How to find what archivelogs are needed for recovery

From Hemants sir's blog:
http://hemantoracledba.blogspot.com/2010/03/misinterpreting-restore-database.html
"You can query V$ARCHIVED_LOG for FIRST_CHANGE# and FIRST_TIME besides SEQUENCE#. That way, you can match SCN (FIRST_CHANGE#), Time and Sequence to determine which ArchiveLogs are need. The RMAN LIST BACKUP command shows you the Checkpoint SCN for all datafiles in a backup, so you need ArchiveLogs from the point of the earliest Checkpoint SCN in that backup set."
How can i find the earliest checkpoint SCN from the backupsets?
Any queries to find the earliest SCN in backupset(RC views)?
Edited by: user9097501 on Aug 10, 2010 6:38 AM

If i have to refresh the database from the backup of 9-AUG so the earliest SCN from where recovery would be needed is 60279026593 ?

  • Parental Controls - How do I find what apps are starting for an account?

    I turned on Parental Controls for my kids and when they log into their accounts they get a series of dialogs saying "You don't have permission to run <APP>, with Done, Always Allow and Allow Once buttons. Things like GoogleUpdater. None of these apps are in their startup list in System Preferences. How can I find what apps are set to startup for each account?
    - Thanks

    Here's a tip from another user that may help you:
    "I was running into the same problem trying to find apps for my daughters Iphone 3g running 4.2.1.  What I did was go to the Itunes store through Itunes on my PC, and then went to the bottom of the main page and clicked "Browse." On the browse page I selected, App Store, Games (category), Kids (subcategory), and then a list of apps appears below. 
    I sorted by date (oldest to newest) by right-clicking next to "price" and choosing "release date" on the menu that pops up. The date created field will then be showing, which you can click on to sort newest to oldest or oldest to newest.  I downloaded a bunch of free apps starting from the oldest (by name - you don't have much else to go on).  Of the 30 or so I added to my Itunes, about 27 of them were compatible with 4.2.1. 
    This is defintely not a perfect way of finding apps, but after spending a lot of time searching for a better way this was the best I could come up with."

    I would like to patch some of them if needed, but I don't know how to find patches are needed?
    tnx

    Hi,
    The following methods will help to know what are the patches installed at your ORACLE HOME
    1) opatch lsinv -bugs_fixed
    This option will give description of installed patches as below, but the opatch version should be higher than
    10.2.0.4.5 for version 10.2 ORACLE_HOMEs
    $ opatch lsinv -bugs_fixed
    8576156 8833280 Tue Feb 09 16:54:18 MST 2010 DATABASE PSU 10.2.0.4.3 (INCLUDES CPUJUL2009)
    8833280 8833280 Tue Feb 09 16:54:18 MST 2010 DATABASE PSU 10.2.0.4.4 (INCLUDES CPUOCT2009)
    2) select substr(action_time,1,30) action_time,
    substr(id,1,10) id,
    substr(action,1,10) action,
    substr(version,1,8) version,
    substr(BUNDLE_SERIES,1,6) bundle,
    substr(comments,1,20) comments
    from registry$history;
    This option will work when post installation has been performed for that patch

  • What patches are needed for OCS R1 singlebox Windows installation

    Hi there,
    I'm trying to install OCS R1 on Windows 2000 server and I wanted to know if I need any patch to perform the installation.
    I'm following the Note 221812.1 and according to it I have created email accounts as mailadmin (System Administrator) and now I should apply the patch 2606325, but I don't know if this is required for Windows. It probably is, because I skip this step and test the mail system by sending mails between the accounts already created and I get a message which says that: an error has occurred at attempting to send the message.
    I don't know if this is due to the fact that I haven't applied the patch or due to something else...
    I would appreciate any help.
    Best regards,
    Jorge

    I tried to check out that note of yours, i think it no longer exists, the same goes for the patch number.
    Anyway from my linux install as far as the installation goes, there was no need for patches ocs installs without them. However if you want to use something like workflow for files, then you need a few patches.
    Firstly you need to patch which is applied after your workflow installation - i cannot rememeber its number, but you should find it in eithr the files admin guide or files release notes for 9.0.3.
    In addition to that, when you install workflow, you also need to add a few languages, which if you do not with result in your workflow/files integration failing.

  • What claims are needed for search?

    We have a SP 2013 search system where it searches a different sharepoint farm. Before with NTLM, we were able to get those results.  After implementing single sign on with Ping Federate, we are unable to get search results from that other
    system. We suspected at first that we needed the group memberships to be added to the claims, which we tried. But still nothing. Does anyone know what claims would be needed in this scenario? We currently get primarysid, upn, windowsaccountname, and now Groups.

    Hi Scott,
    You may check if "Windows authentication" has enabled for your web application for this issue, here are some useful posts about this topic, you can take a look.
    "If you are using claims-based authentication, make sure that Windows authentication is enabled on any Web applications to be crawled."

    I just installed Flip 4 Mac Studio Pro so that I can make wmv files in different sizes. It works in 340x240 and 480x360, but freezes up when I choose the preset 384x288. Are there other settings that need to be changed to make this work. I thought this version of Flip would allow me to do most anything.
    I'm exporting a short 4 min sequence from FCP using Quicktime conversion.

    This will give you the instructions on how to set it up step by step.

  • What files are needed for backup

    Hello all,
    Our database stopped working because of a mistake and we've lost lots of our control files and configuration files.
    On the other hand there are 5 oracle_homes in our system! So we decided to uninstall Oracle and install a clean version and restore our data, tables, triggers, functions and ... to it.
    We have many rman level 0 and 1 backups since 2 months ago and the size of each level 0 backup is around 1.8 GB.
    But I am new to Oracle, so please let me know which files I need to keep from our current Oracle before uninstalling it and how I can restore backups to the new oracle (probably I will install it in a new drive not in D:/ again and with a new SID maybe). Also please let me know which version I should install? (Desktop Class or Server Class) We have some applications on our own laptops which connect to server and retrieve/insert data from/into oracle database on the server.
    Our current database does not mount and open because of the problems I mentioned above.
    Our server is: Windows Server 2008
    Oracle Version: 11g
    The scrips the we used to create rman backups are:
    echo database backup, level 1
    echo %DATE%
    echo %TIME%
    set datetimef=%date:~-4%_%date:~4,2%_%date:~7,2%_%time:~0,2%_%time:~3,2%_%time:~6,2%
    echo %datetimef%
    rman target / @F:\backup1.txt LOG F:\database-backup\rman-logs\%datetimef%.txt
    copy F:\database-backup\rman-logs\%datetimef%.txt F:\database-backup\rman-logs\current-log.txt
    and
    echo database backup, level 0
    echo %DATE%
    echo %TIME%
    set datetimef=%date:~-4%_%date:~4,2%_%date:~7,2%_%time:~0,2%_%time:~3,2%_%time:~6,2%
    echo %datetimef%
    rman target / @F:\backup0.txt LOG F:\database-backup\rman-logs\%datetimef%.txt
    copy F:\database-backup\rman-logs\%datetimef%.txt F:\database-backup\rman-logs\current-log.txt
    Thanks

    RMAN's BACKUP command supports backing up the following types of files:
    Database files, including datafiles, control files, and the server parameter file (SPFILE)
    Archived redo logs
    Other backups created by RMAN, including such as datafile and control file image copies, and backup sets containing SPFILEs, control files, datafiles and archived logs

  • Database Integrity check failed, how to find an un-corrupted backup for recovery

    I got database integrity check task that runs weekly. The job ran March 23rd but failed on March 30th. We have identified that there is a corruption in database and now the task is to restore it from backup (with data loss). We have database backup running
    every-night and I need to know how can I find which is the latest backup that's not corrupted.
    The MSDN documentation says "RESTORE VERIFYONLY" command does not verify whether the structure of the data contained within the backup set is correct. Does it mean the restore command will not able to detect corruption in the database and I just
    need to restore each of the backs starting from the latest to see if integrity check fails after restore ? OR RESTORE VERIFYONLY will confirm if the database is un-corrupted ?

    As the documentation suggests, RESTORE VERIFYONLY checks the structure of the backup but not the database itself.  You'll need to restore the backup to check the database consistency.

  • How do I determine what xtras are needed?

    From the searching I have done it appears that xtras equired are mostly trial-and-error.
    Is there an efficient way to determine what xtras are needed for each lindividual movie?
    My programs are divided into a series of sequential movies.  At the end of each movie
    there is a goto statement to launch the next movie.  Does that require me to determine
    xtras for each separate movie? 
    In a perfect world there would be a way for Director to search a  folder for and present an aggregate list of all xtras required for that set of movies.
    If no such method exists, what is the recommended hunt and peck system?

    Thanks for the response, rduane.  But I refer to the procedures as a bit random for the reasons you mentioned in your explanation.  For example, you stated that, "Director will normally add all of the Xtras that you need to each movie as you build it".  And, yes, I know that it does add some automatically.  But, if Director really does "add all of the xtras that you need to each movie as it is built", how could I ever jump to one that is missing a needed xtra?  If it needs it, why wasn't it added when it was built?
    So, that's the reason I mentioned "trial and error", and "hunt and peck".  The system is not reliable in its handling of xtras, or which ones are needed where.  I am familiar with workarounds such as going to each movie and selecting Modify>Movies>Xtras to see which ones Director has added,  But that is all it tells you.  It does not tell you if it has added all the xtras "needed".  And when the error message comes up, it does name the missing xtra, but not which movie needs it.  So, one has to go find the named xtra and copy it over to the Xtras folder. 
    At least, that's what I do to fix it.  But I asked the question because I wanted to know if Xtras handling itself is unreliable, or if I'm doing something incorrectly.

  • Which archivelogs are required for restoring database

    I'm moving to RMAN direct to tape backups (via Netbackup). I'm hoping someone can clarify for me which archivelogs are needed for restoring/recovering a RMAN "hot" backup.
    I will have two tape pools with different retention periods:
    - standard (kept for 2 months)
    - long term (kept for 7 years)
    I plan to backup as follows:
    - archivelogs every 15 mins direct to the standard pool
    - daily backups to the standard pool
    - monthend backups to the long term pool
    Month ends will either be a full or a full plus a cumulative (level 2) (depending on the weekday that month end falls on).
    The bit I'm concerned about is archivelogs. After 2 months they will be expired on tape. But do I need archive logs in order to restore the month end backups?
    At the moment I record the SCN before the backup begins and after it finishes (retrieved via select first_change# first_scn from v$log where status = 'CURRENT'). Before recording the post-backup SCN, I force a logfile switch.
    For clones, I always restore to the post-backup SCN that I previously recorded (rather than using the tag I associated with the backup).
    So a few questions related to restoring after the 2 month window:
    - do I need the archivelogs created during the timespan of the backup ran in order to restore to the post-backup SCN?
    - If so, is just backing up these archivelogs (to the long term pool) by specifying the range of pre-backup SCN to post-backup SCN sufficient or are additional archivelogs likely to be required?
    - if I restore the database and don't specify an SCN but just specify the tag used at the time of the backup, will archive logs be required at all? In this case what would be the state of the restored database - would it be as it was at the beginning or at the end of the backup?

    Hi user4835675,
    do I need the archivelogs created during the timespan of the backup ran in order to restore to the post-backup SCN?Yes.
    If so, is just backing up these archivelogs (to the long term pool) by specifying the range of pre-backup SCN to post-backup SCN sufficient or are additional
    archivelogs likely to be required?Can you do a skip of the daily backup schedule duing the monthend backups run and run the "archivelogs every 15 mins" job to the long term pool?
    Or temporarily stop the "archivelogs every 15 mins" job during the monthend job and run the monthend backup with the "backup database plus archivelog" clause?
    if I restore the database and don't specify an SCN but just specify the tag used at the time of the backup, will archive logs be required at all?Yes, you need archivelogs to recover the datafiles to a consistent state.
    In this case what would be the state of the restored database - would it be as it was at the beginning or at the end of the backup?You can only restore to a point in time which past the end of the backup.

  • Determining what views are created for certain structure

    Hi!
    I need to create some views to structure in Development system as it is done in Production system already. It is something like manual transfer of structure and it's views from Production to Developement system (special case).
    My question is this: how to determine what views are created for certain structure?
    Will reward,
    Mindaugas

    Use 'Where-used' list for that structure.
    Go to SE11.
    Enter the structure name.
    click on the Where-used list button in the toolbar.
    Select the applicable options. (In your case 'Views')
