No Database Instance in nopcommerce 3.90 - nopcommerce-3.90

I am facing error in nopcommerce 3.90 when run the project at that also at sometimes it is working good but after sometimes it shows the error of "no database instance". I am surprised it shows this type of error. Because the normal thing I have done to run the nopcommerce project.
I have done these things:
set the setting file by installation of nopcommerce.
delete the bin folder of nopcommerce.
clean the solution and rebuild it.
But still facing the same issues.

"no database instance" this type of error occures when the Nopcommerce is not able to connect with the database. If you have created database locally then try to find SQL service and restart the service. But if you are having database being hosted on any other server then check you network connection.

There are some of summery solution that i have mention as below
=> Since i had moved a live cart to a test server, the settings in the database for that cart had force ssl and also force www before any url. Also under Store settings i still had the domain info for that site which was now difrent in the test server. Once i noticed this and updated the database it all started working.
=>
You try change settings.txt file:
DataConnectionString: Data Source=localhost/IP;Initial Catalog=DBName;Integrated Security=False;Persist Security Info=False;User ID=DBUser;Password=DBPass;MultipleActiveResultSets=True
=>
In my case I need config application pool for nopcomerce
my connection string
DataProvider: sqlserver
DataConnectionString: Data Source=.;Initial Catalog=nopcommerce370;Integrated Security=True;Persist Security Info=False
I need set Application Pool Identity to user has access right to db
Check the image to details.
=> Check also db permission.
=> try with
Data Source=9X.2XX.7X.XX\"yoursqlservenameinstance"
or
Data Source="yournamemachine"
or
Data Source="yournamemachine"\"yoursqlservenameinstance"

You can do some thing like
Check setting file on App_data existing or not
Check connectionstring is correct or not
Check your SQL server working or stop by try connect
Clear cache your browser

Try This ``
Right click on the downloaded file (nopCommerce_3.40_Source.rar) ->select properties -> press "Unblock".
and
and change connection string in Settings.txt file.

Can not connect to IBM content navigator web administration

When I tried to connect to the navigator web administration, I receive a message "The desktop can not be opened" and It require defining a desktop ID.
http://imgur.com/JNKelPy
How to fix this problem or define a desktop ID?
I can't remember if after an installation default desktop is admin or if you have to set it manually. Is your URL with ?desktop=admin at the end working (https://ecm.filenet.com:9443/navigator/?desktop=admin)? If it does, create a desktop and set it as default. If it doesn't, you should take a look at the WAS log (SystemOut.log) to see what the error is.
After successful deployment of IBM Content Navigator, the admin desktop is automatically created. It is considered the default desktop until another is created with a valid repository. If you have issues, you should put in the full admin console address:
http://www.ICNADDRESS.com:9080/navigator/?desktop=admin
The desktop selection code at the end (?desktop=) can be used to specifically go to any desktop in the configuration, but the code treats the admin console address shown above as "special" for authentication and processes it slightly differently. I've had normal desktop configurations (especially after upgrades from 2.0.1 & 2.0.2) have issues for administrative users.
IBM Content Navigator uses DB tables for it's configuration data. You can find the desktop related info in a table named CONFIGMGMT including admin desktop.
There are server possibilities for the error that you are getting
CONFIGMGMT table has corrupted data regarding admin desktop.
CONFIGMGMT table has been deleted.
The DB table is accessed by Content Navigator via data source created in your application server and the connection to the underlying database is not made due to authentication issues(very common due to password change policies).

Magento - How do i transfer from local to live`?

I know this question has been ask quite a few times, but nothing seems to be working for me...
I really need help. I have made my entire website on my localhost, but hos do i get it up and running live? I've tried everything :( I've copied all of my files onto the live server and looked at endless tutorials, but nothings working. Can you maybe do a video about this or tell med what to do? I really don't want to start ALL OVER on creating all the pages and static blocks and so on.
You have to just change the url in database table. Run the query
SELECT *
FROM `core_config_data`
WHERE `value` LIKE 'http://%';
and change the url from localhost to live server url. Hopefully that'll work. Thanks
I guess that you already created many blocks, cms pages and did a lot customizations in backend in local system. You have to do next:
Copy your magento code completely to server.
On server, delete app/etc/local.xml
Create empty mysql database on the server
Backup your local database
Import that local database into database on server (which you created in step 3.)
Run magento site via browser
because you deleted local.xml file, magento will start installing process and ask you for params for db in server (here, enter data which you used for creation db in step 3, like db nambe, username, password,..). And that's it. Magento will make connection with that db and you will have everything you had in local.
One more thing which I forgot:
you have to change in database on field (you will change this on live database after importing local database, that means after step 5). There should be table core_config_data. Do search in that table, and wherever you find you local url like:
http://localhost/magento/
or something like that, you should change to your real domain, for example to:
http://my-magento-domain.com/

CodeIgniter error - unable to connect to database using the provided settings

I have a CodeIgniter setup that has been running fine for the past 2 months and recently I keep getting:
CodeIgniter error- unable to connect to database using the provided settings
I've recently added a new domain that has a landing page for the database login (zPanel), but I don't see how that could have caused a problem--maybe the page keeps getting directory attacked or something, but I'm not sure.
Is there a way to check if this is the problem through logs? I'm at dead ends with this problem, as when I restart the server (DigitalOcean) it works fine again.
Really not sure. If anyone else has had a similar problem, I'd love to hear your solution.
Thanks.
I think your mysql is going down so Codeigniter can't connect to your database settings.
Please login to SSH and check processes by "TOP" comment. See what is using resources ram or cpu.
And check your mysql conf settings, be sure that everything written if its empty it will cause alot of problems.

MVC 3 - Writing to productive Database on SQL Server 2005 does not work (testing on local SQL Server 2008 does work)

I'm a bit confused. I built my MVC 3 project which works fine in my development environment and the integrated IIS in Visual Studio 2010.
After deploying it to an IIS 7 it seemed to work, too. Reading does. But when I try to change some database values, it simply does not do anything. It seems to work, but after a reload of the changed values, they aren't changed at all.
Development database is on a local MS SQL Server 2008 and production on a remote Server with SQL Server 2005 (in this case, but the version will differ later on). Is there any difference? The user in the connection string has full rights, since changing works via Management Studio.
The connection string looks like this:
<add name="MyDBEntities"
connectionString="metadata=
res://*/Models.MyDB.csdl|
res://*/Models.MyDB.ssdl|
res://*/Models.MyDB.msl;
provider=System.Data.SqlClient;
provider connection string="
data source=10.90.0.88;
initial catalog=MyDB;
persist security info=True;
user id=foo;
password=bar;
multipleactiveresultsets=True;
App=EntityFramework""
providerName="System.Data.EntityClient" />
Thanks in advance.
PS: I build the project with Entity Framework 4.1 which is installed on the server. Well, reading does work though...
I would suggest ensuring that you have the correct connection details. The easiest way I can think of would be :
Create a new text file ( f.e. connection.txt )
Rename '.txt' to '.udl'
Double-click the created connection.udl file
Provide all the required connection details, hit 'Test connection' button
If it works, hit 'OK' button, open the file with Notepad - connection string will be inside of your connection.udl file. If it doesn't work - you need to find out proper server details ( check instance name, port number, if your user has the correct permissions )

Problems with Database Deployment using VS2010 (Package/Publish SQL tab)

Background:
I am using the deployment tools in Visual Studio 2010.
I right clicked my project and selected Package/Publish settings. Put all my settings in there ...
I am then using "web deploy" to tranfer the files to my remote server running a remote agent service and this is working fine. The transforms i have on my Web.Release.config do their thing and the server can access the database I created manually.
Problem:
My next step was to get the Database Deployment working too.
I went into the Package / Publish SQL tab and entered my Connection string for the destination database.
(Data Source=MyDBServer;Initial Catalog=Database2;User ID=User;Password=pass)
This database is empty ready to accept the import.
I also enter in the connection string for the source database. This lives on the same server.
(Data Source=MyDBServer;Initial Catalog=Database;User ID=User;Password=pass)
Database Scripting options are set to Schema and Data (changing this makes no difference) and the database scripts are set to [Auto Generated Schema and Data]
When i deploy this now, i get the error:
Error 4 Web deployment task
failed.((09/06/2010 16:41:51) An error
occurred when the request was
processed on the remote computer.)
(09/06/2010 16:41:51) An error
occurred when the request was
processed on the remote computer. The
entry type 'Unknown' was not expected
at this time. The serialization stream
may be corrupted.
Additional Info:
I can successfully create a package with no problems. I looked at the contents in the zip and can see the SQL is generated fine (so no problems connecting to the database). I can then copy this SQL and run it as a new query on the new database and the tables and data are created fine.
I can not seem to work out where this is going wrong, i googled the error and there are no entries on the whole internet. Anyone have any ideas?
Addendum:
To get some further idea of what might be going on, i sent the package across to the server and imported it using IIS. It told me i needed SQL Server Management Objects. So I installed that.
Next attempt it told me my user did not have permission to create the database, I thought excellent this must be the problem. :Granted access - Re-run. Passed!
So i deleted all the tables and went back to VS2010 clicked publish and i get the same error. :(
Sorted it!
Thank goodness, i was totally out of ideas when i went back to a video by hanselman. He mentioned that the Web Deployment Agent can have permissions. I went in had a look and there was a tab in it's properties called log on.
I entered the detials of an account with a decent level of access and clicked okay.
I then restarted the service as requested to enable the changes.
I then went back to VS 2010 and clicked Publish Web.
Music to my eyes, i see the words "Publish succeeded", I check the database and the tables are there. Excellent!
I think i scared the office by getting a little over excited, if you get this problem and this solution fixes it for you, try to hold in the temptation to shout out "YES!, yes, get in!" while laughing maniacally or people will think you're weird like me.
