Dump files show various SQL stmts at time of Stack Dump.  Different one each time boot server.  Sometimes get  error messages about failed to open, but not consistent.  EXCEPTION_ACCESS_VIOLATION seems consistent but nothing specific.  CPU stays at 100% most of time, unknown cause.  Trace shows no locks on objects....

5 snapshots from 5 different days of log file at "Stack Dump" error are below.

Hello All,

I have 34 jobs on my sql server production environment. Some of them run almost once every 10 mins. The issue is I am only able to hold only one entry in the jobhistory for any job (whether the schedule is a day, month, minute). How can I increase this to hold a history of upto one week.

The current history settings in the agent are

Maximum job history log size(in rows): 1000

Maximum job history rows per job: 100

Thanks for you help.

Hope I am on the correct forum for this:

• 4 GB RAM
• AMD OPTERON 2.10 GHZ processor
• SQL Server 2008
• 100 databases (some are not used). The DB's in total size are 9 GB. They have been in existence for about a year.
• 70 sites on IIS.
• 10 GB free of 100 GB hard drive (this is rather worrying but I think this is because there is no recycle bin present; I will have to resolve this).

• 8 GB RAM
• AMD OPTERON 2.20 GHZ processor.
• SQL SERVER 2008 R2
• 70 databases (some are not used).The DB's in total size are 7 GB); one is one GB, 4 others are 0.5 GB each.
• 40 sites on IIS
• 25 GB free of 100 GB

Hello,

On our nightly maintence backup of our SharePoint 2010 server, two databases fail with the following errors. Indicates that the error is disk space but that is not the issue. All other databases backup except for these two?

1.

Executing the query "BACKUP DATABASE [SharedServices1_UserProfile_fc126..." failed with the following error: "A nonrecoverable I/O error occurred on file "E:\\MSSQL10.MSSQLSERVER\\MSSQL\\Backup\\SharedServices1_UserProfile_fc12628a901646e1a26dfc4732ab09a7\\SharedServices1_UserProfile_fc12628a901646e1a26dfc4732ab09a7_backup_2012_12_04_210024_2481077.bak:" 112(There is not enough space on the disk.).

BACKUP DATABASE is terminating abnormally.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.

2.

Executing the query "BACKUP DATABASE [WSS_UsageApplication] TO  DISK = ..." failed with the following error: "A nonrecoverable I/O error occurred on file "E:\\MSSQL10.MSSQLSERVER\\MSSQL\\Backup\\WSS_UsageApplication\\WSS_UsageApplication_backup_2012_12_04_210024_2070905.bak:" 112(There is not enough space on the disk.).

The following is the DB Maintenance Plan and the configurations provided the production environment:

Reorganize data and index page (selected)
Change free space per page percentage to: 10% 
Remove unused space from database files
Shrink database when it grows beyong: 50 mb
Amount of free space to remain after shrink : 10% of the data space.
Schedule : Occurs every 1 week on Sunday 01 am

The above confguration done for few databases in the production env. The datafile and log files spread across Drive D and E.

When the job runs, it consumes a lot of space - which leads the Drive D and E - Space outage occurs.

The Drive D has 7 gb and E has 6 gd free space. The DB size is 24 gb.

Why this much of space 7 + 6 = 13 gb of space during the optimization job is running.

During this scenario all the other web application halt and lead to a critical state.

It error shows that "the xxxdb log is full and need to take the trn backup".

Then i have scheduled the log backup before this job starts.

Even then also the problem exists.

Techies, need your suggestion to resolve this issue. Please help. Thanks

Hi Techies,

How to check SIZE of the Index for a particuklar database in SQL Server 2000. Need a SQL Query.

MRVSFLY

Hi,

I have a machine running SQL Server 2008 R2 on Windows Server 2008 Enterprise R2 (64 bit).  The server has 30GB RAM, with SQL Server max memory set at 24GB and min memory at 0.  Whatever demands are placed on the server, total server memory does not rise further than 9GB, even though CPU and page life expectancy both appear to be suffering as a result. 

SQL Server is the only major process running on the server.  Neither task manager nor process explorer reveal any other major processes, but task manager shows 29.8 GB physical memory usage.

Is there anything further at the OS or SQL Server configuration level that I should do to prompt it to use more memory?

Any help greatly appreciated,

Ed.

SQL Server 2008 R2 - Windows 2008 R2.

I am little bit confused by resource governer. Is this tool used to limit the resources or increase the resources ?. I am trying to give an instance on the server at least 20% CPU and 100% max if it needs it so that other processes form other instances do not cause time out errors on this particular instance. Is this the best tool to use or should I go with CPU Affinity Masks ?

We also want to assign 20% CPU to a Analysis Services. Is this possible (Other than Windows Task Manager and Windows System Resource governer) ?

Thank you.

Hi All,

I have a SQL 2008 cluster running with 2 nodes, and what I have recently noticed is that a snapshot creation code has been failing. I checked the cluster dependency property on the SQL instance

and I noticed that the dependency wasn’t set on the backup drive, I took SQL offline, set the dependency and then brought it back online and yet the create snapshot code doesn’t work.

Please note that the drive is a mount point.

Any ideas please

	(NAME = [DBNAME], FILENAME = 'X:\BackupMount\Snapshot\DBNAME_Snapshot.ss')

Hi All,

In one transaction(Thread) i am performing one update and multiple deletes on a table,

From other transaction(Thread) i am firing select query on the above table before committing above transaction.

The lock on the above rows or table releasing and returning 0 rows.

Can you please tell me why and when this thing will happen?

Thanks,

Hi, I have a stored procedure on my sql server that uses a linked server to select data from an oracle database and inserts to a temp table on sql server.

When I create a job to exec the sp I get this error....

Access to the remote server is denied because the current security context is not trusted. [SQLSTATE 42000] (Error 15274).

When the stored procedure is executed in management studio there is no problem.

TIA

Hi Experts, I am facing an issue after killing a spid which was actually hanged in a job, job was calling a stored procedure to read the sql server log and to send it via email.

here is the stored procedure code

ALTER procedure [Error_log_Reader]
(@noofhours smallint)
As
Begin
set nocount on
Declare @errorlog table
(logdate datetime, Processinfo varchar(15), errormessage varchar(max))
declare @starttime datetime
declare @endtime datetime
set @starttime = (select  DATEADD(hh, -@noofhours, GETDATE()))
set @endtime = (select  GETDATE())
insert into @errorlog
EXEC master.dbo.xp_readerrorlog 0, 1, 'Not',null , @starttime, @endtime 
insert into @errorlog
EXEC master.dbo.xp_readerrorlog 0, 1, 'Error',null , @starttime, @endtime 
insert into @errorlog
EXEC master.dbo.xp_readerrorlog 0, 1, 'Failed',null , @starttime, @endtime 
--- checking whethere any error is there in the log
declare @errorcount smallint
set @errorcount  = 0
set @errorcount = (select COUNT(*) From @errorlog)
---- if there are errors, sending the email to dba
if @errorcount > 0 
begin
--- then it will send me the email----
end
End

It was working fine but today i got a CPU usage alert and i found that this job got hanged, i located the spid and killed but now it is in

waiting mode "lastwaittype" is msql_xp and the "waittime" is increasing in the sysprocesses view. Re-execution of kill process shows

transaction rollback in progress, estimated rollback completion 0%.

The instance is SQL SERVER 2005 SP1.

Please review the above code and if there is any bug in the code please identify. if there is any solution for getting rid of msql_xp wait without serive bouncing please share. Thanks

Hi Everyone,

I'm in the process of analyzing a sql 2008 database for performance reasons. I have discovered a significant number of DML query plans that seem to show a high operator cost for 'Clustered Index Update' as well for plans that have a 'Clustered Index Insert' operator. By high I mean the operator cost shows one for example of having an estimated cost of 0.030003 (912%). Is this something that I should be concerned about? I'm going to soon (hopefully this week) run 'SET STATISTICS PROFILE ON' to see if that helps explain what might be going on. This particular table's row count is approx 50K. The table has one clustered index on a uniqueidentifier (Random) and one unique non clustered index on a FK column which points to a table that has a row count of approx 260K. There is also a FK to another table with 24 million rows. Most other tables have a similar physical design (PK clustered on random uniqueidentifer surrogate column. FK to this other table with 24 million rows). The system is a OLTP system and is more read intensive than write intensive. About 5 users with write capability in the system at a time. About 10-15 users with read ability active at the same time. Some reports are written against this database.

The update statement does not attempt to update the clustered key column. It's possible it could update the non clustered key column though that typically never changes.

I could try to post the show query plan XML if needed if I can get it to fit into this thread.

Thank You.

I have a created a blocking alert.  It works, but I'm very fuzzy about the WMI properties.  I use the (WMI(property)) token to get the property values, but I am unsure of what I'm getting.  I would appreciate any advice on any of these questions.  Sorry about being so verbose. 

1) Are the WMI tokens textual representations of the values?  For example, the SPID value is listed as Sint32 in the documentation.  Is it actually an INT that I can use in T-SQL?  Or is it a string representation of the INT that must be quoted and converted to the type listed? 

2) Should I be using N'$(ESCAPE_SQUOTE(WMI(property)))' for all WMI properties I use? 

http://msdn.microsoft.com/en-US/library/ms180522(v=sql.90).aspx lists the inherited and event properties.  It appears to me that the inherited properties can relate to the event, but some are for the process handling the event.  For example, the DatabaseId is that in which the blocking exists.  However, the SPID value is always 8 which appears to be the process handling the event.  

3) Is there any documentation with detail other than a type for these properties?  Which should be ignored in general? 

I noticed that the inherited values for LoginSid and SessionLoginName are blank.  I don't know if I am getting them incorrectly or if they don't have any values in this case. 

4) Quoting a Uint8[] array?  Does this convert?

I can get an object name for the ObjectId for the DatabaseId sometimes.  However, I have cases where the ObjectId is 1050 and the IndexId is 256.  

5) How does one use the ObjectId when the IndexId is non-zero? 

I use an alert with a WMI query.  The where clause on the duration prevents multiple alerts from the same blocked process.  The duration is limited to twice the blocking threshold.  However, once in a while, the alert is not detected within this duration.  I'm thinking I can set the query to allow durations several times the threshold value and then check for duplicates. 

6) Can the TransactionId value be used to detect prior alerts from the same blocked process?  (I have a separate process that handles blocking status and recovery notices.)

DECLARE @AlertId int;

INSERT INTO alert.BlockingEvents (
 [LoginSid], -- Uint8[]
 [PostTime], -- DateTime
 [SQLInstance], -- String
 [IsSystem], -- Sint32
 [DatabaseId], -- Sint32
 [ComputerName], -- String
 [SessionLoginName], -- String
 [SPID], -- Sint32
 [TransactionID], -- Sint64
 [EventSequence], -- Sint32
 [IndexID] , -- Sint32
 [ObjectID], -- Sint32
 [TextData], -- String
 [Endtime], -- DateTime
 [Duration], -- Sint64
 [Mode] -- Sint32
)
VALUES (
 N'$(ESCAPE_NONE(WMI(LoginSid)))',
 N'$(ESCAPE_NONE(WMI(PostTime)))',
 N'$(ESCAPE_NONE(WMI(SQLInstance)))',
 N'$(ESCAPE_NONE(WMI(IsSystem)))',
 N'$(ESCAPE_NONE(WMI(DatabaseId)))',
 N'$(ESCAPE_NONE(WMI(ComputerName)))',
 N'$(ESCAPE_NONE(WMI(SessionLoginName)))',
 N'$(ESCAPE_NONE(WMI(SPID)))',
 N'$(ESCAPE_NONE(WMI(TransactionID)))',
 N'$(ESCAPE_NONE(WMI(EventSequence)))',
 N'$(ESCAPE_NONE(WMI(IndexId)))',
 N'$(ESCAPE_NONE(WMI(ObjectId)))',
 N'$(ESCAPE_SQUOTE(WMI(TextData)))',
 N'$(ESCAPE_NONE(WMI(EndTime)))',
 N'$(ESCAPE_NONE(WMI(Duration)))',
 N'$(ESCAPE_NONE(WMI(Mode)))'
)

SET @AlertId = SCOPE_IDENTITY();

EXECUTE alert.prBlockingMail
 @AlertId=@AlertId,
 @emailTo='dbas@xxx.yyy',

Hi,

I had come across an issue recently where the SQL server 2008 instance stopped accepting any connections and became unresponsive. I had to restart the SQL server to bring it back.

The bellow error is logged in SQL log. 

Error:

--------------------------------------------------------------------------------------------------------------------------------------

AppDomain 2 (database.dbo[runtime].1) created.

Unsafe assembly 'tldbwin32clientmanagedinterface, version=0.0.0.0, culture=neutral, publickeytoken=null, processorarchitecture=msil' loaded into appdomain 2 (database.dbo[runtime].1).

Failed Virtual Allocate Bytes: FAIL_VIRTUAL_RESERVE 1048576

-------------------------------------------------------------------------------------------------------------------------------------

What does this error mean and how this can be addressed? 

Any help on this appreciated. 

Thanks,

Vipin

Dear colleagues,

Let me explain our application first. We build and sell an ERP system. ERP systems are known for their large databases, containing thousands of tables with tables easily exceeding a million rows. Some of our customers need parts of our functionality in environments where wireless connection with the database is not feasible (e.g. inspections of a newly build ship hull or other boxes of Faraday, near machines that generate EMPs, etc.). For those cases we provide small parts of our functionality on a mobile device that is kept ‘in sync’ using Change Tracking.

Because mobile devices have more restrictions on the amount of available memory and because synchronizing your mobile device should not last more than a couple of minutes, a function that uses a frequently mutated table that contains over 10,000,000 rows in the database should not result in an implementation where you have an exact copy of this table on the mobile device. We only copy the columns and rows needed for the functionality on the mobile device. Below you see a (simplified) example of the incremental update statement for Change Tracking.

SELECT dbo.T_ProductionHeader.ProdHeaderDossierCode
,      dbo.T_ProductionHeader.ProdStatusCode
,      dbo.T_ProductionHeader.ProdHeaderCompletedInd
,      dbo.T_ProductionHeader.Description
,      dbo.T_ProductionHeader.PartCode
,      dbo.T_ProductionHeader.Quantity
,      dbo.T_ProductionHeader.StartDate
,      dbo.T_ProductionHeader.EndDate
FROM   dbo.T_ProductionHeader
INNER  JOIN CHANGETABLE(CHANGES dbo.T_ProductionHeader, @sync_last_received_anchor) AS CT
       ON CT.ProdHeaderDossierCode = dbo.T_ProductionHeader.ProdHeaderDossierCode
WHERE  (CT.SYS_CHANGE_CONTEXT IS NULL OR CT.SYS_CHANGE_CONTEXT <> @sync_client_id_binary)
AND    CT.SYS_CHANGE_OPERATION = 'U'
AND    CT.SYS_CHANGE_VERSION  <= @sync_new_received_anchor
-- In filter
AND    dbo.T_ProductionHeader.ProdHeaderCompletedInd = 0
AND    dbo.T_ProductionHeader.ProdStatusCode BETWEEN N'20' AND N'65'

The problem is that filtering the rows results in the situation that an update on the table should be translated in an insert or delete for Change Tracking. Take the filter above. Now assume a record is inserted with ProdStatusCode = '00'. Change Tracking signals an insert, but the filter statement causes this record not to be synchronized. If the ProdStatusCode is updated from '00' to '30', Change Tracking signals an update. This update is synchronized, but since a record is not present on the mobile device, nothing happens

What I did is creating my own ‘Change Tracking’ tables having the same structure as the Change Tracking tables that Microsoft uses. I also added simple triggers on the filtered tables. Whenever an update causes a record to move from outside the filter to inside the filter, I record an insert for that record in my custom ‘Change Tracking’ table. When the record moves from inside the filter to outside the filter, I record a delete. When the record is deleted, I remove it from my custom CT table. Furthermore I wrote a scheduled job that retrieves the retention period from sys.change_tracking_databases and removes all recorded information from my custom CT tables that is older than this threshold. Next, I added a UNION clause using my custom CT tables to the standard incremental insert and incremental delete statements for the mobile device, adding the records that should be inserted or deleted because of an update.

My question is, is there a more standard way of solving this problem or do I have to do all this stuff myself. I cannot imagine that we are the first to encounter this problem, so maybe more elegant and better solutions are already available?
