Glossary

The following terms are defined in Petals ESB context and must be used in all technical and functional documents.

Terms
Definition Variable names in source code
Process Set of steps assembled to define a processing.
 
Process identifier Identifier associated to a process.
  • processId
Process instance When a process is invoked, a process instance is created representing the process execution.
 
Process instance identifier It is a GUUID (Global Universal Unique Identifier) identifying one and only one process instance.
It can be initialized from outside client when entering in Petals ESB (the outside client is responsible of the identifier uniqueness) and transmitted to application resources to retrieve all steps of a global business process. Inside Petals ESB, this identifier is automatically transmitted step by step.
  • processInstanceId
  • correlationId
  • processExecutionId
  • processRequestId
  • globalMessageId
  • contextUuid
Process step identifier It is a GUUID (Global Universal Unique Identifier) identifying the current step in the current process instance. Inside Petals ESB, this identifier is automatically generated.
  • processStepId
  • flowStepId
Process previous step identifier It is a GUUID (Global Universal Unique Identifier) identifying the previous step of current step in the current process instance. Inside Petals ESB, this identifier is automatically transmitted step by step from the process step id of the previous step.
Used in combination with the process previous step, it permits to rebuild the whole execution of process instance including loop and branch.
  • processPreviousStepId
  • flowPreviousStepId
Component name A component name is an unique name assigned to the component instance at installation time.
  • componentName
  • loggerName
Trace code A code identifying uniquely a trace type in log. For example, all service invocations are logged on the consumer side with the same code.
  • traceCode
Log level All log traces have a level indicating their severity. The logging system can be configured to filter traces to log against their severity (see Logging in Petals). Available severity are:
  • ERROR: An error occurs when the service can not be provided:
    • In a Petals ESB container point of view, an error is something that stops the processing of an internal component. Consequently, the Petals ESB is stopped because it can assume its functions.
    • In a component (BC/SE) point of view, an error is something that stops the processing of the SE or BC, but other components are always running correctly. Consequently, the component could be stopped.
    • In a service (service-unit) point of view, an error is something that stops the processing of a service, each service invocation will fail, but other services deployed on the same component are correctly running. Consequently, the service could be stopped.
  • WARNING: A warning occurs when the service is partially provided and is compensated by a default behavior or it could be hot-fixed without restart or re-installation.
  • INFO: The information level highlights the provided service. Such a trace is logged parsimoniously. For example, service life cycle states are logged with this level.
  • CONFIG: All parameter values are logged with this level.
  • MONIT: This level is used to trace incoming and outgoing service messages to be able to monitor process executions in a business point of view.
  • DEBUG: All traces that can help a problem analysis are logged with this level.
