Known Compatibility Exceptions from HP-UX 11.0 to 11i

Chapter 12 233

NOTE Applications that use undocumented features are not "well behaved."

Tighter Security for NFS Mounts

This change is necessary to improve the security of NFS mounts.

Without this change, when you export a ﬁlesystem using the root=

option of exportfs, NFS-clients on the root= option are allowed to

mount the NFS ﬁle system even when they don't appear on the rw= list

and/or access= list. The new behavior disallows NFS clients from

mounting the ﬁle system unless they appear in either a rw= and/or

access= list.

Memory Size Increase for Process-Private Memory

This change increases the memory size limit for process-private memory.

When the 3rd quadrant private feature is enabled for a process it can

only allocate shared objects in the 4th quadrant. If the 4th quadrant ﬁlls

up, the application may fail, where it would not have failed if the 3rd

quadrant was available for allocation of shared objects.

Removal of MAXTID and Change to MAXPID

The change raises the number of processes or threads to 8 million.

MAXPID, which is undocumented, will be changed. An alternate

mechanism to dynamically determine the value of MAXPID is introduced.

Fortran 90 GETARG Intrinsic Function

This change causes the semantics of the "index" argument to the HP

supplied F90 intrinsic routine GETARG to be compatible with older HP

F77 and other vendor implementations of this routine. Those affected

will have to change and recompile their source code to use the industry

standard indexing scheme.

Software Distributor Bundle Algorithm Change

This change allows you to maintain a depot with multiple versions of a

Software Distributor bundle and automatically get the latest version of

the bundle without specifying a version qualiﬁer. The install process no
