Crash recovery

The Pega Platform provides crash recovery for browser and servers. With crash recovery enabled, the Pega Platform saves the structure of the user interface and relevant work metadata to the database on user interface events.

The following matrix details the events that occur if a browser, Pega Platform server, or machine crashes.

Events	Browser crash	Pega Platform server crash
Pega Platform application user interface is redrawn	Yes	Yes
User must re-authenticate	No, if redirected to the same Pega Platform server Yes, if authentication cookie was lost	No, with SSO Yes, without SSO
Data entry loss	No, if redirected to the same Pega Platform server Data not committed is lost if authentication cookie was lost	Data not committed is lost

Additionally, after a crash event, users must:

Reacquire work object locks.
Manually reopen assignments.
