is filestream filegroup size considers in database size?
while calculating database size will it necessary to consider filestream filegroup size??
sp_spaceused stored procedure returns size of database but it consider only data and log files.
my question is : can we consider filestream filegroup size while calculating database size or is there any other way which already consider filestream filegroup size??

Insert batch limit in SQL server SP
Hi All,
I have SP which inserts 100000000 rows at an average. But We want to keep transaction as small.
We decided to use batch separator in SP. It should load 100000 rows in a transaction.

time out occurred while waiting for memory resources
Team,
I am have Microsoft SQL Server 2008 SP1( 10.0.2734.0) 64bit with application being SCCM 2007
I am getting below error in SQL error log ::
Error 8645: Severity 17, state 1
A time out occurred while waiting for memory resources to execute the query in resource pool ‘internal’. Re-run the query.
At first glance, i thought that it is issue of query not getting enough memory.
Searched on google but could not get way to resolve it or issue creating factor.

Database Log file size increasing
- My database size is 1.5 TB under 1.5 TB log file size is 200 GB ,
- We are taking the backup weekly full backup, daily differential backup and every 15 min log backup.
- Last 2 days onwards we are getting alerts your log file disk full like that.
- Here there is no chance to increasing the disk space.
Note: for that database LOG SHIPPING is going on.
We are trying shrinking the log file but no use.
The final option is truncate the log file, if we truncate the log file LOG SHIPPING working or not
If truncate the log file log shipping LSN break or not? LSN break how we shrink the log shipping with take the full backup. The database size is more.

Access Denied Error Trying to Restore Database
I have a database backup of a 2008R2 database sitting on Machine1. I want to restore it to Machine 2, which is SQL 2012. both machines are on the same domain. Below is my script but I am getting the error" The operating sytem returned the error '5(Access is denied,)' while attempting 'RestoreContainer: ValidateTargerForCreation on 'D:SQL\MSSQL11.MSSQLSERVER\MSSQL\Data'. This error is followed by File 'DBName" cannot be restored to 'D:SQL\MSSQL11.MSSQLSERVER\MSSQL\Data'. Use WITH MOVE to identify a valid location for the file.
RESTORE DATABASE DatabaseName FROM DISK = N'\\SQLSVR\FullBackups\DatabaseName\DatabaseName.bak' WITH FILE = 1, MOVE N'DatabaseName' TO N'D:\SQL\MSSQL11.MSSQLSERVER\MSSQL\DATA'; RESTORE DATABASE ISSPortal FROM DISK = N'\\SQLSVR\FullBackups\ISSPortal\ISSPortal.bak' WITH FILE = 1, MOVE N'ISSPortal' TO N'D:\SQL\MSSQL11.MSSQLSERVER\MSSQL\DATA' , MOVE N'ISSPortal_Log' TO N'D:\SQL\MSSQL11.MSSQLSERVER\MSSQL\DATA', REPLACE GO
If I run the second query then I get File 'D:SQL\MSSQL11.MSSQLSERVER\MSSQL\Data' is claimed by 'DatabaseName_Log' and 'DatabaseName' . The WITH MOVE clause can be used to relocate one or more files.
I have granted the database engine service access to the path where the backup lives on machine 1.

Performance Tuning of FileTables
I am executing a simple statement like one below...
DECLARE @path VARCHAR(max)
SET @path = '\\fileserver\filepath'
SELECT stream_id
FROM ReportFiles
WHERE file_stream.GetFileNamespacePath(1) = @path
AND is_archive = 1
AND is_directory = 0
When executed concurrently I see a a lot of blocking locks ( LCK_m_s ) while in trace file I see blocking locks in the below statement which I believe is a result of GetFileNamespacePath
with partial_path_name as( select ft.path_locator, ft.parent_path_locator, N'\' + convert(nvarchar(max), ft.name) as partial_path from [ReportFiles] as ft where path_locator = @path_locator union all select ft.path_locator, ft.parent_path_locator, N'\' + convert(nvarchar(max), ft.name) + ppn.partial_path from [ReportFiles] as ft join partial_path_name as ppn on ft.path_locator = ppn.parent_path_locator ) select @namespace_path = partial_path from partial_path_name where parent_path_locator is null
Since this is a standard MS function, I cannot do much, any suggestions?
Thanks

Error: Could not continue scan with nolock due to data movement, DBCC proccache will clear the probelm
SQL Server: 2008 R2 SP2
Before describing my problem, I have gone via the forum, there is no view or functions inside my stored procedure
When running a particular stored procedure inside crystal report, the error " Could not continue scan with nolock due to data movement" comes once every few weeks. After I clear the query cache plan, it works again for few weeks and the problem
comes again. During these few weeks, there is no restart or query plan clearing.
If I run the stored procedure inside SSMS, where the SQL statement is copied and pasted from SQL profiler during crystal report run, there is no error.
I discovered running in SSMS and crystal report generate 2 different query plans even I copied the SQL from SQL profiler, I have actually saved the query plans. Unfortunately, this forum does not accept attachments, or otherwise I will post my query plans here.
There is one thing I notice about the query plan is during nested loop operation, there is a warning "no join predicate". I don't use any views or UDF in the statement, nor did I use pre-1992 ANSI join syntax. However, I did use table variables.
My guess is whether this will cause " Could not continue scan with nolock due to data movement", after I clear the cache, I run crystal report again, and I look at the plan again, the "nested loop no join predicate" warning is gone.
Running this stored procedure took 1 second maximum, even when this error is popping up, it pop up within 1 second.
DBCC checkdb has been run
The same stored procedure running by crystal report in a SQL 2008 (non r2) live environment has no problems, so I am thinking this is R2 specific problems.
The "nested loop no join predicate" error SQL statment is below, no views, no udf, but table variables
INSERT @ChequeAccount
SELECT PS.PaySummaryID, PS.EmployeeID, PS.CostCentreID,
(PS.GrossPay + PS.LumpSumA + PS.LumpSumB + PS.LumpSumD+ PS.LumpSumE+ PS.ETP+ PS.PaymentsAfterTax - PS.DeductionsAfterTax - PS.Tax- PS.ETPTax + PS.TaxRebate) * -1 AS Amount,
CGLM.GLAccountID
FROM Pay_Summary PS JOIN Input_Sheet ISH ON PS.InputSheetID = ISH.InputSheetID AND ISH.PayrollID = @binPayrollID
AND PS.PaySummaryID NOT IN (SELECT PaySummaryID FROM @ChequeAccount)
JOIN Payroll P ON P.PayrollID = ISH.PayrollID AND P.EmployerID = @binEmployerID
JOIN CustomGLFixMapping CGLM ON CGLM.EmployerID = P.EmployerID AND CustomGLFixMappingNameID = 1 AND CGLM.CostCentreID IS NULL

Database level settings
Please advise database level settings for all our databases for following items:
Virtual Log File
Database file growth settings
- And suggest what are the best practices around these items that we need to follow for future new databases. What are different things to consider?
- And also what would we need to do before making these changes on current databases?
Thanks,

Process runs faster when executed independently, but runs slower when a parallel big process is running
Hi,
The issue is, a process, say "A" is running fine on certain days. On some days there are additional processes running on the server. When these additional processes are running, "Process A" suffers performance issue.
Interesting point is that, these additional processes were running since long time. But, earlier "Process A" was running fine even when these additional process were running. Suddenly from past 2 or 3 weeks there is performance issue in "Process A", when these additional process run.
Note: Nothing has been modified for the process A.
Process A is an SQL job which has SSIS Package and stored proc in different steps
When multiple parallel processes are running, SSIS Package step suffers around 40% increase in execution time, where as stored procs have only 15-20% increase in execution time
When Process A is executed while no other big processes are running, it's execution time is fine. From past few days, issue is only when, some other big parallel processes are running.
Currently below is my analysis:
- Since Process A is running fine when it is executed independently, I assume there is no issue in this process.
- Since issue occurs when some other big process is running, when Process A is running, I believe it is DiskIO issue. Will the issue be resolved if RAM size is increased?
- Is there any way to check if RAM is being fully utilized by the server
- Is there any other possibility why there is a sudden dip in performance when parallel processes are running.
- Is there any possibility of having issues in additional processes. Incase if it has some issues, does it impact "Process A"
Please let me know if you need any further information. Infact I am not able to diagnose what is the actual root cause for the performance issue in "Process A" as nothing has been modified.
Also it would be very much helpful, if I get any idea on different ways in reaching the actual root cause of this performance issue.
NOTE: This is a data warehouse

Connecting to a SQL Server Named Instance, from remote client, outside network
Hi All,
I have what I feel may be a newbie question.
I am trying to connect Visual Studio SQL Server Object Explorer to a named instance of SQL server. The instance is sitting on a VM in Azure, and there is a port endpoint set up. The external port X is mapped to 1433 on the VM hosting SQL.
I am getting this error when I try to connect in the following ways webname\instance,port webname,port\instance webname,port
The Azure server name is : serviceName.cloudapp.net
The Instance is: INSTANCE
And the port is the external port number: 1234
I feel like I am making the newbie mistake in how I am naming the connection info. I have a valid set of SQL credentials that I have check locally. They cannot connect when outside the network, through the port.
