    @narasimhado you know if MySQL is being used as the backend DB for running Server? IF so, you need to change the maximum packet size. It's usually too small by default.

    @Thomas_Ott: Hi, Thank you for reply

    But we are using "Amazon Redshift" as backend Data base

    @narasimhaoh ok, does Studio have the right security group permission enabled then? Do you have support with RapidMiner, if yes, I'd ask them. I'm only now learning how to leverage AWS and RapidMiner so I'm afraid I'm a n00b

    Hi@narasimha,

    I am not sure if Amazon Redshift is fully compatible for a RM Server backend. RM Server needs a traditional transactional database for storing its data, as it uses optimizations that may not be available in a cloud DW.

    In the case of AWS, I think that Amazon Aurora might be able to pull it off, as it is MySQL and Postgres compatible.

    Edit: or Amazon RDS

    yes I would recommend starting with AWS RDS as your Server backend (I usually use MySQL for simplicity). Works very nicely. And yes@Thomas_Ottthe trick is the IAM permissions. Best practice would be to create a VPC and let the server talk to the database behind this. This way your database is not exposed.

    @sgenzer,@SGolbert: Thank you for the reply

    Now the backend Database is "MySQL", even though same error with "Store" Operator.

    Below is the error message :

    不能保存库数据
    Cannot store data in the repository at entry '../data/Averages'. Reason: Cannot upload object: 500: Internal Server Error

    pretty sure that's still an IAM issue
