| General |
Description |
A description of the Until loop. |
| Font Size |
Decrease or increase the font size of the text within the activity. The default font size is 12. |
| Select Condition |
Define the XPath of the condition if the condition is known during design-time. The Until group is executed (iterated) for each XML node in the Message Map that matches the XPath condition. The Select Condition can be of types Static Value or Read From Message. Select the Static Value option to specify the select condition in the Value field. Select the Read From Message option to read the select condition from the Process Specific Messages in the Message Map. This ensures that the business process does not have to be modified for every change. You can build a select condition by clicking the XPath editor icon ( ) appearing at the end of this field. Click this icon to select a condition. |
| Execute Condition |
Enables you to specify the actual condition or the message from where the condition should be picked up for execution.Select one of the following options:
- None: This option is displayed by default. Select this option if you do not want to specify any execute condition.
- Static: Select Static option to specify the actual condition for execution. You can build a condition by clicking the XPath editor icon () appearing at the end of this field.
- Read from Message: Select Read from Message option to read the condition from the Process Specific Messages in the Message Map. This ensures that the business process does not have to be modified for every change. Click to build a condition.
Note:
- Ensure that the Read From Message condition which is taken from the Message Map does not start with a slash.
- If a message contains an XPath expression, then the XPath need not be in single quotes. For example, if the message is /mycondition and it contains an expression as follows: GetEmployeeOutput/GetEmployeeResponse/tuple/old/Employees/City = "London", the XPath will be as follows: GetEmployeeOutput/GetEmployeeResponse/tuple/old/Employees/City = "London".
In an Until construct, the Execute Condition option can be used instead of the Decision construct. You can view a small Decision icon on the left at the bottom of the construct to indicate that the activity includes a condition to be executed.

| Monitoring |
Enable Monitoring |
Enable/disable monitoring for the activity. |
| Monitor Level |
- Activity status: Records activity status, timestamp, user, etc. When you set the monitor level at this parameter, only the activity status is monitored. This helps in getting the updated activity status and to spot errors should the activity abort.
- Activity status, input and output messages: Records the input and output messages of the activity along with its status. When you set the monitor level at this parameter, the activity status and the input and output messages of the message map is monitored. This helps in tracking and spotting any error occuring at this level.
- Store complete activity information if activity aborts: Records activity status and input and output messages information only if the activity process aborts. If the activity is successfully completed, none of the monitoring information is recorded.
|
| Recovery |
Store recovery data (It is a point of recovery from where the process will restart if it fails in middle of execution.) |
Enable/disable recovery data for the activity. When you enable store recovery data at the activity level, the data is recovered only for the current activity. For more information on crash recovery, see Crash Recovery. If the recovery option is not enabled, lost data cannot be recovered when system and other failures occur or when the system is infected by a virus. |
| Recovery option |
The Recovery Option field is visible when crash recovery is enabled for the activity.
- At every iteration: The recovery data point is set at every iteration. This means that at every iteration of the current activity, data is stored for recovery.
- At the end of all iterations: The recovery data point is set at the end of all iterations. This means that dta is stored for recovery only after all the iterations of the current activity are completed.
