• MySQL Memory Limit Windows Server 2003

  - by Matt

  I am running MySQL 5.0.51a on Windows Server 2003 Standard Edition on an HP DL580 G4 with 3GB installed. One of my database tables has grown to 5.3 GB with an index file of 2.5 GB, which I believe is causing MySQL to be slow due to having to constantly load and unload the index file when updates are made to the table. The server itself seems to be performing OK because MySQL is only using about 500MB of memory (there are other apps running on the system, but MySQL uses the most memory). The table is fairly active with new records getting adding all during day but no deletes, ever. The MySQL server has up to 600 connections allowed, but only small number (10 or 20) would actually be writing to this table. I increased the memory limits in MySQL but since the max connections is so high I don't think I can give each connection 1GB without risking a problem. Is there some tuning that would let just certain connections get a lot of memory? So I have started to look for alternatives to avert the crisis I know is coming soon. Some of the options I have: Upgrade to Server 2003 Enterprise to install 64GB of memory. Question: would 32 bit MySQL be able to access more than 2GB? Would that be 2GB per thread? That would still be smaller than the index table size so it might not solve the problem completely, but it would be better than now. Upgrade to Server 200x 64 bit and MySQL 64 bit. Switch to a *nix 64 bit server. If anybody has suggestions for things to do in the meantime, opinions on which way to go, or other things that I have overlooked I would appreciate the help. Thanks

• Opera's problem with magnet-links

  - by Dmitriy Matveev

  I've encountered following problem while using Opera web browser: When I click on a magnet link on some web page like magnet:?xt=urn:tree:tiger:CXW6MJFRNOEFU2STCBWWOIYZLVCR2FTR37SQCXY&xl=352342016&dn=ER%20-%207x16%20-%20Witch%20Hunt.avi Opera is asking me if I want to open that link with my DC++ client. If I click 'Yes' button then my DC++ client is correctly "opening" the clicked magnet link and performing some action on it. There is also an option "Do not show this dialog again" in Opera's dialog, but it doesn't seem to be working correctly. If I check that option before answering 'Yes' and then click on other magnet link of the same kind the Opera will again ask me about how to open new link. I haven't found protocol association in 'Control Panel Default Programs Set Associations' part of my Windows Vista settings, but if I paste magnet link in "Run" dialog then Vista will handle that link perfectly. I've tried to find out how to manually set protocol association in Opera and found 'Programs' page of browser's advanced settings. There I discovered that instead of storing protocol to application associations Opera tries to store per-link associations (There are several entries with exact links as they was on web page as value of protocol field). If I click on the links which are already stored in Opera's protocols associations browser will ask me about them again. I haven't found any information on how to resolve this problem on the internet, maybe someone on this site will be able to help me.

• In Windows 7 power management, is it possible to set different sleep settings for different SATA disks?

  - by Ben Voigt

  I'm having an issue with Windows 7 either freezing up or generating a BSOD coming out of sleep. I suspect that it is related to my boot/OS drive, an OCZ Vertex SE SSD, because numerous other Vertex users have reported sleep problems. Notably, if I put the computer to sleep, it almost always wakes correctly. If it goes to sleep after a timeout, it almost always BSODs. I disabled timed sleep and now it freezes when left unattended. My next step is to disable "Put hard disks to sleep after X minutes", but I'd like to change this setting only for the SSD and not for the rotating data disks, which I would like to spin down normally. Does anyone know a place to configure sleep on a per-disk basis? I don't need to set different timeouts on different disks (although that would be nice), simply setting "this disk sleeps" and "sleep is disabled for this disk" would be great. Additional system information: Windows 7 Ultimate x64, Core i5 - P55 chipset, Intel RST drivers are installed. One SSD, two rotating HDD, and a DVD-RW drive are all connected to the Intel SATA ports. I could potentially move some of these to my motherboard's other SATA controller if that would help.

• Server 2008 RAID 5 Write Speeds

  - by Solipsism

  I recently configured a RAID 5 partition in Server 2008 with 4 RAID 5 disks. These disks are connected through a SATA expansion card that uses PCIe. This morning, I checked and they had finally finished synchronizing, and so I tried to do some speed tests. Copying off the disks started pretty much fine - speeds began at 125MB/s, then trailed down to about 70MB/s, which I found odd but not worrying. Writing TO the disks however is a completely different story. I attempted to copy some of my VM host ISOs onto the disks (~2-4 GB apiece) and this resulted in speeds of approximately 10MB/s. I tried copying both from a local disk (connected directly to the motherboard) and from another server ththe gigabit network and results were the same. I checked the performance monitor while transferring the files and the only thing that stuck out was that my memory hard faults shot up to 6,000 per minute (spiking around 200/s) by explorer.exe. The system is running 2GB of DDR667 ECC RAM and a quad-core 2.3GHz opteron. Is there anything I can do to fix this performance issue (buy more RAM? move the drives to a faster box?, etc) or am I just screwed so long as I stick to windows.

• Do background processes get a SIGHUP when logging off?

  - by Massimo

  This is a followup to this question. I've run some more tests; looks like it really doesn't matter if this is done at the physical console or via SSH, neither does this happen only with SCP; I also tested it with cat /dev/zero > /dev/null. The behaviour is exactly the same: Start a process in the background using & (or put it in background after it's started using CTRL-Z and bg); this is done without using nohup. Log off. Log on again. The process is still there, running happily, and is now a direct child of init. I can confirm both SCP and CAT quits immediately if sent a SIGHUP; I tested this using kill -HUP. So, it really looks like SIGHUP is not sent upon logoff, at least to background processes (can't test with a foreground one for obvious reasons). This happened to me initially with the service console of VMware ESX 3.5 (which is based on RedHat), but I was able to replicate it exactly on CentOS 5.4. The question is, again: shouldn't a SIGHUP be sent to processes, even if they're running in background, upon logging off? Why is this not happening? Edit I checked with strace, as per Kyle's answer. As I was expecting, the process doesn't get any signal when logging off from the shell where it was launched. This happens both when using the server's console and via SSH.

• Rendering a frame is producing noise from speakers in Windows and Linux

  - by Robber

  When any hardware accelerated application is rendering a frame (or many of them) a very short noise is coming from my speakers. This can be a game, a WebGL application or XBMC. When the application/game is rendering many frames per second (like most of them do) the noise is a continuous buzzing that gets higher pitched with higher framerates. This applies to Linux and Windows, so I'd assume it's a hardware problem. The current hardware in the PC is: CPU: Core2Quad Q9550 GPU: Radeon HD 5770 RAM: 2x2GB DDR2 Motherboard: Asus P5QLD PRO PSU: be quiet! Pure Power 530W Screen and speakers: Old 720p LCD TV connected via VGA and aux cable Muting the TV stops the noise, muting Windows doesn't. I tried replacing the PSU first (used a Tagan 700W PSU before) because I thought it was a power problem. It wasn't. I tried replacing the motherboard (used a ASUS P5B SE before) next because I thought it was a sound card problem. It wasn't. I tried the GPU in a different PC because I thought it was a broken graphics card. It worked perfectly fine in the other PC. I thought it might be interference, but moving the audio cable around changes absolutely nothing. I tried using an HDMI cable instead and that did work, but is not an option since my TV has only one HDMI input and I need that for my PS3.

• Load is 0, yet site crawls (sometimes). What gives?

  - by Yegor

  I have a ~1.5-2mil page views per day site running on 2 servers. One for mysql, other for everything else. Mysql box has a load of 3, frontend is usually 0.0-0.1. Both are dual quad core with 8GB ram running SAS drives in raid5. CPU is idle for majority of the time, iowait is non-existent. Im running nginx, memcache, and site is built on php. Half the time everything runs perfect, while at other times it lags something severe, when it takes 10-15 seconds for a page to load. Page execution time is always super low, but it seems to hang, waiting for something before it actually loads the page. Whats even more weird is that it only happens to 1 file on the site (but its the one thats most commonly accessed, that actually loads the content on the site). Other pages are super fast at all times, even when it takes 15 seconds to load actual content. I have nginx_stats plugin installed, and if I monitor it, the lag spikes happen when the write column starts going above 100, and it frequently does... all the way to 500-1000. It does so at totally random times... not when traffic is heavy... it can do this in the middle of the night, and work perfectly at 5pm when traffic is at its highest. Any ideas?

• sysbench memory test on ec2 small instance

  - by caribio

  I'm seeing a problem with sysbench memory test (the default version that's compiled in). This is on Ubuntu Maverick, sysbench installed via apt-get install sysbench. Running the same thing on Ubuntu @ Rackspace worked just as expected. While the CPU and I/O tests worked fine on EC2 servers, the memory test just runs without doing anything (notice the 0M in the test results). The instance used was the publicly available 'stock' Ubuntu image with no changes to it: ./ec2-run-instances ami-ccf405a5 --instance-type m1.small --region us-east-1 --key mykey Supplying more arguments (such as: --memory-block-size=1K --memory-total-size=102400M) didn't help.

I've tried removing the spns to no avail. Is there something I'm missing?

• Amavisd-new(2.6.4-3) failing to do "lookup_sql_dsn" when large number of emails are need to be accessed

  - by sandip

  Amavis is failing to do sql lookup when large number of emails are sent to amavis. Its throwing out error after scanning 40 to 50 email. It shows error like. (!!)TROUBLE in process_request: sql exec: err=7, 57P01,DBD::Pg::st bind_param failed:FATAL: terminating connection due to administrator command\nSSL connection has been closed unexpectedly at (eval 103) line 164, <GEN50> line 5. at (eval 104) line 280, <GEN50> line 5. As soon as this error appears in the logs, Amavis stops and port 10024 is closed. Thinking it to an error due to ssl connection in the database(postgresql-8.4), i had stopped ssl in postgres, but it was of no use. I have tried to configure amavis on another server, but i got the same error again. This happening on a production server, So i am not being able to scan emails as per user settings. Anybody have any idea, what may be the source of this error ?? Please help. Thanks in advance

• Looking for issue tracker software for residential property management

  - by Rob

  This question is about a computer software (as per SU guidelines) application for centrally tracking issues concerning the management of a residental block of flats (apartments as they say in the US and France). Issues are incidents - and their resultant unplanned maintenance to address them, also planned one-off maintenance and also regular planned routine maintenance. I live in a block of flats (apartments), and along with other residents, are looking to more closely watch over issues with the communal, shared areas of the premises (corridors, courtyards, stairs, lifts, lights, trash/bin shed, bike stands, parking areas etc) and their maintenance, currently done by a property management company. Our own homes are our own affair internally, its the outside communal areas that I have the interest. The aim being to control costs and possibly reduce them, by proactively managing the property using historical data to predict issues and also to scrutinise maintenance charges against such data to ensure that the costs are as expected. Trending could also be established whereby recurrences of things can be detected and pre-empted to reduce costs. As a software professional, I'm aware of Bugzilla, eventum being free tools for software - which could be customised to fit this application, but wondered if there was something more appropriate. It might be useful for such software to be on a web server, with secure access, so that residents can log in and view the issues.

• Large scale file replication with an option to "unsubscribe" from a replicated file on a given machine

  - by Alexander Gladysh

  I have a 100+ GB files per day incoming on one machine. (File size is arbitrary and can be adjusted as needed.) I have several other machines that do some work on these files. I need to reliably deliver each incoming file to the worker machines. A worker machine should be able to free its HDD from a file once it is done working with it. It is preferable that a file would be uploaded to the worker only once and then processed in place, and then deleted, without copying somewhere else — to minimize already high HDD load. (Worker itself requires quite a bit of bandwidth.) Please advise a solution that is not based on Java. None of existing replication solutions that I've seen can do the "free HDD from the file once processed" stuff — but maybe I'm missing something... A preferable solution should work with files (from the POV of our business logic code), not require the business logic to connect to some queue or other. (Internally the solution may use whatever technology it needs to — except Java.)

• 150 TB and growing, but how to grow?

  - by seandavi

  My group currently has two largish storage servers, both NAS running debian linux. The first is an all-in-one 24-disk (SATA) server that is several years old. We have two hardware RAIDS set up on it with LVM over those. The second server is 64 disks divided over 4 enclosures, each a hardware RAID 6, connected via external SAS. We use XFS with LVM over that to create 100TB useable storage. All of this works pretty well, but we are outgrowing these systems. Having build two such servers and still growing, we want to build something that allows us more flexibility in terms of future growth, backup options, that behaves better under disk failure (checking the larger filesystem can take a day or more), and can stand up in a heavily concurrent environment (think small computer cluster). We do not have system administration support, so we administer all of this ourselves (we are a genomics lab). So, what we seek is a relatively low-cost, acceptable performance storage solution that will allow future growth and flexible configuration (think ZFS with different pools having different operating characteristics). We are probably outside the realm of a single NAS. We have been thinking about a combination of ZFS (on openindiana, for example) or btrfs per server with glusterfs running on top of that if we do it ourselves. What we are weighing that against is simply biting the bullet and investing in Isilon or 3Par storage solutions. Any suggestions or experiences are appreciated.

• Exchange 2003 Internet Mail Size Limits

  - by scampbell

  I have unsuccessfully tried to increase per user incoming mail size settings by editing their user account settings on our Exchange server, but large incoming mail from external domains is still blocked using the default global settings. After reading here: http://support.microsoft.com/default.aspx?scid=kb;en-us;322679 I see that All Internet e-mail messages use the global setting for limits on sending and on receiving. The message categorizer evaluates the sender's sending limit and the recipient's receiving limit. In example 2 earlier, a user with a user mailbox limit of 3 MB could receive messages from another user with a 3-MB sending limit. Because Internet users use the global setting, they can send only a 2-MB message. Which to me is madness! Surely if I want to allow a user to receive mail up to a certain size then I should be able to set it as such? Is there a specific way of getting round this? Would setting the global defaults high and setting a lower, say 10MB, limit on the SMTP connector do the trick? Thanks.

• How do I get a network printer installed in ubuntu 9.04?

  - by SoaperGEM

  My girlfriend's work computer now has Linux on one of the partitions, and for the most part it's running fine--except that I can't seem to get the network printers configured right. There are two of them: a Lanier MP 7500/LD275 and a Lanier MP C3000/LD430c, and Linux seems to have found them both automatically. I'll go through the steps of what I did, and what exactly went wrong. I went to Administration Printing, and clicked the new printer button. It searched for printers and found them both, listed under "Network Printers." I added them as new printers in succession. However, when I clicked "Print a Test Page," it failed saying there was a broken pipe. The device URIs were saved as socket://[ip address]:9100. I changed these to lpd://[ip address] per some online tutorial, which at first looked like it might have worked (but didn't). Then when I tried to print a test page, it first said Processing (and sometimes even Processing - printing test page, 4%, but always subsequently displays Idle - /usr/lib/cups/backend/lpd failed. Help! What do I do? It seems like Linux can find these printers just fine, and the drivers seem to be in place, so what's going wrong?

• Siege - running a stress test benchmark

  - by morgoth84

  I need to do a benchmark test of a HTTPS server using Siege, to see how it behaves under massive load. I'm initiating tests from another machine which is quite powerful and it is connected to the same physical switch the server is connected on. But when I initiate a test, I can't get it to make more than 170 requests per second. With this load the server's CPU usage is at 15-20% and the average response time for a request is approx. 0.03 seconds. Load of the client machine is approx. at 10%. So, I gradually increase the number of users in Siege (the number of worker threads) and request rate linearly increases up to 170 reqs/sec, but it never gets over it. No matter how many more worker threads I start, the load on the server is never more than 20% (and the client's load also doesn't increase any more). How can I overcome this? I've googled a bit and found out that after a request is completed, a socket associated with one ephermal port remains in WAIT_TIME state for some time during which it can't be reused. I tried to overcome this by doing these things: sysctl -w net.ipv4.ip_local_port_range="1024 65535" echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle Oh, and the client machine is a Linux (RedHat, I think, but I'm not sure). Any help would be appreciated.

• What to do with old laptop screens?

  - by Lord Torgamus

  This question is inspired by another SU question I came across earlier today: What to do with old hard drives? It made me think about two long-dead laptops I have with perfectly good screens still inside. One is a Dell Inspiron 5100 and the other is an Averatec E1200, but responses need not be geared towards those particular models' screens. Rules, based heavily on the original question's: Objectives and suggestions to keep in mind when you post an answer : Should showcase your geekiness, be plain ol' fun, serve a social purpose or benefit the community. Your answer need not be limited to only one screen. For a really good answer, I'll go out and buy additional leftover screens. Your answer need not be limited to one project per screen. If additional accessories need be purchased, make sure they are common. Don't tell me to get a moon rock or something. The projects you suggested should serve a useful purpose; art is nice, but functional art is way better. Thanks in advance, folks. EDIT: Found another related question. Fun projects to do with an old 17" LCD monitor EDIT 2: I, for one, am enjoying the new outpouring of creativity here. Best fifty bucks... I mean, rep points... I ever spent. EDIT 3: That does it. At the end of the week, there was a tie for most votes between the accepted answer and the game platform answer. The game platform answer was cooler, but less reasonable as a project to actually do; in other words, it was more moon rocky. Unfortunately, I think fencepost had the best comment on the topic, which is that displays on their own have no good interface. Thanks for playing, everyone!

• nginx with fail2ban and mod_security

  - by Mahesh

  I forgot to update my fail2ban config for nginx. I just moved to nginx from apache. Today, I got a lot of cals from a single IP. IP tried to access login pages with post and get methods IP tried to use nginx as a proxy (GET http:/...) IP searched images, js, css folders IP tried to inject -d url_allow_fopen =1 and something similar. Most of the calls ended with 404. http { limit_req_zone $binary_remote_addr zone=app:10m rate=5r/s; ... server { ... location / { limit_req zone=app burst=50; } I got approximately 50 requests from that ip for a second. So i updated my nginx like the above. Will it avoid too many connections per second now? I have updated my fail2ban jail.local to support nginx. I am confused with the nginx-noscript.conf [Definition] failregex = ^<HOST> -.*GET.*(\.php|\.asp|\.exe|\.pl|\.cgi|\scgi) ignoreregex = I am serving php with nginx. I checked apache's noscript.conf and which has .php extension on it too. I tested this above settings before restarting fail2ban and got thousands of ips matched. I removed php and nothing matched. Do i need .php| in nginx-noscript.conf? Using mod_security and fail2ban together bring any problem? When i was searching today, i came to know mod_security is available for nginx too. So i am planning to use it too.

• Fill down in Excel, but based on multiple values

  - by Jenn D.

  I have spreadsheets (not created by me) that have blank entries in one column where they should really have data. I want to take every empty cell and fill it with the nearest value above it. I'm looking for as little manual intervention as possible, because I'll have to do it repeatedly. I thought some previous version of Excel, or maybe another spreadsheet from the distant past, would do this by default -- that is, if you selected the column with foo and bar, and chose the equivalent of "fill down", you would get what's in the WANT column. What I actually get in Excel is the GET column. HAVE: WANT: GET: foo 1 foo 1 foo 1 2 foo 2 foo 2 bar 1 bar 1 foo 1 2 bar 2 foo 2 3 bar 3 foo 3 I'm worried that this might need a macro to be done properly. I used to be a whiz with Excel macros, and then suddenly they were all in VB. My fallback position will be to dump the whole thing to CSV and write a Python script, but if there's any way to do it in Excel that would be much preferable. Even if it involves a couple of different manual steps, that's fine; just not one step per group of lines. That is, a process of "copy the column, do X to it, cut and paste it back" would work, but "do X for each occurrence of foo or bar" won't. The files are too big for that. Any thoughts are appreciated!

• Ways to parse NCSA combined based log files

  - by Kyle

  I've done a bit of site: searching with Google on Server Fault, Super User and Stack Overflow. I also checked non site specific results and and didn't really see a question like this, so here goes... I did spot this question, related to grep and awk which has some great knowledge but I don't feel the text qualification challenge was addressed. This question also broadens the scope to any platform and any program. I've got squid or apache logs based on the NCSA combined format. When I say based, meaning the first n col's in the file are per NCSA combined standards, there might be more col's with custom stuff. Here is an example line from a squid combined log: 1.1.1.1 - - [11/Dec/2010:03:41:46 -0500] "GET http://yourdomain.com:8080/en/some-page.html HTTP/1.1" 200 2142 "-" "Mozilla/5.0 (Windows; U; Windows NT 6.1; C) AppleWebKit/532.4 (KHTML, like Gecko)" TCP_MEM_HIT:NONE I'd like to be able to parse n logs and output specific columns, for sorting, counting, finding unique values etc The main challenge and what makes it a little tricky and also why I feel this question hasn't yet been asked or answered, is the text qualification conundrum. When I spotted asql from the grep/awk question, I was very excited but then realised that it didn't support combined out of the box, something I'll look at extending I guess. Looking forward to answers, and learning new stuff! Answers doesn't have to be limited to platform or program/language. For the context of this question, the platforms I use the most are Linux or OSX. Cheers

• Slower/cached Linux file system required

  - by Chopper3

  I know it sounds odd but I need a slower or cached filesystem. I have a lot of firewalls that are syslog'ing their data to a pair of Linux VMs which write these files to their 'local' (actually FC SAN attached) ext3-formatted disks and also forward the messages to our Splunk servers. The problem is that the syslog server is writing these syslog messages as hundreds, sometimes thousands, of tiny ~4k writes per second back to our FC SAN - which can handle this workload right now but our FW traffic's going to be growing by at least a factor of 5000% (really) in coming months and that'll be a pain for the SAN, I want to fix the root cause before it's a problem. So I need some help figuring out a way of getting these writes cached or held-off in some way from the 'physical' disks so that the VMs fire off larger, but less frequent, writes - there's no way of avoiding these writes but there's no need for it to do so many tiny ones. I've looked at the various ext3 options, setting noatime and nodiratime but that's not made much of a dent in the problem. Obviously I'm investigating other file systems but thought I'd throw this out in case others have the same problem in the future. Oh and I can't just forward these messages to Splunk, our firewall team insist they're in their original format for diag purposes.

• Pulling application updates from closest server?

  - by Mike Morris

  Setup: 6 Major Sites with Server 2003/2008 DCs doing DHCP/AD Integrated DNS, each on their own subnet. All connect back to datacenter through a 3 mbps WAN ERP server running in the datacenter, accessed by clients at all sites Currently, when we update the software, I manually push a copy of the updated client/config files down to each DC. I have a script that we run on each PC to update the clients. It determines what subnet the PC is on, and pulls the software from that DC. It's messy, but it works. The client has an autoupdate feature, but it'll only pull from the application server (which is housed in the datacenter, over the 3 meg link). It takes forever, since the updates are not "patches" but a full version of the client, even for minor upgrades (bad design). After the most recent patch, you can configure the clients to pull from a different server. Unfortunately, it is the same for all clients. Is there some kind of DNS magic I can use to pull from the local server? For instance, if I tell the clients their update server is ERPUPDATE, can I have their local DNS server return a different IP for ERPUPDATE than the other sites? Example: Client 1 is at site A, client 2 is at site b. They each run the software and a version change is detected. As per the config files, the clients look to ERPUPDATE for their updated client. Client 1 queries DNS for the IP of ERPUPDATE at its current location (site A) DNS at site A returns 192.1.1.5 Client 1 pulls update from 192.1.1.5 Client 2 queries DNS for the IP of ERPUPDATE at its current location (site B) DNS at site B returns 192.1.2.5 Client 2 pulls update from 192.1.2.5 Excuse the poor explanation, I worked 61 hours over the weekend and haven't completely rebounded. I'll be happy to clarify if needed!

• Possible disk IO issue

  - by Tim Meers

  I've been trying to really figure out what my IOPS are on my DB server array and see if it's just too much. The array is four 72.6gb 15k rpm drives in RAID 5. To calculate IOPS for RAID 5 the following formula is used: (reads + (4 * Writes)) / Number of disks = total IOPS. The formula is from MSDN. I also want to calculate the Avg Queue Length but I'm not sure where they are getting the formula from, but i think it reads on that page as avg que length/number of disks = actual queue. To populate that formula I used the perfmon to gather the needed information. I came up with this, under normal production load: (873.982 + (4 * 28.999)) / 4 = 247.495. Also the disk queue lengh of 14.454/4 = 3.614. So to the question, am I wrong in thinking this array has a very high disk IO? Edit I got the chance to review it again this morning under normal/high load. This time with even bigger numbers and IOPS in excess of 600 for about 5 minutes then it died down again. But I also took a look at the Avg sec/Transfer, %Disk Time, and %Idle Time. These number were taken when the reads/writes per sec were only 332.997/17.999 respectively. %Disk Time: 219.436 %Idle Time: 0.300 Avg Disk Queue Length: 2.194 Avg Disk sec/Transfer: 0.006 Pages/sec: 2927.802 % Processor Time: 21.877 Edit (again) Looks like I have that issue solved. Thanks for the help. Also for a pretty slick parser I found this: http://pal.codeplex.com/ It works pretty well for breaking down the data into something usable.

• tomcat vs FULL J2EE Solutions

  - by jrhickey

  We are getting ready to make a major revision in our Web Application architecture which currently is running on JBoss 4.2. At first we were looking at moving from 4.2 to JBoss 6 but after some research tomcat may be a better solution for us. My first question is their anything that JBoss can do that tomcat cannot do assuming you are using the correct plugins. We do not really use EJB's in our solution and it would appear there are simple plugins for web services, JMX and other features. Tomcat appears to have much better support, faster upgrade cycles and many, many books. Since there is less to the system it also seems much easier to support from an admin point of view. What am I missing? The main features we want to enable are better clustering support and session replication / persistence. We will consider other application servers as well such as Glassfish / Geronimo. quote form a web article: Apache Tomcat is the world’s most widely used web application server, with over one million downloads per month and over 70% penetration in the enterprise datacenter. Tomcat is used to power everything from simple one server sites to large enterprise networks.
