Last updated on SEPTEMBER 03, 2020

Applies to:

Oracle Forms - Version 11.1.2.2.0 to 11.1.2.2.0 [Release 11g]
Oracle WebLogic Server - Version 10.3.6 to 10.3.6
Oracle Reports Developer - Version 11.1.2.2.0 to 11.1.2.2.0 [Release 11g]
Oracle Fusion Middleware - Version 11.1.1.2.0 to 11.1.2.2.0 [Release Oracle11g]
Information in this document applies to any platform.

Symptoms

After installed new SHA2 certificate on Oracle Weblogic Server, SSL communication to WLS is failing. In this case, the OHS installed WLS Proxy Plugin is sending the request to WLS where the original request is originating from Oracle Forms / Reports use of the JRE client:


JRE Client --> HTTPS --> OHS/mod_wl_ohs --> HTTPS --> WLS

OHS log trace : 

  

  

 

SSL communication between the OHS and the WLS should work with SHA2 certificates.

Changes

1) Upgraded JDK from 1.6 to 1.7
2) Installed new SHA2 certificate on WLS
