The error typically occurs during Oracle Grid Infrastructure (GI) patching when the system is unable to proceed in "rolling" mode (where nodes are patched one by one without total cluster downtime). This message indicates that a non-rolling mode execution is required, often due to a shared home configuration or specific patch requirements. Understanding Error OPATCHAUTO-72030
opatchauto is an intelligent wrapper around OPatch that automates patching for Oracle homes. It determines the current cluster state, stops/restarts services as needed, and applies patches consistently across nodes. opatchauto72030 execute in nonrolling mode exclusive
For non-rolling mode, manually stop applications, listeners, and databases if you want full control: Faster overall execution time (parallel patching of nodes
Some patches contain changes that are incompatible with running mixed versions across a cluster simultaneously. Execution Workflow (Non-Rolling Mode) For non-rolling mode
