Opatchauto72030 Execute In Nonrolling Mode -
Assuming you have met all prerequisites, here is the exact procedure to apply patch 72030 across a 2‑node or multi‑node cluster in non‑rolling mode.
Using opatchauto in non-rolling mode is straightforward but results in Total Downtime. Always ensure the patch README specifically supports non-rolling application (most do, but some specific security patches or major upgrades may have specific requirements).
Pro Tip: Always run
opatchauto analyze -nonrollingfirst to verify that non-rolling mode is required and supported for patch 72030.
This guide assumes a basic familiarity with Oracle patching processes and might need adjustments based on your specific situation. Always consult Oracle documentation or contact Oracle Support for detailed, version-specific instructions.
The error code OPATCHAUTO-72030 typically signals a logical deadlock in an Oracle administrator's day: it occurs when you attempt to run a patch in rolling mode, but the patch itself—or a specific conflict—demands a non-rolling execution.
Here is a story of a late-night maintenance window where this error took center stage. The Midnight Maintenance
The clock struck 11:00 PM on a Friday. Elias, a Senior Database Administrator, sat in the glow of three monitors. His mission was simple: apply the latest Quarterly Patch Update (QPU) to a critical four-node Real Application Clusters (RAC) environment.
To minimize downtime, Elias chose the rolling mode. In his mind, he’d update Node 1 while the others stayed live, then move through the cluster like a ghost. He typed the command:./opatchauto apply /u01/app/oracle/patches/353535 -rolling The Wall of Red
The progress bar crawled to 12%. Then, the terminal spat out a wall of red text:Execution failed: OPATCHAUTO-72030: The patching cannot proceed in rolling mode.
Elias frowned. The error was blunt. It explained that certain components in this specific patch—perhaps shared Grid Infrastructure binaries or a mandatory upgrade to the clusterware stack—required the entire cluster to be down simultaneously. By trying to keep the lights on, Elias was technically trying to perform "surgery on a marathon runner while they were still mid-race."
The error was a safeguard, preventing Elias from corrupting the cluster's consistency. He had two choices: argue with the logs or follow the machine's logic.
Downtime Approval: He sent a quick alert to the stakeholders. "Rolling mode unavailable due to patch constraints. Initiating full cluster downtime."
The Shift: Once the services were drained and the instances silenced, he adjusted his strategy.
The Command: He cleared the failed session and re-ran the tool without the rolling flag:./opatchauto apply /u01/app/oracle/patches/353535 -nonrolling Resolution
The nonrolling mode took over. Instead of the delicate dance of one node at a time, opatchauto laid waste to the entire stack at once, updating the binaries across all nodes in parallel. By 1:30 AM, the terminal finally blinked a green success message.
Elias learned that while "rolling" is the dream for availability, OPATCHAUTO-72030 is the reality check that ensures the foundation of the database remains solid—even if it means a few hours of silence in the data center.
The error message "OPATCHAUTO-72030: Execute in non-rolling mode" typically occurs during Oracle Grid Infrastructure (GI) or RAC database patching when the opatchauto utility detects an environment that does not support the default rolling mode. By default, opatchauto attempts to patch nodes sequentially (one at a time) to maintain high availability. However, certain configurations—most notably shared Oracle Homes—require a full cluster shutdown and a non-rolling execution. Why OPATCHAUTO-72030 Occurs
The primary reason for this specific error code is a Shared Oracle Home configuration. In a shared home, multiple nodes use the same physical installation binaries. Since a rolling patch updates binaries while they are still in use by other nodes, it would cause immediate system instability or failure. To protect the environment, opatchauto throws error 72030 to force a full maintenance window. Other triggers for non-rolling mode include:
Non-Rollable Patches: Some patches contain metadata explicitly stating they cannot be applied in a rolling fashion due to significant binary or architectural changes.
Pre-check Failures: If opatchauto detects that remote nodes are down or the cluster stack is inconsistent, it may require a non-rolling approach to resynchronize the nodes. How to Execute in Non-Rolling Mode
To resolve the 72030 error, you must explicitly tell the utility to use the non-rolling method by adding the -nonrolling flag to your command. Standard Syntax:
# As the root user from the GI_HOME/OPatch directory: ./opatchauto apply Use code with caution. Steps for Non-Rolling Patching:
Preparation: Download the latest OPatch utility and your target patch from My Oracle Support. Back up your Oracle Homes before proceeding.
Stop Remote Nodes: In a non-rolling session, all remote nodes must be shut down. Only the local node where you run the command should have the GI stack up.
Execute Apply: Run the opatchauto apply command with the -nonrolling flag.
Verification: Once completed, use ./opatch lsinventory to confirm the patch is successfully applied across the homes. Key Differences: Rolling vs. Non-Rolling Non-Rolling upgrade in RAC using opatchauto - Oracle Forums
A key feature of opatchauto when encountering the OPATCHAUTO-72030 error is its ability to enforce Non-rolling Mode for shared Oracle homes, which ensures cluster integrity by patching all nodes while the services are down. Key Feature: Shared Home Enforcement opatchauto72030 execute in nonrolling mode
In Oracle RAC environments, if the Grid Infrastructure (GI) home is shared across nodes, it cannot be patched using the default "rolling" method (one node at a time while others stay active). The opatchauto utility features a built-in safety check that triggers error OPATCHAUTO-72030 to prevent invalid execution.
To resolve this, you must explicitly use the -nonrolling flag. Benefits of Non-rolling Mode
Speed & Efficiency: Unlike rolling updates that patch sequentially, non-rolling mode allows for parallel patching of nodes two through , significantly reducing the overall maintenance window.
Compatibility: This mode is mandatory for "non-rollable" patches or configurations (like shared homes) where the patch metadata does not support active services on remote nodes.
Automation: Even in non-rolling mode, opatchauto automates the complex sequence of stopping services, applying binary patches, and restarting the stack across the cluster. Execution Requirements When running in non-rolling mode:
Little things worth knowing: what does opatchauto actually do?
When you encounter the error OPATCHAUTO-72030: Execute in non-rolling mode, it typically means the patch you are applying is "non-rollable" or that your environment (such as a shared Grid Home) does not support rolling updates. Direct Solution
To resolve this, you must explicitly use the -nonrolling flag in your command:
# Example command as root user # Use code with caution. Copied to clipboard Critical Pre-patching Requirements
Because non-rolling mode involves stopping services across the cluster, you must ensure the following conditions are met:
Remote Nodes Down: All remote nodes must be shut down before starting a non-rolling session.
Local Node Up: The local node (where you execute the command) must be up to initiate the session.
Stop Entire Stack: For non-rollable patches, you should manually bring down the Oracle Clusterware stack on all nodes to prevent conflicts.
Run as Root: The opatchauto utility must be executed with root privileges. Common Troubleshooting Scenarios
Shared Grid Home: If your Grid Infrastructure (GI) home is on shared storage, it can only be patched in non-rolling mode.
Failed Session Resume: If a session fails during an analyze phase, you may need to find the session JSON in $GRID_HOME/OPatch/auto/dbsessioninfo/ and manually change the nonrolling flag from false to true before running opatchauto resume.
Directory Permissions: Ensure you are not running the command from /root or /, as this can cause permission errors; run it from a directory where the home owner has write access.

In the world of Oracle Database administration, the error OPATCHAUTO-72030: Execute in non-rolling mode
is often a cryptic guardian standing between a DBA and a successful patch application. The Conflict: The "Shared Home" Limitation
Our story begins with a DBA attempting a routine patch update on a high-stakes environment—specifically, a Grid Infrastructure (GI) system. By default, opatchauto
tries to be a hero, attempting to apply patches in "rolling mode" to maintain zero downtime by patching one node at a time. However, the hero hits a wall when it detects a shared Oracle Home
. In a shared home configuration (like those found on some Cluster File Systems), you cannot patch one node while the others are still running off the same binaries. This creates an invalid execution mode, triggering the dreaded OPATCHAUTO-72030 The Turning Point: Making the Hard Choice
To bypass this guardian, the DBA must switch tactics from "rolling" (no downtime) to "non-rolling" (system-wide maintenance window). Stop the World
: In non-rolling mode, the environment requires a total shutdown. The DBA must manually bring down all databases and stacks across every node in the cluster. Explicit Instruction Assuming you have met all prerequisites, here is
: The tool is no longer allowed to guess. The DBA must explicitly add the -nonrolling flag to the command line: # opatchauto apply
stops trying to "roll" through the nodes. Instead, it systematically applies the patch to the GI and RDBMS homes while the services are down. Final Verification
: After the bits are laid down, the DBA brings the stacks back up. For the final touch, they may need to run
on the last node to ensure all SQL changes are synchronized within the database. OPATCHAUTO-72030

Executing Opatchauto in Non-Rolling Mode: A Step-by-Step Guide
Opatchauto is a powerful tool used for applying patches to Oracle databases. In certain scenarios, you may need to execute opatchauto in non-rolling mode. This guide provides a comprehensive overview of the process, including prerequisites, execution steps, and best practices.
What is Opatchauto?
Opatchauto is a utility used for applying patches to Oracle databases. It automates the patching process, making it easier to manage and maintain your database.
What is Non-Rolling Mode?
Non-rolling mode, also known as " downtime" mode, involves shutting down the database and applying patches without maintaining availability. This mode is typically used when the patch cannot be applied in rolling mode or when the database needs to be patched urgently.
Prerequisites
Before executing opatchauto in non-rolling mode:
Executing Opatchauto in Non-Rolling Mode
opatchauto <patch_dir> -nonrolling
Replace <patch_dir> with the actual directory path.
Example:
opatchauto /u01/patches/12345678 -nonrolling
Post-Patching Steps
Best Practices
Troubleshooting
If issues arise during patch application:
By following these steps and best practices, you can successfully execute opatchauto in non-rolling mode and ensure a smooth patching process.
The error OPATCHAUTO-72030 typically occurs during Oracle Grid Infrastructure (GI) or RAC patching when the utility determines it cannot proceed in the default rolling mode. This usually happens because the Oracle Home is shared across nodes or the specific patch metadata mandates a non-rolling application. Understanding OPATCHAUTO-72030
This error is an orchestration failure message that states: "Cannot execute in rolling mode, as CRS home is shared" or "Execute in non-rolling mode". In a shared-home environment, binaries cannot be updated while other nodes are still using them, necessitating a complete cluster shutdown for the duration of the patch. Patching Procedure in Non-Rolling Mode
To resolve this and successfully apply your patch, follow these structured steps: Preparation and Downtime:
Stop the Stack: In non-rolling mode, the Grid Infrastructure (GI) stack and all associated databases must be stopped on all nodes. Pro Tip: Always run opatchauto analyze -nonrolling first
Permissions: Ensure you are executing the command as the root user.
Execution Syntax:Use the -nonrolling flag explicitly to override the default rolling behavior.
# Example command syntax /u01/app/19.0.0/grid/OPatch/opatchauto apply Use code with caution. Copied to clipboard
Community experts on FreeLists often suggest verifying your OPatch version before execution, as outdated versions are a common cause of "strange errors" during this process. Post-Patching Steps:
Once the binary application completes on all nodes, restart the GI stack.
Manual Datapatch: If the patch includes SQL changes, you must manually run datapatch on the database to ensure the bug fixes are fully applied. Troubleshooting Resources
If you encounter persistent issues, refer to the following documentation and tools:

Applying a patch in non-rolling mode with opatchauto requires all nodes in a Grid Infrastructure (GI) or RAC environment to be shut down simultaneously. This mode is typically used when a patch contains changes that are not compatible with different versions running at the same time, such as major metadata or structural updates. Core Execution Logic
In a non-rolling session, the orchestration follows a specific sequence:
Downtime Requirement: All nodes (including the local and all remote nodes) must be stopped before starting the session. Patching Sequence: opatchauto begins by patching a single node.
It then patches the remaining nodes (nodes 2 through n-1) in parallel.
Finally, it patches the last node (n) to complete the session. Prerequisites & Preparation
Environment: Ensure the ORACLE_HOME and GRID_HOME environment variables are correctly set. Permissions: The command must be executed as the root user.
SSH Configuration: User equivalence (passwordless SSH) for the root user across all nodes must be configured for remote execution.
Backup: Perform a full backup of the Oracle Home and GI Home before proceeding. Command Syntax
To force a non-rolling update, you must explicitly include the -nonrolling flag:
