PI - deleted message view

HI

I am working in PI 7.1 system. There is no ARCHIVE set for messages.

In SXMB_ADM we have PERSIST_DURATION of DELETION of ASYNC messages are set to 2 days.

Retention period of Async messages is set to 2 days.

(1) So, my query is any ASYNC message will be deleted from XI system in 2+2 =4 days ?

(2) History Entries for Deleted XML Messages is set to 30 days. Can I see the messages older than 4 days in any way
