I have Dataguard setup in RAC environment and my dataguard is also configured and it is working fine.
Our goal is to do the switchover using DGMGRL withing the 5 minutes. We have followed the proper setup and MAA tuning document and everything is working fine, Just the switchover timeing is 8 to 10 minutes. which varies depending on some parameters but not meeting our goal of less than 5 minutes.
The only observation that we have seen is as follow
After switchover to <db_name> comman in DGMGRL
1) it will shutdown abort the 2nd instance
2) transfter all the archivelog ( using LGWR in ASYNC mode) of instance 1
