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).

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?

What should be started and enabled in SQL express 2008 R2? Shared memory, TCP/IP , named pipes, VIA

I copied my Visual Studio 2008 projects to a new computer and am having trouble getting the database to attach to my website to continue with it.
I uninstalled SQL 2005 express and installed SQL 2008 R2 Express.
When I looked in the SQL Server configuration manager, I wasn't sure what should be running and what should be stopped and what protocols should be enabled, etc so I started everything and enabled everything.
However, the SQL Server Agent will not start. Maybe I did something wrong by enabling everything. I have everything to start automatically, and all enabled:
SQL Native Client: I right clicked and opened and under client protocols, have enabled all: Shared memory, TCP/IP , named pipes, VIA
and under SQL Server Network Configuration, I opened that and under there is listed protocols for SQLEXPRESS AND I enabled same things: Shared memory, TCP/IP , named pipes, VIA
When I could not start the SQL Server Agent before from the SQL Server configuration mgr. I went into services and started it that way and it did start. But since I have rebooted, it will not start that way either and I now get this message: Windows could
not start the SQL Server Agent(SQLEXPRESS) Service on local computer. Error 1067
I'm just trying to get my visual studio project working again. Would appreciate any help. Maybe I should uninstall SQL and reinstall 2005??

Windows could not start the SQL Server Agent(SQLEXPRESS) Service on local computer.
As the others already wrote, with SQL Server Express in Version 2008 the "SQL Server Agent" will be installed, but it's not a Feature of the Express Edition and therefore you can't start & use it.
In SQL Server 2005 Express the Agent was completly missing (not installed), therefore you haven't this "issue" before.

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;

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];

Named Pipes Provider: Could not open a connection to SQL Server

We are running into an error on a SQL request from SQL-IDA to the SQL-IDB server. Both servers are on Windows 2005 with MS SQL Server 2003 SP3.
OLE DB provider "SQL-IDA" for linked server "SQL-IDB" returned message "Login timeout
expired".
OLE DB provider "SQL-IDA" for linked server "SQL-IDB" returned message "An error has
occurred while establishing a connection to the server. When connecting to SQL Server 2005,
this failure may be caused by the fact that under the default settings SQL Server does not
allow remote connections.".
Msg 53, Level 16, State 1, Line 0
Named Pipes Provider: Could not open a connection to SQL Server [53].
It seems to suggest that SQL-IDA cannot find the network path to SQL-IDB. We've followed the steps in this article http://support.microsoft.com/default.aspx?scid=kb;EN-US;914277 but it did not resolve our issue. Is it possible that the MSDTC dynamic port range
should be set to a specific range on both servers?
Any help is greatly appreciated.
Albert

Hi Albert,
Can you try to use the SQL Server Management Studio on server ‘SQL-IDA’ to connect to the instance on server ‘SQL-IDB’ to see if it works or not?
There are possible reasons to error 53:
a) typo in the server name, or using "/" rather than "\" between server name and instance name, e.g. "myserver/myinst" is not correct.
b) name resolution to the server name is not correct, "ping -a yourserver" would tell if that's the case
c) The server machine is firewall'ed and file sharing is not in the exception list. You need put "File and Printer Sharing" in exception.

Named Pipes provider, error:40 could not open a connection to sql server. Only happens on one of the front end SRS servers

when testing a datasource connection I get the following error.
Named Pipes provider, error:40 could not open a connection to sql server.
I've read all the posts on this and nothing works. This is a scale out deployment and the connection
works from the other server I have setup with SRS that is connected to the same backend SRS databases. It just doesn't work from one of the SRS front ends. I'm at a loss.. please help

Enable both named pipe and TCP communications.
Make sure client is using the same (named) pipe name as server for connection.

Reporting Services 2008 R2 configuration error: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server

Hi, I am using SQL Server 2008 R2 and on one of our dev boxes I am trying to setup ReportServer using ReportingServices Configuration manager. This is was installed longtime back and during installation they created a service account for reporting services.
When I try to configure the service account I do not get the service account created during the installation in the pull down and if I were to use something different I get this "Named Pipes Provider, error: 40 - Could not open a connection to SQL Server"

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

Hi,
I'm encountering an issue with "Named Pipes Provider, error: 40 windows" and am having problems determining how to fix it due to the environment I'm using. I have two SQL Servers installed on two separate Win2K3 Server boxes, one is SQL Server 2000 and the other is SQL Server 2005. The SQL Server 2000 contains the actual application data. The 2005 database is used only for Reporting Services. I've set up the reports on SSRS such that their datasources hit the 2000 server. This is using SQL Server authentication.
When testing the reports via SSRS (in Visual Studio 2005), the connection to the data works and the reports are generated fine. When I deploy them to the reporting server and launch IE to test locally (still on the 2005 box), I get this "Named Pipes Provider, error 40" issue. I made sure that Named Pipes and TCP were enabled and the port set at 1433 (to match that on the 2000 box).
Now I changed the datasource's authentication from SQL Server to Windows authentication. I tested this in SSRS and this works too. When I redeployed the reports with this authentication change, testing the reports via IE locally (on the 2005 box) worked. Great. Now when I open IE on an external box, i.e. on the 2000 box, and try to test the reports, I get this same error 40 issue. I've been through a few threads describing the error 40, fiddling around with the SQL Server configuration as well as SSRS, to no avail. I have a feeling this error 40 issue has to due with permissions/authentication between the SQL Server boxes but I can't really be sure. Anyone have any ideas on how to troubleshoot my situation. Thanks.

Named Pipes Provider, error: 40 - Could not open a connection to SQL Server :
I. Incorrect connection string, such as using SqlExpress.
Check out: http://forums.microsoft.com/TechNet/ShowPost.aspx?PostID=558456&SiteID=17
https://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1245564&SiteID=1
The typical error when dealing with Express includes:
a. User is not aware of SqlExpress was installed as a named instance, consequently, in his/her connection string, he/she only specify ".","localhost" etc instead of ".\SqlExpress" or "<machinename>\Sqlexpress".
b. Np was disabld by default after installing SqlExpress.
c. If Sqlexpress was installed on the remote box, you need to enable remote connection for Express.
Please read the following blog for best practice of connecting to SqlExpress.
http://blogs.msdn.com/sql_protocols/archive/2006/03/23/558651.aspx
II. Named Pipes(NP) was not enabled on the SQL instance.
Check out: http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=136253&SiteID=1
Oppose to SQL 2000 which turn on all protocols, SQL 2005 SKUs turn off NP by default. So, when you see this error, please check:
1) Go to SQL Server Configuration Manager, See Server has NP enabled.
2) %windir%\program files\microsoft sql server\mssql.1\mssql\log, notepad ERRORLOG, see whether Server is listening on NP. You should see "Server named pipe provider is ready to accept connection on [ \\.\pipe\sql\query ] or [\\.\pipe\mssql$<InstanceName>\sql\query]"
3) Notice that "sql\query" is the default pipe name, so you need to know server is listening on which pipe name. eg: if you specify server pipe name is "sql\query1", then you would see in the errorlog that server listening on [ \\.\pipe\sql\query1 ], and go to SQL Server Configuration Manager, click client Named Pipe properties, see whether the pipe name is same with the one server listening on.
4) If you are using SQL Native Client ODBC/OLEDB provider({SQL Native Client} or SQLNCLI), go to SQL Configuration Manager, click client protocols, make sure NP and TCP are both enabled. Right click properties of NP, make sure client is using the same pipe name as server for connection.
5) If you are using MDAC ODBC/OLEDB({SQL Server} or SQLOLEDB) provider, in command line, launch "cliconfg.exe" and make sure NP enabled and right pipe name specified.
III. Remote connection was not enabled.

If you are making a remote connection, namely, your target SQL Server is on the different box as client application, you might need to check whether:
a. "File and Printer Sharing" was opened in Firewall exception list.
b. Please see the blog for enabling remote connection for express and troubleshooting tips of remote connection.

a. use "sc query mssqlserver" for default instance or "sc query mssql$<instancename>" to make sure SQL Server was started. Sometimes, reseason behind the broken of your client application w/ this error:40 might be SQL server restarted and failed, so, it'd better for you to double check.
b. User specified wrong server in their connection string, as described in the forum discussion, "MSSQLSERVER" is an invalid instance name. Remember, when you connect to default instance, <machinename> could be best representitive for the instance, when you connect to a named instance such as sqlexpress, you should specify <machinename>\<instancename> as data source in your connection string.
V. Other reasons such as incorrect security context.

Such error also occured during user operation such as moving database or db mirroring or cluster, any DB OP that might invovle different sql instances, namely, the destination database is located in another sql instance and user is not aware of the state of the destination. I recommend you first isolate whether this fail is during connection stage or data operation stage.
a. During data operation, you are normally asked to type in the destination server name whether it is default to "(local)" or another server "<remotemachinename>". So, remember the exact string that represent the target instance, then when the error repros, open command line, use "sqlcmd -S<representitive> -E" ,see what happens, if the connection fail, please follow up above I - IV troubleshooting lists. otherwise continue.
b. If you can make basic conection, but still face the error, then there must be something that server reject the connection or client close the connection for some reason.
VI. Please try basic connectivity tests between the two mahcines you are working on. One simple way to verifty connectivity is to use command line tools, such as osql.exe. For example, osql -E -Stcpervername\instancename. If it connects cross-machine successfully, please also verify that your connection string in your scenario is correct.
Here are some blogs which could be helpful: just follow the basic connectivity troubleshooting guidelines on the SQL Protocols blog, see:

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.

SQL*Loader Named Pipe Load Thread goes to 0

Hi,
Running SQL*Loader 10.2.0.1.0 on XP pro against 10g EE 10.2.0.2.0 Production, RAC.
Control file:
OPTIONS ( MULTITHREADING=TRUE, DIRECT=TRUE, ROWS=5000000, COLUMNARRAYROWS = 200000 )
UNRECOVERABLE
LOAD DATA
--INFILE 'C:\Program Files\Delta Data Software, Inc\DDS Twenty Two C\SQL_LOADER\LDR.DAT' "fix 427"

INSERT
INTO TABLE "TDW999999"
Data File is 1 million row text file, 427 byte per line
Problem:
When calling SqlLdr directly against the data file, the import runs in 1:47(min\secs).
Total stream buffers loaded by SQL*Loader main thread: 408
Total stream buffers loaded by SQL*Loader load thread: 2036
However, when I pipe the same data to SqlLdr via a simple c# application with a named pipe, it takes 5:56(mins\secs).
Pipe Base Load:
Total stream buffers loaded by SQL*Loader main thread: 104249
Total stream buffers loaded by SQL*Loader load thread: 0
It looks like SqlLdr can not go parallel when input is from a named pipe.
Any Ideas on how I can get my load thread count back up when using pipes ?
Thanks

Hi,
According to http://www.mcse.ms/archive27-2006-1-2068094.html you can do the following (substitute your c# program for 'type load.dat'):
>
type load.dat|sqlldr control=load.ctl userid=user/password data=\"-\"
Alternative (for both , unix and windows)- infile syntax:
load data
infile "-"
into table...
Metalink note 191043.1 may be interesting for you as well.
Does the performance then improve?

SQL Server Agent - [165] ODBC Error: 0, Named Pipes Provider: Could not open a connection to SQL Server [2]. [SQLSTATE 08001]

Hi,
I keep receiving the error below in the SQL Server Agent Error Log;
[165] ODBC Error: 0, Named Pipes Provider: Could not open a connection to SQL Server [2]. [SQLSTATE 08001]
It is occurring approximately 20 times an hour and i cannot link it to any job failures. All jobs on the same SQL instance are working.
The server is a clustered server and there are no errors occuring in the SQL Server error log at the same time. I have attempted to trace using profiler looking for errors and warnings but anything that does occur doesn't seem to correspond to the reported
times of the errors within the sql agent error log.
Please could someone point me where to look next?
Many thanks.

Please may I add that this is on a SQL Server 2008 R2 Enterprise edition patched to 10.50.1600.
Nah, that server is not patched at all, because 10.50.1600 is the RTM version. Find Service Pack 2 and install at the next maintenance window, after having performed tests according to your local policy.
It is not going to resolve your particular problem though.
It seems like you have a job that attempts to a connect to s server that is down or non-existing. The job may be configured to return success also on failures. I would check if there are jobs that target other servers.

Named Pipes Provider, error: 40 on workgroup workstations

I am having issues with a vendor supplied application. It generates an error when run from workstations that are not part of an Active Directory domain. The error is “provider: Named Pipes Provider, error: 40 –
Could not open a connection to SQL Server)”. It runs as expected when ran from a workstation that is a member of the domain. Obviously adding the workstation to the domain is a solution. However, because of concern of what might break this is not our preferred
solution.
The database is SQL Server 2008 on a 2008R2 system that is a member server of a domain. The systems that are having the error are workgroup systems running Windows 7. Except for the final step, I have pretty much
eliminated the other possibilities in Steps to troubleshoot SQL connectivity issues.
That, and the fact that the application successfully runs from a workstation that is a member of the domain lead me to believe it is an account/authentication issue on the workstation.
From what I have determined SQL authentication is required in this scenario and I have confirmed that the database server is configured for Windows and SQL Server authentication. I have also examined
the configuration file the application uses. It contains the user name and password for the account. Are these credentials not used to establish a connection?
The only thing I can think of, which I haven’t tested because 1) it is a production system and 2) it is a vendor supplied application, is the application needs to be run under a local workstation
account with the same credentials as the SQL Server account.
Could this be the case or is there something else I should be look at?
Thanks in advance.

Thanks for your response. I had posted a reply earlier but for some reason it doesn't appear to have uploaded.
The server name in the connection string is ntsrv12.xxx.yyy.edu. I am able to ping that name and ntsrv12 as well from workstations where the application fails.
I have some information from some additional testing I have done. Using my workstation, which is a domain member, I can successfully run the application when logged on with my domain user account.
However, if I logon with a local account the application fails with the error described above.
I have also been able to match Audit Failures in the SQL Server event log with failed attempts to run the application. There is a two error sequence that appears several times for 15 seconds until the application times out and displays the error message.
I have listed the errors below but certainly the application appears to see the server. Any ideas on what to check next?
Thank you.

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 Provider: Could not open a connection to SQL Server [2]

Hi
I'm a complete sql/asp.net newbie and want to try this tutorial:
http://beta.asp.net/GuidedTour/
First I installed:
Visual Web Developer 2005 Express Edition Beta 2
systemsettings\software shows the "sql server 2005 express edition ctp (sqlexpress)" installed
mmc\service shows me the SQL Server (SQLExpress) is running
Following the guided tour I use the commandline, type cmd, and type in the commandbox:
"C:\Program Files\Microsoft SQL Server\90\Tools\binn\SQLCMD90" -S "localhost\SqlExpress"
Instead of localhost I also tried computername.smallbusiness.local (thats my fully domain name).
However I always receive the error:
Named Pipes Provider: Could not open a connection to SQL Server [2]
Thank you very much for all your help

Typically I have found problems with connection strings as one of a few things:
1. Your instance is named different than the default. I labeled mine BrettSQLServer instead of the regular instance.
2. Your default storage of the your database has a user the system does not like and won't give it access.
3. You have ports blocked that SQL Server is trying to access.
1. Your instance should show up under 'SQL Server Configuration Manager'. Start>MS SQL Server 2008 > Configuration Tools> SQL Server Configuration Manager. You should see a left view panel where you can click 'SQL Server Services'. This
will show on the right all of your SQL services that are running. The most important one is SQL Server({Your SQL Server Name}). You will see column headers's displaying: "Name, State, Start Mode, Log on as, ProcessID" by default. If
you don't see a version of this you may have no installed SQL server properly and gotten SQL management studio but not the server. If you have the server and it's off or not running that is another problem. If your "LOG On AS" is a service account
is "NT ...." or something besides "Local System" that may be a problem. Without getting into the symantecs of protection suffice to say you log in with less than system, yes you are more secure but some built in functions for connections may not work.
2. Going off of rights of your 'Log On As' I WOULD USE 'System' NOT "NT Authority....". The reason is that you can access less things with 'NT Authority....' but yes you are more secure for that reason. If you are just trying to connect at home
to test non secure things I don't see the harm. If you are setting up a database for a multinational corporation than, Yes I would use a more secure account. If you need to change it while still in SQL Server Confi Manager: Right Click> SQL
Server(Your Version) > On 'Log On' tab > Choose drop down for 'Built-in Account' select 'Local System'. As extra steps make sure by some strange reason your database locales have this user by default(They should). MS likes to install database
as default to: C:\Program Files\Microsoft SQL Server\MSSQL10.{instanceName}\MSSQL. If you go to this location by going: right click>Properties>Security Tab .. and you fail to see your user that SQL server is defined as you may have lots of
issues.
3. Turn off Windows Firewall during SQL installation. If you are scared of being attacked during this down window, disconnect your NIC and reconnect later. I have not added a port manually in a while but it is simply easier to just
turn off your firewall during install. Having your TCP/IP connection from SQL Server blocked is kind of bad if you need to connect to it that way later.
Problems most commonly encountered with SQL Server by users I have seen and I myself encountered a lot with full blown SQL Server Enterprise as well as Express versions of SQL:
Connection string DO not work for BIDS, ADO.net, Linq, etc...
Once you follow steps above just go {ComputerName}\{SQL Server Instance} as your connection name. That mostly always works. As a preliminary test you should install SQL Management Studio first before doing connection strings for a basic test
that it can access your server. When you first boot it up and click 'New Database Engine Query' it will display Server Type: "Database Engine" and a blank field or autopopulated field for 'Servername'. The {ComputerName}\{SQL Server Instance} almost
always works. If it works and you can connect, you know that you have access, if you don't start there first before getting into connection strings through .NET languages. I suggest just adding an easy alias, my local SQL box is simply called
'Brett'. Go again back to SQL Server Configuration Manager. On the left side click 'SQL Native Client ...' > 'Aliases' > New > type in whatever you want. Go back to the left pane click on 'SQL Server Services' ensure the service
'SQL Server Browser' is running and set to run automatic. Have fun accessing SQL Server with your alias.
Help I can't get FileStream to work and I ran 'spconfigure' in SQL and it still doesn't work.
Kind of annoying that more sites don't list that it is entirely in the Configuration manager and has zilch to do with setting the option if the config has it off. I am not a master of the sp_configure TSQL access method but I know during installs turning
it on fails to REALLY turn it on. Once again go to SQL Config Manger > SQL Server Services > Right click your instance > Select FILESTREAM tab > enable both check boxes. Restart SQL Server. Install Adventureworks 2008 and whatever
else failed due to filestream access levels.
