So will "*alter database activate physical standby database" * open my db in Read-write mode + Primary Role ?

alter system set log_archive_dest_3='disable' scope=both; --> ### on Prod_stby
Now shutdown the MRP on standby ### prod_cascade *alter database activate physical standby database;* alter system set log_archive_config='(PROD,PROD_STBY)' scope=both; ### On prod & Prod_stby both
alter system set log_archive_config='(prod_cascade,prod_cascade_stby)' scope=both; ### for new standby for cascade .
