The configuration properties of an existing persistence instance can be updated at runtime. If the persistence instance is in use at the time of a reconfiguration, then new connections will be established with the new configuration properties, and any existing connections to the database will be closed when they become idle.

To update an existing persistence instance, use the following rhino-console command or related MBean operation.

Console command: updatepersistenceinstance


updatepersistenceinstance <name> [-type type] [-ds <datasource-class-name>]
[-set-property <property-name> <property-type> <property-value)]*
[-remove-property <property-name>]*
    Update a persistence instance configuration.


$ ./rhino-console updatepersistenceinstance oracle \
    -set-property URL java.lang.String jdbc:oracle:thin:@oracle_backup:1521:db \
    -set-property user java.lang.String '${MANAGEMENT_DATABASE_USER}' \
    -set-property password java.lang.String '${MANAGEMENT_DATABASE_PASSWORD}'
