After Applying 184.108.40.206.170418 WinDBBP, SSL_RSA_WITH_AES_256_GCM_SHA384 in SSL_CIPHER_SUITES Cause SSL Connection Fail 'ORA-28865: SSL connection closed'
(Doc ID 2328841.1)
Last updated on APRIL 06, 2020
Applies to:Advanced Networking Option - Version 220.127.116.11 and later
Customer applied patches 25632533 (WINDOWS DB BUNDLE PATCH 18.104.22.168.170418) and 25590993 (WINDOWS ORACLE JAVAVM COMPONENT BUNDLE PATCH 22.214.171.124.170418) , and afterwards SSL connections no longer worked.
To fix the SSL connections to the database, I had to remove SSL_RSA_WITH_AES_256_GCM_SHA384 from the parameter SSL_CIPHER_SUITES.
