Question 69

Question
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.)
Answer
  • 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.
  • You must deploy the generated code manually in a source or target server. You must then compile the generated code and then double-check if the code prepared for the development server is the same as the code for the production server.
  • You need not deploy the generated code manually in a source or target server. ODI prepares a package for the development environment.
  • You must deploy the generated code manually in a source or target server. You must copy all procedures generated into the development, test, and production servers.

Question 70

Question
You need to create a Model that works with multiple underlying technologies. How must you proceed? (Choose the best answer.)
Answer
  • This works only for Oracle and Informix.
  • This works only for Oracle and MySQL.
  • Create a new generic technology to support it.
  • Use the out-ofthe box Generic SQL technology.

Question 71

Question
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.)
Answer
  • The project must be explicitly mapped within an ODI mapping.
  • A customize knowledge module is needed.
  • An ODI procedure must be associated with it.
  • It can be defined for every technology listed in the topology.

Question 72

Question
You are working with delimited flat files and want to enforce a primary key on a flat file by using a Check Knowledge Modules (CKM). However, you encounter an error. Why did this happen? (Choose the best answer.)
Answer
  • It is not possible to enforce constraints on some technologies such as flat files and Java Messaging Service (JMS) queries.
  • It is not possible to enforce constraints on any technology.
  • It is only possible to forward-engineer it to the flat file definition.
  • It is possible to enforce a primary key on a flat file by using a CKM; however, you have to save it as a fixed file.

Question 73

Question
Which two objects can be dragged to a Mapping? (Choose two.)
Answer
  • Variables
  • Datastores
  • Knowledge Modules
  • Reusable Mappings

Question 74

Question
A Mapping that uses CDC does not load any source data and you want to check the SNP_CDC_SET table to find out the current window ID. In which database schema must you look to find this table? (Choose the best answer.)
Answer
  • the schema hosting the Work repository
  • the schema hosting theWork schema of the default schema defined for your source data server
  • the schema hosting the Staging Area
  • SYS

Question 75

Question
How does the data flow when moving records between two servers by using Database Links and an Agent installed on a middle-tier server? (Choose the best answer.)
Answer
  • from the source database into flat files that are then loaded into the target database
  • directly from the source database to the target database
  • from the source database onto the server running the Agent and then into the target database
  • from the source database into the machine running ODI Studio and then into the target database

Question 76

Question
You are working on notifications in a package and you must send an email containing an error message in case a Package step fails. Which odiRef method do you use to access the error message? (Choose the best answer.)
Answer
  • odiRef.getSession()
  • odiRef.getInfo()
  • odiRef.getPrevStepLog()
  • odiRef.getStep()

Question 77

Question
In a Mapping, you want to load the data by using a specific partition that is declared for a Target table. Which statement is correct in this situation? (Choose the best answer)
Answer
  • It is not possible to use a specific partition.
  • Only ODI variables can be used to filter the target table loading.
  • An option in the Mapping can be used to declare partitions but an ODI variable must be used to evaluate the correct partition value.
  • An option in the Mapping can be used to declare the partition that has to be used for the loading.

Question 78

Question
How can you define the order in which target data stores are loaded in a Mapping? (Choose the best answer.)
Answer
  • ODI automatically computes the load order based on the order on which the data stores were added to the Mapping.
  • You can use the Target Order field.
  • You can use the Target Load Order field.
  • You can use the Load Order field.

Question 79

Question
Identify two benefits that are unique to ODI JEE Agents. (Choose two.)
Answer
  • high availability
  • minimal footprint
  • access to WebLogic connection pools
  • management in Enterprise Manager Cloud Control
