Using dataslots

Table 38 lists the dataslot types that you can assign to a monitoring workstep in the monitoring process. A business event only updates those dataslots assigned to monitoring worksteps.

Table 38. Supported dataslots
Dataslot	Java Type	Comments (if any)
CHARACTER	String	Any string length longer than the maximum length specified for the process template, is truncated.
INTEGER	Double, BigDecimal
INT64	Long
LOGICAL	Boolean
DATETIME-TZ	Long	Date must be specified in milliseconds.
LIST	List
Map	Map

Note: Dataslots of the type Object and Business Object are not supported for a monitoring process.

The following business events can modify the value of the dataslots in the monitoring process instance.

UPDATE_DATASLOT: This event can update the value of any user-defined dataslot (of the type listed in Table 38) in the monitoring process, including those dataslots not added to the monitoring workstep. This event identifies the process instance using the EIID value, before updating the dataslot values. If the value of the dataslot passed on by the event is invalid, then the dataslot update fails.

COMPLETE_WORKSTEP: This event can only update the values of the dataslots (of the type listed in Table 38) added to the monitoring workstep. This event triggers the completion of the monitoring workstep, only after updating the dataslot values. If the value of the dataslot passed on by the event is invalid, then the dataslot update fails.

Note: The UPDATE_DATASLOT and COMPLETE_WORKSTEP events cannot update the EIID value.

To add a dataslot to a monitoring workstep:

1. From the Properties view of the workstep (external activity or adapter), click the Dataslots tab.

2. Click Add to open the Select Dataslots dialog box, which lists all the user-defined dataslots in the monitoring process.

Note: You must add only editable dataslots to a monitoring workstep.

3. Select the dataslot to be added, then click OK to add the dataslot to the table provided in the Dataslots tab.
