Problem connecting Rapid Miner 5 to maxdb

Hello,

I have got a problem when trying to read data from a maxdb-database (former sapdb).

I've added a new database driver inside Rapid Miner (Tools -> Manage Database drivers) and used the operator "Read Databases". The URL to the database is:

jdbc:sapdb://<dbserver>:7210/<dbinstance>

Unfortunately I get an error when running the process:

"Cannot create example set meta data: Database error occurred: [getTypeInfo][-4004] (at 798): Unknown table name:SYSODBCTYPES."

I tested the connection with another database-program (Squirrel SQL client) with the same url, user and password, which works fine; So I'm assuming that the database-driver itself is not the problem.


Any help on this?

Thank you

    Hi,
    if you click on the test connection button in the manage Connections dialog, does the green ok icon show up?

    Hi Sebastian,

    the connection test also throws an error "[getTypeInfo][-4004] (at 798): Unknown table name:SYSODBCTYPES" (no green light)

    Hi,
    that's a little bit difficult to debug for me without having the MaxDB. You already googled for that error? It's definitivly thrown by the driver and not by RapidMiner, so I cannot say too much to this issue without having it here.

    Greetings,
