I understand now however the second address space is a started task

So I don't have axlist,tklist,lxlist available

I guess thinking about it the design was a good
Idea as we shouldn't be "hacking" into system 
Address spaces

Re: XMEM and Swap ability

2016-05-17 Thread Rob Scott 
If you are in control of both address spaces (ie the second ASID is not 
"foreign"), there are all sorts of non-common memory sharing options available 
to you, including (but not limited to) :

(1) ASID1 starting ASID2 using ASCRE - you can get an official cross-memory 
bind and then use ALETs to access data in ASID2 from ASID1
(2) Use shared memory objects
(3) Use PC-ss owned by either/both ASIDs to add items to queues in the other 
ASID
(4) SCOPE=ALL dataspaces
(5) IARVSERV

Why would I ignore a bad design?

 If you are asking for advice, be humble enough to accept that others already
went down the path and are aware of the dangers.

Explain why you need access to the other address space. What is your business
case?

Should you use the mailblocks package and expect a response from me,
you should preauthorize the dissensoftware.com domain.

I very rarely bother responding to challenge/response systems,
especially those from irresponsible companies.

Space #1 should schedule an SRB to Space #2. That SRB can PC back to a 
routine in the private area of Space #1. That routine can use AR mode to 
copy anything it wants in either direction without fear of abend caused 
by swap out of either space.

XMEM and Swap ability

2016-05-15 Thread michealbutz 
Hi,

 

Transferring data between 2 address spaces weather its MVCP/MVCS or AR mode
there is always the possibility of a S0C4. 

 

What the best way of making sure the target Address Space is Swapped in.
Doing XMEM post to  the target address space  to do a SYSEVENT ?  

 

Thanks
