Examples of applications that may take advantage of a large address space are very large databases and large-scale modelling. For the purposes of this section HP-UX releases 9.00 through 9.07 are referred to as 9.x. HP-UX releases 10.01 through 10.20 are referred to as 10.x. Compatibility is supported for well-behaved applications that follow good programming practices. Source Compatibility A 32-bit application that compiled on a 10.x release can be recompiled, without change on 11.00.
Source includes compilers, scripts, and makefiles.
In the financial application example, compiling on HP-UX 11.00 with the 10.20 library is not supported. Compatibility exceptions are described in the Release Notes. Before You Update Get supported 11.00 versions of HP and ISV products. Determine from the vendor which products are binary compatible with 11.00 and which will require upgrades.
