Hi,
I have a fairly complex application running which has numerous connections on various threads accessing my sql 2005 database.
Every now and then I find that one of my connections is being blocked by process with a pid of -2.
I assume this is some system process.
The only way I can get my application going again is to restart the sql server.
Can someone tell me what process -2 is?
cheers,
Robert
We are using SQL server 6.5 and currently have about 100 users connections at a given
point in time. The application is Visual Basic 5.0 based and it allows users to create
MS Word documents from the application. These documents names are stored in a table which basically
acts as a reference table. Every time a document needs to be attached to a record
this table is called with an insert/update query. This results in an exclusive page/table
lock and ends up into a blocked process. This finally results into a major halt for
all the system users.
Manual killing of these blocked processes frees up the resources and brings things back to normal
although disruptive to the users.
Any clue as to why the blocked processes are not able to free themsevles up ?
Are we missing something in our SQL configuration that will help us with unblocking
these processes ?
If I kill a blocked process, why does the current activity window still show the process? Both processes, blocking and blocked, are scheduled tasks. Also, the blocked process is still listed as a running task in the manage scheduled task window.

Has anybody experienced a process being blocked by SPID -1.
we have tables that load overnight. Sometimes a user will try to run a query up against that table while the table is loading and a deadlock occurs. I do not notice this until I get into the office. By this time many tables have not loaded. Is there a way to have SQL6.5 automatically Kill deadlock processes.

I have a question about blocked processes. My manager wants to know how you can know the following when a blocked process is encountered.
The job, program and the statement that is causing the blocking. I have figured out how to determine the database involved but not a lot else. Such as in the blocked process report there is a waitresource field. How to you decipher it?
The report also tells you the client application, but in this case it just states the Micro focus Net Express as the client, not the job or program that is running.
I have an inputbuf listed but it just shows the database id, and the object id. And I am not sure how to locate the object id in this case, I am guessing sys.objects, but I do not seem to find that one.
I have read many things on MSN about the blocked process report, but it does not seem to go into great detail.
I seem to have all the pieces, but do not exactly know how to quickly tie them all together.
Any help would be appreciated.
Thanks,
Kathy
According to BOL you can configure an Alert to notify you when the blocked process threshold has been exceeded:
SQL Server 2005 Books Online
blocked process threshold Option
Use the blocked process threshold option to specify the threshold, in seconds, at which blocked process reports are generated. The threshold can be set from 0 to 86,400. By default, no blocked process reports are produced. This event is not generated for system tasks or for tasks that are waiting on resources that do not generate detectable deadlocks. For more information about deadlock detection, see Detecting and Ending Deadlocks.
You can define an alert to be executed when this event is generated. So for example, you can choose to page the administrator to take appropriate action to handle the blocking situation.
Can someone provide some direction on exactly how this is done? Does it require a Service Broker and queue?

I am using VB2005 Express. I had, evidently, a simpler version of SQL but deleted it, as was recommended, and then downloaded SQL 2005 Express. Now when trying to open an SQL database in a project I get that Information Message.
FURTHERMORE after loading the new SQL it wiped out all of my projects in VB 2005. The back up files were wiped out also.
That was naughty!
Thank you in advance for a reply.

i'm going nuts with SQL server notification thing. I have gone throigh this artical which tells how to set user http://www.codeproject.com/KB/database/SqlDependencyPermissions.aspx. This article show how to create new user and setup for sql server notification.But In my case user was alredy existing in database. which is very common senario in most cases. So i did following( check the SQL script below) but then i get this error
"A connection was successfully established with the server, but then an error occurred during the login process. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)"
this my sql script

Hi!
I am running a SELECT query in SQL Server 6.5 and continue to get the following message (error?):
This command did not return data, and it did not return any rows
DB-Library Process Dead - Connection Broken
I'm running it directly from Enterprise Manager on the same box as the database itself. The problem seems to be specific to the query itself as minor changes work fine. There are lots of joins involved - the query joins 3 tables and a view, that view joins 3 tables and a sub-query, and that sub-query joins 2 more tables. Simple queries on the view seem to indicate that the view works fine.
I'm a web/DB developer, but not much of a DBA. Has anyone run into this problem and know what may be causing it? Please let me know if you need to see the code of the query and/or the view. (Will replies be emailed to me automatically? If not, please email to tmenier@ontrack.com.)
Thank you!
Using Server 6.5 ISQL. This occurrs after running a 5 to 10 processes ???
View 2 Replies View RelatedI have a stored procedure whose sole purpose is to assign a value to 26 variables using select statements (i.e. select @enroll = (select count(distinct upid)fromPATLOG). Some of the souces are tables and some are views.
After the 26 variables are assigned they are written to a table using a INSERT into Values (@enroll, @tbrconsents,...)
My problem is that when I run the SP I get the message
"This command did not return data, and it did not return any rows"
"DB-Library Process Dead - Connection Broken"
and nothing is written to the table. I`m fairly new to SQL programming so I haven`t a clue where to start. The SP has run successfully four times intermittantly but I can`t get it to run consistantly.
Any help or insights would be appreciated.

Hello,i have a doubt here, after a close the connection, i still can see the last stored procedure active in the LOCKS/PROCESSID in enterprise manager of SQL SERVER.I think i'm closing the connection well
Try
If Me.ID > 0 Then
Dim strSql As String = "SP_CHANGECLASSCONTENTS"
Dim sqlcommand As New SqlCommand(strSql, New SqlConnection(ConnStr))
sqlcommand.CommandType = CommandType.StoredProcedure
sqlcommand.Parameters.Add("@PerformActivation", SqlDbType.Bit).Value = 0
sqlcommand.Parameters.Add("@PerformInactivation", SqlDbType.Bit).Value = 0
sqlcommand.Parameters.Add("@PerformDelete", SqlDbType.Bit).Value = 1
sqlcommand.Parameters.Add("@PerformUndelete", SqlDbType.Bit).Value = 0
sqlcommand.Parameters.Add("@PermanentDelete", SqlDbType.Bit).Value = CBit(PermanentDelete)
sqlcommand.Parameters.Add("@Class_ID", SqlDbType.Int).Value = _id
sqlcommand.Connection.Open()
sqlcommand.ExecuteNonQuery()
sqlcommand.Connection.Close()
Else
Err.Raise(10205, "CLASS", "CLASS ID is empty")
End If
Catch ex As Exception
_err = ex.Message
Return Err.Number
End Try
Ok sql-masters, I'm stumped and need someone to come to the rescue.
The issue: nested transactions = dblibrary process dead; broken connection or runaway process.
On the first try it usually bombs with the dblibrary... error. If I continue trying to run it, it will run, but actually runaway.

I have just installed MS SQL Server 2005 Express edition along with the SSMSE. I am using windows authentication. When I open SSMSE it connects me to a 'local instance' of the server. From there I right click on Database and select to add a new Database and I get the error above. I think I only need to allow local connections to the engine but I have tried allowing remote conections with all varations of named pipes and TCP/IP. I am running on Windows XP SP2 (home).

Hi,
I was trying to extract data from the source server using OLEDB Source and SQL Server Destination when i encountered this error:
"Transaction (Process ID 135) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction.".
What must be done so that even if the table being queried is locked, i wouldn't experience any deadlock?

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.
Dear list
Im designing a package that uses Microsofts preplog.exe to prepare web log files to be imported into SQL Server
What Im trying to do is convert this cmd that works into an execute process task
D:SSIS ProcessPrepweblogProcessLoad>preplog ex.log > out.log
the above dos cmd works 100%
However when I use the Execute Process Task I get this error
[Execute Process Task] Error: In Executing "D:SSIS ProcessPrepweblogProcessLoadpreplog.exe" "" at "D:SSIS ProcessPrepweblogProcessLoad", The process exit code was "-1" while the expected was "0".
There are two package varaibles
User::gsPreplogInput = ex.log
User::gsPreplogOutput = out.log
Here are the task properties
RequireFullFileName = True
Executable = D:SSIS ProcessPrepweblogProcessLoadpreplog.exe
Arguments =
WorkingDirectory = D:SSIS ProcessPrepweblogProcessLoad
StandardInputVariable = User::gsPreplogInput
StandardOutputVariable = User::gsPreplogOutput

How do I use the execute process task? I am trying to unzip the file using the freeware PZUnzip.exe and I tried to place the entire command in a batch file and specified the working directory as the location of the batch file, but the task fails with the error:
SSIS package "IngramWeeklyPOS.dtsx" starting.
Error: 0xC0029151 at Unzip download file, Execute Process Task: In Executing "C:ETLPOSDataIngramWeeklyUnzip.bat" "" at "C:ETLPOSDataIngramWeekly", The process exit code was "1" while the expected was "0".
Task failed: Unzip download file
SSIS package "IngramWeeklyPOS.dtsx" finished: Success.
Then I tried to specify the exe directly in the Executable property and the agruments as the location of the zip file and the directory to unzip the files in, but this time it fails with the following message:
SSIS package "IngramWeeklyPOS.dtsx" starting.
Error: 0xC002F304 at Unzip download file, Execute Process Task: An error occurred with the following error message: "%1 is not a valid Win32 application".
Task failed: Unzip download file
SSIS package "IngramWeeklyPOS.dtsx" finished: Success.
The command in the batch file when run from the command line works perfectly and unzips the file, so there is absolutely no problem with the command, I believe it is just the set up of the variables on the execute process task editor under Process. Any input on resolving this will be much appreciated.
Thanks,

I am designing a utility which will keep two similar databases in sync. In other words, copying the new data from db1 to db2 and updating the old data from db1 to db2.
For this I am making use of the 'Tablediff' utility which when provided with server name, database, table info will generate .sql file which can be used to keep the target table in sync with the source table.
I am using the Execute Process Task and the process parameters I am providing are:
WorkingDirectory : C:Program Files (x86)Microsoft SQL Server90COM
Executable : C:SQL_bat_FilesSQL5TC_CTIcustomer.bat
The customer.bat file will have the following code:
tablediff -sourceserver "LV-SQL5" -sourcedatabase "TC_CTI" -sourcetable "CUSTOMER_1" -destinationserver "LV-SQL2" -destinationdatabase "TC_CTI" -destinationtable "CUSTOMER" -f "c:SQL_bat_Filessql5TC_CTIsql_filescustomer1"
the .sql file will be generated at: C:SQL_bat_Filessql5TC_CTIsql_filescustomer1.
The Problem:
The Execute Process Task is working fine, ie., the tables are being compared correctly and the .SQL file is being generated as desired. But the task as such is reporting faliure with the following error :
[Execute Process Task] Error: In Executing "C:SQL_bat_FilesSQL5TC_CTIpackage_occurrence.bat" "" at "C:Program Files (x86)Microsoft SQL Server90COM", The process exit code was "2" while the expected was "0". ]
Some of you may suggest to just set the ForceExecutionResult = Success (infact this is what I am doing now just to get the program working), but, this is not what I desire.
Can anyone help ?
I got this message from sql
"Server was unable to process request. ---> A connection was successfully established with the server, but then an error occurred during the pre-login handshake. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.) "
Does anyone know what happen?

I'm pulling data from Oracle db and load into MS-SQL 2008.For my data type checks during the data load process, what are options to ensure that the data being processed wouldn't fail. such that I can verify first in-hand with the target type of data and then if its valid format load it into destination table else mark it with error flag and push into errors table... All this at the row level.One way I can think of is to load into a staging table then get the source & destination table -column data types, compare them and proceed.
should I just try loading the data directly and if it fails try trouble shooting(which could be a difficult task as I wouldn't know what caused error...)
Hi Folks,
I am having this table locking issue that I need to start paying attention to as its getting more frequent.
The problem is that the data in the tables is live finance data that needs to be changed and viewed almost real time so what I have picked up so far is that using 'table Hints' may not be a good idea.
I have a guy at work telling me that introducing a data access layer is the only way to solve this, I am not convinced but havnt enough knowledge to back my own feeling up. (asp system not .net).
Thanks in advance

Hi,
Issuing 'dbcc shrinkfile (log ,truncateonly)'
I get the error message below. Books online doesn't say any more.
Can anyone explain? I am the only user connected to the db at the time, no jobs are executing.
Cannot shrink log file 2 (log) because all logical log files are in use.
(1 row(s) affected)
DBCC execution completed. If DBCC printed error messages, contact your system administrator.
What is SPID -1? I see nothing listing it in any activity monitor, but it has just recently started blocking some processes.
Thanks,

I'm running a heavy SELECT query using WITH (NOLOCK). This still causes other processes trying to INSERT in one of the tables to get blocked.
I thought the locking hint would prevent from blocking other processes?
I am getting the following error message when I tried installing the 2005 Developer Edition from the MSDN kit.

Hi all,
I have an SQL Server 2005 mirroring config with "High availability". Twice over the past four weeks, the principal server started logging to the event log:
"All schedulers on Node 0 appear deadlocked due to a large number of worker threads waiting on DBMIRROR_DBM_EVENT" I checked the database activity monitor and indeed there were lots of processes in DBMIRROR_DBM_EVENT.
The database was totally unresponsive to queries (all got timeouts), and no failover was done.

I restarted the database and everything came to normal.
As you can imagine, the problem is really serious.
Should I forget about mirroring? Anyone has experienced something similar?

Hi,
I'm trying to upload the ASPNETDB.MDF file to a hosting server via FTP, and everytime when it was uploaded half way(40% or 50%)
I would get an error message saying:
"550 ASPNETDB.MDF: The process cannot access the file because it is being used by another process"
and then the upload failed.
I'm using SQL Express. Does anybody know what's the cause?
Thanks a lot
