SCREEN Command
SCREEN Command
Use the SCREEN command to replay a previous logged ViewSys session. If different
screens are selected for display during the logging of the ViewSys session, on
playback only the default ViewSys screen will be displayed. This option is primarily
intended for QA purposes.
LOG
indicates that the VIEWSYS data will be logged to a disk file named DISPFILE in
the current volume/subvolume. The DISPFILE can be used to replay the data. If the file
already exists, it is overwritten.
REPLAY
indicates that VIEWSYS will be running on replaying data from a disk file named
DISPFILE in the current volume/subvolume. This parameter causes ViewSys to
replay the all processors screen (ViewSys default screen) displaying the bar graph
percentages of each metric for each configured CPU on the node.
OFF
indicates that the VIEWSYS data will not be logged to a file called DISPFILE and
VIEWSYS will not be running on replaying data. OFF is the default setting.
Example

SWITCHBACK Command
Use the SWITCHBACK command to indicate whether the backup (or secondary)
processor should retain responsibility once the primary processor has recovered from
a failure.
ON
indicates that should the backup process take over due to the failure of the
primary's processor, once the original primary processor is again available, the
original backup will return the responsibility to the original primary process.
SCREEN { LOG | REPLAY | OFF }
Note. The EOF for the CSVFILE increases during every ViewSys sample interval. Disk space
consideration is a must when using this parameter. This option is primarily intended for QA
purposes.
