Operation Audit

audit_system_object

Parameter description: Specifies whether to audit the CREATE, DROP, and ALTER operations on database objects. Database objects include databases, users, schemas, and tables. The operations on the database object can be audited by changing the value of this parameter.

This is a SIGHUP parameter. Set it based on instructions provided in Table 1.

Value range: an integer ranging from 0 to 536870911

  • 0 indicates that the function of auditing the CREATE, DROP, and ALTER operations on database objects can be disabled.
  • Other values indicate that the CREATE, DROP, and ALTER operations on a certain or some database objects are audited.

Value description:

The value of this parameter is calculated by 29 binary bits. The 29 binary bits represent 29 types of database objects. If the corresponding binary bit is set to 0, the CREATE, DROP, and ALTER operations on corresponding database objects are not audited. If it is set to 1, the CREATE, DROP, and ALTER operations are audited. For details about the audit contents represented by these 29 binary bits, see Table 1.

When SQL patches are audited and audit_dml_state_select are enabled, an SQL patch operation will be audited twice and recorded as DML and DDL operations in the audit log, respectively.

Default value: 67121159
