There are couple of underscore parameters (starting with _IMR) and you
can try lower values. I think the default for split brain resolution is
10 mins and the reconfig delay is 5 mins. 

Just set the values in a test environment and see if that helps. You
may want to check with Oracle Support for official recommendations.
