Manage Reference Index¶

The reference index in TYPO3 is the table sys_refindex. (Related link: Soft references). The table contains all relations/cross correlations between datasets. For example a content element has an image and a link. These two references can be found in this table stored against this unique data record (tt_content uid).

When you want to perform a TYPO3 update it is recommended to update these relations. See Update Reference Index.

To perform an update you can use the TYPO3 Console command shown here With command line (recommended).

TYPO3 installations with a small number of records this module can be used to check or update the reference index.

On TYPO3 installations with a large number of records and many relations between those the maximum run time of PHP will be reached and the scripts therefore fail. It is recommended to run the commands from the command line. This module outputs the commands with absolute paths to update or check the reference from the command line.
