This article provides information on configuring APIX to use certain protocols during SSL communication.

For Facade/OAuthWebapps SSLConnection channels:

- APIX2.1.1 HF1 onwards, the following properties in asg.properties, can be used:

tibco.clientVar.DefaultImplementation/Connections/HTTP/FacadeHTTPSSLConnection/SSLServerProtocols=TLSv1,TLSv1.1,TLSv1.2
tibco.clientVar.DefaultImplementation/Connections/HTTP/OAuthWebappsSSLConnection/SSLServerProtocols=TLSv1,TLSv1.1,TLSv1.2

- Before APIX2.1.1 HF1, the channel had to be updated in ASGDefaultImplementation project and asg_core.ear rebuilt as required.

For communication between APIX and Target Services:

1). Edit the asg-engine.tra file.

2). Append the following Java property to java.extended.properties (change the values per requirement).
-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2

3). Restart the engine.
