I read through the installation manual for Oracle Applications 11iR3 and have made several attempts to install it on NT4. However, I notice the only user account RapidWizard prompts me was the NT account for Concurrent Processing server, which is usually the "applmgr" account. This make me wonder: do we have to have two accounts, one for Oracle DB and the other for Applications on NT? I know on UNIX, it is optional to have two accounts. If I only need one, after the install, which environment setup file should I run? APPSORA.CMD or .CMD in ORACLE_HOME?
