    Hi khadevishal18,

    which version of RapidMiner Server are you using? The latest is currently 9.0.4.
    Just tried a headleass installation with MySQL and everything worked like expected. So, it might be nice to know which database and JDBC driver you are using. For a new installation it is also important that the database/schema does not contain any content - please make sure that it is actually empty.

    If the migration steps are still shown please let us know the version information of the migration page: configured version and the installed version.

    Cheers,
    Marcel

    We have created new database schema and privileges are also given we are doing fresh installation on Linux machine but we got the below errors?
    After first schema update we got error as "Table or view does not exists".
    We have started installing Rapidminer server on windows machine the server startup was successful.
    When we compared both logs we observed in LINUX MACHINE that Server startup is getting failed before RapidAnalytics setup is created.
    Below is log from Linux machine..
    Complete Log is also attached.

    So, both machines are using the same DB? Or have you installed the DB on the host as well? Could you please provide the DB version you are using? It might also be helpful to know the Linux distribution/version. You are using the Oracle JRE, right?
