What is the primary purpose of applying patches to Oracle databases?

• To fix bugs and address security threats

• To improve user interface

• To upgrade database versions

• To enhance database performance

What is the main difference between reactive and proactive patching strategies?

• Reactive patching is for new features, proactive is for bug fixes

• Reactive patching responds to specific issues, proactive is routine

• Reactive patching is scheduled, proactive is not

• Reactive patching is for security, proactive is for performance

What are interim patches in Oracle support?

• Patches for performance enhancement

• Patches for user interface improvements

• Patches for specific issues upon request

• Patches for new features

What significant changes have occurred in Oracle's patch delivery methods?

• Changes in naming conventions and version formats
