4. Cat Name—Modifiable by TCM administrators only
Cat Name is the name of the process category defined in MeasTCM on the NonStop host
system. (See “Process Category (PCAT) Statements” (page 53).) Up to 100 categories are
supported by MeasTCM.
5. Type—Not directly modifiable
Type is the type of a process category as defined in MeasTCM on the NonStop host system.
The maximum number of categories is 100 (including Other and Error).
The process category type consists of one of the following characters:
Server process—this category type grows with throughput.S
Requester process—this category type grows with throughput.R
Disk process—this category holds all nonaudited disk processes. There is only one process with this
category type.
D
TMF processes—this category holds all TMF-related processes, including the audit disk. TMF-related
processes must be identified in the Process Category Control File. For more information, see
“Customizing Your Process Category Control File” (page 33).
T
Line-handler process—this category type grows with throughput.L
Other—this category type grows with throughput.O
Fixed—this category includes system overhead that does not vary with throughput.F
Ignored processes (appropriate interrupt and disk activity to be omitted)—this category is ignored
and is used for activities that you do not expect to occur in the future. Use this category with caution
because you might unintentionally undersize a system.

CPU Workload Apportionment Screen
The CPU Workload Apportionment screen shows the apportionment of the CPU consumed by
process categories to transactions. Figure 35 (page 109) shows a sample CPU Workload
Apportionment screen.
