1.24 AUDIT_SYSLOG_LEVEL

AUDIT_SYSLOG_LEVEL allows SYS and standard OS audit records to be written to the system audit log using the SYSLOG utility.

Property Description

Parameter type

String

Syntax

AUDIT_SYSLOG_LEVEL = 'facility_clause.priority_clause'

Syntax

facility_clause::=

{ USER | LOCAL[0 | 1 | 2 | 3 | 4 | 5 | 6 | 7] | SYSLOG | DAEMON | KERN | MAIL | AUTH | LPR | NEWS | UUCP | CRON }

Syntax

priority_clause::=

{ NOTICE | INFO | DEBUG | WARNING | ERR | CRIT | ALERT | EMERG }

Default value

There is no default value.

Modifiable

No

Modifiable in a PDB

No

Basic

No

Examples

 
AUDIT_SYSLOG_LEVEL = 'KERN.EMERG';
AUDIT_SYSLOG_LEVEL = 'LOCAL1.WARNING';

Note:

In an Oracle database that has migrated to unified auditing, the setting of this parameter has no effect.

If you use this parameter, it is best to assign a file corresponding to every combination of facility and priority (especially KERN.EMERG) in syslog.conf . Sometimes these are assigned to print to the console in the default syslog.conf file. This can become annoying and will be useless as audit logs. Also, if you use this parameter, it is best to set the maximum length of syslog messages in the system to 512 bytes.

Note:

Audit records written to the system audit log could get truncated to 512 bytes, and different parts of the same audit record may not be joined to get the original complete audit record.

Oracle Database Security Guide for information about configuring syslog auditing

If AUDIT_SYSLOG_LEVEL is set and SYS auditing is enabled (AUDIT_SYS_OPERATIONS = TRUE), then SYS audit records are written to the system audit log. If AUDIT_SYSLOG_LEVEL is set and standard audit records are being sent to the operating system (AUDIT_TRAIL = os), then standard audit records are written to the system audit log.

In a CDB, the scope of the settings for this initialization parameter is the CDB. Although the audit trail is provided per PDB in a CDB, this initialization parameter cannot be configured for individual PDBs.
