Breaking: #75454 - LocalConfiguration DB config structure has changed ¶
See Issue #75454
To provide support for multiple database connections and remapping tables to different
database systems within the TYPO3 Core the configuration format for database connections
The new configuration array structure:
'DB' => [ 'Connections' => [ 'Default' => [ 'driver' => 'mysqli', 'dbname' => 'typo3_database', 'password' => 'typo3', 'host' => '127.0.0.1', 'port' => 3306, 'user' => 'typo3', 'unix_socket' => '', 'charset' => 'utf-8', ], ], ],
Be aware that besides the deeper nesting below ‘Connections/Default’ some of the configuration
keys have been renamed. It is required to provide the new configuration key
The following table lists the changed configuration keys and the appropriate values if these have changed.
|Old name||New name|
|SYS/dbClientCompress||DB/Connections/Default/driverOptions Valid values for MySQLi connections: 0 compression disabled 32 compression enabled|
Connections to the database will fail with an exception until the configuration has been migrated to the new structure.
Affected Installations ¶
The Install Tool will migrate the configuration information for the default connection to the new
format. Installations overriding the database configuration using
or other means need to ensure the new format is being used.
