AS400 Basic questions

Hello Team,

Request you to answer the below questions

1.) What is Save while act in AS400 and How does it works?
2.) TEST LPAR was unfortunately shutdown and need to restart the LPAR with Restricted state? Does it possible ? i think we should remove the QSTRUPPGM value to *NONE and then restart the system to bring it in Restricted state , but that is not possible when LPAR is in inactive state
3.)what do you mean by Audits in MIMIX
4.) How do we check the Boot Load is TAP01 or not before initiating the IPL : Manual, D for recovery the system from bull backup tape
5.) on what scenarios we use End batch restricted state option in DST?
