The Artemis server that are integrated to WildFly can be configured to use a JDBC store for its messaging journal instead of its file-based journal.
The server resource of the messaging-activemq subsystem needs to configure its journal-datasource attribute to be able to use JDBC store. If this attribute is not defined, the regular file-base journal will be used for the Artemis server.
This attribute value must correspond to a data source defined in the datasource subsystem.

For example, if the datasources subsystem defines an ExampleDS data source at /subsystem=datasources/data-source=ExampleDS, the Artemis server can use it for its JDBC store with the operation:

/subsystem=messaging-activemq/server=default:write-attribute(name=journal-datasource, value=ExampleDS)

Artemis JDBC store uses SQL commands to create the tables used to persist its information.
These SQL commands may differ depending on the type of database. The SQL commands used by the JDBC store are located in the file at:

$JBOSS_HOME/modules/system/layers/base/org/wildfly/extension/messaging-activemq/main/database/journal-sql.properties

By default, "vanilla" SQL commands are used to communicate with the database. However some databases requires specific commands to create table, update content, etc.

The journal-sql.properties can also specify these provider-specific commands. You can customize them by adding a suffix to the vanilla SQL properties.

The suffix is determined based on information from the JDBC driver and the connection metadata. If the type of database is not supported by the code, you can specify it explicitly with the journal-database property on the server resource.

Artemis uses different JDBC tables to store its bindings information, the persistent messages and the large messages (paging is not supported yet).

The name of these tables can be configured with the journal-bindings-table, journal-messages-table, journal-page-store-table, and journal-large-messages-table.
