I have a SQL2000 db running a vendor custom app on a Win2000 sp3 server. The front-end is run on Citrix to the client. Can't change the app or the somewhat poor infrastructure of client. users starting to complain about slowness ( we can shadow them and this seems the case). On the SQL box all the standard perf counters look good (buffer cache at 100%, queue length always less than 1, memory and disk look good. The server currently has 2 nics doing load balancing. The network counter bytes/sec averages over 100,000. The network counter output queue length shows an average of 4,294,967,251 (That seems high but in reading on another sql perf site this counter doesn't always work). Any other ideas where I might look. Do these numbers look high?
Thanks
On an installation of sql 6.5, when I go to performance monitor, there are no sql counters. What gives? How can this be fixed,and do I have to reinstall,(wipeout data) to do it?
Is there anyway that you can automate performance monitor from the cmd line. I.e feed it some parameters like server and counters and receive a log file at the end.
CREATE TABLE [Perf] ([TransId] INTEGER,[FileNo] VARCHAR(80),[TimeInSeconds] INTEGER,[FileSizeMB] INTEGER,[FileName] VARCHAR(255),[StartDate] datetime)Ok!! Here's the Problem. I am working on a perf stats report. FileType is First 9 chars of the field FileName. I need to compare a similar filename from this month to last month or before ordered by file size. Maybe this is a very simple query but currrently my mind refuses to work. Seeking F1.
I have a server that has the following average readings :
No. CPUs = 1 % CPU = 2 SystemCPU Queue Length = 2 to 4 SQL Server:Buffer ManagerBuffer Cache = 99.85% RAM in the box = 1 GB MemoryPages/sec = 1 to 5 SQL memory in use ( using Task Manager ) = 250 MB Max worker threads = 255 Average number of connection = 60
So...........all indicators are that the CPU is idling, there is way enough RAM but we still have a ( in theory ) a congested CPU as the queue length is over 2 consistantly. Thing is, I need to work out if the CPU isnt working hard as the queue is long, or whether we can put extra databases/load on the box.
As the max worker threads are greater than number of connections ( 60 vs 255 ) we could reduce these as the number of users doesnt seem to alter much. BUT.......would this make much difference as if the 255-60=195 worker threads arent doing anything much, they shouldnt put any load on the server, right?
I have a 64-bit SQL Server running on 64-bit OS having 12GB of RAM. The Server only hosts our Application database (its a 30 GB database). There are no major process running on it. Despite of this, the Avg Pagessec shows a count of 1500 and the Avg Page Faultsec shows 22000. Is there any specific reason as to why this is happening? The %idle time of the disk is 87%. Also there is no major load on the server. Do let me know if you need any other input.
Are there really any benefit on using Read Uncommitted Isolation Level or having a NOLOCK hints for retrieve queries when the default Isolation level just Read Committed (not using COM+). I'm confused why the Community Server uses this technique perhaps for perf issues but I couldn't see any reason why...
The challenge: I have to extract and convert data between 2 SQL server systems - only 4 tables on the source systems, 8 tables on the target system. Source tables have between 5,000 rows and 16,000,000 rows. For most of the tables (for example Customer, which goes into 4 target tables), there will be 1 row in target tables for each row in the mapped source system table - so my 13.5M customer rows will end up as around 40M rows across the 4 target tables. So far, so good. But - this is a 24x7 online retail web-site, and to get the data across as a clean process, we require the smallest possible duration.
I have progressed on the customer migration, and am testing on a test environment (2xdual core HT processors, 4 GB ram) which was 2.15 million rows. Live environment is likely to be a 4xdual core with 8-16 GB ram.
I am trying to optimize the extract data flow, and have read the SSISperfTuning doc. I am now trying to put that into practice. I have a row size of approx 340 bytes, so based on that, and my test environment of 2.15 million rows, I work out at around 700 MB ram required to buffer the data. That is a factor of 7 times greater than the max buffer space for a data flow of 100 MB, which it seems, means I should divide the base MaxBufferRows (10000) by 7 to go down to 1400 rows?
I see a LOT of the following messages in my progress, when running with default settings: [DTS.Pipeline] Information: The buffer manager detected that the system was low on virtual memory, but was unable to swap out any buffers. 30 buffers were considered and 30 were locked. Either not enough memory is available to the pipeline because not enough is installed, other processes are using it, or too many buffers are locked.
I have this SP that takes several varchar columns and concatinates them all together then inserts them into a text field. I do this with a cursor which was the quickest way to get it done when it was setup...
However when I moved the process to a 2005 server (on the same physical server) the process drastically slowed down. On 2000 the process took about 7 min to handle all 350k+ rows with the processors hanging around 20-40%... On 2005 it took over 30 min (not sure how long it would take cause I killed the process) and the processors stay above 98%...
I have rewritten the process to use a while loop instead of the cursor (I wanted to do this anyways) and it had no effect. At this rate (about 1 row a second) it will take forever and this process runs everyday.
I'm loading my data warehouse using several SCDs. Some of these SCDs need to occur in sequence, while others can be run at the same time. I'm wondering what the best option for me is in terms of performance. Here is what I was considering:
1) Create a single package. Create two sequence containers --- one that will contain SCD loads that occur in sequence; the other sequence container contains SCD loads that occur in parallel.
OR
2) Create a set of packages for each SCD load. Then create a "Master" package that will use "Execute Package Task" components to call these packages.
The othe reason I want to bring up these difference ways to design an DW Load is because the second option is a "cleaner" approach, or a more organizational approach, to the load. The first option can get quite messy and large if you have several SCDs and several sequence containers. However, I'm looking for the fastest performance. Any thoughts?
This webcast from our partner, ETI, may be of interest to readers on the forum - we see questions quite often about high-performance interaction with other databases.
Trying to install 2005 Dev edition in xp pro, sp2.
Performance Monitor Counter Check Failed Error. Had to stop the install twice at the point it verified what components were to be included as the docs were not going to be installed. Resolved the issue.
Now it won't pass the system config test because the registry is not the way it wants it. I look up the messages and the only solution is to hack the registry and risk my system.
This is nuts.
Isn't there some way to restart cleanly without hacking registry keys ?
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:
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.
Hi 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.
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)

Hello I am new to .net and asp.net. On my local network i have our accounting system using sql 2005 and also a have an access database. We need to get this data to our web site sql 2005 database which is not connected to our network. Can somebody advise me on which would be the best and most secure way? Should i use Web Services to communicate between the network and the web server or use some other method like FTP, smtp? Thanks in advance for any help
Hi, Running a stored procedure in query analyser returns data but when running the asp.net page which uses that stored procedure returns an exception which is: General network error. Check your network documentation
Do you know what the problem could be please? Thanks
I have problems using SQL Profiler from a Windows2000 client PC to an SQL 7 server which is on a Windows NT machine. I can use profiler o.k. from an NT client (using Named Pipes), but can't seem to get it to work on my Windows2000 PC. I tried changing the Default Network Library on my PC to use TCP/IP, but it still does not work. The server has a default of Named Pipes. Can I get the server to use either Named Pipes or TCP/IP depending on whether the client communicating is an NT or Windows2000 PC? Or is this not the problem? Is there a problem with Windows2000 and Named Pipes?
Hi, I am trying to restore SQL7 DB from the Network M/C,here is the Procedure i am following
i have backup file on ABCsqlbackup where ABC is M/c Name on the network
from my Server i mapped ABCsqlbackup to the I drive then from enterprise magager i tried to restore DB and i gave path as I:xyz.bak for backup device location where xyz.bak is backup file name.
when i tried to restore like this it is giving error "unable to verify backup file location" and i checked in SQL server logs i found that message like.. "Unable to open Backup Device I:xyz.bak Failed to open.Operating system error,Unknown user name or bad password"
and that Sqlbackup directory is shared and it has full access to everyone.
Can anybody tell me how to restore from the Network, and where i am doing wrong.
Hi Friend, Is there any way in SQL Server by which I can locate the names of all the SQL-servers on the network. I was wondering if I can execute some query on Master database to find the above info??? Any clues??
