MLPA and dynamic LPA storage is always key 0. Specifying NOPROT turns off DAT protection.
The system does not prevent you from putting non reentrant modules in MLPA or dynamic LPA, but they won't work very well. Jim Mulder -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Mario Bezzi Sent: Monday, December 2, 2024 10:59 AM To: [email protected] Subject: MLPA and NOPROT Reading the manuals I understand that by using the NOPROT option, MLPA modules get loaded into non write protected storage. I was trying this and while I *think* I properly specified it in IEASYSxx, MLPA modules still get loaded in write protected storage. Is there a way to verify that that option is active? Is there a way using IPCS to see the subpool / storage key for MLPA memory? I also played with the SETPROG LPA ADD command and also in this case modules are loaded in write protected memory (SP241 Key 0). Is there a NOPROT like option for dynamic LPA? Finally I was under the impression that one can only put reentrant modules in [any kind of] LPA, but in my experience both MLPA and dynamic LPA accept non reentrant modules. Reason I am doing this is to learn about system integrity exposures to avoid them.
