Hello there, We want to use Nexus version 3.70.1-02 with the H2 database as the default DB. However, when we try to install it, it always starts with OrientDB. We know that version 3.70.1-02 supports both databases, and we need to make some changes in the nexus.properties file. After trying severa…

For a brand new deployment (no sonatype-work directory) you will have to create the path and file: /opt/<nexus directory>/sonatype-work/nexus3/etc/nexus.properties - in this file add the line ‘nexus.datastore.enabled=true’ and then start the application. This will start Nexus with the H2 database. I…

@laurencet Thank you for your response. Apologies if I misinterpreted your explanation; please correct me if I’m wrong. Since we are using Nexus as a container, do we need to do something like this? Create the directory /opt/<nexus directory>/sonatype-work/nexus3/etc/ Add the preconfigured nexus.…

Hey Sam, Since you’re running in a container it may be easier to just pass this as an enviroment variable. Depending on your method (docker run or docker compose) you could achieve this with the following: Docker run: -e INSTALL4J_ADD_VM_PARAMS="-Dnexus.datastore.enabled" Docker compose: enviro…

Hello @laurencet I tried the suggestions you asked me to test: I added ENV INSTALL4J_ADD_VM_PARAMS=-Dnexus.datastore.enabled in the Dockerfile. I also added the same environment variable in the Compose file. (Note: I didn’t created path and preconfigured nexus.properties file you mentioned in yo…

Hey Sam, Have you deleted the ‘sonatype-work’ directory since your previous attempts? Once nexus has started once with Orient then it will default to that. That being said it looks like Nexus is still trying to use Orient. You shouldn’t need to add anything to the Dockerfile just to your compose fi…

[image] SAM: Regarding the migration guide could you clarify the actual purpose of backing up the old database? Is it a precautionary step, or is it mandatory to back up the old database before starting the DB migrator? Apologies, forgot to address this part. The task to export the DB files i…

@laurencet Yes, I am removing the old repository to start fresh. I’m not sure, maybe I’m missing something. Even after adding NEXUS_DATASTORE_ENABLED=true, in ENV it still points to OrientDB. But the interesting part is that I created this path: /opt/sonatype/sonatype-work/nexus3/etc/ and added …

Apologies, forgot to address this part. The task to export the DB files is a requirement as these are used for the migration utility. As with any activity of this type, its always recommended to take comprehensive backups (and test them)!
