Usage The number of times that this particular EXEC CICS command (with the transaction, program, and offset values reported) taking part in the affinity, up to a limit of 5000.

Note: The usage count is an indication of the relative importance of the affinity, and is not a completely accurate usage count. For performance reasons, when the usage count is incremented by the Detector, the ªsave to ®leº ¯ag is not necessarily set to indicate that the record needs to be saved to the data ®le. The save ¯ag is set as follows:

0<= usage count < 10, save flag set every increment

10<= usage count < 100, save flag set every 10 increments

100<= usage count < 5000, save flag set every 100 increments

 

5000 <= usage count,

neither increment nor save flag set

 

If the usage count is '1+', it means that at least one example of the affinity

 

was seen but that the total number of occurrences of that affinity is

 

unknown.

 

 

Terminal

 

 

Whether this particular EXEC CICS command (with the transaction,

 

program, and offset values reported) was ever issued by a transaction

 

initiated from a terminal; that is, started as a result of terminal input or for

 

an EXEC CICS RETURN TRANSID command. (This does not include

 

ATI-started transactions.)

 

The word Mix in this column is used to indicate that a particular EXEC

CICS command was issued by a transaction initiated from a terminal and

also issued by the transaction when it was initiated with no associated

terminal.

 

BTS Task

 

Whether it is a CICS BTS task or not.

Total Transactions

The total number of different transactions in the affinity transaction group.

Total Programs

The total number of different programs in the affinity transaction group.

Producing affinity transaction group de®nitions

The Reporter produces affinity transaction group de®nitions suitable for input to the Builder (but not to CICSPlex SM). Each de®nition consists of a unique transaction group name, a relation, a lifetime, and a set of tranids.

Not everything that appears in the report appears as an affinity transaction group. In particular, transaction-system affinities do not appear, because they are not of interest to a dynamic routing program; nor do transactions that were not initiated from a terminal (for the same reason).

Figure 9 on page 47 shows a sample set of de®nitions to match the report in

Figure 8 on page 43.

Notes:

1. The transaction group name is not a valid CICSPlex SM transaction group name, because the latter must be eight characters; it is used only as a cross-reference to the report.
