Chapter 5 Operations after OS Installation

5.1 Memory Dump / Paging File
Setting
Before starting operating this server, configure the setting for obtaining memory
dump.
Memory dump
Debugging information, when memory dump has been set, will be automatically saved in case that a
STOP error (fatal system error) occurs in the system. Error causes may be apparent by analyzing the
saved memory dump.
When a large-capacity memory is installed, care shall be exercised to configure the settings of the
memory dump file. The settings for obtaining memory dump should be configured after installing the
files to be used for operations (OS, applications, etc.).

5.1.1 How to Obtain Memory Dump

Check the following settings before starting configuration to obtain memory dump.
Checking hard disk free space
To obtain memory dump, sufficient hard disk capacity is required for creating paging files and memory
dump files. The obtainable dump types and required hard disk capacity are as follows.
Complete memory (full) dump (recommended)
When the system unexpectedly stops, contents of the whole system memory are recorded. The file is
stored in the directory displayed in the [Dump file] box.
• Paging file: Installed physical memory + 11MB (Recommended: Installed physical memory × 1.5)
• Memory dump file: Equivalent to installed physical memory
Complete memory dump can not be used on the computer in which more than 2GB memory is
installed.
Kernel memory dump
Information of only kernel memory space is recorded. The file is stored in the directory displayed in the
[Dump file] box. Capacity required for kernel memory dump is as follows.
• Paging file: Depending on installed physical memory amount
For memory of 256 to 1,373MB - Installed physical memory × 1.5
For memory of 1,374MB or more - 32-bit system: 2GB + 16MB, 64-bit system: Installed physical
memory + 128MB
• Memory dump file: Depending on the kernel-mode address space being used during STOP
