checking the status of the cluster resource, change the following parameters. In a non-cluster
environment, these parameter must not be changed. Leave the default settings as is.
Table 16 Parameters in init.conf (to set the retry count and retry interval for checking the status of
cluster resources)
Specifiable values
(default)
DescriptionParameter
0 to 3600
(0)
• In this parameter, specify the maximum retry count
for checking the status of cluster resources. Gener-
ally, specify a value other than 0. When the backup
is of an Exchange database, the time to start the
service depends on the roll forward processing time.
For this reason, when the backup is of an Exchange
database, use the default setting.
• If you specify 0, Application Agent continues to retry
checking until it can check the cluster resource status.
For example, if the cluster resource has terminated
with an error, Application Agent will perform retries
continuously.
• Generally, this parameter should be set to 60.
However, if 60 proves to be too small for a large-
scale system configuration, try setting this parameter
to twice the time it takes to switch the cluster re-
sources between online mode and offline mode in
the actual operating environment.
• When you change the value of this parameter, make
sure that CLU_RETRY_TIME-value x
CLU_RETRY_WAIT-value is sufficiently larger than
the time it takes to complete switching of the cluster
resources between online mode and offline mode.
CLU_RETRY_TIME
0 to 3600
(1)
In this parameter, specify the same number of seconds
as the retry interval for checking the status of cluster
resources.
CLU_RETRY_WAIT
The time it takes to switch cluster resources between online mode and offline mode depends on the
cluster software that is used, the number of disks, the sizes of the disks, the time required to start or
stop a service resource, and other factors. Refer to the table below, and then specify an appropriate
value.
