Flush Parameterized Data Page on all Nodes from Activity/Data Transform
Hi Pega Support Team,
How can we flush the Node level data page on all configured nodes from an Activity or Data Transform?
I know in 7.3, we have an API for getting all nodes configured and running (pega.getSystemOperationsProvider().getClusterManagementAPI().getNodesInCluster()) but is there any other API to clear all the data pages from all node.
Thanks in advance,
Somit

Hi Somit
I have used the below function in Activity to flush individual data pages:
@(Pega-RULES:DeclarePages).pzDeleteAllInstancesOfDeclarativePage(tools,"<Data Page Name>")
This is the Pega OOTB function, but you have to pass the Data page name to it.

I believe this won't flush pages on all nodes. Please correct me if i am wrong.

Hi Somit,
You can also use pzFlushDataPage activity to flush data page.

Thanks for reply Vinay,
But my question is how you will flush the data on all nodes programmatic. pzFlushDataPage or Page-Remove will just flush the data from one node.

I read this article already but was looking for a well documented article on it. We are on 7.1.8 and i think this feature is not available/working to clear data pages on all nodes simultaneously. I will do small POC on 7.3 system and update.

Thanks Vinay,
This article will help me to understand the behavior better. I believe this is true for the parameterized data pages as well.

Thanks for sharing the info Vinay,
I went through the article in detail and understood this is only for the non-parameterized data pages. Still i am looking for an answer if we can flush the Parameterized data pages on all nodes through any function like ExpireDeclarativePage, FlushDeclarativePage, deleteAllInstancesOfDeclarativePage etc .
