Programming :: Incremental Backup Using DUMP Command - Error "DUMP: Only Level 0 Dumps Are Allowed On A Subdirectory"
Sep 6, 2010I have used Dump Command to dump the application files. For Full backup the level 0 is working fine. For incremental backup I used the level 1 or 2 it is getting the error as
DUMP: Only level 0 dumps are allowed on a subdirectory
DUMP: The ENTIRE dump is aborted.
The code I used

Programming :: Core Dump Issues. Program Crashes But Does Not Generate Core Dump File?
Oct 7, 2009I want to generate core dump files from my program when it crashes. Its a pretty big process and has about 10-11 threads in it.I have followed the documentation to enable core dump by setting ulimit to unlimited etc. I quickly tried "A demo program creating a core dump" from the following webpage, which succeeds in Segfault and dumping a core file in the directory that I configured.However, I tried running my original program and caused it to crash. I did this by making calls to kill(), raise() or the same null pointer access as shown in the webpage above. In each case, my program crashed but did not generate a core dump file. Am I missing something?My program is in C++ and my environment is Redhat 9.0 (kernel 2.4.20)
Going through the "Why do I NOT get a core dump?" section on the same webpage as above, I can see two potential problems. One - there are issues with the suid/sgid (bullet # 6). I am not able to change any settings with suid because my system does not contain either /proc/sys/fs/suid_dumpable or /proc/sys/kernel/suid_dumpableTwo, my program has threads in it and the bullet # 8 is the problem.
Software :: Mysql Full Backup Script Not Archiving The Dump File?
Mar 20, 2011I have a problem with a script i wrote, the script runs fine if manually executed however it doesn't run *fully* when executed via cron
here's the script :
Code:
#!/bin/bash
FILENAME=mysql_full_dump_`date '+%m.%d.%y'`.sql
`which mysqldump` --all-databases -uroot -p************ -h127.0.0.1 > /root/$FILENAME
RETVAL=$?
[code]....
the script resides in /root/bin and the cron entry is as follows:
Code:
0 0 * * * root "/root/bin/mysql_daily.sh"
the result is the .sql file, but it doesn't archive it.
Server :: Dump Kernel - Discovering More Detail?

Jan 11, 2011My application team is asking me to generate the kernel-dump.
Here are details about my server.
OS: RHEL 4.7/32 Bit
Kernel Version: 2.6.9-89.0.23.ELsmp
Processor: Intel(R) Xeon(R) CPU E5520@ 2.27GHz
Hardware: HP Proliant 380G6 series server.
I am using Electric Cloud applications. Sometimes it creates some kernel panic and immediately got rebooted. Kernel-debuginfo rpm is not installed. In some thread, I read the kernel-debuginfo rpm's version should match with the kernel version. In my case I couldn't even find the exact version of kernel-debuginfo version.
Programming :: Process Abruptly Ends Without Any Error Or Dump?
Apr 21, 2010I have a process which runs for a while and then due to some unknown reason ends abruptly without giving a core. I tried looking in the logs and after watching for a pattern am still not 100% sure of the reason. So I was wondering if there is a way to catch the signal which ends the process and print some values in the handler function. I have called the handler for SIGTERM and SIGABRT functions but none of these are getting triggered. I looked online and did not find any other option. Can you please suggest if tehre is any other signal that can be caught for this unknown abrupt termination.

Oct 21, 2010I am developing an application whose executable is generated inside a certain folder hierarchy (say: /DevPath/MyProject/bin). My source code is located in a different branch of this hierarchy (say: /DevPath/MyProject/src). When my app crashes, its core files are stored in /DevPath/MyProject. I'm developing the app on a pc, but running it on a separate platform in which i can only execute it. Folder hierarchy is the same as above on both computers. Usually, when a new executable version is ready, we update both the executable and the source code on the target platform, transferring all the new /DevPath/MyProject folder on it. But sometimes it can really be a bother, so we update only the executable.
1)In the case we only update the executable, keeping an old source code version, and the app generates a core file, can i trust the backtrace produced by gdb in this case? I.e., does gdb need the latest source code files or it just needs the debugging information?
2) (More radical question ) Do i really need to keep the source code on the target platform for core dump analysis or i just need the executable?
Programming :: Core Dump - Right Memory Block To Be Freed
Nov 8, 2010In one of our core dump we have the followings in the core back trace:
#0 0xb77bf947 in raise () from /lib/tls/libc.so.6
#1 0xb77c10c9 in abort () from /lib/tls/libc.so.6
#2 0xb77f56ba in __fsetlocking () from /lib/tls/libc.so.6
#3 0xb77fcf7f in mallopt () from /lib/tls/libc.so.6
#4 0xb77fd022 in free () from /lib/tls/libc.so.6
It occurred in a memory block free operation. From our analysis, there seems no issue relate the the memory block it self. The memory pointer pointed to the right memory block to be freed and the contents of the memory seems right (not corrupted), in one world, there is nothing obviously wrong. Does any one have any ideas what could be wrong when seeing about?
Programming :: Subsequent Calls To Realloc Cause Memory Dump?
Feb 17, 2010I'm trying to write a C program that extends an array to any user inputed size.
Code:
if (arraysize == 0) {
arraysize = (int) pos + 1;
a = (int *) calloc (arraysize,sizeof(int));
for (i = 0 ; i < arraysize ; i++ )
a[i] = -1;
code....
The program dumps with that sequence of inputs everytime, but might dump an input before or after if different positions are requested. Interestingly, when I tested pos = 2000..2008, I got no dumps. So is realloc somehow trying to extend the array into bad space?
Programming :: Core Dump Analysis Require A Program Name / Why Is So?
Jul 21, 2010To analyse a coredump, I need to specify program name/path in GDB/KDevelop. Since the program name along with arguments is also within a core dump, I wonder if it doesn't keep the proper path of program that crashed and so asks for it?

Sep 20, 2010I am trying to port some "C" code from Solaris to Linux. I have a Dell PowerEdge R610 with an Intel Xeon E5504 quad core processor running Red Hat Linux Enterprise 5.3. I am compiling in 64 bit mode. I have managed to get the code compiled and linked, but when I attempt to execute it, I get a core dump in one of the C library calls (like strcpy or printf.)
I have a static library that contains our own code that makes the call to the C library. If I move the library method into the source file with the main method and rename it to be certain that I am executing my method instead of the method in our library, the call succeeds. Eventually another static library call is made that results in a core dump in the shared object. I compile my library code into a static library with gcc as:

Ubuntu :: IBM T40 - Kernel Log Full Of USB Errors
Feb 22, 2010I just got my hands on a IBM Thinkpad T40 with a broken M$ WinXP. I used one of my old Kubuntu Intrepid LiveCDs. When I entered Virtual Console 1, I discovered that the kernel spams my session with errors, forcing me to use KDE Konsole. Later, I discovered that the LiveCD does not install due to read errors, and decided to install LFS. LFS still has that problem, which prevents me from directly booting into it (I don't have X yet, and I can't do a lot on the console with my display getting spammed),

Programming :: Netlink Sockets In Kernel And Ethernet Driver - Kernel Crash
Aug 31, 2010I write the network driver. Transmission of packets in user space I do through netlink socket`s. In user space there is a handling of packets and their transmission on other device (however, it isn't important).
Problem in that any time, packets through the driver in system, and is reverse, are transferred normally. But then there comes the moment when the kernel crash. If to look in syslog it seems to me that comes deadlock. Also I think that it is related with netlink socket`s.
I can't find the information on that anywhere how correctly to use netlink socket`s in kernel space. Can at you will any a reason into the account of synchronization of sockets and the driver in kernel space?
I can give the driver code if it is necessary.
Programming :: Any Particular Distro With Full GCC Dev System?
Mar 18, 2011If you really want to learn C/C++, get set up on a Linux box with a full gcc dev system. I fixed up an old P4 Machine with 2gig ram and 80gig HD to install Linux on. Don't know anything about Linux yet but installing several distros for evaluation, but a thought occured to me. Is there a particular distro that has this "full gcc dev system" in the initial install or is this something that I will have to install after the OS is up and running on the machine? Is one distro better suited for programming than another?

Oct 28, 2010Is there a way to get the full path of a file in C? I have a method that accepts a file name as an argument and is supposed to read the content of the file.

Programming :: Full Screen Java App From Command Line?
Oct 29, 2010I am trying to make a java application run on a barebone computer connected to a tv screen trough hdmi. I want to make this run as light as possible so gnome probably is overkill. currently I'm running fluxbox but I would like to encapsulate video and some other gui stuff in the program and run it command line(trough startup script.) Another way to do this would be running it when fluxbox starts in full screen. But I really don't know how to do this or where to edit the startup script so I can run it. I'm using ubuntu 10.04 server edition and only installed jre, fluxbox, and of course ssh-server.

Jan 7, 2011To create a daemon, you need to execute these 2 lines (among others):Code: init log
umask 0 What do each of these do?I didn't find anything on the 1st line. (The queries returned mostly "the log of the init (process)".)Google cast some light on the 2nd line: By setting the umask to 0, we will have full access to the files generated by the daemon. Even if you aren't planning on using any files, it is a good idea to set the umask here anyway, just in case you will be accessing files on the filesystem.

Apr 30, 2010While using gdb to debug a C++ program. What I'd like is to be able to enter an address (or an expression yielding an address), and a size, and have it simply do a hex dump. Or maybe even like:

Fedora :: 11 System Freeze With Dd Dump
Jul 17, 2009i've got a non-typical problem here. i've got kvm-ed freebsd (its not so important here) stored on a block device - /dev/sdb8. i wanted to install fedora rawhide there but first i thought it's a good idea to do some backup. so here we go dd if=/dev/sdb8 of=freebsd.img bs=4k
theoretically, dd should do the thing without saying a word, but it doesn't. every time it stops after reaching 16GB filesize (partition is about 35GB) and completely locks the system (only reset helps).the dump worked only once, but when i tried to compress this big image 7z got stucked too and the system froze . the problem occurs when copying to the same drive or to different drive. i've got a partial kerneloops logs, but so far i haven't found the answer.
