Various report detail lines quantify activity on the basis of the
PSW (Program Status Word) address values observed at the time of the
sample. One PSW observation is recorded for each TCB. Depending on
the report, the 'activity' might be: CPU usage, WAIT time, Queued
time, or overall service time.
The analysis reports classify the PSW address values and aggregate
them into 'objects'. The reports show each of these objects in one
detail line arranged in a hierarchy. Each successive level in the
hierarchy represents a more granular breakdown of the quantifications
reported in the higher level items.
These objects are reported with a Name field, a Description, a
quantification expressed as a percentage, and a histogram depicting
the quantity. Descriptions of these detail lines are presented here.
APPLCN - Application code category

about the transaction appears to the left, and a bar chart appears
to the right.
Under Heading |

or subsystems: DB2®, IMS™, CICS®, MQSeries®,
etc. SVC (Supervisor Call) routines and MVS™ Nucleus
routines are included in this category. |

module name could be determined. These measurements are aggregated
under the NOSYMB category. Each report line represents a 4K (4096
bytes) range of addresses. The address range is displayed under the
Name heading in the format HHHHHxxx. HHHHH displays the first five
hexadecimal digits of the address and xxx represents the three lower
order digits: a range from X'000' to X'FFF' (decimal 0 to 4095). |

Name |
DDNAME of a DASD file. |
Description |
Access method for the indicated file: VSAM,
QSAM, etc. |
Percent of Time |
The percentage of activity measured in routines
that were servicing data management (DASD) requests for the indicated
DDNAME. This includes basic access functions (such as READ and WRITE)
to files. Processing of OPEN and CLOSE functions is not included in
