| Pitfall | High‑Quality Solution | |--------|------------------------| | Patch fails due to missing prerequisites | Read the README thoroughly. Use opatch prereq CheckApplicable. | | SSH key expired between nodes | Run ssh node2 date as grid user before starting. | | Insufficient memory in OPatch | Increase JAVA_OPTIONS or use ‑J‑Xmx1024m flag. | | Partial inventory corruption | Back up $ORACLE_HOME/inventory before execution. | | Patch applies but cluster won’t start | Re‑run opatchauto to fix configurations, then review logs. |

Because non‑rolling mode implies full cluster downtime, the cost of failure is high. Every minute the cluster is down impacts business operations. Therefore, executing opatchauto72030 with high quality means: opatchauto72030 execute in nonrolling mode high quality

In non‑rolling mode, you must shut down the entire cluster cleanly:

crsctl stop cluster -all

Wait for all nodes to show CRS is down via: crsctl stat res -t | Pitfall | High‑Quality

crsctl check crs

# For Oracle Grid Infrastructure home (RAC or standalone)
$ORACLE_HOME/OPatch/opatchauto apply <patch_location> -nonrolling
Q1: Can I interrupt opatchauto in non‑rolling mode?

No. Interrupting can leave the cluster in a mixed‑state. Always let it complete or use opatchauto resume if supported.
Q2: Does non‑rolling mode affect ASM disk groups?

Yes, ASM instances on all nodes are stopped and restarted together. Ensure no databases rely on ASM during the window. Wait for all nodes to show CRS is
Q3: How do I handle failures during execution?

Check the opatchauto log. Usually, you can fix the issue (e.g., free space, missing RPM) and re‑run the same command. opatchauto is idempotent.
Q4: Is there a way to simulate non‑rolling mode?

Yes, use ‑analyze flag:

opatchauto apply . -nonrolling -analyze
