The data movement mode is a PowerCenter Integration Service option you choose based on the type of data you want to move, single-byte or multibyte data. The data movement mode you select depends the following factors:
Requirements to store single-byte or multibyte metadata in the PowerCenter repository
Requirements to access source data containing single-byte or multibyte character data
Future needs for single-byte and multibyte data
The data movement mode affects how the PowerCenter Integration Service enforces session code page relationships and code page validation. It can also affect performance. Applications can process single-byte characters faster than multibyte characters.
