maxswapchunks - user defined kernel varable?

[dictum9]

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

[A. Clay Stephenson]

It's been phased out at 11.23.

[Patrick Wallek]

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

[Sp4admin]

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

sp,

[dictum9]

that's the answer, it no longer exists.

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

[Patrick Wallek]

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
