Loading zolca file in olca-ipc

[zond]

Hello,

I'm interested in loading an existing zolca file into the server when running olca-ipc as an IPC server, specifically https://simapro.com/products/agribalyse-agricultural-database/.

How do I do that? I looked around in the RPC handlers, and found nothing that corresponded to the 'restore database' menu option in the app.

I tried to just unzip the zolca file in a directory, and use that directory as -db option. The server started, but I'm not yet sure if this will lead to the expected results..

I tried setting up something similar over the past few days.
For me your described process worked, I just had to make sure to build the correct version of openLCA.
My database was created using the 1.10 release, so I had to build a v1.10 IPC Server.
Here is a Dockerfile that works for me:

FROM maven:3.8-openjdk-8
RUN apt-get install git;
RUN mkdir /db
RUN git clone https://github.com/GreenDelta/olca-modules.git
WORKDIR /olca-modules/
RUN git checkout v1.10
RUN sed -i 's/.*olca-geo.*//' pom.xml
RUN mvn clean install -DskipTests
WORKDIR /olca-modules/olca-ipc
CMD mvn -P server-app exec:java -Dexec.mainClass=org.openlca.ipc.Main -Dexec.args="-db /db"

Running the image with docker run -v path/to/db:/db --name openlca-server --rm -it <image-name> should hopefully work for you too.

Ah, nice, that worked!

Some follow up questions:

• In the desktop app, I can load this same zolca-file even using version 1.4. Is there a way to do that using the headless server? I'm assuming not since it seems the headless server just assigns a database, it doesn't seem to load it per se?
• If not, is there a way to update the database, for example using the desktop app (which I would assume uses some compatibility layer to load old version databases into a new version data structure)?

Have you tried importing and exporting the database using the desktop app? I would assume that the exported .zolca file can be used with the headless server.
Regarding direct imports, the only thing I found was the -db argument, so I do not think anything else can be done here - I am certainly no expert on the software though.

Oh, I realized I am of course not using 1.4 on the desktop, since I'm using the latest release!

But thank you for the advice - I'll try that if I want to run the headless version in a different version than the desktop version :)
