OSB actions in proxy service

In this post we will see about different types of actions to message flows using the Oracle Service Bus Administration Console, such as route, publish, service callout, transport headers, conditional actions, error actions, and message transformation actions.

Actions are the elements of pipeline stages, error handler stages, route nodes, and branch nodes that define how messages are to be defined as they flow through a pipeline

Action	Description
Dynamic Publish	Publish a message to a service identified by an XQuery expression
Publish	Publish a message to a statically specified service.
Publish Table	Publish a message to zero or more statically specified services. Switch-style condition logic is used to determine at run time which services will be used for the publish.
Routing Options	Modify any or all of the following properties in the outbound request: URI, Quality of Service, Mode, Retry parameters, Message Priority.
Service Callout	Configure a synchronous (blocking) callout to an Oracle Service Bus-registered proxy or business service.
Transport Headers	Set the transport header values in messages
Dynamic Routing	Assign a route for a message based on routing information available in an XQuery resource.
Routing	Identify a target service for the message and configure how the message is routed to that service:
Routing Table	Assign a set of routes wrapped in a switch-style condition table. Different routes are selected based upon the results of a single XQuery expression.
For each	Iterate over a sequence of values and execute a block of actions
If...then...	Perform an action or set of actions conditionally, based on the Boolean result of an XQuery expression.
Raise error	Raise an exception with a specified error code (a string) and description.
Reply	Specify that an immediate reply be sent to the invoker.
Resume	Resume message flow after an error is handled by an error handler.
Skip	Specify that at run time, the execution of the current stage is skipped and the processing proceeds to the next stage in the message flow.
Assign	Assign the result of an XQuery expression to a context variable.
Delete	Delete a context variable or a set of nodes specified by an XPath expression.
Insert	Insert the result of an XQuery expression at an identified place relative to nodes selected by an XPath expression.
Java callout	Invoke a Java method from the pipeline.
MFL transform	Convert non-XML to XML or XML to non-XML in the pipeline.
Rename	Rename elements selected by an XPath expression without modifying the contents of the element.
Replace	Replace a node or the contents of a node specified by an XPath expression.
Validate	Validate elements selected by an XPath expression against an XML schema element or a WSDL resource.
Alert	Send an alert notification based on pipeline message context.
Log	Construct a message to be logged.
Report	Enable message reporting for a proxy service.
