I designed the AlwaysOn wrong, but every time we fail over from primary server to another server, my applications cannot connect because the sql logins cannot connect to their default databases. Once I run the command to link the login with the user in the default database then the users are able to connect. Did I do something wrong when designing AlwaysOn?

I am using alwayson on my SQL 2012 databases. I am using ola hallengren scripts for backing up databases. Full & diff db backups work fine, but the log is not getting backed up. The tran log backup job doesn't error out too. Trying to figure out what I may be missing?

Hi,
I've just installed a brand new instance of SQL on a new server. It's for our Helpdesk/Inventory software. All I needed to install was the DB Components and the Tools (primarily for Management Studio). I did not install SQL as a default instance, but called it TRACKIT8 (software using this instance). I have subsequently installs SP2 before trying to connect to the DB.
I am unable to conect to the DB Engine via Management Studio. In the Server name: field, there is a blank space, so I try to browse for a server, but I get nothing. I try to manually type the name of the server (NIASSQL2, localhost etc) into the field, but I cannot connect to the engine at all. I can see the services for the Server and Server Agent have started in the SQL Server Configuration Manager and I am able to change certain field in the properties of the Server and Agent (change the path of the error logs).
Is there something I am supposed to configure before I try to connect via the Management Studio? I am looking to change the paths of the Data Files, as I don't want them on my C: partition. Plus I have other instances I want to create and install. Any help would be greatly appreciated.
Cheers.

Hi! I have a little problem and I need your help.
I have recently installed SQL Server 2005 Developer Edition. I did not install all the features, just the Database engine and Analysis Services. I also updated everything with SQL Server SP2.
So far, so good. But when I tried to connect to the Database Engine, I get a little window with the following message:
"Cannot connect to Valentin-PC (server name)."
"Login failed for user - User Name - ( Microsoft SQL Server, Error: 18456 )".
I have tried just about everything, but to no avail. What is strange is the fact that I can connect to the other server type that I have installed (Analysis Services). No connection problems there.
Can anyone help?
Mucho gracias!

I just installed SQL server Enterprise 2005 and connected database engine in SQL server management studio, but it is blank space when choose 'browse for more' at server name field. What's reason to cause this problem?
Questions for this problem:
1. Do I need to open the TCP port 1433 in firewall by hand for connect database engine?
2. I can€™t find the sqlbrowser.exe in SQL server/90/ folder, can I copy this file into it.
3. The SQL server mobile is work; I can connect the new created database. What€™s different to use SQL server mobile and database engine?
4. I got five discs from Microsoft; I have installed DVD server application and pack 2. Do I need to install the library?
Thanks for any help.

Hi, I have looked and loked for the answer to this question and made no progress. I want to install MSDE on one of our servers, however, when I went to install it, I found that there was another MSDE already installed and running (it was an agent running with our backup software Veritas). Is it alright to create another database and have 2 running simultaneous on the same data engine? Is there any type of limitations that I sould know about - such as number of allowed accesses at one time? Any help is greatly appreicated.

In our production we have a database by name MyDb.The application team wanted another database by the name MyDbOld which contains the data of Mydb 1 month old. So I created a database MyDbOld in other instance(test) and restored MyDbOld from the one month backup of MyDb in production server. In test instance I backed MyDbOld as MyDbOld.bak...
In the production instance I created a new DB by the name MyDbOld and restored the MyDbOld in the production from the backup of MyDbold.bak in the test instance. Now I have 2 databases in the production instance ie MyDb and 2)MyDbOld. However I find the logical names of both the databases to be the same although the database name and the physical file name to be different.My questions are-:
1) Does it in any manner affect the integrity of the 2 databases if the 2 databases are in the same instance and have the same logical name?
2) Would the dml or data retrieval operations in the 2 databases have any conflict in any manner what so ever?
3) Having a unique database name, and unique file names for the physical files for any database in an instance what is the purpose and significance of additionally having a logical name for a database?
4) Which I could restore a database from the backup of another database in the same instance and at the same time change the logical and physical name of the files to correspond to the new database.

Plz also inform me about the restriction imposed in connectivity by any of the window operating system such as that win 98 wont work or work!
There is no firewall involved. The two computers are in the same room and connected directly to the internet.
Even the ping is not going to either computer.

I am working (or trying to work) in Management Studio. I have one database that I use on my one and only machine. ( I am not using any of the default databases.) I have several queries saved as files, which I open as needed. Every time I open a file I get that VERY ANOYING Connect to Database Engine dialog box. OK, it's no big thing. I don't use Server Authentication so all I have to do is hit enter and I get connected. But why should I even have to hit enter once after I'm already connected?
How can I MAKE IT STOP?
Thanks,
Gregory

Hello,
I have installed SQL Server 2005 in my PC and during the installation I
have created a predefined instance (I have used Windows autentication).
I could use correctly SQL Server till some days ago, when I changed the
password of my PC login profile.
Now, when I open SQL Server, if I click on the "Connect" button,
the following error message appears (I translate it from italian version)
Unable to connect to "CARLO"
Further information:
An error has occurred while you were trying to establish a connection to
the server. When you connect to SQL Server 2005, this error can be generated
because SQL Server doesn't allow remote connections under the predefined
settings. (provider: Provider Named Pipes, error: 40 - Unable to open a
connection to SQL Server) (Micorsoft SQL Server, error:2)
I'm sure that the error raises because I have changed my PC access
password (the program worked correctly before), but in the "Connect to
Server" window the user name and the password text boxes are disabled, so
I can't insert the new password...
Can you suggest what have I to do?
Thank you very much

We have 3x instances of SQL Server 2012 installed on a single remote server - there's the default MSSQLSERVER instance, then INSTANCE01 and INSTANCE02. I can remotely connect to the default MSSQLSERVER instance through SSMS, but I cannot connect to either of the additional named instances (INSTANCE01 or INSTANCE02).Â
For example, if I try to connect to "sql.domain.com", I can successfully access the default instance on the remote server. If I try to connect to "sql.domain.comINSTANCE01", I get an error stating
"A network-related or instance-specific error occurred while establishing a connection to SQL Server".
However - if I try to connect to "sql.domain.comINSTANCE01, 49301" (where 49301 is the TCP Port for the TCP/IP Protocol for this SQL Server instance), I am able to successfully connect.
This leads me to think that there's a communication issue with the SQL Server Browser service running on the remote SQL Server and my workstation.Â
The following items have been verified:
SQL Server Browser is running on the remote SQL ServerWindows Firewall has been disabled on the SQL ServerTCP Ports 1433, 1434, 1954, and 49301 have been opened up on the remote destination's firewallUDP Port 1434 has been opened up on the remote destination's firewall.

OK.
I'm using Microsoft SQL Server 2005 Developer Edition and I installed it under "Local System" on Microsoft Windows Vista Ultimate.
I understand that there are issues of course that occur with this, however I can't seem to understand why what I'm doing isn't working. I'm not using this on any server, just to test out ASP.NET 2.0 applications - nothing more.
I'm getting this error:

I've installed this via a mixed authentication (as suggested by www.wrox.com).
I tried enabling the TCP/IP and named pipe connections, just as previous people have done, but it hasn't worked. Nor has enabling the SQL Browser.
I'm really at a loss on what to do.

Is there any description on what the Remember Password check box on this dialog box does? As far as I can tell, it doesn't do anything. Every time I open an item from a project, or create a new Query, I get asked for the password, no matter how many times I have given it for the Server before.
It looks so useful, but is frustrating not knowing how to use it.
Thanks,

I work in an environment where everyone is there own server. I can connect to a collegeau's SQL Server by using the Windows Authentication method in the Database Engine but if I try to connect to the Reporting Services Engine it says that I am not allowed to connect due to permission violations. How do I get adequate permissions to do so? I have all of the components for Reporting Services installed and I am actively using it.

We have recently migrated quite a databases around 20 from SQL 2000 and 2005 to SQL server 2008R2.
I am using Ola's script for index maintenance for those with compatibility level above 80 as i heard it supports that way.
Hence separated in 2 way job where for those with compatibility level 80, we are running job with below query on each database with 80 as compared
USE ABC
GO
EXEC sp_MSforeachtable @command1="print '?' DBCC DBREINDEX ('?', ' ', 80)"
GO
EXEC sp_updatestats
GO
I am not sure if this is the only way in for those databases, because we are seeing the database getting because of that somewhere using above query.( seems log file filling very rapidly).
But above is not the case with those databases , with compatibility 90 and above.

Hi, If you have 2 databases with the exact same table columns, and in the first database in a table column the indentidy seed starts at 1 and finishes at 32,000 can you attatch a second database so that the indentity starts at 32,001and carries on. What happens if you create a site and run out of disk space and need to attach another database which is located on another server??? I am really confused about this.Hope someone can give some links to some articles about this as I can't find any information about it.How can this be done? Thanks
