Rapidminer Server 9.5 to 9.7 migration error

dvelas25

Hello Rapidminer community,

I'm having trouble with the migration of rapidminer server 9.5 to version 9.7

The error comes when I start the upgrade process and go to the part where the install location and home directory must be specified.

When I put my current home directory, it shows me the following error: Invalid home directory! Value of 'rm.server.version' or 'rmserverversion' needs to be specifed.

If I press Install it will show me a pop up with the same error.


Anyone knows what could it be?

Thanks in advance,
David

Hi @dvelas25 Are you sure that '/home/rapidminer/rapidminer-server/rapidminer-server-home' is a valid RapidMiner Server/AI Hub home directory? Normally you should have a '.rms/' folder in the RapidMiner Server home directory with a file called 'app.properties'. The upgrade process reads from this file and fails if it doesn't recognize such a file. Did you upgrade from any prior version to 9.5 or is 9.5 the first version you did install?

When you open the 'app.properties' file you see a list of properties, something similar to the following.

rm.server.radoop.enabled=false
rm.server.windows.service.enabled=false
rm.server.ja.bundled=true
rm.server.version=9.5.0
rm.server.java.use_system_java_home_or_path=true
rm.server.install.dir=/home/rapidminer/rapidminer-server/rapidminer-server-9.5.0
rm.server.java.home=java
rm.server.db.type=PostgreSQL
