Ocean/ConfigurationDB/Init.go
Thorsten Sommer a007db1b79 Bug fixes and improvements
+ Add a function to the Tools package to provide the local IP address
and port
+ Add a function to the Tools package to provide a time as formated
string as yyyyMMdd hhmmss.fff
+ Improved the ICCC startup message: Now, the message contains the IP
address and port of the stared server
+ Add a new configuration to specific the necessary Ocean servers' port
(internally, not the public port)
+ The template package reports now which version out of the grid FS is
used.
+ The Ocean server is now bound to the correct IP address and port
(rule: the local IP address!)
+ The order of the system shutdown handlers were wrong!
+ The early ICCC messages problem is now fixed!
+ Fixed an ICCC bug for the case, that a message does not have any
payload!
+ Also the configuration database uses now the correct mgo MongoDB rules
(SetSafe & SetMode)
