maxswapchunks - user defined kernel varable?

dictum9 — Fri, 01 Sep 2006 15:13:07 GMT

Why am I getting the following, I thought it was a standard variable?
I had no luck finding that variable in sam either.

# /usr/sbin/kctune -h -B maxswapchunks=16384
ERROR: The tunable 'maxswapchunks' is not known. (If you are trying
to create a user-defined tunable, specify the -u flag.)

if you look in sam --> kernel configuration --> configurable parameters --> maxswapchunks

It's been phased out at 11.23.

If you are on HP-UX 11iv2 (11.23) then maxswapchunks no longer exists.

With HP-UX 11.23 maxswapchucks is nologer a tunable parameter.

that's the answer, it no longer exists.

now what about semmap? Does that variable no longer exists either in 11.23?

Nope, that one does not exist in 11.23 either.

Hi /etc,

more information about 11.23 kernel tunning:

â ¢ Several commands are obsolete in HP-UX 11i v2:
â configâ configure and build an HP-UX system.
â kmadminâ kernel module administration.
â kminstallâ add, delete, update the installation of a kernel module.
â kmmodregâ register or unregister loadable kernel modules with the running kernel.
â kmsystemâ set, query planned configuration attributes of kernel modules.
â kmupdateâ update default kernel, or update specified kernel modules.
â Deprecated Commands
â kmtuneâ this now calls kctune.
â kmpathâ this now calls kcpath.
â mk_kernelâ this is now a script that calls kconfig.

â ¢ Several new commands are added in HP-UX 11i v2:
â kconfigâ used for managing kernel configurations.
â kctuneâ used for managing tunable kernel tunables (tunables).
â kcmoduleâ used for managing the states of kernel modules
â kclogâ used for viewing the contents of the kernel configuration log.
â kcpathâ used by scripts to determine the path of the running kernel.

â ¢ Several tunables have been obsoleted and new ones added
â Obsolete Tunables
â shmem
â sema
â mesg
â maxusers

â New Tunables
â fs_symlinks (5) - Maximum number of symbolic links used to resolve a path name
â aio_proc_threads (5) - Maximum number of process threads allowed in AIO pool
â aio_monitor_run_sec (5) - Frequency of AIO thread pool monitor execution (in seconds)
â aio_proc_thread_pct (5) - Percentage of all process threads allowed in AIO pool
â aio_req_per_thread (5) - Desirable ratio between number of pending AIO requests and servicing
threads

â Tunables Made Dynamic
â nfile (5) - maximum number of open files (system-wide)
â nflocks (5) - maximum number of file locks
â dbc_min_pct (5) - minimum percentage of memory used for caching file I/O data and metadata
â dbc_max_pct (5) - maximum percentage of memory used for caching file I/O data and metadata
â aio_max_ops (5) - maximum number of POSIX async I/O operations that can be queued at any
time
â aio_listio_max (5) - the maximum number of POSIX asynchronous I/O operations that can be
specified in a listio() call
â aio_prio_delta_max (5) - greatest delta (slowdown factor) allowed in POSIX async IO request
priorities
