PDF Reports show blank screen with SSO and SSL protection

Oct 9, 2012

When running Oracle Reports using the HTTPS protocol as well as with SSO protection through OAM, there is a known issue in the Internet Explorer (IE) 7 and 8 browsers where PDF reports either appear blank or an “Internet Explorer cannot display the webpage” error appears. This is a browser-related error in older versions of IE. To fix the problem, you will need to do the following:

  1. Make a backup of httpd.conf located in %ORACLE_INSTANCE%\config\OHS\ohs1\httpd.conf
  2. Open httpd.conf in a text editor (WordPad preferred)
  3. At the very bottom of the file, add in the following line: Header unset Pragma
  4. Save and close the file
  5. Restart OHS using OPMNCTL

The report should now display successfully.
NOTE: Internet Explorer 9, Mozilla Firefox, and Google Chrome do NOT have this problem.
