Core dumps can save the context (state) of a process at a given state for returning to it later. Systems can be made highly available by transferring core between processors, sometimes via core dump files themselves. Core can also be dumped onto a remote host over a network (which is a security risk). [11]
This is a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
In a "dual kernel" layout, kdump uses kexec to boot another kernel and obtain a memory dump. [3]: 10 In the event of a kernel crash, kdump preserves system consistency by booting another Linux kernel, which is known as the dump-capture kernel, and using it to export and save a memory dump.
IPCS (Interactive Problem Control System) is a z/OS component which can analyze unformatted application dumps dumps (SYSMDUMP) or snapshot dumps, or stand-alone system dumps (SADMP). IPCS can inspect any storage address in the dump and format system control blocks, providing labels for fields. It can be run interactively or as a batch job. [2]
Profiles everything running on the Linux system, including hard-to-profile programs such as interrupt handlers and the kernel itself. Sampling profiler for Linux that counts cache misses, stalls, memory fetches, etc. Open Source GPLv2 Oracle Solaris Studio Performance Analyzer: Linux, Solaris C, C++, Fortran, Java; MPI: Performance and memory ...
An ELF file has two views: the program header shows the segments used at run time, whereas the section header lists the set of sections.. In computing, the Executable and Linkable Format [2] (ELF, formerly named Extensible Linking Format) is a common standard file format for executable files, object code, shared libraries, and core dumps.
The GNU Core Utilities or coreutils is a package of GNU software containing implementations for many of the basic tools, such as cat, ls, and rm, which are used on Unix-like operating systems. In September 2002, the GNU coreutils were created by merging the earlier packages textutils , shellutils , and fileutils , along with some other ...
In response to this challenge, more tools in this generation, specifically designed to analyze memory dumps, were created - such as MoonSols, KntTools, the FATKit, VolaTools, and Volatility. [1] These tools had knowledge of the operating system's internal data structures , and were thus capable of reconstructing the operating system's process ...
