maxusers(5) -- OBSOLETED
|
|
This tunable has been obsoleted and removed in the HP-UX 11i Version 2 release. Please do not make any changes to this tunable as they will have no effect on the kernel. Prior to the HP-UX 11i Version 2 release, the maxusers tunable was used to calculate the default values of nclist, nfile, and ninode, all of which control kernel data structures that determine the system resource allocation. As of... |

maxvgs(5) -- maximum number of LVM Volume Groups that can be created/activated on the system
|
|
Maximum number of LVM Volume Groups which may be created or activated on the system. This value also limits the range of Volume Group numbers allowed. A maxvgs value of 10, for example, allows 10 Volume Groups to be created on the system, and the Volume Group number of each Volume Group is a unique value in the range of 0 to 9. Who Is Expected to Change This Tunable? Anyone. |

max_acct_file_size(5) -- defines the maximum accounting file size
|
|
max_acct_file_size is a dynamic tunable that limits the maximum accounting file size. See acct(2) and acct(4). If max_acct_file_size was set to a value that is not a multiple of the accounting record size, the tunable will be rounded up to the next full record silently unless the maximum limit is reached. In this case, the tunable will be rounded down to the nearest full record silently. The only ... |
|
max_async_ports(5) -- maximum number of asynchronous disk ports that can be open at any time
|
|
The asynchronous disk driver provides an interface to execute highperformance I/O to the raw disk. Instead of reading or writing directly to the raw disk, a process writes requests to the asynchronous driver which then makes appropriate calls to the disk driver. Every process that opens the asynchronous disk driver is assigned a port. The driver uses the port to keep track of I/O and other interna... |

max_mem_window(5) -- maximum number of group-private 32-bit shared memory configurable by users
|
|
32-bit processes usually share the global quadrants 3 and 4 for such things as I/O mappings, shared libraries, shared mapped files, etc. However, you may wish to use quadrant 3 in a more limited sharing fashion with only a select group of processes. Memory windows allow this functionality. If this tunable is set to 0, 32-bit programs always use the global Q3 and Q4 for shared memory. If this tunab... |
|
max_thread_proc(5) -- defines the maximum number of concurrent threads allowed per process.
|
|
max_thread_proc is a dynamic tunable that limits the maximum number of threads allowed per process on the system. When tuning max_thread_proc, the maximum number of threads allowed per process will be the new value of max_thread_proc. No process will be able to create new threads such that the total count of its threads exceeds max_thread_proc. Who is Expected to Change This Tunable? System admini... |
|
mesg(5) -- enable or disable System V IPC messages at boot time
|
|
The mesg tunable is obsolete. The System V IPC message subsystem is always enabled. |
|
mfconv(5) -- Mainframe code set conversion
|
|
Provide code set conversion between Mainframe and HP-UX Japanese code sets. These code conversions are available by iconv(1) command and iconv(3C) function. Following Mainframe code sets are supported for code conversions: |
|
mknod(5) -- header file of macros for handling device numbers
|
|
The header file defines macros to create and interpret device identification numbers for use with the mknod() system call (see mknod(2)). The use of these macros is architecture-dependent. See the System Administration Manual for your system for information on how to select major and minor device numbers. mknod.h contains the macro dev_t makedev(int major, int minor) which packs the ... |

mknod.h(5) -- header file of macros for handling device numbers
|
|
The header file defines macros to create and interpret device identification numbers for use with the mknod() system call (see mknod(2)). The use of these macros is architecture-dependent. See the System Administration Manual for your system for information on how to select major and minor device numbers. mknod.h contains the macro dev_t makedev(int major, int minor) which packs the ... |

mm(5) -- the MM macro package for formatting documents
|
|
This package provides a formatting capability for a very wide variety of documents. The manner in which a document is typed in and edited is essentially independent of whether the document is to be eventually formatted at a terminal or is to be phototypeset. See the references below for further details. The -mm option causes nroff(1) and troff to use the non-compacted version of the macro package. |
|
mman(5) -- memory mapping definitions
|
|
The header defines the following symbolic constants for use with the madvise() function: MADV_NORMAL No further special treatment. MADV_RANDOM Expect random page references. MADV_SEQUENTIAL Expect sequential page references. MADV_WILLNEED Will need these pages. MADV_DONTNEED Will not need these pages. MADV_SPACEAVAIL Ensure that resources are reserved. The following symbolic constants... |
|
msgmap(5) -- number of entries in the System V IPC message space resource map
|
|
The msgmap tunable specifies the size of (number of entries in) the message space resource map that tracks the free space in shared IPC message space. Each resource map entry is an offset-space pair which points to the offset and size (bytes) of each contiguous series of unused message space "segments". If the map is full when message segments are released (e.g., by msgrcv()), the system issues ... |
|
msgmax(5) -- maximum System V IPC message size in bytes
|
|
The msgmax tunable specifies the maximum allowable size, in bytes, of any single message in a System V message queue. msgmax must be no larger than msgmnb (the size of a queue) nor can it be larger than the preallocated system-wide message storage space (msgssz*msgseg). Possible strategies for deciding this tunable value include setting it equal to msgmnb (one message per queue) or the size of the... |
|
msgmnb(5) -- maximum number of bytes on a single System V IPC message queue
|
|
The msgmnb tunable specifies the maximum allowable total combined size, in bytes, of all messages queued in a single given System V IPC message queue at any one time. If a msgsnd() system call attempts to exceed the limit imposed by msgmnb, it will block (or return [EAGAIN] if IPC_NOWAIT was specified) until a caller of msgrcv() decreases the number of bytes in the queue sufficiently such that the... |
