vRealize Orchestrator Workflow basics – Part 2

So let’s continue where we left it, we are going to analyze the “Schema” tab in depth.

First, we have a left pane with different items that we can drag & drop into the can space (right pane).

vRO_22

We can drag & drop various kind of items, like, scriptable tasks, actions and other Workflows.

vRO_23

This is the design of our Workflow, we have inserted scriptable tasks, a decision and a counter decrease.

vRO_24

We start checking what we’re doing on first item (Scriptable task). As you can see is very useful to put a description on every item, we are going to take the input “number” and copy the value to the attribute “numberTemp”, in that way we leave intact the input and we will work with “numberTemp”.

vRO_25

Select the input for the scriptable task.

vRO_26

The output.

vRO_27

No exception configured.

vRO_28

At “Visual Binding”, we can see really fast the relationship between, what gets in and what gets out. As you can imagine you cannot bind variables of different types. (We will see on future posts that here we can create inputs, outputs and attributes just with drag & drop)

vRO_29

Finally, we see the scripting code, this is an easy one (JavaScript).

vRO_30

Continuing with the next item, we will make a decision to take one way or another. As we are making a countdown, we want to know when we arrive to zero.

vRO_31

We setup the comparison, we take the “numberTemp” and check if equals zero.

vRO_32

If does not equal zero we will jump in to the way of “not true”, and go to next item “Log Value”.

Obviously this one will log the actual value of “numberTemp”.

vRO_33

“numberTemp” is an input and the output.

vRO_34

Again the visual binding.

vRO_35

Here you have how to log things at the Workflow execution log (There is also another option Server.log, they are different, we will explain more on that on future posts).

vRO_36

So let’s countdown with the help of a Decrease counter item.

vRO_37

We bind the counter to “numberTemp”, input and output.

vRO_38

vRO_39

This is the auto-generated code for Decrease counter item.

vRO_40

Then the workflow will return to the decision, this loop will occur until “numberTemp” equals zero.

vRO_41

When it equals zero we will take the way of “is true”.

Finally we do last step, add five to input number and log.

vRO_42

We need both inputs “number” and “numberTemp”.

vRO_43

As output “numberOut”, this one can be used in another Workflow if we concatenate Workflow executions.

vRO_44

As usual the bindings.

vRO_45

Scripting code.

vRO_46

So, let’s see this entire staff doing the job.

vRO_47

We want to make the countdown from 20, and then add 5.

vRO_48

After successful execution.

vRO_49

If we check the log.

vRO_50

That seems job DONE.

Finally, I want to remark that we can Schedule or debug the workflow not only start it.

vRO_51

vRO_52

I hope this post is a good point to start understanding the philosophy of vRO.

I will come back soon with a real life Workflow.

Thanks for sharing 🙂
