4.3 Oracle Database XE User Data Limitations

The maximum amount of user data in an Oracle Database XE database cannot exceed 12 gigabytes. If the user data grows beyond this limit, then an ORA-12592 error will appear. To use more than 12 gigabytes of user data, upgrade to Oracle Database 18c Personal Edition, Oracle Database 18c Standard Edition 2, or Oracle Database 18c Enterprise Edition.
