Node lvel declare page synchronization
SA-679
Summary
In a multi-node environment:
How can we ensure a load activity runs on all the nodes to refresh/load the respective node level “Declare Page” data?
Does refresh/load of data on one node synchronize a node level “Declare Page” data between all the active nodes?
Resolution
If the Declare Page is node based, then each node will have its own copy of the page, modifications performed on one node will not affect the pages on another node.
Can you modify your activity with the pre-condition to check if the page exists to add a wait if the page cannot be found? For example, perhaps add a new step with your pre-condition to see if the page exists, and if it doesn’t, make the step run and just wait for 5 seconds.
On the PDN website, if you type in 'Declare page' you can find many articles about the subject:
