The items of this top level menu item are enabled whenever you are logged on to HCD (i.e. not in stand-alone mode). It will appear to the left of the Utilities menu. The
Operations feature of HCM consists of the following menu items:
- Refresh This command is the primary means
by which the data about the system status is obtained. This information
is volatile i.e. it is not remembered across different HCM sessions, and if
you change the Focus on host. The Refresh menu
consists of the following four submenus:
- Status This refreshes the status information
for all objects in the configuration diagram. This allows you to see the changes you have made to the active
sysplex by showing the updated objects in a different color. The status
bar at the bottom of the screen will display the time at which this command was issued.
- Sysplex This refreshes the current contents
of the Sysplex without updating the status bar refresh timestamp. This command is issued implicitly whenever a configuration is opened,
but the menu option is also provided so that the command can be manually
issued to detect changes to the Sysplex or changes to the availability
of I/O Operations that may have occurred during the session.
- Switch configurations This refreshes the
visualized matrix data for matrices that are being used in the current
diagram. If one or more matrices are not available, messages will appear to tell the user that these matrices cannot be visualized.
Visualization will proceed as if none had been selected as the
Visualized Configuration for the affected switches. This action will automatically issue a "Refresh Sysplex" if one has not yet been issued. The status
bar refresh timestamp is unaffected by this command.
- All This refreshes all of the above information. The status bar refresh timestamp is
updated by this command.
- Sense This command is the only means by
which "Sensed" data from the host is obtained. The menu item consists
of three submenus listed below. Data obtained by the Sense operation appears in the appropriate
columns of the Edit/Locate dialogs. This action will automatically issue a "Refresh Sysplex" if one has not yet been issued.
- Selected This refreshes sensing information
for the object(s) selected in the diagram.
- Visible This refreshes information for all
objects visible in the diagram.
- All This refreshes sensing information for
all objects in the configuration. Since this is likely to be a very long operation, a confirmation dialog will appear. The sensed information is stored in the HCM configuration
file and is non-volatile. Hence, it is retained
across HCM sessions. This information is also available in all List
Boxes in which a Columns button is to be found e.g. the Edit and Locate dialogs.
- Clear Previous Sensing Data This clears the sensed information for all
objects in the configuration.
- Focus on host This dialog allows you to
select the host for which the status information is to be displayed.
- Next focus host This is a shortcut to select (from the list
that would appear in the Focus on host dialog) the next host as the
focus host.
- Command... This starts the I/O Operations command dialog which not only allows you
to issue I/O Operations commands but also allows you to view the results of
them (see Issuing I/O Operations commands).
- Preferences... This dialog allows you to
set various preferences specific only to the Operations feature of
HCM e.g. the format of the system name is selected here.
