You can consult the query info output (which you find in the [[GUI#Visualizations|Info View]] of the GUI or which you can turn on by setting <code>[[Options#QUERYINFO|QUERYINFO]]</code> to {{Code|true}}) to find out which databases have been locked by a query.
==Process Locking==
In order to enable locking on global (process) level, the option <code>[[Options#GLOBALLOCK|GLOBALLOCK]]</code> can be set to {{Code|true}}. This can e.g. be done by editing your {{Code|.basex}} file (see [[Options]] for more details). If process locking is active, a process that performs write operations will queue all other operations.
