|| 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 execution identifier* Process instance identifier
* Correlation identifier
* Global message identifier
* Context UUID | 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 and transmited to application resources to retrieve all steps of a global business process. Inside Petals ESB, this identifier is automatically transmitted step by step.\\ | * correlationId
* processExecutionId
* processRequestId
* globalMessageId
* contextUuid |
| * Process loop identifier | This identifier is used to identify the loop iteration in which steps are executed. Without the process execution identifier, this identifier has no real sens.\\ | * processLoopId |
| * Process branch identifier | This identifier is used to identify the parallel branch in which steps are executed. Without the process execution identifier, this identifier has no real sens. | * branchId |
| * Component name / logger name | Key identifier associated to the component instance to identify uniquely a component instance inside a Petals node.\\ | * 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 |
