Better Way To Deploy SSIS Pkg

I am looking for a way to deploy SSIS pkg from dev to test/prod.

Which Is Best Way To Deploy SSIS Packages?
Sep 7, 2007I have 9 Dimensions and 16 Fact Packages in my SSIS Project. All these 25 packages uses one source (SQLServer A - staging) and a seperate destination (SQlServer B - Warehouse) . I have completed my development. Now i want to move these packages to production environment. I have a Parent package to control all these facts and Dimensions.
1. Should I always change the Protection level of the Package to "DontSaveSensitive" before moving to some other machine where it has to run under a different user?
2. Which is the best way to follow for configuring the connection strings in my development?
Having a variable for each connection string @ parent project level and pass it to child packages
or
Configure the connection strings directly in a XML config file for one package and in all my other packages i have to say the package to Reuse the existing config file as the source and dest is same for all these packages?
And am hearing one more buzz word "Proxies for running SSIS packages". Any information on this also will help me.
Please help!!!
Thanks in Advance.

Error While Trying To Deploy SSIS Package
Sep 1, 2006Hi,
I am trying to deploy a DTSX package to 32-bit SQL Server 2005 in a 64-bit machine from my installer.
I am getting the following error in the SaveToSQLServer method:
The SaveToSQLServer method has encountered OLE DB Error code 0x80004005 (Communication Link Failure). The SQL statement that was issued has failed.
However I am not facing this problem when I try to deploy the DTSX package to a 32-bit SQL Server 2005 in a 32-bit machine.
Can anyone tell me why this happens and how this could be solved?
Thanks,

Deploy SSIS Package To Server
Aug 6, 2007Ok, I created SSIS packages on my local box. All of my packages are using config files for the db connections and other configurations that'll be changed per environment. My question is how do I deploy the .dstx file and the associated config file to the servers?
Right now I'm running the packages in BIDS as I create them. I now want to run them on an actual server
Deploy SSIS Without Installing SQL Server 2005
Apr 13, 2007SSIS packages can also be run on systems where SQL Server is not installed.
How do we package the DTUTil.exe and DTEXEC.EXE. with the manifest file
How do we execute the packages using the file system utility.
Any suggestions/help is appreciated.

Noob To SSIS Package Configure And Deploy
Mar 19, 2007Hi there
I am fairly new to SSIS, I got my package running fine in my development environment with the connection managers (connecting to 3 databases on the same server, with username and password, not Integrated security) and all.
The problem comes in when i want to deploy my package or execute it outside of the development environment.
When I execute the .dtsx file in my project it brings up the Execute Package Utility and I just click Execute, thinking it should work, but not, any ideas??
So I read some of the forums and got looking into the configuration file, suppose that it does not carry the connection manager settings thru, but dam that still doesn't work for me?
The whole idea is that I will be executing the package from my C# code, so does my package have to be just on the server in a folder or does it have to be installed in the db? which is best??
Hope anyone can help me!!
Thanks

Permissions To Deploy SSIS Package To SQL Server
Jan 31, 2008
What are the minimum permissions required to deploy an SSIS package to SQL Server? Here is what I have tried:
1. No additional permissions (i.e user created with no special permissions):
Deployment Error: No execute permissions on sp_put_package???
2. Dbowner role on msdb dataabase
Deployment Error: The SaveToSQLServer method has encountered OLE DB error code 0x80040E14 (Access to Integration Services package 'xxx' is denied.). The SQL statement that was issued has failed.
3. Sqladmin role on login: No errors
Most DBAs are reluctant to give sqladmin role to developers. Is there any way around this restriction?

Cannot Deploy SSIS Package On 64bit SQL Server
May 17, 2006
I have a SSIS package, which get data from oracle 9i, and dump into sql server 2005 64bit itanium, its running fine. When I am deploying the package on SQL Server 2005 its showing me the error with connection. on 64bit Oracle Net manager showing its able to connect oracle successfully. I think actually the problem is with encryption, as the package is developed on 32bit machine, therefore all connection strings are encrypted for that machine. Is there some has faced same issue? please help!

Apr 16, 2008
Hi there,
Something a little wride mysterious is happening with my package when I deploy it to run at the SSIS server instance. Everytime that I try to deploy it (from my local development environment) to SSIS server, my package is not keeping its database user and password.
As the database user and password are the same one we dont need to use the XML setting to keep these data there.
So, does anyone know what could be happening with my package and/or my deployment?

Deploy SSIS Package To Production Which Has A Connection To Oracle Databse
Aug 14, 2006Hi There,
In SSIS package development environment, I was able to connect to an oracle database and pull data into my sql server database. I installed the client tools for oracle and I put an entry into the tnsnames.ora and I was able to connect.
But in production environment, if I deploy the package on sql server, I was wondering if I had to do the same job of downloading the oracle client tools onto my production machine --which creates a tnsnames.ora file to it default location and then edit it with tthe tns entry-- or is there a better way to do this--avoiding the download?
Can somebody plzz help me ?

Can Not Deploy Reports
Feb 27, 2008
I have created a report project file on my local machine.Now I'm trying to deploy those reports to a development server. I have installed sql server and tools in my local machine but never configured reporting services. When I try to deploy those reports, it asks username and password for reporting services login.
But usually as far as I know, i should be able to deploy my reports without entering password etc. Even if I enter username and password, still they dont work.
Is that becase I install SQL server in my local machine?
Does anyone know why?
Thanks
