Question about the clause for the EVE of BACKUP command

Hello

I would like to know the exact difference between BACKUP CONTROLFILE CURRENT and BACKUP CONTROLFILE CURRENT for INTELLIGENCE in Oracle 11 g. I searched the docs and My Oracle Support OTN, but still I have not found an answer. I would be grateful for any explanation or references.

Thanks in advance.

Hello

Allows to consider from scratch,

What is a controlfile :--> its a small binary file that records the physical structure of the database.
The control file includes:
The name of the database
The names and locations of the partners of the data files and redo log files
The timestamp of the creation of the database
The current sequence number
Control point information

Now, down to backup controlfile--> will have the exact backup of the controlfile used by the database (including the role of the database) Please note that this controlfile cannot serve as a controlfile standby when you try to use it it will return the error

Backup controlfile as Eve--> will anything similar as for the previous command except for the role of database that are not primary indicator but would be pahysical Eve, all other information would be same.. like with it it will not be an exact replica of the primary database.

It is the only difference from what I understand concepts.

  • A question about the REEL in sqlplus command

    Hi all


    I have a question about the order of the COIL and I would be grateful if you could kindly give me a helping hand. Consider the following sql script.
    SPOOL result.txt
    SELECT * FROM mytable;
    SPOOL OFF;
    It works pretty well, and all the contents of the table "MyTable" is exported to the textfile "result.txt". However, sqlplus also prints the number of lines
    Print after each query. So after you run this script, the end of the file, I always have a line like
    ...
    "20541 lines returned"
    How can I avoid this line (the number of returned rows) in my output file?


    Thanks in advance,

  • Question about the purchase of policies in China for commercial purposes

    I have several questions about the purchase of policies. Our company is in CHINA

    1. we have our own product which has LCD display to display certain information with different languages (Chinese, English, German, French, Italian, Spanish, Portuguese and Russian). We need to use Adobe Heiti Std fonts for the Chinese language by commercial purposes. I tried this font in Adobe? Do Folio police 11.1, but is not in this library, your partner gold in China told me this font is part of Adobe Production Premium CS5.5, which we have already purchased from Adobe, it is used freely by the user.

    It is true that we can use the fonts Adobe Heiti Std freely and even for commercial purposes in many products?

    If this font is not free, how can I buy it for commercial purposes in many products? Could be he you pls tell me the person/company contact email or phone number.

    2. we need to use Eurostile LT font for the English language by commercial purposes as well. Is it Eurostile LT available for German, French, Italian, Spanish, Portuguese and Russian as well? and I can not find do Folio 11.1 as well. But some Eurostile Std * fonts appear in the list.

    Use font Eurostile LT? freely for user

    The police in the Adobe product package, but it is not in the Adobe typotheque (Adobe? Do Folio 11.1), then it can be used freely even for commercial purposes in many products?

    Thank you in advance.

    Unfortunately, none of these fonts is available for the user interface of the product. Although Adobe has two of them, we have not the right to sell OEM licenses or the other.

  • A few questions about the difference between the Satellite P70, L70, S70

    Hello, I have a lot of questions about the P70, L70, S70 series that come with a 1920 x 1080 panel.

    (1) what are the differences between the L70 and S70 series? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

    (2) P70, L70, S70 doesn't support a 2nd HARD drive or it's just the P70 series that support?

    (3) all the three (P70, L70, S70 series) come with the same TFT panels?

    (4) of the above series, which supports mSata?

    (5) all the model of each series are delivered with support from mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?

    (6) all the foregoing, are delivered with a S - ATA II or III S - ATA interface?

    (7) who is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.

    Thank you in advance.

    > (1) what are the differences between the series L70 and S70? With the exception of the RAM and HARD drive capacity, books seem pretty identical.

    What models Sat L70 and S70 do you mean exactly? There are different L70-xxx-xxx and S70 models on the market that supports different hardware specifications.

    (> S70 2) P70, L70, support a 2nd drive HARD or is - it just the series P70 that support?
    As you can see in this [Sam P70 HDD replacement document, | http://aps2.toshiba-tro.de/kb0/CRU3903II0000R01.htm] the P70 series supports the 2nd drive Bay HARD, BUT even if there is a 2nd HARD drive Bay, this does not mean that you can use the 2nd HARD drive. In the case where the 2nd HARD drive Bay are equipped with HARD drive connector, you can use the 2nd HARD drive

    I also found the [Sam L70/S70 HDD replacement | http://aps2.toshiba-tro.de/kb0/CRU3703HG0000R01.htm] the document on the Toshiba page and there I see this 2nd HARD drive Bay is not available

    (> 3) all three (P70, L70, S70 series) come with the same TFT panels?
    See point 1). Different P70, L70, S70 models were equipped with different material parts.

    (> 4) of the series above, which takes in charge mSata?
    As far as I know that some P70 models are equipped with an mSATA SSD of 256 GB.

    (> 5) do all the model of each series are delivered with support mSata? For example, it could be that L70 - a - 13 m supports mSata is not the case of the L70-a-146?
    See point 4) not all models supports the same hardware specifications

    (> 6) all of the above, come with a S - ATA II or III S - ATA interface?
    I don t think that SATA III is supported. I guess it would be SATA II

    (> 7) which is the best of these series listed? I'm trying to understand what makes the big difference of S70 to P70 except for the envelope for example.
    Not easy to answer because there are too many models released in Europea.
    And not all models are available in each country. So I guess you will have to look for the models that have been released in your country.

  • A few questions about the upgrade on Satellite A300-144

    Sorry for the typos, English is not my mother tongue.
    I want to ask some questions about the upgrade of a300-144.

    * Some info first.*

    CPU: T2370 ([http://ark.intel.com/products/34445/Intel-Pentium-Processor-T2370-1M-Cache-1_73-GHz-533-MHz-FSB]).
    Chipset: GM965 ([http://ark.intel.com/products/29821/Intel-82GM965-Graphics-and-Memory-Controller]).

    * Questions.*

    1. my frequency of laptop memory at 533 MHz, supports 667 MHz memory controller, memory modules can work at 667 MHz. Is - this because CPU FSB 533 MHz frequency and new processor at 667/800 MHz FSB will fix it or it is hardcoded in the BIOS?

    2 Intel said that the size of max memory for my chipset is 4 GB (2 x 2 GB), but Toshiba says that only 2 GB (2 x 1 GB), who is right?

    3 I know, taken of my CPU is μFCPGA-478 aka socket P, max FSB 800 MHz, max 35 W TDP, so T9500 ([http://ark.intel.com/products/33918/Intel-Core2-Duo-Processor-T9500-6M-Cache-2_60-GHz-800-MHz-FSB]) is a compatible processor or there are some limitations in the BIOS?

    > 1. My frequency of laptop memory at 533 MHz, supports 667 MHz memory controller, memory modules can work at 667 MHz. Is - this because CPU FSB 533 MHz frequency and new processor at 667/800 MHz FSB will fix it or it is hardcoded in the BIOS?

    The speed of the memory is related on the material. This means that the FSB is responsible for the limitation.
    If the FSB would allow support 667 MHz then the memory would also at this speed.

    > 2. Intel says that the size of max memory for my chipset is 4 GB (2 x 2 GB), but Toshiba says that only 2 GB (2 x 1 GB), who is right?
    The memory depends on the chipset. So if the chipset supports 4 GB of RAM, you should be capable of this move to 4 GB of RAM

    > 3. I know, my CPU is? FC-PGA-478 aka socket P, max FSB 800 MHz, max 35 W TDP, so T9500 (http://ark.intel.com/products/33918/Intel-Core2-Duo-Processor-T9500-6M-Cache-2_60-GHz-800-MHz-FSB) will be a compatible processor or there are some limitations in the BIOS?

    It might be possible that the new processor would be fully supported by the BIOS, but in most cases it should not be a problem if the chipset would support the new processor.
    But as far as I know the upgrade of the CPU is not supported by Toshiba or any other manufacturers of portable and its your own risk to run laptop with the new processor.

  • A few questions about the Satellite A100 PSAANE

    Hi friends,

    I have a Toshiba Satellite A 100 - PSAANE with Vista Home Basic preinstalled in it.
    Now, I have a few questions... I mention below: -.

    (1) if I want to format my laptop, I need a CD to install for Vista Home basic... then I don't have this Toshiba CD when I bought the laptop. So how do? question: How can I format it?

    (2) can I change my Vista Home Basic to windows XP? I think it's much faster than this one. is it advisable?

    (3) I have a GB of RAM in the laptop. Increase the RAM? I think that my laptop has become to slow down. is it advisable?

    (4) and on my screen, everytime I try to change my profile screen to windows Classic view, my screen begins to blink. and after a while, the screen turns off. So I can't change that. I put the color scheme of windows vista only. What to do about that?

    Please help me friends. Thanks in advance.

    Kind regards

    Hello

    Here, a few questions about the number:

    (1) usually, you should get the Vista Toshiba Recovery DVD. If you didn t receive this DVD then you can order it here https://backupmedia.toshiba.eu/landing.aspx or you could install the disc of Microsoft Vista.

    (2) of course, you can do this. I think that Win XP drivers can be downloaded from the Toshiba driver page.

    (3) Yes, you can upgrade the RAM. For more information, see your manual or search on this forum for similar topics

    (4) maybe it s associated with the graphics driver. Check if you can update. I would recommend additional check if you are using the latest version of the BIOS

  • Question about the new Yoga 10 HD +.

    Hello

    A few questions about the new Yoga 10 HD + that I hope you can answer.

    I bought the former model, last year. Love the design and long battery life, but a few major questions made me return.

    • Somewhere that I've read that it can not read NTFS on USB so I guess that's the same thing with a NTFS formatted microSD card?
    • Can it read exFAT formatted microSD cards?
    • Anyone who has questions about the audio via bluetooth?
      (I know that BT is not exactly High End HiFi but the old 10 Yoga for some obscure reason - most likely a driver problem which nobody cared to fix - rang * very * worst with visibly distortion while both my phone and a Tablet noname cheap I have zero about fidelity - any of my devices bluetooth audio) I tried aptX or not)

    So to avoid buying it back it also I really I would like to see if I can get my questions answered before buy you.

    While I love the form factor and long term issues above are only two Mayor dealbreakers for me. Bad audio quality = no joy listen to spotify, local etc. MP3s. not of NTFS or exFAT = some great movies.

    My old noname android Tablet really could use an upgrade so I'm really curious it may be, or I should watch the competition and will be form factor and battery LIFE.

    Thanks in advance.

    EDIT:

    If it does not support NTFS or exFAT on microSD card have someone at - he tried ext3 or ext4?

    I mean with Linux Android root, it should be a no-brainer to support at least when it comes to royalties unlike NTFS or exFAT where it * might * have some trouble with Microsoft.

    I used a USB through a USB OTG cable. NTFS or exFAT have been recognized by the Tablet PC. FAT32 is seems to be the preference.

  • A few questions about the use of data and Cliq

    I have the cliq, however I chose to not get 3G (so I bought full fare). So I have a few questions about the phone and the use of 3G / 2 G/Edge:

    1 - is possible to disable completely the 2G / 3 G/Edge? I know you can switch between them, but are anyway just tell the phone to stop using them altogether since I'm not subbed to the service?

    2. when the update takes place, I guess we'll have to reconnect motoblur and etc, but if I don't have 3 G will I have motoblur connection problems after the update? Or he keeps the latest wifi settings so that it would connect to wifi to connect. When I first got my phone it was not a problem b/c I had 3G for the first month.

    I hope that makes sense, thanks!

    To stop all the data, I would like to download an application called APNDroid. He cut them all down. When you log on to blur you have 3G or WIFI doe this without getting a timeout error. During the process of setting up your Blur account, you can press the menu button and set up your wifi to work, this will connect you to Blur and your phone will be connected to the blur. If I were you I would be rethinking to do a data plan since you are really losing out on most of your main features of phones. It's your choice, however.

  • Ask questions about the functionality of EA8500 MU-MIMO

    Dear Linksys

    I bought EA8500, and it arrived today.

    I have two questions about the functionality of MU-MIMO of EA8500 AP.

    1. I want to compare the performance between SU-MIMO and MU-MIMO, but there is no option to control this feature in the router admin page. Is that one of the possible ways?

    2 EA8500 supports 1733 Mbps wireless speed, but it resembles the speed of 1 Gbps ethernet cable.

    This router supports really speed 1 Gbps ethernet? or y at - it an option to support more throughput as the aggregation of links?

    Thank you

    Hi, hyeonu. For your first query, it is not possible because there is no option to disable the feature of MU-MIMO on your Linksys EA8500 router. In addition, with regard to your second, you can get a higher throughput of 1 Gbps since this is the maximum capacity of your ethernet connection.

  • Question about the charging light on the venue Pro 11 (5130)

    I'm curious... read these discussions in recent weeks... found this work with the Tablet for about 2.5 hours after... I was up to 75% of battery. Connect the tablet to install a software... noticed 75%, not charging. Stop... removed the battery and put it back... He then read 75%, in charge. OK... so what's fixed now... a question about the manual of the system. Said that when the battery is charging, a white light is supposed to be on... where? When that I start, I see a momentary white light at the top of the screen, by the front camera... but when it is plugged and the loading and off... white light no.... No a - I misread? Thank you

    Light (color is white when the load) is located next to the power switch (top, right). Mine re-load very fast.

    White light goes off (or does not) when the Tablet is fully charged (the light on the charger is always on when it is plugged into the outlet)...

  • Question about the strength of password

    (do not ask questions about the recovery of the password, so please do not report this thread)

    OK, I heard that the virus can change the password on a computer.

    But if you have a password very complicated (for example, one with a lot of numbers and other things), it will be more difficult/less likely for the virus to be able to change your password?

    Yes.  A strong password is, it is more difficult to crack.  For more information, see create strong passwords on the Microsoft online safety site. Boulder computer Maven

  • Question about the differences in commands

    Hey guys -.

    I just had a few questions about the differences between orders that seem to perform the same function.  Can you let me know if an order is more preferable to the other and what the difference is.  I would really appreciate it as it I currently practice some INE laboratories and I see that orders change from lab to lab.  Thanks advance!

    1. When you write a static NAT for specific host 1 - is - this important if I understand the 32 subnet?

    EX: static (inside, outside) 1.1.1.1, 2.2.2.2 VS static (inside, outside) 1.1.1.1 2.2.2.2 netmask 255.255.255.255

    2. when I'm setting up a router as a CA server and it is necessary to "export" the key, whatever my method of exporting the key?  If so, in which method call for which solution?

    EX: key export cryptographic rsa ciscox pem URL nvram: cisco VS. exporting key 3des cryptographic ciscox pem 3des rsa terminal cisco

    3. If I have to mark a packet with a DSCP of X value, matter if I use the 'set dscp' VS 'set ip dscp?  If so, what is the difference?

    FXY

    Policy-map X

    class X

    the dscp X value

    VS

    Policy-map X

    class X

    X ip dscp value

    I guess pertaining to 2, if i was speaking in terms of from a cisco router to another cisco router - would terminal be acceptable?

    Yes, the "Import cryptographic key" command can take a url and also from the terminal entrance. In this terminal case wil is much easier.

  • Recently bought a laptop computer; A few questions about the offer Upgrade to Windows 8

    I have a few questions about the Upgrade of Windows 8 offer for new computers.  I recently bought a Toshiba Satellite S855-S5268 of amazon.com, which came with Windows 7 Home Premium.  Toshiba already has a beta version of drivers and utilities for Windows 8 for the S855 on their Web site.

    (1) I bought my laptop in July of this year, and I've not yet registered for 8 Windows Upgrade offer with Microsoft.  Am I still eligible to receive the upgrade, if I sign up soon?
    (2) if I buy the upgrade through this offer, I'll be able to download an ISO file so I can burn the installation media, or do I need to upgrade to Windows 7?
    (3) if I will be able to burn the installation media, I'll be able to erase my hard drive and do a clean install of Windows 8 (which I'd rather do, I have a lot of backups of my data).  I am aware that I would probably need to provide my product key Windows 7 Home Premium 64-bit OEM during the new installation, because it is an upgrade and not a full version; This isn't a big deal, because my Windows 7 Home Premium 64-bit OEM product key is stuck at the bottom of my laptop.
    (4) my current copy of Windows 7 is activated by seeing my BIOS (I have a traditional BIOS, not a UEFI).  If I had to switch to Windows 8 and decide then I'd rather back in Windows 7, for example, a few months later, I'll be able to do that (I burned recovery of Windows 7 with the Toshiba utility disks, which I did), and Windows 7 will continue to activate by seeing my BIOS, even after the installation (and later remove) Windows 8?
    Thank you very much!
