The role switch transition is a multi-step operation which involves shutdown of both source and targets; mark the databases in transition state; update replication bootstrap information and a few others. The transition can also be configured for some optional actions such as recovery backup before the transition to prepare for a failure, enable/add AI extents during the transition, and restart the new source/target after the role switch etc. The transition command will initiate and perform all these actions on both source and targets according to the “transition” properties in replication property file. After the command completes, the former source will become the new target; and the former target the new source. Note that applications will still need to be redirected to the new source/targets -- it’s not part of this transition command. Dapeng
