Change Default EnterpriseOne System User Passwords for the Database
The EnterpriseOne installation process creates various database users with a default password ("Same as User"). When setting up sign-in security for EnterpriseOne users, each user sign-in record must be associated with a database user, also referred to as a system user, to access the database.
You should change these database user passwords after a successful installation or upgrade. After changing a database user's password, you might have to modify configuration files for the Deployment Server and EnterpriseOne Security Server (also known as the Enterprise Server) because these servers use information from the configuration files to connect to the database. See Default Database User Accounts in this guide for a list of default database user accounts for JD Edwards EnterpriseOne 9.1.
To use the long DB proxy password during an upgrade and ESU installation, you must have the Security Server on and you must add security overrides for all the data sources related to the upgrade or ESU target environment (Tools Release 9.2.5).
The long DB proxy password is not supported during the Installation Workbench. You can only turn on the password after completing the first Installation Workbench, as you need have the Security Server running.
For instructions on how to update the passwords in the configuration file settings on the Deployment Server and Enterprise Server, see "Working with Database Security" in the JD Edwards EnterpriseOne Applications Installation or Upgrade guide for your platform and database:
