Oracle’s Critical Patch Update April 2023 Readiness

4 min readJul 19, 2023

Oracle issues an Oracle Critical Patch Update (CPU) that provides a collection of fixes for several security vulnerabilities. These patches address potential security vulnerabilities in Oracle products, including code and third-party components.

Every quarter, how should you plan for Oracle vulnerabilities? How can you save testing effort and time while avoiding critical defects in production?

What Is Patching?

Patching is Oracle’s most facile method of providing new features. Patches are unavoidable whether you manage an on-premise Oracle E-Business Suite (EBS) or a Cloud application environment.

The functions of patch applications include:

  • Resolving an outstanding issue
  • Including a new feature or function
  • Upgrading the maintenance level
  • Implementing product upgrades
  • Interoperability of technological stacks
  • Identifying the root source of the problem
  • Accessing online assistance

Oracle Patching Isn’t Always as Simple as You May Think

Patching is not a high priority in all organizations. In fact, it is frequently overlooked due to operational availability. Patching may be neglected when system architectures are overly complex, functionality is highly customized, or users lack knowledge of the patching procedure.

Oracle Critical Patch Update (CPU) May Not Be as Scary as You Think

The Oracle update for the April 2023 quarter includes 433 new security updates and 298 vulnerabilities in a variety of Oracle products. They are alarming because they may be remotely exploited without authentication (over a network without requiring user credentials to access them). As a result, Oracle strongly advises customers to update CPU fixes as soon as possible and prioritize them.

How to Balance the Cost, Time, and Risk of Oracle Patch Testing

Not all Oracle patch types require the same amount of attention when balancing risk, time, and expense. Only the most critical patches, depending on your particular Oracle environment, need to be tested.

1. Risk

Your most important decision as a test or release manager is determining what needs to be tested. You must also determine who needs to test, between IT and the business, in order to discover the most critical defects. The following points must be considered for risk mitigation:

  • How can you be certain that your testing is focused on the impacted areas?
  • Are your business users testing too much or too little? Are they putting the proper things to the test?
  • Are you reliant on your database administration (DBA) staff?

2. Time

Here are some time-consuming activities while applying a new Oracle patch:

  • Capturing the new functionality introduced by the patch and educating the organization.
  • Identifying the right people to validate the impact of a vendor change on current customizations.
  • Identifying undocumented customizations and integrations
  • Understanding and prioritizing patch impact on critical business processes based on usage.

3. Cost

The main problem, as with any project, is to release faster while minimizing excessive costs. Business analysts devote a significant amount of time to assessing the impact and estimating the cost of a patching project. For a low-cost approach, you can perform only business-critical testing before deploying the release. This testing can be carried out by leveraging your business users as testers.

Follow the Oracle patching testing guidelines to act quickly during the next update and reduce your chance of a security breach.
