4.1.1 About the RQSYS Schema

The RQSYS schema is the system account for Oracle Machine Learning for R in Oracle Database.

It contains metadata, PL/SQL packages, and other executable code that is used internally by OML4R Server.

The OML4R Server installation process creates RQSYS as a locked account with an expired password. The rqsys user does not have the CREATE SESSION privilege.
