When you use the DB2 Installation Wizard, the default action is to create a new user for the DB2 instance. The default name is Db2inst1. If the user name already exists, the DB2 Installation Wizard searches for the user name (Db2inst2, Db2inst3, and so on) in turn. The search continues until it identifies a user masterpiece that is not an existing user on the system as the default instance owner identity. If you choose to continue, the user will be created by the DB2 Setup Wizard. However, you can also choose to specify any existing user as the instance owner.

This method for user name creation also applies to creating protected users and DB2 Management Server users.
