Reads             (Overview)

DESCRIPTION
The number of "Reads" displays the number of physical reads a transaction has 
issued since it was initiated. 


VALUES
"Reads" is a numeric value that is initialized to zero at the start of each
invocation of a transaction. "Reads" will roll over after reaching 2**32 - 1.


INTERPRETATION
A physical read means a read not found in the Sun MTP internal cache. The read 
may or may not require a disk access, depending on whether or not the 
operating system can find it in its buffer cache.


CONCLUSIONS
"Reads" indicates the total number of physical reads the current transaction
has issued to the Sun MTP VSAM database. The number is cumulative only for a
specific transaction. Note that the rows in the Overview Screen's KxScrolledList
are actually for Transaction Servers, not transactions. In other words, the 
value shown for "Reads" applies only to the transaction executed by a 
Transaction Server. The datapoint does not tally up "Reads" for all transactions
executed by a given Transaction Server.
