In SAMS, low HWM & HWM

Hello

I can easily understand HWM in a segment of the MSSM.

But I don't understand the HWM and low HWM in a segment of the SAMS clearly.

Nobody has said, where the blocks before reaching low HWM are formatted and used.

And after high HWM, that areas (blocks) are not formatted and not used.

(Sorry, I don't know English well, so the expression above could be wrong...)

Please explain to me with a simple as example:

-When a segment is created first, where is the position of HWM low & high HWM

-When the first row is inserted

-When the next measurement is allocated

What is the area between low & high HWM, HWM.

Thanks in advance.

I refer to the quote from ASkTom once again,

In a tablespace MSSM, the segments have a certain HWM. In a tablespace SAMS, however, it is a HWM and a low HWM. MSSM, when the HWM is advanced (for example), all the blocks are formatted and validated, in Oracle can read them safely. With SAMS, however, when the HWM is advanced Oracle is not in shape all immediatelythey blocks are only formatted and secure to read from their first use. Thus, when it is full of a segment of digitization, we need to know if the blocks to be read are "safe" or not formatted (which means that they contain nothing of interest and we do not convert them). To ensure that not every block in the table must pass through this security safe/no check, Oracle maintains a low HWM and a HWM. Oracle will scan complete of the table until the HWM and for all the blocks below the HWM low, it will be just to read and process. The blocks between the low HWM and the HWM, to be more careful and consult information of bitmap SAMS for managing these blocks in order to see which of them should be read and that he should simply ignore.

Also check the link to docs,

http://docs.Oracle.com/CD/E11882_01/server.112/e40540/logical.htm#CNCPT89023

Please review both and we'll find out if you still have doubts.

  • Poor performance of Firefox after you apply the latest Microsoft Updates (Win 7 x 64); all solutions?

    Recently, I updated to Firefox 27 and noticed really horrible performance (Manager tasks indicates FF connecting a carrot, frequent "Firefox is not responding messages", even strikes in late development in the URL bar). It's on an Ideapad s205 (AMD E450 APU, Win 7 x 64, 8 GB RAM, SSD) who has always had pretty decent web browsing performance for a low end machine.

    At first, I blamed FF because poor performance coincided with the update to version 27, but now I think that the first cause to be a recent Microsoft Update. The reason is that my wife has a laptop with a same low-end APU (APU C60, hard drive 5400 RPM, 4 GB of RAM, Win 7 x 64), and she was getting much better performance with FF27 until I applied a backlog of some 90 + updates. Now she suffers from the same poor performance I am and she is pretty p * ssed at home.

    Interestingly, I have two WIn 7 x 64 Intel computers to office who have 27 FF and are fully patched, and performance are very good. Maybe this problem is specific to AMD APU.

    Any thoughts? I tried to turn off the backend Azure with some comments in this forum, but makes little or no difference.

    Thank you!

    Success! 32 FF seems to have solved my problems of performance. Thank you!

  • HP PHOTOSMART 7520E: HOW TO CONNECT THE 75 HP PRINTER TO THE COMPUTER AND THE ROUTER

    Here's my problem.  My modem from my ISP did not work properly and they brought a new modem and set up.  It is obviously not properly configured, and when I go on the computer I have to use the arrow in the lower right of my computer to connect to the Internet.  I also connect my printer using this same low right arrow.  My Internet provider tried to fix this error on the phone but IT does IS NOT WORKING CORRECTLY.  I call today for an appointment for a tech to come to my house to fix this.  That's why I can't take back my electronic impressions with crossword games, etc., until it is properly fixed.  I would ask BEFORE the tech comes to my home to BRING A MODEM it IS WORKING CORRECTLY.  When I spoke this morning with my Internet provider, I learned that there are other people in my neighborhood by using the same network, that's why I'm having this problem.  I TOLD THEM THAT I DO NOT ACCEPT THIS BECAUSE ALL THESE PROBLEMS HAVE OCCURRED AFTER THEY HAVE INSTALLED THIS OBVIOUSLY DEFECTIVE MODEM.  I HAVE THEM ALSO SAID SINCE I WAS 'SHARING' A MODEM WITH MY NEIGHBORS, I'LL ASK FOR A DISCOUNT ON MY SERVICE AND OF COURSE, THAT HAS NOT RECEIVED POSITIVELY.   I'll post an update when this problem is solved by my Internet provider.

  • WALKMAN NWZ-A726

    I got a NWZ-A726 for about 3 years now and have really enjoyed. I had to replace the headphones twice now. The last time was about 2 weeks ago. I replaced the with the same ones who came with them when I bought it new(MDR-EX082) both times. I also ordered a pair of headphones MDR-EX085 to compare the noise and as an extra pair. Now the problem is that the sound quality is not as good, with a pair, as it was before the old buds shorted. I even tried the buds of my wife and my daughter buds and all 4 sets of buds are the same. The bass is not deep at all, in fact, there is little agreement even bass. Then with the volume up when the sound level is trying to he started down. I tried to go back to factory settings and tried the reset button at the back where you will need to use a PIN to push. Has anyone else had this problem? I would just buy a new, but they are discontinued. I've been looking around but can't find one anywhere. Anyone who has ever used and compared with the new NWZ-S545? It has the same low sound quality like the NWZ-A726 older? If man is not an easy solution and the NWZ-S545 can give the same sound quality, I can simply get one of them.

    Thank you for your message.

    The NWZS545 is definitely a notch above your old Walkman NWZ-A726.

  • Satellite L500D slow downs

    This computer used to run fairly well (it is a dual core Athlon).

    Now, it is slow as a wet week.

    I disabled everything that can possibly be put off.

    I have same low leveled it for WinXP (from Win7)... on the assumption that it might be a piece of software that I couldn't find.

    It is still slow.

    Which makes me suspect that it's a hardware problem. The obvious risk culprit is the hard drive.

    So far, none of the tests I ran suggested that the player is running slowly.

    Anyone have any suggestions on how to diagnose or fix this slow down? Or did someone else having the same problem?

    :-)

    Hello

    What exactly do you mean by slow down?
    A race of demand slowly or load slowly?
    What is the freezing of the system or what is exactly happening?

    If you want to check the HARD drive, I recommend using a free tool called the HDD drive fitness test.
    Its nice tool and it allows you to get detailed information from fitness on your HARD drive.

  • Compac CQ58 fan runs constantly

    Hello.

    Six days ago, I bought a brand new Compac CQ58 and I noticed that the fan never stops running. The temperatures that I see on my screen for SpeedFan indicate fluctuations between 33 and 34 Celcius for HD1 and between 41 and 51 for Temp1, GPU and core.

    If the temperatures are not really high, but still maintaining fan running all the time, never stop.

    Is this normal? I don't have that with my previous laptop, a G62. Only things would turn out when the temperature could reach 50 C and turn off as soon as it was 40 ° C.

    Moreover, my G62 would go at different speeds depending on the situation. as during the startup, he'd be full for 10-20 seconds the screen has been re-appearance, while this one is same speed - not fast - all time non stop.

    Thank you.

    Until I found that in the BIOS 'Fan always on' mode has been set by default. I put it to see the difference on "Fan not always - it". The result was that temperatures have risen to fluctuate between 46 and 58 C.

    58 the fan running and go out again at 46.

    It was nice to have a complete silence for awhile in time, but when the fan turned on it still worked hard to audible, with the same low speed. Never, just like mode low speed varies "always on."

    I read further down the best for the life of the unit of temperature. And I guess a new fan would be less expensive than having a new GPU E1-1500 AMD E-Series set. So, I prefer to let the fan run on the mode "always on." It is in any case as hardly audible says.

    Again, the temperature of the GPU varies between 40 and 50 C.  in "always on". Ususally it is 40 C or a few degrees higher when the CPU is not very active.

    The "Temp1" and "basic" - as they are called by SpeedFan on my laptop - are essentially the same core sometimes making 39 c. low.

    I imagine that HP has made the decision to all BIOS on "Fan always - we" in Compaq CQ58 I have a good reason... it keeps the lower temperature to "not always - we", so I'll keep it in the middle.

  • How to install a second HDD in Stelllite P200D

    I want to install an SSD and move my HARD disk in the slot to the second HDD. I can't find any document how to install second HDD. Do I need special adapter or no matter what HW for this?
    best regards Frank

    Hello

    At the bottom of the unit, you will find two bays for HARD drives. Right?
    But a Bay does contain all the connectors? Right?

    At first glance, this might be a little strange, but the fact is that the different models of Satellite P200/P200D were available on the market with different motherboards.

    Some would argue a 2nd HARD drive but some don t units. But all models supports the same low coverage and some people think that a 2nd HARD drive would be possible, what's not.

  • Power Manager is suspended.

    Hello

    There is a ThinkPad Edge 15, which I've updated the BIOS system 1.21.

    I installed Power Manager for him and he hung around 5 times. Then I uninstalled it, and it does not crash again.

    I thought that maybe the problem is with the battery firmware, so I downloaded the firmware (and also the wrapper) and they both said: "There is no battery attached to the system in need of update of the firmware." or something like that.

    I thought perhaps that he needs, a battery meter, so I installed Power Manager again and the hanging started.

    I think the time it works on battery is too low, even for a battery 4 cells. He first said about 1 hour 45 minuets when it is loaded to 100%, then after 45 minutes (with the same low use, as in the beginning), it is said remainging of 45 minutes (of which a quarter is absent here.) and in the final minutes, it seems like running more than the estimate, he does now (every 2 minutes minute is decreesed of the estimate).

    Thanks in advance.

  • Decimation filter bandwidth

    Does anyone have information as to what the BW decimation filter is given at a certain rate of IQ?

    For my application, it is more important to vary/control the BW around the carrier.  It would be useful to know how 'work backwards' IQ rate since it is the variable that uses the driver.

    I'll assume the BW of rate and filter IQ have a fixed relationship regardless of the decimation factor, such as the relationship to the high rate of IQ (low decimation) is the same low IQ (strong decimation)?  Is there a "rule" calculation which could make me this info?

    For what it's worth, setting speed IQ doesn't seem to be a very useful setting. On the contrary, you are more likely to know the bandwidth you want to capture, and then let simply decimation would produce based on that.  Otherwise... If you're not careful (or don't know what you're doing) you might inadvertently filter/decimate and eventually a small piece of BW glancing you think... all this in the name of lower rates of data streaming of the USRP.

    The A/D NI with DDCS already seems to do.  You specify it given P.C. and SDC configures the decimation based on the nearest whole factor of the A/D sampling rate.  There is a handy little table in sheets which shows for a BW given, is that the IQ data resulting rate.  I'm basically looking for something similar for the USRP.

    Thank you!

    This could be a subtle understanding, I won RF by thet rate bu IQ equipment is ultimately limiting your maximum bandwidth. How much this bandwidth is usable depends on a device. (True for the acquisition and generation)

    In an ideal world, your IQ rate "would be tantamount to your bandwidth" (acquisition).  This is the general rule.  If you take a FFT on a number of samples at a rate of 10 MSa/s, you will find yourself with a frequency which extends MHz - 5 to + 5 MHz. If your signal uses this entire range of 10 MHz is not implied, but you would not be able to fully acquire a signal with a bandwidth greater than 10 MHz for sure.

    The USRP has specific IQ rates it supports, so I season always re-reading the IQ rate under duress.  If you need to change your filter specifications or need more flexibility just decimate and only filter process, think I woud suggest to implement a filter software - your choice opens considerably as well as being able to choose a butterworth on a chebyshev and specifying the order of the filter, etc..

    I also suggest reading this article as well from the GNU Radio page, it has a little more depth and background.
