Moving Data

Question

You want to distribute a set of structured data to your customers who can integrate this data into their existing databases irrespective of the platform. Which method provides the fastest way of achieving this?

Options

Ausing the DBVERIFY utility
Busing direct-path INSERT SQL statements
Cusing SQL*Loader
Dusing RMAN transportable tablespace operation

Explanation

To quickly integrate structured data into an Oracle database, direct-path INSERT SQL statements offer the fastest method by bypassing the buffer cache and writing data directly to data files.

Common mistakes.

A. The DBVERIFY utility is used for checking the integrity of Oracle data files and is not a mechanism for data distribution or loading.
C. SQL*Loader is a utility for bulk loading data from external files into Oracle tables, and while it can use direct path mode, the question specifically refers to direct-path INSERT SQL statements.
D. An RMAN transportable tablespace operation is used to move an entire tablespace between Oracle databases and is not a platform-agnostic method for general data distribution.
