Tcp Traffic
Jul 20, 2005
Hi,
The application setup is: Access frontend + ODBC (TCP/IP) + MSSQL7
Few days ago i was informed that the app generates high network
traffic. Thus
i started to look for some savings.
I found out (sniffer) that even if the client is idle every 30sek. a
TCP packet comes from client to server, then answer goes back. The
packet seems to be empty (TCP data is 1 byte: 0x00), the answer is
empty as well. Seems like kind of watchdog. And it does not seem to be
related to ODBC refresh and any other option possible for setup in
Access client (I set those settings to different that 30sek. values,
and 30 sek. traffic still exists).
Does anybody know what those packets are for, what module is
responsible for them and how to change interval?
My best regards for anybody reading this post,
Mirek

What sort of traffic would be going on between the machine I am on Enterprise Manager and have a server registered (my local machine) to the actual SQL server? I haven't logged onto the actual SQL machine I only have it listed as a registered server and it's sitting there in the list with it's little green "started" icon.
I'm asking because i'm getting accused for a server going down. I opened my EM around the same time as this SQL server went down and some network people see my machine talking to the SQL server at the same time.
Any ideas? Thanks...

I am having a problem and this may be more of a network issue bandwidth issue: When I ping from one of my dataservers to another dataserver it takes 10ms. However, if I ping from a fileserver to a dataserver it takes 1ms. Also, if I ping from a Citrix server to another Citrix server or one of the data servers, it also takes 10ms. What are my options?

Can anyone HELP!!
I have a system set up with 2 servers, the master server replicating the data to the backup server. Each server has two network cards, 1 which links directly to the other server.
The problem is the replication is being routed round the network making the direct link useless.
How can this be ammended!!
They are both logging into the same primary controler.
I am open to sugestions

OK, I'm troubleshooting a performance issue on one of our production servers, but I really can't t-shoot and tweak in real-time, so I took a snapshot of "a day in the life of" my production server using the profiler.
I want to run the sql commands I collected on another server I set up identical to production, and play around there.
Does anyone know of a good tool to "replay" those captured commands onot another server?

We are using the following configuration:
2 stand alone Windows 2003 servers 64 bit.
Each have two Gig Network cards configured with different IP addresses.
Each running multiple instances of SQL Server 64.
I am trying to set up a mirror where mirroring traffic between servers will be dedicated to a secondary IP address on the second NIC.
I am also trying to avoid Windows authentication.
Interesting enough: Security Configuration screen suggesting you to use fully qualified TCP addresses and, at the same time, does not give you such an option...
Would someone please point me in the right direction?
Thank you.

I have a database of details of users that visit my site. Among other things, it saves the ipaddress and the date/time of the visit. I would like to be able to determine the unique visitors (by ipaddress) that i have on any given day. The problem though is that the data is saved as a date and a time, thus when I try and determine the unique visitors, since they are all a different time, MSSQL thinks they are all unique visitors. Any ideas how I can get around this without acctually modifying the data in the underlying table?

Hello, we are trying to find a way to send all SQL traffic from multiple machines in a DMZ trough only one point. This way the firewall doesn't need to be opened to each and every machine.
This may be a simple question but I have never done it before. Any recommendations?
Thanks in advance.

Query(a report) to list the technicians/traffic controllers separately with following details.
EmployeeId,Name,Salary,Address,UnionId, and the most recent medical examination date for traffic controllers
Employee (EmployeeId(p),Name,Salary,Tpye).
MedicalExamination(MedicalNo(p),EmployeeId,MedicalDate)
EmployeeUnion(EmployeeId(p),UnionId(p))
"Type" field in Employee table tells whether its a technicians or a traffic controller.only traffic controllers has medical examination.

I looking for a way of measuring how many MB of outbound SQL data is being transferred during the course of a day from an OLTP instance. Data is pulled from this server by a DW in the same domain and adhoc via a linked server. I'm looking at perfmon but nit sure if this is the correct tool and if so which counters to use. I'm looking for the total MB/GB over the period not the MB per sec.

Would anyone have a suggestion on how to setup a partner to partner NIC configuration for heartbeats/mirroring traffic? I've been told this is the recommended setup but have not found much on how to do it. We currently have a teamed NIC config for redundancy, but would like to have a separate set of NICs on each partner so that mirroring traffic is not interrupted by any regular network traffic.
We also have a witness running in full safety mode. Does this mean partnerA and partner B both need NICs with a crossover cable between them AND is it recommended for the witness to also have extra NICs to both partnerA and partnerB (w/ crossover cables)?
Any suggestions/help/links on properly configuring this would be appreciated.

Ive read a few docs and i have some doubts about the implementation i ll make.
I will setup a FCI between ServerA and ServerB. So my databases will be running on server A or on ServerB. they will be replicated using AllwaysON to ServerC.
Because ill use a diferent vlan for AllwaysON replication iam having some doubts on how can i set the endpoints...
For example.
I ll have the following ips configured for AllwaysON replication on Server A, Server B and Server C 10.10.240.1/10.10.240.2/10.10.240.3
Database teste will be running on serverA. the endpoint configured will be 10.10.240.1 but when database fails over to Server B (using FCI) the ip configured there will be 10.10.240.2... so AO replication will stop working.
I tough on associating a virtual ip to the AllwaysON cluster resource but Microsoft doesn't recommend to alter AllwaysON cluster resource.
How can i implement this configuration?

I have been told that I need to setup a crossover cable between a Server that has an application to have a dedicated NIC (using a crossover cable) to a server that has SQL 2005 Sp2 for fast access. How is htis done as far as SQL Properties, and NIC Settings, How do I make sure SQL will transmit using that 2nd NIC?
Thanks,
David Baur

We have a Customized share point application with Very minimal data usage and we have used only 5 to 6 lists and libraries only in the share point.
Configuration is
Clients -- fire wall --- Load Balancer ---- WF1 and WF2 --- SQL DB
ROUTING IS VIA FIRE WALL.
SUDDENLY THE SITE GOT DEAD SLOW AND UNABLE TO TRACE THE PROBLEM AS EVERY THING LOOKS FINE.
Checked with the firewall Team and they stated its fine from their end & even we have verified the counters, CPU, Memory & Page life expectancy, buffer counters all looks good and even we do not have huge data in the database. We have only 50 concurrent users are working...
