Increase the WebSphere Application Server session timeout value to avoid losing unsaved data.
Consider extending the expiration value of the WebSphere Application Server session security Lightweight Third-Party Authentication (LTPA) tokens from the default value of two hours to a longer time. When the LTPA token for a session expires, a user logged into Mashup Center over that session will be forced to log in again, which can result in the loss of unsaved data.
To increase the LTPA timeout value, open the WebSphere Administration Console and select Security
-> Global Security
. Under Authentication
. Under LTPA timeout
, enter the number of minutes.
