Script creates database properly, if set audit_trail='os' but it throws error if set audit_trail='db,extended'.

Error Log:

LRM-00121: 'db,extended' is not an allowable value for 'audit_trail'
ORA-01078: failure in processing system parameters

whether later it can be changed? will there be any issues, if doing so?

Please guide me in creating database through script with audit_trail='db,extended' in init.ora at the time of db creation.

Answer 1

Remove the quotes from around 'db,extended'

oracle:oklacity$ grep audit_trail initoklacity.ora
*.audit_trail='db,extended'

oracle:oklacity$ sqlplus / as sysdba
