Refresh Strategy for a Node Level Data Page
Can you please let me know if there is no refresh strategy defined within a Node level data page and also the DSS - DeclarePages/DefaultIdleTimeSeconds is not available/defined, then will this node level data page be refreshed automatically ?
If yes, how the refresh strategy is defined at run time?

Hi JoyashishS0920,
If you didn't define refresh strategy and if you didn't update value in refresh DSS also, then D_page will never get refresh automatically, once it got loaded under particular node.
After server restart (or) manually if you cleared the D_Page then alone D_page will get refresh again under particular node.

Hi Gunasekaranb,
Thank you for the response. Somehow the data page that I have defined at the node level is getting refreshed automatically even though the refresh strategy is not defined. Also the DSS is also not defined.
Any idea how the data page is getting refreshed automatically ?
Thank you!

Hi @JoyashishS0920
Could you check whether in your code you are using function (or) activity to flush D_Page. If you are not doing this i am not sure then how D_Page is getting refreshed automatically.
I am not sure about this, but this might also be the scenario if we are not having refresh DSS means pega is trying to refresh the D_Page automatically after sometime if D_page is not used.

Hi Joy,
There are 2 ways how a node level data page can be refreshed.
- Clear pages after non-use check box on the data page
- Data page instances for a container reaches a set limit
If "Clear pages" checkbox is checked system checks for Reload if older than fields on the Load Management tab of the data page rule if any of the fields are not set then it checks for the value set for "DeclarePages/DefaultIdleTimeSeconds" either in DSS/prconfig xml.
Since you have said the DSS is not found ,can you please check the value in the corresponding node prconfig xml too and confirm?
By default pega maintains a limit for readonly data pages (defined in datapages/mrucapacity) after which system begins deleting older instances and are loaded back when referenced , but this is highly unlikely to occur in your case unless its a large application.
