Optimal INI_TRANS value

I have a large table (300 million rows, 150GB in size) with many concurrent users update/insert/select for update nowait on it and I'm seeing several "ORA-00054: resource busy and acquire with NOWAIT specified" errors in the application logs. I have confirmed that the ORA-00054 errors were not caused by locking on the same records. I tried to increase the INI_TRANS value for this particular table to 10, up from 2, and the ORA-00054 erros went away. So I'm wondering is there a good way to make an educated guess on the optimal value of INI_TRANS for a particular table?

I appreciate the responses. Am i correct to say that ITL slots will take up space in the PCTFREE portion of a block or somewhere else? Is there a way to see the records that made up a particular block?
Shortage of INI_TRANS will indeed cause ORA-00054 error. The following is a test case to simulate the error:

INI_TRANS value and performance!!

Hi, all.
I am responsible for creating database objects of a production 2 node
RAC database(10.2.0.2.0). The block size is 8K.
The tablespace is locally managed and ASSM is enabled.
My question is :
1. Is it good to set ini_trans=1 of tables and index in terms of performance?
The size of one record is not so big.
2. Is there any negative effect if I set ini_trans=2??
Thanks and Regards.

Correction: Its not INI_TRANS; its INITRANS.
From documentation:
In general, you should not change the INITRANS value from its default.
Each transaction that updates a block requires a transaction entry in the block. The size of a transaction entry depends on your operating system. This parameter ensures that a minimum number of concurrent transactions can update the block and helps avoid the overhead of dynamically allocating a transaction entry.
The INITRANS parameter serves the same purpose in the statements that create and alter tables, partitions, clusters, indexes, materialized views, and materialized view logs.
1. INITRANS governs the number of "concurrent" transactions that can operate with rows in a particular block. So, if your block size is 8k and size of the records is very small, then you will have more number of rows per block. If application, via multiple users, keeps on looking for data in the same block, then you need to increase the INI_TRANS value.
2. INITRANS=2 should not be a negative effect since indexes, by default, are created with that value. You can specify a maximum of 255 concurrent transactions per block, however, that would eat up the block with header information itself.

Is there an optimal luminance value for LCD monitors

Hi you all,
I use Lacie 319 high end monitor as my primary monitor and "generic" Fujitsu as my secondary monitor (for PS tools etc.) I have calibrated the monitors with Spyder Elite 3, which also measures the ambient temperature of the room. Based on that measurement it suggests 140 cd for the white point (brightness) to calibrate the screen for. If you do this the prints printed with Epson 4900 (as well as with my previous Epson 4800) print far too dark. The colours are rendered for the printer with Image Print RIP (Colorbyte software). When I calibrate my monitor down to 80 cd the prints are quite OK although still a tiny bit too dark. My question is should I do the LR of PS optimisation of my pictures in the 140 cd monitor brightness and then reduce monitor brightness mechanically to the cd value which gives optimal brightness of the print (some 70 cd?) . Of course I have to adjust the brightness of the picture to be printed viasoft proofing. If continue doing as I do now making all my picture adjustments using a very low monitor brightness (ideal for the printed result) am I working in a less than optimal area for the monitor to deal with colors. Also do many of the folks in the internet see my pictures too light because they are using much brighter monitors than what I used to adjust the pictures.
Having asked the question I do know that many things affect on how you see or perceive the colors as well as the brightness of the print. So the answer is not that it depends on where you look your prints. I know the measured ambient light of my "lab" (was a photographer already in the time of film) suggests that I should use 140 cd as the brightness value of my monitor. Doing so produces prints far too dark when looked at the same ambient light. Using 80 (or 70 to be exact) cd monitor brightness gives good print results when the prints are looked in the same (as above) ambient light. My question is am I no adjusting my pictures too light for those using the "default" monitor brightness and is the color management of LCD monitors up to standard if you dial them as down as was customary for the big old CRTs.
yours Kari

General rule of thumb is:
80 - 90 cd/m2 for print
130 - 140 cd/m2 for screen
What I do:
Edit everything (print and screen) on a 80cd/m2 monitor. It works out very well.
Sounds like you're on the right track.

What is th optimal Database Buffer size?

Good evening SAP/Oracle experts,
I am interested to know how many of you have chosen to size your Oracle data buffer (db_cache_size). There seems to be two trains of thought about this
- one that says size the data buffer as large as you can because buffer accesses are 1000s of times quicker than disk accesses
- another that says that "excessive buffer visits are the morbid obesity of the database. Extra logical I/O can degrade the perfromance of virtually every subsystem in an Oracle application" (quote Cary Millsap)
As I tend to prefer the second argument, I originally sized the data buffer on our ECC5 Production system (with CI/DB running on a server with 8Gb RAM) at 500Mb. A few months after go-live, I increased the buffer to 750Mb and recently I increased it again to 1Gb. I found a slight performance improvement with each increase, but database time remained at around 50% of total response time (from ST03N) throughout. Our average response time is currently around 700-750ms, with database time around 300-400ms. Our database is currently around 450Gb.
I therefore ask you, the SDN community, to tell me how large you tend to size your data buffer in comparison to the total amount of RAM on your database server, and what % of your average response time is spent down at the database.
Thanks in advance for any help you can provide.

Dear Arwel.
To specify an optimal cache value, you can use the dynamic
DB_CACHE_ADVICE parameter with statistics gathering enabled to predict
behavior with different cache sizes through the V$DB_CACHE_ADVICE performance view.
When configuring a new instance, it is impossible to know the correct size for the buffer cache. Typically, a database administrator makes a first estimate for the cache size, then runs a representative workload on the instance and examines the relevant statistics to see whether the cache is under or over configured.
For more details about Sizing the Buffer Cache and Increasing Memory Allocated to the Buffer Cachelook at oracle documentation.
http://download-east.oracle.com/docs/cd/B10501_01/server.920/a96533/memory.htm#30301
In General Dont waste RAM use it completely but minimum 20% to OS and the rest to allocate.

Doubt between Original Traffic and Optimized Traffic

I have a question about the information displayed on the Traffic Summary Report.
Can any one explain to me how the Optimized Traffic value can be major than the Original Traffic value???
Thank you for assistance,
Diego

Diego,
From your stats, it definitely looks like you are running encrypted traffic through compression and DRE is adding the 5 byte signatures to all the packets going through the compression engine. Due to encryption, there is no repeating patterns in the payloads.
I would do the following...
1. Take the traffic and create a TFO only policy for it and add it to the top of your list so you are not wasting CPU cycles on attempting to perform compression.
2. Disable encryption/compression on the traffic you are targeting and let WAAS perform it's optimizations on it.
Hope that helps,
Dan

Combinations with Best Total value without Exceeding a maximum cost

Hello,
I have an interesting problem I am trying to solve and I am wondering if TSQL, or another tool like SSAS would be a good option for this. I am trying to find out the best performance from 8 parts while staying under a specific budget. Below is a generic
example:
I have to find the best combination of the following:
3 Part A
3 Part B
1 Part C
1 Part D(can be either A, B, or C)
The raw data that I will be using will look something like this:
Part # | Price   | Value | ID
A          | $22     | 44      |   1
A          | $21     | 42      |   2
B          | $20     | 41      |   3
C          | $18     | 37      |   4
B          | $17     | 35      |   5
B          | $2       | 1        |   200
I will have over 200 combinations of parts in total (some A, some B, some C).
In addition, I will have to find the best optimal total value for 100$ or less. It will be like Use it or Lose it 100$ so you want to be as close as possible without going over.
I am looking for something that can find out the optimal and rank it according to total value in a relatively quick amount of time. I know there are a lot of possibilities for this.
The end result will be something like this:
Total Value | Total Cost | A1 | A2 | A3 | B1 | B2 | B3 | C1 | D1
240           |   100        | 1 | 6 | 15 | 2 | 5 | 20 | 4 | 3
Let me know if you have any questions. Hopefully this makes some sense.

Output/Input Scale Factor

I have a high resolution stage used for a scanning application. I'm using a pci-7344 to control the stage. The system is marginally stable with kp=1 and various values set for ki and kd. I have found several posts with the same issue:

It is apparent that the gain needs to be set below one and the only current solutions (decrease encoder resolution or decreasing the output limits) are both unacceptable. Encoders aren't free (and in my case extremely difficult to replace) and I want my stage to run as fast as possible.
Many other modern controllers allow the input and/or the output of the PID loop to be scaled (even if it's only by factors of two for non floating point dsp's) for exactly this reason. This allows one to arbitrarily place the optimal kp value within the allowable integer range (i.e. 1<kp<32768). Is there a way to do this on ni controllers? If not is there a propper place to request features?

Unfortunately you can't scale the input or output of the PID loop. I am attaching two links below that discuss how to tune the servo motor and also where you can make product suggestions.

PLEASE HELP ME WITH DM PROBLEM

Hi Guys,
I kindly ask for your help with regards to my DM project. As you might recall, I am working on a project that is related to the field of agriculture and that has as an objective to find the "optimal values" of the operating conditions that affect the outcome (the amount of meat produced i.e. the weight) of an animal production (chicken broilers in my case). To do so, I have to use historical data of previous productions as my training dataset. The length a production cycle is typically around 44 days. For each production, a data acquisition system stores the real-time and historical data of hundreds of parameters. These parameters represent sensor measurements of all the operating conditions (current temperature, set point temperature, humidity, static pressure, etc...) and these are what I refer to as the inputs. The operating costs and the production outcome are what I refer to as outputs. The operating cost is indirectly computed from parameters like water consumption, feed consumption, heater/cooling runtimes, and lighting runtime; and the outcome of a production is defined by parameters like animal mortality and conversion factor (amount of feed in Lbs to produce 1Lb of meat). So the main objective of this project is to find the set of optimal daily values (1value/day) for the inputs that would minimize the operating costs and conversion ratio outputs.
The biggest problem I am facing right now is the following: The historical data that I have in the DB are time series for each measured parameter. Some of these time series follow some kind of cyclic pattern (e.g. daily water/feed consumption ) while others follow an increasing/decreasing trend (animal weight, total heater run time, total water/feed consumption..). My goal is to be able to come up with a model that suggests a set of curves for the optimal daily values throughout the length of the production cycle, one curve for each measured input/output parameter. This model would allow the farmer to closely monitor his production on a daily basis to make sure his production parameters follow the optimal curves suggested by my model. I have looked at ANN and I think it might be the solution to my problem since it allows to model multiple input/outputs problems (Am I wrong?), but I could not figure out a way to model the inputs/outputs as time series (an array of values for each parameter). As far as I know, all kinds of classifiers accept only single valued samples.
One approach would be to create one classifier/day (e.g. for day1: extract a single value for each parameter and use these values as a training sample and repeat this for all previous production to construct the training set). The problem with this approach is that 44 or so classifiers will be constructed (hard to manage all of this) and each of these resulting ANN will be some kind of typical average of the training data but not necessarily the optimal values leading to the best production outcome, if I am not mistaken.
Another approach would be to find a way to feed in the inputs and outputs as time series (an array of 44 daily values for each input/output parameter). In this case, there would be only one resulting ANN and the training samples, would be a set of arrays for each parameter, as opposed to single daily parameter values in the first case. The problem is, I could not find any classifier that would allow me to do that.
Another issue that I have is the amount of data. While a single production cycle could represent 1-2GB of data, the length of the production cycle (44 days) makes it difficult to have 100s of production cycle historical data, as I could gather data for no more than 7 full cycles/year. Fortunately, a farm can have many production units (5-10 barns/site in big sites), so this makes it possible to have 40-70 cycles/yr. My question is: would this be enough to come up with an acceptably accurate model or is it necessary to have hundreds of samples?
Thanks for taking the time to reading this lengthy post, and I really appreciate your help and thank you in advance.
Cheers.

Hi Guys,
I would really appreciate any help please. Maybe I was not precise enough
last time, so I am going to decribe things more clearly with examples.
Since the produced model will be used as part of an alarm/flagging
system, I will have to produce a curve of each of the parameters of
interest using 4 values/day=once/6h, and do this for the 44 days, this
is to flag and correct any abnormal behaviour ASAP. So, the whole
curve would have 4*44=176 values. E.g. for the water consumption
curve: day1: 12AM=65Gal, 6AM=150, 12PM ... DAY44=6PM=1500Gal. I would
have to come up with similar curves for each of the parameters of
interest (inputs/outputs). Now as far as ANNs are concerned, do I
have to produce 176 of these ANNs, one for each predicted value?
ANN1: input1 (temperature-value Day1@12AM) input2 (humidity-value
Day1@12AM)... output1 (feed consumption-value Day1@12AM), output2
(heater_runtime-values Day1@12AM)... and train the ANN with the 50-60
samples (Day1@12AM) from previous productions. This would produce an
ANN for predicting the value of each parameter for Day1@12AM for
future productions, etc.... This would quite intensive
computationally, so I am wondering if there is a better way to maybe
feed-in all the 176 values time series in one shot to have something
like input1(temperature-values 1-176), input2(humidity-values
1-176)... output1(feed consumption-values 1-176), output2 (heater
runtime-values 1-175)... and this will produce only one ANN which
will predict the 176 values for all parameters of future productions?
I would really appreciate your help as I am really stuck at this.
Cheers.

Svet's Care Package: Unlocked BIOS, vBIOS/EC tools, custom EC, ME update, etc.

ID: 27K920100T2026530
I have the MS-1763(-MFB1) barebone, and I would very much like a
"care package" of yours. My current setup is briefly listed in the BIOS
screen-shot, and I do not mind any updated versions of the firmwares
(BETA or ALPHA). If you need more details from my system, feel free to
list appropriate GNU-Linux/DOS tools and I'll give you their outputs.
Anyway, without further adiue, here's the list of what I have made
(if you got anything extra in mind feel free to mention that too
over PM ;3 )
- Fully unlocked BIOS (especially important that VT-d can be enabled*)
- Updated EC with optimized fan values
- Below 45C* the fan should be at minimum or off
- The fan should be at maximum when hitting 75*C
- Your vBIOS/EC tools. I got the GTX780M w/ 4GB
- Newest ME update if there is one.
I hope I'm not being to vague or confusing by this. If so I feel free to
help adjust my requests by PM. I hope the amount donated is sufficient
for you.
Thank you on beforehand; it's appreciated the work you do =)
*https://gist.github.com/anonymous/9106251 -- dmesg reports the BIOS as
broken, which possible means either there's a bug with IOMMU
implimentation or simply VT-d being disabled.

I newly installed Windows 7 onto my computer which till now I've used a GNU/Linux server, and I've come on a roadblock, that is the internal sound was disabled (and perhaps other things I as a end-user am not aware of), which works with the stock BIOS. Because of the lack of documentation I can't be sure to find what option that enables the sound device, and such I have a new request: the factory defaults of the old bios to be patched over to the new one or something in that direction so that what should be enabled by default, is.
Like last time, if there's any newer revisions of the firmwares (BIOS,EC,ME) I would not mind getting that patched up as well (same customization applies). And for your support, there might be another donation waiting for you in the end.
Thanks again Svet for your work. Hope to hear from you soon.

Dynamic_pager parameters

We're periodically getting "no space in available paging segments" errors on our Xserves (running 10.4.7). But we have 9G free on the root filesystem (where /var/vm resides) and there's never a system.log message about that filesystem running out of space. I noticed that it creates swap files that are 64M, 64M, 128M, 256M, 512M, and 1G, and
that's it. Looking at the comments in the source (ttp://darwinsource.opendarwin.org/Current/systemcmds-336.1.2/dynamic_pager.tproj/dynamicpager.c), it allocates files until it reaches one whose size is min(1/8 of the available free space, system memory, 1G) and that's it. 2G turns out not to be enough for us.
Anyway, I'm going to try directing dynamic_pager to use fixed-length files to see if that helps. I've arbitrarily chosen a size of 512M, high-watermark 128M, low-watermark 1.5G. Is there a way to empirically determine optimal
parameter values for each system? We don't want the root
filesystem to be full, but don't want the system to spend a lot of time allocating and deallocating and rearranging hundreds of MB on disk. I was hoping there's some profiling we could do.

[915 Series] No async PCIe clock possible

I have a 915P Neo 2 version 1.0A with latest bios 1.7
Bios offers the possibility to clock PCIe async.
Example:
FSB 200 shows PCIe of 100
FSB 240 shows PCIe of 114
But changing PCIe setting to anything else and the board does not boot. Only differences of 2 MHz to the optimal sync values are possible to let the system start.
Why is this a problem:
The onboard LAN does not operate at more than 116 PCIe clock and my grahics card does not run stable at more than 120 MHz PCIe clock.
Is there a solution available? Why won't the board boot with async PCIe clocks?
Thanks and regards

Yes, v1.6 should be able to support your CPU.

ColorChecker Passport-Color Profiles

Hi there,
I am photographing paintings with Elinchrom flashes with an even light and I use the ColorChecker Passport from X-Rite to keep a reference in order to match the colors.
Till now, I've been using the software DNG profile manager, provided with the ColorChecker Passport from X-Rite, which creates a camera profile that should be helpfull to get the right color. Once I've applied the new camera profile (after restarting lightroom), I do the white balance. It's recommended on the X-Rite tutorial to use the target number 20 called "neutral 8" to do the white balance. I've also tried the target 22 called "neutral 5", and it seems to get slightly better results.
I've noticed that even creating a color profile and doing the white balance the colors don't match. I am using a mac laptop screen that I calibrate quite often, which is not very helpful for obvious reasons, but that helps to keep track of the general look of the image, so that's why I keep the color adjustment to the RGB numbers.
I've downloaded the following PDF; here there is some information about the RGB values of various ColorChekers:
http://www.google.com/url?sa=t&source=web&cd=2&ved=0CB4QFjAB&url=http%3A%2F%2Fwww.babelcol or.com%2Fdownload%2FRGB%2520Coordinates%2520of%2520the%2520Macbeth%2520ColorChecker.pdf&rc t=j&q=ColorChecker%20rgb%20values&ei=wOCdTbG7NIyDhQelj5G8BA&usg=AFQjCNGj3wUpWC_uMxgMCeR3GI yN7kDU0A&sig2=mPf1grSAULxyMs_SanYVNw&cad=rja
Using these values and a selective color layer in photoshop I get close to the real colors, although it is not good enough.
My questions are:
1-Does anybody know the ColorChecker Passport RGB (Adobe 98) values?
2-I've tried to use the DNG profile editor because it seems a precise tool for this, but it doesn't recognise the 5D Mark II files. Is it because this application hasn't been updated? It also seems to work only with 6500K or 2850K, which is not the case of the Elincrhom 600 monoblocks I am using (which I think are around 5000K.
3-Could anybody recommend a workflow that's better to match the colors?
I have more questions, but I think these three are a good start.
Thanks!

Here are color-error analysis plots for several camera calibrations using the fine-art color-checker calibration shot uploaded, earlier.
The three profiles tested were:
1) A custom Elinchrom Flash profile I created from the color-checker using the DNG Profile Editor,
2) The Adobe Standard camera profile,
3) The custom profile provided by Gustov.
My general comment would be that the Adobe Standard profile has about the same error as the custom profile I computed using the DNG Profile Editor but the Adobe profile has a more even distribution of the color error.
The profile Gustov provided seems to be very close in the yellow area, but quite far off in the reds, blues, and violets. This can also be seen as a severe shift toward the green of the WB Tint slider value when the profile is selected for the As Shot WB as compared to the almost zero value when using the Adobe Standard profile.
These color-error plots were created using the ColorCheck module of Imatest Studio 3.7 from www.imatest.com. The program compares the measured color values from a color-checker image to the standard color numbers of the Color Checker then plots the difference on a CIE chromicity diagram, where the squares are the standard color position, the circles are the measured color position, and length of line in between is the color-error. In general, error in-and-out from the center is saturation error, while error around the center is hue error. In a 3D plot luminance error is also shown but harder to visualize without a way to rotate the plot around. Imatest provides this visualization in its Multicharts module.
I used the ProPhotoRGB colorspace when saving the TIF out of ACR because the standard ProPhotoRGB color-checker numbers in Imatest are for D50 lighting whereas the AdobeRGB standard numbers are for D65 lighting. As the image-filenames suggest, I used a linear toning curve and a black-point of 0 when saving out of ACR, but left the brightness at 50 and the contrast at 25. I tried zeroing out the brightness and contrast or using the Medium Contrast toning curve but things were way off. Using a blackpoint of 0 instead of the default of 5 also made things slightly better. There are scripts that can compute the optimal toning values for the gray patches but I was only comparing profiles, not trying to optimize them completely.

Photoshop CS6 color flow problem

Hey there!
I have returned once again to these forums because I seek help with Photoshop. I haven't used PS in a few months so it might be just me not remembering the correct settings OR a technical problem, but I seem to be having problem with color flow...
Here's what happens: Whenever I select a normal hard brush and try to paint with it the color flow stays the same and only becomes noticeable at around 20%, merely on the edges of the brush. On top of that the color values stay the same in the middle of the line I draw when flow is between 100% and 10%. I've tested and confirmed this with eyedropper tool.
However if I just click with the brush and don't drag it along the canvas the flow works just fine anywhere between 100% and 1%. Because of this it's impossible to mix colors on screen and shade artwork properly. I don't know if I need to check/uncheck certain settings, but I can't seem to find a reason why it's acting like this, nor can I fix this on my own. Could there be a problem with my tablet?
I really hope someone can help me with this. I've searched the internet for answers but couldn't find any so my last resort was to write on official Adobe forums. Thanks in advance for taking your time and reading my post.
Have a nice day!
Jerry
P.S. I've made a simple diagram to show you my problem and included it in an image below:

This worked in a way... I did exactly what you wrote, I changed the spacing to 100%(or more) and now the color flow is definitely noticeable no matter what it's value in % is, but my brush stroke turns into a series of connected dots.. I remember reducing the spacing from a default value of 25% to 1% on all of my brushes exactly because of this.
If I turn the spacing back down and below 100% to a more reasonable value the dots will start to overlap and the brush stroke will become smoother, but the color flow will become less and less visible as the % of the spacing decreases.
This is the solution I've come up with: In order to compensate for the visible overlapping at larger brush sizes AND keep the color flow functioning I increased the document resolution a few times and then pressed Control + 0 to fit the canvas on my screen. When you have a big canvas the large brush becomes much smaller and you can't really see the overlapping anymore, while still being able to maintain control of the flow of color.
But is that really the only way?
Also, what would you say is the optimal spacing value?

If you remove those lines, oracle has to again recalculate the optimal/efficient values for the dynamic memory segments managed by ASMM feature of Oracle10g. If you keep it as it is, oracle will have a starting point to rework or start from where it left off when the instance is restarted.

Question about Chroma Key Lights

Any kind of light for chroma key background will be alright?? I guess shopping to wal mart would be ok? Let me know.

ummmm, not likely.
You should have a VERY even spread of light across the chroma background, plus a good backlight to seperate your subject from the background as well as good front light on your subject.
Flourescent bulbs are great for even spread, but you should really try to get bulbs balanced for tunsten or daylight. There are filters/gels that can be used with consumer florescents, but even then you may get some tinting of your color spectrum.
Have you ever shot chroma? If you do not shoot it properly, you'll have nightmares in post.
You can place your lights above the camera line for talent, above the talent for chroma and above the chroma back at talent...(These can be more directional so you don't flare out your lens)
There are optimal lux values you should try to achieve, but I'll let others be more specific.
That said, I'll bet someone will chime in and tell how they did it with WalMart lights...I'm just offering a suggestion that might make it easier in post.
