Care needs to be taken when working with time zones. Mixing time zones can lead to great confusion. It is wise to define the time zone as an offset with respect to UTC and use this throughout. In configuring import data, a local time zone can be used. It is advisable to always set time zones when required. |
vjdbcServicePortRange
The FEWS Stand Alone can start an embedded VJDBC server automatically or through the debug mode.
Starting VJDBC server automatically:
When the Explorer.xml file of the Stand Alone system contains an additional element “vjdbcServicePortRange”, the Delft-FEWS internal vjdbc server will start automatically when the Stand alone is started. For the port number a range of the port numbers can be provided., for example <vjdbcServicePortRange start="2000" end="2005"/>
We advice to use the portrange starting from 2000.
Starting VJDBC server through the debug mode :
When there is no prto range configured the embedded “vjdbcServicePortRange” configured, you can start VJDBC server with Explorer F12 menu option “M start embedded vjdbc server”. Then the embedded VJDBC Server will use port number 2000.
This VJDBC functionality can be used to analyse the database of the Stand Alone using external tools like DBVisualizer. Or it can be used to start a FEWS Stand Alone in participant mode or the Water Coach in participant mode (Application configuration)
