1. Create a pfile SQL> Create pfile = '/opt/Oracle/initorcl. ora' from spfile;
2. Edit the initorcl. ora file and delete the configuration related to dataguard.
3. Start Database SQL> startup pfile = '/opt/Oracle/initorcl. ora' from the new pfile file initorcl. ora'
This time error ora-03113:

Solution:
Statup starts the database normally
Change the database protection mode to "maximum performance" SQL> alter database set standby to maximize; performance;
Start Database SQL> startup pfile = '/opt/Oracle/initorcl. ora' from the new pfile'
Create spfile SQL> Create spfile from pfile = '/opt/Oracle/initorcl. ora ';
Fault Cause:It is suggested that the database is in "Max available" maximize availability mode, but the related "protection configuration parameters" cannot be found"
