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]
      service jboss.deployment.subunit."rapidminer-server-9.8.0.ear"."rapidminer-server-war.war" (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-war.war".STRUCTURE (missing) dependents: [service jboss.deployment.unit."rapidminer-server-9.8.0.ear".PARSE] 

it always stops here.
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")
server Log

I hope u can help me

    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

    Hi,

    this should be described in the documentation of your database or the JDBC driver. The setting is not coming from RapidMiner.

    The error message says that you should check the serverTimezone connection property. This would belong into standalone.xml in the configuration directory, under <connection-url>, I guess. Check the documentation that belongs to your JDBC driver for the exact syntax.

    Regards,
    Balázs
