What is a values file in DataStage?

Answer. Using a value file in a parameter set allows you to set values of a parameter dynamically. For Example: Job A updates the value file. Job B uses a parameter set that points to that value file.

How do you set parameters?

What are environment variables in DataStage?

Environmental variables are project level parameters which are typically used across projects. The advantage to environmental variables is that they can be set at the project level and all associated jobs in that project will automatically use the value.

How do I run a sequence job in DataStage?

After you create a sequence job, you schedule it to run using the InfoSphere DataStage Director client, just like you would with a parallel job or server job. The sequence job is listed in the InfoSphere DataStage repository and in the InfoSphere DataStage Director client.

Which commands are used to import and export the DataStage jobs?

Purpose. Use the DataStage command option with the istool export command to export IBM® InfoSphere® DataStage® and QualityStage® assets to an archive file on the local file system.

What is meant by params?

What is Apt_dump_score in DataStage?

Whether InfoSphere DataStage inserted extra operators in the flow. The degree of parallelism each operator runs with, and on which nodes. Information about where the data is buffered.

Which environment variable must be used to identify the hostname for the engine node in DataStage?

What are the stages you used in the job sequence?

Use the Job Activity stage to specify information about the job that the job activity runs. Use a Nested Condition stage to further branch the execution of a sequence job, depending on a condition. Use the Notification stage to specify information about an email notification activity.

What are the ways to optimize DataStage jobs?

To optimize an InfoSphere DataStage job, do the following steps:

• Start the Designer client and attach to the project that contains the job.
• Open the job that you want to optimize.
• Set the options and properties that control optimization.
• Optimize the job.
• View the optimization log.
• Save the optimized job as a new job.

Can I add additional job parameters to a running IBM DataStage job?

When a IBM® InfoSphere® DataStage®job starts, all the necessary job parameters must be defined. You cannot add additional parameters to a running job.

How to use parameters in a file?

Where are the Infosphere® DataStage®server parameter sets stored?

Parameter sets are stored as files in the InfoSphere® DataStage®server installation directory and are available to use in your job designs or when you run jobs that use these parameter sets. If you make changes to a parameter set object, the changes are reflected in job designs that use this object when the job is compiled.

How do I create and use a value file in DataStage?

How do I create and use a value file within a parameter set in DataStage? Using a value file in a parameter set allows you to set values of a parameter dynamically. For Example: Job A updates the value file. Job B uses a parameter set that points to that value file.
