Chapter 3: Partitions 23
Configuring Partitions
Partition handling of services
The <services> element has four attributes, which are:
To set any one of these attributes, use either the Management Console or
search the Partition's partition.xml file for the <services> node. The valid value
for each attribute is a space-separated list of Partition service names, which
are read left to right. For example, if you wanted to shutdown a Partition
service named ejb_container before a service named transaction_service, you
would set the value of shutdownorder to:
ejb_container transaction_service
Configuring individual services
Each Partition service is configurable within the context of its Partition parent.
The partition.xml file captures information about individual services in the
<service> node, the child node of <services>. In addition, you can use the
<properties> sub-element within <service> to set service-specific properties that
do not come under the auspices of the Partition's runtime executable.
If your services are to be included in the service node lists, you must define
them with a service data block and give them a unique name using the name
attribute. For a full description of the attributes that are configurable for
Partition services, see Chapter 30, “Partition XML reference”.
Gathering Statistics
Each Partition has a Statistics Agent that can be enabled for the short-term
gathering of statistics data. The data is stored onto disk, and is viewable using
the Management Console. Statistics are collected in snapshots performed at a
specified interval, and are cleaned up (removed from disk) at discreet intervals
and after the collection period. This function is called reaping.
You can enable, disable, and configure statistics gathering using the
Management Console or by setting attributes in the <statistics.agent> attribute
of partition.xml. For more information, see Chapter 30, “Partition XML
reference”.
