Operation Auditing

audit_system_object

Parameter description: Specifies whether to audit the CREATE, DROP, and ALTER operations on MogDB database objects. MogDB database objects include DATABASE, USER, Schema, and TABLE. The operations on the database object can be audited by changing the value of this parameter.

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

Value range: an integer ranging from 0 to 268435455

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

Value description:

The value of this parameter is calculated by 26 binary bits. The 26 binary bits represent 26 types of MogDB 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 19 binary bits, see Table 1.

Default value: 67121195
