I am new to oracle database and i was trying to set up SQL developer.After installation when I open it and make a new connection it gives me "IO error: the network adapter could not establish the connection".I tried to look up for the solution everywhere but nothing worked.Can someone please explain me in detail hoe to fix this thing?
You have installed SQL Developer, the client.
It's effectively limited to working with files and offline data models.
If you want to do database work, you need a database.
Here's your options for getting started.
You have to start the listener with
lsnrctl start

I use Pentaho to migrate data from SQL server to MySQL. Unfortunately, the connection to MySQL is not stable and it sometimes failed in the middle.
Is there any option in Pentaho that allow Reconnect to MySQL when the package lost connection then the Pentaho package can continue running.
Thanks,
Try creating the DB connection using the wizard rather than using the new button.
I am using a share connection, so I just select connection name in the "Connection"
I applied a work around to by pass this case. That is auto retry logic which include a loop if ERROR and still have data then I go back some steps.
I am facing the below error while connecting Tableau with oracle database.
below is the screenshot for reference :
please suggest steps to fix this.I am very new to Tableau and database things.
You need to make sure that connection information with Oracle Database is correct, which includes host name, port name, username and password. Above this you should make sure your server is up and running
Every time I try and create a new database and a new server in Azure, I am greeted by this cloud icon
Then when I press ok in the Add data connection tab, I am prompted by this error:
There was an error while creating data connection 'Storage data connection - ma7b51a363647f41'.
I have seen the other SO posts about this error, but none of the solutions such as
Delete all your other database connections and services
Retry the process
work for me.
I have exactly same problem. I try same things and still error appears. I find another solution in my problem, I created new Mobile Apps Quickstart and then i created new DB and data connection successfully. I hope this will help you little bit if you are struggling with app services too.
I'm using Oracle SQL Developer 3.0.04. Trying to connect to a remote DB. Don't have any issues with database connection, it connects.
But when trying to view a selected tables rows a small progress bar within a small dialog box titled "Display Results" appears saying "Waiting for Checking if Object is Editable" and the progress is stuck. Cannot see any data of the selected table.
I tried to export the schema and data, but it freezed at once. So I closed SQL Developer.
Tried to attempt that again but now cannot even view the tables details.
Used TOAD in another machine and connected using that, no issue then the table listed all the data. Checked on the remote machine using putty and "sqlplus" to connect and the data showed as expected.
So that tells me that something in my local machine is wrong. Cannot connect using SQL Developer. Has anyone out there faced similar issue? please any idea on this matter?
Thanks
Did you try connecting to any other database, remote and local ? Does this happen with every database or only one connection? Perhaps something is wrong with that installation folder of SQL Developer, perhaps something got corrupt while it was stuck. Perhaps try to download the latest version of SQL Developer from this link and try again.
I have a database that I am trying to connect to through SQL Plus. I run this command from the command line:
sqlplus username/password#//hostname:port/sid
I use this connection string instead of using tsnames. The error I keep getting is
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in connect
descriptor
The weird thing is that using the same connection information I can connect just fine through SQL Developer. I can see the tables, users, and everything else. Anyone know what could be going on?
P.S. I tried setting up tsnames but it just gave the same thing as using the connection string.
So my boss found the solution. Turns out the sid is different when connecting through SQL Plus then through SQL Developer. Seemingly in just this one case. I have no idea why this is but that was the reason. Very odd and I don't understand why.
