Disabling the Named Pipe Protocol in SQL Server
-
Hi All,
I need one help, In one of the interview the interviewer asked me if you are using web based application as a front end. What happened when we disable the named pipe? Will Application still work or will give any problem.
Thanks in advance!!

The application wont connect to database...
For remote connection you should enable both TCP\IP and NAMED PIPES

Hi
Ratheesh.K.Nair
May we use both TCP\IP and NAMED PIPES at the same time? if Yes please let us know how?
Thanks

i don't think that is true; SQL will simply use only the TCP/IP instead; disabling Named Pipes does not shut down the server or anything drastic like that;
TCP/IP is a little less chatty, but more prone to DNS errors; SQL by default gives priority to named pipe connections over TCP/IP.
take a look at this thread on the issue not too long ago; it's pretty well covered int he two pages:

--edit: i disabled mine as proof of concept; i can connect via my localhost website, via an application, and SSMS and Linqpad, all with no problem, even tho its now disabled; i stopped and started the service as well to be sure the settings were changed.

--help us help you! If you post a question, make sure you include a CREATE TABLE... statement and INSERT INTO... statement into that table to give the volunteers here representative data. with your description of the problem, we can provide a tested, verifiable solution to your question! asking the question the right way gets you a tested answer the fastest way possible! -

If you want to use Full Text indexing then you will need Named Pipes.

Interesting. Maybe the Microsoft documentation is wrong. See http://msdn.microsoft.com/en-us/library/ms345189.aspx for the reference

I would expect that it would use Shared Memory considering that all of the processes are running on the same machine.

Simply not true. I have worked with SQL Server 2005 farms that have a multitude of web servers connecting in to the databases and we had named pipes disabled in those instances.
Named pipes and TCP\IP both have networking advantages, TCP\IP is more resilient and generally preferred. There's reams of info on this if you look around

Would there be any performance benefit to disabling the Shared Memory Protocol?
We have a server that executes some rather large queries then pulls the data back to it via a linked server (I know, not such a good idea but that's what we're stuck with). This process has run fairly well for years but as of a few days ago became "extremely slow"...my gut feeling tells me we've just hit a tipping point in the sheer volume of data we're querying, then pulling back through the pipe.
I've read a bit online about the different types of protocols but am unclear if there's any performance boost to changing anything.
Any thoughts?

I don't think it will have an impact. This is a protocol and you were seeing memory pressure according to the waits if memory serves correctly.

Hi
I am an IT auditor and working on my first SQL server audit. One of my audit tests is to Verify that the Named Pipes protocol is disabled, unless there is a documented justification. My contact person told me “I disabled the Named Pipes in the SQL Native Client Config (Prod Server) but could not do so in the test and dev servers; it kept changing back to “Enabled”.”
When I followed up he told me "Given that we are not running multiple instances of SQL server on the same hardware, Names Pipes does not come into play. In other words, for the SQL Server configurations, Named Pipes does not pertain, regardless of these Named Pipe settings."
Does this sound reasonable to you SQL experts?
