Large Heap Size with 32-bit Java

HP-UX 11.11 (PA-RISC)

• Because of segmentation in the HP-UX virtual address space,

when the Java heap is larger than 3000MB, either new space (-

Xmn) or old space (-mx minus -Xmn) must be approximately

850MB or less (applicable to 11.11 only).

HP-UX 11.00 or greater

• You do not need to directly invoke any of the q3p or q4p

programs. Just invoke 'java' as usual, and the appropriate

program will be run for you.
