I have already installed sqldeveloper and i can launch SQLdeveloper client on my Linux Ubuntu 16.04 system.
The problem occurs during the first attempt of the new oracle connection from the client.
Error returned:
"I/O: The Network Adapter could not establish the connection"
I have already tryed several times to connect at the database but i still missing the username and password.
Is it possible to configure username and password for SYS/SYSTEM(or who else) user after installation?
Full stop.
You don't have a database.
Installing SQL Developer is just giving you a client you can use to work with an existing Oracle Database, which we often refer to as the 'server.'
SQL Developer is not a database.
So you need to get one.
Then you can use SQL Developer.
You have a few options. I talk about them in detail here.
SQL developer is just like the Key for Safe lock. And Database is the Safe.
So right now you have the key for Safe but doesn't have Safe.
Please get the safe first.
SQL Developer is not the Database. So Installing SQL developer will not give access to DB
Instead SQL Developer is the client side tool to retrieve the data or to do the modification on Database.
To get the database you need to download oracle DB from below link

I have a database Connection established in odbcad and Microsoft Access (aswell as working in Excel) via ODBC and want to also get it working in Oracle SQL developer.
It is a Windows SQL Server as far as i know and I have tried several Settings, of which None works. I have also installed Driver for ODBC. I would like to Import Settings into SQL developer as applied in MS Access, is there any possibility?
No, SQL Developer is a Java application and uses a JDBC driver.
But if you look at the odbc properties for your connection, those should largely translate to what you need to define a basic connection.
Oracle:
Server name or IP address of the DB, port # for the listener, and the name of the SID or Service, plus a valid username and password is all you need to connect to Oracle.
What error do you get when you try to connect?
Show us what you're trying.
Update:
You're trying to connect to SQL Server but you're getting"
Native SSPI library not loaded
You're trying to use OS Authentication for your connection. For this to work with the jTDS driver, you need to copy a DLL file named ntlmauth.dll (which is for NT authentication) under the jtds-x.x.x-dist\x86\SSO\ or jtds-x.x.x-dist\x64\SSO\, to any directories in the PATH environment.
Please update your question such that's it's clear you're connecting to SQL Server and share the error message so others can find it.
I imagine this question is a duplicate of many previous iterations of the same challenge.
I've installed sqlplus64 throw this tutorial: http://webikon.com/cases/installing-oracle-sql-plus-client-on-ubuntu
I want to practice SQL using sqlplus (I can't connect remotely to school ssh).
I've tried everything I found in google and still can't connect.
I don't have any credentials
sqlplus64 / as sysdba
ERROR:
ORA-12545: Connect failed because target host or object does not exist
Welcome!
Probably the easiest way to get started with SQL using sqlplus is to use the virtual machine image Oracle provides for the hands on lab. It contains not only sqlplus, but a full Oracle 12c database, already configured correctly.
Download and instructions here. It's free. You'll need a free account on OTN (Oracle Technology Network), but that's necessary anyway to read the documentation about SQL*Plus and all the rest of it.
We have a large SSIS solution with many connection managers pointing to Oracle. Provider is ODBC, data sources are set to defined system DSNs. So far we use user names and passwords and everything works fine. Now we want to switch to Kerberos authentication.
I can already successfully query the Oracle database using sqlplus with Windows authentication.
I'm having hard time achieving the same from SSIS using ODBC connection managers.
Is it possible to reconfigure the ODBC connection managers so they will use Windows authentication? How should be the connection manager configured?
The question is specifically about ODBC, please avoid answers like "use Attunity".
We use MS SQL Server 2016 Enterprise edition, Oracle 12.2.
I finally made it working, hope it helps someone.
I created a new DSN
as User ID I put [OracleUserName]
beware the square brackets! Those are necessary
the OracleUserName is user name configured on Oracle side (I do not know much about Oracle). The DBA configured the AD account to be able to login as this user.
I am new to Programming. I am learning JAVA and for DB i wanted to learn Oracle so I downloaded sqldeveloper from Oracle website. It was a zip file so I didnot have to install anything, simply extracted it. When I open the sqldeveloper and try to make a new connection, it shows error.
Test failed: IO Error: The network adapter could not establish the connection.
I am not sure what to put in username and pwd. and i am also not sure if i have to connect this to jdk or jre or set classpath for database.
Can anyone help me?? I have uploaded the snapshot of the error too.
You downloaded a client.
You did NOT download the server component though - the actual database.
SQL Developer just allows you to work with an existing database.
No worries, you're not that far away. You have several options.
Oracle Database Express Edition (XE) - it's completely free.
We also have a VirtualBox appliance you can use for personal learning purposes, also completely free.
I talk about this and give step by step instructions here.
Check if oracle service, TNSListener service is up and running before trying to make any new connection from sql developer.
Even if TNS Service is down , connection can not be established with oracle instance.
I only have SQL Developer installed. What other programs do I need to install to create a local database. Please provide links.
SQL Developer is a client that access to a database server to extract data.
You need a database server.
If you operate with SQLDeveloper probably you like to install Oracle. There is a simplified version of Oracle that is called Oracle-XE. Search it over google and download the right version for your operating system.
Give the username and password of the user you created. You can specify localhost in Host name. If you haven't modified the port on which Oracle works then give 1521. If you haven't changed SID as well then give XE. You might be able to connect with DB.
