Starup of active dataguard in RAC

Question

Hi,
i have a setup of active dataguard in RAC. This is my first time implementing dataguard in RAC.
Primary - RAC
Standby - RAC with active dataguard
when ever standby server(anyone of the RAC instance) reboots it is getting till mount state. And after that how can i get the database be opened and put in recovery mode to do redo apply.
I tried to push manual script as a startup script . Intially i kept sleep command for 15-20min and then connect to db instance and try to recovery from mounted database. But my mounted database is taking 15-30min to comeup once the server is rebooted.
please help me how we configure startup statements once the RAC is in mount state(cluster is getting till this point) after server reboot.

Hello;
If you are not using Data Guard Broker you need to open the standby database and set it in read only mode and then start the managed recovery as shown below.
SQL> shutdown immediate;
SQL> startup
SQL> recover managed standby database using current logfile disconnect;
With broker its like this :
Stop redo apply with the following command from Data Guard Broker
DGMGRL> EDIT DATABASE '?' SET STATE='APPLY-OFF';
Open standby read-only via SQL*Plus
SQL> alter database open read only;
Restart redo apply via broker
DGMGRL> EDIT DATABASE '?' SET STATE='APPLY-ON';
