public final class StatisticsMessageTypeV1_0
extends StatisticsMessageType

The StatisticsMessageType is used for instructing the server monitor to do a DBVERIFY on a relvar.

This message type has the following fields :

Field detail

Zone	Format	Length	Description
USERID	STRING		The name of the user issuing the monitor command. Can be the zero-length string, but if not, it must be a name that appears in some tuple of the USER relvar.
AUTHBYCLIENT	INTEGER	1	1 if the client has authenticated the user, 0 otherwise.
AUTHALGORITHM	STRING		The name of the signing algorithm used to compute SIGNATURE. Can be the zero-length string.
SIGNATURELENGTH	INTEGER	2	The number of bytes in SIGNATURE. Can be zero, in which case the SIGNATURE field is omitted from the message.
SIGNATURE	BYTES		The signature as computed by the signature algorithm identified by AUTHALGORITHM, using the user's private key corresponding to the public key that is registered for the user in the USERCERTIFICATE relvar, and applied to the CHALLENGE field obtained from the preceding ServerHello response message.
RELVARNAMELENGTH	INTEGER	2	The number of bytes in RELVARNAME.
RELVARNAME	BYTES		The name of the relvar on which statistics are to be gathered, as encoded by the NAME type implementation.
