ARCHITECTURE:
==============

ISSUE DETAILS :
Testing is failing for the following components

--> HSS Provisioning few roles is failing with error "apache bridge failure" or "Page cannot be displayed 400 error message"
--> Not able to connect to FR Studio using BIG IP URL or either OHS physical URL
--> After launching Webanalysis Login page when trying to login its giving " Page cannot be displayed 400 error message"
--> HFM Sample application creation from workspace is taking long time and getting timed out.
--> OHS is not able to connect to any of the manage servers on windows MT box, For the applications deployed on windows manage server it is failing with "apache bridge failure error message"
--> Here OHS is running on linux and HSS on windows machine, I am able to test other components running on linux machine - PCM, Planning (able to create the application successfully)
--> I am able to connect to FR Studio using the ManageServerIP:ManageServerPort , and I am able to provision all roles without any issues when i login to workspace using ManageServerIP:ManageServerPort, So this tells there is no issues with component wise.


--> OHS port is opened from windows(HSS) server to linux (OHS) server and All manage server ports running on windows server is opened from OHS box.
--> Tried reconfiguring OHS but still same issue and also tried enabling weblogicplugin on windows domain, But still same issue

Solution:

Suggested:
uncomment the following lines in the mod_wl_ohs.conf file on the OHS server:

Debug ALL
WLLogFile /tmp/weblogic.log

stop/start OHS retest HSS URL via port 19000 and check the /tmp/weblogic.log file for where the plugin is trying to send traffic to.


Implemented:
 After enabling the DEBGUG ALL option

The following error message was occurring in the debug log file

2013-08-08T07:45:06.1439-05:00 <13082137596590645> Error 13 in opening temp request body file '/tmp/_wl_proxy/_post_13082_0'

Final Solution: changed the file permission of /tmp/_wl_proxy/ file.
