| Feature | Rolling Mode (Default) | Non‑Rolling Mode | |---------|------------------------|------------------| | | One node at a time. | All nodes simultaneously. | | Cluster availability | Cluster remains available (though services move). | Cluster is fully down during patching. | | Downtime required | Minimal per node; overall longer patching time. | Single, longer downtime window. | | Failure risk | Lower; if one node fails, others still run. | Higher; any failure affects whole cluster. | | Use case | Most RAC patches, online patching. | Non‑RAC (standalone), or when rolling mode is not allowed by patch notes. |
| Area | Requirement | |------|--------------| | | Patch 72030 unzipped on all nodes (or a shared location accessible to all). | | Inventory Access | oracle and grid users must have write access to Central Inventory ( /etc/oraInventory ). | | Cluster Services | All cluster services must be functional ( crsctl check cluster ). | | Backup | Full backup of Oracle home ( tar -czf or opatch util backup ). | | Root Access | Root password or sudo configured for running root scripts. | | Patch Conflicts | Run opatch prereq CheckConflictAgainstOHWithDetail against current home. | | Shared Storage | Non-rolling mode still requires shared storage for OCR/Voting disks to be online. | opatchauto72030 execute in nonrolling mode

In the complex world of Oracle Database administration, patching is both a necessity and a challenge. Keeping Oracle Grid Infrastructure (GI) and Real Application Clusters (RAC) environments secure and stable requires a deep understanding of the tools Oracle provides. Among these tools, opatchauto (now often referenced within the opatch ecosystem for standalone and cluster patching) is critical for applying patches to Oracle home directories. However, one specific command syntax has been gaining attention among seasoned DBAs: . | Cluster is fully down during patching
