These two posts explain the mechanism really well to extend VRA (VMware vRealize Automation) with VRO (VMware vRealize Orchestrator) to execute external script that is located in the External Guest Operating System folders (either Windows or Linux).
It is really useful if you want to execute one of these use cases :
– Silent Installation of Database/Apps platform (ex: SQL Server, Oracle DB, MySQL, PostgreSQL Apache, etc after the VM is deployed)
– Configure parameters in Apps, DB, Middleware, agents (ex: NetBackup agent, Oracle DB, Tomcat, Weblogic, etc) after the VM is deployed)
– Execute other external scripts that is located in Guest OS
Please note that you also can use it with VRO only, if you don’t want to automate the process from VRA.
