The 2.2.2 Patch for Taverna Workbench is now available to download.

You only need to install this patch if you use a mySQL database to store Taverna’s data or provenance information.

The patch alters the way that Taverna stores data and provenance information in a mySQL database. It is not compatible with the earlier mySQL provenance databases.

To install the patch:

1. Start Taverna 2.2. It is best to install the patch when no workflows are being edited or run.
2. Click “Advanced” on the top menu and select “Updates and plugins”; the Updates and plugins dialog will appear.
3. Click “Find updates” within the dialog. You should now see that updates are available for “Provenance”.
4. Select “Provenance” and then click the “Update” button on the right hand side. The Taverna user interface may be unresponsive while the update is downloaded. Do not quit Taverna. When the update has finished, Taverna will show a dialog warning that the update will not take effect until Taverna is restarted.
5. Quit Taverna
6. If you want to use mySQL,
   1. configure Taverna for the Taverna Workbench or Command Line Tool
   2. if you were using mySQL before, then drop database T2Provenance;
   3. create database T2Provenance; Do not pre-load the T2Provenance database with any tables. The tables will be created by Taverna.
   4. grant access to the mySQL database for the configured user
7. Restart Taverna.

Note that the title bar will still say Taverna 2.2.0.
