• Strengthen software security and address newly discovered vulnerabilities
• Improve stability and reliability through tested and supported releases
• Maintain compatibility with newer database, infrastructure, and operating system components
• Ensure access to the most effective Oracle Support diagnostic and resolution tools
• Remain eligible for the latest fixes and enhancements

The rest of this chapter describes MAA software maintenance best practices for:

• Oracle Database
