Clean data pages from all the running nodes.
Hello,
My application is running on multiple nodes. I want to clean a data page from all the nodes.
Does pega.getDeclarativePageUtils().deleteDeclarativePageInstance(dataPageToFlush, paramPage); cleans data page from all the nodes?
If yes, how does it force other nodes to flush some data page. How does it communicate with other node.
Thanks

Hello Saikat,
@(Pega-RULES:DeclarePages).pzDeleteAllInstancesOfDeclarativePage(tools, DataPageName)
This should delete all instances of data page. You can see the delay in other nodes since it is taken care by System Pulse . Deletion propagates through pulse, so the deletion in other nodes can be visble only after pulse runs once in that node.
I hope this answers your query.
Thank you

Looks like we can remove all the node level data pages from the cluster. But how does it work?
What if I want to remove data pages from all the reqestors with in all nodes in the cluster?

This is right, changes you do in one node will be reflected in other nodes in multinode environment through pulse agent in regards to d_pages.
