Failure of server APACHE bridge error - Internal Processing error when clicked on Logout button on Oracle Data Integrator /odiconsole

While navigating in the Oracle Data Integrator 11g instance (ODI 11.1.1.6.0) /odiconsole, observed few issues like:

- After login to /odiconsole, clicking on 'Search' intermittently returned "Failure of server APACHE bridge error - Internal Processing error"

- When clicked on Logout button in /odiconsole, similar error was observed. 

Issue resolved by creating missing WLTempDir directory as specified under mod_wl_ohs.conf
