I am upgrading the Instance from 188.8.131.52 to 12.1.3
I have 6 nodes
2 nodes for Database- sunclustered
2 nodes for Application Services-- connected with cisco load balancer
2 nodes for DMZ runing on web services --> connectd with another cisco load balancer ( for all imodules)
There should be two urls at the end 1 for internal users and another url for external users accessing outside the network.
I am planing to implement shared appl-top for all the 4 nodes..
during rapidwiz will provide all the 4 node information for 2 nodes all services enabled and for DMZ web nodes only web entry and root services enabled.
I confirmed from Oracle for my architecture I cannot have one shared APPL_TOP for all the four nodes.
So Oracle suggested to go with two shared APPL_TOP one for 2 internal nodes runing all services another one for 2 external web nodes i.e 2 DMZ nodes.
I need your inputs how to setup shared APPL_TOP for external nodes during addition of nodes.
During laying down of R12 file system I will use shared APPL_top for 2 internal nodes and then will upgrade till 12.1.3
then I am planing to implement and add 2 external web nodes. pls suggest how to do that.
Shared APPL_TOP cannot be shared between external web tier and internal middle tier if you are using seperate nodes for both.
If you are implemting an shared APPL_TOP between two external nodes then this an alternate topology as per note Oracle E-Business Suite R12 Configuration in a DMZ [ID 380490.1]. Please work with support.
I am aware of it that a single Shared APPL_TOP can be implemented between internal and external nodes.
I want to know how can I implement the another shared APPL_TOP for external web nodes.
Shall i copy the R12 file system to extermal mount points and run adcfgclone then add node.
I checked with support they said to work with experts in forums.
