SQL 2014 Linked Servers with Availability Groups
Good afternoon All. Hope your well. We have SQL 2014 Availability group setup over multiple Subnets.
So basically Instance A(In Primary DC), and Instance B (Secondary Replica, in secondary DC), with AG1 (Availability Group)
When I connect to the instance Directly (using SQL management Studio), and attempt to create a linked Server to another SQL 2014 instance (Instance D, Both use the same Service Account), I am able to successfully connect, and run query on the Linked Server. However when I connect to the Availability group, I attempt to open the linked server (to Instance D) and receive the following error:
Login Failed for User 'NT Authority\Anonymous Logon'
This above only happens when I connect to the AG1, and not the instances directly. I have given the Service account permissions to Read and Write its own SPNs (Using ADSI Edit). Researching this people have stated to add the Availability Group Name as an SPN to the Service account;
Setspn -A MSSQLSVC\AG1.mydomain:1433 mydomain\ServiceAccount
However, Im a little unsure at this stage, should the port in the above command reflect what the AG1 endpoint ports are? As I have done that (as well as trying port 1433), and unfortunately the error still happens. Your assistance would be appreciated,
kind regards,

Maintenance of clustered indexes
Hi,
There has been an overnight job running here for a number of years which rebuilds the non clustered indexes in a large database. I changed it yesterday to either rebuild, reorganize or ignore based on the fragmentation in sys.dm_db_index_physical_stats.
This job specifically ignores clustered indexes which puzzles me. Non of the original authors are here any more and I wondered why this decision would have been taken. Any ideas why they would ignore clustered indexes?
Another question, there are a lot of heaps in the database which are also quite big (200,000+ rows). I've looked at a number of these and there does not appear to be any natural key I could use as the PK. Should I just add an identity column and make it the PK?
Thanks

tempdb + delete query
Hi everybody,
I work for a new customer. in his SSIS package he launches several SQL delete commands on huge tables.
Sometimes he gets such an error message Could not allocate space for object 'dbo.SORT temporary run storage...
Does the DELETE queries use tempdb and how?
Thanks
Pete

SQL 2005 database to open SQL 2008 database
hi
Need help. I have this question.
I have this database created in SQL Server 2008. But my developers only have SQL 2005. They are able to open this database in SQL 2005 using SP4(not with any other SP's). Is this method is correct and can they write all INSERT/DELETE/UPDATE/SELCT& create SP. Will it make an issue to SQL Server 2008 database as it is created in SQL 2008.
And if it is correct, is it mentioned in any of the MS documents. Thanks.
Regards

Where is Adventureworks or Northwind for SQL 2008 Express?
Hi, I have a server with SQL Server 2008 Express installed. I downloaded AdventureWorks2008R2-Full Database Backup.bak (I know it's not R2, but that's what I found on CodePlex), and got:
Restore failed for Server 'server\instance'. (Microsoft.SqlServer.SmoExtended)
...
ADDITIONAL INFORMATION:
System.Data.SqlClient.SqlError: The database was backed up on a server running version 10.50.2500. That version is incompatible with this server, which is running version 10.00.2531. Either restore the database on a server that supports the backup, or use a

Index Deadlocks
I am seeing a lot of deadlocks on a single table. There are two update statements that run frequently causing the problems. The table has a unique, clustered index on ID and a non-unique, non-clustered index on StatusDetailsID.
The winning statement is:
Update Messages set StatusDetailsID = @1 where ID = @2
The losing statement looks like:
Update Messages set StatusDetailsID = @2 Where StatusDetailsID <> @1 and DirectionID = @3
The winner has an X lock on the PK index on ID and wants an X lock on the StatusDetailsID index.
The loser has an U lock on the StatusDetailsID index and wants an U lock on the PK index.
I understand why this is happening, but am not sure how to avoid it. Most deadlock information deals with selects. The best I could come up with so far is to change the losing statement to load the IDs into a temp table and join the temp table to update based on IDs. I'm hoping for something better.
All ideas and suggestions appreciated.

Rename SA account
Hi All,
I am sure many would have needed to do this (DISABLE/RENAME SA as per some audit requirement)
By default, all system DBs are owned by SA. I am going to rename the SA account. After this, I know the owner of the system DBs does change to the new "renamed" user.
Is there any risk seen in doing this? I will be changing job owners from SA to SQL agent service account before renaming SA login.
note: I am aware of this known issue in upgrading sql server (http://support.microsoft.com/kb/968829/en-us)
thanks in advance...

Modellog.log file being moved with inapproprite name. Startup is now failing.
I ran an alter database command to move to model database to a new location. This was a DISA STIG security requirement. It is something I have done dozens or times successfully, but yesterday I went brain dead.
ALTER DATABASE Model MODIFY FILE ( NAME = modellog , FILENAME = 'C:\dir\modellog. log')
I should have proofed better, but I just plain missed it.
Notice the embedded space between '.' and log. Even though the file has been copied to the correct database it is still called modellog.log not modellog. log as expected by the startup process.
Is there any way to change the name the statup process is searching for? or is there a way to rename the file so it does contain an embedded space after the '.' ? I tried using and rename command without luck.
Thoughts?
Just my thoughts tomh

Connection attempts to an 'offline' database
Is there a way to determine whether anyone is trying to connect to an "offline" database in SQL Server 2008 R2 Standard Edition? We had to take some of the old databases to offline mode because of space issues, they are mostly not in use and I just want to run a process for an week or so just to confirm. Thanks!
