Getting Started with Oracle WebLogic Server: How to Make Sure that Recommended Patches are Applied (Doc ID 1365205.1)

Last updated on OCTOBER 15, 2020

Applies to:

Oracle WebLogic Server - Version 9.0 to 12.1.1.0
Information in this document applies to any platform.

Purpose

Customers frequently want to know what patches we recommend for WebLogic Server (WLS). As a rule, most WLS patches are one-offs, intended to solve a specific problem, and intended to be applied only when your system is experiencing that problem. However, some patches are more broadly applicable: they might fix a problem which many customers experience, might be particularly critical, or might resolve a security vulnerability, for example. We want to make sure that everyone gets these highly recommended and critical patches into their environment as soon as possible.

These highly recommended and critical patches are packaged into PSUs (Patch Set Updates) in WLS 10.3.4 and higher, and in CPUs (Critical Patch Updates) in earlier WLS versions. Oracle strongly recommends that all customers apply all of these patches to make sure that your system is secure and runs smoothly.

NOTE: See "Announcing Oracle WebLogic Server PSUs (Patch Set Updates)" <Note 1306505.1> for more information about PSUs and CPUs in WebLogic Server. See <Note 859115.1> for more about the Recommended Patch Advisor in My Oracle Support. Finally, note that this procedure has changed in WebLogic Server 12.1.2 and higher, where Smart Update has been replaced with OPatch.

This article will guide you through ensuring that your WebLogic Server environment has all the recommended patches in place.
