The OrionAlarmService checks the SQL server database prepareSQL property at startup. This check may generate this error.
If it is not present, the default value for the database’s prepareSQL property (extraConnectionProperties) is 3. Setting this property to 1 may result in increased performance. However, setting this property to 1 when using the jTDS driver may cause this warning. The extraConnectionProperties values are defined here: http://jtds.sourceforge.net/faq.html. If you happen to see different results in performance, you can safely ignore the error message.
