MS SQL 2000 Bandwidth Problems
Jan 30, 2007
I am building a SQL server on a Windows 2000 Server box. It has a public IP and we have 4 T1 lines. After I install SQL 2000 it will run for about 30 minutes and then it will take up all the bandwidth on the network to such a degree that my users are unable to access the internet. I have been troubleshooting this over the last couple of days. This morning I reinstalled SQL with just the default DB's and after 45 mins it brought the network down again. Any help on this would be greatly appreciated.

Hi there SQL Team
I hope I’ve posted this in the right section.
We have a customer, call them customerA
CustomerA has just employed a new Chief Information Officer.
The New CIO would like to make a few changes to the current way we have things right now.
Bare with me as I explain our environment.
We have The following Servers
Application Server[FSS (Dual DC Xeon 2.33GHz CPU, 4GB RAM, 3x72GB hdd RAID]
Database Server [FSS (Dual DC Xeon 2.33GHz CPU, 4GB RAM, 3x72GB hdd RAID)]
Both the above servers sit in a fully fault tolerant environment with daily backups power generators etc etc etc.1000MB network everything work 100%
Now my question:
The new CIO would like to move the DB server out of this environment to a remote building downtown, and have the application server connect to this remote db server.
Is this advisable?
What are the required connection speeds, so that the end user does not have to wait for a response?
What is the recommended response time IIS should give?
Please also note that we are in South Africa and broadband is VERY expensive / unreliable.
The CIO would like to install a 2Mbit radio link from this building to the ISP I’m not sure on the cost, but do know that this type of link is very unstable,
Their failover will be a 512kb fixed line or diginet line. Cost about ZAR 8000.00 per month
The application is extremely data / graphs intensive as it contain property information.
I think they average about 16000 visitors daily, not a lot.
If anyone can give me any input i would appreciated.
Thanks

HiI have two SQL2000 servers in different sites, once a day approximately1M of data in the form of a large update is required to be transferedbetween the 2. We have use of a 2M pipe between the servers but thereis no quality of service, the other users on the pipe are traders sothere must be no interruption in the quality of their bandwidth at anytime.Is there any way of throttling back the data transfer between the twoservers to restrict its bandwidth use. Obviously we want to retain themax bandwidth on our local network.The pipe is administered by a seperate company so we do not have adminaccess to their gateways, routers etc.. so a solution which we canimplement on our database servers would be the easiest.I am not sure if this is the right newsgroup for this but anyinformation would be greatThanksMark

Does anyone know a wayto compress data between two database connections over "low bandwidth" lines in order to speedup datatransfer?
Used connections are Oracle<->SQL2000 and SQL2000<->SQL2000.

Hi
I am evaluating the possibility of replicating a database over a network to our HQ from the control site (one way). The original database is on SQL server.
The database is likely to grow to many terabytes so we would be using transactional replication.
The table to be replicated recieves about 500 records per second.
The table will probably consist of a record key (8 byte int), site ID (4 byte int), reading (8-byte float), and timestamp (8 byte timestamp). All up, 28 bytes + whatever overhead exists.
MINOR DETAIL:
The HQ's copy should be preferably no more than 1 hour behind the control site's. This would be a long-term setup that would last for many years. Our link is currently about 2 MB/s, and is fairly reliable.
QUESTIONS:
I'm guessing that (bytes/record)*(records/second) won't be the whole story. Does anyone have an estimate of the average data efficiency factor for transactional replication?
How would I go about calculating how much bandwidth would be needed? Is there a formulae hiding somewhere?
Thanks in advance.
Simon.

Hi to all experts,
I have a server with about 50 databases and the server bandwidth usage is 15-30 Mbps.
I need to know which databse is consuming the bandwidth.
Can you tell me what is the best way (if any) to monitor bandwidth usage per database?

All:
One of the new tests that we are running have to do with load testing an application with a constrained network pipe. I like this. One of my beefs has been related to stored procedures that return bloated result sets. This new set of tests potentially gives me some more amunition to use when I review stored procedures. A piece that I would like to produce as a result of this has to do with establishing an output bandwidth standard for our database servers. I have a few biased ideas but I would like to know if any of you have any similar pre-existing standards along this line. Any help?

Hi All,
I am setting up P2P replication for a high latency environment (although at 100MBit per sec, the bandwidth is not a serious issue ).
I have noticed that at high load, the bandwidth between Distribution and Subscriber servers maxes out at 1MBit per second (our network bandwidth is 100MBit per second).
This causes transactions to 'back up' and when the load reduces they 'catch up' and synchronise.
Does anyone know where this limitation of 1Mbs is being enforced and what is the way round it?
I have seen the -SubscriptionStreams NN parameter, but this is not applicable in P2P replication.
Any advice would be appreciated.
Thanks

My objective is to use Enterprise Manager to move (copy) my SQL db from the server to my windows desktop computer.
I downloaded MSDE and am having trouble installing it, no doubt because I do not understand the documentaion (ReadMeMSDE2000A.htm).
When I try to run setup, I get that message that says:
"A strong SA password is required for security reasons. Please use SAPWD switch to supply the same."
Considering my purpose, do I need a "strong" SA password? If not, how do I get around it? If yes, how do I set it up?
I am a Mac user so I have poor windows skills, please make it as painless as possible for me, thanks!

Hi,
Just upgraded some development desktops to Vista Business. However we need
to still connect to some older remote windows 2000/SQL 2000 servers.
Trying to setup an ODBC system DSN on our Vista Business local desktop we get the
following errors -
-START ERROR WINDOW-
Connection Failed:
SQLState: '01000'
SQL Server Error: 772
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]ConnectionOpen
(SECDoClientHandshake()0.
Connection failed:
SQLState: '08001'
SQL Server Error: 18
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]SSL Security Error
-END ERROR WINDOW-
Any help greatly appreciated as this is stopping us from making
database/table connections etc. We've checked the firewall setup and all is well there.
PS - we can still connect fine using XP or windows 2000 desktops and their
local DSNs.

I am attempting to move some SQL 2000 databases to SQL 2005. My main production database does not seem to want to move. When I use the SQL 2005 GUI the .bak backup file is marked 'Incomplete'. When I attempt to restore the backup file I get a 'RESTORE detected an error on page (0:0) in database' message. I saw a thread in the SQL Express forum suggesting trying to restore from the T-SQL level to get the GUI out of the picture and I get the same 'error on page (0:0)' message. However when I take the same file and use SQL 2000 Enterprise Manager it restores with no problems.
Any ideas?
Thanks

Hi, I am trying to edit some data from a SQL2000-datasource in ASP.NET 2.0 and have a problem with a column that has bit-data and is used for selection. SQL2005 works fine when declaring <SelectParameters> <asp:Parameter DefaultValue="TRUE" Name="APL" Type="boolean" /> </SelectParameters>When running this code with SQL2000, there are no error-msgs, but after editing a record the "APL"-column looses its value of 1 and is set to 0. Looks like an issue with type-conversion, we've hit incompatibilities between SQL200 and 2005 with bit/boolean several times before. So, how is this done correctly with SQL2000? (I've tried setting the Type to "int16" -> err. Also setting Defval="1" gave an err) ThanksMichael

I recently had to reinstall a new instance of SQLServer 2000, but was unable to use the previous server name. As a result, my Access2000 front end is not happy with it's linked tables. I can't seem to find anyplace within Access to universally change the address of the SQLServer used as the back-end for all linked tables.
When I do try to access the linked tables through Access, I get an error, and the option to change the server location. When I try to type-in the new SQLServer location, there is an attempt to reconnect to SQLServer, but a whole lot of errors are generated, and none of the data is transferred into the Access table.
I really don't want to have to re-do my Access front end, so it seems it would be easiest to somehow reinstall SQLServer to have the same server location it used to. Is there a good way to completely erase all traces of SQLServer so that I can have better luck reinstalling it to the same location it used to be in? Just using the uninstall program from SQLServer doesn't seem to be cutting it.
Thanks!

I've created a small company database where the tables reside in a SQLServer database. I'm using Access 2000 forms for a front end.I've got a System DSN set-up to SQL Server and am using links withinAccess 2000 to get to the SQL Server tables.My forms worked fine until I made a few minor changes to the databaseschema on SQL Server (e.g. added a foreign key, or added a column).After that, all the links break - I click on a table link and get anerror msg like "invalid object name."Deleting the links after a schema change and re-adding the links seemedto fix the problem. The forms I'd already created seemed to work fineafter re-creating the links.But then I got more advanced with my forms. I have it set up so thatfor certain entry fields, the combobox gets populated with values froma table (the description appears in the drop-down and the correspondingprimary key value gets populated in the table). I created a number offorms using this technique, entered data, and everything worked fine.Made a small schema change and it broke everything -- not the actualtable links, but the functionality for the drop-downs. My values nolonger appeared, and this was true for forms that accessed tables whoseschemas did not change.This is driving me nuts. Is there any way to keep my forms frombreaking each time I make a small schema change?Thanks.- Dana

I've just started getting this EXCEPTION_ACCESS_VIOLATION (0xc0000005) on machines using Windows 2000 sp4 connecting to SQLServer. This is crashing JVMs (multiple Sun versions and BEA also) in the Java VM frame (outside our code). This has just started recently - perhaps with the last set of patches? Has anyone else seen this or know what I could do to get more information? Could this be related to updates to named pipes?
Thanks!

We are using an Access 2000 project to view our SQL Tables and using Access 2000 Runtime to Access the forms in the project. We have written in a locking system in VB and removed the video controls to prevent users from accessing the same records. But of course now we need to make the video controls available. This has now thrown up the problem of multiple users accessing the same records. We have tried to write code to lock records when then video controls are used but this is not working as well as we hoped. Can anyone please suggest any way of setting up locking on SQL using triggers from the Access frontend? or any other types of locking systems that could be written in the Access front end.

Hi,
I worked on a project in ASP.NET using SQL server 2000 as the back end. Its a conversion application that I rewrote in ASP.NET using C#. I need to import the old data in Access db into SQL server 2000 and I have very little knowledge about doing it. The data in not a direct one -one transformation. There are considerable changes to the Database design and data types. Any help and suggestions wud be really helpful. Also, any article links wud be great.

We have a SQL Server 7.0 system in NT 4.0 environment. We upgraded our users to Access 2000 and started to work with this. Now we installed a new
server which is Windows 2000 based and the domain is different from
the SQL servers domain. We then installed Access 2000 on Windows 2000
to use with terminal server. But I noticed that there was a problem
with the program. I then looked at the program which was written on Access 2000 and saw that the tables and views can't be seen. The program runs but
I can't see the views and tables. Another thing is access disconects from SQL Server when I want to see the tables. So what can be the problem.
In one part there is an Access 2000 on Windows 2000 server. On the other part SQL Server 7.0 on Windows NT 4.0. And Access can't see the tables in SQL server.

Yet, I am able to open the file through Access and have necessary permissions and I know no one else has it opened. The mdb is password protected and I have provided the correct login information in the DTS connection.

Hello!I would like to change the SQL server 2000 from Standard version toDevelopment edition. I have two database running on this server, bothreplicated, with few jobs, etc ... Can you recommend the easiest way to dothis? I heard, it would be as easy as, detaching the databases, deletingcurrent SQL software, installing different one, and attaching the olddatabases back. I doubt that is true, so that's why I'm asking here for anyreal-life instructions.Thanks for your input!Kind regards,Dejan--

Hi guys,
I have a performance related question about the DTS package in sqlserver 2000 which i have developed
We have developed a DTS package which will migrate a view 'ATTRITION' from Sqlserver 2000 to an Oracle database.The design of the package is as follows
First step: It checks for the existance of the table 'ATTRITION' in oracle database, if table 'ATTRITION' is not there it will create a table called 'ATTRITION' in the oracle db.If the table 'ATTRITION' is already present in the oracle db,then the table is truncated.
Second step: The view 'ATTRITION' is migrated to Oracle table 'ATTRITION'.
For the migration, i have used a connection object which connects to sqlserver 2000 and for oracle connection i have used another connection object 'Microsoft ODBC driver for oracle' and i have joined both the connection objects with 'Transform data task' task which maps one to one from sqlserver 2000 where view 'ATTRITION' exists with oracle database where Table 'ATTRITION' exists.
Roughly i have around 65000 rows in 'ATTRITION' view of sqlserver 2000 which needs to be migrated.When im running the package on my system it takes around 4 minutes to migrate all the rows but when im running it on the server it takes a lot lot of time more than 1 hour.
The view definition im using has more than 10 tables joined together.But if its a problem of query used in the view,and if i run the view seperately it quickly displays the data hardly takes 1 minute. and even if i run the package on my local pc it doenst take much time.Now my confusion is why its taking soo much time on server.If i create a indexed view then will it solve my problem.Please suggest...
Thanks in advance
