Chapter 4168
Serviceguard Manager in the EMS tab’s Browse button
(“Available EMS resources”), or obtain it from the
documentation supplied with the resource monitor.
A maximum of 60 resources may be defined per cluster.
Note also the limit on Resource Up Values described
below.
Maximum length of the resource name string is 1024
characters.
Resource polling interval
The frequency of monitoring a configured package
resource. In the ASCII package configuration file, this
parameter is called RESOURCE_POLLING_INTERVAL.
Default is 60 seconds. The minimum value is 1. The
maximum value has no functional limit.
The Resource Polling Interval appears on the list
provided in Serviceguard Manger’s package
configuration screen, EMS Resource tab’s Browse
button (“Description of selected EMS resource”), or you
can obtain it from the documentation supplied with the
resource monitor.
Resource start
An attribute of a resource that determines whether it
should start up before or after the package starts. In
the ASCII package configuration file, this parameter is
called RESOURCE_START.
Default setting is AUTOMATIC, which means that the
resource starts at the time the node joins the cluster.
The other possible setting is DEFERRED, which means
that the package services will start up before the
resource starts. If a resource is configured with
DEFERRED startup, the name of the resource has to be
added to the control script’s DEFERRED_RESOURCE_NAME
parameter. (If you use Serviceguard Manger’s guided
mode to create the control script automatically, it will
be entered for you.)
