2.2.2.4.1.5 MSG_DTCUIC_STATS

The MSG_DTCUIC_STATS message is sent by the Management Server to the Management Client to report current statistical information about transactions (see section 3.3.6.1).

MsgHeader (24 bytes): This field MUST contain a MESSAGE_PACKET structure (as specified in [MS-DTCO] section 2.2.4.1). The dwUserMsgType field MUST be 0x00003001. The dwcbVarLenData field MUST be 84 plus the size in bytes of the timeTransactionsUp field.

cOpen (4 bytes): A 4-byte unsigned integer indicating the number of currently opened transactions.

cCommitted (4 bytes): A 4-byte unsigned integer indicating the current number of committed transactions.

cAborted (4 bytes): A 4-byte unsigned integer indicating the current number of aborted transactions.

cInDoubt (4 bytes): A 4-byte unsigned integer indicating the current number of in-doubt transactions.

cHeuristic (4 bytes): A 4-byte reserved field that MUST be set to 0x00000000.

cOpenMax (4 bytes): A 4-byte unsigned integer indicating the maximum value of the cOpen field since the transaction manager was started.

cCommittedMax (4 bytes): A 4-byte unsigned integer indicating the maximum value of the cCommitted field since the transaction manager was started.

cAbortedMax (4 bytes): A 4-byte unsigned integer indicating the maximum value of the cAborted field since the transaction manager was started.

cInDoubtMax (4 bytes): A 4-byte unsigned integer indicating the maximum value of the cInDoubt field since the transaction manager was started.

cHeuristicMax (4 bytes): A 4-byte reserved field that MUST be set to 0x00000000.

cForcedCommit (4 bytes): A 4-byte unsigned integer indicating the current number of transactions that were in doubt, and were forced to commit.

cForcedAbort (4 bytes): A 4-byte unsigned integer indicating the current number of transactions that were in doubt, and were forced to abort.

cAvgResponseTime (4 bytes): A 4-byte unsigned integer indicating the current average time in milliseconds for transaction committing.

cMinResponseTime (4 bytes): A 4-byte unsigned integer indicating the current minimum time in milliseconds for transaction committing.

cMaxResponseTime (4 bytes): A 4-byte unsigned integer indicating the current maximum time in milliseconds for transaction committing.

timeTransactionsUp (4 bytes): This field SHOULD contain either an unsigned 4-byte integer, or 4 bytes of padding (containing non-deterministic values) followed by an 8-byte unsigned integer in 64-bit Windows, that specifies the number of seconds that elapsed from a baseline time to when the service was started.<2> In the Windows implementation, the Management Client Role does not use this field. To distinguish between 32-bit and 64-bit Windows, the implementation can check the dwcbVarLenData field, which varies based on 32-bit and 64-bit implementations. The baseline time used for this field MUST be midnight January 1, 1970, Coordinated Universal Time (UTC).

systemTimeTransactionsUp (16 bytes): A SYSTEMTIME structure (as specified in [MS-DTYP] section 2.3.13) indicating the time when the service was started.

dwTimeStamp (4 bytes): A 4-byte unsigned reserved field that MUST be set to 0x00000000.

cSinglePhaseInDoubt (4 bytes): A 4-byte unsigned integer indicating the current number of transactions that have entered the single-phase in-doubt state.
