I'm trying to setup eclipse to work with JDBC. I have installed the Oracle express database, and started it. Connecting to the database through the SQL command line works.
When I try to setup the connection in eclipse, and I press "Test Connection", I get a "Ping failed" error message. I think I'm using the correct JDBC version (11.2.0.2, version number found from SQL command line window), downloaded from here. The service name is set to xe and the host is set to localhost, port to 1521. The username and password are the same that I use in the SQL command line.
Any idea what the problem is? I'm on Linux, if relevant.

The Goal
I need to get data from a MongoDB updated every 15 minutes to use to build into a PowerBI report.
The Gear
I am connected from my windows machine via ssh to an RHEL server (server a). This server is running powerbi connector (SQLD) which is connected to my MongoDB that is running on a different server (server b). I'm also running MySQL on server b. My powerBI connector is installed on server b.
Exactly where I'm at
I am using the steps listed here (and all the associated pages) and have tried everything listed short of writing a config file, as the fact that things are working on mongosqld's end makes me think I don't need it... and if I can't get it working manually, having a config file won't exactly help.
https://docs.mongodb.com/bi-connector/current/connect/powerbi/
Using:
mongosqld --mongo-uri="mongodb://10.xxx.xxx.xx" --auth --mongo-username="ThisGuy" --mongo-password="test"
I successfully map the schema and show an active connection in the command window. I can also access my database from compass using an authorization enabled URL.
When I set up an ODBC connector I use the IP of server a, the user and password from my url, and port 3307. Nothing shows up in the dropdown, when I click 'test' I get the following message:
Connection Failed
[MongoDB][ODBC 1.4(w) Driver]Can't connect to MySQL server4 on '10.xxx.xxx.xxx' (10060)
I have also tried 3306, 27017, and 27015. Just to be safe I also added firewall rules for all traffic on these ports. I've tried this many times, including (just for the hell of it, and I'm kind of new to this stuff) the ip of server b, the ip of my machine, the credentials for MySQL, basically any combination of these things that I can think of.
In powerBI, my odbc driver shows up, and when selected in the dropdown, it asks for a username and password. I have tried both mongo credentials and MySQL. Not sure which I should be using?
regardless, I get the following error inside PowerBI:
Details: "ODBC: ERROR [HY000] [MySQL][ODBC 1.4(w) Driver]Can't connect to MySQL server on '10.xxx.xxx.xxx' (10061)
ERROR [HY000] [MySQL][ODBC 1.4(w) Driver]Can't connect to MySQL server on '10.xxx.xxx.xxx' (10061)"
Thoughts
I don't control either server, although I have root access, being new to this tech and company I am wary of screwing anything up that a co-worker will have to fix. I read in a different SO thread that maybe I need to downgrade the version of MySQL that is running on the server and that it could fix the problem, but I don't think that it will actually help and am afraid I might screw up something else on the server if I do this:
The C Authentication plugin was developed against MySQL 5.7.18 Community Edition (64-bit), and tested with MySQL 5.7.18 Community Edition and the latest version of MongoDB Connector for BI. The plugin is not compatible with MySQL Server or Connector/ODBC driver version 8 and later.
https://dba.stackexchange.com/questions/219550/access-denied-when-connecting-to-mongosqld-with-mysql
Maybe the problem is that server B is listening to server a on port 3307, and that there is another unknown port (not mentioned above) that my ODBC driver must be listening to? I'm not sure how to test for this when you get a step away like this.
So that's it. I'm really stuck and would love some help, I am going to try the downgrade tomorrow if nothing else shakes loose and will keep this thread updated.
Thank you for reading
I'm on a Windows server and I have installed 2 things:
- MariaDB version 10.5.9
- MariaDB ODBC Driver version 3.1.13
Now I'm using the ODBC Data Source Administrator to create an ODBC connection. So I clicked on 'Add', chose MariaDB ODBC driver and got the following screen in front of me:
I really have no clue what to fill under Server Name, Port, User Name and Password. Especially the Server name seems quiet hard because I don't know where to get it from....
Can you guide me about the connection between mongodb and power bi through ODBC driver. I have connection between them. but i got unexpected errors like:
"OLE DB or ODBC error: Exception from HRESULT: 0x80040E4E." , "OLE DB
or ODBC error: [DataSource.Error] ODBC: ERROR [42S22] [MySQL][ODBC
1.4(w) Driver][mysqld-5.7.12 mongosqld v2.14.3]Unknown column 'COD' in 'field list'."
and
"DataSource.Error: ODBC: ERROR [08S01] [MYSQL][ODBC 5.3(w) Driver Lost
conection to MySQL server at 'waiting for initial communication
packet', system error: 10060".
Can you tell me where the problem and how can I overcome on it?
I've had the same problem, try to go over the below steps and take a look at my advice under the fourth point (4).
Install mongosqld on your server based on your OS (first prerequisites).
LunchBI connector:
a) Make logs folder and mongosqld.log file in it.
b) Setup mongosqld.conf (IP:<your_server_ip>, PORT:3307)
Install mongosqld as a System Service link
Create a system DSN on your computer based on your OS, link.
Hint: On Windows (in ODBC data source) try to make both ANSI and UNICODE
connectors and do not forget to select a database in the dropdown menu.*
e.g. connect to Mongo via PowerBI via ODBC
a) Select a connector
b) Select the database, that you have selected in the previous dropdown menu.
For more information follow the official guide
you have to install mongosqld on your server and configure the .yalm file.
Inside it you have to uptade 'bind ip' field, by adding the remote ip.
I am trying to connect my Oracle Database 10g Express Edition with sql*plus. when i start the sql*plus command window the following error occurs.
could you please show me the way of avoiding this error.
As per the 2nd result from a Google search on the error message:
Typically this will result from
not having ORACLE_SID properly set. Especially so on Windows.
not having the db service started. See the windows services applet, services.msc

I'm using Eclipse Juno with the SQL Explorer plugin. I've set up an SSH tunnel for port 3306 via Putty to my production server and have successfully connected to that server's MySql instance. I can view the database's schema as well as getting a preview of a table's data. When I try to execute a basic SELECT query, without a database qualifier on the table, Eclipse gives me a NullPointerException with no additional information. However, if I include the database qualifier, it works.
The database selector in Eclipse/SQL Explorer is set correctly and everything works as expected if I'm not running over the SSH tunnel (e.g. locally or a direct remote connection).
Is there something that I'm overlooking?
The problem was caused by a bug in the SQL Explorer plugin (see http://sourceforge.net/p/eclipsesql/discussion/450662/thread/f1e73461). The symptom was a red herring. The NPE would occur when the plugin tried to write to its history file. Clearing the history file resolved the problem.
