Copy large dump file
Hi Experts..
Could anyone please let me know the easier way to copy large dump of files from one server to another. I am trying to copy a set of dump files on two different servers placed in different geographic locations.. Though there are other factors such as latency, etc., slowing up the process, i am curious to know if there are any other method to copy it fast.. I am using scp functionality to copy at present..
Thanks in advance !!

Now take an incremental dump

Hi,
my application (actually library) indexes a file of many GB producing tables (arrays of offset and length of the data indexed) for later reuse. The tables produced are pretty big too, so big that I ran out of memory in my process (3GB limit), when indexing more than 8GB of file or so.... (9 Replies)

dump
dump(9E) Driver Entry Points dump(9E)
NAME
dump - dump memory to device during system failure
SYNOPSIS
#include <sys/types.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>
int dump(dev_t dev, caddr_t addr, daddr_t blkno, int nblk);
INTERFACE LEVEL
Solaris specific (Solaris DDI). This entry point is required. For drivers that do not implement dump() routines, nodev(9F) should be used.
ARGUMENTS
dev Device number.
addr Address for the beginning of the area to be dumped.
blkno Block offset to dump memory.
nblk Number of blocks to dump.
DESCRIPTION
dump() is used to dump a portion of virtual address space directly to a device in the case of system failure. It can also be used for
checking the state of the kernel during a checkpoint operation. The memory area to be dumped is specified by addr (base address) and nblk
(length). It is dumped to the device specified by dev starting at offset blkno. Upon completion dump() returns the status of the transfer.
When the system is panicking, the calls of functions scheduled by timeout(9F) and ddi_trigger_softintr(9F) will never occur. Neither can
delay(9F) be relied upon, since it is implemented via timeout(). See ddi_in_panic(9F).
dump() is called at interrupt priority.
RETURN VALUES
dump() returns 0 on success, or the appropriate error number.
