I tried and search many blogs to find solution about
Having SSISDB database on database server and Intergation Services catalogs on application server.
My company policy does not allow to have database engine running on application server, but need to execute SSIS package on application server using new method of Integration Services Catalogs.
I know I can create SSIS model packages and run from application server, If anyone done keeping SSISDB database on separate server and catalogs on different server then please advise
