Redo log corruption caused by gathering database stats on 12c

edited Aug 23, 2020 5:04AM in Database ORA-600 / ORA-7445 Analysis , Diagnostic Repository (ADR) & Packaging (MOSC) 1 commentAnswered

A test database crashed with the below errors after gathering database stats.

The crash was caused at the same time database stats were running. Oracle support are unable to explain why this has happened

The database was lost and required a restore.

the test database was not in archive log mode and the database had to be cloned again from production? Oracle support have been unable to explain why this has happened.  Errors in file /opt/oracle/UCGBODC2/diag/rdbms/ucgbodc2/UCGBODC2/incident/incdir_336842/UCGBODC2_m000_77890_i336842.trc:
