Tech Tip : CA Single Sign-On : SPS is slow to load Certificates at Start Time

Discussion created by Patrick-Dussault Employee on Sep 27, 2016

Issue :


On the first request sent to the SPS server, the request takes
1 mn 30 seconds to process. The SPS needs this time to
load all certificates to communicate with the Backend Server.


Environment :


SPS 12.52SP1CR04 on RedHat 6 64bit




Certificates involve encryption that needs entropy, not enough entropy on the system


Resolution :


The Red Hat operating system relies on entropy for its performance.
On the OS, use the following command to make SPS using /dev/urandom
instead of /dev/random :


mv /dev/random /dev/


ln -s /dev/urandom /dev/random


You can also look to run the rngd service in order to get enough
entroy on /dev/random
