Troubleshooting ORA-03113
On one occasion, when I was trying to insert data into the experimental environment, I finally burst ASM.
With ASMCA, the available space is actually-0.04GB.
At this time, shutdown abort, and then start, can only be mount state, as long as an open, will
ORA-03113: end-of-file on communication channel
(there may be many reasons for ORA-03113, improper setting of core parameters of the system, oracle environment variables and permissions, errors caused by SQL,PL/SQL, full disk space, firewall problems)
In this case, you can directly use RMAN to delete unnecessary archive logs on ASM.
Rman > connect target /
Rman > delete archivelog all
After clearing the space, start again, OK
