public class UpdatePersistenceInstanceTask
extends AbstractBaseTask

A Rhino management sub task for updating the settings of a persistence instance.

Ant Parameters
Attribute	Description	Required
name	Name of the persistence instance to create. This name must be unique.	Yes.
type	Type of the persistence instance to create, eg. 'jdbc' or 'cassandra'.	No. Only needs to be specified if changing the persistence instance type.
datasourceclass	Fully-qualified class name the the datasource class to be used by the persistence instance.	No. This parameter is only meaningful if 'type' is 'jdbc'. Only needs to be specified if a different datasource class should be used by the persistence instance than previously specified.
failonerror	Flag to control failure behaviour. If 'true', the sub task will throw a `BuildException` when an error is encountered. If 'false', the sub task will throw a `NonFatalBuildException` instead of a `BuildException` under specific circumstances. See below for conditions (if any) which will cause a `NonFatalBuildException`.	No. Default value is taken from the Rhino management parent task.

Parameters available as nested elements
Element	Description	Required
configproperty	Identifies a configuration property of the datasource class that should be updated. See `ConfigPropertyElement`. Note that the `type` property of `ConfigPropertyElement` is mandatory for this task.	One `ConfigPropertyElement` must be specified per config property.
removeconfigproperty	Identifies an existing configuration property of the datasource class that should be removed. See `UpdatePersistenceInstanceTask.RemoveConfigPropertyElement`.	One `RemoveConfigPropertyElement` must be specified per config property to be removed.

NonFatalBuildException throw conditions

This task will never throw a NonFatalBuildException. It will always fail (throw a BuildException) on errors.

Nested Classes
Modifier and Type	Class	Description
`static class`	`UpdatePersistenceInstanceTask.RemoveConfigPropertyElement`	A nested element that identifies a configuration property to be removed from a persistence instance.
