Pythian Group

I would like to share with you the virtual hosts set-up (two nodes each on the application tier, and two on the DB tier) for a customer using 11.5.9.

The Facts

• DB Version: 10.2.3
• CRS Version: 10.2.0.3
• ASM Version: 10.2.0.3
• APPS Version: 11.5.9

Set-ups by Sys-Admins

Sysadmins must set up a virtual hostname amongst the two available middle-tier (Applications) hosts. In our case, the hostnames are erpapp01, and erpapp02. Then the sysadmins set up a VIP as erpapp.

We also require from sysadmins virtual hostname amongst the two available backend (database) hosts. Hostnames in our case are erpdb01, and erpdb02. They then set up a VIP as erpdb. Read the rest of this entry . . .
