HPSM DC to DR Auto Switch Over Process

Hello, Anyone have gone through the process of SM DC to DR Auto Switch Over Process in the past? Could you please let me know your valuable inputs regarding the same? I can't really find any official documentation for this activity.
  • Yes, I did implemented/tested it already; nothing special required for SM; you need to make sure to have it on all layers, most important Database which will depend on your database system and should be set by your database team, (Oracle TAF is not supported and lead to problems), for webtier also standard procedure regardless you use tomcat only or any other more robust combination with F5 or another external load balancer. About the Application, the same. Nothing special, you relly on your operation system capabilities, scripts or external tool to perform the Switch Over, like the standard Windows Fail Over.
