Data Integrity Level
Attribute
DataIntegrityLevel (DIL)
Purpose
Specifies a preference for the data integrity to be used on data sent between the driver and the database server. The connection fails if the database server does not have a compatible integrity algorithm. See Encryption and Data Integrity for more information.
Valid Values
Rejected | Accepted | Requested | Required
Behavior
If set to 0 - Rejected, a data integrity check on data sent between the driver and the database server is refused. The connection fails if the database server specifies REQUIRED.
If set to 1 - Accepted, a data integrity check can be made on data sent between the driver and the database server. Data integrity is used if the database server requests or requires it.
If set to 2 - Requested, the driver enables a data integrity check on data sent between the driver and the database server if the database server permits it.
If set to 3 - Required, a data integrity check must be performed on data sent between the driver and the database server. The connection fails if the database server specifies REJECTED.
