Why is my Rapidminer Server not running?

SaschaITPL

It ran for a while but now i needed to restart the server and i cant get my Rapidminer Server running again.

JBAS014775:    New missing/unsatisfied dependencies:
      service jboss.deployment.subunit."rapidminer-server-9.8.0.ear"."rapidminer-server-ejb.jar" (missing) dependents: [service jboss.deployment.unit."rapidminer-server-9.8.0.ear".PARSE]
      service jboss.deployment.subunit."rapidminer-server-9.8.0.ear"."rapidminer-server-ejb.jar".STRUCTURE (missing) dependents: [service jboss.deployment.unit."rapidminer-server-9.8.0.ear".PARSE]

it always stops here.

I had the problem discussed here:
https://community.rapidminer.com/discussion/50368/rapidminer-server-not-starting-up-any-more

and the old Error disapears, but now i get the new one.

(old Error was: JBAS014777:   Services which failed to start:      service jboss.persistenceunit."rapidminer-server-9.8.0.ear/rapidminer-server-ejb.jar#RapidRepositoryEntity")

Hi,

this looks fishy:
2021-02-24 10:30:53,147 WARN  [org.jboss.jca.core.connectionmanager.pool.strategy.OnePool] (JCA PoolFiller) IJ000610: Unable to fill pool: javax.resource.ResourceException: Could not create connection
...
Caused by: java.sql.SQLException: The server time zone value 'Mitteleurop�ische Zeit' is unrecognized or represents more than one time zone. You must configure either the server or JDBC driver (via the 'serverTimezone' configuration property) to use a more specific time zone value if you want to utilize time zone support.

It seems that the system can't connect to the database because of a wrong timezone name. You might be able to reconfigure the database server or the connection, e. g. to UTC. 

Best regards,

Balázs
