I am trying to find out with SQLEXPRESS is installed on a server by running the following
sqlcmd -S LT1183 -U uname -P pass123 -Q "SELECT ##servername"
If it is installed it gives out the server name but if its not, it throws the below error.
Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : Login timeout expired.
Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : TCP Provider: Error code 0x2AF9.
Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : A network-related or instance-specific error has occurred while establishing a connection to SQL Server. Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections. For more information see SQL Server Books Online.
I am looking for a way to suppress this error and instead show a custom error message. Is that possible?
Thanks in advance.
This may not be possible with sqlcmd, since the error stems from connecting the the server, which upon error immediately terminates the sqlcmd.
if you can use powershell, you may find some luck using invoke-sqlcmd.
Powershell Try Catch invoke-sqlcmd
I have installed Oracle 11g on my Windows 10 machine. I followed all preinstallation requirements.
When trying to log in to the Enterprise manager via this link:
https://localhost:1158/em
I get the error:
Internal Error has occurred. Check the log file for details.
I have found log files and it looks like this is the relevant entry:

I have tried to set the unique name in environment variables, I thought maybe Java was the problem so I updated my JDK to 8. I am still getting the same error, and my SQL Plus will not open, as soon as I put in the correct credentials it closes. Also I have configured a Listener and tested, test was successful.
I managed to fix the issue, turns out it was a time zone issue. The DB time zone and computer time zone were different. Thus the DB Console would not start and was giving the error "EM daemon is not running".
I fixed it by following instructions here.
Also note before I did that I completely uninstalled Oracle and reinstalled it. There were some issues on that install that were causing SQL not to run. But the above is what fixed the Internal Error I was getting.
Make sure the SYSMAN database user is not locked.
select username, account_status from dba_users where username = 'SYSMAN';
If the account status is not OPEN then
alter user SYSMAN account unlock;
Try restarting dbconsole
$ emctl stop dbconsole
$ emctl start dbconsole
When I run the sql developer and set the all data,click the connect but i get this error:
Status : Failure -Test failed: IO Error: Got minus one from a read call
I am beginner in Oracle. How can I solve that error?
I use 64-bit Windows7 and oracle 12c.
In my case the error is connected to a problem about the client's (SQL Developer) ojdbc8 driver and the Oracle 19.3 docker container. The solution for me was to set a system property on the client -- you can do it within the JDBC connection string):
jdbc:oracle:thin:#tcp://host:port/service?oracle.net.disableOob=true
This is the thread that lead me to the answer.
The cause of the error is described here:
https://support.oracle.com/epmos/faces/DocumentDisplay?_afrLoop=357910144923387
You can also solve this problem by dissabling OOB on server side in the sqlnet.ora:
DISABLE_OOB=ON
Another workaround is to use the ojdbc7 driver.
Hope this helps some of us.
From your inputs in the dialog, you are using port 5500. That port is what is used for EM Express. It answers to HTTPs traffic only. So in this case the -1 error message means the protocol negotiation failed. SQLDEV is trying to talk SQL*NET to something listening for HTTPs.
The port you are looking for is 1521 if it wasn't altered. If it was check the $ORACLE_HOME/network/admin/listener.ora for the proper port number.
You need set "tcp.validnode_checking = no" or comment this parameter in sqlnet.ora file then restart listener on db server and test again.
Try it.
I got the same issue but following steps worked for me, it seems Gaurav also has shared it already:
1.Go to the folder where you have installed the database (Like: F:\app)
2.Here you will be able to see many folders, go to product\11.2.0("your databse version")\dbhome_1\NETWORK\ADMIN
3.find listener.ora file and open as text file
4.Check for the port number in that file
5.Now provide that port number while doing connection in sql developer.
Seems you have enabled ACL on the listener.
You can follow these steps to avoid the error:
1. Go to directory $ORACLE_HOME/network/admin
2. Modify sqlnet.ora file with following parameter:
tcp.validnode_checking = no
3. If you don't want to disable this, you can put the machine names as follows:
tcp.invited_nodes=(machine1, machine2)
3. Bounce the listener.
Hope that helps
Ensure the DB is up and running and you can connect locally AS SYSDBA to the database using Oracle binaries owner (usually oracle:oinstall Unix / Linux user). If it does not work, probably you encounter a different problem.
Check privileges of an Oracle file on Unix / Linux host where database is running:
cd $ORACLE_HOME/bin
ls -ltr oracle
-rwxr-xr-x 1 oracle oinstall 136803483 Mar 16 20:32 oracle
Change permissions as below:
chmod 6751 oracle
ls -ltr oracle
-rwsr-s--x 1 oracle oinstall 136803483 Mar 16 20:32 oracle
Most of the answers out there for this problem point to using the wrong PORT number in your connection options, or similar. In my case, after a couple hours of searching, the reason showed to be something else.
Mind which user you are using when starting Oracle listener. You should do it with the oracle user, not as root. Otherwise you end up with listener files being created as e.g. user deamon group root instead of user oracle group dba. This in turn leads to:
TNS-12555: TNS:permission denied
TNS-12560: TNS:protocol adapter error
TNS-00525: Insufficient privilege for operation
Linux Error: 1: Operation not permitted
To check whether this is the case, go to
/var/tmp/.oracle
and list all files (ls -la). If you find out some of the s#* files being created by a root-group user, stop the listener (lsnrctl stop), delete the above files as root and restart the listener as oracle user.
Unfortunately sqldeveloper doesn't show the full stack-trace when reading "Got minus one from a read call". I could find the problem thanks to switching to SQL-Squirrel.
In my case, I was given wrong host and port. I typed "tnsping yourServiceName" in command line in window 10. It returns a different host and port, then I used the correct one in sql developer and it worked.
In my case, it happened when I was using Docker with Oracle 19C.
The workaround is to find the listener.ora file, change 'PORT' and restart the container, ORACLE DB, listener.
It is presumed to be an error that occurred when the host tried to access TCP because it was already LISENT (HOST) by another process.
(When accessing Docker, consider that in most cases, you are accessing localhost.)
I changed the port to 1523, and all the problems were solved.
Try to do what the link , or check listener directory permission, or use command /dbhome/bin/relink all
Try
Connection name: HR_ORCL
Username: HR ,
Password: hr ,
Connection type : local,
Role: SYSDBA
Click on connect.
It will work.
Actually, It is not database specific issue. it is related to port value generated by database during your installation. To overcome on this issue, please follow below.
Go to the folder where you have installed the database (Like: F:\app)
Here you will be able to see many folders, go to product\11.2.0("your databse version")\dbhome_1\NETWORK\ADMIN
find listener.ora file and open as text file
Check for the port number in that file
Now provide that port number while doing connection in sql developer.
Hope it will resolve your issue.
I constantly get the following error when opening the test explorer in VS2013:
Failed to initialize data storage for staging test results as it threw the following exception:
'A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 50 - Local Database Runtime error occurred. Error occurred during LocalDB instance startup: SQL Server process failed to start.
In the EventViewer I see the following entry:
Source: SQLLocalDB 12.0
Message: Windows API call WaitForMultipleObjects returned error code: 575. Windows system error message is: {Application Error}
The application was unable to start correctly (0x%lx). Click OK to close the application.
Reported at line: 3728.
Does anybody have the same problem and know how to get rid of this error?
Best regards
Yannik
Finally, I found a solution that worked in my case.
Delete the instance folder of local db called "v11.0" (C:\Users\theUser\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\v11.0)
Start cmd window and execute the following command: sqllocaldb create "v11.0"
After this, the problems within the test explorer were solved.
Yannik had the solution....local DB (v17) is now called MSSQLLocalDB.
Delete "MSSQLLocalDB"
(C:\Users\theUser\AppData\Local\Microsoft\Microsoft SQL Server Local DB\Instances\MSSQLLocalDB)
Create a new one.
sqllocaldb create "MSSQLLocalDB"
I am trying to make a connection using Toad to a database (xe10 free edition) and it givea me a error:
ORA-12154
I tried changing the sqlnetORA to:
SQLNET.AUTHENTICATION_SERVICES= (NONE)
and still the same error.
1st check to make sure you can ping the database, if yes move to next step if not resolve firewall/network issues.
2nd check to see if you can connect via SQL*plus. If you can connect with SQL+ then your TNS is fine and Toad seems to be the issue, if you cannot then there is an issue with your TNS file.
Be sure to try and connect directly using the following method:
In Toad click "Session" > "New Connection"
There are 3 options TNS, Direct, LDAP (Shown as Tabs) . Select "Direct"
User: sys
Password : <passwd>
Host: 127.0.0.1
Port: 1521
Service Name: XE
Connect as: SYSDBA
If you are unable to connect via SQL+ or Toad then fix your .tns, I have attached a few helpful links below which should help resolve your problem.
http://www.dba-oracle.com/t_ora_12154_tns_resolve_service_name.htm
http://www.orafaq.com/wiki/Tnsnames.ora
try to comment the following line in sqlnet.ora
#names.default_domain = world
otherwise, Oracle will append .world to your host string
Often, it's a typographical error in your connexion string or in your tnsnames.ora file. More information here : 11g/ORA-12154.
