Hi Anyone knows after deploying changed custom.property file using AC

Only a restart to the application server will be needed to reflect the changes

It depends on the property you're updating. There are properties that only impact the app server requiring just its restart but there are others such as the ones in the server.conf domain that will impact the engines therefore need a restart of both.

Got it, thanks!

will this require restart of both App server & Engines
