Read Rec          (DCT Extra, Intra)

DESCRIPTION
"Read Rec" displays the record number of the last item read from a transient 
data (TD) queue by an application program.  


VALUES
The value of "Read Rec" is a numeric value representing the sequence number of 
a record on a TD queue. If an item has never been put on a TD queue, "Read Rec"
displays nothing.


INTERPRETATION
In general, the value of "Read Rec" should increase as application programs 
take records from a TD queue. Watch this column over successive Sun MTPScan updates
to determine the amount of read activity for a particular TD queue.


CONCLUSIONS
When "Read Rec" keeps a single value for an extended period of time, make sure 
that the application programs are supposed to refrain from accessing data from 
a particular TD queue. When running programs that make heavy use of TD, little 
or no change with "Read Rec", along with "Write Rec", and their associated 
access time datapoints, may indicate application programming flaws.
