Creating a new database in Oracle 18c XE throws this error, does this mean that I can only use the database created by the installation?

ORA-00442: Oracle Database Express Edition (XE) single instance violation error

ORA-00600: internal error code, arguments: [OSDEP_INTERNAL], [], [], [], [], [], [], [], [], [], [], []

ORA-27302: failure occurred at: sxesingleins ORA-27303: additional information: environment variable ORACLE_SID should be XE only

  • In Oracle you rarely need additional instances (=database). You typically just create a new schema/user – a_horse_with_no_name Mar 9 at 18:47

Licensing Restrictions

Oracle Database XE restricts itself to only one installation per logical environment. The logical environment can either be a virtual host such as a VM or container, or a physical host. If more than one Oracle Database XE installation is attempted to be started in such a logical environment, an "ORA-00442: Oracle Database Express Edition (XE) single instance violation error" is raised and the database will not start.
