Does anyone know of a way to check for an instance of a DTS package?
E.g. I have a package called 'Package1' that is currently running.
Someone else attempts to run the package and before they can i want to check if an instance of 'Package1' already exists, if it does then the package will not run.
possible or pipedream?
cheers

I'm a bit confused about how ssis handles concurrent package runs
let's say I'm running this package and I 've got 3 variables set in it
VARA
VARB
VARC
and by default they are all set to 0
if I run
dtexec /File "C:ControlRoom.dtsx" /SET PackageVersion_Builder.Variables[VARA].Value;1
dtexec /File "C:ControlRoom.dtsx" /SET PackageVersion_Builder.Variables[VARB].Value;1
dtexec /File "C:ControlRoom.dtsx" /SET PackageVersion_Builder.Variables[VARC].Value;1
I'm expecting to run 3 isloated version of the package with in
first version
VARA=1
VARB=0
VARC=0
second version
VARA=0
VARB=1
VARC=0
third version
VARA=0
VARB=0
VARC=1
but it doesn't seem like doing that the maxconcurrent variable is set to 40 to be on the safe side.
when I run I get
first version
VARA=1
VARB=0
VARC=0
second version
VARA=1
VARB=1
VARC=0
third version
VARA=0
VARB=1
VARC=1
any ideas?
Thanks
I've run into a problem with SSIS packages wherein tasks that write or copy files, or create or delete directories, quit execution without any hint of an error nor a failure message, when called from an ASP.NET 2.0 application running on any other machine than the one where the package was created from. By all indications it appeared to be an identity/permissions problem.
Our application involves a separate web server and database server. Both have SQL Server 2005 installed, but the application server originally only had Integration services. The packages are file system-deployed on the application server, and are called using Microsoft.SqlServer.Dts.Runtime methods. For all packages that involve file system tasks, the above problem occurs.
When the above packages are run using the command prompt (either DTEXEC or DTEXECUI) the packages execute just fine. This is expected since we are using an administrative account. However when a ShellExecute of the same command is called from ASP.NET, the same problem occurs.
I've tried giving administrative permissions to the ASPNET worker process user to no avail.
I have likewise attempted to use the SQL Server Agent job approach but that approach might not be acceptable for our clients since it means installing SQL Server 2005 Database services on the application server.
I have read the relevant threads in this forum, namely http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1044739&SiteID=1 and http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=927084&SiteID=1 but failed to find any solution appropriate for our set up.
Anybody got any idea on how to go about this?
We manage some SSIS servers, which has only SSIS and SSIS tools installed on them and not the sql server DB.
SSIS packages and configuration files are deployed on a NAS. We run the SSIS packages through DTEXEC by logging in to the server.
We want to allow developers to run their packages on their own on the server, but at the same time we dont want to give them physical access on the server i.e we do not want to add them into RDP users list on server properties. We want them to allow running their packages remotely on the server.
One way We could think of is by using powershell remoting and we are working on that. But is there any other way or any tool already present for the same.
Hi all
Our data management system currently runs DTS packages using DTSPKG.dll.
I am currently looking at the possibliity of replacing the DTS packages and SQL 2000 with DTSX packages using SSIS in SQL 2005.
Do I need a new dll? or will the current dtspkg.dll handle the new DTSX packages?
Many thanks in advance!
I've two instances(Default, Named[dynamicsFINANCE]) running on SQL server 2014. However, when I try to connect to named instance say (dynamicsFINANCE) using SQL authentication from local SSMS, I get below error message:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)
I assigned a static port number to the named instance [dynamicsFINANCE] 1450. I also setup the firewall rule to allow access to Port 1450.
Hi fellows,
I have to migrate all objects alogwith all constraints,SP,Triggers, indexes etc from Development instance to Production instance of a DB, all those things are created through wizard ie. Sql server 2000 Enterprise Manager. if i use DTS it only mirates data along with tables and views but constraints,SP,Triggers, indexes etc not yet copied.
can any body help me how can I solve this problem by copying all objects alogwith all constraints,SP,Triggers etc from Development instance to Production instance.
This is Sql server 2000 Cluster environment.
thanks in advance for any help

I have a 3 node cluster on which I have installed SSAS as it's own insntance. I have created this as a named instance and can connect to it by serverinstance if I'm on the server itself. However from my desktop I get the error saying instance was not found on server name.
I have defined an alternate port and setup firewall rules and can connect via server:port but not serverinstance. Prior to making this change SSAS was running on default port of 2383 and I could connect just by servername.
I have read many articles for previous versions saying that clustered SSAS will always use 2383 and that you must connect just using servername. However and this is were it gets strange. I have a 2 node UAT cluster with SSAS setup exactly the same way I've described above and I can connect from my desktop as serverinstance.
Should I be able to connect as serverinstances for a named clustered instance in 2012 ?
Hi, I have a task in hand to migrate (upgrade) from SQL2K named instance to SQL2K5 default instance. There are many intranet applications touching current SQL2K. I would like to perform this upgrade such that I don't have to touch any application code - meaning I don't have to change the connectionstring to point to new Default instance. How can I achieve this?
So, in otherwords, here is what I want to achieve:
Current Server: SQL2K: SERVER_AINSTANCE_A (named instance)
Upgraded Server: SQL2K5: SERVERB (default instance)
If I have both default, I could achive this by setting up DNS alias after migration done so that any call for SERVER_A would point to SERVER_B. But in my case, I don't have SERVER_A, I have named instance. Is there any solution?

Hi,
I want to move one database from the source SQL Server 2000 instance to a new SQL 2000 instance in another machine. I have five user databases in this source SQL instance. How should be my approach to move this single database out of this ? My understanding is restoring this database in the new instance, copying all logins to the new instance and then copying the jobs, DTS packages, alerts, operators only specific to this database will do it. Please let me know if this is exactly what I should do ..
Thanks in advance..

I am trying to set up a Named Instance of SQL 2000 on the same machine that has a default instance of SQL 7.0. The setup always completes and I am able to register the Named Instance of the SQL Server with which it was installed on. However, when I try to connect the users to the database, with both windows and SQL authentication, I receive a SQL server not found error. I have tried an alias setup as well as physically specifying the port number in settup up an ODBC connection.
Has anyone ran into similar problems?
Also, has anyone been able to successfully complete the process as mentioned above?
I have a server with sql server 2005 installed as the default instance -- I have a piece of software that needs SQL2000 to be the default instance. Is there a way other than install new sql2005 named instance and move databases to rename my SQL2005 instance from <machinename> to <machinename>sql05 for example?

Hi all,
i have installed SQL client instance on my Desktop "Machine-A", and i used to connect to SQLServer2000 running on another "Machine-B" by using valid username and password.
i created a DTS package and i used to run it. im very confused how the communication happens between the two machines and which process run where and which initiates which and which machine allocates waht resources. im really interested to know all these things. if any one know plz help me out.

I have SQL Server 2000 Standard Edition (sp3a) running on a windows 2003 (sp4) Server.
It is a Production Server with 3 NAMED Instances and NO Default Instance.
Does anyone know if I can rerun the SQL Server Install and add a DEFAULT Instance to this box without disrupting the other Named Instances???
I work for a mid size company with the usual collection of enterprise applications. We are trying to consolidate our SQL environment consisting of around 100 databases none of which are over 100GB with the average database size around 5GB. Recently a large server was purchased as the "Big Daddy" SQL box. Obviously not all the databases will be moved to this one box but within reason a number can.
My question: What is the best way to configure the box?
1 OS & 1 Default Instance - How do we isolate loops memory leaks etc...
1 OS & Multiple instances, ie:Dedicated instance for each application. - How do you allocate CPU & memory, allow for optimum performance without putting others at risk from a rouge process?
Virtualized OS for each application with a default instance - Too much overhead impacts performance?
Future plans include offsite replication, perhaps mirroring with failover.
I'd appreciate anyone else's thoughts ideas? How have you tackled this problem in your environment?
Thanks

I installed SQL Server 2005 recently on a cluster. I didn't go for the default instance and instead I named the instance option. Now I would like to migrate everything from the named instance to the default instance, which I haven't yet installed.
Is this an easy process? What about the logins and the maintenance plans and jobs? Is there anything else I need to be aware of?
Hi
I've never had to do this, but when I downloaded the Web Workflow Approvals Starter Kit, it requested that I install the database into a User Instance of .SQLEXPRESS.
Now the problem is, I've installed it onto a default instance, so I was wondering whether you can create a named instance on top of a default instance... and if so, how would you do that?
Cheers

Got windows Vista Business edition, installed Visual Web Developer Express, SQL Server 2005 Express SP2, SQL Server Management Studio SP1 in that order. I was developing in VWD express without problems using WinXP but now on Vista Business, the local connection to SQL server appears to be a problem.
I know there's nothing wrong with my web.config or anything like that as it was working perfectly prior to running under Vista. If i specify the database on the live website, it works fine. If I specify the test database in app_data folder, I get the following exception:-

I am taking a guess it's somerthing to do with access issues, but can't find anything out on searching the forums etc..
I am setup as an administrator, running VWD as an administrator and for the record, SQL Server Management Studio express works fine.
Another small issue, when I run the application from VWD, I always have to minimise the application and restore it as the graphics get corrupt.
Please help!! I cannot debug when running of the live website.
The box I am trying to connect to is running two instances of SQL Server.
There is a SQL Server 2005 instance which is the default. There is a SQL Server 2000 instance which is named 'SQLSERVER'.
I can connect to the SQL Server 2000 instance no problem:<add key="ConnectionString" value="server=MYPCSQLSERVER;database=mydatabase;user id=****;password=****" />
However, I am having trouble connecting to the Default SQL Server 2005 instance. I have tried:
<add key="ConnectionString" value="server=MYPC;database=mydatabase;user id=****;password=****" />
but it doesn't work. I have tried explicitly setting SQL Server 2005 to use port 1434 (as SQL Server 2000 is running on port 1433), and then used:
<add key="ConnectionString" value="server=MYPC,1434;database=mydatabase;user id=****;password=****" />
but this doesn't work either.
Am I mssing something here? Any help much appreciated
Thanks...

Hello everyone,
I am new in .NET development and currently trying to learn VWB through Microsoft online tutorials.
Here is the problem that prevents me from getting further:
in VWB, when you right click App_Data and chose "Add New Item" and then select SQL database, the following error message is displayed:
"Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed."
If I cancel out of it, it does generate mdf file under App_Data folder in Solution Explorer, but when I try to open it, it says:
"The item does not exist in the Web directory. t may have been moved, renamed or deleted." and that is where the whole sharade deadends.
I can connect via mycomputersqlexpress under Data Connections in Database Explorer (it then adds "master.dbo" to the path) and then create custom tables, but that is not the same, isn't it? I mean, this will not integrate my database tables through default configuration that I am trying to follow?
All this happens on local machine.
Thanks to everybody who can help!

I was able to do do this before until Saturady when I had to re-install sql server, and express etc due to some system problem on my xp Pro PC. What have I misconfigured?
I do see the service SQL Serer(SQLEXPRESS) started under Network Service and SQL Serfver(MSSQLSERVER) started under local system.
My power user ID does have modify access to the sql 90 database folders. and to the mdf.
No wonder Microsoft is giving it away for free. It€™s not worth anything. I am very disappointed in this version of SQL server. I decided to start learning VB so I downloaded and installed VB 2005 express edition and SQL 2005 express. I tried to build a personal website using the starter kit. I kept getting the following error message, for which I have seen numerous postings on this forum.
€śFailed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.€?
I went out and bought the Standard version of VS 2005 thinking there may be a feature that the free express version is lacking. I uninstalled the express version, cleaned the registry, deleted all the folders it created and installed the Standard edition. Then I tried to create a personal web using the starter kit and it does the same thing again.
I can not create a database file, connect to a database file. I can not create or attach a database on the SQL 2005 express from VS 2005. The SQL server Express seems to be working OK since I can attach to it using Microsoft SQL Server Management Studio Express. There is something about the way VS tries to connect to the database server that is not working. VB does recognize the local computer as a SQL server but can not connect to it.
SQL server is set to accept Shared memory, TCP/IP and named pipes for local clients.
What is causing this?

Hello everybody,I was configuring a SqlDataSource control using SQL Authentication mode.I first added a database file (testdb.mdf) through Solution Explorer-Add New Items. Then through Database Explorer I created a table named "info"Then while configuring the SqlDataSource control I used the SQL Authentication mode and attached the "testdb.mdf" database file.Test Connection showed success. But when I hit the Ok button of the wizard it displayed the following error message:Failed to generate a user instance of SQL Server. Only an integrated connection can generate a user instance.While configuring the SqlDataSource control I clicked "New Connection". Under Data Source section I tried both Microsoft SQL Server and Microsoft SQL Server Database File. And in both the cases I attached a databese file(testdb.mdf). Plz enlighten me on this.Thanks and Regards,Sankar.

Can someone show me some C# code for detecting if a SQL row exists or not? This seems like a very typical action and I cannot for the life of me find a tutorial online that explains this step. In my code I'm either going to INSERT or UPDATE a record. I tried sending a SELECT command through a ExecuteNonQuery, but only got -1 as a response. Apparently ExecuteNonQuery does not work with SELECT. I then saw that T-SQL has an EXISTS keyword, but I cannot see anyway to use that from within C#.So...can anyone share the typical code they use to identify if a row exists or not within a database. I guess I was execting there to be some method available to do this sort of thing.

I'm currently using US English version of Windows NT4 and SQL7. But interestingly, all the data is in Japanes characters. It's actually for a Japanese website, and the front-end application is written in ASP. I remember reading somewhere that it is impossible to do certain type of sorting (by some particular order for the Japanese language) as it is limited by the choice of the language of the NT OS.
The type of sorting that I'm looking at is the grouping of 5-characters. One example is in http://www.forest.impress.co.jp/aiueo.html
Would this be possible with my current setup? Or would it help if I migrate over to Windows 2000? (I'd rather not move to Japanese NT4)
Your feedback and advice would be very much appreciated!
