  • How can I resolve Oracle 11g XE connection failure straight after installation?

    - by d3vid
    I have just installed Oracle 11g XE on a Windows 7 VirtualBox VM, using all the default options. "Getting Started" fails When I click on Getting Started I get taken to http://127.0.0.1:8080/apex/f?p=4950 which fails. After some browsing I came across a suggestion to confirm the HTTP port, but I can't get this far, because I can't connect. connect system fails If I select Run SQL command line I get taken to a SQL prompt. I enter connect system and get prompted for a password. I enter the password. I immediately get the following error: ERROR: ORA-01033: ORACLE initialization or shutdown in progress Process ID: 0 Session ID: 0 Serial number: 0 Info: Start database This happens whether or not I run Start database first. (Start database just opens a Windows command prompt window.) Info: Windows services My Oracle services start as follows: Starting the manual services doesn't resolve the problem. Enabling and starting the disabled service doesn't resolve the problem. Is there something I haven't done? How can I resolve this connection error?

  • Why is lassoing ink in OneNote so slow in general? Doesn't anyone care?

    - by GuoLiang Oon
    Now I understand that this is especially an (known) issue in the OneNote 2013 preview and that it will probably be fixed in the final release. But lassoing in OneNote 2010 was no sprightly affair either. I'm just perplexed really, why on earth is there such an issue? Is lassoing intrinsically computationally expensive? OneNote would be soooooooooooo much more useful if there's no lasso lag. And doing a laggy lasso on tablet pcs with weak processors is just so much worse. Or do most folks just don't use the lasso feature much? I use it primarily to shrink intermediate calculations for future retrieval.

  • Why does a wired network slow down with user increase?

    - by Ed Briscoe
    If you had a wired network, 20 PCs hooked up to a 100 Mbit/sec switch (same onboard ethernet port speed) and you were just sending some test data round. What is the technical explanation as to why 20 machines sending test data around this network to each other is slower than one to one? I mean I know a busy network means it's slower but I'm really trying to understand some more technical details. Thanks for any help

  • fail2ban log parsing too slow on Raspberry Pi - options? [migrated]

    - by Gordon Morehouse
    I'm running fail2ban on a Raspberry Pi at 950MHz which I cannot overclock further. The Pi is occasionally subject to SYN floods on particular ports. I've set up iptables to throttle the rate of SYNs on the port of interest; when the throttle limits are exceeded, hosts which send SYNs are dropped into the REJECT chain and the particular SYN packet which exceeded the limit is logged. fail2ban then watches for these logged SYNs and, after seeing a few, temporarily bans the host for a short time (this is a transient issue in the app I'm working with). The problem is that the SYN floods can occasionally reach rates which are too fast for fail2ban to keep up with; I'll see 20-40 log messages per second, and eventually fail2ban falls behind and becomes ineffective. To add insult to injury, it continues consuming a LOT of CPU as it tries to catch up. I have verified that DROP chained packets from hosts already banned by fail2ban are not logged, and thus do not add to its load. What are my options here? I have a few ideas, but no clear path forward. Could I make the log-parse regex "easier" so it takes fewer cycles? Would using iptables --log-prefix to put a token near the start of the log message, and/or otherwise simplifying/altering the fail2ban regex help? Here is the current fail2ban config line containing a regex: failregex = kernel:.*?SRC=(?:::f{4,6}:)?(?P<host>[\w\-.^_]+) DST.*?SYN Is there a faster way for fail2ban to watch for the packets exceeding the limits than parsing kern.log? Could fail2ban be run under PyPy instead of CPython with minimal nonstandard wizardry (the OS is Raspbian 7, so, mostly Debian 7)? Is there something better than fail2ban that I could use to watch for the packets which exceed the SYN limits, and after N exceeds in X seconds, temporarily put the offending IP into the iptables DROP bucket, and take it out when the ban timer expires? Again, I'd vastly prefer a solution that uses as much software available in Debian as possible, though I can build Debian packages in a pinch.

  • mod_jk problem: Tomcat is probably not started or is listening on the wrong port

    - by Konrad
    Hi, I am running some application on Tomcat 6.0.26. There is Apache in front of web server talking to it over mod_jk.

  • World Wide Publishing Service very slow to restart on IIS? Why?

    - by StacMan
    Every now and then, we look to restart our IIS server by restarting the "WWW Publishing Service". On most systems this would usually only take a minute or two, but this can often take up to 10 minutes to stop the server and restart. Does anyone know any way to work out what is taking so much time to stop the service? After reading up around the net I've learned this may be due to locked resources used by users and/or lower-level IIS cached items being recycled. But I cant seem to work out where I can validate if this is true on not. Also if anyone knows how to fix or speed this up, that would be excellent. We have a large codebase which contains over 280 aspx pages across the site. Our main domain contains about 100 aspx pages whilst the subdomains contain 15 or 20 each. Some specs: Code is written in C#; runs on .Net framework 2.0 Server Windows Web Server 2008 IIS7; DB running SQL Server 2008 Standard

  • apache2 and php slow first load on Ubuntu VPS - something like mysqltuner but for apache?

    - by talkingnews
    Ubuntu 10.10 64 bit VPS, 512Mb dedicated RAM. Mysql tuned so that sqltuner is completely happy. Used RAM never above 350Mb out of the 493 available. Load never exceeds 1.04 or so. httpd.conf tuned as per all the guides for vps of that memory - amount of preforks, spares etc. But for the FIRST load a site after having not visited for a while, it's taking ages. First load: Parse Time: 3.576 - Number of Queries: 50 - Query Time: 0.019723195953369 Reload Parse Time: 0.096 - Number of Queries: 39 - Query Time: 0.0066126374511719 Subsequent reloads will be at this speed. htop shows two items as soon as I load that page for the first time: php-cgi /usr/sbin/apache2 -k start I'm using suPHP but I've tried fast-cgi and cgi. Stuck now, a weekend of tweaking has brought me nothing. Advice appreciated.

  • Why is SMB from a Windows 7 64-bit to OS X Server so slow when using DNS vs IP?

    - by chuboy
    When I connect my 64-bit Windows 7 to a OS X server using \servername, my transfer rates are around 400KB/s. However, when I do the same thing using \192.168.0.10 (which is the IP of the server), transfer rates jump to 30MB/s. All of this happens via a gigabit ethernet cable with my wireless disabled I heard Samba itself "doesn't use DNS", but if that's the case, how am I able to connect to the server in the first place?

  • Is VirtualBox really slow compared to the host OS? (for Ruby development)

    - by dan
    I have VirtualBox running Ubuntu as a guest environment on my Macbook Pro running Leopard OS X 10.5. I timed the same batch of Ruby on Rails unit tests on both systems. The difference seems to be quite big. The same suite of Ruby unit tests that take 13.4 seconds in the native OS X, take 82 seconds to run in VirtualBox Ubuntu. Are other people doing the same kind of development noticing the same differences?

  • Reimage PC: Myth or Fact to speeding up a slow PC?

    - by sunpech
    I have a 4-5 year old PC running Windows XP for software development at work. It struggles to run all development tools I need at the same time. Management feels I need to reimage my computer to "speed it up". The last time it was imaged was about 3 years ago. What resources books, websites, blogs, articles, etc are out there that supports/debunks this well known belief that reimaging an old PC running Windows XP will make it faster once again? A resource I remember reading is from Lifehacker.com: Windows Maintenance Tips: The Good, Bad And Useless

  • Database server: Small quick RAM or large slow RAM?

    - by Josh Smeaton
    We are currently designing our new database servers, and have come up with a trade off I'm not entirely sure of how to answer. These are our options: 48GB 1333MHz, or 96GB 1066MHz. My thinking is that RAM should be plentiful for a Database Server (we have plenty and plenty of data, and some very large queries) rather than as quick as it could be. Apparently we can't get 16GB chips at 1333MHz, hence the choices above. So, should we get lots of slower RAM, or less faster RAM? Extra Info: Number of DIMM Slots Available: 6 Servers: Dell Blades CPU: 6 core (only single socket due to Oracle licensing).

  • How to set up a VPN Incoming connection with Windows to tunnel Internet traffic?

    - by Mehrdad
    I want to set up a VPN on a remote server to route all my Internet traffic for privacy reasons. I can set up an incoming connection and connect to it successfully. The problem is, I can just see the remote computer and no other Web sites will open. I want the remote server to act like a NAT. How can I do that? Note that I don't want to split Internet traffic. I actually want to send all the traffic to the remote server but need to make it relay the traffic. For the record, my remote server is Windows Web Server 2008 which does not have routing and remote access service. Clarification I'm mostly interested in server configuration. I don't have any problems configuring the client. By the way, Windows Web Server 2008 seems to have the same VPN features built in client OSes (like Vista) and specifically, it doesn't include the RRAS console in MMC. I'm also open to suggestions regarding third party PPTP/L2TP daemons available, if they are free.

  • 256 SSD / 2TB Internal drive, i7, 16GB RAM.. explorer.exe still slow

    - by web_dvlp_sd
    OK, so I just got done tweaking my brand new PC and explorer.exe still manages to be sluggish not as snappy as I'd like or expected at all. Specs are i7 4th gen processor, 16GB RAM, windows 7 64 home premium on 256GB SSD, secondary internal 2TB drive. I assumed system would be lightning fast, been doing a bunch of researching and switched out a lot of different settings including enabling/disabling indexing, turning pagefile on/off or placing it on separate drive, turning folder optimization options on/off.. changes have been minimal or none at all. Any further advice or anything I might be missing, besides a new/repair install? PC is literally 3 days old I don't feel like I need a new install at all

  • Does AMD Cool n Quiet Slow Down Your System?

    - by Software Monkey
    I discovered today that having AMD Cool n Quiet enabled in my BIOS appears to be slowing down my Windows XP SP2 system by about 29% on memory & CPU intensive workloads. I was wondering if (a) anyone else had encountered this, (b) anyone can offer an explanation, (c) there are any negatives I need to be aware of if I keep AMD CnQ disabled. With some superficial testing so far, I don't immediately notice any difference with CnQ off (other than the performance being what I expected from this new hardware). It seems to ramp up the CPU fan a little bit as my program maxes out 1 core, but that's the same as with CnQ on. And when I let the system idle the CPU fan slows down and the systems as quiet as a mouse (after years of 6 small fans churning like they want to go into orbit it's nice to again have a system where I can hear the HDDs seeking). Bonus question: Does CnQ cause issues with system stability? I ask because the reason I disabled it was because I have had a few freezes and 1 spontaneous reboot with my new hardware.

  • Can many addon domains slow down cPanel or create problems?

    - by Marco Demaio
    I actually resell hosting plans by using one single cPanel account and many addon domains under it. Basically for each new user I don't create a new cP account, but I simply create a new ADDON domain and give him the necessary space. I know in this way the final user won't be able to manage his emails and he won't be able to access all cPanel features, but that's ok. I know in my account I'm allowed to add unlimited addon domains, but adding many addon domains is there something that might happen that slows down cPanel or could create problems? Any suggestions you could give me about the way i'm using cPanel which might not be the usual way of using it. (As for instance: "be aware that mails from different addon domains under the same CP account could create many problems.", etc.) Thanks!

  • Picasa v.3.6.2 for Mac is suddenly very slow - what are the implications of rebuilding my database?

    - by 3rdparty
    Recently Picasa v3.6.2 for Mac has become very sluggish - mainly noticable for any (non destructive) changes made to photos such as starring an image. This action used to be nearly immediate, but recently I've found it can take 1-3 seconds for Picasa to register the change, and become responsive again. I'm considering rebuilding my Picasa database as per these instructions - however I'm concerned I may lose any pre-existing non-destructive (unsaved) edits, along with Picasa albums that I have created. Curious if anyone has experienced Picasa sluggishness with the latest version and/or what their results have been from rebuilding their database. My last resort is to SuperDuper my drive and then rebuild the database, so I can always restore it if I lose critical data.

  • Very Large number of connections in TIME_WAIT state; Server is slow, ipconntrac

    I have a nginx server with load balancing and reverse proxy. Right now its behing another nginx but very soon I plan to make it front, where it will receive TCP connections from clients directly at a rate of 500req/second I am having some big troubles with the server. I have pasted my configurations here and I am kinda sure that the problem is with ipconntrac and similar things which are alient to me http://paste.org/pastebin/view/28543 root@load_balancer:/proc/sys/net/ipv4# netstat -an|awk '/tcp/ {print $6}'|sort|uniq -c 67 CLOSING 727 ESTABLISHED 173 FIN_WAIT1 183 FIN_WAIT2 19 LAST_ACK 5 LISTEN 447 SYN_RECV 1 SYN_SENT 27970 TIME_WAIT Its a ubuntu machine with mainly nginx (load balancer and reverse proxy) installed. It surely isnt great. Can you help me understand whats going on and how can I fix it. This is my live server and I am sure its in a bad shape right now. Any document or commands to fix this, or settings I should make to make this better and reduce time wait and fin_wait1/2 better would be awesome.

  • What does a connection timeout indicate when performing an NFS mount?

    - by DeeDee
    We have a shiny new QNAP NAS (TS-879U-RP), and I'm trying to mount it to our big ol' RHEL server in the same manner as our other two QNAP NAS devices. The IT department won't give me the root privileges to the NAS, so I can't SSH in (I know, I know). The first thing I did was to, via the QNAP web admin interface, create a network share named "Runs." I then added the IP of the RHEL server to the permissions list: On the RHEL server, I then added the following line to /etc/fstab: [IP of NAS]:/Runs /mnt/gsrnas3 nfs defaults 0 0 Aside from the IP and the specific mount directory name, this is how I mounted the other two NAS devices. I then created the gsrnas3 directory under /mnt/, and then ran `mount /mnt/gsrnas3' I got the following error: mount.nfs: Connection timed out My first thought is that it's a ports issue, but I don't have enough specific experience with this issue to know for sure. I have two other NAS devices by the same manufacturer already mounted to this RHEL server, so that leads me to believe the configuration issue is on the NAS side of things. I can ping the NAS device successfully from the RHEL server. Not being able to SSH into said NAS is a huge hassle, though. Any ideas?

  • Scanned JPEGs are large and slow to load - can they be optimized losslessly?

    - by Alistair Knock
    I have hundreds of JPEG photographs which were scanned about 5 years ago from negative using a Konica Minolta DiMAGE Scan Dual IV. The dimensions are ~4500x3000, and the filesize is around 12Mb, compared to shots from a DSLR with dimensions of 3000x2300 and filesize of 2-4Mb (actually, these are the output from a RAW convertor). The filesize is obviously quite a big difference, but the issue that's bothering me is that the (perceived) loading time is at least 10 times slower. Is this size/speed discrepancy likely to be because the scanner software saved the JPEGs inefficiently / using an old compression format, or is it simply that the scanned negatives contain much more "detail" (in the form of grain/noise) than the digital images? If the former, is there a way to losslessly optimize them? I've tried re-exporting the scanned files to full size JPEG from my RAW software but the filesize is pretty much the same. Both files will have been saved at 100 quality.

  • Strange message during the Linux boot and slow start caused by "udevd[336] timeout ... "

  • MySQL query very slow on Amazon RDS but really fast on my laptop?

    - by Luc
    I would love to know if anybody knows why this is happening. i've just migrated over to Amazon RDS for our website and our biggest query which takes .2 seconds to execute on my macbook takes 1.3 seconds to execute on the most expensive RDS instance. Obviously i've disabled query cache (and tested this) on my local computer and both databases are exactly the same. InnoDB, both have the same indexes etc. It's costing us a fortune ($2000 per month) for the fastest RDS instance and i'm losing faith quickly. any ideas?

However, when ever I move a window, the redraw of that window takes 3-8 seconds. Even moving the window takes the same amount of time Is this being done in software rather than the nVidea hardware? The windows themselves do not respond. I have seen a few old threads but no relevant fixes - If anyone could suggest a fix I would very much appreciate it. Thanks in advance
