Problem With Context Switching Feature In SQL 2005
Jan 26, 2007
Hi,
One of our client application launches a execuatable on server by calling master..xp_cmdshell. We are migrating to SQL 2005 and I would like to use the Context Switching feature
We have sql login client? which is used by clinet application and has very least privelge and have only required access to requried database and tables.
xp_cmdshell is disabled by default on our server and I would like to enable xp_cmdshell, launch the executable on the server and disable xp_cmdshell.I have created another SQL Login Bob? and is member of sysadmin. The below SP is created by logging in as Bob?. My objective is to grant execute access on this SP and grant impersonate access to sql login client? . So that client application connecting to SQL server can launch the executable by calling the SP
create proc Bob.[Bob_enable_xp_cmdshell]
with execute as 'Bob'
as
EXEC sp_configure N'show advanced options', N'1' RECONFIGURE WITH OVERRIDE
EXEC sp_configure N'xp_cmdshell', N'1'
RECONFIGURE WITH OVERRIDE
EXEC sp_configure N'show advanced options', N'0' RECONFIGURE WITH OVERRIDE
-- launch the application using xp_cmdshell and disable the xp_command shell
When I try to execute (exec [Bob].[jtr_enable_xp_cmdshell]
) the above SP by logging in as Bob, Im getting the below error
Msg 15247, Level 16, State 1, Procedure sp_configure, Line 94
User does not have permission to perform this action.
Msg 5812, Level 14, State 1, Procedure jtr_enable_xp_cmdshell, Line 4
You do not have permission to run the RECONFIGURE statement.
Msg 15123, Level 16, State 1, Procedure sp_configure, Line 51
The configuration option 'xp_cmdshell' does not exist, or it may be an advanced option.
Msg 5812, Level 14, State 1, Procedure jtr_enable_xp_cmdshell, Line 6
You do not have permission to run the RECONFIGURE statement.
Msg 15247, Level 16, State 1, Procedure sp_configure, Line 94
User does not have permission to perform this action.
Msg 5812, Level 14, State 1, Procedure jtr_enable_xp_cmdshell, Line 7
You do not have permission to run the RECONFIGURE statement.
Please note the SQL Login Bob? is a member of sysadmin fixed role. Thank in advance for you help.
I need to allow only a specific group of users to use a linked server. Rather than granting each user access in the linked server I create and give access to a local SQL login "link_user" and then grant the group impersonate to "link_user". The folllowing statements then work fine:
EXECUTE AS LOGIN = 'link_user'
SELECT * FROM OPENQUERY(linked_server, 'SELECT * FROM ...)
But when I use the exact same statements in a stored procedure I get the folllowing error:
Msg 7416, Level 16, State 1, Procedure linktest2, Line 5
Access to the remote server is denied because no login-mapping exists.
I need to be able to work with the result set which is why I use OPENQUERY rather than EXECUTE... AS... AT which works fine also in stored procedures!?
Is there another workaround then to create all users in the linked server security?
I have installed sql server standard edition 2005.I want to enable service broker feature or services after intalling the sql server.Please let me known any tool or utiltiy to enable the feature
Alter datatabase set enable_broker is not working.
Hello everybody, I'm not completly aware of the SQL server 2005 possibilities so I'd need an hints from somebody with a wide knowledge to understand the direction to take!
This is what I have to do.
I insert into a table XML message. the messages are pushed automatically by an application I have no ""control" on and I get several messages "at the same time".
Everytime the message is inserted into the database I need to trasform the XML data into the correspondent relational value and I know already that in some cases it could take a while (1 second can be considered a while..) My worry is that in the moment I process one message I loose the other one inserted after ,,,
There is some tool that helps me to handte the process as I would..

I downloaeded "Microsoft SQL Server 2005 Datamining Viewer Controls" feature pack, and tried to run the dataminingviewerclient.exe.
When i view my local time series data mining model, It works well for single series model, but when i load a Microsoft time series model containing multiple data series, an unhandled exception occurs.
I post the error message below:
See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.

Can someone help to figure out what went wrong? thx.
I've tried to installed sql server 2005 developer edition on windows vista home premium but failed many times, almost giving up. I've installed and turned on all the features of IIS 7.0 but it still failed and I tried to test IIS 7 by running the local host and received this error " HTTP Error 500.0 - Internal Server Error." I even ran the windows update SP1 for Vista and MDAC 2.8 SP1
I really appreciate any comments and help.

Hello, I have an XP box with SQL 2k working without any problems. I am trying to install SQL 2005 CTP April on the same machine. Installation goes fine, but when I try to connect, I am getting an error "Can not Create SSPI Context". Why am getting this error ? DOes the machine needs to be on a domain to get connected? If yes, is there a work around? Can I use mixed mode? WhereHow do I specify password for sa?
Hi there,I have installed MS SQL Server 2005 on my machine with windows authentication. But now I want to switch the authentication mode to SQL Authentication. I am unable to switch, I canât find the proper way to do so here in 2005.Could any one help me in doing this?Thank you,-Ahsan
I know sysprocesses has the information, but I can't seem to find how this is done using the dmv's. sessions doesn have a db context, and requests is only active while activity is occurring.
Hi-I have a program that I am developing on a laptop, then deploying it on a server.I have the prgram running passing a username and PW in the connection object, but like the idea of using windows authentication MUCH better.I just joined the domain, so I am domain/me for example.If I log into the server, and look at securities, logins and added domain/me to the logins.I then try and set up a sql connection via both visual studio, and sql server magt studio, and get the dreaded "Cannot generate SSPI context" error. Anyone else have this problem? SHOULD V.S. be using domain/me to connect? TIA dan
At the moment my asp.net app is working ok and I can connect to the database using windows authentication, however i'm trying to use sql authentication on my local computer.i'm using sql server studio at the moment to manage the database. And tried numerious combinations of things to try and get it working and allow me to connect to the database using SQL authentication but still no luck :(can anyone give me some rough step by step instructions to setting up the sql username and password for forms authentication and activating it for a certain database?thanks
If I have a connection open which is in database master, can I switch to another database within that connection without having to close the connection and recreating it?
Guys! I'm using SQL Mail to send out Emails to Customers re: outstanding Invoices. I also use SQL Mail on the same box to send out emails to our Sales Reps with summaries of outstanding invoices. Now, I've set up multiple outlook profiles on the server. I tried using
DOES NOT WORK!!! the profile does'nt switch at all. SQL Mail sends out all the emails using the profile that it started with. How can I use xp_startmail and xp_stopmail to switch between different user profiles.
If I dump a replicated Db and restore it onto another DB, how do I switch off replication from the restored DB. I believe there were some scripts developed for this in 6.5.
We have an active database that sits on SQL Server 2000 that currently has per seat license...but now want to switch to per processor. If I go to ControlSQL Server 2000 License Set up...it doe not give me the option to choose per processor.
Do I need to un-install/re-install SQL Server 2000 and choose the per processor choice and then re-attach our database ?
I sometimes have problems when running index rebuilds due to the tran log growing too big. MS suggest switching the db from full recovery mode to bulk-logged mode fur the duration of the rebuild. Question is, when you switch a db from full recovery to bulk logged, does that invalidate the tran log backups up to that point? When the db is switched back into full-recovery mode, are the following tran log backups still in sequence?
I would like to know how I can switch from one database to another within the same script. I have a script that reads the header information from a SQL BAK file and loads the information into a Test database. Once the information is in the temp table (Test database) I run the following script to get the database name.
This part works fine.
INSERT INTO @HeaderInfo EXEC('RESTORE HEADERONLY FROM DISK = N''I:TESTdatabase.bak'' WITH NOUNLOAD') DECLARE @databasename varchar(128); SET @databasename = (SELECT DatabaseName FROM @HeaderInfo);
The problem is when I try to run the following script nothing happens. The new database is never selected and the script is still on the test database.
EXEC ('USE '+ @databasename)
The goal is switch to the new database (USE NewDatabase) so that the other part of my script (DBCC CHECKDB) can run. This script checks the integrity of the database and saves the results to a temp table.
My C# application has a DataGridView which is bound to a DataSet. I used Visual Studio to add/configure the data source. Everything works fine on my computer. When I try to run the application on another computer I can't connect to the database, because it uses a wrong connection string.
How can I make a specific connection/connection string permanent for a specific application?
I've got a situation where I need to execute portions of a script against every database on a given instance. I don't know the name of all the databases beforehand so I need to scroll through them all and call the "use" command appropriately.
I need the correct syntax, the following won't work:
DECLARE DBS CURSOR FOR SELECT dbname FROM #helpdb ORDER BY dbname
OPEN DBS
FETCH NEXT FROM DBS INTO @dbname
WHILE @@FETCH_STATUS = 0 BEGIN
USE @dbname
The last line - the "USE" statement - is invalid. The following for example works:
USE master
But when supplied a declared variable a syntax error results for the use command because it expects an identifier.
So .. what is the correct syntax to pass a declared parameter to "USE", or is there another way to meet this requirement?
i want to upload reports in ssrs , when i trying to configure reporting service configuration manager, getting error" there was an error while switching panels. The most likely cause is an error retrieving wmi properties. the exception details are access is denied . You must have an administrator on the report server computer to use this tool".
It is simple question, just slipped out of my mind at this time...... how do we change Security Context for 2005 version from network to local system. thanks,
I need to pull data from an Excel Workbook (DTS Excel Source) where the data is stored in worksheets that are each named one of the twelve months of the year. The package is fired by a job that runs once a month. Currently, I have to go into the select statement of the Excel source before the process runs and change the name of the Worksheet that the data is pulled from.
How can I set up the sql statement for the Excel source so that I can pull from the Worksheet that contains the name of the current month?
Hi all--I used the following type of script to migrate tables, views and stored procedures from 'dbo' to 'hqmsuser': alter authorization on dbo.PK_T_PQ_MASTER to HQMSUSER alter schema HQMSUSER transfer dbo.PK_T_PQ_MASTER go
This was per recommendations from the BOL to use instead of the 'sp_changeobjectowner' procedure. I returned the following error:
Msg 15346, Level 16, State 1, Line 3 Cannot change owner for an object that is owned by a parent object. Change the owner of the parent object instead. Msg 15347, Level 16, State 1, Line 4 Cannot transfer an object that is owned by a parent object.
How do I find and change the parent object on this from 'dbo' to a non-dbo schema ownership?
Iâm looking for clearity on partition switching. The idea is to use many BULK INSERT statements into table dbo.X_n in parallel and when BULK INSERT for table dbo.X_n is completed, switch dbo.X_n into dbo.bigdaddy. I think this is the fastest way to upload a couple hundred GB of data.
In learning about partition switching (in part) from The Data Loading Performance Guide under Partition SWITCH, I hear the instructions to say copy the main table exactly to become a target. But in that same step (#1), I read that we need to change the default file group of the target (dbo.X_n) from the default file group. Then it says I need to match indexes and lists the filegroup as something we need to match with the main table.
As an overview of the partition switching strategy, I think the whole point of BULK INSERT with partitioning is to have seperate files (in same group) to enable concurrent uploading where each table has its own file. Once the upload is completed to a table (dbo.X_n) then we do the partition switch into the main table (dbo.bigdaddy). The data we just uploaded doesnât actually move, just the metadata for it.
When I read the instructions linked above, I hear âDonât have the same filegroup on your target as the main table. You must have the same filegroup on your target as the main table.â
