Last updated on MARCH 12, 2021

Applies to:

Oracle WebLogic Server - Version 9.2 and later
Information in this document applies to any platform.


For development, deployment within intranet, customer may expect to build a experimental PKI infrastructure with OpenSSL instead of commercial vendor, since they have full control of the Certificate Authority distribution. This practice gives detailed instruction to generate 3-tier certificate chain, and how to configure them to support 2-way SSL authentication against WebLogic.
