How to Create a Detail Process

To create a detail process:

  1. In the SOA Composite Editor, create a second BPEL process service component. For this example, the process is named DetailProcess.
  2. Double-click the DetailProcess BPEL process.
  3. In the Components window, expand Oracle Extensions.
  4. Drag a Receive Signal activity into your BPEL process service component.
  5. Double-click the Receive Signal activity.

    This activity enables the detail process to wait until it receives the signal executed by its master process.

  6. Enter the details shown in Table 16-4:

    Table 16-4 Receive Signal Dialog Fields and Values

    Field Value

    Name

    Enter a name (for this example, WaitForContactFromMasterProcess).

    Label

    Enter a label name (for this example, beginDetailProcess). This label must match the signal activity label you set in the master process in Step 6.

    To

    Select master as the type of process from which to receive the signal.

    Figure 16-6 shows the Receive Signal dialog.

    Figure 16-6 Receive Signal Dialog

    Description of Figure 16-6 follows
    Description of "Figure 16-6 Receive Signal Dialog"
  7. Click OK.
  8. Drag a Signal activity into the designer.
  9. Double-click the Signal activity.

    This activity enables the detail process to signal its associated master process at runtime that processing is complete.

  10. Enter the details described in Table 16-5:

    Table 16-5 Signal Dialog Fields and Values

    Field Value

    Name

    Enter a name (for this example, contactDetailProcess).

    Label

    Enter a label name (for this example, completeDetailProcess). This label must match the receive signal activity label you set in the master process in Step 10.

    To

    Select master as the destination.

    Figure 16-7 shows the Signal dialog.

    Figure 16-7 Signal Dialog

    Description of Figure 16-7 follows

  11. Click OK.

The detail process has now been designed to:

  • Wait until it receives the signal executed by its master process.

  • Signal the master process at runtime that processing is complete.
