bufcache_max_pct(5) -- TO BE OBSOLETED
|
|
These tunables, traditionally used for sizing a static buffer cache, are deprecated. The recommended way to configure a static buffer cache is to set the tunables dbc_min_pct and dbc_max_pct to the same value. Please refer to dbc_min_pct(5) and dbc_max_pct(5), or consult HP support for more information. Note that bufpages and nbuf were specified in units of 4K physical pages, and dbc_min_pct and d... |

chanq_hash_locks(5) -- size of hashed pool of spinlocks protecting the channel queue hash tables
|
|
This tunable should NOT be changed. The default value is the best choice for optimal system performance. This tunable controls the size of a pool of spinlocks (kernel data structures used for synchronization) that also protect channel queues. A very small value increases the probability of collisions in the channel queue hash tables and degrading performance. Very large values are unnecessary. Who... |

This file contains declarations of all the functions in the Complex Library (described in Section (3M)). It defines the types extended The Itanium-based system 80-bit double-extended type. quad An IEEE 754-compliant, 128-bit floating-point type. On HP-UX, quad is a synonym for long double. It defines the macros complex Expands to _Complex, a keyword designating complex types. imaginary Expands to ... |

core_addshmem_read(5) -- determines the inclusion of readable shared memory in a process core dump
|
|
The core_addshmem_read tunable was added in response to a problem where a customer was limited in debugging a user-level process crash because shared memory segments were not written as part of the core file. Upon core dump, the sections of user memory labeled as shared readonly are written (along with the normal data sections) if this tunable is set to 1 (on), and left out if it is set to 0 (off)... |

core_addshmem_write(5) -- determines the inclusion of read/write shared memory in process core dump
|
|
The core_addshmem_write tunable was added in response to a problem where a customer was limited in debugging a user-level process crash because shared memory segments were not written as part of the core file. Upon core dump, the sections of user memory labeled as shared readwrite are written (along with the normal data sections) if this tunable is set to 1 (on), and left out if it is set to 0 (of... |

create_fastlinks(5) -- configure the system to use fast symbolic links
|
|
When create_fastlinks is nonzero, it causes the system to create HFS symbolic links in a manner that reduces the number of disk-block accesses by one for each symbolic link in a path name lookup. This involves a slight change in the HFS disk format, which makes any disk formatted for fast symbolic links unusable on Series 700 systems prior to HP-UX Release 9.0 and Series 800 systems prior to HP-UX... |

csacsa(5) -- calendar and appointment services definitions

The csa/csa.h header defines the following data types through typedef: typedef short int CSA_sint16; typedef long int CSA_sint32; typedef unsigned char CSA_uint8; typedef unsigned short int CSA_uint16; typedef unsigned long int CSA_uint32; typedef void * CSA_buffer; typedef CSA_uint32 CSA_entry_handle; typedef CSA_uint32 CSA_session_handle; typedef char * CSA_string; typedef CSA_string CSA_attribu... |

dbc_max_pct(5) -- maximum percentage of memory to be used for caching file I/O data and metadata
|
|
During file-system I/O operations, data is stored in a buffer cache, the size of which can be fixed or dynamically allocated. When the parameters dbc_min_pct and dbc_max_pct are different, the size of the buffer cache grows or shrinks dynamically depending on competing requests for system memory. The value of dbc_max_pct specifies the maximum percentage of physical memory that may be consumed by t... |

dbc_min_pct(5) -- minimum percentage of memory used for caching file I/O data and metadata

During file-system I/O operations, data is stored in a buffer cache, the size of which can be fixed or dynamically allocated. When the parameters dbc_min_pct and dbc_max_pct are different, the size of the buffer cache grows or shrinks dynamically depending on competing requests for system memory.

default_disk_ir(5) -- enable/disable the use of a device's write cache in the SCSI subsystem
|
|
This tunable enables (1) or disables (0) the Immediate Reporting behavior of the SCSI subsystem, also known as Write Cache Enable (WCE). With Immediate Reporting enabled, disk drives that have data caches return from a write() system call, including raw writes, when the data is cached, rather than returning after the data is written to the media. This sometimes improves write performance especiall... |

dirent(5) -- format of directory streams and directory entries
|
|
This header file defines data types used by the directory stream routines described in directory(3C). The following data types are defined: DIR A structure containing information about an open directory stream. struct dirent A structure defining the format of entries returned by the readdir() function (see directory(3C)). The struct dirent structure includes the following members: char d_name[MAXN... |

dld.sl(5) -- dynamic loader
|
|
The /usr/lib/pa20_64/dld.sl program is the PA-RISC 64-bit dynamic loader. The /usr/lib/dld.sl program is the PA-RISC 32-bit dynamic loader. In programs that use shared libraries, dld.sl is invoked automatically at startup time by exec on PA-RISC 64-bit systems and by the startup file crt0.o on PA-RISC 32-bit systems. Identical copies of crt0.o are kept in both /opt/langtools/lib and /usr/ccs/lib d... |

dld.so(5) -- dynamic loader
|
|
The /usr/lib/hpux64/dld.so shared library is the 64-bit dynamic loader. The /usr/lib/hpux32/dld.so shared library is the 32-bit dynamic loader. In programs that use shared libraries, dld.so is invoked automatically at startup time. /usr/ccs/lib/hpux64/crt0.o is the 64-bit run-time startup file. /usr/ccs/lib/hpux32/crt0.o is the 32-bit run-time startup file. The /usr/lib/hpux32/uld.so and /usr/lib/... |

dma32_pool_size(5) -- the amount of memory to reserve for the 32-bit DMA pool
|
|
This tunable specifies the amount of memory in the first 4GB of the physical address space to be reserved for DMA for 32-bit cards. The memory is set aside at boot time and cannot be used for other purposes. This is required only on some Itanium platforms. On platforms where the 32-bit pool is not needed, this value is ignored. The value of this tunable should be set based on the number of 32-bit ... |
