In this second installment of a two-part series, we’ll be going over Phase Two, the build out of standard pre- and post-patching automation, and Phase Three, the build out of application-specific pre- and post-patching automation. Click here for Phase One. Status Report With basic patching and reboots automated, a patching session for application environments without any special pre-patching and post-patching activities was reduced from 20 minutes per server, down to 6 minutes per server.
