• How can I repair my USB drive?

  - by yurko

  USB drive is in read only state and I can't repair it. First of all I tried erase it using dd: root@yurko-laptop:/home/yurko-laptop# ls -l /dev/disk/by-id | grep usb lrwxrwxrwx 1 root root 9 ??? 18 23:45 usb-Generic_Flash_Disk_C173828A-0:0 -> ../../sdb lrwxrwxrwx 1 root root 10 ??? 18 23:45 usb-Generic_Flash_Disk_C173828A-0:0-part1 -> ../../sdb1 root@yurko-laptop:/home/yurko-laptop# dd if=/dev/zero of=/dev/sdb dd: ?????? ? «/dev/sdb»: ?? ?????????? ????????? ????? 8257537+0 ??????? ??????? 8257536+0 ??????? ???????? ??????????? 4227858432 ?????

• Some apps very slow to load on Windows 7, copy & paste very slow.

  - by Mike

  Hello, I searched here and couldn't find a similar issue to mine but apologies if I missed it. I've searched the web and no one else seems to be having the same issue either. I'm running Windows 7 Ultimate 64bit on a pretty high spec. machine (well, apart from the graphics): Asus M4A79T Deluxe AMD Phenom II 965 black edition (quad core, 3.4GHz) 8GB Crucial Ballistix DDR 1333MHz RAM 80GB Intex X25 SSD for OS 500GB mechanical drive for data. ATi Radeon HD 4600 series PCI-e Be Quiet! 850W PSU I think those are all the relevant stats, if you need anything else let me know. I've updated chipset, graphics and various other drivers all to no avail, the problem remains. I have also unplugged and replugged every connection internally and cleaned the RAM edge connectors. The problems: Video LAN (VLC) and CDBurnerXP both take ages to load, I'm talking 30 seconds and 1 minute respectively which is really not right. Copy and paste from Open Office spread sheet into Fire Fox, for example, is really, really slow, I'll have pressed control V 5 or 6 times before it actually happens, if I copy and then wait 5 to 10 seconds or so it'll paste first time so it's definitely some sort of time lag. Command and Conquer - Generals: Zero Hour. When playing it'll run perfectly for about 10 or 20 seconds then it'll just pause for 3 or 4 then run for another 10 or 20 seconds and pause again and so on. I had the Task Manager open on my 2nd monitor whilst playing once and I noticed it was using about 25% of the CPU, pretty stable but when the pause came another task didn't shoot up to 100% like others on the web have been reporting (similar but not the same as my issue, often svchost.exe for them) but dropped to 2 or 3% usage then back up to 25% when it started playing properly again. Very odd! But it gets even odder... I had a BSOD and reboot last week, when it rebooted the problem had completely gone, I could play C&C to my heart's content and both the other apps loaded instantly, copy and paste worked instantly too. I did an AVG update earlier this week which required a reboot, rebooted and the problem's back. I don't think it's AVG related though, I think it was just coincidence that's the app that required a reboot. I think any reboot would have brought the issue back. A number of reboots later and it hasn't gone away again. If any one could make any suggestions as to the likely cause and solution to these issues I'd be most grateful, it's driving me nuts! Thanks, Mike....

• LDAP installed, running, but can't connect remotely [Ubuntu 10.10]

  - by Casey Jordan

  Hi all, I installed LDAP on my ubuntu 10.10 system, using the tutorial found here: https://help.ubuntu.com/10.10/serverguide/C/openldap-server.html Everything seems to be working well, when logged into the server via ssh I can run commands like: > ldapsearch -xLLL -b "dc=easydita,dc=com" uid=john sn givenName cn dn: uid=john,ou=people,dc=easydita,dc=com sn: Doe givenName: John cn: John Doe So I think that's a good sign that things are working well. However I have had zero luck connecting to the server remotely via GUI tools or command line. I have tied JXplorer, and LDAP administration tool. Running commands like this: > ldapsearch -xLLL -W -H ldap://ice.rit.edu -d1 "dc=easydita,dc=com" ldap_url_parse_ext(ldap://ice.rit.edu) ldap_create ldap_url_parse_ext(ldap://ice.rit.edu:389/??base) Enter LDAP Password: ldap_sasl_bind ldap_send_initial_request ldap_new_connection 1 1 0 ldap_int_open_connection ldap_connect_to_host: TCP ice.rit.edu:389 ldap_new_socket: 3 ldap_prepare_socket: 3 ldap_connect_to_host: Trying 127.0.0.1:389 ldap_pvt_connect: fd: 3 tm: -1 async: 0 ldap_open_defconn: successful ldap_send_server_request ber_scanf fmt ({it) ber: ber_scanf fmt ({i) ber: ber_flush2: 34 bytes to sd 3 ldap_result ld 0xb8940170 msgid 1 wait4msg ld 0xb8940170 msgid 1 (infinite timeout) wait4msg continue ld 0xb8940170 msgid 1 all 1 ** ld 0xb8940170 Connections: * host: ice.rit.edu port: 389 (default) refcnt: 2 status: Connected last used: Thu Mar 17 19:42:29 2011 ** ld 0xb8940170 Outstanding Requests: * msgid 1, origid 1, status InProgress outstanding referrals 0, parent count 0 ld 0xb8940170 request count 1 (abandoned 0) ** ld 0xb8940170 Response Queue: Empty ld 0xb8940170 response count 0 ldap_chkResponseList ld 0xb8940170 msgid 1 all 1 ldap_chkResponseList returns ld 0xb8940170 NULL ldap_int_select read1msg: ld 0xb8940170 msgid 1 all 1 ber_get_next ber_get_next: tag 0x30 len 16 contents: read1msg: ld 0xb8940170 msgid 1 message type bind ber_scanf fmt ({eAA) ber: read1msg: ld 0xb8940170 0 new referrals read1msg: mark request completed, ld 0xb8940170 msgid 1 request done: ld 0xb8940170 msgid 1 res_errno: 49, res_error: <>, res_matched: <> ldap_free_request (origid 1, msgid 1) ldap_parse_result ber_scanf fmt ({iAA) ber: ber_scanf fmt (}) ber: ldap_msgfree ldap_err2string ldap_bind: Invalid credentials (49) I am pretty sure that I set up the admin password correctly, but the tutorial was not very specific about that.

• Areca 1280ml RAID6 volume set failed

  - by Richard

  Today we hit some kind of worst case scenario and are open to any kind of good ideas. Here is our problem: We are using several dedicated storage servers to host our virtual machines. Before I continue, here are the specs: Dedicated Server Machine Areca 1280ml RAID controller, Firmware 1.49 12x Samsung 1TB HDDs We configured one RAID6-set with 10 discs that contains one logical volume. We have two hot spares in the system. Today one HDD failed. This happens from time to time, so we replaced it. Upon rebuilding a second disc failed. Normally this is no fun. We stopped heavy IO-operations to ensure a stable RAID rebuild. Sadly the hot-spare disc failed while rebuilding and the whole thing stopped. Now we have the following situation: The controller says that the raid set is rebuilding The controller says that the volume failed It is a RAID 6 system and two discs failed, so the data has to be intact, but we cannot bring the volume online again to access the data. While searching we found the following leads. I don't know whether they are good or bad: Mirroring all the discs to a second set of drives. So we would have the possibility to try different things without loosing more than we already have. Trying to rebuild the array in R-Studio. But we have no real experience with the software. Pulling all drives, rebooting the system, changing into the areca controller bios, reinserting the HDDs one-by-one. Some people are saying that the brought the system online by this. Some are saying that the effect is zero. Some say, that they blew the whole thing. Using undocumented areca commands like "rescue" or "LeVel2ReScUe". Contacting a computer forensics service. But whoa... primary estimates by phone exceeded 20.000€. That's why we would kindly ask for help. Maybe we are missing the obvious? And yes of course, we have backups. But some systems lost one week of data, thats why we'd like to get the system up and running again. Any help, suggestions and questions are more than welcome.

• what can cause a folder to become indestructible?

  - by JustJeff

  I have a directory that I want to delete, but windows (xp sp3) is giving me the run-around and the folder is now effectively indestructible. Attempts to open the folder, either via explorer or cmd.exe are met with 'd:/temp/foo Is Not Accessible. Access is denied'. Attempts to delete the folder result in 'Cannot delete foo: The directory is not empty' So I can't delete it because supposedly it's not empty, but windows won't let me in it for some reason, so I can't clean it out first. There's nothing in it of consequence, and basically I just want to delete it at this point. Thinking that some other process must have a lock on it, I used the SysInternals 'handles' and Process Explorer to look for open handles with the directory name. These turned up no matches. (The directory name is not actually 'foo', it is something more unique but 'foo' is easier to type here). I put the machine through a restart, and the problem persists. I did a search for the folder name with regedit, to see what other apps might be aware of it. No match. The properties dialog was mildly interesting. The Read-Only attribute is 'semi-checked', i.e., the grayish check mark you get when some parts are and some parts aren't. Naturally I immediately unchecked this, and tried to delete the folder. No go. Opening properties again reveals the gray check mark next to Read-Only has returned. All the stats, size, size on disk, files, folders, all these are zero. There do not appear to be any shares on the folder, so that's not it either. Finally, I tried opening the partition's properties, and running the Tools/Error Checking utility. This didn't turn up any problems either. Fwiw, this directory was created by [a popular gui zip tool] when I tried to unpack a tar-and-zipped archive created on another system with command line utils. The archive was definitely corrupt, but I've never seen such a file do anything worse than crash the zip app, and certainly never leave permanent glitches in the file system. So what else can possibly be going on to make this folder behave this way?

• Open a terminal window & run command, then close the terminal window if command completed successfully?

  - by Caspar

  I'm trying to write a script to do the following: Open a terminal window which runs a long running command (Ideally) move the terminal window to the top left corner of the screen using xdotool Close the terminal window only if the long running command exited with a zero return code To put it in Windows terms, I'd like to have the Linux equivalent of start cmd /c long_running_cmd if long_running_cmd succeeds, and do the equivalent of start cmd /k long_running_cmd if it fails. What I have so far is a script which starts xterm with a given command, and then moves the window as desired: #!/bin/bash # open a new terminal window in the background with the long running command xterm -e ~/bin/launcher.sh ./long_running_cmd & # move the terminal window (requires window process to be in background) sleep 1 xdotool search --name launcher.sh windowmove 0 0 And ~/bin/launcher.sh is intended to run whatever is passed as a command line argument to it: #!/bin/bash # execute command line arguments $@ But, I haven't been able to get the xterm window to close after long_running_cmd is done. I think something like xterm -e ~/bin/launcher.sh "./long_running_cmd && kill $PPID" & might be what I'm after, so that xterm is launched in the background and it runs ./long_running_cmd && kill $PPID. So the shell in the xterm window then runs the long running command and if it completes successfully, the parent process of the shell (i.e. the process owning the xterm window) is killed, thereby closing the xterm window. But, that doesn't work: nothing happens, so I suspect my quoting or escaping is incorrect, and I haven't been able to fix it. An alternate approach would be to get the PID of long_running_cmd, use wait to wait for it to finish, then kill the xterm window using kill $! (since $! refers to last task started in the background, which will be the xterm window). But I can't figure out a nice way to get the PID & exit value of long_running_cmd out of the shell running in the xterm window and into the shell which launched the xterm window (short of writing them to a file somewhere, which seems like it should be unnecessary?). What am I doing wrong, or is there an easier way to accomplish this?

• APC File Cache not working but user cache is fine

  - by danishgoel

  I have just got a VPS (with cPanel/WHM) to test what gains i could get in my application with using apc file cache AND user cache. So firstly I got the PHP 5.3 compiled in as a DSO (apache module). Then installed APC via PECL through SSH. (First I tried with WHM Module installer, it also had the same problem, so I tried it via ssh) All seemed fine and phpinfo showed apc loaded and enabled. Then I checked with apc.php. All seemed OK But as I started testing my php application, the stats in apc for File Cache Information state: Cached Files 0 ( 0.0 Bytes) Hits 1 Misses 0 Request Rate (hits, misses) 0.00 cache requests/second Hit Rate 0.00 cache requests/second Miss Rate 0.00 cache requests/second Insert Rate 0.00 cache requests/second Cache full count 0 Which meant no PHP files were being cached, even though I had browsed through over 10 PHP files having multiple includes. So there must have been some Cached Files. But the user cache is functioning fine. User Cache Information Cached Variables 0 ( 0.0 Bytes) Hits 1000 Misses 1000 Request Rate (hits, misses) 0.84 cache requests/second Hit Rate 0.42 cache requests/second Miss Rate 0.42 cache requests/second Insert Rate 0.84 cache requests/second Cache full count 0 Its actually from an APC caching test script which tries to retrieve and store 1000 entries and gives me the times. A sort of simple benchmark. Can anyone help me here. Even though apc.cache_by_default = 1, no php files are being cached. This is my apc config Runtime Settings apc.cache_by_default 1 apc.canonicalize 1 apc.coredump_unmap 0 apc.enable_cli 0 apc.enabled 1 apc.file_md5 0 apc.file_update_protection 2 apc.filters apc.gc_ttl 3600 apc.include_once_override 0 apc.lazy_classes 0 apc.lazy_functions 0 apc.max_file_size 1M apc.mmap_file_mask apc.num_files_hint 1000 apc.preload_path apc.report_autofilter 0 apc.rfc1867 0 apc.rfc1867_freq 0 apc.rfc1867_name APC_UPLOAD_PROGRESS apc.rfc1867_prefix upload_ apc.rfc1867_ttl 3600 apc.serializer default apc.shm_segments 1 apc.shm_size 32M apc.slam_defense 1 apc.stat 1 apc.stat_ctime 0 apc.ttl 0 apc.use_request_time 1 apc.user_entries_hint 4096 apc.user_ttl 0 apc.write_lock 1 Also most php files are under 20KB, thus, apc.max_file_size = 1M is not the cause. I have also tried using 'apc_compile_file ' to force some files into opcode cache with no luck. I have also re-installed APC with Debugging enabled, but nothing shows in the error_log I have also tried setting mmap_file_mask to /dev/zero and /tmp/apc.xxxxxx, i have also set /tmp permissions to 777 to no avail Any clue anyone. Update: I have tried following things and none cause APC file cache to populate 1. set apc.enable_cli = 1 AND run a script from cli 2. Set apc.max_file_size = 5M (just in case) 3. switched php handler from dso to FastCGI in WHM (then switched it back to dso as it did not solve the problem) 4. Even tried restarting the container

• Loss of wireless network connectivity when playing video via HDMI cable

  - by Jeff Fohl

  Hi Folks - New to Super User, so I hope this question fits in with the guidelines. Very strange problem I am having, and I am at a loss as to how to continue troubleshooting this one. The basic problem is that when I attempt to watch streamed video on a particular display device (an Optoma HD180 projector), my network connectivity drops like a stone to barely measurable levels. This is my setup: I have a Dell H2C 730x running Windows 7 64bit. This particular computer has two ATI Radeon HD 4800 video cards. I have two Samsung 22" monitors connected to one card, and an Optoma HD180 digital projector connected to the other card via an HDMI cable. My internet connection is normally a reliable 6Mbps. The problem I am having occurs when I stream video (or even just browse the web) on the Optoma Projector. When I do this, my internet connection drops to practically zero (just a few kilobits per second). When I move the browser away from the projector, and over to one of my Samsung monitors, the internet connection comes right back. Note that the Optoma projector is on and enabled as a third monitor all this time. I can move the mouse around on the projector without triggering the problem. I tried pinging my router when I was playing a movie on one of the monitors, and I get a 1 millisecond response. However, when I have the movie playing on the Optoma projecter, pinging the router gives me response times in the hundreds of milliseconds, or times out completely. So, it clearly is something local to my machine - and not some sort of throttling occurring down the line. I would think that it is possibly something to do with the HDMI driver conflicting somehow with my network driver (which is a USB-based wireless connection). This one has me really stumped. Anyone have any ideas? EDIT: I am now leaning towards the possibility that the HDMI cable is somehow interfering with the wireless network, when large amounts of data are being pushed through the cable. Is this possible?

• Unable to burn Windows ISO from Fedora

  - by user331947

  First of all, English is not my native tongue, so apologies for any mistakes. My computer recently started prompting that it can't launch Windows successfully. So I just choose start Windows normally. Then, I found that the startup freezes at the Windows screen (before the login prompt). I have tried rebooting several times and get the same results. So I just gave up. After few days, I tried to boot up my laptop again. This time it got to the desktop, but it's extremely slow and the icons on my Desktop don't show up. I decided to format the Windows partition and reinstall a new one. (It is usually faster that way since I kept my 400GB+ data on aother partition and programs and the rest in the same partition as Windows). The thing is I get the Windows disc at the moment (Traveling aboard). But I have a Windows 7 disc image on my hard disk. So, I downloaded Ubuntu 14.04 LTS, made a Live USB, and then try to burn the image from Ubuntu. But the program just freezes and I don't know why. I tried several times and it's still the same. So I tried using Fedora instead, just to see if it will work. The Disk Image Writer report something like this. Error unmounting /dev/dm-0: Command-line `umount "/dev/dm-0"' exited with non-zero exit status 32: umount: /: target is busy (In some cases useful info about processes that use the device is found by lsof(8) or fuser(1).) (udisks-error-quark, 14) Also, I tried installing linux on the windows partition. The installation program freezes (both Ubuntu and Fedora). So, I thought that maybe something are wrong with my hard disk. I seek the solution on the internet and found that gparted can be used to format a partition. And it also froze at "Searching /dev/sda/ partition ...". I'm using Lenovo Y570. Spec below. http://www.notebookreview.com/notebookreview/lenovo-ideapad-y570-review-a-lenovo-bestseller/3/ Can anyone suggest a next step in diagnosing and fixing this problem? Thanks in advance.

• Windows 2003 Server Caching

  - by pablomedok

  We're experiencing almost everyday table index corruption on Windows Server 2003. We are running an old application which uses DBF/CDX tables. Everything was fine for ages, but 6 months after we've installed Advantage Database Server (which allows access to some tables to our website) we started to get index corruption problems. And we don't know whom to blame. We've tried to exclude all possible causes of this corruption. Now all users work in terminal mode - so no network problems can cause that, OpLocks also can't be a reason. We changed hardware, network cards, switches, reainstalled Server and even moved to new dedicated server. The only thing we can't exclude is ADS - because it should be working. Is that possible that local read/write caching that causes that problem? E.g. one user or process uses cached data, later another user/process changes it, and later the first user changes it again without knowing about the first change. Is it possible theoretically? Is it possible that this problem is caused by imporper file server or caching settings? Is it possible that normal users use non-cached data and ADS is using cached data? Or vice versa? Is it possible that each terminal user has its own cache? Or maybe the problem is about RAID caching somehow interfering with Windows Server caching? Or maybe there are some special settings for Windows Server for working with DBF tables that are being written simultaneously by several terminal users? Maybe there is a way to turn off caching for some certain files to check it? Sometimes we get index crash twice a day, sometimes everything is fine for 5 days in a row. Today only one user was working in the evening with the database (usually there are 30-50 users are working simultaneously on working hours). So it's almost zero load on server. , Syncronization with website is performed every 5 minutes during work hours and every 15 minutes in the evening and on weekend. We've done file access auditing and it shows that during website syncroniztions ADS server opens the table and index files for ReadEA and WriteEA though it performs only SELECT queries. ADS does UPDATE/INSERT queries but less freqently - not during regular synchronizations, but only when an order is placed by website visitor). Please help me. We are struggling with this problem for almost a year and still can't find any pattern or any clue about this problem. Here is my previous qestion about this issue on DBA: http://dba.stackexchange.com/questions/8646/foxpro-dbf-index-corruption

• Linux software RAID6: 3 drives offline - how to force online?

  - by Ole Tange

  This is similar to 3 drives fell out of Raid6 mdadm - rebuilding? except that it is not due to a failing cable. Instead the 3rd drive fell offline during rebuild of another drive. The drive failed with: kernel: end_request: I/O error, dev sdc, sector 293732432 kernel: md/raid:md0: read error not correctable (sector 293734224 on sdc). After rebooting both these sectors and the sectors around them are fine. This leads me to believe the error is intermittent and thus the device simply took too long to error correct the sector and remap it. I expect that no data was written to the RAID after it failed. Therefore I hope that if I can kick the last failing device online that the RAID is fine and that the xfs_filesystem is OK, maybe with a few missing recent files. Taking a backup of the disks in the RAID takes 24 hours, so I would prefer that the solution works the first time. I have therefore set up a test scenario: export PRE=3 parallel dd if=/dev/zero of=/tmp/raid${PRE}{} bs=1k count=1000k ::: 1 2 3 4 5 parallel mknod /dev/loop${PRE}{} b 7 ${PRE}{} \; losetup /dev/loop${PRE}{} /tmp/raid${PRE}{} ::: 1 2 3 4 5 mdadm --create /dev/md$PRE -c 4096 --level=6 --raid-devices=5 /dev/loop${PRE}[12345] cat /proc/mdstat mkfs.xfs -f /dev/md$PRE mkdir -p /mnt/disk2 umount -l /mnt/disk2 mount /dev/md$PRE /mnt/disk2 seq 1000 | parallel -j1 mkdir -p /mnt/disk2/{}\;cp /bin/* /mnt/disk2/{}\;sleep 0.5 & mdadm --fail /dev/md$PRE /dev/loop${PRE}3 /dev/loop${PRE}4 cat /proc/mdstat # Assume reboot so no process is using the dir kill %1; sync & kill %1; sync & # Force fail one too many mdadm --fail /dev/md$PRE /dev/loop${PRE}1 parallel --tag -k mdadm -E ::: /dev/loop${PRE}? | grep Upda # loop 2,5 are newest. loop1 almost newest => force add loop1 Next step is to add loop1 back - and this is where I am stuck. After that do a xfs-consistency check. When that works, check that the solution also works on real devices (such a 4 USB sticks).

• c# Truncate HTML safely for article summary

  - by WickedW

  Hi All, Does anyone have a c# variation of this? This is so I can take some html and display it without breaking as a summary lead in to an article? http://stackoverflow.com/questions/1193500/php-truncate-html-ignoring-tags Save me from reinventing the wheel! Thank you very much ---------- edit ------------------ Sorry, new here, and your right, should have phrased the question better, heres a bit more info I wish to take a html string and truncate it to a set number of words (or even char length) so I can then show the start of it as a summary (which then leads to the main article). I wish to preserve the html so I can show the links etc in preview. The main issue I have to solve is the fact that we may well end up with unclosed html tags if we truncate in the middle of 1 or more tags! The idea I have for solution is to a) truncate the html to N words (words better but chars ok) first (be sure not to stop in the middle of a tag and truncate a require attribute) b) work through the opened html tags in this truncated string (maybe stick them on stack as I go?) c) then work through the closing tags and ensure they match the ones on stack as I pop them off? d) if any open tags left on stack after this, then write them to end of truncated string and html should be good to go!!!! -- edit 12112009 Here is what I have bumbled together so far as a unittest file in VS2008, this 'may' help someone in future My hack attempts based on Jan code are at top for char version + word version (DISCLAIMER: this is dirty rough code!! on my part) I assume working with 'well-formed' HTML in all cases (but not necessarily a full document with a root node as per XML version) Abels XML version is at bottom, but not yet got round to fully getting tests to run on this yet (plus need to understand the code) ... I will update when I get chance to refine having trouble with posting code? is there no upload facility on stack?

• Python script is exiting with no output and I have no idea why

  - by Adam Tuttle

  I'm attempting to debug a Subversion post-commit hook that calls some python scripts. What I've been able to determine so far is that when I run post-commit.bat manually (I've created a wrapper for it to make it easier) everything succeeds, but when SVN runs it one particular step doesn't work. We're using CollabNet SVNServe, which I know from the documentation removes all environment variables. This had caused some problems earlier, but shouldn't be an issue now. Before Subversion calls a hook script, it removes all variables - including $PATH on Unix, and %PATH% on Windows - from the environment. Therefore, your script can only run another program if you spell out that program's absolute name. The relevant portion of post-commit.bat is: echo -------------------------- >> c:\svn-repos\company\hooks\svn2ftp.out.log set SITENAME=staging set SVNPATH=branches/staging/wwwroot/ "C:\Python3\python.exe" C:\svn-repos\company\hooks\svn2ftp.py ^ --svnUser="svnusername" ^ --svnPass="svnpassword" ^ --ftp-user=ftpuser ^ --ftp-password=ftppassword ^ --ftp-remote-dir=/ ^ --access-url=svn://10.0.100.6/company ^ --status-file="C:\svn-repos\company\hooks\svn2ftp-%SITENAME%.dat" ^ --project-directory=%SVNPATH% "staging.company.com" %1 %2 >> c:\svn-repos\company\hooks\svn2ftp.out.log echo -------------------------- >> c:\svn-repos\company\hooks\svn2ftp.out.log When I run post-commit.bat manually, for example: post-commit c:\svn-repos\company 12345, I see output like the following in svn2ftp.out.log: -------------------------- args1: c:\svn-repos\company args0: staging.company.com abspath: c:\svn-repos\company project_dir: branches/staging/wwwroot/ local_repos_path: c:\svn-repos\company getting youngest revision... done, up-to-date -------------------------- However, when I commit something to the repo and it runs automatically, the output is: -------------------------- -------------------------- svn2ftp.py is a bit long, so I apologize but here goes. I'll have some notes/disclaimers about its contents below it. #!/usr/bin/env python """Usage: svn2ftp.py [OPTION...] FTP-HOST REPOS-PATH Upload to FTP-HOST changes committed to the Subversion repository at REPOS-PATH.

So there's nothing useful being logged. I'm lost. I've gone way down the rabbit hole on this one, and don't know where to go from here. Any ideas?

• c++ optimize array of ints

  - by a432511

  I have a 2D lookup table of int16_t. int16_t my_array[37][73] = {{**DATA HERE**}} I have a mixture of values that range from just above the range of int8_t to just below the range of int8_t and some of the values repeat themselves. I am trying to reduce the size of this lookup table. What I have done so far is split each int16_t value into two int8_t values to visualize the wasted bytes. int8_t part_1 = original_value >> 4; int8_t part_2 = original_value & 0x0000FFFF; // If the upper 4 bits of the original_value were empty if(part_1 == 0) wasted_bytes_count++; I can easily remove the zero value int8_t that are wasting a byte of space and I can also remove the duplicate values, but my question is how do I do remove those values while retaining the ability to lookup based on the two indices? I contemplated translating this into a 1D array and adding a number following each duplicated value that would represent the number of duplicates that were removed, but I am struggling with how I would then identify what is a lookup value and what is a duplicate count. Also, it is further complicated by stripping out the zero int8_t values that were wasted bytes. EDIT: This array is stored in ROM already. RAM is even more limited than ROM so it is already stored in ROM. EDIT: I am going to post a bounty for this question as soon as I can. I need a complete answer of how to store the information AND retrieve it. It does not need to be a 2D array as long as I can get the same values. EDIT: Adding the actual array below: {150,145,140,135,130,125,120,115,110,105,100,95,90,85,80,75,70,65,60,55,50,45,40,35,30,25,20,15,10,5,0,-4,-9,-14,-19,-24,-29,-34,-39,-44,-49,-54,-59,-64,-69,-74,-79,-84,-89,-94,-99,104,109,114,119,124,129,134,139,144,149,154,159,164,169,174,179,175,170,165,160,155,150},

  If you have never heard of Groupon recently, you probably are not working in the tech industry because it is all over the blogosphere.

• Ask How-To Geek: Learning the Office Ribbon, Booting to USB with an Old BIOS, and Snapping Windows

  - by Jason Fitzpatrick

  You’ve got questions and we’ve got answers. Today we highlight how to master the new Office interface, USB boot a computer with outdated BIOS, and snap windows to preset locations. Learning the New Office Ribbon Dear How-To Geek, I feel silly asking this (in light of how long the new Office interface has been out) but my company finally got around to upgrading from Windows XP and Office 2000 so the new interface it totally new to me. Can you recommend any resources for quickly learning the Office ribbon and the new changes? I feel completely lost after two decades of the old Office interface. Help! Sincerely, Where the Hell is Everything? Dear Where the Hell, We think most people were with you at some point in the last few years. “Where the hell is…” could possibly be the slogan for the new ribbon interface. You could browse through some of the dry tutorials online or even get a weighty book on the topic but the best way to learn something new is to get hands on. Ribbon Hero turns learning the new Office features and ribbon layout into a game. It’s no vigorous round of Team Fortress mind you, but it’s significantly more fun than reading a training document. Check out how to install and configure Ribbon Hero here. You’ll be teaching your coworkers new tricks in no time. Boot via USB with an Old BIOS Dear How-To Geek, I’m trying to repurpose some old computers by updating them with lightweight Linux distros but the BIOS on most of the machines is ancient and creaky. How ancient? It doesn’t even support booting from a USB device! I have a large flash drive that I’ve turned into a master installation tool for jobs like this but I can’t use it. The computers in question have USB ports; they just aren’t recognized during the boot process. What can I do? USB Bootin’ in Boise Dear USB Bootin’, It’s great you’re working to breathe life into old hardware! You’ve run into one of the limitations of older BIOSes, USB was around but nobody was thinking about booting off of it. Fortunately if you have a computer old enough to have that kind of BIOS it’s likely to also has a floppy drive or a CDROM drive. While you could make a bootable CDROM for your application we understand that you want to keep using the master USB installer you’ve made. In light of that we recommend PLoP Boot Manager. Think of it like a boot manager for your boot manager. Using it you can create a bootable floppy or CDROM that will enable USB booting of your master USB drive. Make a CD and a floppy version and you’ll have everything in your toolkit you need for future computer refurbishing projects. Read up on creating bootable media with PLoP Boot Manager here. Snapping Windows to Preset Coordinates Dear How-To Geek, Once upon a time I had a company laptop that came with a little utility that snapped windows to preset areas of the screen. This was long before the snap-to-side features in Windows 7. You could essentially configure your screen into a grid pattern of your choosing and then windows would neatly snap into those grids. I have no idea what it was called or if was anymore than a gimmick from the computer manufacturer, but I’d really like to have it on my new computer! Bend and Snap in San Francisco, Dear Bend and Snap, If we had to guess, we’d guess your company must have had a set of laptops from Acer as the program you’re describing sounds exactly like Acer GridVista. Fortunately for you the application was extremely popular and Acer released it independently of their hardware. If, by chance, you’ve since upgraded to a multiple monitor setup the app even supports multiple monitors—many of the configurations are handy for arranging IM windows and other auxiliary communication tools. Check out our guide to installing and configuring Acer GridVista here for more information. Have a question you want to put before the How-To Geek staff?

• SQL SERVER – SSMS: Memory Usage By Memory Optimized Objects Report

  - by Pinal Dave

  At conferences and at speaking engagements at the local UG, there is one question that keeps on coming which I wish were never asked. The question around, “Why is SQL Server using up all the memory and not releasing even when idle?” Well, the answer can be long and with the release of SQL Server 2014, this got even more complicated. This release of SQL Server 2014 has the option of introducing In-Memory OLTP which is completely new concept and our dependency on memory has increased multifold. In reality, nothing much changes but we have memory optimized objects (Tables and Stored Procedures) additional which are residing completely in memory and improving performance. As a DBA, it is humanly impossible to get a hang of all the innovations and the new features introduced in the next version. So today’s blog is around the report added to SSMS which gives a high level view of this new feature addition. This reports is available only from SQL Server 2014 onwards because the feature was introduced in SQL Server 2014. Earlier versions of SQL Server Management Studio would not show the report in the list. If we try to launch the report on the database which is not having In-Memory File group defined, then we would see the message in report. To demonstrate, I have created new fresh database called MemoryOptimizedDB with no special file group. Here is the query used to identify whether a database has memory-optimized file group or not. SELECT TOP(1) 1 FROM sys.filegroups FG WHERE FG.[type] = 'FX' Once we add filegroup using below command, we would see different version of report. USE [master] GO ALTER DATABASE [MemoryOptimizedDB] ADD FILEGROUP [IMO_FG] CONTAINS MEMORY_OPTIMIZED_DATA GO The report is still empty because we have not defined any Memory Optimized table in the database.  Total allocated size is shown as 0 MB. Now, let’s add the folder location into the filegroup and also created few in-memory tables. We have used the nomenclature of IMO to denote “InMemory Optimized” objects. USE [master] GO ALTER DATABASE [MemoryOptimizedDB] ADD FILE ( NAME = N'MemoryOptimizedDB_IMO', FILENAME = N'E:\Program Files\Microsoft SQL Server\MSSQL12.SQL2014\MSSQL\DATA\MemoryOptimizedDB_IMO') TO FILEGROUP [IMO_FG] GO You may have to change the path based on your SQL Server configuration. Below is the script to create the table. USE MemoryOptimizedDB GO --Drop table if it already exists. IF OBJECT_ID('dbo.SQLAuthority','U') IS NOT NULL DROP TABLE dbo.SQLAuthority GO CREATE TABLE dbo.SQLAuthority ( ID INT IDENTITY NOT NULL, Name CHAR(500)  COLLATE Latin1_General_100_BIN2 NOT NULL DEFAULT 'Pinal', CONSTRAINT PK_SQLAuthority_ID PRIMARY KEY NONCLUSTERED (ID), INDEX hash_index_sample_memoryoptimizedtable_c2 HASH (Name) WITH (BUCKET_COUNT = 131072) ) WITH (MEMORY_OPTIMIZED = ON, DURABILITY = SCHEMA_AND_DATA) GO As soon as above script is executed, table and index both are created. If we run the report again, we would see something like below. Notice that table memory is zero but index is using memory. This is due to the fact that hash index needs memory to manage the buckets created. So even if table is empty, index would consume memory. More about the internals of how In-Memory indexes and tables work will be reserved for future posts. Now, use below script to populate the table with 10000 rows INSERT INTO SQLAuthority VALUES (DEFAULT) GO 10000 Here is the same report after inserting 1000 rows into our InMemory table.    There are total three sections in the whole report. Total Memory consumed by In-Memory Objects Pie chart showing memory distribution based on type of consumer – table, index and system. Details of memory usage by each table. The information about all three is taken from one single DMV, sys.dm_db_xtp_table_memory_stats This DMV contains memory usage statistics for both user and system In-Memory tables. If we query the DMV and look at data, we can easily notice that the system tables have negative object IDs.  So, to look at user table memory usage, below is the over-simplified version of query. USE MemoryOptimizedDB GO SELECT OBJECT_NAME(OBJECT_ID), * FROM sys.dm_db_xtp_table_memory_stats WHERE OBJECT_ID > 0 GO This report would help DBA to identify which in-memory object taking lot of memory which can be used as a pointer for designing solution. I am sure in future we will discuss at lengths the whole concept of In-Memory tables in detail over this blog. To read more about In-Memory OLTP, have a look at In-Memory OLTP Series at Balmukund’s Blog.

• SQL SERVER – SSMS: Backup and Restore Events Report

  - by Pinal Dave

  A DBA wears multiple hats and in fact does more than what an eye can see. One of the core task of a DBA is to take backups. This looks so trivial that most developers shrug this off as the only activity a DBA might be doing. I have huge respect for DBA’s all around the world because even if they seem cool with all the scripting, automation, maintenance works round the clock to keep the business working almost 365 days 24×7, their worth is knowing that one day when the systems / HDD crashes and you have an important delivery to make. So these backup tasks / maintenance jobs that have been done come handy and are no more trivial as they might seem to be as considered by many. So the important question like: “When was the last backup taken?”, “How much time did the last backup take?”, “What type of backup was taken last?” etc are tricky questions and this report lands answers to the same in a jiffy. So the SSMS report, we are talking can be used to find backups and restore operation done for the selected database. Whenever we perform any backup or restore operation, the information is stored in the msdb database. This report can utilize that information and provide information about the size, time taken and also the file location for those operations. Here is how this report can be launched.   Once we launch this report, we can see 4 major sections shown as listed below. Average Time Taken For Backup Operations Successful Backup Operations Backup Operation Errors Successful Restore Operations Let us look at each section next. Average Time Taken For Backup Operations Information shown in “Average Time Taken For Backup Operations” section is taken from a backupset table in the msdb database. Here is the query and the expanded version of that particular section USE msdb; SELECT (ROW_NUMBER() OVER (ORDER BY t1.TYPE))%2 AS l1 ,       1 AS l2 ,       1 AS l3 ,       t1.TYPE AS [type] ,       (AVG(DATEDIFF(ss,backup_start_date, backup_finish_date)))/60.0 AS AverageBackupDuration FROM backupset t1 INNER JOIN sys.databases t3 ON ( t1.database_name = t3.name) WHERE t3.name = N'AdventureWorks2014' GROUP BY t1.TYPE ORDER BY t1.TYPE On my small database the time taken for differential backup was less than a minute, hence the value of zero is displayed. This is an important piece of backup operation which might help you in planning maintenance windows. Successful Backup Operations Here is the expanded version of this section.   This information is derived from various backup tracking tables from msdb database.  Here is the simplified version of the query which can be used separately as well. SELECT * FROM sys.databases t1 INNER JOIN backupset t3 ON (t3.database_name = t1.name) LEFT OUTER JOIN backupmediaset t5 ON ( t3.media_set_id = t5.media_set_id) LEFT OUTER JOIN backupmediafamily t6 ON ( t6.media_set_id = t5.media_set_id) WHERE (t1.name = N'AdventureWorks2014') ORDER BY backup_start_date DESC,t3.backup_set_id,t6.physical_device_name; The report does some calculations to show the data in a more readable format. For example, the backup size is shown in KB, MB or GB. I have expanded first row by clicking on (+) on “Device type” column. That has shown me the path of the physical backup file. Personally looking at this section, the Backup Size, Device Type and Backup Name are critical and are worth a note. As mentioned in the previous section, this section also has the Duration embedded inside it. Backup Operation Errors This section of the report gets data from default trace. You might wonder how. One of the event which is tracked by default trace is “ErrorLog”. This means that whatever message is written to errorlog gets written to default trace file as well. Interestingly, whenever there is a backup failure, an error message is written to ERRORLOG and hence default trace. This section takes advantage of that and shows the information. We can read below message under this section, which confirms above logic. No backup operations errors occurred for (AdventureWorks2014) database in the recent past or default trace is not enabled. Successful Restore Operations This section may not be very useful in production server (do you perform a restore of database?) but might be useful in the development and log shipping secondary environment, where we might be interested to see restore operations for a particular database. Here is the expanded version of the section. To fill this section of the report, I have restored the same backups which were taken to populate earlier sections. Here is the simplified version of the query used to populate this output. USE msdb; SELECT * FROM restorehistory t1 LEFT OUTER JOIN restorefile t2 ON ( t1.restore_history_id = t2.restore_history_id) LEFT OUTER JOIN backupset t3 ON ( t1.backup_set_id = t3.backup_set_id) WHERE t1.destination_database_name = N'AdventureWorks2014' ORDER BY restore_date DESC,  t1.restore_history_id,t2.destination_phys_name Have you ever looked at the backup strategy of your key databases? Are they in sync and do we have scope for improvements? Then this is the report to analyze after a week or month of maintenance plans running in your database. Do chime in with what are the strategies you are using in your environments.

• Searching for the last logon of users in Active Directory

  - by Robert May

  I needed to clean out a bunch of old accounts at Veracity Solutions, and wanted to delete those that hadn’t used their account in more than a year. I found that AD has a property on objects called the lastLogonTimestamp.  However, this value isn’t exposed to you in any useful fashion.  Sure, you can pull up ADSI Edit and and eventually get to it there, but it’s painful. I spent some time searching, and discovered that there’s not much out there to help, so I thought a blog post showing exactly how to get at this information would be in order. Basically, what you end up doing is using System.DirectoryServices to search for accounts and then filtering those for users, doing some conversion and such to make it happen.  Basically, the end result of this is that you get a list of users with their logon information and you can then do with that what you will.  I turned my list into an observable collection and bound it into a XAML form. One important note, you need to add a reference to ActiveDs Type Library in the COM section of the world in references to get to LargeInteger. Here’s the class: namespace Veracity.Utilities { using System; using System.Collections.Generic; using System.DirectoryServices; using ActiveDs; using log4net; /// <summary> /// Finds users inside of the active directory system. /// </summary> public class UserFinder { /// <summary> /// Creates the default logger /// </summary> private static readonly ILog log = LogManager.GetLogger(typeof(UserFinder)); /// <summary> /// Finds last logon information /// </summary> /// <param name="domain">The domain to search.</param> /// <param name="userName">The username for the query.</param> /// <param name="password">The password for the query.</param> /// <returns>A list of users with their last logon information.</returns> public IList<UserLoginInformation> GetLastLogonInformation(string domain, string userName, string password) { IList<UserLoginInformation> result = new List<UserLoginInformation>(); DirectoryEntry entry = new DirectoryEntry(domain, userName, password, AuthenticationTypes.Secure); DirectorySearcher directorySearcher = new DirectorySearcher(entry); directorySearcher.PropertyNamesOnly = true; directorySearcher.PropertiesToLoad.Add("name"); directorySearcher.PropertiesToLoad.Add("lastLogonTimeStamp"); SearchResultCollection searchResults; try { searchResults = directorySearcher.FindAll(); } catch (System.Exception ex) { log.Error("Failed to do a find all.", ex); throw; } try { foreach (SearchResult searchResult in searchResults) { DirectoryEntry resultEntry = searchResult.GetDirectoryEntry(); if (resultEntry.SchemaClassName == "user") { UserLoginInformation logon = new UserLoginInformation(); logon.Name = resultEntry.Name; PropertyValueCollection timeStampObject = resultEntry.Properties["lastLogonTimeStamp"]; if (timeStampObject.Count > 0) { IADsLargeInteger logonTimeStamp = (IADsLargeInteger)timeStampObject[0]; long lastLogon = (long)((uint)logonTimeStamp.LowPart + (((long)logonTimeStamp.HighPart) << 32)); logon.LastLogonTime = DateTime.FromFileTime(lastLogon); } result.Add(logon); } } } catch (System.Exception ex) { log.Error("Failed to iterate search results.", ex); throw; } return result; } } } Some important things to note: Username and Password can be set to null and if your computer us part of the domain, this may still work. Domain should be set to something like LDAP://servername/CN=Users,CN=Domain,CN=com You’re actually getting a com object back, so that’s why the LongInteger conversions are happening.  The class for UserLoginInformation looks like this:   namespace Veracity.Utilities { using System; /// <summary> /// Represents user login information. /// </summary> public class UserLoginInformation { /// <summary> /// Gets or sets Name /// </summary> public string Name { get; set; } /// <summary> /// Gets or sets LastLogonTime /// </summary> public DateTime LastLogonTime { get; set; } /// <summary> /// Gets the age of the account. /// </summary> public TimeSpan AccountAge { get { TimeSpan result = TimeSpan.Zero; if (this.LastLogonTime != DateTime.MinValue) { result = DateTime.Now.Subtract(this.LastLogonTime); } return result; } } } } I hope this is useful and instructive.

• Big Data – Role of Cloud Computing in Big Data – Day 11 of 21

  - by Pinal Dave

  In yesterday’s blog post we learned the importance of the NewSQL. In this article we will understand the role of Cloud in Big Data Story What is Cloud? Cloud is the biggest buzzword around from last few years. Everyone knows about the Cloud and it is extremely well defined online. In this article we will discuss cloud in the context of the Big Data. Cloud computing is a method of providing a shared computing resources to the application which requires dynamic resources. These resources include applications, computing, storage, networking, development and various deployment platforms. The fundamentals of the cloud computing are that it shares pretty much share all the resources and deliver to end users as a service.  Examples of the Cloud Computing and Big Data are Google and Amazon.com. Both have fantastic Big Data offering with the help of the cloud. We will discuss this later in this blog post. There are two different Cloud Deployment Models: 1) The Public Cloud and 2) The Private Cloud Public Cloud Public Cloud is the cloud infrastructure build by commercial providers (Amazon, Rackspace etc.) creates a highly scalable data center that hides the complex infrastructure from the consumer and provides various services. Private Cloud Private Cloud is the cloud infrastructure build by a single organization where they are managing highly scalable data center internally. Here is the quick comparison between Public Cloud and Private Cloud from Wikipedia:   Public Cloud Private Cloud Initial cost Typically zero Typically high Running cost Unpredictable Unpredictable Customization Impossible Possible Privacy No (Host has access to the data Yes Single sign-on Impossible Possible Scaling up Easy while within defined limits Laborious but no limits Hybrid Cloud Hybrid Cloud is the cloud infrastructure build with the composition of two or more clouds like public and private cloud. Hybrid cloud gives best of the both the world as it combines multiple cloud deployment models together. Cloud and Big Data – Common Characteristics There are many characteristics of the Cloud Architecture and Cloud Computing which are also essentially important for Big Data as well. They highly overlap and at many places it just makes sense to use the power of both the architecture and build a highly scalable framework. Here is the list of all the characteristics of cloud computing important in Big Data Scalability Elasticity Ad-hoc Resource Pooling Low Cost to Setup Infastructure Pay on Use or Pay as you Go Highly Available Leading Big Data Cloud Providers There are many players in Big Data Cloud but we will list a few of the known players in this list. Amazon Amazon is arguably the most popular Infrastructure as a Service (IaaS) provider. The history of how Amazon started in this business is very interesting. They started out with a massive infrastructure to support their own business. Gradually they figured out that their own resources are underutilized most of the time. They decided to get the maximum out of the resources they have and hence  they launched their Amazon Elastic Compute Cloud (Amazon EC2) service in 2006. Their products have evolved a lot recently and now it is one of their primary business besides their retail selling. Amazon also offers Big Data services understand Amazon Web Services. Here is the list of the included services: Amazon Elastic MapReduce – It processes very high volumes of data Amazon DynammoDB – It is fully managed NoSQL (Not Only SQL) database service Amazon Simple Storage Services (S3) – A web-scale service designed to store and accommodate any amount of data Amazon High Performance Computing – It provides low-tenancy tuned high performance computing cluster Amazon RedShift – It is petabyte scale data warehousing service Google Though Google is known for Search Engine, we all know that it is much more than that. Google Compute Engine – It offers secure, flexible computing from energy efficient data centers Google Big Query – It allows SQL-like queries to run against large datasets Google Prediction API – It is a cloud based machine learning tool Other Players Besides Amazon and Google we also have other players in the Big Data market as well. Microsoft is also attempting Big Data with the Cloud with Microsoft Azure. Additionally Rackspace and NASA together have initiated OpenStack. The goal of Openstack is to provide a massively scaled, multitenant cloud that can run on any hardware. Thing to Watch The cloud based solutions provides a great integration with the Big Data’s story as well it is very economical to implement as well. However, there are few things one should be very careful when deploying Big Data on cloud solutions. Here is a list of a few things to watch: Data Integrity Initial Cost Recurring Cost Performance Data Access Security Location Compliance Every company have different approaches to Big Data and have different rules and regulations. Based on various factors, one can implement their own custom Big Data solution on a cloud. Tomorrow In tomorrow’s blog post we will discuss about various Operational Databases supporting Big Data.

• Connection Pooling is Busted

  - by MightyZot

  A few weeks ago we started getting complaints about performance in an application that has performed very well for many years.  The application is a n-tier application that uses ADODB with the SQLOLEDB provider to talk to a SQL Server database.  Our object model is written in such a way that each public method validates security before performing requested actions, so there is a significant number of queries executed to get information about file cabinets, retrieve images, create workflows, etc.  (PaperWise is a document management and workflow system.)  A common factor for these customers is that they have remote offices connected via MPLS networks. Naturally, the first thing we looked at was the query performance in SQL Profiler.  All of the queries were executing within expected timeframes, most of them were so fast that the duration in SQL Profiler was zero.  After getting nowhere with SQL Profiler, the situation was escalated to me.  I decided to take a peek with Process Monitor.  Procmon revealed some “gaps” in the TCP/IP traffic.  There were notable delays between send and receive pairs.  The send and receive pairs themselves were quite snappy, but quite often there was a notable delay between a receive and the next send.  You might expect some delay because, presumably, the application is doing some thinking in-between the pairs.  But, comparing the procmon data at the remote locations with the procmon data for workstations on the local network showed that the remote workstations were significantly delayed.  Procmon also showed a high number of disconnects. Wireshark traces showed that connections to the database were taking between 75ms and 150ms.  Not only that, but connections to a file share containing images were taking 2 seconds!  So, I asked about a trust.  Sure enough there was a trust between two domains and the file share was on the second domain.  Joining a remote workstation to the domain hosting the share containing images alleviated the time delay in accessing the file share.  Removing the trust had no affect on the connections to the database. Microsoft Network Monitor includes filters that parse TDS packets.  TDS is the protocol that SQL Server uses to communicate.  There is a certificate exchange and some SSL that occurs during authentication.  All of this was evident in the network traffic.  After staring at the network traffic for a while, and examining packets, I decided to call it a night.  On the way home that night, something about the traffic kept nagging at me.  Then it dawned on me…at the beginning of the dance of packets between the client and the server all was well.  Connection pooling was working and I could see multiple queries getting executed on the same connection and ethereal port.  After a particular query, connecting to two different servers, I noticed that ADODB and SQLOLEDB started making repeated connections to the database on different ethereal ports.  SQL Server would execute a single query and respond on a port, then open a new port and execute the next query.  Connection pooling appeared to be broken. The next morning I wrote a test to confirm my hypothesis.  Turns out that the sequence causing the connection nastiness goes something like this: Make a connection to the database. Open a result set that returns enough records to require multiple roundtrips to the server. For each result, query for some other data in the database (this will open a new implicit connection.) Close the inner result set and repeat for every item in the original result set. Close the original connection. Provided that the first result set returns enough data to require multiple roundtrips to the server, ADODB and SQLOLEDB will start making new connections to the database for each query executed in the loop.  Originally, I thought this might be due to Microsoft’s denial of service (ddos) attack protection.  After turning those features off to no avail, I eventually thought to switch my queries to client-side cursors instead of server-side cursors.  Server-side cursors are the default, by the way.  Voila!  After switching to client-side cursors, the disconnects were gone and the above sequence yielded two connections as expected. While the real problem is the amount of time it takes to make connections over these MPLS networks (100ms on average), switching to client-side cursors made the problem go away.  Believe it or not, this is actually documented by Microsoft, and rather difficult to find.  (At least it was while we were trying to troubleshoot the problem!)  So, if you’re noticing performance issues on slower networks, or networks with slower switching, take a look at the traffic in a tool like Microsoft Network Monitor.  If you notice a high number of disconnects, and you’re using fire-hose or server-side cursors, then try switching to client-side cursors and you may see the problem go away. Most likely, Microsoft believes this to be appropriate behavior, because ADODB can’t guarantee that all of the data has been retrieved when you execute the inner queries.  I’m not convinced, though, because the problem remains even after replacing all of the implicit connections with explicit connections and closing those connections in-between each of the inner queries.  In that case, there doesn’t seem to be a reason why ADODB can’t use a single connection from the connection pool to make the additional queries, bringing the total number of connections to two.  Instead ADO appears to make an assumption about the state of the connection. I’ve reported the behavior to Microsoft and am awaiting to hear from the appropriate team, so that I can demonstrate the problem.  Maybe they can explain to us why this is appropriate behavior.  :)
