in WM 9 the default session type for new Integration Server services has changed from stateful to stateless.
All existing or migrated services retain their session type.
Is there a way to change the type for all existing services ina a package (filesystem script, programaticaly…)
This propery is stored in node.ndf file of each service.
you can change it using file system script. make sure you take back up of packages before running the script.
There is also a service in wmRoot pkg to change the service properties
Since wmRoot pakage is not advised to be used by us, use it at your own risk!!
