• WLS Console Timeout

  - by john.graves(at)oracle.com

  The WebLogic console timeout is a great feature for security, yet a horrible feature during development.  Logging in over and over again gets to be annoying.  This is very easy to change, but I would never do this on a production system!   Find the WebLogic consoleapp weblogic.xml file.  This is typically in your WL_HOME/server/lib/consoleapp/webapp/WEB-INF/ directory. Edit the weblogic.xml file: Update the section shown and increase the timeout-secs.  I just throw an extra zero at the end giving me ten full hours of fun!!!: <session-descriptor> <timeout-secs>36000</timeout-secs> <invalidation-interval-secs>60</invalidation-interval-secs> <cookie-name>ADMINCONSOLESESSION</cookie-name> <cookie-max-age-secs>-1</cookie-max-age-secs> <cookie-http-only>false</cookie-http-only> <url-rewriting-enabled>false</url-rewriting-enabled> </session-descriptor> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; }

• How to increase the disk cache of Windows 7

  - by Mark Christiaens

  Under Windows 7 (64 bit), I'm reading through 9000 moderately sized files. In total, there is more than 200 MB of data. Using Java (JDK 1.6.21) I'm iterating over the files. The first 1400 or so go at full speed but then speed drops off to 4ms per file. It turns out that the main cost is incurred simply by opening the files. I'm opening the files using new FileInputStream (and of course closing them in time to avoid file leaks). After some investigating, I see that Windows' disk cache is using only 100 MB or so of RAM although I have 8 GiB available. I've tried increasing the cache size using the CacheSet tool but any values I provide are considered out of range. I've also tried enabling the LargeSystemCache registry key but (after rebooting) the CacheSet tool still indicates I'm using 100 MB of cache (and doesn't increase during the test run). Does anybody have any suggestions to "encourage" Windows 7 to cache my 9000 files?

• Shell script with ImageMagick: hangs forever?

  - by AP257

  I've generated a shell script that uses ImageMagick to convert and crop around 18000 images. Here's a sample entry (so there are 18000 of these): if [ ! -f ./cropped/16333-1.png ] then convert -crop 724x118+876+1989 ./lin/34.png ./cropped/16333-1.png echo cropping 16333-1 fi if [ ! -f ./cropped/16333-1_thumb.png ] then convert -define jpeg:size=400x100 ./cropped/16333-1.png -thumbnail '400x100>' -background transparent -gravity center -extent 400x100 ./cropped/16333-1_thumb.png echo thumbing 16333-1 fi The script only runs for about 2000 images before hanging forever. Am I missing something, or leaking memory somewhere? Thanks for your help!

• rsync to EC2: Identity file not accessible

  - by Richard

  I'm trying to rsync a file over to my EC2 instance: rsync -Paz --rsh "ssh -i ~/.ssh/myfile.pem" --rsync-path "sudo rsync" file.pdf [email protected]:/home/ubuntu/ This gives the following error message: Warning: Identity file ~/.ssh/myfile.pem not accessible: No such file or directory.

• What contributes to smooth online video streaming?

  - by Wesley

  I had a general question about streaming videos online; in particular, on YouTube. What really is required to smoothly stream videos at 360p or 480p? Then for that HD goodness, what really allows a computer to smoothly stream 720p and 1080p? I'm not too sure whether it's to do with the CPU (speed, # cores, cache size), GPU (chipset, VRAM, memory type) or even HDD (IDE vs SATA). What contributes to the ability to stream regular videos and, furthermore, high-definition videos online?

• Flickering when accessing texture by offset

  - by TravisG

  I have this simple compute shader that basically just takes the input from one image and writes it to another. Both images are 128/128/128 in size and glDispatchCompute is called with (128/8,128/8,128/8). The source images are cleared to 0 before this compute shader is executed, so no undefined values should be floating around in there. (I have the appropriate memory barrier on the C++ side set before the 3D texture is accessed). This version works fine: #version 430 layout (location = 0, rgba16f) uniform image3D ping; layout (location = 1, rgba16f) uniform image3D pong; layout (local_size_x = 8, local_size_y = 8, local_size_z = 8) in; void main() { ivec3 sampleCoord = gl_GlobalInvocationID.xyz; imageStore(pong, imageLoad(ping,sampleCoord)); } Reading values from pong shows that it's just a copy, as intended. However, when I load data from ping with an offset: #version 430 layout (location = 0, rgba16f) uniform image3D ping; layout (location = 1, rgba16f) uniform image3D pong; layout (local_size_x = 8, local_size_y = 8, local_size_z = 8) in; void main() { ivec3 sampleCoord = gl_GlobalInvocationID.xyz; imageStore(pong, imageLoad(ping,sampleCoord+ivec3(1,0,0))); } The data that is written to pong seems to depend on the order of execution of the threads within the work groups, which makes no sense to me. When reading from the pong texture, visible flickering occurs in some spots on the texture. What am I doing wrong here?

• Alternative to WMP for mp3 player sync

  - by Dan Neely

  I've been using WMP to sync to my Creative Zen since I bought it a year ago. It worked fine when my collection was still smaller than its capacity, but that's no longer the case, and I can't find any way to specify which music should be synced/not synced. WMP's sync by alphabetical order is an unacceptable option. What I think I want is something that would show my collection organized by artist/album/song (with file size info) in a treeview with checkboxes that saves my selections so I just have make adjustments as needed with new albums instead of having to rebuild my list from scratch every time.

• Cannot see boot options after editing grub background

  - by cipricus

  After solving this problem I managed to get myself into truble again out of nothing by trying to change the display of the dual boot option page in Boot Customizer. I have changed the background, the fonts size (I have increased them) and font style (I have chosen UnDotum). But Boot Customizer gave me an error (I mean a message that the application was closed unexpectedly or smth). I have restarted BootCustomizer and the settings were there. When I rebooted, instead of the normal boot options list, just the background image that I had selected and nothing else. I used Boot Repair to repair grub, it says it did it successfully, but I still get the background image when I try to boot. Any ideas? (Could it be the matter that I chose UnDotum font style? That was installed in Lubuntu - but how could it be accessible in displaying boot options?) The contents of etc/default/grub are: # If you change this file, run 'update-grub' afterwards to update # /boot/grub/grub.cfg. # For full documentation of the options in this file, see: # info -f grub -n 'Simple configuration' GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" # Uncomment to enable BadRAM filtering, modify to suit your needs # This works with Linux (no patch required) and with any kernel that obtains # the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...) #GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef" # Uncomment to disable graphical terminal (grub-pc only) #GRUB_TERMINAL=console # The resolution used on graphical terminal # note that you can use only modes which your graphic card supports via VBE # you can see them in real GRUB with the command `vbeinfo' #GRUB_GFXMODE=640x480 # Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux #GRUB_DISABLE_LINUX_UUID=true # Uncomment to disable generation of recovery mode menu entries #GRUB_DISABLE_RECOVERY="true" # Uncomment to get a beep at grub start #GRUB_INIT_TUNE="480 440 1" I have tried to modify etc/default/grub: GRUB_HIDDEN_TIMEOUT=0 to 10 GRUB_HIDDEN_TIMEOUT_QUIET=true to false and GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to "" but it doesn't help Also, using Shift doesn't make the list visible.

• Adding operation in middle of complex sequence diagram in visio 2003

  - by James

  I am using Microsoft Visio 2003 to define static classes with operations/methods and a sequence diagrams referring to these classes. The sequence diagram is almost done, but i realized that i missed one operation in middle of the diagram. When i try to move rest of the sequences down by selecting it as a block, all the operations in the block loose link with static diagrams. ( Methods which were referred to static classes as fun(), became fun, which means that now they no longer refer to static diagrams and any future changes would not be reflected in dynamic sequence diagrams automatically.) The sequence diagrams have grown to A3 size paper and i have many of such diagrams which needs correction. Manually moving the operations one by one would involve lots of effort. Could someone kindly suggest a way to overcome this problem?

• Driver for writing to UDF partitions from Windows XP?

  - by davr

  I'm considering using an UDF partition to share data between Windows XP, 7, and Linux. It's more efficient than FAT32, and avoids the 4GB max file size limit. I've found it will also work with Mac OS X, more details in this questions. However, in Windows XP, it is read-only. I'd like to write to it too. Are there any drivers that will allow this? I've found a few that support writing UDF...but they are designed for writing to CDs or DVDs, not specifically for HDDs or USB Flash drives: DLA, InCD, Drag-To-Disc. Will any of those 3 drivers work for HDDs/USB Flash drives? Or is there another driver that will do what I want? Thanks.

• dd clone hard drive: Input/Output Error though "chkdsk" says OK

  - by unknown (google)

  Hi, I've used dd to clone hard drives before using 'dd' and a live cd, but have run into a problem. The issue: dd fails with an "Input/Output Error" on /dev/sda3 , even though windows "check disk" (chkdsk) says it's ok. Context: Trying to replace my laptop hard drive w/ a faster one of the same size Laptop has NTFS on a 320gb hard drive Booting into knoppix Knoppix recognizes 'original' drive (/dev/sda) I am using a usb connection for ‘new' drive (irrelevant, but just an fyi) Knoppix recognizes the usb drive as /dev/sdb Using dd, as follows: dd if=/dev/sda of=/dev/sdb "dd" gives the I/O error above at 82Gb (out of 320Gb) I then tried checking each partition as follows and found it failed on /dev/sda3: dd if=/dev/sda1 of=/dev/null dd if=/dev/sda2 of=/dev/null dd if=/dev/sda3 of=/dev/null I have ran windows xp chkdsk on the offending drive in both "find only" and "find and fix" mode and it reports no errors Question How can I find and fix the error on my original hard drive partition (i.e. /dev/sda3) so that dd reads it successfully?

• Making a perfect map (not tile-based)

  - by Sri Harsha Chilakapati

  I would like to make a map system as in the GameMaker and the latest code is here. I've searched a lot in google and all of them resulted in tutorials about tile-maps. As tile maps do not fit for every type of game and GameMaker uses tiles for a different purpose, I want to make a "Sprite Based" map. The major problem I had experienced was collision detection being slow for large maps. So I wrote a QuadTree class here and the collision detection is fine upto 50000 objects in the map without PixelPerfect collision detection and 30000 objects with PixelPerferct collisions enabled. Now I need to implement the method "isObjectCollisionFree(float x, float y, boolean solid, GObject obj)". The existing implementation is becoming slow in Platformer games and I need suggestions on improvement. The current Implementation: /** * Checks if a specific position is collision free in the map. * * @param x The x-position of the object * @param y The y-position of the object * @param solid Whether to check only for solid object * @param object The object ( used for width and height ) * @return True if no-collision and false if it collides. */ public static boolean isObjectCollisionFree(float x, float y, boolean solid, GObject object){ boolean bool = true; Rectangle bounds = new Rectangle(Math.round(x), Math.round(y), object.getWidth(), object.getHeight()); ArrayList<GObject> collidables = quad.retrieve(bounds); for (int i=0; i<collidables.size(); i++){ GObject obj = collidables.get(i); if (obj.isSolid()==solid && obj != object){ if (obj.isAlive()){ if (bounds.intersects(obj.getBounds())){ bool = false; if (Global.USE_PIXELPERFECT_COLLISION){ bool = !GUtil.isPixelPerfectCollision(x, y, object.getAnimation().getBufferedImage(), obj.getX(), obj.getY(), obj.getAnimation().getBufferedImage()); } break; } } } } return bool; } Thanks.

• Why does a zip file appear larger than the source file especially when it is text?

  - by PeanutsMonkey

  I have a text file that is 19 bytes in size and having compressed the file using zip and 7zip, it appears to be larger. I had a read of the question on Why is a 7zipped file larger than the raw file? as well as Why doesn't ZIP Compression compress anything? but considering the file is not already compressed I would have expected further compression. Attached is a screenshot. EDIT0 I took the example further by creating a file that contained random data as follows dd if=/dev/urandom of=sample.log bs=1G count=1 and attempted to compress the file using both zip and 7zip however there were no compression gains. Why is that?

• Recursively resize images from one directory tree to another?

  - by davr

  I have a large complex directory tree full of JPG images. I would like to create a second directory tree that exactly mirrors the first, but resizing all the images down to a set size (say 2000x1500 or something) and quality (perhaps 85%). Is there any tool that would allow me to easily do this on Windows? I could write some scripts to automate it with bash and image magick, but first want to see if it's already been done. Faster is better too, as I have thousands of images. So something like Photoshop is probably not a good solution as it might take a couple of seconds per image.

• Finding Image resolution in PDF file?

  - by Dave

  I have a problem of having some users creating very large PDFs. On the other hands I have PDF sent from our fax machines that are really small in size and totally printable. My question is Is there any way I can find the resolution (DPI) of the PDF. I search the internet, could not find any answer. Checked the properties of the file, this information was not stored there, at least in my case. What is the optimum resolution of converting text file into image PDF. 96dpi, 300dpi or more ? Fun question. Can I resize a PDF which was scanned with high dpi into smaller dpi? I know some answers might not be available as I have already searched the internet and could not find answers. Note: My PDF are entirely images, text to images. I am also familiar with primoPDF (free) something you can experiment with

• Queries regarding Geometry Shaders

  - by maverick9888

  I am dealing with geometry shaders using GL_ARB_geometry_shader4 extension. My code goes like : GLfloat vertices[] = { 0.5,0.25,1.0, 0.5,0.75,1.0, -0.5,0.75,1.0, -0.5,0.25,1.0, 0.6,0.35,1.0, 0.6,0.85,1.0, -0.6,0.85,1.0, -0.6,0.35,1.0 }; glProgramParameteriEXT(psId, GL_GEOMETRY_INPUT_TYPE_EXT, GL_TRIANGLES); glProgramParameteriEXT(psId, GL_GEOMETRY_OUTPUT_TYPE_EXT, GL_TRIANGLE_STRIP); glLinkProgram(psId); glBindAttribLocation(psId,0,"Position"); glEnableVertexAttribArray (0); glVertexAttribPointer(0, 3, GL_FLOAT, 0, 0, vertices); glDrawArrays(GL_TRIANGLE_STRIP,0,4); My vertex shader is : #version 150 in vec3 Position; void main() { gl_Position = vec4(Position,1.0); } Geometry shader is : #version 150 #extension GL_EXT_geometry_shader4 : enable in vec4 pos[3]; void main() { int i; vec4 vertex; gl_Position = pos[0]; EmitVertex(); gl_Position = pos[1]; EmitVertex(); gl_Position = pos[2]; EmitVertex(); gl_Position = pos[0] + vec4(0.3,0.0,0.0,0.0); EmitVertex(); EndPrimitive(); } Nothing is rendered with this code. What exactly should be the mode in glDrawArrays() ? How does the GL_GEOMETRY_OUTPUT_TYPE_EXT parameter will affect glDrawArrays() ? What I expect is 3 vertices will be passed on to Geometry Shader and using those we construct a primitive of size 4 (assuming GL_TRIANGLE_STRIP requires 4 vertices). Can somebody please throw some light on this ?

• Backup Linux Root Partition (Fedora 12)

  - by SomeNewbie

  I setup my partition scheme to have an extra partition the size of my / partion. I have a separate home directory partition. Essentially, I will be doing things that might make my OS unstable so I'd like to backup the OS state but without bothering my home directory. Can I just backup (maybe with dd?) my root partition to another partition on the HDD? I know to restore it I would have to boot up with a livecd or something and do the reverse procedure. I want this to be as simple and require the least amount of external hardware as possible.

• Checking for orphaned snapshots - ESXi5

  - by Tim Alexander

  So we had some issues with our passive mail node over the weekend doing vmtools updates and to resolve a problem we had to revert to a snapshot and then reseed all the databases across. All in all everything seemed fine, the server works and CCR copy status is running fine. I used the "Delete All" option this morning to remove the snapshot and the process according to vCenter has completed with no errors and no "Needs Consolidation" flag. This all seems fine until I check the Datastore that holds the VM on our SAN and I can clearly see snapshots that are pretty big [see attached image]. These do not seem to be changing size and the data modified is around the time the works were started for the vmtools update. Does this possibly mean that at some stage, possibly during reversion or hard resetting of the VM, that they have become orphaned? Are there any methods to check orphaned status of snapshots? We are running ESXi5.0 Update 1 with storage provide by an EMC SAN. Enterprise plus is the license level.

• Why is the latency on one LVM volume consistently higher?

  - by David Schmitt

  I've got a server with LVM over RAID1. One of the volumes has a consistently higher IO latency (as measured by the diskstats_latency munin plugin) than the other volumes from the same group. As you can see, the dark orange /root volume has consistently high IO latency. Actually ten times the average latency of the physical devices. It also has the highest Min and Max values. My main concern are not the peaks, which occur under high load, but the constant load on (semi-)idle. The server is running Debian Squeeze with the VServer kernel and has four VServer containers and one KVM guest. I'm looking for ways to fix - or at least understand - this situation. Here're some parts of the system configuration: root@kvmhost2:~# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/system--host-root 19G 3.8G 14G 22% / tmpfs 16G 0 16G 0% /lib/init/rw udev 16G 224K 16G 1% /dev tmpfs 16G 0 16G 0% /dev/shm /dev/md0 942M 37M 858M 5% /boot /dev/mapper/system--host-isos 28G 19G 8.1G 70% /srv/isos /dev/mapper/system--host-vs_a 30G 23G 6.0G 79% /var/lib/vservers/a /dev/mapper/system--host-vs_b 5.0G 594M 4.1G 13% /var/lib/vservers/b /dev/mapper/system--host-vs_c 5.0G 555M 4.2G 12% /var/lib/vservers/c /dev/loop0 4.4G 4.4G 0 100% /media/debian-6.0.0-amd64-DVD-1 /dev/loop1 4.4G 4.4G 0 100% /media/debian-6.0.0-i386-DVD-1 /dev/mapper/system--host-vs_d 74G 55G 16G 78% /var/lib/vservers/d root@kvmhost2:~# cat /proc/mounts rootfs / rootfs rw 0 0 none /sys sysfs rw,nosuid,nodev,noexec,relatime 0 0 none /proc proc rw,nosuid,nodev,noexec,relatime 0 0 none /dev devtmpfs rw,relatime,size=16500836k,nr_inodes=4125209,mode=755 0 0 none /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000 0 0 /dev/mapper/system--host-root / ext3 rw,relatime,errors=remount-ro,data=ordered 0 0 tmpfs /lib/init/rw tmpfs rw,nosuid,relatime,mode=755 0 0 tmpfs /dev/shm tmpfs rw,nosuid,nodev,relatime 0 0 fusectl /sys/fs/fuse/connections fusectl rw,relatime 0 0 /dev/md0 /boot ext3 rw,sync,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-isos /srv/isos ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_a /var/lib/vservers/a ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_b /var/lib/vservers/b ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/mapper/system--host-vs_c /var/lib/vservers/c ext3 rw,relatime,errors=continue,data=ordered 0 0 /dev/loop0 /media/debian-6.0.0-amd64-DVD-1 iso9660 ro,relatime 0 0 /dev/loop1 /media/debian-6.0.0-i386-DVD-1 iso9660 ro,relatime 0 0 /dev/mapper/system--host-vs_d /var/lib/vservers/d ext3 rw,relatime,errors=continue,data=ordered 0 0 root@kvmhost2:~# cat /proc/mdstat Personalities : [raid1] md1 : active raid1 sda2[0] sdb2[1] 975779968 blocks [2/2] [UU] md0 : active raid1 sda1[0] sdb1[1] 979840 blocks [2/2] [UU] unused devices: <none> root@kvmhost2:~# iostat -x Linux 2.6.32-5-vserver-amd64 (kvmhost2) 06/28/2012 _x86_64_ (8 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 3.09 0.14 2.92 1.51 0.00 92.35 Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 23.25 161.12 7.46 37.90 855.27 1596.62 54.05 0.13 2.80 1.76 8.00 sdb 22.82 161.36 7.36 37.66 850.29 1596.62 54.35 0.54 12.01 1.80 8.09 md0 0.00 0.00 0.00 0.00 0.14 0.02 38.44 0.00 0.00 0.00 0.00 md1 0.00 0.00 53.55 198.16 768.01 1585.25 9.35 0.00 0.00 0.00 0.00 dm-0 0.00 0.00 0.48 20.21 16.70 161.71 8.62 0.26 12.72 0.77 1.60 dm-1 0.00 0.00 3.62 10.03 28.94 80.21 8.00 0.19 13.68 1.59 2.17 dm-2 0.00 0.00 0.00 0.00 0.00 0.00 9.17 0.00 9.64 6.42 0.00 dm-3 0.00 0.00 6.73 0.41 53.87 3.28 8.00 0.02 3.44 0.12 0.09 dm-4 0.00 0.00 17.45 18.18 139.57 145.47 8.00 0.42 11.81 0.76 2.69 dm-5 0.00 0.00 2.50 46.38 120.50 371.07 10.06 0.69 14.20 0.46 2.26 dm-6 0.00 0.00 0.02 0.10 0.67 0.81 12.53 0.01 75.53 18.58 0.22 dm-7 0.00 0.00 0.00 0.00 0.00 0.00 7.99 0.00 11.24 9.45 0.00 dm-8 0.00 0.00 22.69 102.76 407.25 822.09 9.80 0.97 7.71 0.39 4.95 dm-9 0.00 0.00 0.06 0.08 0.50 0.62 8.00 0.07 481.23 11.72 0.16 root@kvmhost2:~# ls -l /dev/mapper/ total 0 crw------- 1 root root 10, 59 May 11 11:19 control lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm1 -> ../dm-4 lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm2 -> ../dm-3 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-isos -> ../dm-2 lrwxrwxrwx 1 root root 7 May 11 11:19 system--host-root -> ../dm-0 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-swap -> ../dm-9 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_d -> ../dm-8 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_b -> ../dm-6 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_c -> ../dm-7 lrwxrwxrwx 1 root root 7 Jun 5 15:06 system--host-vs_a -> ../dm-5 lrwxrwxrwx 1 root root 7 Jun 5 15:08 system--host-kvm3 -> ../dm-1 root@kvmhost2:~#

• Zero-channel RAID for High Performance MySQL Server (IBM ServeRAID 8k) : Any Experience/Recommendation?

  - by prs563

  We are getting this IBM rack mount server and it has this IBM ServeRAID8k storage controller with Zero-Channel RAID and 256MB battery backed cache. It can support RAID 10 which we need for our high performance MySQL server which will have 4 x 15000K RPM 300GB SAS HDD. This is mission-critical and we want as much bandwidth and performance. Is this a good card or should we replace with another IBM RAID card? IBM ServeRAID 8k SAS Controller option provides 256 MB of battery backed 533 MHz DDR2 standard power memory in a fixed mounting arrangement. The device attaches directly to IBM planar which can provide full RAID capability. Manufacturer IBM Manufacturer Part # 25R8064 Cost Central Item # 10025907 Product Description IBM ServeRAID 8k SAS - Storage controller (zero-channel RAID) - RAID 0, 1, 5, 6, 10, 1E Device Type Storage controller (zero-channel RAID) - plug-in module Buffer Size 256 MB Supported Devices Disk array (RAID) Max Storage Devices Qty 8 RAID Level RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 1E Manufacturer Warranty 1 year warranty

• How do I backup my Ubuntu 9.10 system and then restore it to a new machine with different hardware?

  - by EricJLN

  I have a nicely configured Ubuntu 9.10 machine, with crossover linux (from Codeweavers) installed. I have the Nvidia drivers installed. Everything is just as I want it. Now I want to move to a new machine with different hardware: different sized hard drive, different size RAM, different video card, etc. I tried the technique suggested on Ubuntu forums, "Howto: Backup and restore your system!". The results: New system complains about swap not being found New system complains about not finding Nvidia hardware, and I can't open the System-Administration-Hardware Drivers application (i.e., /usr/bin/jockey-gtk) to fix the problem. As result of nvidia, X-Windows is throwing errors, and the on screen process for fixing X-Windows isn't working. How do I restore a backup of my old system, including my Crossover Linux installation, to a new machine with different hardware installed?

• SBSMonitoring.mdf reached limit

  - by Bastien974

  I have SBS 08 Standart. I have some Error in my Event Viewer with MSSQL$SBSMONITORING Event id 1105, 1827: Could not allocate space for object 'dbo.EventLog'.'PK_EventLog' in database 'SBSMonitoring' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. CREATE DATABASE or ALTER DATABASE failed because the resulting cumulative database size would exceed your licensed limit of 4096 MB per database. I tried to schrink the database, worked for SBSMonitoring_log.LDF but nothing for the SBSMonitoring.mdf, still 4096MB. I don't know how to reinstall the monitoring. Thanks for your help.

• Which network performance management software do you use?

  - by Jamie Keeling

  Hello, I am looking at the various options available for network performance management software, some of the solutions I've found so far are: Proprietary: HP - ProCurve Universal: SolarWinds - Orion Open Source: OpenNMS I am trying to discover the benefits of each package over the other and reasons as to why you would go for one (Such as size of the network, overall cost etc..). I'm curious as to which ones other people use and why? Each customer has their own needs and requirements and it would be great to hear some of yours. Thank you for your time.
