According to the Bookshelf files of sps(https://support.ca.com/cadocs/0/CA%20SiteMinder%20Secure%20Proxy%20Server%2012%205-ENU/Bookshelf_Files/PDF/sps_rel_enu.p… ) we can see it supports httpd Apache 2.2.22 .But according to the requirement we need to upgrade the apache from 2.2. to 2.4.
Can anyone tell me if that is feasible and SPS will support this apache version and if so how can we upgrade it .
This is not supported.
I agree upgrading apache from prepackaged SPS is not supported.
However, if you upgrade SPS to later release R12.52sp1, you will get pre-build apache version 2.4.4
Under ~CA/secure-proxy/httpd/bin, run apachectl -V
