Oracle Database for Windows lets you have multiple Oracle homes on a single computer.

This feature, described in Appendix B, "Optimal Flexible Architecture", in Oracle Database Installation Guide for Microsoft Windows, affects Oracle Services naming conventions. As you perform installations into Oracle home directories:

• You must accept the default Oracle home name provided or specify a different name for each Oracle home directory.

• You are prompted to give a system identifier and a global database name for each database installation.
