Update OS procedure / Java updates

Different OS updates:

recommended procedure (also it works without stopping the services, but is recommended to stop them first).

• Stop services with ver_stop command on the server (bash /etc/veridiumid/scripts/veridium_services.sh stop)

• Do os update or other operation

• Reboot servers – the services will start automatically

• Run check_services to see that all services are up and running (green), before going to next server.

  • Normally the services will go up in 3,4 minutes after a reboot.

You need to look specifically for elasticsearch – cluster in status green, cassandra – all nodes are in UN status, zookeeper – all nodes are up in the cluster – one leader and 2 followers.

Java update:

• Stop services with ver_stop command on the server (bash /etc/veridiumid/scripts/veridium_services.sh stop)

• do java update

• start services with ver_start command on the server (bash /etc/veridiumid/scripts/veridium_services.sh start)

• Run check_services to see that all services are up and running (green), before going to next server.

  • Normally the services will go up in 3,4 minutes after a reboot.
