In SQL Server Management Studio, under SQL Server Agent, Jobs folder, I double-click a job. This opens the Job Properties window. Then I go to Steps, and double-click the first step of the job. This opens the Job Step Properties window as below:
In the Package textbox is a path to a .dtsx file. The path is similar to \SSISDB\...\Step1Package.dtsx
Where is this .dtsx file located on the SQL server? And how can I view the file? Can I use Visual Studio 2017 to view the .dtsx file?
See the package source. It says SSIS Catalog
. You'll find your package at below location:
Integration Services Catalogs -> SSISDB -> <your package path>
The reason being, you've deployed the SSIS solution as Project Deployment Mode
Additional info : Microsoft document on SSIS deployment mode
