# 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](https://adoptopenjdk.net/?variant=openjdk11&jvmVariant=hotspot)
|
|
* 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](https://repo1.maven.org/maven2/org/opentripplanner/otp/2.0.0/).
|
|
You find more details in the [Basic Tutorial](http://docs.opentripplanner.org/en/latest/Basic-Tutorial/)
|
|
Copy JAR archive from Maven [directory](https://repo1.maven.org/maven2/org/opentripplanner/otp/2.0.0/) 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](https://github.com/Stefan-Begerad/otp-setup) 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](http://docs.opentripplanner.org/en/latest/Basic-Tutorial/)
|
|
* Download GTFS [data](vbn.gtfs.zip) from Connect-Fahrplanauskunft GmbH
|
|
* Download osm map data from [geofabrik](lower-saxony.osm.pbf.ln)
|
|
* 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](vbn.osm.pbf)
|
|
* `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 .

### 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.
|
|
|
|
```
