Five years ago, I wrote a blog post titled The SYNCHRONIZED SSIS Execution Parameter. Recently, I received a comment with a question:
One way to execute SSIS packages stored in the SSIS Catalog from SQL Agent is to use the CmdExec job step type. As with all command-level access, please research security implications.
Use a command similar to that shown below to override the SYNCHRONIZED SSIS Catalog execution parameter value:
dtexec /ISServer "\SSISDB\Folder\Project\Package.dtsx" /Server "server\instance" /Par $ServerOption::SYNCHRONIZED(Boolean);"true"
Please keep the questions coming!
Hope this helps,
