We've been working to get some SSIS packages deployed to our SSISDB catalog in the sql server. After fixing umpteen issues with permission in proxy accounts the latest issue is this;
After deploying the project to the SSISDB (SQL Server 2012) then either updating the existing SQL Agent job to use the deployed SSIS package OR deleting it and creating a fresh agent job, the sql agent is detecting a connection manager to the dev SQL Server that I deleted from the package. This is causing a failure when the job runs with some sort of permissions issue however the connection manager doesn't exist in the package. I even checked the XML code for the connection managers and there is nothing in there for the one I deleted.
I can't understand how the SQL agent is detecting a connection manager in the configuration tab of the job step when that connection manager isn't visible in the package dev files anywhere.
I've deleted and re-deployed the project after saving it in Visual Studio again and again.
Is there some deep, hidden setting somewhere that contains more connection data? It feels like the problem lies more with SSMS than SSIS but at this point I'm lost!
