What is DataStage director used for?
The Director is the client component that validates, runs, schedules, and monitors jobs on the engine tier. The Director client is the starting point for most of the tasks an IBM® InfoSphere® DataStage® operator needs to do in respect of jobs.
Which is type of view in DataStage director?
DataStage Director has three view options: The Status view displays the status, date and time started, elapsed time, and other run information about each job in the selected repository category. The Schedule view displays job scheduling details. The Log view displays all of the events for a particular run of a job.
What are the components of DataStage?
Three components comprise the DataStage server:
- Repository. The Repository stores all the information required for building and running an ETL job.
- DataStage Server. The DataStage Server runs jobs that extract, transform, and load data into the warehouse.
- DataStage Package Installer.
What is DataStage designer?
The DataStage Designer is the primary interface to the metadata repository and provides a graphical user interface that enables you to view, edit, and assemble DataStage objects from the repository needed to create an ETL job. An ETL job should include source and target stages.
When should I use DataStage?
DataStage makes use of graphical notations for constructing data integration solutions. It can integrate all types of data, which includes big data at rest or in motion, and on platforms that may be distributed or mainframe in nature. DataStage is also known as IBM InfoSphere DataStage.
How do you deploy a DataStage job?
You can manage your InfoSphere DataStage jobs and associated assets in your source control system….Deploy
- Define a package to specify the assets to deploy.
- Build the package to produce a package file.
- Copy the package file to the target system if necessary.
- Deploy the package on the target system.
What is partitioning in DataStage?
Data partitioning and collecting in Datastage. Partitioning mechanism divides a portion of data into smaller segments, which is then processed independently by each node in parallel. It helps make a benefit of parallel architectures like SMP, MPP, Grid computing and Clusters.
What is hash file in DataStage?
The data in Datastage can be looked up from a hashed file or from a database (ODBC/ORACLE) source. Lookups are always managed by the transformer stage. A Hashed File is a reference table based on key fields which provides fast access for lookups. They are very useful as a temporary or non-volatile program storage area.
What are DataStage jobs?
A graphical design interface is used to create InfoSphere DataStage applications (known as jobs). Each job determines the data sources, the required transformations, and the destination of the data. Jobs are compiled to create parallel job flows and reusable components.
How are DataStage jobs organized?
Jobs and their associated objects are organized in projects. DataStage administrators create projects using the Administrator client. When you start the Designer client, you specify the project that you will work in, and everything that you do is stored in that project.
How do I create a DataStage job?
Perform the following steps to build a job:
- Define optional project-level environment variables in DataStage Administrator.
- Define optional environment parameters.
- Import or create table definitions, if they are not already available.
- Add stages and links to the job to indicate data flow.
Which is a typical application of DataStage?
DataStage (DS) is an ETL tool that can extract data, transform it, apply business principles and then load it to any specific target. It is a part of IBM’s Information Platforms Solutions suite and also that of InfoSphere. DataStage makes use of graphical notations for constructing data integration solutions.
