1. Main node back up and generate alternate database control files
Set the primary node for Force Logging mode (for two-way switching, it is recommended to set it to Force Logging mode) alter database force logging;
Set the primary node as archiving mode
Log in to the main node, perform database backup, and generate alternate database control files
