You are defining a data store in ODI metadata and want to add a primary key even if it does not physically exist on the related database catalog. How can you accomplish this? (Choose the best answer.)

Select one or more of the following:

  • You can add a primary key even if it does not physically exist on the related database catalog, by adding constraintson the data store.

You want to deploy the generated code manually in a source or target server, before executing a mapping in ODI. How can you accomplish this? (Choose the best answer.)

Select one or more of the following:

  • You need not deploy the generated code manually in a source or target server. ODI Agent coordinates the execution of commands prepared for the job, and executes them on the correct server.
