Performing a Core Dump to a Local Drive
A core dump can be started two ways:
By responding to the core dump choices displayed by NetWare after an
abend has occurred.
The Type? prompt allows you to specify a full core dump or a cacheless
core dump, as explained above.
The Device? prompt allows you to specify a local drive or a DOS-
writeable device.
NOTE:
Other types of core dumps might become possible in the future. Your
Novell Technical Support representative will inform you if that is the case.
By forcing a core dump by entering .C while in the NetWare debugger.
If the server is not completely frozen, you can enter the debugger by
pressing: Shift+Shift+Alt+Esc.
HINT:
Press the left Shift key with the left hand, and press both the right Shift key
and Alt with the right hand. Then press Esc with the most convenient finger of the
left hand.
Then enter .C and the server then displays core dump choices.
When the core dump is finished, enter G to exit the debugger and to
redisplay the System Console prompt. Or enter Q to exit to DOS.
After you start the core dump, you are asked to specify the DOS drive letter
and file path that the memory image file will be written to. The size of the full
image file will be approximately equal to the total RAM installed in the server.
For a cacheless core dump, the size of the image file will be approximately
equal to total RAM minus the amount of file cache (disk cache memory).
The drive can be any writable DOS device that contains enough storage space.
But remember that it must be set up not only before the server abends, but
before the server is booted.
When the image is written to a local hard disk on the server, the default name
of the image file is C:COREDUMP.IMG. After the file is on the hard disk, it
can be compressed, copied to diskettes, backed up to tape, or sent by FTP to
ftp.novell.com (if you have opened a support incident).
The image file can also be written to a network drive later, after the server is
up and running. This can be done using IMGCOPY.NLM or any other third-
party NLM that provides this functionality. To locate IMGCOPY.NLM, use
the search on the Patches and Files page on the Novell Web site (http://
support.novell.com/filefinder/).
