OMotion
OMotion moves a RAC-One instance from one serverto anotherwithout any downtime
Use Cases Load balancing
Server/OS patching and maintenance
Oracle supplied scripts control migration Services are not accepting connections on both nodes at thesame time
Migrated instance shutdown transactional once servicesmoved
A maximum of 30 minutes allowed for connections to migrate(then shutdown abort)
