Connecting to sqlserver using named pipe

I would like to connect to mssql (running on same PC as SQL Developer) using named pipes.
The host is listed in the Windows Service Manager as \\SX3102971\SIMSLOCAL
I have gone to the 'Oracle' tab, selected 'Advanced' and in the 'Custom JDBC URL'
entered
jdbc:jtds:sqlserver:\\SX3102971\SIMSLOCAL;namedPipe=true;user=<username>;password=<password>
where <username> and <password> are the true values.
I receive a message
Staus : Failure -Invalid connection information specified. Verify the URL format for the specified driver.
Can anyone advise on what may be wrong?
Also, can SQLDeveloper handle blank passwords?
The database is installed as part of a third party application, which sets the default dba logon with no password. SQL Developer states that a password is required. For the example above I have created my own log on.

Hi,
I managed to solve the problem. So don't worry about it.
For others who are looking for the solution...
- I have referred to the http://www.qint.de/joria/doc/jdbc/jtds.html.
- I have changed the URL element in IDEConnections.xml file located under where SQLDEVELOPER software is installed.
- The URL must look like the following ...
<URL>jdbc:jtds:sqlserver://\\.\;namedPipe=true;instance=<name of the database - without the server name>;</URL>
Hope this helps.
Regards
Raja

Export and Import using Named Pipes

Hai,
I need an clarification in export, import and compress of dumps using named pipes.I am using Oracle 9i RAC 9.2.0.4 in AIX 5.3. Every month i have to move list of tables from one database to another database after taking export dumps. The list of activities done by me at present are given below.
1. Taking export and gziping the dump file at the same time using named pipes.
2. Doing uncompress and import in the second database using named pipes.
We are doing compress for space constraints. Now my doubt is whether using named pipes, we can do both operation of import and compress of dump file at the same time. i.e, at the time of export itself , using named pipes, i need both import in the another database and compress the zip file. Is it possible?

Mxi includes on localhost using named pipes

hello all,
why does my addt "server side includes" didn't work when using localhost server using named pipes? my port is 8080 and i access the server using http//localhost:8080...
if i access mysql query browser im using "."(a dot)as my server host.
there is always a folder permission error but i can use php includes fine.
can anyone help in making the "server side includes" work?

There is no use for testing named pipes. As I said - it is an excellent method for IPC. It is slow and unscalable for networking, especially WANs.
A few minutes of googling this subject and doing some bit of research, would highlight this quite clearly.
BTW - if you think named pipes are better for tcp, then don't you think Oracle would have recommended its use? Heck, Oracle recommends using the RDS protocol for the RAC Interconnect. A protocol not widely known outside the HPC environment. So surely they would have sung the praises of more commonly known named pipes for tcp if it was any good?
Which again points to the fact that it ain't good and your wasting your time by trying to be "clever" and barking up the wrong tree.

How can I connect using named pipes ( NMP ) ?

Hi all,
I'd like to do compare the availablke protocol (TCP, IPC, BEQ, NMP ) connect to my db, but I'm not able to configure named pipes.

Connecting to SQLServer 2k named Instance

Hey guys, this time i need some URGENT help, i swapped from windows to linux platform and using CF9, when i create a DSN in windows using SERVER_NAME\INSTANCE_NAME for the Server field, filling user name and password with a Microsoft SQL Server native DSN works perfectly, but when i do this same thing on Linux i get this nasty error:
java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]The requested instance is either invalid or not running.
The root cause was that: java.sql.SQLNonTransientConnectionException: [Macromedia][SQLServer JDBC Driver]The requested instance is either invalid or not running.
So i tryed to create a connection using the "Other" as DSN type and filled out this info:
CF Data Source Name: Test
JDBC URL: jdbc:sqlserver://SERVER_NAME\INSTANCE_NAME:1433;DatabaseName=MyDatabase
Driver Class: com.microsoft.sqlserver.jdbc.SQLServerDriver
Driver Name: SQL Server JDBC
User name: myuser
Password: mypass
i get this error:
Connection verification failed for data source: test
com.microsoft.sqlserver.jdbc.SQLServerException: The TCP/IP connection to the host FULLSQL, port 1433 has failed. Error: "Connection refused. Verify the connection properties, check that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port, and that no firewall is blocking TCP connections to the port.".
This was done after downloading sqljdbc_3.0.1301.101_enu.tar.gz from microsoft's web site and placing the sqljdbc4.jar file inside the /opt/coldfusion9/runtime/lib directory.
So basically the first way to create the connection works on windows but not on linux, and the second way does not work in any place even tho it's supposed to be working...
Please send me some help ASAP, need this thing working BADLY!

Okay, just solved the mistery... i will NEVER connect since every time you install a new SQL Server instance THAT new instance will listen to a different port, in this case the default 1433 was working but for the first instance and i was trying to connect to a second one listening in some other port i can't remember ATM.
Thanx for that help ne way Adam....!

If your SQL Server is only configured for Windows authentication, you have no other way to change the configuration of the SQL Server to support the Mixed Mode (both Windows authentication and SQL Server authentication).

Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

This was originally posted in the SSIS Forum, but a member of the IS team suggested it be moved here. "Most recently I got this error (Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) so does this mean that SQL Server is still trying to use named pipes even if I only have TCP/IP enabled in SQL Server Configuration Manager?"
I'm having the same issue, and here's our scenario:
Installed SQL Server 2005 Developer Edition on a machine with WinXP SP2 and enabled remote connections over TCP/IP
Installed SQL Server 2005 Standard Edition on a machine with Win2003 SP1 (remote connections over TCP/IP enabled by default)
Attempted to 'Copy Database' from Developer Edition TO Standard Edition using 'Detach and Attach' method and recieved the error on the Win2003 machine: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
Attempted to 'Copy Database' from Developer Edition TO Standard Edition using 'SQL Management Objects' method and recieved the error on the Win2003 machine: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server
Reinstalled Standard Edition on the Win2003 SP1 machine
Checked all the settings on both machines several times, restarted services etc., and read every post I could find referencing the error.
Same error
Lost my last hair
Thanks in advance,
Steve

Nan,
Before I get on with this post - thank you for your reply.
The XPSP2 machine actually had the firewall disabled, and I verified that it could accept connections on the the associated ports with the Shields Up utility. I tested this on both machines.
I can connect to the server from the XPSP2 machine, Import / Export, manage, view logs, and do everything EXCEPT get the Copy Database package to run. SQL Server Agent always fails on the last step with the following error:

Named pipes provider : could not open a connection to a SqL server . . . . .

Hey all, i need help
I have a job which was running quite peacefully for the last EVER, but since last Saturday it keeps failing and then run successfully and then fails. . . . .and gives me the below error.

I have already tested the linked server connection between those servers and its fine. And what is weird is that when i run the job manually it runs successfully.
Any ideas?

Hi,
How often does the job run? Does the query fail intermittently?
I suggest you check the following configuration on both servers:
1. In SQL Server Configuration Manager, expand SQL Server Native Client Configuration, right-click
Client Protocols, and then click Properties. What’s the order of protocol?
2. Check if the default port of TCP/IP is set to 1433.
By default, the top protocol is to use TCP/IP and then Named Pipes. There are two possible situations:
1. Connection fails and client protocol is using TCP/IP 1433.
When server A remotes to server B, it will use TCP/IP connection. If it encounters some issue during connecting (such as network issues), it will use Named Pipes instead. If the Name Pipes 445 still fails, thus the above error message will
be thrown out. It will use Name Pipes afterwards until the SQL Server service is restarted.
2. The port number is not 1433.
However, the remote machine is listening 1433. Then, the linked server will trying to use TCP/IP first. Because of the port error, it will change to Name Pipes.
Thanks.

Named Pipes using mkfifo and Cocoa

I have a C++ application that uses named pipes by calling mkfifo and I would like to use them to connect to a Cocoa app. I have taken a look at NSPipe but there isn't an option to connect to a named pipe. Does anyone know how to connect NSPipes or something else I can tie into the NSNotificationCenter that can talk to named pipes?
Thank you for your time,
Tom

-(void)SomeFunc
const char * path = "/tmp/tom21";
if(mkfifo(path, 0666) == -1 && errno !=EEXIST){
NSLog(@"Unable to open the named pipe %c", path);
NSFileHandle * filehandleForReading;
int fd = open(path, O_RDWR | O_NDELAY);
filehandleForReading = [[NSFileHandle alloc] initWithFileDescriptor:fd closeOnDealloc: YES];
NSNotificationCenter *nc;
nc = [NSNotificationCenter defaultCenter];
[nc removeObserver:self];
[nc addObserver:self
selector:@selector(dataReady:)
name:NSFileHandleReadCompletionNotification
object:filehandleForReading];
[filehandleForReading readInBackgroundAndNotify];
And then here is the func that gets called by the Notification server
- (void)dataReady:(NSNotification *)n
NSData *d;
d = [[n userInfo] valueForKey:NSFileHandleNotificationDataItem];
NSLog(@"dataReady:%d bytes", [d length]);
if ([d length]) {
[self appendData:d];
//Tell the fileHandler to asychronusly report back
[filehandleForReading readInBackgroundAndNotify];
}

Switching from Named Pipes to Tcp/Ip sockets : can I use the same DB or will I loose my data?

Hi,
we use MDT 2013 in conjunction with a local SQL Express 2012 database. I configured MDT to use Named Pipes but I want to switch to TCP/IP sockets. Is it possible to change that Network Library for an existing database? Am I going to loose the contents of
the existing db? Thanks for your insights.
Paul

Just did a testrun with a test deployment share. Made a db with Named Pipes, filled in some values. Created a new db and I was able to choose between some existing databases. I chose the test db and yes all the values are in it.
Next I tried it with my main db and indeed nothing is lost. Pfjew.

Javascript and Named Pipes

I am trying to write a script for AE and I want to use named pipes to communicate. My pipe server is working fine and it's functioning great in .NET when both sides are .NET programs.
When I connect my AE javascript to the pipe as the client, the server side sees the connection, but the javascript side immediately closes it. The server reports that the pipe is broken. For the record, the server is set up for only one client and the .NET client program has been shut down.
I am just getting started with this, so the code is only a few lines:
var f = new File("\\\\.\\pipe\\MYPIPE");
b=f.open ("r");
$.writeln (b);
$.writeln (b);
What's interesting is that the value of "b" is immediately false, and the error is simply "I/O error".
Anyone have any experience with this?
Thanks in advance.

At this point we do not have specific plans for adding shared memory or named pipes support but we appreciate your feedback, and will take it into consideration when planning future release(s).

Connection to sqlserver

what folder does the jar file for the sqlserver jdbc drivers go? The documentation says [JRE_HOME]/lib, but the Oracle drivers are in oc4j\jdbc\lib folder.

Hi JD;
I didn't install SQLServer 2000/2005 BUT what I installed in my laptop was small version of SQLServer called "SQLServer Express" same as Oracle XE.
This is what I did to accomplish the task on SQLServer Express:
1) Downloaded latest version of SQLServer JDBC driver from Microsoft website
2) Set up login connection to SQLServer using "SQLServer Authenication" NOT windows.
3) Create AdventureWorks or Nortwind schema downloaded from Microsoft website.
4) Create a user thru SQLServer Management Studio is like ORACLE DB console.
5) test the connection from SQLServer
6) test the connextion using XMLP JDBC connection
Also to make more spicier I did the connection to MS-ACCESS using ODBC:JDBC driver BUT the Query Builder didn't work but my small sqlscript worked for a demo to clients.
Here are the link to achieve:

WCF based named pipe naming convention.

I found the following msdn article http://blogs.msdn.com/b/rodneyviana/archive/2011/03/22/named-pipes-in-wcf-are-named-but-not-by-you-and-how-to-find-the-actual-windows-object-name.aspx
which states how to acquire the memory mapped file name in order to infer the actual pipe name, however my results are not proving successful. Further, the screen caps that the author took don't jive with my results either. I do not reveal the mmap file name
but the actual named pipe (obviously) when listing pipes.
Does anyone know how to infer the name of the pipe accepting input? I am required to provide access to code written in Python which is why I need the actual pipe name.
Thanks!

Long answer in "teaching to fish" style of how to actually get the pipe name:
I attached WinDbg to a program hosting a WCF service using named pipe transports and ran the following commands:
.loadby sos clr
!DumpHeap -type Pipe
I clicked through several of the objects and ultimately found this one whose relevant properties are also dumped below:

I then ran !gcroot 0000004409939f28 to see where it came from:
            -> 000000440990aba0 System.ServiceModel.Dispatcher.ChannelDispatcher
            -> 0000004409901868 System.ServiceModel.Channels.NamedPipeDuplexChannelListener
            -> 0000004409939ee8 System.Action
            -> 0000004409921ff8 System.ServiceModel.Channels.ExclusiveNamedPipeTransportManager
            -> 000000440993a0d8 System.ServiceModel.Channels.ConnectionDemuxer
            -> 000000440993a1f8 System.ServiceModel.Channels.ConnectionAcceptor
            -> 0000004409939fb0 System.ServiceModel.Channels.BufferedConnectionListener
            -> 0000004409939f28 System.ServiceModel.Channels.PipeConnectionListener
Running !gcroot 000000440990aba0 System.ServiceModel.Dispatcher.ChannelDispatcher shows that one of the ways it is bound is through the class in the program that I used to create the service host(WCFPS from
my blog post here):
    -> 00000044097e1220 WCFPSExecutor.WCFPS
    -> 00000044097e6ae0 System.ServiceModel.ServiceHost
    -> 000000440981d960 System.ServiceModel.Dispatcher.ChannelDispatcherCollection
    -> 000000440981d988 System.Collections.Generic.List`1[[System.ServiceModel.Dispatcher.ChannelDispatcherBase, System.ServiceModel]]
    -> 000000440990d0f8 System.Object[]
    -> 000000440990aba0 System.ServiceModel.Dispatcher.ChannelDispatcher
So now that I knew that, I did a !do on the ServiceHost object and found that the ChannelDispatcherCollection was contained in a member named channelDispatchers. Doing that again on that member, I saw that the collection came from a member named items.
One more time, and now I knew that System.Object[] came from items. Finally, the first element in that array was the ChannelDispatcher. At that point, I subsequently repeated the process of off ChannelDispatcher to get to PipeConnectionListener
and ultimately PipeSharedMemory which resulted in the following path to getting the pipe name:
(ServiceHost that the program opened).channelDispathers.items.items ->For each ChannelDispatcher until PipeSharedMemoryIsFound -> (ChannelDispatcher).listener.messageReceivedCallback.target.connectionDemuxer.acceptor.listener.connectionListener.sharedMemory
One will have to use System.Reflection (or something even more complicated) to access all of that at runtime, but there's a string member named pipeName at that point with an actual name, and a fileMapping member whose handle member contains a handle that
you can use to get/verify the pipe name as well with
GetFileInformationByHandleEx.

Named Pipes Error Recovery

I have a program which uses named pipes to communicate with a (third party) named pipe server. I call CreateFile to open the pipe, then Readfile and Writefile to read and write data. If I get an error, e.g. due to a network fault, I call CancelIo, then
CloseHandle to close the pipe, then Createfile to re-open it. I have tested this by unplugging/replugging the network cable. However, on site in a 'real' environment, I have had a couple of occasions where I have received a 'ERROR_NETNAME_DELETED' from the
pipe I/O, and when I close the handle and call CreateFile to try and recover, I get the error 'ERROR_SEM_TIMEOUT' from the CreateFile call. Can anyone think why this might be? I guess a difference between my testing and what is happening 'for real' might be
that my testing involved disconnecting the network cable, whereas the 'live' incident may have been just a temporary glitch on the network.

Yes, unpluggin a network cable is entirely different from communication glitches, lost packets and firewall issues.
One of the big reasons is that unplugged network cables are detected by windows, and the port is shut down. In network management in control panel you'll see the red cross. resources associated with that port will be freed, and communications will be aborted.
However, if the network port stays up, Windows will not know that anything went wrong. It still sees an active port, so it will just keep waiting for data to arrive. Communications that were in process may still be waiting when you retry them, so you have
to be careful with the error handling, and verify that a) you handle all problems, and b) you cancel all necessary things.
If you want to test such scenarios, you could play with the firewall on the target computer to simulate lost packets and timeouts.

Unload/load to/from named pipe

Hi,
I want to unload data to a named pipe and
load data from that pipe.
Is there any way for this.
Kind Regards

Some KMs are using named pipe.
take this KM as example : IKM SQL to Teradata (piped TPUMP-FAST-MULTILOAD)
This only work for unix pipe! not for window...
