How much Program Data in 32-bit API with ACE 99/11?

I we use ACE(additional Core Enhancements) 99/11, how mcuh Program data size is avalable.

According Online release notes, It seems that 2G for default.
32-bit API of Program Text is 1G,
Program Data is 2G, right?

Is my undertanding correct?
Thanks for any help...

Text is 1Gb, Data is just under 2Gb (~1.9Gb), but there are ways to increase the data size up to 2.75Gb or even 3.6Gb if really needed, but on HP-UX 11 there really is no limit to data size.

Stefan, for 32bit 11, there is a limit. Even 64bit has a limit. Ok, it's 1TB, so that should be enough currently!

As you say, without ACE, it's 1.9 using exec_magic and 2.9 with ACE. Takesui seems to keep asking this question a couple of times a day.

Andy,

My question is:
Without -N option or Memory Windows,
With ACE 99/11,
32-bit API of Program Text is 1G,
Program Data is 2G,

It is definitly to use more 1G Program Data than without ACE, right?

People who wants to use Program Data for 32-bits API, definitly, it is good thing to install ACE 99/11.
Does my underderding correct?
Any comments highly would be appreciated.

I dont believe you have to install the ACE bundle just to increase the data limit from 1.9Gb to 2.75Gb. We just intalled the memory windows patch (PHCO_16795 - probably superceeded by another patch by now), and relinked Oracle with the EXEC_MAGIC option. You may need an oracle patch also.

How about 32-bit API which was compiled without ACE 11/99 on HP-UX 11.0 and run it with ACE 11/99 on HP-UX 11.0.

Program Data of 32-bit API is limilted to 1 GB
Or 2GB?

Hi, Stefan.
PHCO_16795 patch seems to me that
it is similar to with ACE 11/99 on HP-UX 11.0.

If our machine is installed by PHCO_16795 patch.
Does Program Data of 32-bit API is limilted to 2GB, right?

Our case is share-memory area is no problem,
Problem is Program Data area.
