TRACE Command
The TRACE command prints a snap dump in trace fashion after certain
operations within DYNUTIL. The DATA operand produces large quantities of
output and should be used only at the request of CA Technical Support
personnel.
This command has the following format:
TRACE
{ CATLIO } [DATA]
{ DISKIO }
{ TAPEIO }
{ VTOCIO }
{ ALL }
{ OFF }
CATLIO, DISKIO, TAPEIO, VTOCIO
Defines the specific event to be traced: Catalog input/output, disk
input/output, tape input/output, or VTOC input/output, respectively. These
operands are mutually exclusive.
ALL
OFF
DATA

Provides SNAP dumps of the data buffers for each I/O.
Reporting on Disk Files
CA Dynam supplies the following standard, precompiled reports to assist you
in the management of disk files:
• Disk Space Usage Analysis—SPACEUSE
• Volume Table Of Contents—VTOCS
The SPACEUSE report informs you of the relative efficiency with which disk
space is being used. It helps optimize space utilization and system
performance by identifying badly blocked or allocated files. Data is retrieved
from system VTOCs in VTOC sequence by volume.
