One of my servers has developed a problem where it will restart during the restore of a SQL database.  I've tried multiple databases and multiple backup files and it still happens every time....sometimes as early as the selection of the database backup file and sometimes as far as 60% completion of the restore job.  There is no memory crash dump or information in the event log as to what caused it.  Has anyone experienced this problem with SQL restores?  Any suggestions on how to figure out what is going on?

We are running with Availability Groups in SQL2012 SP1 with a primary and a secondary replica that will allow access if you use application intent read only which we are not doing. We probably have some automatic polling by SCOM 2012 that throws the 978 message all the time causing a large SQL errorlog full of these messages and not much else.

is there a way to suppress these 978 messages?

Thanks

Hello,

We experienced the following error chain (extracted from the SQL Server logs) that ultimately caused our instance to restart and fail over one of our primary AGs, causing us unexpected (albeit brief) downtime.  We've never experienced (or though it was possible that) a CHECKDB could shut down the instance - does anyone have any ideas?

From the error logs (all spid 408):

The operating system returned error 665(The requested operation could not be completed due to a file system limitation) to SQL Server during a write at offset 0x0000034a90e000 in file 'redacted:\database.mdf:MSSQL_DBCC12'. Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.

Error: 3314, Severity: 17, State: 3. During undoing of a logged operation in database 'database', an error occurred at log record ID (742678:3728:21). Typically, the specific failure is logged previously as an error in the Windows Event Log service. Restore the database or file from a backup, or repair the database.

Error: 831, Severity: 20, State: 1. Unable to deallocate a kept page.

Error: 3449, Severity: 21, State: 1. SQL Server must shut down in order to recover a database (database ID 12). The database is either a user database that could not be shut down or a system database. Restart SQL Server. If the database fails to recover after another startup, repair or restore the database.

And about 2 minutes later, on spid 10... SQL Server was unable to close sessions and connections in a reasonable amount of time and is aborting "polite" shutdown.

It is worth noting we do not have a database with an id of 12 - I've assumed that is referring to the internal snapshot DBCC was using though I haven't been able to confirm/deny that yet.

Several databases had completed their CHECKDB without issue (including one large database which takes ~2 hours to complete).  The database which was being checked was under moderate load at the time, and was participating in an availability group as the primary replica, with synchronous commits going to a secondary.

We're running SQL2012 SP1 CU3 with hotfix KB2832017 (11.0.3350 x64 Enterprise).

When searching we found some references to the 'Kept Page' error though they all seemed to relate to 2005 and were fixed by a SP.  We also investigated the file system filter driver route (as per Jonathan's blog entry) but we don't have any filters present.

This is the first time we've had the issue after several weeks of very similar workload patterns during the CHECKDB, and we're out of ideas for investigation.

One thing we have decided to do is to reschedule the CHECKDB for the database to occur at a time when less updates are happening and pay the CPU price during business hours (when the database has almost no writes), which our servers have the capacity for.  We're hoping this prevents the situation happening but would like to gain a better understanding of what happened, and so far tests on development hardware (pushing write heavy workloads through a database while running a concurrent CHECKDB) haven't reproduced the issue, though we get IO bottlenecks on dev that don't exist in production.

Any thoughts, suggestions, or comments are welcome.

Kind Regards,

Tim

We get the below error while performing a distributed transaction on linked server. We have several linked servers configured in the source server and all of them succeed with the distributed transaction except on one.

We did all the basic troubleshooting and moreover the distributed transactions work fine if we use a remote server instead.

Need your expert guidance in resolving this issue

Hello

I found some strange issue.

My Server specification:

I have Windows Server 2012 as os in server. In that machine I had installed sql server 2012 standard edition.

RAM is 8 GB. & Processor Intel(R) zeon(R) CPU E5-2609

My Laptop specification:

WIndows 8 , 500 gb hard diisk 8 gb RAM.

Now Probem is,

I put my database in My server. Now I Run My Application on my laptop. I connect to server using LAN.

I try to access database put on server in my application.

It works fine. Performance is also good.

Now I put Database in my laptop. & I try to run My application in server. Connection Is done using LAN.

I try to access database which I put in my laptop. But this time application performance is very poor. It is working so slow. Database communication is very slow.

This Problem is not limited up to mine laptop.

I put Database on another server with same specification that is

I have Windows Server 2012 as os in server. In that machine I had installed sql server 2012 standard edition.

RAM is 8 GB. & Processor Intel(R) zeon(R) CPU E5-2609.

Lets name this server A.

another server has same specification . lets name it server B.

SO If I put database on server B & run My application in server A & try to access database from server B, then also connection is slow.

I use LAN for connection.

Same thing is done in reverse.

I put databse in server A & run my application in Server B & try to access database from Server B t

hen also performance is slow.

Performance only fast If I put Database in Server A & Run my application from my laptop or any other Computer then try to access database then performance is good.LAN is used for connection.

I am not getting why this strange issue occur?

Can any one tell me why this problem is happening? How to solve it? 

Thanking you in advance..

Hi,

 I am trying out SQL 2014 Hekaton with Create table statement having  Composite Primary key ( 2 columns).

I want to include something like

[Name, Number ] PRIMARY KEY NONCLUSTERED HASH WITH (BUCKET_COUNT = 1024)

in the create table statement. Is this possible ?

Hi,

I had created 4 secondary data files across different disks on the same Primary file group. These 4.ndf files were created uniformly with initial size of 350GB and autogrowth of 2GB as was  my existing.mdf file

After running Reindexing the secondary NDF files equally had data flow of 30GB each. The reindexing was not done on all the tables of the database and was done only on some selected 70tables. 

Now i want to know real time validation to check if the secondary data file is getting utilized effectively ,that is DATA getting into the database is getting into these newly created secondary data files.

Can someone give me any T-SQL or an interesting method to get the output that objects are using these secondary data files.

No table partitioning has been done and these .ndf files are not under new file groups ,they are just added along with the primary file group.

Env : SQL server2008R2 SP2

Hello,

I'm working with SQL Server 2008Sp3.

I have a database that was restored from a full backup WITH NO RECOVERY and it then was restored with Transaction log backup files - also WITH NO RECOVERY.

At the moment the database is in Restoring status.

Let's say that couple of hours after the last transaction log restoration I want to continue restore the new 2 hourly transaction logs that were created, and then restore it WITH RECOVERY.

How can I query the status of the database, so I will know what was the last Transaction log backup that was restored on that database?

The reason I'm asking that is because I would like to automate this in a script -

I want to create a daily full restoration of a database on a separate server with all the available Transaction log backups WITH NO RECOVERY, and then upon request (when it's necessary), I'll be able to execute another script that will restore the new Transaction log backups that were created since the end of the daily script + restore it WITH RECOVERY.

My question is regarding the second separate script - finding the rest of the needed Transaction log backups.

Thanks in advance,

Roni.

Configuration details:

Server: Microsoft Windows NT 6.1 (7601), Windows Server 2008 R2 Standard SP1
    Installed RAM: 4.00 GB
    This is a VMware VM.

Microsoft SQL Server Standard Edition (64-bit)
10.50.1600.1
SQL_Latin1_General_CP1_CI_AS
Min Memory: 0
Max Memory: 2000 MB

This instance is on the same server as a SQL Server 2005 instance (Min Memory:0, Max Memory: 2000 MB). The 2005 instance was quiet at the time of the error in the 2008 R2 instance. Neither IIS nor any other significant services is running on this server.

This 2008 R2 instance is running SSRS and contains the databases for an AppFabric instance that is running on a different server. The only databases in this instance are the two SSRS databases and the two AppFabric databases, all of which are in simple mode.

The AppFabricMonitoringStoreDb.mdf (E:) is 1.5 GB and its log (F:) is 470 MB. tempdb.mdf (C:) is 250 MB and templog (C:) is 25 MB. All are set to allow unlimited growth. All drives have at least 5 GB free.

I had a similar problem last weekend, when the Max Memory for the 2008 R2 instance was set to 1500 MB. I increased it to 2000 MB as an experiment, but that doesn't seem to have helped. Given that the VM is only allocated 4 GB, the two SQL instances can't each take 2 GB and leave the OS with nothing, so maybe I just need to allocate more RAM to this VM, but I have 4 other VMs exactly like it (same pair of SQL instances, same jobs) that haven't had any such memory issues and they are more heavily used than this one.

I would appreciate any ideas as to how to track this down and fix the source of this issue.

Thanks,
Mark

We've been using filestream storage for an app we've written in C#.net.  I have some questions:

1.  It looks like C# code retrieves filestream data from SQL then uses Windows IO to actually retrieve the file.  Is this the most secure?  We tried turning off Filestream for file I/O access so the only way you could get the data was through SQL but this produced an error.

2.  We changed the login we use for accessing SQL Server to use SQL authentication only.  Once we did that we lost the ability to access filestream data via C# - I assume because we no longer running with a domain account that had permissions on the folder.

3.  We found a white paper from MS that suggested SQL Server logins cannot be used to access Filestream data.  That seems to suggest the choice to enable filestream for file I/O access shouldn't be optional.

We are trying to produce an application that is as secure as it can be while being easy to manage by users with little or no SQL experience.  We may need HIPPA like ability to restrict data access.  We don't want anyone with the ability to browse folders to open up the files we've saved in filestream.  At the end of the day, maybe filestream isn't the best choice for our storage...
