Processes Blocking RESOURCE MONITOR, Normal Behaviour?
Apr 12, 2007
Today I ended up in a situation where I had a process with total six "subthreads" (identified by different execution context) (seen in Activity Monitor). All of these had blocking=1. The server didn't function properly, I don't know the details of these problems, since I was not present at that time. We had to kill the processes. What is the process id 1, "RESOURCE MONITOR" in SQL Server 2005, seen in Activity Monitor? Is it fatal if some processes are blocking RESOURCE MONITOR? How can one end up in such situation, is it normal or a bug somewhere?
The server is a 64-bit Windows server having SQL Server 2005 SP1.
Yesterday I had a CLR stored procedure running on another server. The procedure uses System.Data.SqlClient.SqlConnection to access this server. The procedure started about 11.4.2007 22:22. The procedure created a connection to the SQL Server and created a select that should return 1,5 million rows. During fetching the rows (about after 800 000 rows) the procedure crashes to an error:"".NET Framework execution was aborted by escalation policy because of out of memory. " Naturally the procedure couldn't close the SQL Server connections, since it was forced to end.
The details if the processes as seen from Actívity Monitor (I only have screenshots so I can't copy-paste...):
The main process:
Process id: 69
status: suspended
open transactions: 1
command: SELECT
Application: .NET SqlClient Data Provider
Wait time: 578
Wait type: ASYNC_NETWORK_ID
CPU: 1375
Physical IO: 22
Memory usage: 2
Login time: 11.4.2007 22:22:05
Last batch: 11.4.2007 22:22:05
Blocked by: 0
Blocking: 1
Execution context: 0
Two "subthreads", there are five similar.
Process id: 69
status: suspended
open transactions: 0
command: SELECT
Application: .NET SqlClient Data Provider
Wait time: 35293046
Wait type: CXPACKET
CPU: 4875
Physical IO: 2214
Memory usage: 2
Login time: 11.4.2007 22:22:05
Last batch: 11.4.2007 22:22:05
Blocked by: 0
Blocking: 1
Execution context: 1
Process id: 69
status: suspended
open transactions: 0
command: SELECT
Application: .NET SqlClient Data Provider
Wait time: 35293031
Wait type: CXPACKET
CPU: 4875
Physical IO: 2210
Memory usage: 2
Login time: 11.4.2007 22:22:05
Last batch: 11.4.2007 22:22:05
Blocked by: 0
Blocking: 1
Execution context: 2
The rest three subthreads differ from the above by having different wait time, CPU, physical IO and execution context.

I have upgraded a MS SQL database from 6.5 to 7.0. The database functioned fine in 6.5, now I have a table that is locking due to a blocking process. If I kill the process all is fine, but am trying to determine what is causing the process to hang. Has anyone experience any similar situations.

Hi there,
Currently using SQL Server 2000 (SP4). The following condition started occurring last week:
- Server has excessive blocking
- Majority of the processes are in runnable state
- Excessive blocking happens for a few mins. and repeats again during the day. Does not happen at night.
- Nothing on the server errorlog, profiler
- CPU averages 40 - 50% at that point of excessive blocking
Any help would be greatly appreciated.
Thanks.

Last night I received this error
Process ID 152:3 owns resources that are blocking processes on Scheduler 2.
When I did an BCC INPUTBUFFER I found it was sp_MSadd_repl_commands27hp which is doing the insert into MSrepl_commands has any else noticed and issue w/ sp_MSadd_repl_commands27hp blocking itself. At the time I had about 10 million records to move. I was using the default log reader settings so I was batching them in 500 chunk intervals.
I am wondering if any else has had problems like this? I basically see it whenever I move too much data through my replication server.
I found the followoing link http://support.microsoft.com/kb/319892
Sample Scenario
Client 1 connects to SQL Server.
Client 1 runs a Transact-SQL command that starts a transaction and performs data modification.
For example: begin tran
update authors set au_lname = 'test'
Client 1 becomes IDLE, shows up as sleeping, and awaiting a command with an open transaction in the sysprocesses system table.
Clients 2 through 255: Approximately 254 more clients log on to SQL Server and issue a SELECT from the authors table. These clients will all become blocked on the original update.
Client 1 tries to commit the transaction but it becomes queued because all the worker threads are tied up by clients 2 through 255.
I am afraid that I am seeing this more then I would like does anyone know a way to prevent this from happening?

The following question applies to SQL Server 8.0.2187 (2000 + SP4+916287/914384/898709/915065/915340):
We have now twice had an incident where the same SQL Server has stopped responding. The only workaround is to restart the SQL Service. After this occurs, the log is filled with the following messages:
2007-09-10 16:42:14.29 spid3 Process ID 197:320 owns resources that are blocking processes on Scheduler 1.
2007-09-10 16:42:14.31 spid3 Process ID 74:324 owns resources that are blocking processes on Scheduler 5.
We haven't been able to pinpoint a cause or reporduce the problem on a dev server. I've seen several posts about this issue online but not many answers. Does anyone have any advice on how to troubleshoot this issue?

All;
We have a Windows App and Web App that share business objects which points to a single database. When a Windows user logs in, an average of 50 processes are created in the first few seconds and never go away. The details window is blank and they all remain sleeping from that point on.
I have stepped through the code to see if there is anything odd going on but most of the processes are created when validating the number of parameters the stored procedure has or the length of the stored procedure name. This translates to 1000-1500 processes on average.
Is this normal? Will it hurt performance? Is there a way to remove them?

We are facing lot of problems with Blocking,can any one help us in this matter,The problem is as follows
We have SQL Server 7.0 running on Nt4.0, and three web servers and 5 application servers are accessing SQL server.
Till Yesterday everything was fine,Suddenly today more than 18 processes
were blocked by other(Like chain),First i killed some blocking process,then it was fine,once again it started and continuously some processes are blocked by other,and i found that all blocking process are running from webservers.I ran SQL Profiler to get some information,but no use.
I am not understanding why suddenly it happend,because we have't modified anything.Is there any way to overcome this situation,this is production server.
because of this users are getting slow responce/no responce.
----Here i want to know why it happend?

Can any one help me please
Thanks

If I'm on a remote machine, meaning a computer not in the WSFC cluster, and I open SSMS 2014, point it to a SQL Instance, and open activity monitor:
1. I get all the panes and charts except % Processor Time.
2. Then, if I authenticate to the cluster's domain by mapping a drive with valid domain credentials, I'm free to put performance counters in the Perfmon - - - but SQL Activity Monitor shuts down with“The Activity Monitor is unable to execute queries against server SQL-V01INSTANCE1..Activity monitor for this instance will be placed into a paused state.Use the context menu in the overview pane to resume the activity monitor.
Additional information: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))(Mscorlib)”
3. Of course, the Activity monitor can't be resumed via the context menu. Removing counters and closing the perfmon do not work. I dropped the mapped drive and rebooted the machine. That brought back 95% of the information in the Activity monitor.
4. Further experimentation showed that any mapping of drive shares present on the SQL Server to the computer running SSMS cut off functionality of the 'overview' pane in the remote machine's SQL Activity monitor -- the monitor that had been trying to watch the server offering the shares.

Hi. Sorry if I am asking a stupid question since I am an absolutely beginnerin SQL Server. Here is the question . . .About 13 hours ago, I got my SQL Server 2000 to index a table which has 104million records. At first the CPU usage was high. But after an hour or two,the process has seemed dead and the Enterprise Manager has had no response.The CPU usuage dropped to zero and has been jumping between 0 to 5%. Theharddisk indicator has been blinking at a rate of roughly three times pertwo seconds.Is this normal? Has anyone got any idea how long the process would take? Ihave assigned 1.8GB of RAM to the SQL service and is currently taking upabout 1GB.

Hi guys, I've been thinking about this problem now for some time but somehow I don't know if my "solution" for it is right. I'd like to read your opinion.
There is a Capital table with Capital_Nr, Capital_Name, Capital_Population, Country_Nr and Country_Name as attributes.
I know the table is chaotic so I brought it to 3NF :
Capital table : Capital_Nr, Capital_Name, Capital_Population, Country_Nr(foreign key)
Country table : Country_Nr and Country_Name
Ok so I guess the table should be now in 3NF, but what intrigues me is in what NF the table originally was. I tried then to use Codd's definition of 2NF : "a 1NF table is in 2NF if and only if none of its non-prime attributes are functionally dependent on a part (proper subset) of a candidate key". In my opinion the original candidate keys could only be {Capital_Nr},{Country_Nr} and {Country_Name}, each one of them single, i.e. separate from each other. So, as there is no composite candidate key, I can affirm that the original table was in 2NF. Am I right ?
Thanks !

I am wondering what normal disk I/O should be.
i know it verys depending on use but im looking for an average.
here is an idea of what we have
there is about 10 centers doing replication to our primary server.
we have about 80 users connecting directoy to our primary server using MS Dynamics through CITRIX.
we have a few other apps use the database as well however i am fairly certin its Dynamics generating our disk IO
Hardware wise we have a powerful blade connected to a raid 5 SAN with 15000 rpm disks.
normaly the disk IO stays fairly low but every so often it goes crazy and im thinking it shouldn't
Below is a sample of our disk IO from perfmon over 2 minutes or so. as you can see everything looks ok untill 04/15/2008 10:12:49.470 when the Disk I/O % goes above 100%

Hey All, I'm trying to decide what's the 'best' to use. I've been designing and creating database for a while and have pretty much always used a surrogate key and not a normal one. I've finally had some free time to start studying more so in my spare time and read up and come accross a lot of guides, articles and stories that tout that normal keys should be used whenever possible as they're a better identifier and that surrogate keys should only be used when there is not a readily available normal key. Now perhaps I'd be open to accepting that but absolutely every database I come across tends to only use surrogate keys. For example I'm doing an authentication system from scratch and am looking at the User table. Now of course the user name has to be unique, should that be the primary key or should I have a seperate column with a guid or an incrementing int or the like as the primary key? I can certainly see that username could be used. I can also see how it may be easier when looking through the data tables to identify who/what a table is refering to with a surrogate key. However it still seems sort of sloppy, for lack of a better word, to me. Where now I could have somebody's username (or any other piece of data used for this purpose) spread accross a lot of other tables. And while writting this I just thought of the scenario that perhaps somebody needs their username changed, with this method now the ids need to be changed on all the related rows of all the other tables whereas with a surrogate key it wouldn't matter. Anyways I'm mostly looking for opinions on which way to go (not just with the user sample, but more in general).Thanks.

Hi all,
I've been running a long query which takes almost 39 seconds in Query Analyzer. After creating a Stored Procedure (with the same query) I expected to run it faster bcoz I heared that SP has a cache, and its a faster technique. But I didnt gain any performance improvments.
Can somebody clear my confusion, what I'm doing wrong.
Thanks!

We have a payroll database that needs to be backed up just before completing the payroll for that period. I need to create a batch file that a normal user can run that will tell the database to back up and then tell the user when it is done so they can continue working. Is there an easy way to do this without giving the users special permissions? I don't want to give them backup op status. Any help would be appreciated.

Hello,
Is performance of web application (ASP.NET + SQL Server 2005 Wrg edition + Win Server 2003 Web edition) running on server with one core duo/4 CPU generally comparable to the performance of the same application running on the same server with 2/4 physical CPU’s?
Thank you for your ideas!

Hi,
I was wondering if it is possible to reference a value in a previous row as a field in a normal select statement, for example:
SELECT a.user_id, a.name, b.user_id, b.name
FROM Users a
LEFT OUTER JOIN Users b
WHERE (b.user_id = a.user_id - 1)
Unfortunantly my user_id values are not in sequence so I get null entries using that code. Instead of doing something as basic as -1 is there another way to reference the previous row?

I have an application that stores xml data in an unusal manor. Basically a SQL Key column and an XML string.The XML string is not really standard XML, but it is what it is, and I'm stuck with it. It is in the format;
<row key="Value.01" xml:space="preserve"><c1>FirstName</c1><c2>LastName</c2><c3>10 Street Address, City ST 012345-1234</c3><c4>5</c4><c5>50</c5><c6>500</c6></row>
I am able to pull values out via
SELECT
p.value('(./c1)[1]', 'VARCHAR(8000)') AS c1,
p.value('(./c2)[1]', 'VARCHAR(8000)') AS c2
FROM dbo.UserXMLTable
CROSS APPLY XMLRECORD.nodes('/row') t(p)
where p.value('(./c1)[1]', 'VARCHAR(8000)') like 'First%'
However I've been struggling with selecting row with a LIKE clause. Something like ;
SELECT *
FROM dbo.F_UserXMLTable
where XMLRECORD.value('(./c1)[1]', 'VARCHAR(8000)') like 'First%'
I have tried a number of permutations of XML syntax but so far have been stumpled.
Please note "<row key="Value.01" xml:space="preserve">" has a <SP> in the name 'row key' .

I just ran across an interesting problem, that makes no sense. I
built
an SSIS package that updates a column, using an transformation
script.
Testing in Debug mode everything runs perfectly, but when I have SQL
sever agent run the package it insert null into the new column.
Any thoughts or suggestions would be greatly appreciated.

As pointed out in the SQL Express blog recently http://blogs.msdn.com/sqlexpress/archive/2006/11/15/sql-express-sp2-and-windows-vista-uac.aspx (look for the section that starts "Watch out!"), the SQL Express SP2 argument ADDUSERASADMIN will not work correctly if the user is a normal user. If the user is a member of the BUILTINAdministrators group then Vista will prompt to elevate them to allow the Admin rights to be effective.
However, my reading of the blog post is that if they are normal users, Vista will prompt for the Administrator credentials. This effectively runs the install as the Administrator user. So the ADDUSERASADMIN argument works, but adds the Administrator rather than the normal user.
This is not what I need to happen. Is there any way around this? I have a ClickOnce application. Is there any way to restrict the ClickOnce install to require the user to be a member of the BUILTINAdministrator group?
Thanks.

SQL7 SP1 NT4 SP5
Hi.
Very long story and I will not bore you with it. What I need to do is call a stored procedure and from within that stored procedure, initiate other sp and get out before those other sp are finished running.
I know I can execute a job but my volume would be about 1 job per second with a life of 2-5 seconds. So in a very short period of time, I can stack up a large volume of jobs.
Anyone have any better ideas ?
Help Please !@!!

I have an SQL server with several (100) users connected. When I run a long running process, it severely impacts user performance. The long running process is a store procedure with several cursors.
Are there SQL configuration settings that would reduce the impact of these long running processes on other Users?
