RMAN does not delete obsolete files in a reliable way

Hello experts RMAN,

I have 11.2.0.1.0 on Windows Server 2003

This instance IS in ArchiveLog mode. Do NOT use the catalogue

Recently, I noticed inconsistent behavior of RMAN to delete obsolete backup sets.

Let me give you an example: for months, I had the window of recovery set to 12 days.

RMAN > view the retention policy.
CONFIGURE RETENTION POLICY TO RECOVERY OF 12 DAYS WINDOW;

Yesterday, 3/27 report obsolete showed this file:

20270 23 March 12 backup set
Total backup, 20270 F:\ORACLE\FLASH_RECOVERY_AREA\PBS March 23, 12
\BACKUPSET\2012_03_23\O1_MF_ANNNN_TAG20120323T050002_7PRLFJ36_. BKP

Today, 3/28, ran my work of simple deletion: delete NOPROMPT obsolete;

Now, 2012_03_23\O1_MF_ANNNN_TAG20120323T050002_7PRLFJ36_. BKP no longer exists.

Not all the files backup for 3/23 have been removed, only a small number.

But why is any file 3/23 get deleted when the recovery window is 12 days?

Of course, I'm afraid that my RMAN backups is perhaps not valid.

Is that what someone did this experiment with RMAN on Windows?

Thanks for all the ideas. John

BACKUP VALIDATE... will not check your backups already taken.
To do this, you need to run VALIDATE BACKUPSET or RESTORE VALIDATE that will search all the backup files needed to do a restore.

Restoration of points must be created manually, so it's ok your results, if you have not created a.

    Nearby: what is now the tag for the code? The former seems to not work...

    I found why RMAN took so long backups: in 15.07.2013 I have excluded a tablespace backups because it was non-productive. But RMAN simply leaves the last backup where this tablespace was because it must ensure that. So I deleted #ve this backup manually sets and all the others after that, on retention policy becomes obsolete, and I was able to remove this one!

    Thanks for your great help!

  • Does not delete the files off the SD through FileConnection

    As part of the application that is being developed, we try to make the dynamic files.

    When you run the update code pluck us files that are up to date and try to update by deleting everything first and then download them again.  Here is the code that we strive to use

    try
                            {
                                conn2 = (FileConnection) Connector.open("file:///SDCard/MeetApp" + filename.substring(0,(filename.length()-1)) + ".xml", Connector.READ);

                                                               if (conn2.exists())
                                                            {System.out.println(conn2.fileSize());
                                                                      conn2.close();
                                                                 conn2 = (FileConnection) Connector.open("file:///SDCard/MeetApp" + filename.substring(0,(filename.length()-1)) + ".xml",Connector.READ_WRITE);
                                                                       conn2.delete();
                                                                       conn2.close();
                                                                }else{System.out.println("No dice");}
                        }
                        catch(Exception e)
                        {

                        }

    However, the files will not erase.  I have triple checked the path names, they are correct.  However, every time that I ask him to find a file, it is said that there is not.

    Any ideas?

    I found the problem.  When I analyze the file type of an XML document, I get the word 'page' or 'active '.  There must be a space to share and across these words when they come from the XML document because they do not equate the string 'the page' unless you trim() them.  To be sure, I converted them to hashcode and now it works correctly.

    Hi all, I found the problem which has been much easier to fix that remove your App preferences.  Seems that there is conflict when you run two HDs in the machine which have the same "Volume UUID.  There is a problem running on Western Digital portable HDs.  Remove one of the two contradictory HDs and problem solved.

    Don't forget, when you delete the preferences of the application file you also REMOVE ALL YOUR ACTIONS!

  • New Mac, same disk external DRIVE for the library; does not see the files

    I reconnected my iTunes library from a disk external DRIVE to my new computer, but iTunes does not recognize my files of the ALAC instead, he goes to the cloud and plays music from Apple things. How can I listen to my files? All the files are there, the library is intact; I changed the path in iTunes. Without result. He always plays with the cloud.

    You do not change the path in iTunes.  Who does as it says which is tell iTunes where media files [new] store. You change the path you launch iTunes by holding down the option/alt key, while the application starts and then choose when prompted the iTunes Library.itl file in the iTunes folder you included if all goes well on the hard disk external.  If everything you have on the outside are media files, then you better head for your old computer fast and get the rest of the library there.  It's the rest of these files in the iTunes folder that make up the other half of the 'library' iTunes needs.

  • Why Firefox does not delete cookies by leaving to open tabs?

    Firefox does not delete cookies for the tabs that are left open when you quit the browser even with empty cookie options set. Cookies are only eligible for the tabs that are closed before leaving the browser. I do not understand how this could possibly be a design decision because it completely defeats the purpose of the privacy settings.

    Under Options > Privacy I enabled/selected, the following options.

    • Accept cookies (no "Exceptions... »)
    • Continue until the "closing of Firefox".
    • Clear history of Firefox closing
    • * Download history
    • * Cookies
    • * Active Logins
    • * Cache
    • * Data from the Web site offline

    These cookies are stored in session data.

    You can set the browser.sessionstore.privacy_level pref 2 (never) or 1 (no HTTPS, default in the Firefox 3 versions) on the topic: config page to disable the registration of cookies via session restore.
