While installing Oracle 10g software, at the end i got the following error message.
And then when i run SQLPlus.exe I can not sign in using Scott/Tiger username/password. I get this error message
"ORA-12560: TNS:protocol adapter error"
Whats the issue?
Also, At the end of installation, i get this screen which says Database Control URL is .......... iSQLPlus url is ......
but when I copy/paste this url in the browser i get
Network Error (dns_unresolved_hostname)
Your requested host "imccit101.imcc.ae" could not be resolved by DNS.
For assistance, contact your network support team.
What are these url's for and how can I use them?
You can check whether you have the necessary services installed related to oracle. There should be service for the oracle instance and Tnslistner. If you have them try start them manually.

I am trying to install Informatica Server.
During domain configuration repository database information I get database connectivity error.
Error: Test Connection Failed. Correct the database connection information and test the connection again.
But when I connect using same details through Oracle SQL Developer to this database, it works fine.
I am using service name and port number field from the TNS File, still getting this error.
I think you can check tomcat log, catalina.out logs. This will help on finding out real issue.
Go to command prompt and type ping localhost and see if its responding anything. May be you can use IP and check host file.
I am trying to login into my Oracle database as sys user through sqlPlus but I keep getting ORA-12560: TNS:protocol adapter error. One of the reason of this error is that oracle service not running however when I check services there is no OracleService there, there are only following services related to oracle and they all are already running.
Oracle - OraDb11g_home1TNSListener , Oracle - OraDb11g_home1clrAgent and Oracle MTS Recover service
Please help resolving this issue.
Use the "Database Configuration Assistant" and create an Oracle instance. This looks like a Windows installation of Oracle, so the assistant should be %ORACLE_HOME%\bin\dbca.bat.
recently I had to change my computer name and now I am getting this error whenever I try to connect to my local oracle 11g express edition database via OracelSQL Developer.
I have already changed my listener and
tnsnames(D:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN) to reflect the my
computer's new name but I am still getting this error.
Any help would be appreciated.
Thank you
You must be using operating system authentication OPS$ prefixed username. Connect with sys or system and fix your DB user account. Search for OPS$ user in Oracle documentation for more details.
I have oracle 9i already installed in my machine. I am trying to connect to the oracle but while connection i am getting "ora 12560 tns protocol adapter error" type of error. i have tried it with the default pass scott/tiger , system/manager..
When i tried to connect to the oracle using default credentials i am getting the above error.
is it the problem with the username and password ? if so how can i get the username and password which is already set ?
IME, ORA-12560 means the Oracle Universal Installer messed up your listener configuration.
Assuming you have an Oracle 9i Server installed on your computer, here's a list of things to check.
does "lsnrctl status" show your database instance?
does "tnsping my_service_name" work?
do tnsnames.ora and listener.ora contain entries for your database? Are the hostname / port etc. correct?
If the configuration is wrong, your best bet is to start netca, remove your existing listener configuration and re-configure it.
One question, though: Why do you want to run Oracle 9i? Do you have to support some kind of legacy application / database? (Oracle 11gR2 is so much nicer than 9i)
Start -> Run -> services.msc
Select the oracle service name and right click on it then select start.
When in try to start azure storage emulator i get the following error.

LocalDB is installed but is not functioning properly. You may be missing prerequisites. Make sure you have .NET 4.0.2 or higher installed.
No SQL Instance found.
One or more initialization actions have failed. Resolve these errors before attempting to run the storage emulator again. Please refer to go.microsoft.com/fwlink/?LinkID=248088 for more details.
I installed .net 4.0.2 also. I tried uninstalling and installing sqllocaldb as well.
Any help is highly appreciated.
I had the same problem.
After installing .NET framework 4.5, the problem is gone for me.
I was also facing same kind of problem when reinitializing Storage Emulator. I used "Autodetect" parameter at command prompt and it worked for me.
DSInit /sqlinstance:(localdb)\v11.0 /Autodetect /ForceCreate
Hope this help to you too.

It would be better if you can check again if local DB is correctly installed and started. Please refer to SQL Server 2012 Express LocalDB for more information.
