Deletion Policy

What is your specific question? And my question is, why do you need separate data management policies on different environments?

How Can I extract the UUID of the deployed PMs and then change their policy?

And we need this because I have a web API that triggers a PM that is called multiple times per day, consuming some resources. Want to reduce the impact.

OK, but why not just set the policy to zero days directly?

We want to have different policies between lower and prod environments. This way we can check the PMs on monitoring in lower to see the execution

Makes sense.

You wrote "PM that is called multiple times per day". How high is that number?

Then, did you consider to add a timer node just before the ende node? This way you could keep the model alive for a while for monitoring, but skip that timer on PROD.

To extract the UUIDs, you can create a process report which can list all the process models AND their instances. From process report you will be able to extract Process model metadata. 

AFAIK there is no plugin or smart service that can change the data management policy of any inflights or help you automate this. So changing the policy automatically is impossible. 

May be if you add more details about use case it will enable us to help better like policy of 1 process model are intended to be updated or multiple process models. If its just one then What do you mean with the sentence -

To run this new PM for each new deploy

have a list of exceptions to not be updated when these are deployed.

I dont have the exact number it is evoked +1800 times per day.

The solution that I implemented in the past was:

• a PM for the post deployment feature
• this PM would look into the package that was deployed, get the uuids of the PMs present on the package.
• if the PM were on a list of exception, it would not update
• Else updates the data retention policy.

The plugins used were:

• Application Information Retriever

• Application Plugins

• Process Model Utilities

You can probably achieve this by inspecting the deployment package. You can get it via the deployment API.

Once you have the zip, you can use Zip File Utilities to extract the contents and get the process model uuids.
