Two installed VCO instances are required to initiate replication.

  • The selected standby is put into a STANDBY_CANDIDATE state, enabling it to be configured by the active server.
  • The active server is then given the address and credentials of the standby and it enters the ACTIVE_CONFIGURING state.
When a STANDBY_CONFIG_RQST is made from active to standby, the two servers synchronize through the state transitions shown below.
