ORA-09925

ORA-09925: Unable to create audit trail file

Quick fix

Cause: The instance could not write its audit file at startup or at SYSDBA login, because the AUDIT_FILE_DEST directory does not exist, is not writable by the oracle user, or the file system is full.
Fix: Create the directory named in AUDIT_FILE_DEST (from the pfile/spfile, or the default $ORACLE_BASE/admin/<db_name>/adump) with the right owner, and check free space.

mkdir -p $ORACLE_BASE/admin/$ORACLE_SID/adump
df -h $ORACLE_BASE

The audit directory must exist before the instance can start, otherwise you'll get ORA-09925.
