Depending on your OS configuration and how tight it is - you may be or not
be able to use an external table and load the syslog file using the oracle
loader.
Here's a practical example how you could do that:

We did some testing and I got some further clarification.
Apparently the requirement is that all auditing be logged to the syslog
file. The DBA on the project tried various settings and could not get it to
populate both syslog and v$xml_audit_trail (see below for test results).
Is there some setting we missed trying or is this just not possible?
And if not possible, does anyone have an easy way to query the syslog file?
Thanks!
setting 1 -
audit_file_dest string /app/oracle/diag/adump
audit_sys_operations boolean TRUE
audit_syslog_level string LOCAL7.INFO
audit_trail string XML
unified_audit_sga_queue_size integer 1048576
1. Setting audit_trail = XML creates xml audit entries under
audit_file_dest location and so it shows with v$ view.
It does not create audit entries in syslog directory (in this case it
is under /app/oracle/diag/syslog).
But since audit_sys_operations = TRUE, all sys operations (i.e. local)
are stored in the syslog file
setting 2 -
audit_file_dest string /app/oracle/diag/adump
audit_sys_operations boolean TRUE
audit_syslog_level string LOCAL7.INFO
audit_trail string XML, EXTENDED
unified_audit_sga_queue_size integer 1048576
1. ran 'create user....' and i see the record in the syslog file (under
/app/oracle/diag/syslog), but not in the XML file under audit_file_dest and
not in the v$ view
2. ran 'drop user....' and i see the record in the syslog file (under
/app/oracle/diag/syslog), but not in the XML file under audit_file_dest and
not in the v$ view
setting 3 -
audit_file_dest string /app/oracle/diag/adump
audit_sys_operations boolean TRUE
audit_syslog_level string LOCAL7.INFO
audit_trail string OS
unified_audit_sga_queue_size integer 1048576
1. no records under audit_file_dest (expected) and no records in v$
view(expected) for any audit (sys or other audit items like create/drop
user, etc.)
2. ran 'create user, drop user' and all showed in the syslog file

Thank you! We’ll test that out (and cross our fingers that the format is
acceptable to the security folk).

We send our audit trail to xml audit trail files. We then query it
from v$xml_audit_trail

We have just been given the requirement to move our auditing from database
to OS and I was wondering how other people have handled obtaining the data
which is currently easily available from dba_audit_trail.
For example things like getting a histogram of login times to see if there
was a sudden surge in connect activity or finding the name of an app server
which is locking an account by sending invalid passwords. Really easy now
but with OS files? How are other people handling this?
I’m told all the information will be available in Splunk though I have no
idea how easy that will be to access.
TIA,
Jay Miller
