Launching Delft-FEWS 2017.01
to be inserted!!!!
...
A typical FEWS installation has the following subdirectories in the FEWS root directory:
- bin: The FEWS binaries, scripts and native code.
- jre: The java runtime
- RegionHome: The region home with the FEWS configuration
Windows 32 and 64
Since 2017.01 FEWS is launched from the RegionHome directory. In the bin/launcher directory there are startup scripts available for all supported platforms (windows32, windows64, linux). Depending on a 64 or 32 bit environment copy the appropriate scripts to the RegionHome, for example Delft-FEWS_x64.ini and Delft-FEWS_x64.exe. Running Delft-FEWS_x64.exe will launch FEWS. The .exe can be renamed. This is convenient when having multiple FEWS system so you see the difference in the Windows Task Manager. The .ini file should always have same name as the .exe.
Linux
On linux the fews.sh script can be copied from the bin/launcher/linux directory to the FEWS root directory. Make sure the fews.sh script has executable permissions set. To run FEWS from the root directory run: ./fews.sh RegionHome. The fews.sh script also specifies the java heap size that is used by FEWS. To increase the size, this script should be tuned.
