Measure network bandwidth of SQL Server

Hi everyone,
I'm using SQL Server 2k5. Now I get a request to measure the network traffic of a certain DB. For example, how many GB data are in and out from a DB in 1 hours or longer. Is it possible to use SQL profiler or some other tools to grab the information? Thank
you very much for your time and efforts.
regards,
Oliver

In addition to Shanky's response,
you can use tools like the Wireshark, in order to monitor it. You can use filter like:
filter capture on port 1433:
http://en.wikipedia.org/wiki/Wireshark
* Wireshark is perfect to capture the traffic, but it will not tie specific packets to specific queries. for this you should use the combination of profiler as well.
** This is not a recommendation to use specific application or to install anything on production!
If you want to monitor network traffic between web application hosted in IIS and SQL Server, both of which are running on the same server, then the faster and easier way is monitoring the IIS (there is build-in log file that you can use), or from the application
itself. but those options have some limitations. please check this link: http://dba.stackexchange.com/questions/45846/how-do-i-monitor-bandwidth-used-by-sql-server-on-port-1433

Network requirements for SQL Server Replication

Hi,
Can any one tell me what is network requirements for SQL Server replication.
I have successfully configured the replication on LAN with active directory but I am unable to configure it on WAN.
Can anyone tell me how WAN can be configured for sql server replication.
Any help in this regard will be highly appreciated.
Regards,
Muhammad Imran

Hi Muhammad,
In addition to Prashanth’s post, please also check the following things to optimize SQL Server replication with a WAN link.
• Initialize the Subscriber from a backup.
Publishing the execution of stored procedures as opposed to replicating each operation performed by the stored procedure.
Leveraging Subscription Streams.
For more information, please review the following blog:

[Forum FAQ] How do I create calculated measure using AMO in SQL Server Analysis Services?

Introduction
In SQL Server Analysis Services (SSAS), you can create a calculated measure in SQL Server Data Tool (SSDT)/Boniness Integrated Development Studio (BIDS). Sometimes you may need to create calculated measure by using AMO in a C# or VB project.
In this article, I will demonstrate so how to create calculated measure using AMO in SSAS?
Prerequisites
Before create calculated measure using AMO, you need to ensure that the following components were installed in your server.
The multidimensional database AdventureWorks Multidimensional Model 2012
A SQL Server with SSIS and SSAS installed
The AMO libraries installed:
X86 Package (SQL_AS_AMO.msi)
X64 Package (SQL_AS_AMO.msi)
Solution
Here is the detail steps to create calculated measure using AMO in SSAS.
Open SSDT and create a new SSIS project.
Drag Script Task to the design surface.
Click SSIS-> Variables to open the Variables window and add two variables that used to connect to the server and database.
Create a connection to connect to SSAS server.
Rename the connection name to ssas.
Double click the Script Task to open Script Task Editor.
Add Connection and Database variables to ReadWriteVariables textbox and then click Edit Script button.
Add AMO reference in the Solution Explore window.
Copy the script below and paste it into the script.
Dim objServer As Server
Dim objDatabase As Database
Dim strDataBaseID As String
Dim objCube As Cube
Dim objMdxScript As MdxScript
Dim objCommand As Command
Dim strCommand As String
objServer = New Server
objServer.Connect("localhost")
objDatabase = objServer.Databases("AdventureWorksDW2012Multidimensional-EE2")
strDataBaseID = objDatabase.ID
If objDatabase.Cubes.Count > 0 Then
objCube = objDatabase.Cubes("Adventure Works")
If objCube.MdxScripts.Count > 0 Then
objMdxScript = objCube.MdxScripts("MdxScript")
objMdxScript = objCube.MdxScripts(0)
Else
objCube.MdxScripts.Add("MdxScript", "MdxScript")
objMdxScript = objCube.MdxScripts("MdxScript")
End If
objCommand = New Command
strCommand = "CREATE MEMBER CURRENTCUBE.[Measures].[Multipy Measures By 3]"
strCommand = strCommand & " AS [Measures].[Internet Sales Amount] * 3, "
strCommand = strCommand & " VISIBLE = 1 ; "
objCommand.Text = strCommand
objMdxScript.Commands.Add(objCommand)
objMdxScript.Update()
objCube.Update()
End If
objServer.Disconnect()
Then you can run this SSIS package to create the calculated measure.

Thanks,
Is this a supported scenario, or does it use unsupported features?
For example, can we call exec [ReportServer].dbo.AddEvent @EventType='TimedSubscription', @EventData='b64ce7ec-d598-45cd-bbc2-ea202e0c129d'
in a supported way?
Thanks! Josh

Network load balancing SQL Server 2012

Hi all,
Out of pure curiosity, would the following scenario to load balance work:
* Create an NLB of 2 nodes
* On each node, install sql server, in my case 2012 std
* Create a merge replication which manages identity columns between the 2 servers. One node is the publisher the other one the subscriber
If I were to implement this, what would be the risks ?
Thanks
Olivier

SQL Server does not support load balancing.
Yes you can do what you describe. You need to use "sticky sessions" to make sure users always get the same server, which kind of defeats the purpose of load balancing.
I would suggest looking into an AlwaysOn availably group cluster instead. Not the same thing, but built in and you can redirect read only users to use a replica.

Hello,
If you see error descriptioon it gives access denied so basically it is because of some access issue.I guess You must be using some domin account for installation make sure it is added as local administrator also instead of using NT Authority network
service as SQL server service account use local system account .
Below link would help
http://serverfault.com/questions/212135/access-is-denied-error-installing-sql-server-2008-on-windows-7
You can also browse to setup.exe file and RK on it and select run as administrator

Firewall issue with centralized SQL server - port 52384

Hi,
I have dedicated, centralized MS SQL 2012 server for our internal infrastructure with few instances. There is dedicated named instance SC for SC Family Products running on TCP port 1435. Also Server Browser running on UDP 1434 is enabled. I'm trying to install
SCOM 2012 R2. I got to the step Configure the Operational Database and here, I encountered a problem. I try to connect to my SQL server and put into
Server name and instance name SQL\SC and into SQL Server port 1434 or 1435, it doesn't connect. If I turn off firewall on SQL server, it connects without problems. On SQL server, I already have allowed incoming communication on ports UDP 1434
and also TCP 1433-1436. Than, I found out, that I need to allow in TCP 135 so I did it. It didn't work. Than I allowed TCP 49154-49157 for reporting services - it still didn't work. Last thing I allowed (using Microsoft Network Monitor) was TCP port 52384
and suddenly, it worked .
I know what UDP 1434 and TCP 1433-1436 are for. Also, I understand why I have to open 135 and 49154-49157. But I am pretty confused by the port 52384 - what is it for ? Why it isn't mentioned in documentation ? I am pounding with this problem for a while,
and also, I found out, that my SC VMM is not working, if I do not allow all of these ports - so, probably not only used by SCOM ?
Can anyone explain what's that port for ? Or why it's not enough to open 1434, 1433-1436, 135 and 49154-49157 ?
Thanks
Tomas

Hi,
I didn't install SCOM yet. I am stuck at installation, till I figure out why port 52384 needs to be opened.
1. My SQL Server Configuration Manager is set like this:
Protocols for SC - TCP/IP Enabled
IP2
Active : Yes
Enabled : Yes
IP Address : ipv4 ip address of server
TCP Dynamic Ports : (blank)
TCP Port : 1435
So, that should be ok, right?
2. If I turn off firewall on SQL, everything connects ok - so based on that, I suppose that SCOM server firewall is configured ok . It's issue on SQL.
On SQL server, I have these inbound rules:
COM+ Network Access (DCOM-In) - TCP 135 enabled
HTTP/HTTPS - TCP 80,443 enabled
SCOM Reporting - TCP 49154-49157 enabled
SQL UDP ports - UDP 1433-1437 enabled
SQL TCP ports - TCP 1433-1435 enabled
SCOM 52384 - TCP 52384 enabled <- this is the port I don't understand, why it should be opened
If I disable any of these rules, my connection will not pass. I figured out those ports using Microsoft Network Monitor on SQL server.
3. Those databases do not exist yet. I am stuck at 3th step of Operations Manager Setup - at Configure the operational database.
There are fields Server name and instance name, SQL Server port, Database name, Database size, Data file folder, Log file folder
. First two are writable and the rest is greyed out. If I don't turn off firewall and I don't enable all rules from point 2 on SQL server and than put in the SQL server name with instance (SQL\SC) and port 1434 (or 1435) it gives
me red cross, and rest of the page stays greyed out - so, it's unable to connect. If I turn off firewall, or enable all the rules in previous point (2) I am able to change name of the database, database size, data/log file folder. But if I disable any
of those ports, it stays greyed out - I am concerned about port 52384, why it should be opened? What is it for? Why it isn't mentioned in any documentation? Or am I doing something wrong?
Thanks
Tomas

Measure the Network bandwidth usage

Hi,
For application server, is there any Oracle tool to be used to measure the Network bandwidth usage?

Hi，
The following policies are supported in Window 7
Computer Configuration | Administrative Templates | Network | Background Intelligent Transfer Services (BITS) |Set up a maintence schedule to limit the maximum network bandwidth used for BITS Background transfers
or Set up a work schedule to limit the maximum network bandwidth used for BITS Background transfers
see this link
http://blogs.msdn.com/b/wmi/archive/2011/02/02/bits-more-flexible-bandwidth-limit-policies.aspx
And download speed is also related with your network connection, your ISP, setting in your router, your system perfrormance...

===================================
The system cannot find the file specified
I have tried from so many forms. This is so frustrating. Thank for everyone/anyone who wants to help. So this is what happened: I had to uninstall my previous sqlserver 2012(which worked great) for some reason, and I uninstalled everything from that download.
Then I installed the trial edition of sql server 2012 (64 Bit) and It wouldn't connect to the database. (Error mentioned above.) My local DB is COWBOYS. (COWBOYS is also my computer name.) After this, I have tried downloading sqlexpress and sqlserver 64bit
many times and cannot connect to my local DB.
How do I connect to my Local DB?
Also, I think this might help: (When I run sqlserve.exe, which I was able to find in C:\Program Files\Microsoft SQL Server\110\LocalDB\Binn, I get an error: Your SQL server installation is either corrupt or has been tampered with(Error getting
instance ID from name). Please uninstall then re-run setup to correct this problem.
I would happily re install it, if it wasn't my 20th time.
I don't have any remote connections, I don't use username/password, only window authentication. I work mostly on visual studio, but without able to store /retrieve data, I don't know how to survive.
May be the solution is very simple, but I am too frustrated.
Some of the things I have tried:
From a command prompt, enter one of the following commands:
net start "SQL Server Agent (MSSQLSERVER)" OR
net start "SQL Server Agent(instancename)"(for instance)
on my sql configuration, I cannot start anything because there is nothing there to start. I can post more details, if that would help. Also, some more details about the error:
Details
Product:
SQL Server

Message:
An error has occurred while establishing a connection to the server. When connecting to SQL Server, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error:

Explanation
SQL Server did not respond to the client request because the server is probably not started.
User Action
Make sure that the server is started.

Any one that can help me, I will be greatful. Thank you so much. p.s. please ask me anything if you have any questions.

It sounds like there are a couple things going on here. First check if you have a successful install of SQL Server, then we'll figure out the connection issues.
Can you launch SQL Server Configuration Manager and check for SQL Server (MSSQLSERVER) if default instance or SQL Server (other name) if you've configured your instance as a named instance. Once you find this, make sure the service is started.
If not started, try to start it and see if it throws an error. If you get an error, post the error message your hitting. If the service starts, you can then launch SSMS and try to connect. If you have a default instance, you can use the machine
name in the connection dialog. Ex: "COWBOYS" where Cowboys is the machine name. However, if you named the SQL Server instance during install, you'll need to connect using the machine\instance format. Ex: COWBOYS\Romo (where Romo
is the instance name you set during install).
You can also look at the summary.txt file in the SQL Server setup error logs to see what happened on the most recent install. Past install history is archived in the log folder if you need to dig those up to help troubleshoot, but the most
recent one may help get to the bottom of it if there is an issue with setup detecting a prior instance that needs to be repaired.

How can I connect to SQL server database thru local network by using JSP?

I'm currently doing a project by using JSP..And I need to display record from the SQL Server database in our school's local network. May I know how can I do that? How can I write the code so that I can able to access the SQL Server databsase Throught school's network by using JSP? Please tell me step by step how can I do that. I'm using Tomcat 4.1 as Web Server. And I had J2SE and J2EE installed in my computer.

first you have to establish a ODBC DSN on your computer,
that connects to the database...you can do that from your control pannel.
i assume that the TOMCAT server is residing on your computer....(if the webserver is in other computer then you would have to create a System DSN on the data sources ODBC option in the settings>control pannel of that machine)
then you can use that DSN name to connect to the data base from the class file....for further assistance on how to create the class that access the tutorials in sun site.

Azure Webjobs with EF DB - A network-related or instance-specific error occurred while establishing a connection to SQL Server

Hi,
I have been trying to get a very simple WebJob developed and deployed onto Azure with little to no luck. I have a MVC Website which has a common project which handles my Data Access Layer with Entity Framework. I have created a WebJob project
using Visual Studio and added the following lines of code to the Manual Trigger Function
[NoAutomaticTrigger]
public static void ManualTrigger(TextWriter log, int value, [Queue("queue")] out string message)
RitualDBEntities db = new RitualDBEntities();
log.WriteLine("Function is invoked with value={0}", value);
List<Location> locations = db.Locations.ToList();
string msg = string.Empty;
foreach (Location location in locations)
msg += location.Name;
message = msg;
log.WriteLine("Following message will be written on the Queue={0}", message);
In my app.config of my WebJob i have the following connection strings:
<add name="RitualDBEntities" connectionString="metadata=res://*/RitualDBEntities.csdl|res://*/RitualDBEntities.ssdl|res://*/RitualDBEntities.msl;provider=System.Data.SqlClient;provider connection string="data source=ritual-pc\sqlexpress;initial catalog=RitualDB;integrated security=True;persist security info=False;MultipleActiveResultSets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
<add name="RitualContext" connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=RitualDB;Data Source=ritual-pc\sqlexpress" providerName="System.Data.SqlClient" />
<add name="AzureWebJobsDashboard" connectionString="DefaultEndpointsProtocol=https;AccountName=ritual***;AccountKey=tQAP0gyMYKtWPJeIbsqk2iT2k69gyd1FwcyRf3+5Mc9b9EdYzpj0Dq8X2VHUmF*****"/>
<add name="AzureWebJobsStorage" connectionString="DefaultEndpointsProtocol=https;AccountName=ritual***;AccountKey=tQAP0gyMYKtWPJeIbsqk2iT2k69gyd1FwcyRf3+5Mc9b9EdYzpj0Dq8X2VHUmF*****" />
When i test locally (F5 Debugging) the webjob runs successfully and does the loop of the objects returned from the database. When i deploy this Azure the WebJob fails with the following error:

If i remove any of my database code and use just the basic Stub code my webjob will run successfully so i know that my connection strings (outside of the DB ones) are correct. My MVC web application also runs perfectly using the same connection strings
in Azure so i also know that they have also been configured.
I am now lost and need some guidance, so if someone is able to assist me that would be much appreciated.
Thanks
Ritual.

Can you try to log the connection string you are using in both cases to make sure they are the same?
Also can you share your site name, either directly or indirectly?
This will help us investigate.
Thanks,
Amit

A network-related or instance-specific error occurred while establishing a connection to SQL Server.

Dear all,
I know that this topic may be a bit old school; but it really make me mad as I tried all solutions i found and it still cant be resolved....please give a hand...
The situation is like this,my company divided different platform as a status of project, like DEV, SIT and UAT. I got a project that require me to upgrade an vs2003 project to vs2005. I upgraded it completely and
successfully, it works fine in development and UAT platform; EXCEPT, the SIT platform.
The situation is very strange that, once I move the source to SIT, it return the following error:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.
(provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)
but it never happen in either DEV or UAT platform and even do I copy the workable web.config from DEV or UAT platform to SIT, the error still here and unable to resolve it.
I search a lot in the internet by Google, but solution suggested are not suitable or fail in my case. Most answer suggest that "enable remote control", "check fire wall", "check server" etc......But as I can connect well the
DBServer in DEV and UAT properly, I dont think those are the cause(but still, I check them all, and all are enabled properly, except my firewall setting is OFF, so adding port is ignored).
After all the searching and testing, I believed and have reason to believe that, the cause is inside my web.config:
<appSettings>


<clear/>
<add key="Environment" value="UAT v1.31"/>
<add key="DBServer" value="DB_UAT"/>
<add key="cnBPSS.ConnectionString" value="data source=DB_UAT\BPSS;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096;pwd=theloginpwd"/>
<add key="UTBPSSConn.ConnectionString" value="data source=DB_UAT\BPSS;persist security info=False;user id=theloginid;workstation id=RP_UAT;packet size=4096;pwd=theloginpwd"/>
<add key="UTDSBDBConn.ConnectionString" value="workstation id=RP_UAT;packet size=4096;user id=theloginid;data source=DB_UAT\DSBDB;persist security info=False;password=theloginpwd"/>
<add key="cnDSBDB.ConnectionString" value="workstation id=RP_UAT;packet size=4096;user id=theloginid;data source=DB_UAT\DSBDB;persist security info=False;password=theloginpwd"/>
<add key="Timer1.Enabled" value="True"/>
<add key="Timer1.AutoReset" value="True"/>
<add key="cnbpss.ConnectionString" value="data source=DB_UAT\BPSS;password=theloginpwd;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096"/>
<add key="cnbpss1.ConnectionString" value="data source=DB_UAT\BPSS;password=theloginpwd;persist security info=True;user id=theloginid;workstation id=RP_UAT;packet size=4096"/>
</appSettings>
</configuration>
I know such kind of setting is old school; But due to this program runs for few years from tons of ppl...I dont dare to modify it unless I am very sure they are the cause.....
May I ask if anyone cna give me some advice and help in this issue please? I already tried for weeks and turning mad....Please I really need some help...
Many thanks.
Ksun Chan

that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 – Error Locating Server/Instance Specified) ”
How can we resolve the issue?
Thanks in advance.
Ram.

Also, rather than a SBS specific issue, it seems only relate to SQL server, you can also post it to SQL server forum so that SQL server experts there can provide more accurate solutions:

SSIS fails to load files from network when executed via SQL server Agent (SQL server 2008 R2 SP 2)

Hi All,
I have a simple SSIS package that reads a flat file and copies it into a SQL Server table.
When the flat fiel is on the C drive I have no problem runnign this package from SQL Server Agent, but as soon as I update the path to a network location the package only works when I run it manually, but fails when is executed via the SQL Server agent job.
The error says "cannot open the datafile", while the datafile location is valid.
Is this a kind of limitation of a SQL Server Agent that only local files are allowed to be processed?
Thanks,
Andrei
SSIS question

Hi All,

Connecting to the LOB system has failed. A network-related or instance-specific error occurred while establishing a connection to SQL Serve

Hi!
I'm using consume adapter service> sqlbinding > to connect to sql database in order to generate sql schemas.
I'm getting below error:
Connecting to the LOB system has failed.

Hi,
As suggested earlier this seems to be a DTC related issue. It can only occur if the DTC settings are not proper or if firewalls don't allow the default ports to communicate.
Check DTC settings on both SQL and BizTalk Box and also check if MSDTC service is up and running.
Go to Start
à Run
à (type in) Dcomcnfg. You should be inside Component Services MMC.
Expand Component Services
à Computers
à My Computer (right click)
à Properties
à MSDTC tab
à Security Configuration button.
Select the checkboxes as following :
Check the below article from Microsoft Support Team, they have listed all the errors which may come during setting up a new system. They also have your MSDTC error listed.
Resolving the issues you may face during BizTalk Runtime Configuration
