We're seeing the warning message
2015-03-10 16:59:21,423Z (16:59) [Event Sink Thread Pool Thread 1] WARN com.itko.lisa.coordinator.TestRegistryImpl - Couldn't extract hostname of database from url: jdbc:oracle:thin:@<hostname>:1521:<hostname>
every 30 seconds in our registry log.
There are no connectivity issues with the external Oracle 11g database just wondered what it meant (apart from the obvious). The variables used in the jdbc string are for a package as we run failover on a 4 server database cluster
