I am new to SES, I installed the latest ses11g, during installation, I found it's quite an automatic process, there was seldom intervention needed, and I briefed the admin guide, I found some questions here:
1. How to use Oracle RAC with SES?
Seems during installation, there is no way to do it
After installation, change jdbc pool from wls console to point to a rac url? but how to migrate tables already created during installation? migrate it by using db export/import tool?
2. Can we use 2 wls with 1 backend oracle db instance?
This is a typically failover scenario, but I didn't find document for this. To implement it, I can install another SES, then change the second wls admin server to use database which is used by the first admin server, is this a doable approach?
SES in it's current form is provided as a software appliance. It can only use it's own database and WLS. You cannot install against a RAC database.
For high availability, Oracle recommends running two identically-configured SES instances in parallel.
