By default, opatchauto attempts a to maintain zero-downtime. In a shared-home configuration (where multiple cluster nodes read from the same centralized Oracle Grid Infrastructure binary location), a rolling update is physically impossible. Modifying active shared binaries while another node is executing them causes corruption and node failure.
In the high-stakes world of Oracle Database administration, patching is a necessary yet often dreaded task. The complexity increases exponentially when dealing with Oracle Grid Infrastructure (GI) and Real Application Clusters (RAC). Oracle provides the opatchauto utility to streamline this process, but within its syntax lies a specific, powerful, and potentially disruptive command: .
: In rolling mode, at least one remote node must be active; however, for shared homes, the utility cannot isolate the local node's binaries for patching without affecting the entire cluster. How to Execute in Non-Rolling Mode opatchauto72030 execute in nonrolling mode exclusive
To resolve this, you must stop all services across all nodes and use the -nonrolling flag with OPatchAuto .
A: No. For Oracle 19c Release Updates (RUs), Oracle recommends a manual process using opatch apply on each node and then running datapatch , as opatchauto is largely deprecated for this use case. By default, opatchauto attempts a to maintain zero-downtime
The failure message indicates that the orchestration engine cannot proceed in the default "rolling" mode (patching one node at a time while others stay up).
When used correctly, non-rolling exclusive mode simplifies patching and reduces total maintenance time. When misused, it can lead to extended downtime. Always respect the patch README and Oracle’s rolling/non-rolling guidelines. In the high-stakes world of Oracle Database administration,
The "nonrolling mode exclusive" execution is the standard requirement for these environments to ensure the shared binaries are modified while the entire stack is down.
Oracle's OPatchAuto orchestration engine evaluates your architecture before modifying the environment. In standard multi-node cluster topologies with local, unshared Grid Infrastructure homes, patches are deployed sequentially—node by node—to prevent application downtime.
Once the analysis completes successfully, you must apply the patch to , ensuring the -nonrolling flag is explicitly appended. Log in as the root user on Node 1 . Run the explicit non-rolling apply command:
