user wants a long article for the keyword "opatchauto72030 execute in nonrolling mode exclusive". I need to provide a comprehensive guide. I'll search for information about opatchauto, OPatch Auto, and the specific command. I'll also search for "opatchauto72030" and "nonrolling mode exclusive". I'll search in both English and Chinese. search results show several relevant pages. I need to open them to gather detailed information. have gathered information from various sources. I need to write a long article. The article should explain the error, the difference between rolling and non-rolling modes, how to fix it by using the -nonrolling flag, and provide additional tips. I'll structure the article with an introduction, a section on understanding the error, a detailed explanation of patch modes, a step-by-step fix, an advanced section on exclusive execution, and a FAQ. I'll cite the sources. you execute opatchauto on an Oracle Grid Infrastructure (GI) cluster, you might be abruptly stopped by an error that reads OPATCHAUTO-72030: Execution mode invalid and OPATCHAUTO-72030: Cannot execute in rolling mode, as CRS home is shared . This error forces you to re-evaluate the patching strategy, and it often leads to the required action: opatchauto72030 execute in nonrolling mode exclusive . This article aims to be your comprehensive guide to understanding and resolving this situation, providing a detailed breakdown of the error, its causes, and the exact commands to fix it.
1. Understanding the OPATCHAUTO-72030 Error The error message OPATCHAUTO-72030 is a clear directive from the OPatchAuto utility. It indicates a fundamental incompatibility between the mode of operation you attempted (rolling) and the configuration of your Oracle environment (shared CRS home). Typical Error Scenario When you run a command like the one below without the required parameters, you will be met with this error: /u01/app/19.0.0/grid/OPatch/opatchauto apply /soft/35319490 -oh /u01/app/19.0.0/grid
The resulting output will look like this: Shared home /u01/app/19.0.0/grid can only be patched in nonrolling mode. OPATCHAUTO-72030: Execution mode invalid. OPATCHAUTO-72030: Cannot execute in rolling mode, as CRS home is shared. OPATCHAUTO-72030: Execute in non-rolling mode. OPatchAuto failed.
Key Takeaway: The system is telling you that because your CRS (Cluster Ready Services) home is in a shared location (accessible by all nodes), it cannot be patched in a rolling fashion. The only viable path forward is to execute the operation in non-rolling mode . This is the foundational concept for this article. opatchauto72030 execute in nonrolling mode exclusive
2. Deep Dive: Rolling vs. Non-Rolling Mode To understand why this error occurs, you need to understand the difference between the two patching modes supported by OPatchAuto. Rolling Mode (The Default)
Operation: When using rolling mode, the processes on a particular node are shut down, the patch is applied to that node, and then the node is brought back online. This process repeats sequentially for each node in the cluster. Requirement: For a rolling mode session to start, at least one remote node must be up and running . The local node from which you execute the command must also be operational. Benefit: The main advantage is zero downtime (or minimal downtime) as the application remains accessible via the other nodes while patching occurs. This is the most efficient mode for applying interim patches. Limitation: Not all patches can be applied using rolling mode. The patch's metadata will specify if it is "rollable".
Non-Rolling Mode
Operation: This mode operates in three phases. Starting with 12c, it requires the GI stack to be up on the local node, but the process involves patching one node at a time, then nodes two through n-1 in parallel, and finally the last node. Requirement: For a non-rolling session to start, ALL remote nodes must be shut down . While local node processes are running, the remote nodes must be down. Purpose: Non-rolling mode is used when the patch cannot be applied in a rolling fashion, for example, when applying a patch to a shared CRS home.
Why the Error Occurs: By default, opatchauto applies patches in rolling mode unless you instruct it otherwise. When you run opatchauto without the -nonrolling flag, it defaults to rolling. However, a shared CRS home is incompatible with this process. The utility checks the environment, detects the shared home configuration, and correctly throws OPATCHAUTO-72030 to prevent an invalid operation.
3. How to Fix: Executing in Non-Rolling Mode The solution to the OPATCHAUTO-72030 error is to explicitly instruct opatchauto to use the non-rolling mode by including the -nonrolling flag in your command. Here is the correct syntax to resolve the issue: /u01/app/19.0.0/grid/OPatch/opatchauto apply /soft/<patch_location> -oh /u01/app/19.0.0/grid -nonrolling user wants a long article for the keyword
