It might be useful to achieve what you're after.

From the docs:

"Note:
You could also set the database initialization parameter, DATA_GUARD_SYNC_LATENCY, which is global for all synchronous standby destinations. It defines the maximum amount of time (in seconds) that the primary database may wait before disconnecting subsequent destinations after at least one synchronous standby has acknowledged receipt of the redo.

For example, suppose you have three synchronous standby destinations and you set DATA_GUARD_SYNC_LATENCY to a value of 2. If the first standby acknowledges receipt of the redo immediately, then the primary database waits no longer than 2 seconds for the other two standbys to respond. If one or both respond within 2 seconds, then they are maintained as active destinations. Destinations that do not respond in time are marked as failed. In both cases the primary remains in zero data loss protection mode because one synchronous standby has acknowledged receipt of the redo. Any failed synchronous standbys are reconnected as normal after the number of seconds specified for the REOPEN attribute have passed"
