Transaction Count table
A table that defines how TCM should calculate the number of transactions from process category
performance data. The table specifies how to compute the number of transactions from the number
of messages process categories that receive, send, or both. This table is created and modified only
by users with a TCM administrator or superuser authorization level.
WA model
The Workload Apportionment component of TCM. The WA model is used to apportion process
category performance data (as collected on the NonStop host system using MeasTCM) into
transaction-oriented performance data. Data apportioned by the WA model can be loaded into
the Performance model for making capacity planning projections.
workload apportionment
The allocation of the CPU and disk read and write seconds, consumed by process categories, to
transactions.
Workload Summary
A Workload Apportionment (WA) model screen that summarizes the results of workload
apportionment and displays the CPU and disk seconds for each transaction. It also indicates the
fixed consumption per second.
