I have installed EPM11121 succesful. But during configuration, EPM System Configurator reports I am failed to "Configure Web Server".
After checked the log file, I find the it says
Unable to start opmn


Actually it missing whole folder /OHS/ with its inside files from directory /EPMLocation/user_projects/epmsystem1/httpConfig/
my local folder only has
/u01/app/Middleware/user_projects/epmsystem1/httpConfig/ohs/config/OPMN/opmn (have)
/u01/app/Middleware/user_projects/epmsystem1/httpConfig/ohs/config/OHS/ohs_component/httpd.conf (not have)
It is very wired, because EPM installed successful it shouldn't missing files like OHS/ohs_component/httpd.conf
Configuration "Configure Web Server" failed.

Anyone know how to resolve missing folder /OHS/ohs_component ?
I have searched online, someone say it is because
"The installToo.sh is able to read TMPDIR variable set, however, OHS silent install reads TMP and TEMP. When either one of these locations does not have the minimum Oracle HTTP Server requires(which for 11.1.2 is 1.2GB (x2) available, it will fail"
But I checked my case, it has huge free space 67G. It couldn't be above reason?
How to solve this missing ohs_component problem?
