I am trying out NLog to use mySQL table. I seem to have the configuration set correctly however I am getting the following error (capturing exceptions in NLog).
2012-10-10 17:09:20.0200 Error Error initializing target Database Target[slogger] System.Configuration.ConfigurationErrorsException: Failed to find or load the registered .Net Framework Data Provider.
at System.Data.Common.DbProviderFactories.GetFactory(DataRow providerRow)
at System.Data.Common.DbProviderFactories.GetFactory(String providerInvariantName)
at NLog.Targets.DatabaseTarget.InitializeTarget()
at NLog.Targets.Target.Initialize(LoggingConfiguration configuration).
I think that this error is related to the statement "The parameter name should be a provider invariant name as registered in machine.config or app.config" in the database target configuration page however I am not certain how to correct the error. I have the mySQL DLL referenced in the application.
Following is my configuration:
Please let me know what I am doing incorrectly and how to change. I really appreciate help. This is really a cool app!
Thanks
Ray
try changing the dbProvider to this
dbProvider="MySql.Data.MySqlClient.MySqlConnection, MySql.Data"

The application is developed on VS 2015 Express. The same connection string is connected to my local system but on live environment, it is giving me error. Please help me out.
Error Message: ProviderIncompatibleException
Exception Type: System.Data.Entity.Core.ProviderIncompatibleException
Error Location : An error occurred accessing the database. This usually means that the connection to the database failed. Check that the connection string is correct and that the appropriate DbContext constructor is being used to specify it or find it in the application's config file. See http://go.microsoft.com/fwlink/?LinkId=386386 for information on DbContext and connections. See the inner exception for details of the failure.
Error Page Url: http://10.0.17.3:8081/
Usually, there's a different Oracle TNS_ADMIN location and wallet location for the live environment vs. the dev environment. You can set the wallet location in the .NET code or in sqlnet.ora. The TNS_ADMIN can be set in the code or as a Windows environment variable.
This error is fairly generic. If you can identify an inner exception or provider specific error code, it would be easier to identify the root cause of the problem.
I am trying to configure WSO2 CEP to store the events to database table.
I have created Event Stream/Receiver,
I would like publish the Stream on a External Database using Datasource.
i am getting the below error while I trying to create Datasource to mysql or oracle
for mysql datasource
ERROR: Error in creating external data source: com.mysql.jdbc.jdbc2.optional.MysqlXADataSource cannot be found by org.wso2.carbon.ndatasource.rdbms_4.4.1
for oracle datasource
ERROR: Error in creating external data source: oracle.jdbc.driver.OracleDriver cannot be found by org.wso2.carbon.ndatasource.rdbms_4.4.1
Can anyone help me fix this one.
Thanks
I suspect that this issue is due to the missing database drivers in {$HOME}/repsitory/components/lib folder. Can you please check if the relevant database drivers are placed in this directory? You can find the documentation regarding setting up MySql and Oracle databases with CEP, respectively at [1] and [2]. Hope this helps.

I am trying to connect to MySQL database using Delphi Xe5 and fire monkey mobile application.
I am using an TSQLConnection to connect to the database but i get an error DBX Error: Driver could not be properly initialized. Client library may be missing, not installed properly, of the wrong version, or the driver may be missing from the system path.
I have read the below articles of which none had a solution that worked.
Articles:
DBX Error: Driver could not be properly initialised
http://wiltonsoftware.com/posts/view/getting-embarcadero-dbexpress-mysql-working-dbx-error-driver-not-initialized
None of their solutions seem to work, i use delphi xe5 on Windows 64x.
I have tried downloading the zip file libmysql.dll and coppied into the following paths mentioned but to no avail.
C:\Users\Public\Documents\RAD Studio\12.0\Bpl
C:\Program Files (x86)\Embarcadero\RAD Studio\12.0\bin
Can anybody please assist me in understanding why i am not able to connect to my MySQL database?
Your error message
DBX Error: Driver could not be properly initialized. Client library may be missing,
not installed properly, of the wrong version, or the driver may be missing from the
system path.
is the standard generic one from DBX and just seems to mean "something went wrong somewhere". Error-reporting doesn't seem to be DBX's strong point; a couple of times recently I've had that error when the problem turned out to be quite different than it might lead you to expect. What's annoying about it is that I only found out because I happened to have "Break on exception" turned on in the IDE and could see that the initial exception came with quite different and more revealing info, but the DBX driver seems to re-raise with that text entirely replaced by its generic, info-free version, at least in the circumstances I ran into.
AS you've subsequently found out, a FireDAC connection may succeed in connecting where a DBX one fails, and even where it fails, its error messages are more specific than DBX's. It's a shame because I find FD more fidly to set up (like I always forget its SqlWait component and it doesn't tell me that I have until r/time). So, I'm not suggesting anyone should switch to FireDAC if they've already got DBX working on a given database, just that FD can be a useful diagnostic tool.
I am running Visual Studio 2010, and attempting to update my Entity Framework project using the Update Wizard. When I attempt to add a single table from the MySql database, the add tab will show the table that I am attempting to add, however when I click finish, I get the following error message.
Unable to generate the model because of the following exception: 'An error occurred while executing the command definition. See the inner exception for details.
Fatal error encountered during command execution.
Fatal error encountered attempting to read the resultset.
Reading from the stream has failed.
Attempted to read past the end of the stream.
I get the same error message if attempt to create the Entity Framework from scratch. In addition, Server Explorer shows that the connection is successful when I test it.
I have also contacted Host Gator who is hosting the database and they where not able to see any issues on their side.
The problem ended up being that our shared server, was not able to handle the Update Request from the Entity Connector Framework and was timing out. Once we moved our database over to a different server we no longer had an issue.
I have upgraded my server machine to use MySQL Connector 6.3.4 and in our website we also added Membership role provider.
When I run the website I am getting this error.
Configuration Error
Description: An error occurred during the processing of a configuration file required to service this request. Please review the specific error details below and modify your configuration file appropriately.
Parser Error Message: Unable to initialize provider. Missing or incorrect schema.
My sql server is version 5.0.90 community-net.
Is there any setting which have to be changes on server side while upgrading connector
This is tag in my web.config file.
Since when I run the website on local machine it will run successfully, but on server I am not able to run it and getting above error.
There is no mistake in connection string
What are server side setting which we to do while upgrading the connector....
thanks
I myself running into the same problem. I m using Mysql connector 6.3.0.0
So far I came across following suggestions when seaching on net:
1) Add "MySql.Data.dll" & "MySql.Web.dll" into your application "bin" folder.
2) Add reference to above to dlls in your application .
3) Add autogenerateschema="true" in your web.config file for required sections.
4) Check your Mysql connector version - make sure that the one that is in your bin folder is mentioned in your web.config file.
5) Check your connection string - make sure it is correct and connected successfully.
6) Check mysql membership related table structure.
7) Check schema version in "my_aspnet_schemaversion" table (e.g since you have upgraded to newer version I insist you should check this).
8) If the problem is on remote machine (e.g Production Server) you may wan to check this : http://www.reggieburnett.com/referencing-connectornet-on-a-remote-machine
I m sure you may gone through this list but I would like you to check schema version in "my_aspnet_schemaversion" table (e.g compare "version" field value of your local and remote table) since your upgrading to newer version.
BTW: I have checked this list for my problem but it did not help. I hope it may be of some help to you.
Edit:
Hi,
We are able to fix this error by following:
1) Deleted the tables for memberships in the db and had the mysql membership provider regenerate them
2) than set the Aministration.config file to trust the Mysql Membership Provider (e.g related to IIS admin)
Regards,
Gaurav
I had this same problem after checking all the things in Gaurav's post. It ended up being that the user account I was using in my connection string did not have necessary permissions to alter the db schema (I had autogenerateschema set to true). Once I changed my connection string to a user with more privileges (I used the 'root' user) then it updated the schema, and I changed the connection string back to the original user.
Always make sure that the Datasource is set to the real ip address and not localhost and check the passwords and usernames too. I am working with these clients and their ip address keeps changing and every time they do that, I get the same error
I know this is an old thread but maybe this will help someone. I was having this issue and realized that I was editing the wrong machine.config
At first I was editing on under C:\Windows\Microsoft.NET\Framework64....
Once I found the one for my .NET version under C:\Windows\Microsoft.NET\Framework.... and edited the correct spots, it worked fine following the instructions on MySQL's site.
