I've got this question. Yesterday I was working in my SSIS project without any problem. In one of the task I have created a connection to one Oracle database. Everything was working perfect. Just to clarify, the project is hosted in a PC that is never switch off because there are some scheduled tasks that run very late at night.
But today, when I tried to run the package again I've get the following message:
Connection Management 'name' is working off line.
I tried to test the connection again but I could get any answer from the Oracle database. However from other PC's there is no problem with this connection.
What could be happening? or, what else is necessary to do in order to keep the connection working?
Right click on the connection manager and uncheck the option of "Work offline" or something of that sort.

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.

I have a CLR Project that I'm trying to publish using Visual Studio. I had to change the project to a SQL Data Tools project, and now it's not publishing. Each time I try, I get a timeout error. When I take it step-by-step, I find this line of code hangs on my server.
IF EXISTS (
SELECT 1
FROM [master].[dbo].[sysdatabases]
WHERE [name] = N'fwDrawings')
BEGIN
ALTER DATABASE [fwDrawings]
SET READ_COMMITTED_SNAPSHOT OFF;
END
Basically, I know it's trying to force the server into single user mode when I try to publish this up. It's just to my staging server and not to a production server, but this is still a problem. I can't keep kicking everyone off the server and try and switch it to single user mode every time I want to update the CLR while I'm testing it's functionality. And I don't want to wait for a maintenance cycle or down-time to promote it up to production. Is there a way around this?
Presumably you have READ_COMMITTED_SNAPSHOT turned on for your database.
If this is the case, you need to change your Database project settings to match. Check "Read committed snapshot" transaction isolation, within the Operational tab in Database Settings for the project.
For me, this prevented the publish timing out, i.e. I can now publish successfully.
For a safer way to deploy to a server that's in use, try using a schema comparison instead.
I'm setting up a new website and the site uses asp.net membership. This was working fine but today when I try and log in or do anything such as add a new user/role in the asp.net configuration wizard I get:
Warning: Fatal error 9001 occurred at Jul 30 2012 7:52PM. Note the error and time, and contact your system administrator.
Searching online, it seems to suggest that the logs are full, but I'm advised by the website host that there is ample free space, so I dont really know what to try next.
Has anyone come accross this before and if so, how did you manage to resolve it?
Thanks
I have had this problem recently too and after mountains of research it appears to be common when a database is set to AUTO CLOSE. I set all the databases to AUTO CLOSE = FALSE. This started with one database then went over to two and the next it was on all of them. I simply restarted the SQL Server Instance Service instead of restoring databases. Another way to fix the symptom is to take the problematic database offline and bring it back online again.
As it turns out this was a database issue. I couldn't even create a new table or drop a table and ultimately had to get the database restored, which solved everything.
Hi I have been battling with this issue all day. I have a vs2010 load test which consists of three scenarios which are composed of three different web performance tests.
Each of the web performance tests select urls from a database which is configured correctly and runs locally. However when the load test is run remotely it fails with the error:
Could not run load test 'Load Test' on agent 'AGENTSERVER'. Could not open the database 'URLSDB' requested by the login. login failed for useraccount
In an attempt to get this working the agents and controller are set to run under a domain admin account, I can login to the database through Management Studio. I've checked the connection string and can run the test locally but not remotely. Does anyone have any ideas? My next step is to set the connection string to the UrlsDB to use SQL Authentication
Finally managed to resolve it at 01:20AM. When checking the datasources of three individual tests which made up the mixes in the scenario, I found that the UI was showing that once one had been updated all three updated the connection string so that is why I was baffled as to why I was getting these errors, plus the error doesn't indicate which connection was having the issue.
So to eliminate the tests as being the issue I removed the datasource from each test and created individually named brand new datasources all till effectively pointing to the same sql server and the same database. Then I ran the tests and all performed correctly, finally!!
So the core issue was the connection strings in the underlying tests were incorrect. Will be testing the UI further to check if I was just my own error or there may actually be a bug in the UI, if I find a bug I'll report it.
Thanks to those who took the time to try to help me solve it, gutted that the issue was so minor when it had me baffled for nearly 20 hours :/
The domain admin account you are running the test from cannot connect to the database server from the agent machine.
Log into the agent and debug the database connection from there.
Please be aware that a thread blocking call inside a web test, such as this may cause issues with your load test. I recommend that you load all test url's during the test instanciation if at all possible.
Essentially minimise the database calls to as few as possible.
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.
