I currently have a Macro which is connecting to a sybase database using ODBC. It's making the connection by running the following:
Set conX = wrkODBC.OpenConnection("Connection1", , True, strConn)
where strConn = "ODBC;DSN=Server_Name;APP=Daily Task;DB=db_name;UID=uname;PWD=pwd;"
The problem I am having is that this connection is working for some Server_Name's but not others. When it doesn't work I get a Error "3146 - ODBC--call failed".
What I don't understand is where it is pulling the server details from. So for example, when using embarcadero rapid to connect to a sybase database, it will use the sql.ini file to pull the server connection details based on the server_name.
I have checked and all the Sybase Servers I am testing are in the sql.ini file and my env variables are pointing to the correct sybase version. I've checked ODBC and it is only picking up a SQL Server driver.
Can anyone please explain how ODBC pulls the server name connection details? I don't understand why it works for some server names, but not others (FYI, I have tested the uname and pwd is rapid to make sure it is correct).
Any information would be much appreciated.
So, the issue was that I was looking at my odbc connections under control panel. I should mention that I am on windows 7. What I had to do was update my ODBC connection details here:
C:/Windows/SYSWOW64/odbcad32.exe
--This is for 32bit!
This had some connections set up which is why I could connect to some servers but not all of them.

Objective: Set up a connection with PostgreSQL db in PDI. I'm a noob in all this stuff, so each step forward requires long resolution time.
I'm trying to set up the connection to a PostgreSQL database in order to prepare some queries for an ETL process in PDI. But there's no way to succeed with the connection.
I've tried with PostgreSQL connection type and with Generic database connection type and the error is always related with the drivers.
The version of the PostgreSQL db I'm trying to connect is 9.5.25 and I'm working in Ubuntu 20.04 and Java 8 as demands Pentaho Data Integration.
Below the error message after failed connection:
"Connection failed. Verify all connection parameters and confirm that the appropriate driver is installed. Connection to [IP]:[Port] refused. Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections."
I am literally in despair, don't know what I'm doing wrong. Will be very grateful with anyone who can help me.
You need to add the jdbc driver to connect to postgresql DB in the pdi-installation/lib directory, you just put the *.jar file there and restart spoon to have the library available.
That driver can be downloaded from postgresql downloads. The Community Edition of PDI only comes with a small number of jdbc drivers, for each type of database you need to connect to, you should check if the jdbc driver is available in that directory, and if it's up to date or if you need a more recent version of the driver.
This is a link for the official Pentaho documentation, looking for information in Hitachi Vantara documentation is becoming more and more difficult, they don't always clarify what steps apply only for the Enterprise Edition and are not available for the Community Edition: https://help.hitachivantara.com/Documentation/Pentaho/9.2/Setup/JDBC_Drivers_Reference
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 fairly new to Oracle SQL developer. As I'm trying to make a new connection via TNS, I'm getting this error down below which I've been looking to solve for a while fruitlessly.
Error Message:
Statut : échec -Echec du test : no ocijdbc18 in java.library.path
Assuming MySQL is a typo (You are using port 1521, which is the default port for Oracle database, also its giving you ODBC error, so I assume its an Oracle database. Remember that you can connect SQL developer to a MySQL database, so please clarify if you want to connect to a MySQL database rather than Oracle) your problem is due to lack of Oracle Data Base Connector driver (ODBC). From this link download the latest version of Oracle Instant client and install it on your machine. Then define ORACLE_HOME to the path of Instant client installation (To the actual installation folder, the one that contains folders like bin, network and so on) and restart SQL Developer, then you should be good to go.
P.S. : as #thatjeffsmith has mentioned correctly in the comments, it's not necessary to have Oracle Client and/or ODBC (or similar) drivers in order to connect to an Oracle database. Using basic as the connection type and adding the correct connection info would suffice. This Article in Oracle Magazine has extensively talked about the different connection types.
I have PostgreSQL 9.3 version. I have created database name db1 now I need it to share with other users who all are connected with the LAN's to connect other applications with the same database.
In SQL Server: We can do this by selecting server name with login details.
Question:
Is it possible in PostgreSQL?
If yes, how can do this?
What is the procedure?
You will need to modify pg_hba.conf to allow remote connections to the database. Information about pg_hba.conf can be found here.
After that, you can connect programatically with a connection string, or similar to your image, with a GUI application like pgAdmin.
To connect (remotely or locally) from pgAdmin choose File -> Add Server... and enter the connection information into the dialog box. Here's an example of the window:
Your client computers will also need to have PostgreSQL drivers as well. If you're doing this in Windows, you'll probably be using ODBC. The PostgreSQL ODBC drivers are here. Info on the connection string format can be found here.
Here's an example of what pgAdmin looks like:
I'm totally junior in this area :)
I have JAVA version 7 on my PC.
I want to connect my PostgreSQL database to NetBeans.
Based on my search I found that I should get JDBC driver. so I downloaded JDBC41 Postgresql Driver, Version 9.3-1100 jar files from here.
then based on what I found for connection remote Mysql, did similar changes to connect to my PostgreSQL database.
As you can see in the image, connection couldn't established.
Based on what my host says, I added my IP address to "Remote PostgreSQL Database Access" page of my host.
I'm not sure my host name is correct. I used Dedicated IP Address of my site.
Any suggestion would be appreciated. Thanks
My fault was entering wrong user name and pass instead of using user name and password of database :(
