Xp_cmdshell - Need To Execute External Program Asynchonous
Oct 21, 2004
hi,
i need to start an external program (vb.net) from within a trigger. via xp_cmdshell everything works fine except that the execution of the trigger waits for the vb-program to finish.
now i tried a workaround with a "starter application" which only calls the vb.net program (asynchronous) an ends.
this works fine from a dos prompt (command prompt returns immediately and vb.net task is running). but when i call the starter app from the trigger with xp_cmdshell, the behavior is the same as before: execution does not continue until the vb.net task ends.
any other ideas that could solve my problem? submitting an agent-job is not fine for me because i need to supply parameters to the called program and maybe i need call it more than once at the same time.
Is there a stored proc or a function I can call from Query Analyzer to execute another .EXE and return when it's finished?
I'd like something like SET @RET = sp_CallEXE('c:mypathmyprogram.exe myparameters')
(Except for the name of the function, there should be something that does this right? I mean, DTS does it already so it must be referring to a function or a SP.)
I want an answer to so that I can validate that everything went well (hence the @RET variable)
Student from norway needs help. After update on certain rows a trigger will trigg a program (using LDAP?) That fetches data and stores it in an Active Directory What should this trigger look like, it only starts another program.
Can anyone help me please. Healp please. Does anybody know how to make xp cmdshell runnable for users other than Admin. It should be possible to grant execute to others, but i can't figure out how.
This is what i found:
Be aware that when you grant execute permission for xp_cmdshell to users, the users will be able to execute any operating-system command at the Windows NT command shell that the account running SQL Server (typically local system) has privilege to execute.
To restrict xp_cmdshell access to users who have administrator permission on the Windows NT-based computer where SQL Server is running, use SQL Setup or SQL Enterprise Manager to set the server options, selecting the "xp_cmdshell - Impersonates Client" option. With this option selected, only users who have connected to SQL Server via a trusted connection and are members of the local Administrators group on that computer are allowed to use xp_cmdshell. The commands run by xp_cmdshell continue to execute in the server's security context.
I have to execute stored procedures containing xp_cmdshell and certain system storedprocedures in msdb and master with a user who is not SA. (i.e iam able to execute stored procedures when i log as sa, but any other user cannot run them)
Could anybody tell me how can I stop the executable program which I am using in Arguments field of Execute Process Task Editor window. My SSIS process based on three steps.
1. retrieve the file from FTP location 2. Process the file by using windows 32bit application 3. transfer the processed file back to FTP location
The problem occurs in step 2, it opens the win32 application for processing and it does process BUT after that it won't exit untill I close it manually, so it never reaches to step 3 if I don't close it.
Hi, I want to execute BCP in Query Analyser in SQL Server 2005 Express for that i surf on net and find that i should execute BCP under xp_cmdShell, That works good for addministritative account on SQL. But i want the working will be done by a non administrative account or non 'sa' user.How can i assign a non sa User permissions to execute xp_cmdShell? or just tell me any other alternative way to run BCP in Query Analyser or code behined. thanx
In SQL Server using xp_cmdshell we can excute any of the command or executable files which can be executed in command prompt. Here my problem is that .. I am trying to execute OSQL from the MSSQL(Query Analyser) using xp_cmdshell.. but its give error saying "'osql' is not recognized as an internal or external command, operable program or batch file." This error occours when it is not able to find the executable file... but same thing I am able to execute from the command prompt. So I feel this problem is some where related to the path setting of windows. If some one can solve this problem or sugesst the how to set the path for window it will be help full.. waiting for reply
I was trying to grant access for an application user for executing xp_cmdshell, but I got some error message saying that either doesn't the user exist, or I don't have the permissions to grant this. Does the user need to be a user in Master ? Or, don't I when logged in as "sa" have the sufficient permissions to grant execute on a SP in master?
I solved it by checking "Control server" under "Properties" > "Securables" for the login, but I don't actually want this login to have full control.
(And yes, I've read that allowing xp_cmdshell usage isn't recommended at all.)
A developer needs to execute an SSIS package from a stored procedure and I do not want to enable xp_cmdshell on SQL 2005.
One suggestion is to have the application invoke dtexec on the client PC, but this would cause the package to be executed on the client and also requires some SSIS components be installed on each client.
Another idea is to configure a Windows Service to execute dtexec, but I do not know the risks of this approach. Any thoughts?
I am trying to create a CLR based stored procedure in C#. When i tried printing simple "Hello" from it, it works fine. Now requirement is to run an exe file from it. For that i use process.start. But when i try to execute the procedure i get all the security execptions. Can someone please help. Following is the code snippet. -------------------------------------------------------------------------------------------------------------------------------------------------------------
public partial class StoredProcedures
{
[Microsoft.SqlServer.Server.SqlProcedure]
public static void RunProc(string arg)
{
SqlPipe pipe = SqlContext.Pipe;
pipe.Send("Hello");
Process.Start("E: est.exe");
}
}
CREATE ASSEMBLY [RunProcess]
FROM 'RunProcess.dll'
CREATE PROCEDURE dbo.sqlclr_RunProc
(
@arg nvarchar(1024)
)
AS EXTERNAL NAME [RunProcess].[StoredProcedures].[RunProc]
I've previous posted a message with error building the expression of the dtexec.exe string. But now, the problem is other, and I've decided to create other threat.
Here is what I'm doing: I've a SP that receives every parameter so I can build my dtexec.exe statement to be executed by a variable with something like this exec @rc = master.dbo.xp_cmdshell @CMD
Till now I have no problem executing it, not from a variable, but just with the statement itself, like this: exec master.dbo.xp_cmdshell 'C:PROGRA~2MICROS~290DTSBINNDTEXEC.EXE /SQ PACKAGE /SET "Package.Variables[PERIOD].Value";20070101'.
But now, I have this SP that builds the string into a variable and then I just want to execute it throught the variable like this: exec @rc = master.dbo.xp_cmdshell @CMD.
When I make a SELECT @CMD just before the exec @rc = master.dbo.xp_cmdshell @CMD, so it prints the builded string, copy it and pasted to exec master.dbo.xp_cmdshell 'copied string' it works fine. But the step of exec @rc = master.dbo.xp_cmdshell @CMD returns the error: The filename, directory name, or volume label syntax is incorrect.
Why is this, if I copy the generated string and execute it by the other way it works fine, but executing the generated string throught the variable it gives me that error?
Hi, I have been searching for an answer to allow me to execute xp_cmdshell from withing store prcedure by calling the store procedure from an aspx via click on a button. This is what I found from my reserch but was not able to know where to set the rights and what each of them means: "To run xp_cmdshell for a non-system administrator user, you must grant the following rights. MSSQLServer and SQLServerAgent Services Act as part of the Operating System. Increase Quotas. Replace a process level token. Log on as a batch job."
The above quote was from the following link: http://support.microsoft.com/default.aspx?scid=kb;en-us;264155
The bottom line is to be able to call a store procedure from an aspx page to execute the code which contain xp_cmdshell command, an example of such command is like: ------------------------------------------------------------ EXEC master..xp_cmdshell 'dir d:BT_importDatasales_option_price_report.csv'
Hi, I need to send a table data into flat and then ftp into different location. I was using xp_cmdshell via sql task but my network engineer is saying that this xp_cmdshell will break the security and recomond to use "Execute Process Task". If i'm using this task getting the below error. Could you advice me regrding network engineer thought and any solution for avoiding this error.
--------------------------- Execute Process Task: C:WINDOWSsystem32ftp.exe --------------------------- CreateProcessTask 'DTSTask_DTSCreateProcessTask_1': Process returned code 2, which does not match the specified SuccessReturnCode of 0. --------------------------- Thanks,
We connect to the remote database servers through the network from loca by using Query Analyzer. Previously we were able to execute the xp_cmdshell command from local Query Analyzer to fetch the remote databases data. But now we are unable to execute the xp_cmdshell command on remote databases from local Query Analyzer We do not know what happened but i think due to network updates this command is not able to execute...
For ex: Previously i was able to execute master..xp_cmdshell 'net start' from local Query Analyzer.But now not able to execute
Now my question is, is there any other way(Directly or indirectly) to execute the xp_cmdshell command on remote databases from local?
Note : we are able to execute this command on remote Query Analyzer but not from local QA
Hi,I am having some trouble copying data over my workgroup network from my Windows 2003 Server Machine (machineA with SQL SERVER 2005) to one of my network Machine's drive(MachineB).Here is the T-SQL code that I am trying to execute:EXEC xp_cmdshell 'copy D:Datafile.txt \MachineBDocuments'Whenever I tried to execute the above piece of code, I get the error message "Access is denied", but if I try to copy the file from the Command Prompt (cmd.exe) with the copy command, the file copies fine over the network.I have already searched over the internet and I found out that loads of people have the same issue, and they were suggested something like this:"Check in Services and make sure that the MSSQLServer service is run as a domain user and that domain user has rights to these network resources."Well it sounds plausible, but I don't know what are the exact steps to do this. How do I know which user is running the MSSQL Server service? Are they referring to the user which I use to connect to my SQL Server Database engine throuhg the SQL Server Management Studio?Also they are suggesting 'domain user', and as I said before I do not have domain network just regular simple workgroup network.Here are some details of the user that I use to login. I generally login into my Windows 2003 Server machine with user called 'User1' and I use the same 'User1' to connect to SQL Server through the Management Studio Screen.Should I create a user called 'User1' on my MachineB(Destination Machine)?I would really appreciate, if someone can give me detailed steps explaning how to solve this problem.Thank you very much once again.

I need the file created by my BCP QUERYOUT command I'm executing from XP_CmdShell in Transact-SQL to have a specific OWNER. I've tried using the sp_xp_cmdshell_proxy_account to setup the correct owner. The owner is always SERVERNAMEAdministrators.
what the program will do if we caught that exception .. i need some suggestions ... i got this exception(String or binary data would be truncated. The statement has been terminated.).. will it affect the functionality of the program...
Basically a dts package has been setup that pulls in data from another companies server, this data requires to be on-demand i.e individual users can pull in updates of the data when they require it.
I am using xp_cmdshell and dtsrun to pull in the data. This obviouly works fine for me as i am a member of sysadmin.
Books online quotes " SQL Server Agent proxy accounts allow SQL Server users who do not belong to the sysadmin fixed server role to execute xp_cmdshell"
So i went to the SQL Server Agent Properties 'Job System' tab and unchecked 'Non-sysadmin job step proxy account' and entered a proxy account.
The proxy account has been setup as a Windows user with local administrator privilages and even a member of the sysadmin server role - just in case.
Now when i log onto the db with my test account - a non-sysadmin - and attempt to run the stored proc to import the data i recieved the message 'EXECUTE permission denied on object 'xp_cmdshell', database 'master', owner 'dbo' '
hmm... so basically i have either misunderstood BoL or there is something not quite right in my setup.
I have search the net for a few days now and yet i can find no solution.
I had got the below error when I execute a DELETE SQL query in SSIS Execute SQL Task :
Error: 0xC002F210 at DelAFKO, Execute SQL Task: Executing the query "DELETE FROM [CQMS_SAP].[dbo].[AFKO]" failed with the following error: "The transaction log for database 'CQMS_SAP' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
But my disk has large as more than 6 GB space, and I query the log_reuse_wait_desc column in sys.databases which return value as "NOTHING".
So this confused me, any one has any experience on this?
I'm looking for a way to refer to a package variable within any Transact-SQL code included in either an Execute SQL or Execute T-SQL task. If this can be done, I need to know the technique to use - whether it's something similar to a parameter placeholder question mark or something else.
FYI - I've been able to successfully execute Transact-SQL statements within the Execute SQL task, so I don't think the Execute T-SQL task is even necessary for this purpose.
I have a master package, which executes child packages that are located on a SQL Server. The Child packages execute other child packages which are also located on the SQL server.
Everything works fine when I execute in process. But when I set the parameter in the mater package ExecutePackageTask to ExecuteOutOfProcess = True, I get the following error
Error: 0xC00470FE at DFT Load Data, DTS.Pipeline: SSIS Error Code DTS_E_PRODUCTLEVELTOLOW. The product level is insufficient for component "Row Count" (5349).
Error: 0xC00470FE at DFT Load Data, DTS.Pipeline: SSIS Error Code DTS_E_PRODUCTLEVELTOLOW. The product level is insufficient for component "SCR Custom Split" (6399).
Error: 0xC00470FE at DFT Load Data, DTS.Pipeline: SSIS Error Code DTS_E_PRODUCTLEVELTOLOW. The product level is insufficient for component "SCR Data Source" (5100).
Error: 0xC00470FE at DFT Load Data, DTS.Pipeline: SSIS Error Code DTS_E_PRODUCTLEVELTOLOW. The product level is insufficient for component "DST_SCR Load Data" (6149).
The child packages all run fine when executed directly, and the master package runs fine if Execute Out of Process is False.
i have a program which should give the out like this XAPIALTMKT20010829105525.TXT
but its giving the output = 'X' which is just the first initial...how can i get this...
if i don't write the @filename=.... only then its giving the output..but i want to store it in the varable..how can i do that ================================ declare @v datetime , @filename varchar
It is very interesting to me that most people in this group can't do simpleSQL. Are you viewing MySQL as a simple file system?As long as you do that,you willnot understand SQL in any dialect. So from now on:When you have a question about SQL. post the table structures. Uh, "WithCreate".Post some sample data in the form of INSERTS.Regards,Rich--The journey is the reward.
I am trying to send an email from a cmd prompt from SQL Server 2005 server using mailsend program. I am getting the message "Could not send mail". I am really stumped, don't know how to fix it. Any suggesstions?
I have installed SQL Server 2005 and created a job. I made the job failed to test the mailsend program. The notification step that uses the mailsend succeeded but I did not get an email. I am using mailsend program on SQL Server 2000 and it works fine. I am really stomped and don't know what to do to fix it?
