Baba, Each cas server will start its own hazelcast node (no need to install). Hazelcast has some capability to maintain itself if a node goes down (and comes up). I have not tested that since it is a minor inconvenience for a user to log in again if a session is lost

Thank you Ray for your answer I would also like to know if hazelcast must be installed on each node and also for the instanceName which name should we choose? a name of a node where it must be different and we add it to the DNS if this is the case on the name (InstanceName) is down my nodes will no longer be accessible ????

Whatever you use for ticket storage has to be fast enough so that the second server knows about the tickets before they are validated by the services. On my local I use apache config for clustering (this config will work with only one of the cas servers started). <VirtualHost *:443> <Proxy balancer://cascluster> # BalancerMember http://localhost:8087 BalancerMember ajp://localhost:8010 BalancerMember ajp://localhost:8011 </Proxy> DocumentRoot "/var/www/html" SSLEngine on SSLCertificateFile /etc/ssl/certs/local.uvic.ca.chain.pem SSLCertificateKeyFile /etc/ssl/private/local.uvic.ca.key.pem SSLProxyEngine on #Bypassing certicate checking on self-signed client cert SSLProxyVerify none SSLProxyCheckPeerCN off SSLProxyCheckPeerName off SSLProxyCheckPeerExpire off ProxyPreserveHost On ProxyPass /cas balancer://cascluster/cas ProxyPassReverse /cas balancer://cascluster/cas #ProxyPass /cas ajp://localhost:8010/cas #ProxyPassReverse /cas ajp://localhost:8010/cas ProxyPass /cas-management ajp://localhost:8017/cas-management ProxyPassReverse /cas-management ajp://localhost:8017/cas-management ProxyPass /sp ajp://localhost:8016/sp ProxyPassReverse /sp ajp://localhost:8016/sp ProxyPass /app0 http://localhost:12080/app0 ProxyPassReverse /app0 http://localhost:12080/app0 ProxyPass /app1 http://localhost:12080/app1 ProxyPassReverse /app1 http://localhost:12080/app1 ProxyPass /Shibboleth.sso http://localhost:12080/Shibboleth.sso ProxyPassReverse /Shibboleth.sso http://localhost:12080/Shibboleth.sso ProxyPass /nodejs https://localhost:8443 ProxyPassReverse /nodejs https://localhost:8443 ServerName local.uvic.ca<http://local.uvic.ca> <IfModule mod_headers> RequestHeader set X-HTTPS 1 Header set Referrer-Policy "no-referrer-when-downgrade" </IfModule> </VirtualHost> Ray On Fri, 2021-12-10 at 03:57 -0800, Baba Ndiaye wrote: Notice: This message was sent from outside the University of Victoria email system.
