Backup Failed: System.Data.SqlClient.SqlError: Backup And File Manipulation... Must Be Serialized

Jul 11, 2007

Using SQL Server 2005 Server Management Studio, I attempted to back up a database, and received this error:

Backup failed: System.Data.SqlClient.SqlError: Backup and file manipulation operations (such as ALTER DATABASE ADD FILE) on a database must be serialized. Reissue the satement after the current backup or file manipulation is completed (Microsoft.SqlServer.Smo)



Program location:

at Microsoft.SqlServer.Management.Smo.Backup.SqlBackup(Server srv)
at Microsoft.SqlServer.Management.SqlManagerUI.BackupPropOptions.OnRunNow(Object sender)



Backup Options were set to:

Back up to the existing media set

Overwrite all existing backup sets



I am fairly new to SQL 2005. Can someone help me get past this issue? What other information do I need to provide?

Error: Fcb::close-flush: Operating System Error 21(The Device Is Not Ready.) Encountered

May 23, 2007

We are using sql server 2005 Enterprise Edition with service pack1



I got the following error messages in the SQL log



The operating system returned error 21(The device is not ready.) to SQL Server during a read at offset 0x00000000090000 in file '....mdf'. 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.
fcb::close-flush: Operating system error 21(The device is not ready.) encountered.

I got these errors for about 2 hrs and after that I see these messages in the sql log



Starting up database ' '
1 transactions rolled forward in database '' (). This is an informational message only. No user action is required.
0 transactions rolled back in database ' ' (). This is an informational message only. No user action is required.
Recovery is writing a checkpoint in database ' ' ( ). This is an informational message only. No user action is required.
CHECKDB for database '' finished without errors on (local time). This is an informational message only; no user action is required.



Can anyone please help me in troubleshooting this issue. Why this migh have happened.



any help would be appreciated.

System.Security.SecurityException: Request For The Permission Of Type 'System.Data.SqlClient.SqlClientPermission, System.Data

Aug 21, 2006

I have created a windows library control that accesses a local sql database

I tried the following strings for connecting

Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Trusted_Connection = true"

Dim connectionString As String = "Data Source=localhostSQLEXPRESS;Initial Catalog=TimeSheet;Integrated Security=SSPI"



I am not running the webpage in a virtual directory but in

C:Inetpubwwwrootusercontrol

and I have a simple index.html that tries to read from an sql db but throws

the error

System.Security.SecurityException: Request for the permission of type 'System.Data.SqlClient.SqlClientPermission, System.Data, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

etc etc

The action that failed was:

The type of the first permission that failed was:

The Zone of the assembly that failed was:

I looked into the .net config utility but it says unrestricted and I tried adding it to the trusted internet zones in ie options security

I think that a windows form connecting to a sql database running in a webpage should be simple

to configure what am I missing?

FCB::Open: Operating System Error 32(The Process Cannot Access The File Because It Is Being Used By Another Process.) Occurred W

Dec 3, 2007

Hello all,
I am running into an interesting scenario on my desktop. I'm running developer edition on Windows XP Professional (9.00.3042.00 SP2 Developer Edition). OS is autopatched via corporate policy and I saw some patches go in last week. This machine is also a hand-me-down so I don't have a clean install of the databases on the machine but I am local admin.

So, starting last week after a forced remote reboot (also a policy) I noticed a few of the databases didn't start back up. I chalked it up to the hard shutdown and went along my merry way. Friday however I know I shut my machine down nicely and this morning when I booted up, I was in the same state I was last Wenesday. 7 of the 18 databases on my machine came up with

FCB:pen: Operating system error 32(The process cannot access the file because it is being used by another process.) occurred while creating or opening file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf'. Diagnose and correct the operating system error, and retry the operation.
and it also logs
FCB:pen failed: Could not open file C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf for file number 1. OS error: 32(The process cannot access the file because it is being used by another process.).

I've caught references to the auto close feature being a possible culprit, no dice as the databases in question are set to False. Recovery mode varies on the databases from Simple to Full. If I cycle the SQL Server service, whatever transient issue it was having with those files is gone.
As much as I'd love to disable the virus scanner, network security would not be amused. The data and log files appear to have the same permissions as unaffected database files. Nothing's set to read only or archive as I've caught on other forums as possible gremlins. I have sufficient disk space and the databases are set for unrestricted growth.

Any thoughts on what I could look at? If it was everything coming up in RECOVERY_PENDING it's make more sense to me than a hit or miss type of thing I'm experiencing now.

Any way I can recover it?

System.Data.SqlClient.SqlException: Error Converting Data Type Numeric To Decimal.

Aug 31, 2004

Hi There,

I'm using C# to get a value for a DOUBLE precision variable, called "Length", from a textBox using the following line:

Length = Convert.ToDouble( txtLength.Text )

I'm also using the following lines to prepare my stored procedure call:

arParms[9] = new SqlParameter("@Length", SqlDbType.Decimal, 5);
arParms[9].Value = record.Length;

My stored procedure has the following parameter definition:

@Length decimal(9,3)

My problem is that if someone types a value bigger than 999999 in the textbox he will get for sure the following error:

System.Data.SqlClient.SqlException: Error converting data type numeric to decimal.

I don't know how to either make sql or C# to truncate the value or catch the exception to automatically assign 0 to the parameter.

Please Help.

Error: 5123 CREATE FILE Encountered Operating System Error 5A(Access Denied.)

Mar 22, 2006





HI ,



This is a problem I encountered when I had to detach a database file (type .mdf):



1) I went to the MS SQL Management Server Studi and detached my database file successfully from a connection called Workhorse.



2) I needed to place the .mdf database file into a zip file in order to put it on a remote server. I did this using Shared Portal. This was also successful



3) However when I tried reattaching the database file, I got this error:

CREATE FILE encountered operating system error 5A(Access denied.) while attempting to open or create the physical file "CProgram FilesMSSQL ServerMSSQLData<databasename>.mdf'



Q) The database file and log file (ldf) exist in the correct directory so I don't know what happened. Can any one help?



Thanks much

SQL Server Error Message - Operating System Error 10038: An Operation Was Attempted On Something That Is Not A Socket...

Nov 20, 2006

My apologies...I wasn't for sure where to post an error like this...

Over the last 2 months I have gotten this SQL Server error (twice). All existing processes will continue to work, however no new processes can be created and users cannot connect to the server. This is the exact text of the message in the SQL Server error log.

Operating system error 10038: An operation was attempted on something that is not a socket...

Error: 17059, Severity: 18, State: 0

Error accepting connection request via Net-Library 'SSNETLIB'. Execution continuing.

Error: 17882, Severity: 18, State:

While we can typically just stop SQL Server Service and restart the services...I have found it is best to restart the machine during non-production times to take care of any 'residual' effects of this error.

The SQL Server 2000 SP4 box with Windows 2003 Standard SP1 is well maintained by our I.T. team and it typically will run 4 or 5 months without a reboot.



Thank you...

Sep 11, 2003

Hi, who have ever met the following errors, share an information of what could cause it??? I can't find any info that could help me find the reason. My DB went to SUSPECT mode and in the log file I got:

ForwardLogBlockReadAheadAsync: Operating system error 997(Overlapped I/O operation is in progress.) encountered.

Operating system error 997(Overlapped I/O operation is in progress.) on device 'd:MSSQLdataiservice_Log2.ldf' during ForwardLogBlockReadAheadAsync.

Error: 3414, Severity: 21, State: 1

Error: 9001, Severity: 21, State: 1

Unexpected error while commiting a ShrinkFile operation
/*************************/

What is weird the 997 error occured twice during last night and the DB went into suspect mode only after the sencond one.

The database restored but it's a second time for the last month just getting a bit annoying.

Thanks for any help

Operating System Error 1784 On DB Restore

Apr 11, 2007

Hi there. Could someone help me out.
I'm performing a log restore and getting the following error within the SQL Server Error Log.

During restore restart, an I/O error occurred on checkpoint file 'G:MSSQL.1MSSQLBackupdxsh.CKP' (operating system error 1784(error not found)). The statement is proceeding but cannot be restarted. Ensure that a valid storage location exists for the checkpoint file.

IT's a very basic Restore command and i do have not specified it to Restart.

Having checked the MS website for 1784 it suggests the following:

The supplied user buffer is not valid for the requested operation

Can anyone tell me what is wrong here and why it is creating a checkpoint file or even what it is and how to overcome the error message.

TIA

Error Message 25080 The Operating System Does Not Support Encryption Again

Nov 19, 2007

A customer of my program is getting the SQL CE error message "The operating system does not support encryption".


I've seen several threads on this issue, but none of them seem to apply to my problem. This is a Windows Forms application, so no device and no web service.

The OS is a German Windows XP - so there shouldn't be any issues regarding strong encryption. It even runs in Windows 2000 in our test VPC.

We're using SQL CE 2005.

Any ideas what I could check?
