Need help with power supply.
My computer will not come on at all. When you hit the power switch on the power supply, all the fans in my computer begin to come on for a second but stops. Can someone help me. I 've tried 3 power supplies and none of them worked.

Need help with power supply & graphics card upgrades
I have a HP Pavilion p6320y that I bought 8 months ago. AMD Phenom II x4820 Quad Core processor. I play WoW and since the last big patch, have been suffering with low fps. I updated drivers and followed all the advice given to me by Blizz and finally figured out that my Nvidia GeForce 9100 (integrated graphics) isn't good enough anymore.
I checked my computer and discovered that I have a 300w power supply (12V) and read on another post here that something stronger than 300w is needed to run a decent graphics card.
Now for my questions:
How much of a power supply can I upgrade to without hurting my computer, but will be enough to run a good card?
What would be a good graphics card for this computer?
I've been looking at the Nvidia GeForce GTX 460 1GB GDDR5 PCI Express graphics card and wonder if that will work on my computer. Most of the nicer cards seem to be the PCI Express and I'm not sure if that will work.
Any advice will be most helpful. I have some experience with the inner workings of my PC and would like to fix this myself instead of running to the closest computer shop and paying someone else to. Thanks!
This question was solved.
View Solution.Well, you are starting out from a fairly low baseline with the integrated graphics. It will not cost much to have a substantial increase if all you want to do is run WoW without error messages. Yes, the 300w power supply is an issue and rules out any card that will require its own power (i.e. needs its own power cord like a hard drive) but there are several mid-grade cards that can run off bus power alone (i.e. just from the pci-e slot itself). Just taking a quick look at newegg.com I see the following:
GeForce 9400 under $50
Radeon HD 4650 under $50
GeForce 9500GT a little over $50
Any of these should get you where you want to be and not require a PS upgrade. The slot you have available is a PCI Express x16 slot so don't look at AGP cards; they will not work. If you want to install the card you mention you need to get a better PSU. -
Need Help with power supply reccomendations for my graphics card
hi
i have a MSI GeForce GTX 780 Graphics card... i built my own system, i also got a rosewill rx750 power supply in it which i think is causing me problems, the computer works great until i get into games like titan fall and try and get into a game then it restarts the computer on its own.. has done this with a few games, but it works fine when surfing the net and so forth, i have read its to do with the power supply being week and also read my chosen power supply isnt that good... anyone got any recommendations for me that i should look at or am i looking in the wrong direction with whats wrong with my pc... any help would be great thanksyes the PSU is the most important choice out there and corsair and seasonic are the best out there! (never buy cheap PSU's as like abvolt said a cheap one can easily kill your more expensive parts)
Cheap PSU = made of the most cheap parts they could get "think cheap shanghai parts are used that may be of any quality good or awful as its just what they could get for the lowest price" (ever bought anything that was super cheap they break very easily)
Quality PSU = the use of good quality well made parts and will have very good testing done on them to make sure they are stable and pass very tight regulations and conform to specs for 10-30 different factors each.
a cheap low quality PSU I class as a paper weight as it will never go near a computer (maybe i would use one as a basic bench PSU for things i do not care if they die or just for testing a fan or something that rubbish dirty power is not really a major problem but silicon is not tolerant to dirty power and will kill parts) -
Going to Australia and need help with Power converters
Facts:
US uses 110v on 60hz
Australia 220v on 50hz
Making sure I understood that correctly. Devices I plan on bringing that will use power are PS3 Slim, MacBook Pro 2008 model, and WD 1TB External HDD. My DS, and Cell are charging via USB to save trouble of other cables.
Ideas I've had or thought of:
1. Get a power converter for a US Powerstrip, and then plug in my US items into the strip and then the strip into an AUS Converter into Australian outlet. Not sure if this fixes the voltage/frequency change.
2. Get power converters for all my devices. But, not sure if my devices needs ways of lowering the voltage/increasing frequency or something to help with the adjustment.
3. Buy a universal powerstrip, which is extremely costly and I wouldn't be able to have here in time (I leave Thursday). Unless Best Buy carrys one.godzillafan868 wrote:

Check the specs on input voltage/frequency of your power supplies.
Many laptop power supplies are "universal/global" and are specced something like 80-265 volts AC 50/60 Hz, but not all. These will just need a connector adapter.
Unsure about the PS3 Slim - if it isn't universal it could be difficult as you'll need a 110/220 transformer, one big enough (power-handling wise) for the PS3 will be very bulky.
For the external WD HDD, if it doesn't have a universal supply, you're probably best off just finding a new wallwart for it that is capable of running on 220/50.

Hey guys!
here are my pc spec - well its old pc spec!
- i7 950 3.07Ghz
- msi x58m
- 1GB x 6 = 6 GB crucial ...
- HDD C: - WD raptor sata 2 150gb
- Club 3d ATI radeon HD 4890
- 3 extra hdd sata 2
- chieftec 3 bay HDD box for 4 extra sata2 HDD - I have 4 hdd there but they dont work all the time i turn them on only when i need it
- chieftec 750W ... aps-750c
now i did some changes!
i put my ATI card into my 2nd back up pc and updated the ram, so now i have :
- EVGA GTX 580 classified 3 GB
- 4GBx3 = 12GB corsair
1st two weeks all was fine, but now i CANT turn on my pc....... so in order to turn it on i disconnect the power cable, wait for some time then connect it again and if i try to turn it on right away it will not work , so after i connect the cable i wait for like 30 mins and then its strarts working...... after its turned on there are no problems, all working fine, but each time after i turn it off i just CANT turn it on, and have to make that "procedure" each time to turn on my pc!
now i took that chieftec 3 bay hdd box and put it on my back up pc, was hoping it will be better , but nope
is it really power? does the 750w really is not enough? any recomendations for a new power box?Your power supply might be a little marginal for the GTX 580. They require that the 12 volt supply be capable of 42 amps or 405 watts.probably the only way to check it would be to use an external voltmeter. Any chance you could return the GTX 580 and possibly go with a GTX 670? It only reqiures 30 amps. Here is what I found on the specs on the 12 volt rails
"The PSU is rated for an output power up to 550 watts and can yield up to 450 watts across its +12V rail. Thus, its effective output power (i.e. what you can get from it in a real computer that consumes mostly from the +12V power rail) is about 500 watts, which is good. The +12V rail is split into two “virtual” lines, 25 amperes each."
If the initial surge with everything turned on at once I would not feel comfortable with your system and that power supply. If I read you right you have three additional hard drives inside the unit. If you can disconnect the power to them for a quick test and turn on your computer you might isolate your problem. Typically each disk requires about 20 watts on startup -

Need help with clickbios ii terminolgy and values. Z77A-GD65 / 3770k
Hello All
I recently purchased a Z77A-GD65 board and after searching I've found the differences in terminology between this and my previous Asus board but still have a couple of settings I cant find any info on.
System Specs:
motherboard: msi z77a-gd65
cpu: intel 3770k
ram: corsair vengeance 2133mhz 1.5v
psu: corsair 850w
First things first is I believe I am running in turbo oc mode. I've selected the oc genie tab on the center right of the bios screen and proceeded to change settings there. With cpu voltage on auto and vdroop set to 50% at 4.6ghz. (I'll try and get screenshots of bios settings soon)
The following are the terms I need help with:
In the my oc genie section;
1. Long duration power limit
2. Long duration maintained
3. Short duration power limit
In the main overclocking section;
4. Digital Compensation level (not in owners manual, options auto/high)
5. Cpu core ocp expander (enabled for overclock 4.5ghz+?)
In the CPU Features section;
6. long duration power limit w (does "w" stand for watts?)
7. long duration maintained s (does "s" stand for seconds?)
8. short duration power limit
9. primary plane current limit a (does "a" stand for amps?)
10. secondary plane current limit
11. primary plane turbo power limit
12. secondary plane turbo power
I know those are a lot of settings, but would appreciate any simple definitions as to what they do and recommended values for mild overclocking (4.5-4.80)
Also on my previous board (Asus P8P67 Pro) my 3770k was stable in prime95 for 18 hrs at 4.5ghz fixed 1.155v with only ram timings put in manually and LLC set to extreme.(or whatever max is called in asus bios) Voltage was fixed and everything else was defailts.Well I'm back. Been digging around for a few days and found some answers to my questions.
First things first s that for some reason I could not adjust voltage values with the + or - symbols. Clearing cmos did not help this. I had to reflash the bios to get this functionality back as well as clearing cmos before and after the flash.
So I figured out the values in the oc genie section are the same as the normal section but only used when your using the oc genie. (numbers 1-3)
Digital compensation level and ocp expander should be set to high and enabled respectively when going for higher overclocks. (4 and 5)
Now for the rest of my questions ( 6 through 12) I have found suggested settings and some info after hours and hours of searching but still have a couple of questions about them.
Long/short duration power limit, and primary/secondary plane turbo limit. I see suggestion settings of 250 or 255. I take it this is simply max supplied watts to the chip? If so why the 250/255 values? Is that the highest the board will give? Is plane turbo limit related to the enhanced turbo stated and how much wattage can be drawn there while the other limit is for any non turbo frequencies?
Long duration maintained, I've seen 60 suggested a lot. Why is this?
There's not an over abundance of info on these boards as compared to asus so it seems info is a little less documented and video tutorials explaining things are next to none.
Any help would be appreciated. Thanks -
How to use the Camileo H30 with Power Supply
Hello
First: excuse my english, im from germany ;)
I have a Camilio H30. its was boughted used. I only got the camcorder & the original battery.
no extras (like usb cable or original power supply)
what i want: i need to film over some hours. The Battery cant make it. so i wanna use it with a power supply but when i put it in (throughh the mini usb a connector) the camcorder goes to charing mode (no actions are possible) but i want to use it fully functionality when power supply is connected.
how do i handle it ??
i got a power supply with 5V an 2,25A , i think its enough... or not??
The Label on the bottum side from the camcorder tells me 5V 2A....
Thanks 4 helping me :D
greetzoh ok i thought this is possible because in the main manual at the part when the display icons being explaind they show a full, half-full, emtpy- battery and a power connector icon. they call it "gleichstrommodus" sorry i have only the german manual. in english it should be co-corent flow mode or ac power mode.
im looking for a way to make the cam work with power supply only. i dont want to charge or even use the battery because i film over few hours ago and for that i dont need it.
my old dv cam works when the battery was plugged out with ac adapter only. thats very nice for me.
whatever. if this is not possible i sell this cam and buy another one ;)
thanks for your help ! -

Need help with a currently "in-use" form we want to switch to Adobes hosting service
Hi, I am in desperate need of help with some issues concerning several forms which we currently use a paid third party (not Adobe) to host and "re-distribute through email"...Somehow I got charged $14.95 for YOUR service, (signed up for a trial, but never used it)..and now I am paying for a year of use of the similar service which Adobe is in control of. I might want to port my form distribution through Adobe in the hopes of reducing the errors, problems and hassles my customers are experiencing when some of them push our "submit button". (and I guess I am familiar with these somewhat from reading what IS available in here, and I also know that, Adobe is working to alleviate some of these " submit" issues, so let's don't start by going backwards, here) I need solutions now for my issues or I can leave it as is, If Adobe's solution will be no better for my end users...
We used FormsCentral to code these forms and it works for the most part (if the end-user can co-operate, and thats iffy, sometimes), but I need help with how to make it go through your servers (and not the third party folks we use now), Not being cruel or racist here, but your over the phone "support techs" are about horrible & I cannot understand them or work with any of them, so I would definitely need someone who speaks English and can understand the nuances of programming these forms, to please contact me back. (Sorry, but both those attributes will be required to be able to help me, so, no "newbie-interns" or first week trainees are gonna cut it).... If you have anyone who fits the bill on those items and would be willing to help us, please contact me back at your earliest convenience. If we have to communicate here, I will do that & I can submit whatever we need to & to whoever we need to.
I need to get this right and working for the majority of my users and on any platform and OS.
You may certainly call me to talk about this, and I have given my number numerous times to your (expletive deleted) time wasting - recording message thingy. So, If it's not available look it up under [email protected]
(and you will probably get right to me, unlike my and I'm sure most other folks', "Adobe phone-in experiences")
Thank You,

Phenix City, Alabama 36869Well, thanks for writing back...just so you know...I started using Adobe products in 1987, ...yeah...back then...like Illustrator 1 & 9" B&W Macs ...John Warnock's Helvetica's....stuff like that...8.5 x 11 LaserWriters...all that good stuff...I still have some of it working on a mac...much of it was stuff I bought. some stuff I did not...I'm not a big fan of this "cloud" thing Adobe has foisted upon the creatives of the world...which I'm sure you can tell...but the functionality and usefulness of your software can not be disputed, so feel free to do whatever we will continue to pay for, ...I am very impressed with CC PS on the 64 bit PC and perhaps I will end up paying you the stipend that you demand for the other services.
So I guess that brings us to our problem.. a few years back and at the height of the recession and near bankruptcy myself, I was damn lucky and hit on something and began a small arts and crafts supply service to sell my products online to a very "niche market" ...I had a unique product and still sell that product (plus others) online...My website is www.vinylcouture.com...Strange? Yes...but there is a market it seems, for everything now, and this is the market I service...Catagorically, these are 99%+ women that use these "adhesive, sticky backed vinyl products" to make different "craft items" that are just way too various and numerous to go into... generally older women, women who are computer illiterate for the most part...and all this is irrelevant to my problem, but I want you to have every bit of background on this and especially the demographic we are dealing with, so we can get right to the meat of the problem.
OK...So about two years ago, I decided to offer a "plain sheet" product of a plain colored "stick back" vinyl... it is available in multiple quantities of packs ( like 5 pieces, 10 pieces, 15 pieces, in a packi & so on)...and if you are still on my site.. go to any "GO RIGHT TO OUR ORDER PAGE" button, scroll down a little...and then to the "PLAIN VINYL" section...you will see the Weebly website order process.) You can back out from here, I think,..but, anyway this product is available in 63 colors + or - a few. So then the problem is, how do they select their individual colors within that (whatever) pack?... .
So my initial idea was to enable a "selection form" for these "colors" that would be transmitted to me via email as 'part" of the "order process".. We tried getting our customers to submit a " a list" ( something my competitiors still do, lol, poor bastards)......but that..is just unbelievable..I can't even begin to tell you what a freakin' nightmare that was...these people cannot even count to 10, much less any higher... figuring out what colors to list and send me... well, lets just say, it wasn't working......I had to figure out a better way...Something had to be done.
So after thinking this all out, and yeah...due to my total ignorance, i figured that we could make a form with Live Cycle Designer (Now Forms Central)...(back then something that was bundled with Adobe Acrobat Pro), I believe, and thats what this thing was authored in... and it would be all good...LOL!
Well not so simple...as you well know, Adobe Acrobat would NOT LET YOU EMAIL anything from itself.....it just wouldn't work (and I know why, and all that hooey), but not being one to take NO for answer,.I started looking for a way to make my little gizmo work.. So I found this company that said they can "hijack" (re-direct actually) the request to email, bypass the wah-wah, and re-transmit it to the proper parties.....for less than $100 a year, I think...its called http://pdf-fillableforms.com/.
A nice gentleman named Joseph Silva helped us program the thing to go to his servers and back out. Please dont hassle them...I need them...for now..it basically does work...try it...you should get back a copy of the form that you filled out...good luck however, if you're on MAC OSX or similar...
I have included a copy of both of our forms (and feel free to fill it out and play with it)...just put test somewhere on it...(and you must include YOUR email or it will balk)..they are supposed to be mostly identical, except one seems to be twice as large....generating a 1.7 meg file upon submission, while the other one only generates a 600K file or so...thats another issue for another day or maybe you can advise on that also...
OK so far so good......In our shop, once Grandma buys a 10 pack (or whatever), Only then she gets to the link on her receipt page ro the relevant "selection form" ,(this prevents "Filling and Sending" with "no order" and "no payment", another early problem we had)... which they can click on and it will usually download and open up on their device if all goes well...Then our little form is supposed to be fillable and is supposed to ADD UP all the quantities, so grandma knows how many she is buying and so forth right on the fly, and even while she changes her mind..., and IT'S LARGE so grandma can see it, and then it TOTALS it all up for them, ( cause remember, they can NOT add).., except there is a programming bug (mouse-click should be a mouse-up probably or something..) which makes you click in the blank spaces to get to a correct TOTAL...about 70-80% of our customers can enable all these features and usually the process completes without problems for them especially on PC's running Windows OS and Acrobat Reader X or XI...at least for most... Unfortunately it is still not the "seamless process" I would like or had envisioned for the other folks out there that do have trouble using our form.... Many folks report to us the following issues that we know of. First of all it takes too much time to load up...We know its HUGE...is there anyway that you can see, to streamline this thing? I would love for it to be more compact...this really helps on the phones and pads as I'm sure you well know.
Some just tell us,"it WON'T work"....I believe this is because they are totally out of it and dont even have Adobe Reader on their machine, & don't know how to get it ( yes, we provide the links).....or it's some ancient version....no one can stop this one...
It almost always generates some kind ( at least one time) of "error message" which we do warn them about..., telling one, basically that "Acrobat doesnt even like this happening at all, and it could be detrimental to ones computer files", blah-blah...(this freaks grandma out really bad)...& usually they end up not even trying to send it... and then I get calls that even you wouldn't believe...& If they DO nut up and push the Red "Submit Form" button, it will usually send the thing to us (and also back to them at the "required email address" they furnished on the form, thats what the folks at the "fillable forms place" do) so, if it's performing it's functions, why it is having to complain?. What are we doing wrong?....and how can I fix it?...Will re-compiling it or saving it as a newer version of "FormsCentral" correct any of these problems ?
Ok, so that should keep you busy for a minute and we can start out with those problems...but the next thing is, how can I take advantage of YOUR re-direct & hosting services?, And will it get rid of the error messages, and the slowness, and the iOS incompatibilities ? (amazingly, the last iOS Reader version worked almost OK.. but the newest version doesnt seem to work with my form on my iphone4) If it will enable any version of the iOS to send my form correctly and more transparently, then it might be worth the money...$14.95 a MONTH you say. hmmmmm...Better be good.
Another problem is, that I really don't need 5000 forms a month submitted. I think its like 70-100 or less....Got any plans for that? Maybe I'm just not BIG ENOUGH to use Adobe's services, however in this case, I really don't care whose I do use as long as the product works most correctly for my customers as well as us. Like I said, If I'm doing the best I can, I won't change anything, and still use the other third party, If Adobe has a better solution, then i'm all for that as well. In the meantime, Thanks for any help you can provide on this...

I need to find the greatest grant year for the grant by a period parameter.
once i find the greatest year i need to check the value of period 14 for that grant for the previous year and add it to the budget amount for that grant. however if their is an entry in the greatest year for period 00 then i need to ignore the period 14 of previous year and do this calculation current period +(current period - greatest year 00)
hope that makes sense so in other words with the new data above. if i was querying period two of grant year 11. i would end up with $800
because the greatest year is 11 it contains a period 0 with amount of $400 so my total should be
period 2 amount $ 600
period 0 amount $ 400 - period 2 amount of $600 = 200
600+200 = $800
if i query period 1 of grant 360055 i would just end up with 800 of grnt year 10.
i have tried to modify that query you supplied to me with no luck. I have tried for several day but im embarrased to say i just can get it to do what im trying to do .
can you please help me out.
here is the query supplied by frank kulash who gracefully put this together for me.
WITH got_greatest_year AS
SELECT fgl.* -- or whatever columns are needed
, MAX ( CASE
WHEN fgl_period = :given_period
THEN fgl_grnt_year
END
) OVER () AS greatest_year
FROM fgl

FROM got_greatest_year
WHERE ( fgl_grnt_year = greatest_year
AND fgl_period = :given_period
OR ( fgl_grnt_year = greatest_year - 1
AND fgl_period = 14
;MiguelHi, Miguel,
Are you waying that, when the greatest year that has :given_period also has period='00' (or '0', or whatever you want to use), then you want to double the budget from the given_period (as well as subtract the budget from the '00', and not count the pevious year's '14')? If so, add another condition to the CASE statement which decides what you're SUMming:
WITH got_greatest_year AS
SELECT TO_NUMBER (fgl_grnt_year) AS grnt_year
, fgl_period
, TO_NUMBER (fgl_budget) AS budget
, MAX ( CASE
WHEN fgl_period = :given_period
THEN TO_NUMBER (fgl_grnt_year)
END
) OVER () AS greatest_year
FROM fgl
, got_cnt_00 AS
SELECT grnt_year
, fgl_period
, budget
, greatest_year
, COUNT ( CASE
WHEN grnt_year = greatest_year
AND fgl_period = '00'
THEN 1
END
) OVER () AS cnt_00
FROM got_greatest_year
SELECT SUM ( CASE
WHEN grnt_year = greatest_year -- New
AND fgl_period = :given_period -- New
AND cnt_00 > 0 THEN budget * 2 -- New
WHEN grnt_year = greatest_year

Need help with upgrading my OS from 10.5.8
Need help with upgrading my OS. I havent upgraded the OS since I bought it and have version 10.5.8. Now I cant download Mountain Lion- or even Snow Leopard. When i downloaded the first version of SL- 10.6.1 it says i have to have 10.6 first and I cant find that.
Start by checking if you can run Snow Leopard:
Requirements for OS X 10.6 'Snow Leopard'
http://support.apple.com/kb/SP575
Whilst Apple withdrew Snow Leopard from their stores, you can still get it from Apple by calling 1-800-MY-APPLE (if you are in the USA) and they will supply the SL DVD for $20 for a single user, or $30 for a family pack that covers up to 5 Macs. You can also purchase the code to use to download Lion from the same number (Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, running the latest version of Snow Leopard), or you can purchase Mountain Lion from the App Store - if you can run that:
http://www.apple.com/osx/specs/
If you are outside the US call your national Apple Helpline:
http://support.apple.com/kb/HE57
If you're in the UK, use this number: 0871 508 4400
When you have installed it, run Software Update to download and install the latest updates for Snow Leopard.
UPDATE:
OS 10.6 Snow Leopard is once again available from the Apple Store:
http://store.apple.com/us/product/MC573/mac-os-x-106-snow-leopard
and in the UK:
http://store.apple.com/uk/product/MC573/mac-os-x-106-snow-leopard
but nobody knows for how long it will be available.
To use iCloud you have to upgrade all the way to Mountain Lion:

Need help with Berkeley XML DB Performance
We need help with maximizing performance of our use of Berkeley XML DB. I am filling most of the 29 part question as listed by Oracle's BDB team.
Berkeley DB XML Performance Questionnaire
1. Describe the Performance area that you are measuring? What is the
current performance? What are your performance goals you hope to
achieve?
We are measuring the performance while loading a document during
web application startup. It is currently taking 10-12 seconds when
only one user is on the system. We are trying to do some testing to
get the load time when several users are on the system.
We would like the load time to be 5 seconds or less.
2. What Berkeley DB XML Version? Any optional configuration flags
specified? Are you running with any special patches? Please specify?
dbxml 2.4.13. No special patches.
3. What Berkeley DB Version? Any optional configuration flags
specified? Are you running with any special patches? Please Specify.
bdb 4.6.21. No special patches.
4. Processor name, speed and chipset?
Intel Xeon CPU 5150 2.66GHz
5. Operating System and Version?
Red Hat Enterprise Linux Relase 4 Update 6
6. Disk Drive Type and speed?
Don't have that information
7. File System Type? (such as EXT2, NTFS, Reiser)
EXT3
8. Physical Memory Available?
4GB
9. Are you using Replication (HA) with Berkeley DB XML? If so, please
describe the network you are using, and the number of Replica’s.
No
10. Are you using a Remote Filesystem (NFS) ? If so, for which
Berkeley DB XML/DB files?
No
11. What type of mutexes do you have configured? Did you specify
–with-mutex=? Specify what you find inn your config.log, search
for db_cv_mutex?
None. Did not specify -with-mutex during bdb compilation
12. Which API are you using (C++, Java, Perl, PHP, Python, other) ?
Which compiler and version?
Java 1.5
13. If you are using an Application Server or Web Server, please
provide the name and version?
Oracle Appication Server 10.1.3.4.0
14. Please provide your exact Environment Configuration Flags (include
anything specified in you DB_CONFIG file)
Default.
15. Please provide your Container Configuration Flags?
final EnvironmentConfig envConf = new EnvironmentConfig();
envConf.setAllowCreate(true); // If the environment does not
// exist, create it.
envConf.setInitializeCache(true); // Turn on the shared memory
// region.
envConf.setInitializeLocking(true); // Turn on the locking subsystem.
envConf.setInitializeLogging(true); // Turn on the logging subsystem.
envConf.setTransactional(true); // Turn on the transactional
// subsystem.
envConf.setLockDetectMode(LockDetectMode.MINWRITE);
envConf.setThreaded(true);
envConf.setErrorStream(System.err);
envConf.setCacheSize(1024*1024*64);
envConf.setMaxLockers(2000);
envConf.setMaxLocks(2000);
envConf.setMaxLockObjects(2000);
envConf.setTxnMaxActive(200);
envConf.setTxnWriteNoSync(true);
envConf.setMaxMutexes(40000);
16. How many XML Containers do you have? For each one please specify:
One.
1. The Container Configuration Flags
XmlContainerConfig xmlContainerConfig = new XmlContainerConfig();
xmlContainerConfig.setTransactional(true);
xmlContainerConfig.setIndexNodes(true);
xmlContainerConfig.setReadUncommitted(true);
2. How many documents?
Everytime the user logs in, the current xml document is loaded from
a oracle database table and put it in the Berkeley XML DB.
The documents get deleted from XML DB when the Oracle application
server container is stopped.
The number of documents should start with zero initially and it
will grow with every login.
3. What type (node or wholedoc)?
Node
4. Please indicate the minimum, maximum and average size of
documents?
The minimum is about 2MB and the maximum could 20MB. The average
mostly about 5MB.
5. Are you using document data? If so please describe how?
We are using document data only to save changes made
to the application data in a web application. The final save goes
to the relational database. Berkeley XML DB is just used to store
temporary data since going to the relational database for each change
will cause severe performance issues.
17. Please describe the shape of one of your typical documents? Please
do this by sending us a skeleton XML document.
Due to the sensitive nature of the data, I can provide XML schema instead.
18. What is the rate of document insertion/update required or
expected? Are you doing partial node updates (via XmlModify) or
replacing the document?
The document is inserted during user login. Any change made to the application
data grid or other data components gets saved in Berkeley DB. We also have
an automatic save every two minutes. The final save from the application
gets saved in a relational database.
19. What is the query rate required/expected?
Users will not be entering data rapidly. There will be lot of think time
before the users enter/modify data in the web application. This is a pilot
project but when we go live with this application, we will expect 25 users
at the same time.
20. XQuery -- supply some sample queries
1. Please provide the Query Plan
2. Are you using DBXML_INDEX_NODES?
Yes.
3. Display the indices you have defined for the specific query.
XmlIndexSpecification spec = container.getIndexSpecification();
// ids
spec.addIndex("", "id", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
spec.addIndex("", "idref", XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// index to cover AttributeValue/Description
spec.addIndex("", "Description", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_SUBSTRING, XmlValue.STRING);
// cover AttributeValue/@value
spec.addIndex("", "value", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// item attribute values
spec.addIndex("", "type", XmlIndexSpecification.PATH_EDGE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// default index
spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ELEMENT | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
spec.addDefaultIndex(XmlIndexSpecification.PATH_NODE | XmlIndexSpecification.NODE_ATTRIBUTE | XmlIndexSpecification.KEY_EQUALITY, XmlValue.STRING);
// save the spec to the container
XmlUpdateContext uc = xmlManager.createUpdateContext();
container.setIndexSpecification(spec, uc);
4. If this is a large query, please consider sending a smaller
query (and query plan) that demonstrates the problem.
21. Are you running with Transactions? If so please provide any
transactions flags you specify with any API calls.
Yes. READ_UNCOMMITED in some and READ_COMMITTED in other transactions.
22. If your application is transactional, are your log files stored on
the same disk as your containers/databases?
Yes.
23. Do you use AUTO_COMMIT?
No.
24. Please list any non-transactional operations performed?
No.
25. How many threads of control are running? How many threads in read
only mode? How many threads are updating?
We use Berkeley XML DB within the context of a struts web application.
Each user logged into the web application will be running a bdb transactoin
within the context of a struts action thread.
26. Please include a paragraph describing the performance measurements
you have made. Please specifically list any Berkeley DB operations
where the performance is currently insufficient.
We are clocking 10-12 seconds of loading a document from dbd when
five users are on the system.
getContainer().getDocument(documentName);
27. What performance level do you hope to achieve?
We would like to get less than 5 seconds when 25 users are on the system.
28. Please send us the output of the following db_stat utility commands
after your application has been running under "normal" load for some
period of time:
% db_stat -h database environment -c
% db_stat -h database environment -l
% db_stat -h database environment -m
% db_stat -h database environment -r
% db_stat -h database environment -t
(These commands require the db_stat utility access a shared database
environment. If your application has a private environment, please
remove the DB_PRIVATE flag used when the environment is created, so
you can obtain these measurements. If removing the DB_PRIVATE flag
is not possible, let us know and we can discuss alternatives with
you.)
If your application has periods of "good" and "bad" performance,
please run the above list of commands several times, during both
good and bad periods, and additionally specify the -Z flags (so
the output of each command isn't cumulative).
When possible, please run basic system performance reporting tools
during the time you are measuring the application's performance.
For example, on UNIX systems, the vmstat and iostat utilities are
good choices.
Will give this information soon.
29. Are there any other significant applications running on this
system? Are you using Berkeley DB outside of Berkeley DB XML?
Please describe the application?
No to the first two questions.
The web application is an online review of test questions. The users
login and then review the items one by one. The relational database
holds the data in xml. During application load, the application
retrieves the xml and then saves it to bdb. While the user
is making changes to the data in the application, it writes those
changes to bdb. Finally when the user hits the SAVE button, the data
gets saved to the relational database. We also have an automatic save
every two minues, which saves bdb xml data and saves it to relational
database.
Thanks,
Madhav
[email protected]Could it be that you simply do not have set up indexes to support your query? If so, you could do some basic testing using the dbxml shell:
milu@colinux:~/xpg > dbxml -h ~/dbenv
Joined existing environment
dbxml> setverbose 7 2
dbxml> open tv.dbxml
dbxml> listIndexes
dbxml> query { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }
dbxml> queryplan { collection()[//@date-tip]/*[@chID = ('ard','zdf')] (: example :) }Verbosity will make the engine display some (rather cryptic) information on index usage. I can't remember where the output is explained; my feeling is that "V(...)" means the index is being used (which is good), but that observation may not be accurate. Note that some details in the setVerbose command could differ, as I'm using 2.4.16 while you're using 2.4.13.
Also, take a look at the query plan. You can post it here and some people will be able to diagnose it.
