Service Grid Deployment Descriptor Elements

The Service Grid Deployment Descriptor dtd can be found here

Element Description
Association Associations provide the capability to specify directed service associations and enforce them in runtime.
Associations Contains one or more Association elements.
Attribute Specifies name and value pairs that are used to populate a Properties object.
ClassName Specifies the name of a class.
Cluster Contains one or more Machine elements.
Codebase Specifies where service classes and resources can be (down)loaded from.
Comment An optional element. If the Comment element is supplied, its value should provide an accurate comment for the Services role.
Component Contains multiple Parameter elements which document Configuration Entries for use with net.jini.config.Configuration. There can be zero or more Parameter elements in the Configuration element.
Configuration Specifies a list of Component elements.
DeployDate Specifies a Month, DayOfMonth, DayOfWeek, Hour, and Minute. If a DeployDate is not provided, the Deployment Descriptor, when deployed, is deployed immediately.
DeploymentSchedule Allows a deployer to specify when an application will be deployed and how long it will remain deployed.
Download Provides a way to declare a downloadable unit of software from a source location, to a targeted installation root directory. The installation root directory is a relative directory, and will be appended to the provision root directory determined by a Cybernode. If the characters / or }} are used in the installation root, they will converted to platform specific file-separator characters. If the {{Unarchive attribute is declared as yes, the downloaded software will be extracted to the InstallRoot location.
Duration Declares how long a Deployment Descriptor is deployed. If not provided, the duration is indefinite.
ExecutionTarget Specifies a utility that is started in order to configure a downloadedSoftwareLoad. If the ExecutionTarget ends with .jar, the target will be invoked using the Java Virtual Machine as an executable JAR file, otherwise the ExecutionTarget is started as a separate operating system process.
FaultDetectionHandler An optional element (as far as being declaritively optional – if not specified, a default handler will be used). The FaultDetectionHandler must periodically test to make sure the service is reachable. Can implement custom fault detection alogorithms and protocols to determine service reachability.
Formatter Defines a java.util.logging.Formatter class to use with a Handler.
Group Documents a group that the service uses for discovery.
Groups Provides a list of Group elements. There must be at least one Group element. 
<Groups>
    <Group>myGroup</Group>
</Groups>
Handler Identifies a logger name and a logging level. The Handler element also allows you to add a Handler to the Logger.
ImplementationClass Specifies the name of the implementation class for the service. The value should be suitable for use with Class.forName().
Include Includes another Deployment Descriptor.
Interface Specifies a string value that identifies the interface class or classes the Service element can be discovered with through the network. The value should be suitable for use with Class.forName().
Interfaces Contains one or more instances of an Interface element, and an optional Resources element, which provides information on where to load the Interface classes from.
Interval Specifies the amount of time to wait between repetitions.
JAR Declares a JAR that is used to load a class. If the Location attribute is specified, it overrides the value declared in the Resources element. The value is machine-dependant, and must point to the exact location of the JAR in the file system. If a JAR cannot be accessed at the specified Location, an exception will be thrown and the Deployment Descriptor will fail to load.
Location Used by the Download element to declare the location of a source to download.
Locator A Jini Lookup locator URL, in the format of jini://hostname[:port], which provides Unicast information the service optionally uses for discovery.
Locators Contains one or more instaces of a Locator element. 
<Locators>
	<Locator>jini://host1</Locator>
	<Locator>jini://host2</Locator>
</Locators>
Logger Identifies a logger name and a logging level, as well as providing the capability to add a Handler to the Logger.
Logging Provides information for Loggers.
Machine A machine to provision a ServiceBean to. Needs to be either the hostname or the IP Address. The provisioning runtime still enforces QoS provision requirements.
Maintain Documents the number of instances of this ServiceBean that should be available through the network.
MaxPerMachine Documents the number of instances of this ServiceBean that should be running on any specific virtual machine that supports the requirements of the ServiceBean.
monitor A declarative GaugeWatch.
Organization An optional element which allows a deployer to indicate an organization (representative owner) of the ServiceBean.
Parameter Specifies name and value pairs, identifying an operational parameter for the ServiceBean.
Parameters Specifies a list of Parameter elements, that are used to describe operational parameters used by the ServiceBean. There can be zero or more Parameter elements in the Parameters element.
PolicyHandler Provides an alternative to specifying the policy handler that is used to enforce the SLA.
PostInstall A mechanism that declares a post-install utility, that can be downloaded and executed to configure a downloaded SoftwareLoad.
Properties An optional element that specifies a list of Property elements that describe operational properties used by the FaultDetectionHandler. There can be zero or more Property elements in the Properties element.
Property Specifies name and value pairs, identifying an operational property for the FaultDetectionHandler.
Repeats A way to declare how many times a deployment should be repeated, and what the Interval is between repetitions. If the Interval element is not provided, the default repeat interval is used.
Resources Declares one or more resources required to load a software component. It also provides context as to whether MessageDigests should be computed for enclosed JAR elements. If MessageDigests are computed for JAR elements, the resulting protocol is httpmd://, not http:// for each JAR. Make sure the java.protocol.handler.pkgs property is set to net.jini.url.
If the Location attribute is specified (if it is not used, the Codebase URL is used to compute the MessageDigests), it is used to access all JAR files on the local machine. The Location value is machine-dependant, and must point to the exact directory location for the JARs in the file system. If a JAR cannot be accessed at the specified Location, an exception is thrown and the Deployment Descriptor fails to load.
SLA Provides the means to specify low and high limits, an acceptable range, for a SLA with a given ID. Additionally, the SLA provides a mechanism to configure a SLAPolicyHandler, which can be used to process policies specific to SLAs as they occur, taking specific actions appropriate for the ServiceBean.
Service A service that is included in the Deployment Descriptor, but is not allocated to available compute resource instances.
ServiceBean A dynamic service that supports the Service Bean model. The ServiceBean element is unique in this manner, because it is allocated to available compute resources based on the capability to match the ServiceBean operational and platform requirements to available compute resource capabilities.
ServiceLevelAgreements Contains information specific to the Quality of Service mechanisms involved in order for a ServiceBean to provide SLA management, specific mechanisms of the compute resource, and service-defined SLA mechanisms.
ServiceProvisionConfig Optionally declares configuration elements used during service provisioning.
SharedComponent A construct that allows a class to be dynamically installed into the GSC's ComponentLoader.
SoftwareLoad Defines an installable software element with a post-install helper to configure the downloaded software. The SoftwareLoad element additionally provides a RemoveOnDestroy attribute, which causes the SoftwareLoad to be removed from the compute resource when the ServiceBean has been terminated. If the RemoveOnDestroy is declared as no, then the SoftwareLoad will remain on the compute resource after the ServiceBean has been terminated. Additionally, the compute resource's PlatformCapability collection will be updated to reflect the addition of the SoftwareLoad.
SystemComponent Defines a system component class (as an attribute) and zero or more name and value mappings for a specific PlatformCapability class. A SoftwareLoad can be provided as well, indicating that the SystemComponent, if not found, might be dynamically provisioned to a Cybernode that supports dynamic provisioning.
SystemRequirements Specifies which system components and measures must be present on a compute resource for a ServiceBean to be provisioned.
Utilization Provides the means to specify low and high limits, an acceptable range, for a specific quantititaive capability on a compute resource. The Utilization values are used during the allocation or provisioning of ServiceBean instances to compute resources appropriate for the ServiceBean.
gs-deployment The outermost tag, which defines at least one deployment.

mirror-service Enables the Mirror Service in a cluster, using the <enabled> tag, and a Mirror Service URL.
multicast The multicast configuration tag in the replication schema.
notify-recovery When this element is true, it tries to recover the notify template from one of the replication group members. If it doesn't succeed, it then tries to recover notify templates from the other cluster members.
policy-type – replication group Optional values: Full Replication – all Entries in the group's spaces are replicated. Partial Replication – Entries are only replicated if their class implements the Ireplicatable interface.

response-timeout Maximum expected response time in milliseconds to get acknowledged from the target space.
source-member Defines the member of the group from which data will be recovered from.
sync-on-commit Set to true if you use transactions and you want the commit operation to be blocked until all members of the replication group receive the changes made by the transaction.
sync-on-commit-timeout Relevant if <sync-on-commit> is true. This is the period of time (in milliseconds) that the source space waits to get acknowledged from the target space in order to commit the replicated transaction data.
