Introduction
Oracle Grid Infrastructure 19.29 Patch Installation is a critical maintenance task for database administrators ensuring their Oracle 19c environments remain secure, stable, and up to date. The 19.29 (October 2025) release includes cumulative fixes and enhancements for the Clusterware and ASM components within Oracle Grid Infrastructure.
This guide provides a detailed, step-by-step walkthrough for applying the 19.29 patch to a standalone Oracle Restart (single-node) environment using OPatchAuto, following Oracle’s best practices and validation methods.
Environment Details
| Component | Version / Path |
|---|---|
| Oracle Grid Home | /u01/app/19c/grid |
| OPatch Version | 12.2.0.1.47 |
| Patch Bundle | 38298204 (includes sub-patches 38291812, 38322923, 38311528, 38380425, 36758186) |
| User | grid (installation), root (execution) |
| Server | prod |
Step 1 – Check the OPatch Version
Before applying any patch, confirm that the OPatch utility version is compatible with the target Oracle Home.
[root@prod OPatch]# ./opatch version
OPatch Version: 12.2.0.1.47
OPatch succeeded.
✅ Result: The latest OPatch version (12.2.0.1.47) supports the 19.29 release.
Step 2 – Run Conflict Checks
Run the conflict check for all sub-patches contained in the patch bundle to ensure there are no overlapping updates.
Example commands:
/u01/app/19c/grid/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /home/oracle/install/38298204/38291812
/u01/app/19c/grid/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /home/oracle/install/38298204/38322923
/u01/app/19c/grid/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /home/oracle/install/38298204/38311528
/u01/app/19c/grid/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /home/oracle/install/38298204/38380425
/u01/app/19c/grid/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /home/oracle/install/38298204/36758186
Repeat for each sub-patch:
- 38291812
- 38322923
- 38311528
- 38380425
- 36758186
✅ Result:
Each returned:

The system meets all space requirements for the patching process.
Step 4 – Apply the 19.29 Patch Using OPatchAuto
Now, apply the patch bundle automatically using opatchauto, which handles pre-patch, binary apply, and post-patch operations.
/u01/app/19c/grid/OPatch/opatchauto apply /home/oracle/install/38298204 -oh /u01/app/19c/grid
📋 Process Overview:
- Pre-Patch Operations: CRS services are gracefully stopped.
- Binary Application: Patch binaries are applied to the Grid Home.
- Root Script Execution:
rootadd_rdbms.shruns to integrate patch components. - Post-Patch Operations: CRS services are restarted and validated.
✅ Sample Output Snippet:
/u01/app/19c/grid/OPatch/opatchauto apply /home/oracle/install/38298204 -oh /u01/app/19c/grid
