log_archive_dest_3='location=/u03/app/oracle/oradata/11.2.0/xe/archive3'
log_archive_dest_state_1='enable'
log_archive_dest_state_2='enable'

如果设置，脚本会正确创建数据库，audit_trail='os'但如果设置则会引发错误 audit_trail='db,extended'。
错误日志：
LRM-00121: 'db,extended' is not an allowable value for 'audit_trail'
ORA-01078: failure in processing system parameters
以后是否可以改？如果这样做，会有什么问题吗？
请指导我在创建数据库时通过 init.ora 中的 audit_trail='db,extended' 脚本创建数据库。
