Defining Coverage

1. Subscription Services seeks to ensure that the product can connect to and use a compatible database to store and retrieve data.

2. Liferay seeks to resolve any issues with the product when connecting to each compatible database. Issues with the database application itself must be handled by that database's vendor.

3. Subscription Services will provide guidance on connecting the product to a compatible database that the product can use to store Liferay data.

4. Liferay isn't responsible for data loss or corruption that results from manually manipulating the database's content, or improperly implementing customizations.

Compatible Versions

1. Liferay software is compatible with all minor/patch versions of the major database versions listed in the Compatibility Matrix.
2. Liferay only assures compatibility with database versions that are actively supported by a third-party vendor.
   1. Liferay does not assure compatibility with any beta versions of a database application.
   2. Once a database version reaches the end of its lifecycle, support is provided on a case-by-case basis.

Compatible Features

1. Liferay assures compatibility with a database's native features as long as the logical structure of the product-created tables isn't modified.

2. Liferay does not test compatibility with clustered database applications. As long as the the tables' logical structures aren't modified, and the replication is a native feature of the database application, the Liferay product should function without issue. If any issues related to a clustered database are reported, those issues will only be tested and verified in a single-node database environment.

3. The product requires a UTF-8 character set for all features to operate correctly.

SQL Scripts

SQL scripts are available in the Downloads section of Help Center as part of the product source files. These scripts are designed for database administrators (DBAs) to create a product database while maintaining restricted application permissions. Certain product features (like deploying a new plugin) may require extended permissions and may be unavailable if database permissions are overly restrictive. The use of these scripts in any particular environment is at the customer's discretion.

Specific Database Applications

Some of the compatible database applications have specific policies associated with them and some features or settings may be incompatible with the product. For more details, please review the support coverage of each compatible database application. Database applications found on the Compatibility Matrix, but not listed below, do not have specific policies associated with them.

• MySQL
• Oracle Database
