computer.
For a brief explanation resigner server, parallel, and mainframe jobs, refer to “DataStage Projects and Jobs” on page To use this manual you should be familiar with the Windows or Windows XP interface, but no other special skills or knowledge are required. To find particular topics you can: The guide contains links both to other topics within designrr guide, and to other guides in the DataStage manual set. The links are shown in blue. Note that, if you follow a link to another manual, you will dxtastage to that manual and lose your place in this manual.
Such links are shown in italics. Documentation Conventions This manual uses the following conventions: Convention Usage Bold In syntax, bold indicates commands, function names, keywords, and options that must be input exactly as shown. In text, bold indicates keys to press, function names, and menu selections. Italic In syntax, italic indicates information that you supply.

DataStage Documentation DataStage documentation includes the following: This guide describes the DataStage Director and how to validate, schedule, run, and monitor DataStage server jobs.
This guide describes the DataStage Designer, and gives a general description of how to create, design, and develop a DataStage application. This guide gives more specialized information about parallel job design. This guide describes DataStage setup, routine housekeeping, and administration. These guides are also available online in PDF format. You can use the Acrobat search facilities to search the whole DataStage document set. Dessigner online help is also supplied. This is particularly useful when you have become familiar with DataStage, and need to look up specific information.
But that data may be stored in different formats in different types of database. Some data sources may be dormant archives, others may be busy operational databases. Extracting and cleaning data from these varied sources has always been time-consuming and costly — until now.
DataStage makes it simple to design and develop efficient applications that make data warehousing a reality where it was impossible before. What Is a Data Warehouse? A data warehouse is a central database containing copies of data from all the operational sources and archive systems in an organization.

But the database does not have to be large. Instead of storing details of every transaction, order, or set of sales figures, the data warehouse stores totals, averages, area figures, and so on. This data is structured to make it easy to query and to generate reports.
Inside the data warehouse you can perform analyses that would be impractical on a working database. This means that anyone who needs access to the data gets all the information they want, and only the information they want.
The data warehouse can be created or updated at any time, with minimum disruption to working systems. Why Do I Need One? Working databases are busy. By transferring working data into a data warehouse, you can take snapshots of what is going on. Also, working databases contain dirty data — records in ascenrial formats, with key values missing or out of range, and so on.
Asfential a fast-moving working database it is difficult to trap mistakes or incomplete entries. Using DataStage, you can cleanse data before loading it into a data warehouse, ensuring that your business decisions are based only on valid information. As well as a working database, you may have archive systems or incompatible data sources that you have inherited. These may be static, but inaccessible because their format is different from your working system. You can use DataStage to transform this data into compatible formats that can be stored in the data warehouse.

What Does DataStage Do? DataStage comes in between your data and your data warehouse.
DataStage jobs process the data to meet your needs, including: This means you have to store much less data, which is quicker and easier to access.
How Is DataStage Packaged? The server holds the data while it is being processed. The catastage is the interface to DataStage that is used for designing and running jobs, or managing the data in the Repository. The client components include: Server jobs are compiled into executable programs that are scheduled by the DataStage Director and run by the DataStage Server. Mainframe jobs are downloaded from the Designer to mainframe computers, where they are compiled and run by mainframe tools.
The client and server components ascntial depend on the edition of DataStage you have purchased. DataStage is packaged in two ways: When you start a DataStage client you are prompted to attach to ascemtial project.
DATASTAGE TUTORIAL,GUIDES AND TRAINING
Each project contains DataStage jobs and the components required to develop or run them. DataStage jobs are made up of individual stages. A stage represents a data source or a process. For example, one stage may catastage data from a data source, while another transforms it.
The data required at each stage and how it is handled is specified in the job design.
When the job is run, the processing described in the job design is performed. Variable parameters such as file names, dates, and so on, can be specified when the job is run.
DataStage jobs can be exported for use on other DataStage systems. DataStage supports three types of job: Compilation designfr a server job creates an executable that is scheduled and run from the DataStage Director. The job is compiled and run on the mainframe computer under the control of native mainframe software.
A job sequence allows you to specify a sequence of DataStage jobs to be executed, and actions to take depending on results. It is the starting point for most of the tasks a DataStage operator needs to do in respect of DataStage jobs. Note DataStage mainframe jobs run on a mainframe computer, and use mainframe-specific tools. These jobs are not visible in the DataStage Director. In this manual the term job therefore refers to DataStage server and parallel jobs only.
For information about running DataStage mainframe jobs, consult the documentation supplied with your mainframe software. This chapter describes the interface to the DataStage Director and how to use it, including: The Attach to Project dialog box appears: This is the name of the system where the DataStage Server is installed.
This is your user name on the server system. The User name and Password fields gray out and you log on to the server using your current Windows account details. Warning Think carefully before using the Omit option to log on to DataStage.
