I'm new to Grafana and trying to connect Grafana to Microsoft SQL Server. I run both Grafana and SQL server on the same machine with Windows OS. In Grafana, I selected SQL Server data source and provided Host and DB name. I created a user in SQL server and granted reader permission to the user as per https://grafana.com/docs/grafana/latest/datasources/mssql/. Either for SQL server Authentication or Windows Authentication, I get the error db query error: failed to connect to server - please inspect Grafana server log for details.
I checked then Grafana log file: lvl=eror msg="query error" logger=tsdb.mssql err="Unable to open tcp connection with host 'servername:1433': dial tcp [2a02:908:1391:9e80:c180:xxxx:xxxx:xxxx]:1433: connectex: No connection could be made because the target machine actively refused it."
How can I force SQL server to give access to Grafana?
I should mention that, I haven't changed Grafana conf file. Do I need to change the default conf or create another conf file?
The default DB configuration in Grafana conf file is:
[database]
# You can configure the database connection by specifying type, host, name, user and password
# as separate properties or as on string using the url property.
# Either "mysql", "postgres" or "sqlite3", it's your choice
type = sqlite3
host = 127.0.0.1:3306
name = grafana
user = root
# If the password contains # or ; you have to wrap it with triple quotes. Ex """#password;"""
password =
# Use either URL or the previous fields to configure the database
# Example: mysql://user:secret#host:port/database
url =
# Max idle conn setting default is 2
max_idle_conn = 2
# Max conn setting default is 0 (mean not set)
max_open_conn =
# Connection Max Lifetime default is 14400 (means 14400 seconds or 4 hours)
conn_max_lifetime = 14400
# Set to true to log the sql calls and execution times.
log_queries =
# For "postgres", use either "disable", "require" or "verify-full"
# For "mysql", use either "true", "false", or "skip-verify".
ssl_mode = disable
# Database drivers may support different transaction isolation levels.
# Currently, only "mysql" driver supports isolation levels.
# If the value is empty - driver's default isolation level is applied.
# For "mysql" use "READ-UNCOMMITTED", "READ-COMMITTED", "REPEATABLE-READ" or "SERIALIZABLE".
isolation_level =
ca_cert_path =
client_key_path =
client_cert_path =
server_cert_name =
# For "sqlite3" only, path relative to data_path setting
path = grafana.db
# For "sqlite3" only. cache mode setting used for connecting to the database
cache_mode = private
The settings in Grafana's configuration file refer to its internal database so you do not need to change any of these to connect to MS SQL Server.
Try using "localhost" or "127.0.0.1" as the host name
Make sure authentication is SQL Server Authentication
Make sure Encrypt is false
Check the SQL server logs for any errors
Docker host using IP address of your machine follow below steps:
Open the CMD
IPCONFIG /ALL
Look for the IPV4 address under WiFi or
vEtherner; in my case, it's 192.168.1.24 and 172.45.202.1, respectively
Then try accessing the app hosted in the Docker container with the mapped port (e.g., 1433/5436)
It simply worked using 192.168.1.24:1433 and 172.45.202.1:1433 in the same way to access all container apps hosted using Docker
This is our first SSIS package created on xx.xx.xx.77 for pull data from xx.xx.xx.56 server and load on share path (server ip xx.xx.xx.130) as an Excel file. That path is accessible from both servers.
SQL Server Agent is configured with NT Service\SQLAgent$instance in xx.xx.xx.77 server.
So we got Error1.

After Google search we go with Proxy user. Now we facing issue (Error2) in scheduling that package on xx.xx.xx.77 server using proxy user.
Error2:
The job failed. The Job was invoked by
User. The last step to run was step 1 ()
FYI: Although same Proxy user has been created on xx.xx.xx.55 server, same error persist while run job on 77 server.
Reference Links:
Give access to virtual account. But we cant do this due to our privileges is not enough.
Proxy Creation
We refer more SO Q&A and Google results for SSIS package creation. No one helps. Because our scenario includes two servers. So we need helping hand.
Edit 1:
We did this after Error1.
"Launch & Activation Permission" -> click Edit -> Add in the account NT Service\SQLAgent$instance-> Name Not Found error. Ref: below image. Same error for, add "Service Account" in Object Type on below dialogue box.
Then we change location from Domain.com to Server Name in Location as follows:
Now, NT Service\SQLAgent$instance name is found. Then we check "Local Launch & Local Activation". Ref:
After restart the Service, we got same error. Thats' we go with Proxy User.
Reference link for Deploy the SSIS package.
EDIT 2
We move the SSIS project to another xx.xx.xx.231 server, where SQL Service Agent is configured with Domain user like backupuser#domain.com. Now the job is run successfully on scheduled time.
FYI: Another reason of the error is the destination file is may be opened by another user. Here, file is in shard location. When run the job on xx.xx.xx.231 server, we got same error again. After some cross checking, we found that Excel file is opened by our Team met.
Thanks to All,

You might need to provide permission using the below instruction.
Click Start -> Run -> Type -> dcomcnfg, expand Component Services -> Computers -> My Computer -> DCOM Config.
Click View -> Detail -> Now you will get Application Name and Application ID in right side.
Scroll down and find the application ID " " -> Right Click -> Properties and select the Security tab.
Click Customize under "Launch & Activation Permission" -> click Edit -> Add in the account NT AUTHORITY\SYSTEM and set local launch and local activation.
Restart the application Service linked to this Application ID or restart the server and monitor
Recently I set up AG and server X is Primary and Server Y is secondary and Z is listener server. Ag is running fine. If I do RDP to Primary Server I can connect to Listener but Can't connect through Secondary server and from my local SSMS,I can't connect to listener at all.
We have Azure environment and I set up load balancer, Front end ip and health probe.
I checked all configurations are correct or not. There are no firewall issues.
compared with other listeners also.
can someone please help me, what I am missing..
I found the Solution.DNS was not able to communicate with Listener server.So need to run this powershell script and It worked.I am attaching link for reference.

I Google[d] for this error ORA-12560: TNS:protocol adaptor error but not able to find the actual reason and how to solve this error ?
Can anyone tell me a perfect solution to solve login problem.
Go to the windows machine that hosts the Oracle database server
Go to Start -> Run -> Services.msc in Windows.
Locate OracleService < SID > (here OracleServiceORCL) and click on Start to start the oracle database service (if not already running)
Once it is up and running, from the command prompt run the following:
tnsping < tnsalias >
(tnsalias entry you can find it in tnsnames.ora file)
In my case I didn't have an OracleService (OracleServiceORCL) in Windows Services.msc as described in Bharathi's answer.
I executed this command:
C:\> ORADIM -NEW -SID ORCL
and then the OracleService called OracleServiceORCL just showed up and got started in Services.msc. Really nice.
Source: https://forums.oracle.com/forums/message.jspa?messageID=4044655#4044655
Seems like database is not up. It might be due to restarting machine and the instance is not set to autostart and it so not started munually after starting from services Screen.
Just goto Command prompt
Set Oracle SID
C:>set oracle_sid=ORCL
Now run Net start command.
C:>net start oracleserviceORCL
from command console, if you get this error you can avoid it by typing
c:\> sqlplus /nolog
then you can connect
SQL> conn user/pass #host:port/service
Add to the enviroment vars the following varibale and value to identify the place of the tnsnames.ora file:
TNS_ADMIN
C:\oracle\product\10.2.0\client_1\network\admin
In my case (for OracleExpress) the service was running, but I got this issue when trying to access the database via sqlplus without connection identifier:
sqlplus sys/mypassword as sysdba
To make it work I needed to add the connection identifier (XE for Oracle Express), so following command worked ok:
sqlplus sys/mypassword#XE as sysdba
If you still get ORA-12560, make sure you can ping the XE service. Use:
tnsping XE
And you should get OK message along with full connection string (tnsping command is located in oracle's installation dir: [oracle express installation dir]\app\oracle\product\11.2.0\server\bin). If you can not ping make sure your tnsnames.ora file is reachable for sqlplus. You might need to set TNS_ADMIN environment variable pointing to your ADMIN directory, where the file is located, for example:
TNS_ADMIN=[oracle express installation dir]\app\oracle\product\11.2.0\server\network\ADMIN
After searching alot got a simple way to solve it.
Just follow the steps.
Check status of your listener.
open command prompt and type lsnrctl status
You will get no listener.
Now open listener.ora file which is present in following directory: C:\oraclexe\app\oracle\product\11.2.0\server\network\ADMIN
Open that file and change the host parameter with you computer name
You can get your computer name by right click on My Computer and check you computer name, and replace host parameter with your computer name as follows:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = Electron-PC)(PORT = 1521)
)
)
)
So here you can observe HOST = Electron-PC, which is my computer name.
Save the listener.ora file and again return to cammand propt
3.Type the following in command prompt lsnrctl start
This will start the OracleTNSListner.
you can check it in the service by opening services tab of Task Manager. if not started automatically you can start it.
Just this much and you are ready to work again on oracle.
Best of Luck.
Quite often this means that the listener hasn't started. Check the Services panel.
On Windows (as you are) another common cause is that the ORACLE_SID is not defined in the registry. Either edit the registry or set the ORACLE_SID in a CMD box. (Because you want to run sqlplusw.exe I suggest you edit the registry.)
I have solved the problem the easy way. My oracle was running just fine in the past. After I installed MS SQL Server was when I noticed this problem. I just uninstalled MS SQL Server on my machine then the problem was gone. Make sure you restart your computer after that. Now I can connect to Oracle database through SQLPlus again. My guess is that there's some conflict between the two. Hope this helps.
Another possible solution that just worked for me...considering I was using my local login as the dba permissions.
Follow the steps to get to Services. Right click on the instance and go to 'Log On'? (might not be the name but it's one of the tabs containing permissions). Change the settings to use LOCAL.
If none the above work, then try this :
Modify the LISTENER.ora (mine is found in : oracle\product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora) ==> add a custom listener that points to your database(SID), example my SID is XZ0301, so :
## Base XZ03001
SID_LIST_LISTENER_XZ03001=(SID_LIST=(SID_DESC=(ORACLE_HOME =
E:\oracle\product\11.2.0\dbhome_1)(SID_NAME= XZ03001)))
LISTENER_XZ03001=(DESCRIPTION_LIST=(ADDRESS=(PROTOCOL =
TCP)(HOST=MyComputerName)(PORT= 1521)))
DIAG_ADR_ENABLED_LISTENER_XZ03001=ON
ADR_BASE_LISTENER_XZ03001=E:\oracle
Restart your machine
For Windows 7, use the following to modify the LISTENER.ora:
- Go to Start > All Programs > Accessories
- Right click Notepad and then click Run as Administrator .
- File>open and navigate to the tnsnames.ora file.
- Make the changes then it should allow you to save
It really has worked on my machine. But instead of OracleServiceORCL I found OracleServiceXE.
Flow the flowing steps :
Edit your listener.ora and tnsnames.ora file in
$Oracle_home\product\11.2.0\client_1\NETWORK\ADMIN location
a. add listener.ora file
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
)
)
ADR_BASE_LISTENER = C: [here c is oralce home directory]
b. add in tnsnames.ora file
SCHEMADEV =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = dabase_ip)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = SCHEMADEV)
)
)
Open command prompt and type
sqlplus username/passowrd#oracle_connection_alias
Example : username : your_database_username
password : Your_database_password
oracle_connection_alias : SCHEMADEV for above example.
Just to add up, follow the screenshot and choose local account to start if not selected. Then start the service.
You need to tell SQLPlus which database you want to log on to. Host String needs to be either a connection string or an alias configured in your TNSNames.ora file.
ORA-12560: TNS:erro de adaptador de protocolo
set Environment Variables: ORACLE_BASE, ORACLE_HOME, ORACLE_SID
make sure your user is part of ORACLE_GROUP_NAME (Windows)
make sure the file ORACLE_HOME/network/admin/sqlnet.ora is:
SQLNET.AUTHENTICATION_SERVICES = (NTS)
(Windows) Be carefull when you add a new Oracle client: adding a new path to the PATH env. variable can mess things up. The first entry in this variable makes a difference: certify that the sqlplus executable in the ORACLE_HOME (ORACLE_HOME/bin) comes first in the PATH env. variable.
I try 2 option:
You change service OracleService in Service Tab -> Running
Login with cmd command: sqlplus user_name/pass_word#orcl12C
Note: orcle12c -> name of OracleService name run in you laptop
Below fixes can be applied to resolve TNS 12560 error
Get Latest patch for SQL*NET client software
Set $ORACLE_HOME and $PATH variable (should be accessible for System user)
Check permissions on PC client
Check $TNS_ADMIN variable
Check if network has firewall or antivirus issues
Check if windows services Run >> Services.msc has OracleXE or OracleORCL service running
Check below link in case of net tracing error:
http://dba-oracle.com/t_sql_net_tracing.htm
In my case, (ORA-12560: TNS protocol adapter error)Issue cause of database connection issue like database, user name and password.
Once you got the issue. Initially you have to check connection details, after check the oracle service and further more.
I missed some connection details, So only i got TNS protocol adapter error,
I will changed the connection details, It would be working fine.
I am trying to accessing my Oracle database over Network. I have Google a lot and found many solutions, but those doesn't work for me.
The problem is that, I want to access my Oracle Database from One Computer to another Computer over my Local Network.
What I did is....
I found a Solution to modify listener.ora file with
(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=dbp.devProject.com)(PORT=1521)))
When I modify this file and tried to run and access the Database nothing will happens, and it throws an Error, the port number you have specified is used by another listener, so i have changed port Number but I am not able to access Database.
2. I have configure a new listener with the help of oracle's tool Net Manager, which made a Listener for me, but it does not make accessible database over Network.
Here Some required results.

Someone please Help me.
Thanks for your Help..
Whenever you encounter this kind of errors while creating remote access for you database, follow these steps beforehand.
Create a Listener using Net Manager tool of Oracle or create it Manually.
After generating Listener, check out "listener.ora"
[Located : ORACLE_INSTALLED_DIR\product\11.2.0\dbhome_1\NETWORK\ADMIN]
file, for your entry. (is there any Entry for the Listener which you have created just before. If you found your Entry than and than do next steps otherwise do it from FIRST step.)
If you found the Entry for your Listener, Open Command Prompt and fire command lsnrctl status. This will give you all currently running Listeners List, find out the one which you created just before.
Check out the Host Name and Port Number for your Listener.
Generate the Connection String as per the details you found in lsnrctl status
Connect with Database, and You can access the Database from anywhere in your Network.
If your host name and port number is listener then You could try this option by enabling port number in firewall settings.
Opening Ports in Windows Firewall
Open the Control Panel. ...
Open Windows Firewall. ...
Click the Advanced Settings link. ...
Select "Inbound Rules". ...
Create "New Rule" under "Inbound Rules". ...
Select "Port" from the first screen of the wizard. ...
Choose TCP or UDP. ...
Enter in the port range. ...
Finish the wizard.
Create an entry in TNSNAMES.ORA file on the system from which you are trying to connect to the database. (TNSNAMES.ORA is located in ORACLE_INSTALLATION_PATH/Network/Admin/ folder)
Sample entry:
DB_HOST_NAME =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = DB_HOST_NAME)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)
If you have more than one Oracle clients installed, you might need to update this in all those TNSNAMES.ORA
