Oracle AI Database Free limits itself automatically to two cores for processing. For example, on a computer with 2 dual-core CPUs (four cores), if a large number of database clients try to simultaneously run CPU-intensive queries, then Oracle AI Database Free will process the queries at the rate of just two cores even if more CPU capacity is available.

To take advantage of the full processing power of your computer, you can use a different Oracle AI Database edition such as Oracle AI Database 26ai Enterprise Edition.

Oracle AI Database Free 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 you attempt to start more than one Oracle AI Database Free installation in such a logical environment, then an ORA-00442: Oracle Database Free single instance violation error is displayed and your database will not start.

This does not affect any existing installation or new installation of Oracle AI Database 26ai Enterprise Edition. To run more than one Oracle AI Database instance or install more than one copy of the database software, upgrade to Oracle AI Database 26ai Enterprise Edition.

The maximum amount of user data in Oracle AI Database Free cannot exceed 12 GB. If the user data grows beyond this limit, then the system displays an ORA-12954 error. To use more than 12 GB of user data, upgrade to Oracle AI Database 26ai Enterprise Edition.

The maximum amount of RAM for Oracle AI Database Free cannot exceed 2 GB, even if more is available.

To use more than 2 GB of RAM, upgrade to Oracle AI Database 26ai Enterprise Edition.
