1) After configuring WebLogic to use stronger cipher suites (as per doc #660309.1), users can no longer access the PeopleSoft application from their browser. Instead, the following occurs when attempting to access the PeopleSoft application:
a. Browser hangs and never gets to sign on page
b. User gets a "Cannot display the web page" message

The gateway log only shows the generic error: Integration Gateway: No Response received from Gateway(158, 10829) and The Gateway did not send back a IBResponse. The Weblogic logs however contain the ‘Cipher not initialized ‘ as outlined below.
When this issue occurs, the WebLogic PIA logs show one of the following messages (messages will vary depending on the OS, Cipher Suite(s) and SSL library you are using):
