Right-click the step in Package Editor and select the No Logging menu item.

Modify Operator Navigator settings to disable that step from being displayed.

In Package Editor, click the step, go to the Advanced tab, and set Log Steps in the journal to Never.

Periodically schedule a scenario that usesOdiPurgeLogto remove that step from the ODI logs.

Restart from new session.

Restart from failure.

Restart from failed children.

Restart all children.

ODI uses its own transformation engine to process data in a Hadoop cluster.

ODI performs data transformations inside a Hadoop cluster.

ODI must perform data transformations outside Hadoop in an Oracle database.

ODI allows moving data in and out of a Hadoop cluster.

You must consolidate your own local metadata repositories. The local metadata must be transmitted via ftp and synchronized with a dedicated proprietary engine, creating a common metadata model for all the developers.

You must consolidate your own local metadata repositories. You have to invoke a dedicated web service to synchronize the metadata by using Oracle Service Bus.

You need not consolidate your own local metadata repositories, because the ODI proprietary metadata server allows all developers to share the common metadata of a specific project.

You need not consolidate yourown local metadata repositories, because ODI uses a centralized relational metadata repository that all the developers share.

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 can add a primary key even if it does not physically exist on the related database catalog, by adding constraints to the data store diagram.

You cannot add a primary key if it does not physically exist on the related database catalog. You can flag only non-null conditions to be checked.

You cannot add a primary key if it does not physically exist on therelated database catalog. You can reverse engineer only the existing constraints.

Data transformation must be distributed across several scalable nodes.

It is mandatory to have an intermediate server.

It is better to load data directly from sources into a data warehouse server.

It is mandatory to collect data directly from sources to a data warehouse server by using real time replication processes.

The Knowledge Module must be customized because business rules and the physical implementation are strictly interlayed in ODI.

The Knowledge Module must be customized only for aggregation functions.

The Knowledge Module need not be customized because aggregation code is generated automatically by ODI according to the Mapping logic.

The Knowledge Module need not be customized, but a variable must be used in the aggregate expression to generate the correct sum.
