Discovery Preferences window: z/VM systems page
You can use Discovery Preferences to specify discovery parameters
for z/VM systems.
Fields
- Predefined directory agent servers
- Add
- Allows you to specify a server that is a Service Location Protocol (SLP)
directory agent to assist the management server in discovering z/VM systems.
- Remove
- Deletes the selected directory agent from the list of Predefined
directory agent servers.
- SLP Scope
- Add
- Allows you to define an SLP scope in which to discover z/VM systems. You
can use scopes to group services. There is a standard SLP scope called "default".
- Remove
- Deletes the selected item from the SLP scope list.
- Discovery
- Maximum wait time in seconds:
- Specifies the number of seconds a discovery will wait to find new systems
before timing out.
- Use broadcast
- When this check box is selected, IBM Director issues
a general IP broadcast to discover service agents. If a directory agent is
provided, then this option is ignored. Some sites might not use a general
IP broadcast to discover systems. If your site does not permit general broadcasts,
clear this check box.
- Use multicast
- When this check box is selected, IBM Director issues
an IP multicast in an attempt to discover service agents. If a directory agent
is provided, then this option is ignored. Multicasting can have the advantage
of being able to discover systems across multiple subnets without requiring
specific configuration data for each subnet. Multicast is the preferred discovery
and is used by default. Not all network configurations allow multicast.
- z/VM systems
- Auto-discover period (hours)
- The frequency with which IBM Director Server attempts
to automatically discover other IBM Director systems
for management. This feature can be disabled (the default value) or set to
a period of 1 - 168 hours (7 days).
- Presence Check Period (minutes)
- The frequency with which IBM Director Server checks
the status of each IBM Director system
it can manage. The presence check period determines how quickly the IBM Director Server detects
that a system has gone offline (due to a problem, or being shutdown), or has
come online. The automatic presence check can be disabled, or set to repeat
every 1 - 240 minutes (4 hours). The default setting is 15 minutes.
