Here is a roadmap including the required documentation references, which can be used to build the configuration that I call "High available EBS 12.2 configuration provided by a Shared Application Filesystem, Oracle RAC infra and a Load Balancer"
Actually, I m currently installing a 4 node EBS 12.2 environment and in couple of days, I will document it as a whole.
Anyways, I still wanted share the action plan with you.
Actions:
1) Install Grid 12.1 and build a RAC environment.
2) Install EBS database using rapidwiz. Install it as a RAC database.
3) Install EBS Apps Tier in to a single apps server (primary apps server) , upgrade it to the supported release (currently 12.2.6)
4) Export the necessary directories from the primary apps server using NFS
5) Mount these exported directories in the secondary apps server.
6) Follow the standard Oracle Support documents (mainly Sharing The Application Tier File System in Oracle E-Business Suite Release 12.2) and add the secondary apps server to the topology.
7) Follow EBS Load balancer document and enable the load balancer. (Note 1375686.1 - Using Load-Balancers with Oracle E-Business Suite Release 12.2)
8) Do post installation work and tune the configuration (Enable SSL, configure PCP etc..)
Actions from a different point of view:
1) Install Grid infra 12.1

8) Do post installation work and tune the configuration (Enable SSL, configure PCP etc..)
Actions from a different point of view:
1) Install Grid infra 12.1
2) Install EBS database tier as a RAC database using startCD 51
4) Perform a full rman backup
5) Do the database post installation work -> Using Oracle 12c Release 1 (12.1) Real Application Clusters with Oracle E-Business Suite Release R12.2 (Doc ID 1626606.1)
"Section 5.2.2 Post Install Steps"
6) Execute rapidwiz on 1 st (primary) apps node and load the configuration from db to install EBS 12.2.0 apps tier.
7) Upgrade EBS to 12.2.6 and apply the translation+localization patches (if required)
8) Follow -> Sharing The Application Tier File System in Oracle E-Business Suite Release 12.2 (Doc ID 1375769.1) to add a secondary application server to the configuration.
"do the things documented in Section 3.3 Execute adpreclone Utility on the Run and Patch File System" and afterwards
9) Enable load balancer by following -> Using Load-Balancers with Oracle E-Business Suite Release 12.2
10) Enable Parallel Concurrent Processing - > Using Oracle 11g Release 2 Real Application Clusters and Automatic storage management with Oracle E-Business Suite Release 12.2 (Doc ID 1453213.1) (I m giving the 11gR2 document for this, because enabling PCP is not documented in the document named Using Oracle 12c Release 1 (12.1) Real Application Clusters with Oracle E-Business Suite Release R12.2 (Doc ID 1626606.1)) : Appendix I : Configure Parallel Concurrent Processing
Some of the key requirements:
*All database node must be at the same OS level (same OS patch level)
*All application node must be at the same OS level (same OS patch level)
*NFS must be installed on apps nodes
*ssh equivalency must be configured for apps to apps and db to db nodes.
*Grid 12.2 is not certified with EBS. (EBS database version delivered with latest start cd (startCD 51) is 12.1 and RDBMS 12.1 has critical issues with GRID 12.2. So GRID 12.1 should be used.
Things to know for Multi node installation:
4) Perform a full rman backup
5) Do the database post installation work -> Using Oracle 12c Release 1 (12.1) Real Application Clusters with Oracle E-Business Suite Release R12.2 (Doc ID 1626606.1)

Things to know for Multi node installation:
- Rapidwiz no longer supports multi node apps tier installation.
- In order to have a multi node apps tier; we install the apps tier as single node, then we upgrade the EBS 12.2 to the latest RUP levle (12.2.6) and then we add the secondary application node using standard cloning procedure.
- We use NFS for mounting the the APPL_TOP, COMMON_TOP, OracleAS 10.1.2 Oracle Home, Oracle WebLogic Server, and WebTier Oracle Home file systems from primary application tier to the secondary application node.
- Shared Application Tier File System can not be a read-only-file system unlike in the previous releases.
- For Solaris 11 installation, a modification in the installation stage files is required. .> http://ermanarslan.blogspot.com.tr/2017/07/ebs-1220-installation-on-solaris-511.html
