B.

Add data stores to the package, set Datastores steps to Journalizing Datastore, and select the Unlock Subscriber and Purge Journal check boxes.

C.

Add a model to the package, set the Model step to Journalizing Model, and select the Extend Window and Lock Subscriber check boxes.

It must be used by ETL developers to develop ODI processes.

Your project requires a loop through the same package logic 24/7. You must be able to purge those executions when required. How do you accomplish this? (Choose the best answer.)

A.

Link the last step of the package to its first step to create an infinite loop.

B.

Create a scenario from the package, add the scenario as the last step in the package, run it asynchronously, and then save and regenerate this scenario.

C.

Create a scenario from the package, add the scenario as the last step in the package, run it asynchronously, and then save.

D.

Drag the package to the last step in the package, run it asynchronously, and then save.

You are designing a load plan in which you must create multiple branches based on the value of a variable. How do you accomplish this by using Load Plan Editor? (Choose the best answer.)

A.

Add a case step and drag the variable into the case step.

B.

Create a scenario from the variable and add the scenario to the load plan to create a case step.

C.

Add a case step in the load plan and select a variable in the wizard.

D.

Drag the variable into the load plan and define a case step.

Identify two correct statements about reusable Mappings. (Choose two.)

A.

They can have generic input and output signatures.

B.

They contain both a Logical and Physical Mapping design.

C.

They can be used within regular Mappings.

D.

They can be executed directly.

E.

They can be shared across projects.

Your customer wants a project in ODI, which contains a user function, to translate commands with different syntax for different technologies but with the same functionality.

How can you achieve this? (Choose the best answer.)

A.

The project must be explicitly mapped within an ODI mapping.

B.

A customize knowledge module is needed.

C.

An ODI procedure must be associated with it.

D.

It can be defined for every technology listed in the topology.

You want to ensure that the Physical Mapping Design cannot be modified even if the Logical Design of the Mapping is changed. What sequence of steps must you follow to achieve this? (Choose the best answer)

Create a custom KM to handle this by using ODI variables defined at the Topology level to create unique temporary object names.

B.

Use variables in the Logical Design of the Mapping to create unique temporary object names.

C.

Create a custom Knowledge Module (KM) to handle this by using ODI variables to create unique temporary object names.

D.

Select the Use Unique Temporary Object Names check box at the Physical Design level.
