On AIX TLSv1.3 is Not Enabled for SSL Ports during WebLogic Server Startup (Doc ID 2821774.1)

Last updated on AUGUST 07, 2023

Applies to:

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


When starting WebLogic Server on AIX with IBM JDK the TLSv1.3 is not being enabled for the SSL port . This was verified by using sslscan and openssl tools.


The IBM JDK 1.8 SR6 SP25 and above have TLSv1.3 enabled as per IBM documentation so made sure that the JDK being used was higher that this version. 

Tried adding the following recommended JDK options as per IBM documentation and those also did not help.

-Djdk.tls.server.protocols=TLSv1.3 -Djdk.tls.client.protocols=TLSv1.3 -Dhttps.protocols=TLSv1.3 -Djdk.tls.server.cipherS
uites="TLSv1.3 CIPHERS"
