Cleaning Up Inactive Patches in Oracle RAC

🧼 Cleaning Up Inactive Patches in Oracle RAC

In Oracle RAC environments, patches accumulate over time, many of which become inactive due to rollback, superseding, or failed attempts. These inactive patches can clutter the patch inventory, slow down operations, and introduce inconsistencies across nodes. This post explains how to clean them up safely using opatch util deleteinactivepatches, and why it's essential to run this under both Grid Infrastructure and Oracle RDBMS users. 


$ORACLE_HOME/OPatch/opatch util deleteinactivepatches -silent

🔍 What Does This Command Do?

This command removes all inactive patches from the Oracle inventory. These include:

  • Rolled-back patches
  • Superseded interim or PSU patches
  • Obsolete metadata left from earlier patch attempts
It frees up space, reduces conflict risk, and improves future patching performance. The -silent flag allows it to run without user input.

⚙️ Importance in RAC Setup

Oracle RAC requires consistent patch levels across all cluster nodes. An unclean patch inventory can:

  • Cause mismatched metadata errors
  • Slow down opatchauto validations
  • Increase cluster-wide patching time
To avoid these, patch cleanup must be performed under both:
  • grid user — for Grid Infrastructure Home
  • oracle user — for RDBMS Oracle Home

🛠 Mandatory Cleanup Steps (Grid + Oracle Users)

Follow these steps in both Grid and Oracle environments: 


sudo su -
su - grid

# 🔍 Check inactive patches
$ORACLE_HOME/OPatch/opatch util listorderedinactivepatches

# 📁 Check OPatch config
cat $ORACLE_HOME/OPatch/config/opatch.properties
# ➤ Ensure this line exists:
# RETAIN_INACTIVE_PATCHES=1
# This setting keeps the latest patch and one one-off for rollback safety.

# 🧹 Delete inactive patches
$ORACLE_HOME/OPatch/opatch util deleteinactivepatches -silent

exit

# Repeat the same steps for Oracle RDBMS home
su - oracle

# 🔍 Check inactive patches
$ORACLE_HOME/OPatch/opatch util listorderedinactivepatches

# 📁 Check OPatch config
cat $ORACLE_HOME/OPatch/config/opatch.properties
# ➤ Ensure this line exists:
# RETAIN_INACTIVE_PATCHES=1

# 🧹 Delete inactive patches
$ORACLE_HOME/OPatch/opatch util deleteinactivepatches -silent

🔁 Note: Both users must perform the cleanup on their respective Oracle Homes to maintain RAC consistency.

🔐 Best Practices

  • ✅ Set RETAIN_INACTIVE_PATCHES=1 in opatch.properties
  • ✅ Always validate patch success before cleanup
  • ✅ Backup Oracle Home and Central Inventory as a precaution
  • ✅ Automate cleanup via post-patch scripts or Ansible

📌 Conclusion

Using opatch util deleteinactivepatches as both grid and oracle users ensures a clean and consistent environment for future patching. It's a must-have step in your Oracle RAC patch lifecycle, and doing it right helps avoid inventory bloat, improves performance, and simplifies maintenance. Add it to your post-patch checklist today! ✅

⚡ Automating Oracle 19c Database Patching on Windows Server with PowerShell

Applying Oracle patches on Windows often feels repetitive and error-prone — stopping services, updating OPatch, applying patches, running datapatch , and restarting services. To save time ⏱ and reduce mistakes ⚠, I created a PowerShell automation script that performs the patching process end-to-end 🚀. 🔹 Why Automate Oracle Patching? ⏱ Save time by automating repetitive steps ⚙ Avoid manual errors during patching 📜 Maintain logs for auditing and troubleshooting 🛡 Ensure consistent, reliable patching 🔹 Full PowerShell Script # --- CONFIGURATION --- $oracleHome = "c:\users\administrator\downloads\v982656-01" # Change if this is not your actual Oracle Home! $patchDir = "C:\Users\Administrator\Downloads\p37962957_190000_MSWIN-x86-64\37962957" #update the Patchfile directory $opatchDir = "$oracleHome\OPatch" $opatchZip = "C:\Users\Administrator\Downloads\p6880880_190000_MSWIN-x86-64.zip" #Based on your setup update Opatch di...

Installing pgBackRest on Linux (RHEL 9 / Rocky / AlmaLinux)

 When you work with PostgreSQL in real environments, one thing becomes very clear very quickly: Backups are not optional. It doesn’t matter how stable your database is — failures happen. Disks crash Files get corrupted Someone runs the wrong delete query A patch goes wrong A standby needs rebuilding. So having a proper backup strategy is not just good practice, it’s survival. That’s exactly why tools like pgBackRest are so widely used in PostgreSQL production systems. In this post, I’ll walk through a simple installation of pgBackRest on a Linux server (RHEL 9 / Rocky Linux / AlmaLinux). Why pgBackRest? PostgreSQL already provides tools like: pg_dump pg_basebackup And yes, they work. But once your database grows, or you start managing HA setups, these tools start feeling limited. pgBackRest is built for serious PostgreSQL backup requirements. Some of the reasons it stands out: Supports full, differential, and incremental backups Built-in compre...
