    HP-UX 11i Internals

    HP-UX under the hood: practical insight for optimization and troubleshooting

    To maximize the performance, efficiency, and reliability of your HP-UX sysem, you need to know what's going on under the hood. HP-UX 11i Internals goes beyond generic UNIX internals, showing exactly how HP-UX works in PA-RISC environments.

    HP experts Cooper and Moore systematically illuminate HP-UX kernel data structures and algorithms for memory management, process and thread scheduling, I/O control, files and file systems, resource management, and more. They focus on HP-UX 11i, while also offering valuable insight for those using earlier versions.

  • PA-RISC architecture: register set, virtual memory, key instructions, and procedure calling conventions

  • HP-UX kernel organization: hardware-dependent and independent data structures

  • Process and thread management: proc tables, memory management, scheduling, and the complete process/thread lifecycle

  • System-wide memory resources: allocation and mapping to physical memory

  • HP-UX paging and swapping

  • Files and filesystems: traditional UNIX filesystems, HFS, VFS, and dynamic buffer cache

  • I/O and device management: addressing, DMA, interrupts, device files, I/O configuration, device driver assignments, and I/O request pathways

  • Logical Volume Management (LVM): abstracting physical disks from the disk I/O system

  • HP-UX multiprocessing: challenges, data structures, and interfaces

  • Kernel communication services: semaphores, message queues, shared memory, signals, and the kernel "callout" system

  • Signaling in complex threaded environments

  • System initialization, from vmunix to init: running HP-UX on diverse platforms

  • Whether you administer HP-UX, tune it, troubleshoot it, or write kernel modules for it, you'll find HP-UX 11i Internals indispensable.
