According to the documentation for installing Oracle JDBC drivers, I just downloaded the driver ojdbc6.jar copied into $SPLUNK_HOME/etc/apps/dbx/bin/lib and then restarted Splunk.
In Database connections in Splunk Manager I choose under Database Type: Oracle and got this error message:
ERROR com.splunk.dbx.DbxException: Database type Oracle does not implement catalog enumeration
Whats wrong? Was ist los?
