HP Java-out-of-box recommendations

In the Java out-of-box Release Notes:
http://www.hp.com/products1/unix/java/java2/outofbox/infolibrary/release_notes_java_oob.html
the recommended value for MAXDSIZ is 2063835136. I'm confused as to why they mention MAXDSIZ and not MAXDSIZ_64BIT, especially since the recommendation is for HPUX 11.x. Is that a realistic setting for MAXDSIZ, which affects 32 bit programs? What about a setting for MAXDSIZ_64BIT?

Yes you are right.

MAXDSIZ is the parameter for the 32 bit programs.
If the programs processes are 64-bit then you should tune the MAXDSIZ_64.

Leon,

I checked my machines running java apps and the setting are as follows:

maxdsiz 2063835136
maxdsiz_64bit 1073741824

Hi,

I think it is because, still most of the applications are all 32 bit

Hi

A lot of this is 32 bit as explained and
maxdsiz_64bit is changed as needed by kmtune usage


If it worries you just increase them both by the same percentage

hi,

on my HP-UX11.11 64-bits, it is set as follows:

kmtune |grep maxdsiz
maxdsiz 0x40000000 - 0X40000000
maxdsiz_64bit 0x80000000 - 0X80000000
