DB2 Version 9.7 for Linux, UNIX, and Windows

Oracle-compatible mode can be enabled

To make the DB2® environment more compatible with the Oracle database management system environment, you can set the new DB2_COMPATIBILITY_VECTOR registry variable.

This registry variable is represented as a hexadecimal value, and each bit in the variable enables one of the DB2 compatibility features. Depending on the application that you want to enable for the DB2 data server, you can turn on compatibility for data types, semantics, and behaviors that the application might require.
