im using oracle sql developer to make my database, but now i stopped to work.
it wrote this:
An error was encountered performing the requested operation:
Listener refused the connection with the following error: ORA-12514,
TNS:listener does not currently know of service requested in connect
descriptor
Vendor code 12514
i also tried to make new connection but it didnt help
pls help me,i dont know what to do, i need this to do my homework
when i tried to change connection it wrote this:
An error was encountered performing the requested operation:
ORA-01031: insufficient privileges
01031. 00000 - "insufficient privileges"
*Cause: An attempt was made to change the current username or password
without the appropriate privilege. This error also occurs if
attempting to install a database without the necessary operating
system privileges.
When Trusted Oracle is configure in DBMS MAC, this error may occur
if the user was granted the necessary privilege at a higher label
than the current login.
*Action: Ask the database administrator to perform the operation or grant
the required privileges.
For Trusted Oracle users getting this error although granted the
the appropriate privilege at a higher label, ask the database
administrator to regrant the privilege at the appropriate label. Vendor code 1031
Please check the services are running:
OracleOraDb11g_home1TNSListener and OracleServiceORCL.
You're going to have to do some troubleshooting; Here are a couple of suggestions:
ORA-12514 Tips
ORA-12514 TNS:listener does not currently know of service requested in connect descriptor
How to resolve error: ORA-12514
The service name ,you are using should be in sid column and not in service name entry box.
For example, the service name provided for you is overflow,you have to mention it in
ex:10.171.1.24:1521:overflow
Sid : overflow
Service : leave blank
Test the connection
Go to Services
check whether the "ORACLEServiceORCL" is running or not.
if not running then right-click on it and click start.
Your problem may solve this.
Happy coding :D
This worked for me- Close your SQL Developer and launch again.
I had the same issue after restarting my PC and could not access my local database. This fixed it.
Go to Run > services.msc > Services (Local) > OracleService
Right-click on OracleService > Properties > Log On
Make sure Local System Account is checked then press OK.
Stop the OracleService and restart it. It should be working now.
Mine was working fine till last night but this morning I found the said problem. I checked OracleOraDb11g_home1TNSListener and OracleServiceORCL was running and in "Started" status but still issue was there.
Just restarting both the services solved my issue. I suggest just try this once to save your time before exploring other solutions.

I am trying to connect mysql database with mulesoft database connector, but it is giving error while I do test Connection. I am not able to figure out what is wrong I am doing. Could you please put me in right direction?
Please ask for more information you need from me.
The problem you are facing is not because of Mule component.There may be several other reasons at MySQL side.
As you can see that your credentials are processed by MySQL however denied.This suggests that the problem may not be directly
related with credentials because if credentials were wrong the error would have been different then denied.
When credentials are denied, the problem is mostly related with:
Permission issue - Solution >> Grant permission to use "db_name" from "Localhost"
Your connection string looks fine but sometimes string encoding result this error
Some installed components are interfering with MySql -> Check the components installation
Also
LOCALHOST and "machine name" aren't the same to MySQL.
I'd check from the command line that you can connect to localhost:
mysql --user=<user_name> --password db_name
Enter password: your_password
If it fails, connect and run this with the appropriate permissions:
create user db_name#localhost identified by 'db_name';
grant select on <user_name>.* to db_name#localhost;
Never mind :) I found the solution although did not find what the problem was only suspecting that the root was not having any schema privileges ( as shown by MySQL Workbench GUI).
Earlier I was using command line with which I am not well versed; after struggling a little I downloaded MySQL workbench and added one more user with all administrative and schema privileges and used that to connect with Database connector and God Damn!! it's working.
I am learning the sql server 2012 and got stuck when using the copy datase, trying to figure out why.
I created two instances on the same host, using administrator, windows authentication.
(the default instance:iZp0w14yqtvxcmZ, the second instance: iZp0w14yqtvxcmZ\instance2, try to copy database from the default one to the second one)
It failed at the last step: execute sql server agent job.
here is the error log from windows event viewer:
Message: Failed to connect to server iZp0w14yqtvxcmZ.
StackTrace: at Microsoft.SqlServer.Management.Common.ConnectionManager.Connect()
at Microsoft.SqlServer.Dts.Tasks.TransferObjectsTask.TransferObjectsTask.OpenConnection(Server& server, ServerProperty serverProp)
InnerException-->Login failed for user 'NT Service\SQLAgent$INSTANCE2'.
Then I tried to add the login 'NT Service\SQLAgent$INSTANCE2' in the default instance. Then tried again and got another error:
Event Name: OnError
Message: An error occurred while transferring data. See the inner exception for details.
StackTrace: at Microsoft.SqlServer.Management.Smo.Transfer.TransferData()
at Microsoft.SqlServer.Dts.Tasks.TransferObjectsTask.TransferObjectsTask.TransferExtraObjectsViaSmoTransfer()
InnerException-->Windows NT user or group 'iZp0wd5ebkvswaZ\Administrator' not found. Check the name again.
But the Adminitrator does exist in the computer management -> local user and groups -> group, so I don't know what to do now. NEED HELP !!!
Thanks a lot!
after two-day's struggling, I figured it out. The sql server agent service should use a domain-based account for a multi-server environment. Also that account should be able to log in and perform the job.
I solved the issue changing the login method to system local account.
Two instances must have the same password and open, then in this case:
insert into [EI7-PC\SQLEXPRESS2].[MYCOMPANY].[dbo].[inventory] SELECT *
FROM [EI7-PC\SQLEXPRESS1].[MYCOMPANY].[dbo].[inventory] where itemno='10-0001'
The reason for the same password is unknown, this is per my experience. With two different password you may get an error about 'sa' failed to login.
Right, when I logged in using a domain account for my database on the SQL Server Reporting Services, it worked absolutely fine, however on another machine I have entered the wrong password by accident and now it will not let me log in again. I've tried clearing the internet cache, stored passwords etc... and still no luck. So currently I am locked out of the report server on a machine.
Is there a way to make it forget so I can login from scratch?
Cheers for any help
Error:
The permissions granted for user 'domain\username' are insufficient
for performing this operation. (rsAccessDenied)
I know they are not insufficient as I use my account on another machine no issues.
Try a different browser first. If that doesn't work, try clearing the stored passwords off your system.
You can refer this.
the login and password works, that's not the issue. please open internet explorer as an administrator (right-click, run as administrator), open http://localhost/Reports/ and check under "site settings" on the top right corner that the permissions are set correctly.
I want to get the process in a remote system using vb.net for that i have use getProcess() method. when i am trying to execute the code it is showing an error like "Couldn't connect to remote machine" .i know there should have certain privilege to use this.but i don't know how to set the privileges and what all are it. if any one knows please help me
sorry for my bad english.
The information from this blog post might be helpful:
Here is a list of common errors I had while working with the
System.Diagnostics.Process class. I listed all solutions that worked
for me.
Solution 1: Open MMC (Start/Run/mmc), add the Services snap-in and
enter the name of the machine you are trying to connect to. This
should give the exact reason it’s failing.
Solution 2: The inner exception could give you more information.
Solution 3: You need server permission.
Solution 4: Common on Windows 7 and Vista, start the Remote Registry
service.
Scenario:
If i try to start the server as a window service it gives an error stating that ceradentials are not correct.However on correcting the credentials in boot.properties when i try to start the server again it gives the same error.Any alternative for starting the server.I gave the same username and password in my startup Script and Boot.properties.
Scenario 2: If i start the server remotely through console then will it come up?
Thanks in advance.

Preet
If i try to start the server as a window service it gives an error stating that credentials are not correct.
Then they aren't. Maybe provide more details on what you do exactly and the error message.
If i start the server remotely through console then will it come up?
First, if your credentials are not correct, then it won't change anything. Second, if you don't have a node manager configured, this won't be possible. Provide more details.
