Single XML configuration file for all the SSIS packages(including parent and child packages)

Question

Hi
I have some 16 ssis packages. source Db and destination Db for these packages are common. I am calling these child packages in a master package.
I want to use only one XML config file for this master.
How do i use same for all child packages?
and can i do it with parent package variable?

Answer 1

I created a master package with a variable master, and in value i have entered the configuration file path.
Hi vjp dinu,
You should create variables in the parent package to pass values to variables in each child package rather than pass the file path of the XML Configurations file of the parent package.
As Visakh mentioned, you can achieve your goal by creating corresponding variables in the parent package for each child package, and enable Package Configurations for the parent package so that you can control the values through the XML Configurations file
for the variables of the parent package.
Supposing there is a variable FilePath in child package 1, a variable ServerName in child package 2, then, we need to create two variables pFilePath, pServerName in the parent package. After configuring the Parent package variable in each child package (e.g.
mapping pFilePath to FilePath, pServerName to ServerName), you can enable XML Configurations for the parent package, and expose the value property for both pFilePath and pServerName variables. In this way, you can modify the XML Configurations file of the
parent package and the specified values will passed to the child packages.
