OTP setup for VBN

There is not just one way to do it. That is why you have the following selection.

Prepare host system

Set up Java
Download JRE
Copy JRE onto host system like this:
scp -P 22 ~/OpenJDK11U-jre_x64_linux_hotspot_11.0.12_7.tar.gz sib@83.223.94.182:/home/sib/
Move and extract archive like this:
sudo mv ~/OpenJDK11U-jre_x64_linux_hotspot_11.0.12_7.tar.gz /opt/
sudo tar -xzf OpenJDK11U-jre_x64_linux_hotspot_11.0.12_7.tar.gz
Add JAVA_HOME to ~/.bashrc like this:
export JAVA_HOME=/opt/jdk-11.0.12+7-jre
Extend PATH in ~/.bashrc like this:
export PATH=$PATH:$JAVA_HOME/bin
Test JAVA version like this:
java -version

Upload OTP onto host system

Donload JAR archive. You find more details in the Basic Tutorial Copy JAR archive from Maven directory onto host file system like this.

scp -P 22  ~/otp/otp-2.0.0-shaded.jar sib@83.223.94.182:/home/sib/otp/

Copy config files from git repo onto host file system like this.

scp -P 22  otp-setup/vbn/build-config.json sib@83.223.94.182:/home/sib/vbn/otp/
scp -P 22  otp-setup/vbn/otp-config.json sib@83.223.94.182:/home/sib/vbn/otp/
scp -P 22  otp-setup/vbn/router-config.json sib@83.223.94.182:/home/sib/vbn/otp/

Validation

Print OTP version like this.

java -jar otp.jar --version|tee version.txt

Setup according to basic tutorial

Download GTFS data from Connect-Fahrplanauskunft GmbH
Download osm map data from geofabrik
Get bounding box for VBN from https://boundingbox.klokantech.com/
csv:7.6966,52.4508,9.6501,53.8503
Extract VBN map data using the tool osmconvert creating the file
cd ~/vbn/otp/
osmconvert lower-saxony.osm.pbf.ln -b=7.6966,52.4508,9.6501,53.8503 --complete-ways -o=vbn.osm.pbf
The output file is called vbn.osm.pbf
Build a street graph with OSM and elevation data only (ignoring transit input files)
java -Xmx5G -jar otp.jar --buildStreet .
The output file is called streetGraph.obj
Build a graph layering transit data on top of the saved street graph (built using the previous command)
java -Xmx5G -jar otp.jar --loadStreet --save .
The output file is called graph.obj
Copy config files to the right place like this:
tbd
Finally, the server can be started using the --load parameter
java -Xmx5G -jar otp.jar --load .

Setup accoriding to cookbook

There is a dedicated [repository[(https://github.com/transportkollektiv/digitransit-setup) for this cookbook.

Lessons Learned

Setting both MEMORY and GRAPH_BUILD_MEMORY to 4 GB and running the instruction docker-compose --env-file=.env.vbn up --build -d on a computer with 8 GB total and 4 GB memory available results in the following error.
