CPU/PSU Patching

A Critical Patch Update (CPU) is a collection of patches for multiple security vulnerabilities. Critical Patch Updates are cumulative for many Oracle products. This means that, for these products, a CPU includes new security fixes as well as all previously released CPU fixes for this particular platform and version combination. The main benefit of cumulative CPUs is that it allows customers to quickly and easily “catch up” to current security release level by only applying the most recent CPU

Since the inception of the Critical Patch Update program, Critical Patch Updates were released on the Tuesdays closest to the 15th of the months of January, April, July, October. CPU patching program delivers two following goals

  • Providing Oracle customers with a cost effective security vulnerability remediation program, and
  • Maintaining the best possible security posture for Oracle customers before and after the release of the security fixes by Oracle.

eBiZure strongly recommends that customers remain on actively-supported versions and apply Critical Patch Update fixes without any delay. eBiZure DBA team can prepare a customized CPU patch protocol for your environments once you decide to apply these patches complying with Oracle’s recommendations. The patch protocol will be prepared based on the products/modules licenced and will be applied to your environments based on your environment promotion policies before they are applied to production.
