You can create a new Oracle user in the Smart Materials database. In SQL*Plus, you can log in with administrator privileges and use the following syntax:
create user SmartPlant Instrumentation identified by Smart Instrumentation;
This will create a new user called "Smart Instrumentation", but you can use another name. Give the user rights to connect to the database and the ability to have his own database objects using the following syntax:
grant connect,resource to SmartPlant Instrumentation;
