Dear All,

I’m using keycloak **16.1.1** in dockers. we have two separate servers and we hare facing token invalid once server restart. After doing research we found the solution for that. Since we have **100k** user base we like to apply those env variables without restarting both keycloak due to users logout.

Those are the env variables we need to add our production env

_CACHE\_OWNERS\_COUNT=2_  
_CACHE\_OWNERS\_AUTH\_SESSIONS\_COUNT=2_  
_JGROUPS\_DISCOVERY\_PROTOCOL=JDBC\_PING_  
_JGROUPS\_DISCOVERY\_PROPERTIES="datasource\_jndi\_name=java:jboss/datasources/KeycloakDS_

I’m looking for advice, how to do it using CMD or cil.

Thank you.
