Question

Node level data page in a multi-node environment

How the node level data page is managed in a multi node environment. Will each node have its own copy of the data page, if so then in the event of coming back online after a failure, will it load fresh data from the data source or replicates from one of the available online nodes. How to flush the data pages in all nodes ?

I think it will get the data from the source again. Clear data page button should clear data page from all nodes. if you want it through a code 

1 You can write a java step and use the following method :

pega.getDeclarativePageUtils().deleteAllInstancesOfDeclarativePage("yourdatapagename");

2 Use the function 

@(Pega-RULES:DeclarePages).pzDeleteAllInstancesOfDeclarativePage(tools, Param.PageName).
