performance when some of the servers providing resources become unavailable,
StoreFront temporarily bypasses servers that fail to respond. While a server is
being bypassed, StoreFront ignores that server and does not use it to access
resources. Use these parameters to specify the duration of the bypass behavior:
specifies the time in minutes that StoreFront bypasses
an individual server after a failed attempt to contact that server. The default
is 60 minutes.
- allFailedBypassDuration specifies a reduced duration
in minutes that StoreFront uses instead of
bypassDuration if all servers for a particular
Delivery Controller are being bypassed. The default is 0 minutes.
Setting a larger
allFailedBypassDuration reduces the impact of unavailability of a particular
Delivery Controller; however, it has the negative effect that resources from
this Delivery Controller are unavailable to users for the specified duration
after a temporary network outage or server unavailability. Consider the use of
larger allFailedBypassDuration values when many Delivery Controllers have been
configured for a Store, particularly for nonbusiness-critical Delivery
Setting a smaller
allFailedBypassDuration increases the availability of resources served by that
Delivery Controller but increases the possibility of client-side timeouts if
many Delivery Controllers are configured for a store and several of them become
unavailable. It is worth keeping the default 0-minute value when not many farms
are configured and for business-critical Delivery Controllers.
To change the bypass
parameters for a Store
In multiple-server deployments, use only one server at a time to
make changes to the configuration of the server group. Ensure that the Citrix
StoreFront management console is not running on any of the other servers in the
deployment. Once complete,
configuration changes to the server group
so the other servers in the
deployment are updated.
