In your ETL application design you have found several areas of common processing requirements in the mapping specifications. These common logic areas found include: code validation lookups and name formatting. The common logic areas have the same logic, but the jobs using them would have different column metadata. Choose the action that gives you the best reusability design to effectively implement these common logic areas in your ETL application?
2.
When optimizing a job, Balanced Optimization will NOT search the job for what pattern?
3.
You are assigned to correct a job from another developer. The job contains 20 stages sourcing data from two Data Sets and many sequential files. The annotation in the job indicates who wrote the job and when, not the objective of the job. All link and stage names use the default names. One of the output columns has an incorrect value which should have been obtained using a lookup. What could the original developer have done to make this task easier for maintenance purposes?
4.
A job design consists of an input Row Generator stage, a Filter stage, followed by a Transformer stage and an output Sequential File stage. The job is run on an SMP machine with a configuration file defined with three nodes. The $APT_DISABLE_COMBINATION variable is set to True. How many player processes will this job generate?
5.
Which partitioning method requires a key?
6.
A job design consists of an input Row Generator stage, a Sort stage, followed by a Transformer stage and an output Data Set stage. The job is run on an SMP machine with a configuration file defined with four nodes. The $APT_DISABLE_COMBINATION variable is set to True. How many player processes will this job generate?
7.
The data going into the target Sequential Files stage is range-partitioned and sorted. Which technique method would be the most efficient to create a globally sorted target sequential file?
8.
What is the result of running the following command: dsjob -report DSProject ProcData
9.
On the DataStage development server, you have been making enhancements to a copy of a DataStage job running on the production server. You have been asked to document the changes you have made to the job. What tool in DataStage Designer would you use?
10.
You want to find out which table definitions have been loaded into a job, and specifically which stages of the job they has been loaded into? How will you determine this?
