I/O THRESHOLDS - MIN nK HIGH n LOW n OS n DB24 n

Reason:

This message is generated at two-minute intervals if the value of the MUF startup option X_IO_MSG_THRESHOLD was set to its maximum value of 1048576. The meanings of the variables in the message text are as follows: Take into account that the delta values are those from the end of the two-minute period.

MIN nK

The lowest available memory seen at the start of a CA Datacom/DB I/O. If no I/O was started, -NO I/O is displayed.

HIGH n

The count of times the MUF constrained I/O because of the high threshold.

LOW n

The count of times the MUF constrained I/O because of the low threshold.

OS n

The count of times the MUF constrained and started no I/O because of the operating system limit on maximum outstanding I/O.

DB24 n

The count of times I/O was constrained because the amount of 24-bit memory used by CA Datacom/DB was above the threshold defined by the MUF startup option X_IO_24BIT_SIZE.
