Read-Only Oracle Home Default

Read-only Oracle homes, where all configuration data and log files reside outside of the read-only Oracle home, are the default option for Oracle Database installations and upgrades.

Read-only Oracle homes enable an easy, flexible, and software-image based deployment of Oracle software that can automatically and seamlessly be distributed across multiple servers. Read-only Oracle homes also enable patching and updating of Oracle Database without extended downtime, as patching simply means replacing a given set of binaries in a defined location.
