HP-UX 11i v3 September 2011 Release Notes, Edition 2

• PAM Kerberos: Enhanced to issue a warning if rc_host_0 is owned by anyone other than
root when a user tries to rlogin into a system; will also issue a warning if the keytable entry
is not found for the host service principal on the client but present at the KDC.
• Security Patch Check: Updated to incorporate defect fixes.
Initial (February 2007) Release Notes, Chapter 9: “Commands and System Calls”
• /etc/skel/.profile shell script: . (current path) in $PATH is deprecated.
• 32-bit pstat System Call (Deprecated): When compiling a 32-bit application that uses the
pstat () system call, the compiler option -D_PSTAT64 must now be specified. This causes
pstat () to use 64-bit fields rather than 32-bit fields. The application still remains a 32-bit
application.
• at , cron, and batch Commands: New features include support for queueing multiple jobs
at the same time, support for queueing of more than 100 jobs, and ability to schedule jobs
up to the njob limit specified for every queue in queuedefs(4).
• core Format Implementation Change: The true version string has replaced the utsname struct
in the CORE_KERNEL segment. A workaround has been provided for applications which
reversed-engineered the core file format and depend on utsname being in it. This new core
file format is now the default format.
• csh Command Line Interpreter: The non-interactive invocation of csh will not source the ~/
.history file by default.
• File Systems Backup and Recovery Commands fbackup, frecover, and ftio: Deprecated;
will be obsolete in a future HP-UX release. You should prepare by migrating to the favorable
replacement pax. Support will be continued for archive retrieval.
• New: gcore Command: creates a core image of each specified process.
• getgroups(), setgroups(): no longer limited by the NGROUPS_MAX.
• getty Command: Enhanced to configure the default setting for special control characters
(erase, kill, etc.) by the user.
• HP-UX Kernel Configuration Commands: Includes several significant changes including revision
of error, warning, and note messages for clarity; new options for kconfig, kcmodule, and
kctune for control of automatic configuration backups; 2 new options for kctune command;
kctune now allows some tunable values to be specified in terms of the percentage of some
system resource; changes have been made to the kernel configuration commands to improve
resiliency and performance; tunable parameter values may now be overridden on the boot
loader command line; and several other changes, including some obsolescences.
• iostat Command: Enhanced to report activity for each active lunpath to the LUNs. Also,
the new option -L has been added, which lists active lunpath statistics.
• Long hostname, uname, and setuname: The limits of these commands can now be expanded
to 255 bytes.
• New: Long Username Support by HFS ff, VxFS 4.1 ff, repquota, quotacheck: Enhanced
to support the username up to 255 bytes.
• lp, lpadmin, lpfence, lpmove, and lpsched Commands: Printers can now be
added/removed/modified without bringing down the lp scheduler; line printer spooler
enhanced to support printer/class names up to 250 characters from the previous limit of 14
characters; support also extended to remote destination names.
