I'm having trouble connecting form builder to oracle database. Every time i try to connect to database an error occurs saying ORA-12154: TNS: Could not resolve the identifier specified. I know about password and database but I'm not sure about username. How will I know my username?
The error message you saw usually comes when the Oracle Client isn't installed on your workstation. The Oracle Client will have the TNSNAMES entry that will point the Forms Builder to the right database.
As to what your username is, like Holodoc says, you'd have to ultimately talk to your DBA.

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 am trying to connect to DB2 database to import source structure. I tried using ODBC DB2 Wire Protocol Driver Setup. I provided IP Address, TCP Port, Location ( DB2 to Z/OS and Iseries), but when I click on test connection I get below error:
[Informatica][ODBC DB2 Wire Protocol driver][DB2]NULLID.DDOS510A DOES NOT HAVE PRIVILEGE TO PERFORM OPERATION PACKAGE ON THIS OBJECT.
Same method I tried in lower environment of DB2 and connection works. but in higher environment I get this error. ( I verified login in the database directly and my user id has login access).
This is not a programming question, it is about configuration.
The reason that it works on one database, but fails on another, is because only one of the databases has the correct permissions.
Ask the DBA to grant relevant privileges to the userid at the database.
You will find more details at the following IBM technote and also at here.
I'm trying to setup an easily-replicable (or even manual and I do it once a month or so) process for moving data from a large Azure PostgreSQL database to a more manageable Azure SQL database for end users that are most familiar with SQL Server. I've successfully connected to the PostgreSQL database via PGAdmin, so I know all my connection string info.
I started by installing the latest ODBC driver from here.
I then used a connection string which was given to me from the Azure portal, filled in the proper database name and password, and attempted to use the following drivers:
PostgreSQL ODBC Driver(UNICODE)
PostgreSQL ODBC Driver(ANSI)
I am getting the following error with either of them:
ERROR [IM002] [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
What step am I missing in this process? Or how best can I troubleshoot this?
After more research, I attempted to add the ODBC driver here:
And got the following error (I'm not sure why Tableau is relevant to this?):
Thank you.
Update: It seems to be problem with ElephantSQL, the service I'm using according to this
However, I dont know where to add this.
Exact error:
FATAL: 28000: no pg_hba.conf entry for host "host", user "username", database "template1", SSL off
Similar error to this problem. Even after adding SslMode=require, I still couldn't connect to the database.
<add name="DefaultConnection" connectionString="Server=serverip;Port=5432;Database=dbname;User Id=username;Password=pass;CommandTimeout=60;Preload Reader=True;"/>
Weird thing is that it tried to connect to template1 instead of database specified in the connection string.
Connecting through pgadmin is fine though.
It's because you're on a shared ElphantSQL plan and can only connect to your own database. Npgsql tries to connect to template1 for some reason when it's checking server version, creating new databases etc, ignoring the database name given in the connection string. We'll submit a bug report to Npgsql.
I am 4 years late to this party but had this issue with npgsql also and this question came up so hopefully this helps someone else in the same boat next time.
I was able to fix it by adding "EF Template Database=[MyDatabase]" to my connection string. The default for that value is "template1" according to npgsql documentation
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 :(
