We encountered an issue when we tried to install a new instance on a new tie-breaker server.
All our dev instances are in R12 SP2 with last patch
When we tried to launch the install.bin on a new tie-breaker and select add instance it fails with the error :
The db is in a higher version
Release : 12.0
Component :
The recommended solution is to set the following environment variable before launching the setup to add instances :
# IA_AE_SKIP_DB_CHECK=1
# export IA_AE_SKIP_DB_CHECK
