@@ -22,7 +22,7 @@ The following JVM option instructs the application to act as the dedicated timer
 
 ``-Ddataverse.timerServer=true``
 
-**IMPORTANT:** Note that this option is automatically set by the Dataverse installer script. That means that when **configuring a multi-server cluster**, it will be the responsibility of the installer to remove the option from the :fixedwidthplain:`domain.xml` of every node except the one intended to be the timer server. We also recommend that the following entry in the :fixedwidthplain:`domain.xml`: ``<ejb-timer-service timer-datasource="jdbc/VDCNetDS">`` is changed back to ``<ejb-timer-service>`` on all the non-timer server nodes. Similarly, this option is automatically set by the installer script. Changing it back to the default setting on a server that doesn't need to run the timer will prevent a potential race condition, where multiple servers try to get a lock on the timer database.

 **Note** that for the timer to work, the version of the PostgreSQL JDBC driver your instance is using must match the version of your PostgreSQL database. See the :ref:`timer-not-working` section of Troubleshooting in the Admin Guide.
