HP-UX 11i v3 March 2012 Release Notes

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 batchCommands: 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 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.

is chosen at boot time; and to the manner in which the system automatically maintains a
backup kernel configuration.
• iostat : Enhanced to report activity for each active lunpath to the LUNs. Also, the new
option -L has been added, which lists active lunpath statistics.
