HP-UX 11i Version 2 March 2004 Release Notes

What’s New at a Glance

What’s New in the Initial HP-UX 11i v2 Release?

Chapter 3

• Strong Random Number Generator: New feature provides a secure, non-reproducible

source of binary sequences for applications that generate encryption keys and other

cryptographic quantities.

Chapter 8: “Commands and System Calls”

•The envd Environment Daemon: Now supported.

•The groupadd, groupdel, groupmod, useradd, userdel, usermod commands: In

trusted mode, the commands now write audit records into the audit subsystem’s

audit trail. New option added to set or unset useradd behavior of changing

ownership of an existing home directory.

•The psrset Command: Enhanced with new options to manage the RTE processor

set.

•The setboot Command: Support for setting the HA Alternate boot path now added.

SpeedyBoot option for next reboot now available.

• I/O Commands:

—The insf, lssf, and mksf Commands: Now support IHV drivers, provided the

IHV provides a shared library.

—The ioscan command: New options added to allow display of the date and time

at which the system hardware was last scanned and to allow display of the EFI

device paths for certain devices.

•The mmap() Function: Now possible to perform mappings between a process's

address space and I/O device registers or memory.

•The pstat_getfile() Interface: Obsolete. The interface pstat_getfile2() should

be used in its place.

• Transition Links Commands: Deprecated. The tlinstall, tllist, and tlremove

commands will become obsolete in post-HP-UX 11i v2 releases.

• Usage of Capacity-related ioctls DIOC_CAPACITY, DIOC_DESCRIBE, and

SIOC_CAPACITY: Applications that use the DIOC_CAPACITY or DIOC_DESCRIBE ioctl

calls should be rebuilt because capacity_type and disk_describe_type now better

represent the size of newer, larger devices. Applications that use the SIOC_CAPACITY

ioctl for devices that may become large at some point should now use the new

SIOC_STORAGE_CAPACITY ioctl.

•Usage of ustat(), statfs(), and statvfs(): When old binaries that still use

ustat(), the various forms of statfs(), and the various forms of the 32-bit flavor of

statvfs(), are exposed to a truly large file system, these calls will return an

EOVERFLOW error that the binaries have never seen before, resulting in

misinterpretations.

Chapter 9: “Libraries and Programming”

• 400K File Descriptors: The maximum supported number of file descriptors per

process raised from 60000 (60K) to 400,000 (400K). Precautions apply to this new

functionality.
