database instance crashed ORA-00221,ORA-00206,ORA-00202,ORA-15079
Hi All,
I have a 12C (ASM) database which crashed instantly due to the below errors. After checking the alert log files, I started the database and it opened fine.
What is the issue and how can I prevent it from occurring again?
ORA-00221: error on write to control file
ORA-00206: error in writing (block 3, # blocks 1) of control file
ORA-00202: control file: '+DATA1/TCAPPIC5/CONTROLFILE/current.460.904167565'
ORA-15079: ASM file is closed
ORA-15079: ASM file is closed
Can anyone shed some light on the issue?
