Opatchauto72030 Execute In Nonrolling Mode High Quality High Quality | Original - Series |

crsctl stat res -t crsctl check cluster -all

Unlike rolling mode (zero downtime), non-rolling mode requires taking a complete outage for all nodes in the cluster simultaneously.

. This is often triggered by specific patch constraints or the OPATCHAUTO-72030

Execute the shutdown command on the node you are patching. # CRS_HOME/bin/crsctl stop crs -f Use code with caution. crsctl stat res -t crsctl check cluster -all

Patching is a critical maintenance task. By adhering to these best practices, you ensure high quality, minimal risk, and a smooth operation for your Oracle RAC environment.

Ensure your core patching tools meet Oracle's prerequisites for the specific patch ID. Check your current OPatch version: $ORACLE_HOME/OPatch/opatch version Use code with caution. # CRS_HOME/bin/crsctl stop crs -f Use code with caution

: All nodes sharing the Oracle home must be down during the patching process to ensure binary consistency. How to Execute in Non-Rolling Mode

When managing Oracle Grid Infrastructure and Database environments, ensuring a secure and up-to-date system is critical. Oracle provides opatchauto to automate the patching process across multiple Oracle homes, such as Grid Infrastructure (GI) and Database homes. However, scenarios arise—particularly with complex configurations, specific patch requirements, or severe node constraints—where applying patches in a rolling fashion isn't possible.

After the command completes with exit code 0 , perform these checks:

Confirm that no Oracle processes are running. # ps -ef | grep ohasd # ps -ef | grep d.bin Use code with caution. If any processes remain, kill them manually using kill -9 . Phase 3: Sanitize the Inventory and Locks
