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 :(

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 just installed Oracle Database 11g Express Edition.
In the Run SQL Command Line window I connected to database with username:SYSTEM and password:{password I selected during installation}
SQL>connect SYSTEM/{password}
Then I created a user with password as described in the documentation. After that, I am able to access the database i.e. creating and querying tables and info.
Now, I want opened latest Eclipse EE and opened a Database Development perspective. In the Data Source Explorer, I right clicked and selected New Connection. In the driver definition, I added the jar file ojdbc6.jar which is provided in the oracle installation.
I don't know what to fill in Host, Username, and Password. I tried several combinations, and still getting ping failed. Please help, I am trying it for 3 days now and got so frustrated.
To check the host name -> ORACLE_HOME/server/network/admin
open the tnsnames.ora file with oracle developer. You will see somethimg like this-
ADDRESS = (PROTOCOL = TCP)(HOST = hostname )(PORT = 1521
now in eclipse-> windows->preferences->data management-> connectivity -> driver definition
there add oracle thin driver 11 and include necessary jars(u will find them in your \oraclehome->jdbc->lib ,then in properties in the connection url field include url with ur hostname you checked in tnsname.ora
example -jdbc:oracle:thin:#hostname:1521:xe
I know, u are welcome.. i too spent 4 days in figuring this :)
I have installed the DSP(Dreamfactory Service Platform) locally on my Mac Book Pro using Bitnani.
I have a PostGreSQL server running locally on my Macbook, which I want to connect to using the DSP.
I am successfully able to connect to my PostGreSQL server from other applications, which essentially means that there is no problem with the setup.
However, on trying to connect the same from DSP I get the error:- "Failed to launch service "sql": CDbConnection failed to open the DB connection."
My connection string is :- "pgsql:host=localhost;dbname=Pinu"
Also, the password has been correctly entered.
The port is default as 5432. Whether or not I enter the same in the connection string, the connection always fails.
Even though I am trying to add the service as Remote SQL DB, I know that it's actually on the same local host. Not sure if that is the issue.
I also tried entering - 127.0.0.1 in place of localhost, but still I see the same issue.
Any help in this regard would be highly appreciated!
After talking to you via email, it looks like the root issue here is that you haven't successfully upgraded your DSP to the latest version. We are releasing DreamFactory version 1.8 on Bitnami tomorrow, so you should upgrade to the latest version.
As far as your PostgreSQL issue let's explore some options:
1) Connection strings:
a) pgsql:host=localhost;dbname=Pinu
b)
pgsql:host=localhost:5432;dbname-Pinu
c)
pgsql:host=localhost;port=5432;dbname=Pinu
2) If these don't work, try substituting your localhost with
127.0.0.1 (as you've tried previously, but test this in all scenarios).
3)
pgsql:host=localhost;port=5432;dbname=series1;schema=schema_name_here
Typically, Option A should work without a problem.
Give these a try if you would, and if you need some help upgrading then reach out to me again via email.
--Thanks,

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 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.
