"Problem with Oracle driver on non-standard port?"

edited May 2019 in Help
RapidMiner 5.0.0.11 on windows XP.

As per instructions, I have identified the Oracle connector and path in my local
%userprofile%\.RapidMinder5\jdbc_properties.xml, and everything looks OK. 

One non-standard feature:  We operate our Oracle servers on a custom port.

I have several other apps that use jdbc (Talend, JasperSoft), and the connection URL looks good in RapidMiner.  However, I get "Io exception: The Network Adapter could not establish the connection"  when I attempt to connect.

any ideas?

    Hi,
    what does the "Test" Button in the Manage Database Connections Dialog say?

    Yes, the error indicated occurs when I push the Test button, while defining/editing the connection.

    Hi,
    well actually I doubt this is a problem of RapidMiner. As the error indicates it seems to be located in your network settings. Might be you blocked outgoing connections from java / RapidMiner in your firewall?
    Connecting to non default ports works for me at least with MySQL...

    I guess I don't have to mention that we could invest more time helping you if you would have signed a support contract :)

    I don't see how it would be a network/firewall/client problem external to RM.

    I regularly use two other (java) applications, connecting to the same Oracle instance(s), with the same Oracle jdbc driver, from the same workstation/system.  Those apps are (1) JasperSoft's iReport (3.6.0 and the latest 3.7.x, community and Pro);  and (2) Talend's Open Studio (ver4.1) for ETL.

    I also tested with MySQL, works fine.

    OK, FIXED, category is "not exactly a problem." 

    The problem is in the way RM handles ORA-28002 "errors"  and ORA-28011.  These error messages look like this:

    ORA-28002: the password will expire within %n days
    ORA-28011: The account will expire soon; change your password now


    The message appears just after a client logs in.  In our shop, these notices start coming up 2 weeks before the password must be changed.  It was a coincidence that I needed to do some analysis during this period.

    The Manage Database Connections task generates an error when this is detected.
