Last updated on APRIL 05, 2012

Applies to:

Oracle Secure Global Desktop - Version: 4.5 to 4.61 - Release: 4.0 to 4.0
Information in this document applies to any platform.

Symptoms

Windows clients may report expired and/or untrusted security certificate warnings coupled with high CPU consumption attributed to ttc binary after attempted authentication to Secure Global Desktop (SGD), with security functionality enabled as outlined in the Administration Guide, on the Oracle Technical Network.  

Note: The following example is specific to Microsoft IE 7.0.  Later versions of IE, or Firefox, may present slightly different results.

Example Scenario:

1) The connecting user enters the URL address for the SGD server in their browser
      --> The default SGD home page is seen.

2). The user selects the Log In button, and is redirected to the login page.

3) The user enters their login credentials and attempts to login.

At this point, the process "tcc.exe" may be observed on the connecting Windows PC to consume 50% or greater of the CPU.

4) After 5 minutes of waiting, a Certificate warning is seen stating that the Security Certificate has expired.

5) Another 5 minutes passes and the tcc.exe is still shown to be spinning at 50% or more.  At this point, a second Certificate message may be shown, warning the Certificate is untrusted, and allowing the user to accept the Certifiicate chain.

6). The user will find that accepting the chain then brings up the SGD Webtop, as expected, and operation will resume normally.
