Property

UI Field Name

Description

Specifications

Required

condition

n/a

Dependency condition between the source and target tasks of this dependency (connector).

Valid values:

  • Success
  • Failure
  • Success/Failure
  • Exit Code; Format: Numeric. Use commas to list a series of exit codes; use hyphens to specify a range. Example: 1,5, 22-30
  • Step Condition; Format: step:procedure:program:condition codes. Example: *:*:*:JCLERR
  • Variable


Default is Success.
 
For example:

 <condition>Success</condition>
   <condition>Failure</condition>
   <condition>Success/Failure</condition>
   <condition>1,5,22-30</condition>
   <condition>*:*:*:JCLERR</condition>
   <condition>S1:PROC1:PGM1:U016</condition>
   <condition type="Exit Code">1,5,22-30</condition>
   <condition type="Step Condition">*:*:*:JCLERR</condition>
   <condition type="Step Condition">*:*:*:S0C4</condition>
   <condition type="Step Condition">S1:PROC1:PGM1:U016</condition>
   <variableCondition>
           <firstValue>${_varToLowerCase('variableName')}</firstValue>
           <operator>=</operator>
           <secondValue>${var2}</secondValue>
   </variableCondition>


 
Step Condition is valid for z/OS tasks only.
 
Success/Failure and Failure are not valid for Workflow, Timer, and Manual tasks.
 

Note

The type attribute (type=) is optional for Exit Code and Step Condition. Based on the format of the condition, in most cases it is easily determined if the condition is Exit Code and Step Condition. If the condition cannot be determined, the type attribute can be checked.

N

points

n/a

If straightEdge is false; x and y coordinates of the Edge angles.

For example:
 

<points>
	<point x="280" y="300" />
</points>

N

sourceId

n/a

Y

straightEdge
