On my busy sql server my network output queue length is a very large number 4343559902. My research shows it should be a < 2, but have also seen some bugs related to this perfmon counter. Anyone dealt with this issue before?
View 1 RepliesRunning transactional replication, dedicated server for distributor. While performance in terms of latency is excellent (usually 1 sec, almost never higher than 4) the disk queue length on the distributor is extremely high (over 6 usually). Is this typical? On any other server I would be very concerned, but cpu and memory usage are excellent and as said, latency is good. what is recommended config for distributor? others see high queue length?

=============================
http://www.sqlserverstudy.com
Hi All,
we have collected perfmon data for a specific lun. Here is the background of the lun. The lun is Raid10 with 4 physical disks. We have problems interpreting the data. In the perfmon counter screen we have a max of 435 and average of 0.512. Can somebody tell us what is that we are missing? Any help is greatly appreciated.
Thanks,
Venkat.
Does anyone have any recommendation on whether it's better to monitor the average queue lenght for physical or logical drives? What about for a RAID set?
Just wondering,
thanks
PROBLEM: Sporadic spikes in Avg. Disk Queue Length with users freezing up until it comes down.
Server:
-SQL Server 2000 SP4
-Windows Server 2003
-4 Intel Xeon Processors 5130 @ 2.00 GHz
-4 GB of RAM (SQL Configured Dynamically with min. of 0 and max. of 3072)
-Max Worker Threads – 255
Environment:
-100 users with about 65 on Thin Clients going through a Remote Desktop Server
-Front End CRM package is a program called Telescript
-I do not use replication or any triggers, mainly just scheduled DTS packages
-Largest and most heavily used Database is 13Gbs with using a fill factor of 80 on my indexes
Recent Changes – The most notable thing that I changed in the last couple of weeks as this problem arose was the SQL Mail function. I started using that and created some DTS packages that sent out emails. Our user base has been steadily growing, but nothing drastic.
So Far – The buffer cache hit ratio is good and I have not seen any problems with memory so that is ruled out. The processor time never maxes out, but it does appear to double when the Avg. Disk Queue Length spikes. I re-indexed my active tables and performed shrinks over the weekend, but the problem occurred yesterday again. Sometimes it will last under a minute, but the problem is really when it lasts for several minutes. I used SQL Profiler to try and identify what the query was causing the problem, and while I see some large audit times, I cannot tell what the problem is. I had a hard time reading through that with all of the Stored Procedures that were invoked (ie. cursor fetches). The server itself is very new and has only been in use for about 2 months, so I couldn’t imagine it would be hardware fragmentation.
QUESTION: What else should I be looking at or could I use to figure out where this problem is stemming from? I am in a corner and could use any suggestions as to diagnose this problem.
Thanks in advance,

If I return the Average, Minimum, and Maximum values for the counter Physical Disk: Avg. Disk Queue Length, and those values are 10, 0, 87 respectively, which value do I use to compute the Avg. Disk Queue Length for a 4 disk array(RAID 10): Average, Minimum, or Maximum? The disk(lun) is on a SAN.
Hi,
I am sending the output of a query to a file and unfortunately every row is containing only a certain number of characters. My query has rows having length of 1500 characters for each row. When I get the query and send it to a file I am seeing only the first 250 characters for each row instead of 1500 characters.
I will be grateful if anyone can help me suggesting a solution for this problem.
I appreciate your help in advance.
thanks,

Hello every one
I am getting this in my event log from time to time . not sure what is that ?
Is this a hacker trying to send rubbish data to SQL through the port ?
Any help is appreciated .
Length specified in network packet payload did not match number of bytes read; the connection has been closed. Please contact the vendor of the client library. [CLIENT: someip]
I need to write data into a fixed column length file and was wondering the best (most efficient) way to tackle this. For example, the first few pieces of the report I'm working on now would be:
PacketID - Starting position 1, Field length 9
TransactionID - Starting position 10, Field length 9
Group number - Starting position 19, field length 10
PID/SSN - Starting position 29, field length 10
For the PID/SSN, if I have a PID it'll be 10 digits and fill the field length, if I don't I use SSN which is only 9 digits and enter a space as the 10th digit. Obviously if I don't have certain pieces of information I'll just need spaces of the specified length to satisfy the file format. I'm using SQL 2005. Thanks in advance for any help provided.
Hello,
I have an ODBC connection manager to a Progress database. In that database there is a column declared as a string of 10 characters long.
However, some data in this column is actually up to 15 characters long.
This makes my DataReader Source fail everytime I try to run my package because it sets the output column like this :
Datatype : Unicode string [DT_WSTR]
Length : 10
Is there any way to solve this without changing the datatype in the Progress database (that is beyond my control) ?
tanks in advance ...

Hello,
I am running a stored procedure thru' isql.
This returns only one field.
The sp is executed fine but if the data has length greater than 255 the data is truncated.
How do u capture the full output ?

:rolleyes:
To simulate problem do follows:
1. Add Script source component.
2. Add 2 string output collumns: F1 length 50, F2 length 110
3. Add Union All component connected to Script source component
4. Add Script transformation component connected to Union All component
5. Mark F1 and F2 as input collumns
6. In the Input and Output section of the script transformation component check that length of the fields is 50 and 110 correspondingly
7. Edit Union All component: change Union All Input 1 to <ignore> for Output collumns F1, and F2; change Union All Input 1 to F2 for F1 and F1 for F2; change back <ignore> for F1, <ignore> for F2; set back F1 for F1, F2 for F2; Click OK to save
8. In the Input and Output section of the script transformation component check that length of the both fields is 110 now.
So, be careful to select output columns values in Union All component. If you choose wrong field by accident, and replaced it with correct one straight away, the length of output column could be stored not as you expect an need.
My script component defines a (DT_WSTR, 450) output column named keyword. How can I access its length within the script, instead of hard-coding 450 as a constant?
My feeble attempts to tease this out through Visual Studio got me this far:
Output0Buffer.keyword.GetType.GetProperty("Length").GetValue(
but now I'm stuck. Also, if it matters, this is an asynchronous transformation component.
Thanks!
how do I make the output columns padded with extra space ? I intentionally set my output width larger than the input width, but the generated file is still jamming all the columns next to each other

This is info that I am still not certain about and I just need to make sure, my gut feeling is correct:
A.
When a procedure is triggered upon reception of a message in a queue, what happens when the procedure fails and rolls back?
1. Message is left on the Queue.
2. is the worker procedure triggered again for the same message by the queue?
3. I am hoping the Queue keeps on triggering workers until it is empty.
My scenario is that my queue reader procedure only reads one message at a time, thus I do not loop to receive many messages.
B.
For my scenario messages are independent and ordering does not matter.
Thus I want to ensure my Queue reader procedures execute simultaneously. Is reading the Top message in one reader somehow blocking the queue for any other reader procedures? I.e. if I have BEGIN TRANSACTION when reading messages of the Queue, is that effectively going prevent many reader procedures working simultaneously. Again, I want to ensure that Service broker is effectively spawning procedures that work simultaneously.
Thank you very much for the time,

is there any way or a tool to identify if in procedure the Parameter length was declarated less than table Column length ..
I have a table
CREATE TABLE TEST001 (KeyName Varchar(100) ) a procedure
CREATE PROCEDURE SpFindNames ( @KeyName VARCHAR(40) )
AS
BEGIN
SELECT KeyName FROM TEST001
WHERE KeyName = @KeyName
END
KeyName = @KeyName
Here table Column with 100 char length "KeyName" was compared with SP parameter "@KeyName" with length 40 char ..
IS there any way to find out all such usage on the ALL Procedures in the Database ?
For those of you who would like to reference my exact issue, I'm dealing with the RSExecution SSIS package at the "Update Parameters" data flow task, at the Script Component.
The script tries to split parameter data into name and value. Unfortunately, I have several reports that are passing parameters that are very large. One example has over 65,000 characters all in the normal "¶mname=value&parm2=value..." format.
The code in the script works fine until it gets to one of these very large parameter sets. I have figured out what is causing the issue. Here's some code:
Dim paramBlob as Byte()
paramBlob = Row.BlobColumn.GetBlobData(0, Row.BlobColumn.Length)
The second parameter of the .GetBlobData function takes an INTEGER as its count! Therefore, no matter what kind of datatype I pass to the string that the script will later split, it will be limited to 32767 characters.
THIS IS A PROBLEM!!!
Does anyone know a workaround for this issue? I need all of the parameter data to be reported, and I would hate to have to skip over rows like this. Also, if I'm missing something, please fill me in!
Thanks for your help in advance,

I am trying to narrow down this problem. Basically, I added 3 columns to my article table. It holds the article id, article text, author and so on. I tested my program before adding the additional field to the program. The program works fine and I can add an article, and edit the same article even though it skips over the 3 new fields in the database. It just puts nulls into those columns.So, now I have added one of the column names I added in the database to the code. I changed my businesslogic article.vb code and the addarticle.aspx, as well as the New article area in the addartivle.aspx.vb page. The form now has an additional textbox field for the ShortDesc which is a short description of the article. This is the problem now: The command parameters.length is 9 and there are 10 parameter values. Right in the middle of the 10 values is the #4 value which I inserted into the code. It says Nothing when I hover my mouse over the code after my program throws the exception in 17 below. Why is command parameters.length set to 9 instead of 10? Why isn't it reading the information for value 4 like all the other values and placing it's value there and calculating 10 instead of 9? Where are these set in the program? Sounds to me like they are hard coded in someplace and I need to change them to match everything else. 1 ' This method assigns an array of values to an array of SqlParameters.2 ' Parameters:3 ' -commandParameters - array of SqlParameters to be assigned values4 ' -array of objects holding the values to be assigned5 Private Overloads Shared Sub AssignParameterValues(ByVal commandParameters() As SqlParameter, ByVal parameterValues() As Object)6 7 Dim i As Integer8 Dim j As Integer9 10 If (commandParameters Is Nothing) AndAlso (parameterValues Is Nothing) Then11 ' Do nothing if we get no data12 Return13 End If14 15 ' We must have the same number of values as we pave parameters to put them in16 If commandParameters.Length <> parameterValues.Length Then17 Throw New ArgumentException("Parameter count does not match Parameter Value count.") 18 End If19 20 ' Value array21 j = commandParameters.Length - 122 For i = 0 To j23 ' If the current array value derives from IDbDataParameter, then assign its Value property24 If TypeOf parameterValues(i) Is IDbDataParameter Then25 Dim paramInstance As IDbDataParameter = CType(parameterValues(i), IDbDataParameter)26 If (paramInstance.Value Is Nothing) Then27 commandParameters(i).Value = DBNull.Value28 Else29 commandParameters(i).Value = paramInstance.Value30 End If31 ElseIf (parameterValues(i) Is Nothing) Then32 commandParameters(i).Value = DBNull.Value33 Else34 commandParameters(i).Value = parameterValues(i)35 End If36 Next37 End Sub ' AssignParameterValues38 39 40 41

We have a Windows 2003 Web Edition server serving a site through IIS. It connects to a Windows 2003 Standard Edition server running SQL 2000 SP3a.
This site receives the following error as seen in the topic:
[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.
We've configured the server network utility to only allow TCP/IP connections. The connection string for the site is as follows:
<%
' FileName="Connection_ado_conn_string.htm"
' Type="ADO"
' HTTP="false"
' Catalog=""
' Schema=""
MM_connSpankMSSQL_STRING = "Provider=sqloledb;Data Source=SERVER_IP,1433;Network Library=DBMSSOCN;Initial Catalog=ourmaindb_1;User ID=ourmaindb_1;Password=hotcookies;"
%>
Any ideas or tips on solving this issue? We've noticed it is due to larger queries as smaller ones do work with no problems.
The servers are behind a BSD box running iptables, has 1433,1434 along with standard web ports wide open. Anything outbound is allowed.
Some further testing via ODBC on the IIS server improved things. No more connection pooling for the SQL Server driver allows for 1/3 of the query to run. Still 2/3s of it doesn't show up, and that general network error message appears.
Should have 330 rows if it works right.

While running a DTS, many times the error message: "[DBNETLIB][ConnetionWrite (WrapperWrite()).]General network error. Check your network documentation." appears.
Does somebody knows why?
I am running the DTS from a computer (not the server where the DTS is stored) and it is connected without any problem when this happens.

Hi Every one,
I am using .Net 1.1 for my web application.

My application is running fine, as i can login to it and also able to view pages. But when i open Order management(having 3K records) its give me error,
General Network Error. Check your network documentation
I have also searched many articles and tried following solutions but nothing working
- connectiontimeout = 0, max pool size = 7500/100, pooling = false
- SSL disabling enforce security false as mentioned in microsoft kb article.
And there's nothing any issue with hardware/firewall as my application's login and other forms are working fine(which use same database with same connection string)
Can any one please help me to solve this error?

I use sqlclient to connect directly from my mobile 5 pocketpc to a sql server 2005 database on my desktop.
I use a sqldatareader to traverse the results of a query that delivers 2 fields: (1) the filespec, and (2) the image field.
I use a filestream with a binary writer to write the contents of the image data to the pocketpc's storage card.
I have a test table with 10 images, not one more than 4 MB. I cannot complete a test run prior to receiving the general network error.
The pocketPC is connected via activesync to the desktop, and I connect to the database with:
Integrated Security=false;
user id=sa
password=admin.
Any help with this strange error would be greatly appreciated.

Hi
I have Lookup task to determine if source data should be updated to or insert to the customer table. After Lookup task, the Error Output pipeline will redirect to insert new data to the table and the Output pipeline will update customer table. But these two tasks will be processing at the same time which causes stall on the process. Never end.....
The job is similiart to what Slow Changing Dimention does but it won't update the table at the same time.
What can I do to avoid such situation?
Thanks in advance,

I am working on an OLAP modeled database.
I have a Lookup Transformation that matches the natural key of a dimension member and returns the dimension key for that member (surrogate key pipeline stuff).
I am using an OLE DB Command as the Error flow of the Lookup Transformation to insert an "Inferred Member" (new row) into a dimension table if the Lookup fails.
The OLE DB Command calls a stored procedure (dbo.InsertNewDimensionMember) that inserts the new member and returns the key of the new member (using scope_identity) as an output.
What is the syntax in the SQL Command line of the OLE DB Command Transformation to set the output of the stored procedure as an Output Column?
I know that I can 1) add a second Lookup with "Enable memory restriction" on (no caching) in the Success data flow after the OLE DB Command, 2) find the newly inserted member, and 3) Union both Lookup results together, but this is a large dimension table (several million rows) and searching for the newly inserted dimension member seems excessive, especially since I have the ID I want returned as output from the stored procedure that inserted it.
Thanks in advance for any assistance you can provide.
