Difficulties attempting to test with NuoDB

[bryanosborne]

How well supported is NuoDB? Would like to use oltpbench for NewSQL research to be published.

Receiving runtime error:

Is there a config.xml parameter to specify the NuoDB schema? (I thought NuoDB was supposed to just create unspecified-schema objects in the USER schema, but...)

Also, I can't find any detail info on the config.xml file.

Any assistance is greatly appreciated!

"Fixed" the code with a modification to BenchmarkModule.java. Works for MySQL and NuoDB,haven't tried with other DBMS. Hope this helps.

public final Connection makeConnection() throws SQLException {
    Properties properties = new Properties();
    properties.put("user", workConf.getDBUsername());
    properties.put("password", workConf.getDBPassword());
    if(workConf.getDBName() != null) properties.put("schema", workConf.getDBName());

    Connection conn = DriverManager.getConnection(workConf.getDBConnection(),properties);
    Catalog.setSeparator(conn);
    return (conn);
}

Will do, Dr. P.
