Opatchauto72030 Execute In Nonrolling Mode High Quality | 95% Authentic |

Rolling mode changes will be rejected if patch levels are inconsistent across nodes. The error message will indicate: "Rejecting rolling patch mode change because the patch level is not consistent across all nodes in the cluster".

— Before starting any patching session, ensure all nodes in the cluster are at the same patch level. Inconsistent patch levels will trigger error codes CRS-1162 and CRS-1171, blocking the operation

If opatchauto failed mid-way during a previous run, the Grid Infrastructure home might remain in a locked or read-only state. You must unlock the home before running the patch utility again. Run the following command as the root user: # $GRID_HOME/crs/install/rootcrs.sh -unlock Use code with caution. Step 5: Execute Opatchauto with Precise Flags opatchauto72030 execute in nonrolling mode high quality

Central or local inventory files are out of sync across the cluster nodes.

Verify the location of your central inventory by viewing /etc/oraInst.loc . Rolling mode changes will be rejected if patch

export OPATCH_DEBUG=true opatchauto apply <patch-location> -nonrolling

# As root user /u01/app/19.0.0/grid/OPatch/opatchauto apply /images/patches/36123456 -nonrolling Use code with caution. (Replace 36123456 with your specific Patch ID) Step 3: Complete Patching on Remaining Nodes Inconsistent patch levels will trigger error codes CRS-1162

The opatchauto apply -analyze command simulates a complete patching session by running all prerequisite checks without modifying the system. This low‑cost check can save hours of troubleshooting later.

Before any patching:

When scripting OPatchAuto invocations, always check for the -nonrolling flag if your environment uses shared homes. The article "How to Execute Oracle 12c RAC Rolling Patch Upgrade" emphasizes that opatchauto must include the -nonrolling parameter, as its default behavior is to patch across nodes in parallel. This violates the fundamental RAC requirement of "single-node serial isolation for changes." The -nonrolling flag is not disabling rolling patching entirely—it is the switch that tells the tool to only operate on the current node and not schedule other nodes for parallel patching.
