• Question about the Log_Checkpoint_interval parameter

  What is the use for Log_Checkpoint_interval? Have an impact on the performance of DB?

  What kind of problems are you having?

  Take a look at this note:
  Adjustment of the control point and Troubleshooting Guide [ID 147468.1]

  ...
  LOG_CHECKPOINT_INTERVAL influences when a checkpoint occurs, which means
  careful attention should be given to the setting of this parameter, keeping it
  updated as the size of the redo log files is changed.  The checkpoint
  frequency is one of the factors which impacts the time required for the
  database to recover from an unexpected failure.  Longer intervals between
  checkpoints mean that if the system crashes, more time will be needed for the
  database to recover.  Shorter checkpoint intervals mean that the database will
  recover more quickly, at the expense of increased resource utilization during
  the checkpoint operation.

• Switching frequency of newspaper is very high

  Oracle 10g
  Sun Solaris
  
  I came across a situation where the newspaper switching frequency becomes very high for a couple of daily hours and then returns to normal.
  
  The increase in frequency occurs for about 6 to 8 hours daily. Then he is back to normal.
  
  
  It's a situation where we have to change the size of the recovery log?

  newlg1 wrote:
  Define 'normal '. Set 'top '.

  Just in the last hour, the log file switch happened on average 5 minutes.

  Not bad. For me the 'high' is a minute or less. For me 'normal' is 15-30 minutes.

  I tend to change the size of the usual load will cause a switch just about 15 minutes. Then, I'll use ARCHIVE_LAG_TARGET to keep roughly 30 minutes for no charge. You might have other values.

  There is also a checkpoint not complete messages in the alert log, but it was on
  On 18 April. I don't see that today.

  If the checkpoint is not complete is a regular show, try adding several groups of newspapers.

  However, both the size of the log and journal County should not be affected if you do not actually experience a problem. Still, what you describe is a symptom, not a problem in itself.

  >

  It is a RAC database. This log switch occurs in only one instance. But not the other.

  This is because the only case to charge more than others.

  If the load must be balanced, check your listeners and your TNS customer configurations. It is not uncommon set lots of hit one and a single node, which can be tuned. Yet once, controlled by network settings.

  Note that sizes of newspapers do not need to match each instance. Sizes are set according to the load expected on each node.

  In airport utility, go to the wireless tab... from options wireless at the bottom of this page and then you will see the wireless channels

  

  

  I put the 5 GHz channel because she was using a channel in Australia which is BAD.

  Personally, I doubt that this will fix your problem... It is more likely caused by too wireless signal around you and the TC as a poor place.

• Percentage of maximum CPU Windows 7 constantly frequency > 100%

  Under Windows, I find that my CPU fan runs constantly audible. The fan made ramp immediately after Windows starts, even with no applications running. Windows resource monitor shows the CPU usage in the range of 25 to 40%. However, the maximum percentage of CPU frequency is consistently above 100% (usually around 110-115%). This means that the system is too overclocking? If so, is it logical to deduce that this may cause the CPU fan to run so much? Finally, how can I get this back to 100% (or less)?

  The fan does not this way under MacOS.

• Frequency max RAM MacBook mid-2010 (7.1)

  Hello

  I wanted to update my MAC Book (mid-2010 - 7.1) with chip Ram 2 x 4 GB of Kingston. I got the last race of El Capitan, and even with just 2x2gb it actually works very well.

  I bought two Kingston KVR16LS11/4 - with 1600 MHz. The dealer told me that it will work with any MACBook.

  So I installed the two chips and nothing happens after that I press the Start button. ?!?!

  Do something wrong? The chips are not fair? I was wondering if maybe the frequency of chips is high priority - but I always thought, that the system it will operate at a lower frequency if necessary.

  Any chance of getting the chips running?

• absolute frequency

  Ho no problema con the frequenza, mi viene mostrata cumulativa invece che the assoluta. ad esempio 32 e 1 ed e corretto, mentre 33,34,35 deve essere 0 1 no che e del 32, cosi come 36 deve essere 2 e 3 (2 + 1). the formula che vedete e corretta?

  Hello, I have a problem with the frequency in my ipad. as you can see in the picture, I have the cumulative frequency, but I need absolute frequency. How can I do this?

  example:

  1/32 is: correct!

  East of 1/33, but he must show 0!

  36 is 3 (2 + 1 front), but he must show 2!

  the formula is correct?

  

  I suggest using the formula

  E4 = COUNTIF (ONE, D4)

  It's shorthand dethrone select cell E4, and type (or copy and paste it here) the formula:

  = COUNTIF (A, D4)

• HP 15-5000na omen: locks of CPU frequency to 0.80 GHz

  Hello

  My CPU get locks to 0.80 GHz and will not upwards or downwards. At the same time, when the CPU is locked to 0.80 GHz

  computers portable fans running fast (loud) but air to come is not yet hot.

  I found a tool called Extreme Intel (r) utility of tunning to use as monitor "which continues with my system."

  I'm not overclocking or change something in the CPU.

  Tunning utility indicates the value of the "thermal Throttling" 100%, I think that this is the reason why the CPU remains at 0.80 GHz to inhabit because of this thermal regulation.

  Package Themperature and core CPU is normal around 40 ° c.

  All this information is visible in this photo:

  This problem is to come and go at random, when the problem that is happening and I restart the laptop, I get the error from the BIOS says: Enter system (90 b) fan - keep booting

  With the random combination of restarts, stop, unplug the power and plug CPU gets frequency walk again

  Thermal regulation becomes zero and fans to stop... and everything is going normally.

  When the CPU's frequency stepping and normal works if I reboot the system BIOS displays messages: System (90 b) fan.

  This happens once or twice a day and it's very anoing... I'm losing a 15-20 minutes to restart the plug... and so on until the disappearance of the problem.

  I have the latest BIOS for my laptop and installed all updates for Windows 10.

  Software of HP Support assistant shows also no update available.

  Best regards, spetrov

  Hello

  Just to update, I returned my laptop for repair under warranty.

  Warranty card shows the replacement of the motherboard.

  After replacement, not stuck to 0.80 GHz CPU more.

• CPU runs at half the frequency in Satellite

  Not sure if it is a problem, but the CPU runs at half the frequency. I put the high performance plan and still the same. I think it should work at full power.

  I also tried to disable the CPU power option in the BIOS and nothing helped.
  To monitor the use CPU - Z and Speccy.

  What you think about this?
  Is it normal?

  Hello

  The Intel CPU supports the Intel Turbo Boost technology
  Dynamically, this Intel Turbo Boost technology increases the frequency of the processor as needed by taking advantage of thermal and power margin to give a burst of speed when you need it and increase energy efficiency when you don t.

  The CPU also supports Enhanced Intel SpeedStep technology

  Enhanced Intel SpeedStep technology is a means of which allows high performance while meeting the needs of conservation of energy of advanced mobile systems. Conventional Intel SpeedStep® Technology puts both voltage and frequency in tandem between high and low levels in response to the processor load. Enhanced Intel SpeedStep® technology is based on this architecture using design strategies such as the separation between the voltage and the frequency changes and clock partitioning and recovery.

• REGZA 40 "LCD TV emits noise high frequency

  A few months ago, I was lucky to win this TV, a 106 cm LCD Regza HD display.
  I was very happy because I could never afford it myself, and I am very happy with its performance in general.

  I found however is that it emits a high frequency noise that triggers tinnitus in my hearing. (For tinnitus are a squeaking noise acute heard by people who have damaged their ears, sometimes called ringing in the ears).

  I guess that my hearing is already sensitive listening to lots of live music over the years, but I think that this noise is excessive.
  I think that a monitor of this size is by using a good amount of power and maybe feeding could be too work itself.

  The monitor makes this noise at a constant level even before the start of the sound of the TV show.
  I'm curious to know what the suggestion forum users to reduce the background noise?

  The monitor is still under warranty because it is only 6 months old.
  I wanted to be prepared to discuss with the Toshiba warranty people if the forum users can suggest, first, what could be the cause of noise and on the other hand, the possible ways to address the issue.

  Thank you petekey4

  Hello Pete

  As you can see it's Toshiba computer forum and I do not think you will find a lot of people here who want to discuss LCD Toshiba TV.
  In any case, if the TV is new and with valid warranty the best option for you is to contact the service people and let check your new TV.

  I have Satellite R630-130

  I hear a grinding of high-frequency quiet boring when I put any device in USB (mouse, for example).
  The location of Squeak is the "caps lock" key
  When CPU loading more than 50% or I'm in the BIOS the squeaking is disappears.

• Satellite A100-847: is artificially capped in BIOS RAM frequency?

  Well, this question has been asked before, but in a somewhat different way. The thing is that the CPU runs at 667 MHz and Intel 945 PM Express supports aliases PC5300 memory at 667 MHz. notebook was shipped with 512 MB of memory 533 MHz, so now I have two options:

  1. buy an another 512 MB of PC4200 RAM
  2. do not use it and buy two sticks PC5300

  I think there should be some benefits of running of the synchronous RAM with CPU, all the new RAM does not work at a slower frequency (or even does not work).

  See you soon.

  Hello

  667 MHz memory modules are a little faster than the 533 MHz modules, but the difference is small, and you will not see the benefits of great performances.

  If you want to use the 667 MHz speed, you need to use both modules with 667 MHz because
  If one of the modules will support 533 Mhz the other module (667 mhz) will also work with 533 Mhz max

• Maximum frequency of RAM to Satellite C650-1CC

  Hello

  I want to buy RAMs again, but I know Don t, how is the maximum frequency, which can use my cell phone. If he isn´t no need to buy a RAM with frequency with 1600 MHz for example.
  Now there's the Rams with 1066 MHz frequency.

  Thanks for the reply

  Satellite C650-1CC (PSC08E-03H006CZ)

  According to specification for laptop, your laptop can be upgraded up to 4 GB. For the moment, there must be 3 GB inside and one of the modules is 2 GB. Only thing you can do is to get the same second RAM and use 2 x 2 GB. It must be DDR3 1066 MHz (PC3-8500).

  You must use the identical two Rams and you will have only a few compatibility problems.

• CPU frequency and bus on Satellite M30 is too low

  Hello

  The processor and my Satellite M30 bus seems to be significantly under speed. According to Windows XP Pro and Solaris Nevada, the processor is clocked at 600 MHz. The frequency of the BIOS, scaling parameter is set to "Still high", and I tried to disable ACPI in the operating system (ensuring no interference on the software side), without result. Power in the Toshiba Power Saver settings are all maxed out, so no scaling should be there either. Intel Processor Identification Utility reports the following:

  Reported expected
  Speed: 1.60 GHz GHz 0.44
  System bus: 400 MHz 294 MHz

  Note that the tool uses algorithms to determine the speed, rather than trusting the value returned by the operating system, that one of her aims purposes is testing for fraudulenty CPU overclocked by OEMs. The speed as it is for me is even more disappointing. I don't know how long it has been like that, but one thing to note is that the motherboard has been replaced last summer.

  Someone has an idea what here? Thank you.

  Edit: I also loaded the CPU with CPU-Burn to see if some heavy loads would get understandingly frequency. It has no effect.

  Hello

  If you use the advanced search option, you will find a few similar topics with the explanation very clear why unit works with 600 MHz only.

  In any case, after the replacement motherboard service must blink mainboard firmware. After doing this it will work at full speed. Because of this, I guess they forgot to do.

  It is not a big problem. Please contact again and explain the situation.
