Study Notes

Oracle Patch Types Overview

Patching is crucial for maintaining the security, stability, and performance of Oracle databases and applications.
Oracle releases different types of patches organized in a "patching matrix."

Types of Patches

Critical Patch Updates (CPUs)
- Released quarterly, targeting security vulnerabilities across Oracle products.
Patch Set Updates (PSUs)
- Cumulative patches released quarterly, including security and a small number of non-security bug fixes.
Release Updates (RUs)
- Quarterly updates that encompass security fixes, bug fixes, and minor feature enhancements.
Release Update Revisions (RURs)
- Provide critical fixes for specific RUs, allowing time for planning upgrades while maintaining security.
Interim or One-off Patches
- Address critical issues needing immediate attention, provided outside the regular patch cycle.
Bundle Patches
- Combine multiple one-off patches into a single package, often used in systems like Oracle Exadata.
Security Alerts
- Issued when severe vulnerabilities are discovered, requiring immediate patching outside the scheduled CPUs.
Diagnostic and Tuning Patches
- Designed to collect diagnostics or improve database performance, aiding Oracle Support with investigation tasks.
Diagnostic Assistant Tools and Utilities Updates
- Enhancements or new tools for better management and troubleshooting, independent from main patches.

Understanding the Patching Matrix

The patching matrix helps determine applicable patches based on database version, operating system, and specific needs.
It includes guidelines to ensure compatibility and stability across different system configurations.

Common Errors During Patching Activities

Pre-Check Errors
- Critical to ensure all prerequisites are met before applying patches, including:
  - Missing operating system packages.
  - Insufficient user privileges.
  - Conflicts with existing patches.
  - Outdated software versions that do not meet patch requirements.
