How fast can catch mrp?

11.2.0.2 on Solaris 10

Lets say something has gone wrong on the side pending and there is a gap of 1 GB with a value of redo. After you fix the problem, can mrp quickly to catch up and apply 1 GB or should we take an incremental backup of primary RMAN and rollforward eve?

What is the limit; That is to say. say if it is greater than 1 GB, go for RMAN incremental rollforward and if the gap is less than certain GB/Mo leave mrp, apply it and synch primary and secondary

Hello;

Depends on the network. I had once 250 newspapers (100 MB each) and it took 15 minutes, but I have a fast network. MRP can be applied very quickly.

I would try taking upward because there is no risk and the RMAN solution, although very good has more.

Best regards

  • How fast can get a TCP read?

    LV 2009 + WIN 7 with 6 GB of Ram.

    I acquire two analog channels as a word of 16 bits each and adding a CRLF at the end example: 1234 567 \r\n

    These data are acquired to 50ms intervals and sent over a link WiFi for my notebook running code LV.

    I know not how fast the "TCP - Read" function can work and which mode (it has four options) to choose if I do not miss any incoming data...

    Now I get some data in French - initially rather quickly and after a few seconds, it slows down the consdierably. I'm running the TCP-read inside a timed loop and I tried various intervals from 10 ms to 500ms. The largest value works OK, but I need the fastest possible. Tips how to handle this?

    My code is attached. (The passage DIO works very well)

    Even if the passage DIO works, it doesn't make sense to use a sequence structure.  It would be better to change the Standard mode and the 100ms Timeout value instead of "wait for next"millisecond"Multiple" as leading to uneven wait times.

    TCP Read should run very quickly, subject to any waiting period that you set.  You should never lose data in any mode, although there is a possibility to receive a partial when you use Standard mode or immediate (unlikely in your case since you read so little data).  The operating system will be buffering of data not read for you.  If you want the fastest possible exchange, divide your code in two while loops, one for EID and the other for the series.  Serial communication can be simply a normal life while loop, with the reading of TCP dictate the timing.  Set a long timeout in buffer mode and the loop will run as quickly as it receives data.

    Also, when the loop ends, you must close TCP connections, not just one of them.

  • How fast can I send using SPI commands in a NI8451 of python?

    I use SPI communications with NI8451 leave a python code. I want to know how I can increase the speed at which I can send orders? and what is the maximum that you can go. I'm developing an application in real time if I want to continue to read the data as soon as possible.

    I don't think that there is a way to overcome this, since the selections of line and to update is completely made of material by the microcontroller inside the 8451. The rate at which data is sent to the microcontroller depends on how fast the code on the hosting platform is running and the time it takes for data to cross via USB (which can be ignored).

  • Upgrade of RAM i7 540 how fast can the processor actually use

    I just got a 540 and I want to know how fast RAM i7 processor is able to use to my advantage. The BIOS can deal with setting parameters at a higher speed of RAM?

    Second question, the system tolerates 1.3V RAM?

    Standards JEDEC and Intel Haswell only supports 1600 MHz CL11 at 1.35v

    You can install RAM more fast (probably up to 1866 MHz depending on availability), but it might speed up to 1600 MHz.

    Note that faster RAM installation also slightly increases the temperature of the CPU.

    Don't lose sleep on it, you hardly notice the difference anyway.

    Before I forget, do not install any RAM with a voltage higher than 1.35v.

    # You have not given any information, except for what you are trying to run.

    As far we know you run with some processors Sempron/Celeron and 512 MB shared memory with an on-board video camera.  In addition, you might have a suite of protection oversized running on your system to keep you safe from Internet predators and a bunch of other things you love continues to run in the background.

    Here again, you can have a dual core or higher processor 1.8 GHz or more fast speed with 1 GB or more of memory and a 512 MB or higher video card (do not share memory with the system) which has installed the most recent drivers.  Also you can have only a basic product antivirus running, by using the built-in Windows Firewall and you want to keep your system with as little as possible run so that most of your resources are available.

    Probable - in any case - other than generalities such as:

    (1) make sure that few runs when you play the game (with the exception of the game) as possible.
    (2) make sure that you have the latest video card driver installed for your video card.
    (3) make sure that you have the latest driver installed for your motherboard chipset.
    (4) make sure that you have the latest audio driver installed for the audio device.
    (5) make sure that you have the latest network driver installed on your device on the network.
    (6) run the game with its smaller settings with the same extras disabled as you can stand it.  Shadows are nice - but will slow down your system.

    And the advice that you said that you do not want to (while remaining general because we do not know the details of your system):

    (1) buy a more grand/more fast video card to replace yours.
    (2) buy more memory system in case you run low during playback.
    (3) replace your processor with the highest that will take care of your particular motherboard.

    And the most extreme:

    (1) buy a system that has a little above the minimum specs for the best interpretation of this game is that you are trying to play.

  • How Illustrator can crossed fast? (as 'select the fill - same - color")

    Hello. I have a curious.

    If I want to select objects that same color to fill in the document, I can use the function "select fill - same - color" in Illustrator.

    It's so fast. less than 1 second.

    But, if I want to do in Javascript, I can't do it as fast.

    for (i = 0; i < activeDocument.pathItems.length; i ++) {...}

    If the document has 10,000 items, above script cannot complete in same 60 seconds.

    How Illustrator can crossed fast?

    Is there something else?

    Unfortunately not support Javascript. Only the long long way.

    But you can call an action with the CS6 script: select a path in your scipt and call for action (in which is: select same fill color)

    By the way: you could solve your problem last? (http://forums.adobe.com/thread/1310394)

  • How fast your imac boots?

    Hi guys!

    Just interested in how fast your iMac boots (as the minutes and seconds) until your first open application is fully sensitive? I end 2013 iMac 21.5 "2.7 GHz intel core i5, 8 GB of RAM, running El Capitan and it feels long enough. Also after the commissioning of the applications such as Chrome and utorrent open very slowly. After that, everything works fine.

    I am curious and just started my Mac, a little old 21.5 inches mid-2010 i - Mac. I was curious because she feels slow to start sometimes, however, I was pleasantly surprised with the Dell laptop, my employer has provided me with (but it is bogged down with a lot of security software). The Mac has a 3.06 GHz core i3, 12 GB of RAM and runs OS X 10.11.6. It is a standard unit of an Apple store close to November 2010.  It took 88 seconds to load the office then another 8 seconds to load a web page. Then I opened the mail and I was 1 min 43 seconds by the mail of synchronized time. It doesn't have a HD 7200 RPM, which helps, but an SSD would be probably faster (I thought to start from an external SSD but the processor is getting pretty old, I can be close to need/want of a new machine). The Dell takes a little more than twice as long. Up to what speed (slow?) your machine starts?

  • Satellite A200: How long can I work on battery

    Hello

    I bought new Toshiba A200-1AE with Windows Vista and I have a question I can find how long can I work on battery? Because I can not find it. Only one percent of the battery.
    Help, please.

    Hello

    It's not easy to say how long you will be able to work with the battery power.
    Battery working time depends on the use of the laptop. If you run applications of high performance such as games, video software, etc. laptop battery power down much faster!
    Why? Because all the laptop as the CPU, GPU, HDD parts, cooling modules are run with maximum efficiency. All these pieces of waste and the need of the battery power!

    Are you using XP or Vista? Vista needs much more resources than other systems operating Microsoft. It wastes more battery performance. This means that the laptop will run a lot more time with installed XP as with Vista OS by using the battery.

  • the variant attribute value - how fast it is?

    Hello

    There were days OR presentation on attributes of type variant. There are example saying that variant can be used to remove duplicates from table 1 d and this supposed to be a very quick solution. I did some tests and it seems that is not:

    On the other hand the variant is very fast research once all atrubutes are implemented.

    My question is how fast is being variant attributes and how this structure variant is allocated and stored in memory.

    Excerpts from VI attached.

    LabVIEW manages memory for you.

    However, if you make too much reallocation of arrays of surfaces, you might run out of contiguous memory and thus running out of memory, memory fragmentation can cause problems.

  • HP 6470 b 2nd hard drive upgrade. How fast this port works on? SATA I, II or III

    HP 6470 b 2nd hard drive upgrade. How fast this port works on? SATA I, II or III

    I want to put in a 60 GB SSD into the CD slot and want to see how fast it will support as this will be used for the Cache

    Thank you

    The published information is not explicit; He says only: SATA for the expansion Bay while the main hard drive Bay expressly says SATA-III. However, given that this isn't just an optical drive Bay, but also a general 'Bay expansion', it is safe to assume it of on the same SATA bus as main drive and is a SATA III interface.

    Data sheet

    6470b is also supposed to have a slot for a WSSD mSATA, but he is not described in the Manual:

    Manual

    Obviously the WSSD would work better for cache but you can use a 60 gig SSD in an expansion bay for both cache adapter. Even if the connection is SATA-II, it will be much faster to work for a cache of acceleration.

  • how fast windows 7 should start up

    how fast to, I have a dell 760 optiplex running windows 7 pro 64 bits 8 gig of ram I terrabyte or hard drive, can someone tell me how fast it takes to start, and after the start page were the windows logo is, after that the screen should it go directly to a blue welcome screen or should it be a black screen before

    John

    Depending on your system anywhere from 20 seconds to 3-4 minutes.  No way for us to know because you didn't don't give us all the specifications of the system.  For example you have a SSD?

    It may be 30 seconds after the logo screen until the desktop becomes visible.

    If you think it's slow, you should check which takes over at the start.  Suspect, that you may have added a lot of software that starts unnecessarily

  • I just new iPhone 7 &amp; when I transfer, none of my music is available offline (purchased and apple's music program), trying to figure out how I can download it all at once, without having to enter each individual album and click the cloud

    Just got the new iPhone 7 & when I transfer iphone 6 iPhone 7, my music has arisen on the phone, but none of my music is available offline, try to understand how I can download all at once for use offline, without having to enter each individual album and click the cloud.  I have a lot of music on my phone, would take me forever to individually download each album one by one for offline use.

    I have both bought albums/songs itunes and also many of the monthly music apple package.  In any case for all it all at once?

    Hello

    You must use the same identifier apple

    Go down homepage itunes page where it says more about this music bought to display

    And download

    For music apple if its does not sign of apple ID then sign.
