retention policies different for RMAN

Hi@all,

on our DB with RHEL 6 and Oracle 11.2.0.3.0 Server, we create the following backup with RMAN:

-every day at the level 0 backup 23:00

-daily at 05:00, 11:00 and 17:00 level 1 backup

I activated this retention policy:

CONFIGURE RETENTION POLICY TO RECOVERY OF 7-DAY WINDOW;


Each backup is so obsolete after 7 days. We use the control file and catalog any recovery. We get backups so in front of the SLA.


Now (in front of our physical disk space) I want to spend the retention policy to the following:


-Fullbackups (level 0) should be obsolete after 7 days

-incremental backups (level 1) should be obsolete after 2 days

-arc. redologs should be obsolete after 7 days (I like to use LogMiner and especially I need newspapers in restoring arch in the last 7 days in our society)


Is this possible in RMAN to set different retention for different types of backup strategies?


Thanks for your help and best regards,

David

Now, if you want to know exactly how oracle will include in the scenario you are asking (how to do different types of backups behave in what concerns a retention of "redundancy" policy, I would suggest test you.)  I could knock out this test in 30 minutes approximately.  It would be good for your career (on many levels) for you to perform this test for yourself.

  • RMAN retention policies

    We seek two retention policies for our backups. retention of 30 days for all backups on TAPE and 7 days of retention on all backups on DISK. If we define the retention at 30 policy, drive could not accommodate all the backups on disk at the same time, we need backups on tape for at least 30 days.

    Any ideas?

    You have a block of code in your script to delete obsolete backups... replace that with two orders (a global and one for the disc). You would still have 30 days retention policy

    RMAN TARGET /.
    CONFIGURE RETENTION POLICY TO RECOVERY OF 30-DAY WINDOW;

    Sync is currently synchronize personal data to other devices.

    Some like to use Sync as a backup system to a computer and is not implemented reliably and can fail at any time, especially if you reinstall Firefox and you want to retrieve the data stored on the server.

    The services.mozilla.com web page is where you can check your sync account.

    This server does not support the connection through Persona (Persona no icon on the login page) and requires its own password.

    Persona is just a special way to authenticate on the Mozilla servers independently of the web page (Mozilla server or subdomain).

    This requires JavaScript transmit these data to back and forth between the servers, so that the server must support this way to authenticate.

  • Using tape for RMAN backup concerns

    Dear all,

    I use the library of networker for rman backup. I have some problem/question about what I don't use catalog db. Here it goes:

    1. think you that automatic backup controlfile should set to strip? or better to keep in the disc.

    2. How can I configure autoback controlfile format on TAPE?

    3. If I need to restore control to another HOST file, how can we do this?

    4. I've read a few books we can't CATALOG element of tape backup. If it's the fact that, after the disaster, how do I Catalog backup piece and restore this backup piece in another host?

    Kind regards

    Hello

    1 when RMAN channel tape is allocated when running RMAN backup, autobackup controlfile will be created in the Ribbon to place on the disc. If structural change to the database is made, for example by adding a new data file, then the controlfile autobackup will be created in the disk, regardless of the device type of the default RMAN configuration.

    Control file autobackup after structural changes of data and the Type of device SBT_TAPE (Doc ID 1190354.1)

    2. set below:

    RMAN > CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE 'SBT_TAPE' TO '%F ';

    3. If the automatic backup location is not the default location and then set the location first.

    Use this command to set the location:

    RMAN > SET FORMAT FOR DEVICE TYPE SBT_TAPE AUTOBACKUP CONTROLFILE to '< auto="" backup="" format="">';

    Then use the command

    RMAN > restore controlfile on "" automatic backup;

    4. starting with 10 g, it is possible to use the rman CATALOG command to add backuppieces stored in the disc to the rman repository. But it is not possible to use the order CATALOG for items stored on TAPE backup, but note below explains undocumented commands to add backuppieces stored in the RIBBON for the repository.

    I am very new to dream. I created a simple site that worked very well. I tried SEO booster and was checking on things different (for example Goigle webmaster). I don't know exactly what I did, but now when I type in my site it tells me that the page cannot be opened because it was redirected too many times...? Help, please!

    Let me add some details to the choice in the scenarios you have for the use of domains.

    The areas are to simplify all kinds of activities on the Internet for users. Instead of addressing your email to go to the software from e-mail server to a computer with the IP 113.78.59.238 number, users can simply run their mail to "hannah" @ "gmail.com" or go to the website to "gildedgraces.com". This makes things a lot easier for users, but requires a little more difficult techniques backstage, because Internet computers connected and hardware (servers, tablets, phones, refrigerators) have only single numbers, not names. So, how internet needs to know which computer manages all emails for "@gildedgraces.com", and where physically this site 'www.gildedgraces.com '? This is where the "Domain Name Servers" kick in. They maintain long lists of these domain names, with references to the IP numbers correct and up-to-date. In this way, technicians can also easily Exchange computers, servers, connections, where a site is moved to another host, or when a server suddenly collapses. These things will happen, things have to change. They want to update certain IP numbers in the list on the DNS servers. I have it?

    So in order to get a Web site running, you know where your domain registry database is guarded and kept safe, and where your Web site is physically located.

    Note the difference between DNS (or servers) and the service (or Web servers) throughout all the instructions and documentation.

    Now, have a look at this PDF that was returned by Brad, in his response above.

    The domain name can be registered at any domain provider and the registry itself is not always need to reside there. You could relegate (you might say "move" or move) the registry for the DNS to another provider (like BC) service. In such a scenario, he must tell the provider holding the credentials of your registry, to redelegate it in British Colombia. That's what the article 4 in the PDF file. And of course, BC DNS service can internally so all applications for this field to their own web server.

    You can also choose to keep your current domain provider maintains the registry, but that their DNS servers before any request of this area on the web servers of British Colombia, where your site is published. This is typically a necessity for registrations from non-American, since many extensions of national domains (such as .nl and .de) can be recorded by suppliers outside of this nation. So the registry simply cannot be moved to an American company (it's a legal thing). In such a situation, article 6 of the PDF comes into play, describing what BC would normally internally: to the domains of the physical location of the Web site.

    Without a doubt. If you have multiple databases in your env, you can pass through targets and data bases. Say, if you have four databases, A, B, C & D, you can create catalogs in A and C and C & D grid in a catalog and a & B to C catalogue. If you have only a database in the environment, I just do not use catalog.

  • If the SID can be different for a standby DB?

    Hi all

    Greetings!

    I create a 11.2.0.3 standby in our environment recently. Sleep works very well (I'm yet to complete the HA test in all cases). I'll have my sleep instance_name (SID) different from primary DB, and archive logs are synchronized. I was wondering, if it is mandatory to have the instance_name to be same on the primary and standby. We had some problems with our build POC with the same SID, and I saw that the grid infrastructure requires the db_unique_name to use for recording as part of it. So I took the day before to have a different SID, and it worked from the beginning that I am building. I talked to a few of my colleagues DBA and none did not on that. I just wanted to be sure that nothing came out of the box.

    I said only DB_NAME should be the same, and DB_UNIQUE_NAME must be different.

  • Why Firefox keep showing a strange police cursive for certain sections of text on websites like Wikipedia?

    For past month or two, when I consult Wikipedia a few other sites, sections of text are displayed in a large, cursive font. I can't find any rhyme or reason to what sections show this way. This isn't the case at all sites but there are a couple where I'm the see. This makes things really difficult to read. For a screenshot, see this file I put on YouSendIt , YouSendIt.

    Such behavior is usually caused by another font that does not work and that Firefox replaces with the following font in the list. In this case, you can check the Arial Cursiva police.

  • GetActivePanel seems to behave differently for ConfirmPopup / MessagePopup and FileSelectPopupEx

    Hello

    I have a GUI with a XY Chart and to change the style of mouse (by default against the hair) and indicate the coordinates of graphic I use a timer control where the callback checks the coordinates of graphic.

    Because it can happen that a pop-up Panel appears, I also check the active panel is the current Panel to avoid having a mouse cursor focus on the pop-up Panel.

    The code is as follows:

    int CVICALLBACK MouseCursorTimer (int command face, int, int event, void * callbackData, int eventData1, int eventData2)

    {

    If ((événement == EVENT_TIMER_TICK) & (UtilityGetActivePanel () == sign))

    {

    the details of the graph using GetRelativeMouseState () and GetGraphCoordsFromPoint)

    ....

    As expected, the cursor will move style according to the position of the mouse. If I view a panel using InstallPopup () (which appears on the top of my chart), the cursor will move if placed default style on the popup panel. So far so good and I was happy--until I discovered that the other popup panels may behave differently...

    If I call ConfirmPopup or the cursor style MessagePopup mouse does not change, for example, it is shown as a focus, even if the mouse is placed over the popup panel.

    Interestingly, FilePopupEx () behaves correctly. Somehow, it seems that the Panel handle returned by GetActivePanel () depends on the pop-up Panel function called... It is by design or can it be fixed?

    Thank you

    Hi Wolfgang,.

    I slightly modified your program adding evidence when you set the cursor cross. It seems that the program sets the cursor again when navigating in the menu, even if the system is not honored by this parameter (it is probably correct that cursor remains that by default within the menu, right?). Question is why the system shows the cursor cross inside the pop-up window, but it is indeed honour your choice!

    As you already put out, the problem checks according to the State of the cursor when the window is issued and is not the type of window: I've added two options in the menu to display a panel with InstallPopup and display it in a floating window with DisplayPopup. This last option is useful to see what is happening in various situations when the window partially overlaps the chart, and you can click on it when coming from the area of tracing and the rest of the main window.

    It seems to me the system honors the cursor style when, within a Panel (perhaps because in this area, there are controls that could be exploited on, who knows?) while is shows the default cursor elsewhere.

    Since when the popup appears the timer code is never executed and change of cursor is done by the operating system, I guess the only solution you must exclude the timer of the cursor when you use in the menu.

    (you will see that I changed from 32-bit configuration: I wanted to check if that changes behavior, but it works the same way)
