Some Back ground.
HP-UX 11.11 on superdomes running under SG cluster.(A.01.02)
Node-1 runs Apache web server and OAS. Node-2 runs Oracle 8.1.7(db server)
Node-3 also running apache and OAS.
Now network team is planning to put one firewall between clustered nodes. i.e node-1 running apache,OAS and node-2-oracle db server.
Info required.
What measures/precautions do I need to take for proper operation of SG environment.
(please note that node-3 is not under SG, but just a load balancing server for node-1)
What ports do I need to open, and more importantly what precations do I need to take under SG environment.
Does anybody have same setup?
node-2 database server gets request from node-1 and node-3.
Thanks in advance.
