Database context does not exist or is invalid wincc что делать
SQL Server does not exist or access denied
We are currently migrating servers (2005 to 2008) and our host backed up the SQL database and transferred it to the new server.
I have transferred the website files and changed the IP address in the connection string and the global.asa file.
So technically speaking we have a mirror image on the new server, but when I try to launch a page that connects to the SQL I get the following error.

Check your TCP/IP Port is enabled or not
— Open SQL Server Configuration Manager from start program.
— Expand SQL Server Network Configuration
— Click on Protocols for XXXX
— Right Click on TCP/IP and open properties
— Enable TCP/IP
— In IP Address Tab, Set Port 1433 in the last option (IPAll)
The error message in this case is very likely correct. First, verify that the network path from you to the new server works and you can connect with the specified userid/pwd.
1) Open Management Studio and attempt to connect to the SQL Server instance by ip address. (By the way, you will probably need to use a SQL Server userid/pwd if you aren’t already since you’re on an Internet host and there is very likely no AD context for Windows auth.)
2) If you can indeed connect to the instance and your database using Management Studio then you’ve probably missed a connection string somewhere. Try to maintain only 1 location for said connection string, usually in a config file. Examine the error line reported in detail to discover which connectionstring is being used and to verify that it reflects the new server ip.
With misconfigured IP in SQL TCP/IP config does let you:
This happens when the server is cloned from another SQL server which carries the SQL IP config from the primary server as residue.
But client applications fail to connect using connection strings though using the server name with the following message:
Do the following to verify on the SQL Server:
I experienced this issue as well when setting up an installation on a new computer.
The connection problem I experienced was due to a firewall setting on the server that hosts MSSQL. The setting gave individual IP addresses access to it which ‘works’ in our environment since IP addresses are described by our administrator as ‘sticky’. Once the Firewall access was granted to my new machine’s IP address, the PHP odbc_connect(. ) statement I was running in my local WAMP setup completed immediately.
As with many problems, there is probably more than one way to run into them, but I wanted to be as explicit as possible about how I experienced it.
This probably would have been a little more clear if I had my own installation of MSSQL management studio on my PC but I do not.
Of the Inbound rules on the server housing MSSQL, I found a rule referring to the MSSQL instance and sure enough found the IP address of my old machine there underneath the properties tab «Scope» as a «Remote IP address». Here’s to hoping I remember this whenever I get my next machine! (The decommissioned PC’s IP has been removed)
@Darren, if you could leave a comment under the answer you accepted, it might be nice to know which of @Tahbaza’s suggestions led you to your resolution.

This is my first run after upgrading to 3.0. Throws error:
Variable «ea» does not exist.
composer:
«easycorp/easyadmin-bundle»: «3.0.x-dev»
I don’t have any yaml config files.
The text was updated successfully, but these errors were encountered:

Yes. The template doesn’t know what is ea is.
featuriz commented Apr 29, 2020
As per doc: https://symfony.com/doc/master/bundles/EasyAdminBundle/dashboards.html#admin-context
I’m new to this area of knowledge in symfony. Here in this doc they mentioned This context object is automatically injected in every template as a variable called ea
But this is not working.

Problem not solved with your info. I think the problem with my current project. So now going to create a new test project. Will update soon with that info.
Maybe my current project may have some errors.
featuriz commented May 2, 2020
On a fresh symfony install it worked.
I had an error while installing easyadmin.
The steps I done is.

I’m reopening because I want to look into this more in detail.

@javiereguiluz let me try to clarify non technically what brought this up in my case.
For me the «weird» part during my migration test was that i am used to extend the default EA2 layout/login template without taking care of anything else related to EA.
The Dashboard defined in the yaml config is not only the default but the only one.
And well, I got very confused that the old login template (and others) still exist and are documented, but are actually EA2 based and not useable/compatible at all. The moment i realised that I was already kind of debugging.
Don’t get me wrong, I can’t wait to update soon. Really like the new concept for EA3!
