That means recommended recommended for an ASM diskgroup to maintain production database?

Dear Experts,

That means recommended recommended for an ASM diskgroup to maintain production database?

+ DATA

to keep the redo log groups redo1a, redo2a, redo3a with 3 members = redo1b, redo2b, redo3b, redo1c, redo2c, redo3c

to organize 3 controlfiles

organize storage of data files

to keep the index tablespaces

How many disk (as a point of reference)

+ FRA

Where to place archivelogs

Thanks in advance,

Kind regards

IVW

Salvation;

A good practice is:

+ DATA holds:

  • Redo log files, Member 1.
  • Control file.
  • Data files.

+ FRA holds:

  • Redo log files, Member of the 2.
  • Control file
  • Backup of files: archived redo logs, control automatic file backups, spills auto backups, copies, backup sets, flashback logs.

This is the distribution of files most used; but always distribution will depend on the size of your database and how do you set up your database. Remember that you need to know how your database works. As Aman said in another post, distribution of files depends on how many disk groups you can have, depending on the speed of the disc.

Kind regards.

  • The antivirus that is recommended for Mac?

    None are required or recommended beyond what is installed with OS X. If you have an adware:

    Remove the browser pop up problems

If you need antivirus protection Thomas Reed recommends to use ClamXAV. (Thanks to Thomas Reed to this recommendation.) You might consider adding this Safari extensions: Adblock Plus 1.8.9.

    Open Safari, select Preferences from the Safari menu. Click the Extensions icon in the toolbar. Disable all Extensions. If it stops your problem, then re-enable one by one until the problem returns. Now remove this extension as it is the origin of the problem.

    The following comes from user stevejobsfan0123. I made minor changes to adapt to this presentation.

    Difficulty of pop-ups in browser that support Safari.

    Common pop - ups include a message saying that the Government has taken over your computer and you pay release (often called "Moneypak"), or a false message saying that your computer has been infected and you need to call a number of tech support (sometimes claiming to be Apple) to get it to be resolved. First of all, understand that these pop-ups are not caused by a virus and that your computer has not been assigned. This "hack" is limited to your web browser. Also understand that these messages are scams, so don't pay not money, call number, or provide personal information. This article will give an overview of the solution to remove the pop-up window.

    Quit Safari

    Usually, these pop-ups will not go by clicking 'OK' or 'Cancel '. In addition, several menus in the menu bar may become disabled and show in grey, including the option to leave Safari. You'll probably force quit Safari. To do this, press command + option + ESC, select Safari, press on force quit.

    Relaunch Safari

    If you restart Safari, the page will reopen. To avoid this, hold the "Shift" key when opening Safari. This will prevent windows since the last time that Safari was running since the reopening.

    It will not work in all cases. The SHIFT key must be maintained at the right time, and in some cases, even if done correctly, the window is displayed again. In these circumstances, after force quit Safari, turn off Wi - Fi or disconnect Ethernet, depending on how you connect to the Internet. Then restart Safari normally. He'll try to reload the malicious Web page, but without a connection, it will not be able to. Leave this page by entering a different URL, i.e. www.apple.com and try to load it. Now you can reconnect to the Internet and the page that you entered is displayed rather than the malicious.

    IPad disabled with thousands of pictures of children that are not backed up with iTunes or icloud. Recommendations for the recovery of photos please?

    Sorry, but if your device is disabled and you have no backup, then you won't be able to save the data on the device:

    https://support.Apple.com/en-us/HT204306

    You should back up your device regularly to iCloud or import your photos to an application on your computer. Otherwise, you will be risking losing those photos. If your device has been lost, stolen, or crushed by your car, you'd be in the same situation. Really sorry for your photos.

  • What is a VPN solution that is more stable than IPSEC VPN? What is the latest version of VPN client recommended for Windows 7 & 8 users?

    Hello

    I would like to ask a few details & concerns on our existing VPN configuration.

    1. What is the Cisco VPN client recommended for users of Windows 7 and 8? Is there an official documentation for this Cisco? We currently use customer VPN Ciso 5.0.7.

    2. we are running IPSEC VPN with only 1 gateway & only local authentication (No ACS) for our client. Recently, we have some concerns that they are the VPN connection is down. Whereas if I'm the one connected to the VPN, my connection is stable. Is there any point that we must consider up in the network. Is there a better configuration or solution that we could recommend to the customer as SSL VPN?

    3. If you want to use SSL VPN anyconnect secure mobility & we want to implement redundancy on the FW, how will the license work?

    Thank you!

    An AnyConnect-based VPN is the replacement recommended for remote IPsec VPN access. (source)

    AnyConnect can use SSL or IPsec (IKEv2) for transport.

    For an ASA redundant firewalls (running 8.3 (1) or later) any permit required AnyConnect are shared between them. that is, you just buy licenses for a member of the HA pair. (source)

  • Recommendations for an application Try & Buy PlayBook of expiring.

    I have a PlayBook application that I want to distribute using Try & Buy. If I understand correctly, I am responsible for creating the logic which expires the application X days after installation. I need to do so that the user is not able to always uninstall and reinstall the application in order to extend the trial period. From my research, it seems the phone apps have the ability to store the date of the initial installation of storage 'persistent' which is not deleted on uninstall. The PlayBook has this type of storage? I am familiar with PlayBooks file structure so I know I could put a file in the shared files box, but it would be easy for the user to find and remove.

    Someone at - it recommendations for a good way to expire an app PlayBook in a way that prevents to uninstall/reinstall in order to avoid the period bypass trail?

    Thank you for your suggestions

    I don't know what the Android player support for payment (if anything), but I think that the other three environments now support payment. You can read the information on in-app purchases even if I do not remember the term 'license key' is clearly stated in the API documentation. Easy to find if you need.

    I don't know how that would solve the 'problem' with people from uninstalling the app and put it back, however. There is still no mechanism that you can use to save the State that persists through the sequence to uninstall/reinstall.

    I would say also that it may well be the best approach "structurally", you may not be happy with some of the side effects resulting from running App World. Specifically, I think that your application would be regarded as 'Free' and listed with free applications, which can mean you end up much lower in lists, because while you can get a lot of installs, you can get some shopping and so some good reviews.

    I can not advise other than to say that according to my understanding that you could do a mechanism to try/buy actually there apart from the thing to uninstall/reinstall.

    Personally, I think I have just limit my trial version to ensure that certain basic features disabled and so inefficient. For a few dollars, if the trial just gives people a general feeling of the product, and they really are the prospects, they will simply say "hmm... doesn't look bad" and pay the $2 or something else...

  • Is have RAID (1 + 0) so that Failgroups for all ASM ASM starts is a well-known best practice?

    Dear Experts,

    Is have RAID (1 + 0) so that Failgroups for all ASM ASM starts is a well-known best practice?

    Having both is the best practice

    • RAID (1 + 0)
    • ASM Failgroups for all ASM starts

    Thank you

    IVW

    You can create groups of ASM disks with normal or high redundancy or specify external redundancy. It depends on your reliability requirements and storage performance. Remember that ASM is not RAID and redundancy is the base file. ASM uses alternating devices. Oracle is generally recommended to have redundancy of storage. If you have RAID redundancy at the level of hardware controller or storage, Oracle recommends to configure ASM disks with external redundancy groups. Redundancy of the DSO is only between groups of disk failure and by default, each device's own failure group. Of course, you always want to make sure that you do not rely on redundancy of data between logical devices or partitions residing on a single physical unit. Compared to external RAID redundancy redundancy ASM using will give the DBA more control and transparency on the setting of the underlying.

  • Current recommendation for a hosting partner?

    I found a good convo here 2013 which resulted in a recommendation and a few stay away froms. But it was two years ago. Much can change! Who would you recommend for a good partner hosting today?

    My husband's small businesses are besieged by what is probably a problem routing or peering at Cogent. Nevertheless, our host, Newtek (previously Crystaltech), nor our service provider are ready to help - isn't that these situations can be resolved, from what I've heard of professional networks and others on the ' net to complain of similar problems. (And help, I mean to have someone in their network operations group call someone down the line in hopes of getting the necessary attention to solve the problem.)

    We have no choice in providers due to its location. So, it looks like my best result by solving the problem is going to be switching hosts. I don't want to - we've been with them for 15 years, no joke! But... this problem went from something that pops up briefly once or twice in the morning at a more often that not, we can't get to our services and routes trace die MOST of the time.

    Vivio Technologies (viviotech.net) has given the green light in the last thread. Additional recommendations? Alternatively, to avoid nightmares?

    Thank you!

    For some sites that I host on the side, I use Hostek and I can't say enough good things about them. Uptime has been great. Help on some questions, I got was even better.

    Avoid Intermedia .net - their support of the CF is CF8 (May 9) and I don't get any indication that they intend to upgrade. I would also avoid HostMySite.com if your site requires safe - specifically juggling tasks of the o/s.

  • Format recommended for the PDF author metadata

    Hello

    I work as a librarian and I am responsible for the Department of the thesis of my University Library. These are filed and archived as PDF files. Some of them are available online, some are not.

    I was told to systematically fill metadata "Title" and "Author" for each PDF deposited in our electronic despository.

    My question has to do with metadata "author." Is there a structure recommended for her?

    As it is I can think of a lot of different alternatives:

    First name last name

    LastName Firstname

    LastName, Firstname

    etc.

    As a librarian, my instinct was to choose the name, first name format (used in the author/creator DC element, for example), but I realized that whenever I have saved the PDF file and then displays the part of metadata (via the shortcut Alt D), it would show "Lastname, Firstname" rather than the full name (for some unknown reason, adds Adobe Pro "" ""). After some tests, I came to the conclusion that the coma was the source of the problem. So I changed my mind and adopted the format Firstname Lastname , but I'm not sure that this is the best option.

    So if I ask you a few questions, here they are:

    -Which format do you recommend for the metadata of the author (if there is one)?

    -Why a coma generates ""?

    Is there a specific separator character that I use when I need to fill two different names (if a given thesis has been written by two different people)? (this issue also applies to metadata "Key words")

    Thanks for your patience and for your time,

    See you soon,.

    JHM

    There are no rules in itself, but the XMP specification defines DC: creator as a ProperName field, which means it must be written in the way he would say - "John Smith" rather than "Smith, John". Finally, it is until you do with data - if your external search system to priority of family name, do it.

    The fields on the tab of "description" of PDF Properties dialog comes from this Document information block in the standard PDF file, which is independent of the XMP metadata. Although these fields of DI are often people will look on, in a formal catalog system the XMP object has priority (indeed, in the ISO PDF/A standard that you are supposed to ignore completely DI fields).

    Document Information fields are stored in the PDF file as strings rather than the XML entities. Commas would confuse the parser in thinking it was to see a table, so they will trigger Acrobat in order to encapsulate the entries between quotes. He will assume a comma and a single space are part of an individual term, if you want to create a list using the semicolons or several spaces between words. Senicolons conquer spaces:

    • Doe, John; Lord Lucan; Barney, the Purple dinosaur will be kept at the "Doe, John"; Lord Lucan; 'Barney, the Purple dinosaur'
    • Is no one, no one will be kept to the ', that is, not a "; person because the spacing is a term separator.

    The important thing to remember is that the entrance of DC: creator XMP is updated whenever you change the author field of DI, but it does NOT follow the same rules. ProperNames XMP are OK with spaces but they don't like commas or semicolons - so the first example above appears in the tree view of XMP as

    1. DOE
    2. John
    3. Lord Lucan
    4. Barney
    5. Dinosaur
    6. the
    7. Purple

    This reinforces the idea of using names as spoken. Lord Lucan has survived his trip to XMP, John Doe became two people. Barney is beyond hope. in many ways.
