Crash - recovery problem - ora-1113

Hi,
Because of the hardware problems, my database server has crashed. Database (8.1.7) works in archive log.
Before the crash, the last log switch seq# was 17173:
ARC2: Beginning to archive log# 12 seq# 17173
ARC2: Completed archiving log# 12 seq# 17173
After the crash I tried to open it, counting on automatic revovery. SMON started to do roll-forward etc., but suddenly got an error:
alter database open
ORA-1113 signalled during: alter database open ...
I tried to use until cancel recovery:
ALTER DATABASE RECOVER CONTINUE DEFAULT

ALTER DATABASE RECOVER CANCEL
ORA-1547 signalled during: ALTER DATABASE RECOVER CANCEL...
The problem is, that the redo-log seq# 17174 do not exists...
I do not understand, what happened, why the information couldn't be read from online redo logs if they exist...?
I had to do point-in-time recovery, now the database works OK, but still don't know why Oracle wanted to use log #17174? Any ideas?

The ORa-1113 error means that your Backup implementation ("Retrospect") does an ALTER TABLESPACE BEGIN BACKUP and END BACKUP for each tablespace.
In 8i, you would not have the "ALTER DATABASE END BACKUP" command. Nor the "ALTER DATABASE DATAFILE .. END BACKUP".
What you would do is :
1. Start the service.
2. Go to Windows command line prompt as the Administrator or account in the OS_DBA group (with the right ORACLE_SID, ORACLE_HOME and PATH)
3. sqlplus / as sysdba
4. startup mount -- or ALTER DATABASE MOUNT if it did get started but not mounted
5. ALTER TABLESPACE (tablespacename_that_was_in_backup_mode) END BACKUP ;
(if there were multiple tablespaces in backup mode, issue the END BACKUP for each one of them)
6. ALTER DATABASE OPEN ;
The other option to step 5 is the "RECOVER DATABASE" . Oracle may apply archivelogs to synchronise the datafiles back.

    You are certified but you don't know how to to recover a database with corrupt redo logs? There you have my problem with certificates: they don't tell you jack about the true knowledge of the DBA and his problem solving skills. (or is this exactly what you are saying with "book knowledge"? I am no native English speaker, so I might have misunderstood).
    Just enter your ORA-error in a metalink search and you will find notes that explain exactly what to do (the how-to's you mention ;))

  • Crash recovery of productive db very slow

    We had to shutdown a productive database with db2_kill, because it couldn't be stopped normally and had problem with a full FAILARCHPATH (After TSM server had problems, the archiving to TSM has not been successfully any more, even after TSM Server was up again: We had this problems before....)
    The crash recovery takes very long.  Sometimes even db2 list utilities <show details> seems to hang.
    With db2pd -everything  I can see the progress of the crash recovery:
    Database Partition 0 -- Database PC1 -- Active -- Up 0 days 01:57:14 -- Date 05/07/2008 11:34:59
    Recovery:

    So the db has now finished approx 1/3 of the bytes of the forward phase and then also have the backward phase!
    In the db2diag.log there are no more entries after beginning of the crash recovery of 09:38.
    We have move one logfile from the FAILARCHPATH directory (which was 100% full) to a different directory  to be sure, that the slow crash recovery has nothing to do with the full FAILARCHPATH.
    The log_dir directory  has 20 logfiles (LOGPRIMARY+ LOGSECOND) in it  (more could not be allocated there because the log_dir is sized according to the LOG-Parameters)
    Parameter UTIL_HEAP_SZ = 150.000
    Does anybody have an idea, why the crash recovery is so slow ?
    Kind regards,
    Uta

    Hello Ralph,
    the needed logfiles were all there and we didn't need to restore any logfiles from tsm (the "active" logfiles, which are needed for crash recovery should always reside in the log_dir...)
    At  2008-05-07-14.17.07.357544   crash recovery was completed successfully.
    At 2008-05-07-13.56.41.297552   the db has started  archiving to tsm again:
    ADM1844I  Started archive for log file "S0003329.LOG".
    According to dba collegues the crash recovery were  only 50 % finished and then suddenly  everything was finished. Since the "db2 list utilities" takes forward and backward phase into account for percentage, I assume that the backward phase  was very fast.
    The dba collegues  have also recognized, that in the log_dir there were logfiles which were archived to tsm already. So they moved them out of the log_dir, and additional logfiles could be allocated (Before no add. logfile could be allocated). I couldn't say, if this was the reason, why the recovery was finished then afterwards.
    The only problem is, that the database doesn't want to archive  Logfiles  S0003329- S0003350. Strange  is also, that logfile 3329 was archived to the FAILARCHPATH yesterday successfully,

    and this was none of the logfiles, which the collegue moved out of log_dir.
    Has anybody  seen the situation  that the db couldn't  archive from failarchpath to TSM after failure. We don't want  to control every FAILARCHPATH after TSM-Failures....

  • Crash recovery: recreating invalid indexes

    I want to discuss a phaenomen, which we often have saw during crash recoveries:
    The "startsap db" is hanging, because after the crash recocvery itself is completed (according to db2diag.log), the connection to the database ist still hanging because the database recreate invalid indexes.
    sf503:db2p02 10%  db2 list utilities
    ID                               = 2
    Type                             = RESTART RECREATE INDEX
    Database Name                    = P02
    Partition Number                 = 0
    Description                      = Recreating Invalid Index Objects
    Start Time                       = 05/08/2007 09:37:42.721072
    Sometimes this can take up to 25 minutes until this is finished and the connect is finished.
    The strange thing is:
    If a 2. connection to the database is made during "recreating indexes", this 2. connection is successfull and selects from t000 are successfull.
    So, it is possible to execute "startsap r3" while the first connection is still blocked with recreating indexes.
    I don't understand this behaviour:
    - If the database really needs the recreation of invalid index objects  for sucessfull database operation, then it should block ALL connections and not only the first one.
    - If it's not urgently necessary, the database should done the recreating indexes in background and not block the first connection.
    Also in the Recovery& High Availibility IBM Handbook I have nothing found about the "recreating  invalid index objects"-feature.
    Kind regards
    Uta

    Hello Jens,
    thanks for the detailed answer!
    As you wrote, the only workarond with changing  db cfg parameter from "restart" to "access" needs some manual intervention if  we don't want to risk the limit of maximum dialog runtime. So actually we will leave it as it is. We have a workaround with starting sap in a second window, when  the crash recovery is finished according to db2diag.log and the 1. connection (startsap db) ist still recreating invalid  indexes.
    How can one determine the invalid indexes, who need recreation ?
    Joachim: we don't have a real problem at our site. Fortunatelly we have crash recoveries only in the rare cases of system crashes, etc. So we are lucky not to have it every day....
    Hopefully the behaviour will be changed  to background index recreation in some later DB release.

  • When occurs crash recovery,why use active online redo log not archived log?

    If current redo log had archived, but it's still 'ACTIVE'. As we all know, archived log is just an archived copy of the current redo log which is still 'ACTIVE', they have the same data. But why use active online redo log not archived log for crash recovery?(I think, if crash recovery can use archived log, then whether the online redo log is 'ACTIVE' or not, it can be overwritten)
    Quote:
    Re: v$log : How redo log file can have a status ACTIVE and be already archived?
    Hemant K Chitale
    If your instance crashes, Oracle attempts Instance Recovery -- reading from the Online Redo Logs. It doesn't need ArchiveLogs for Instance Recovery.
    TanelPoder
    Whether the log is already archived or not doesn't matter here, when the instance crashes, Oracle needs some blocks from that redolog. Archivelog is just an archived copy of the redolog, so you could use either the online or achive log for the recovery, it's the same data in there (Oracle reads the log/archivelog file header when it tries to use it for recovery and validates whether it contains the changes (RBA range) in it what it needs).

    John,
    Are you sure that the instance recovery (not the media recovery) would be using the archived redo logs? Since the only thing that would be lost is the isntance, there wouldn't be any archived redo log generated from the Current redo log and the previous archived redo logs, would be already checkpointed to the data file, IMHO archived redo logs won't participate in the instance recovery process. Yep, shall watch the video but tomorrow .
    Regards
    Aman....
    That's what I said. Or meant to say. If Oracle used archivelogs for instance recovery, it would not be possible to recover in noarchive log mode. So recovery relies exclusively on the online log.
    Sorry I wasted your time, I'll try to be less ambiguous in future

  • Unable to send crash/error problem report

    Hi There,
    I have recently noticed that when a program I am running either force quits on it's own or I have to manually force quit the program, I am unable to send crash/error problem report to Apple. This has happened for all my programs from Safari and iTunes to recently Microsoft Word. The crashing messed up my internet as I had to give up using Firefox (because it kept crashing and wouldn't send a report) so I downloaded Chrome.
    Yesterday, Microsoft Word had to force quit because I manually quit the program but it never closed. It kept running in the background at 192% under my operating processes. When I force quit Word, it gave me the option to report the problem or ignore it. I chose to send a report but once that Problem Report screen loaded, it would not let me send to Apple, stating "Your submission could not be submitted. Please try again later."
    I have tried numerous times since all to no avail. As I mentioned, this happens on a lot of programs lately and I don't know what to do to fix it. Below are the specs of my Macbook. I can copy the problem details, but is lengthy.
    Any help/feedback is greatly appreciated.

    Welcome to Apple Support Communities.
    Apple is apparently no longer accepting crash reports for 'Leopard' OS X 10.5.8.
    https://discussions.apple.com/message/17544781#17544781
    Typical disk-maintenance activities when crashes occur include using Verify, and Repair Permissions on your hard drive (probably labeled Macintosh HD), using Disk Utility.
    10% to 15% of hard-drive capacity is generally acknowledged as the minimum amount of free space needed for adequate performance.

  • "cache recovery" vs "crash recovery" ?

    Dear Friends ,
    Would anybody plz tell me the difference between "cache recovery" and "crash recovery" in oracle ?

    I search in google but dont get satisfactory answer ... ...Crash recovery is performed whenever their is instance failure (single instance or RAC)
    Crash recovery is done in two phase 1) Cache recovery 2) Transaction Recovery.
    So crash recovery includes cache recovery.
    Cache recovery means to apply redo log from log cache to the datafiles which may contain uncommitted transaction also.
    These uncommitted transactions should be rolled back during crash recovery, and hence in transaction recovery it applied undo for all such uncommitted transaction.

  • Crash recovery

    Hello,
    Who initiate the crash recovery? SMON process or any other process?
    In the ealier version of oracle (Oracle 7.3), it was instance recovery,
    Now in Oracle 9i there are two types of recovery one crash recovery and another is instance recovery.
    I want to know that whether in prior to Oracle 9i, there were two such recovery or only one?
    Thanks.

    crash recovery
    The automatic application of online redo records to a database after either a single-instance database crashes or all instances of an Oracle Real Applications Cluster configuration crash. Crash recovery only requires redo from the online logs: archived redo logs are not required.
    In crash recovery, an instance automatically recovers the database before opening it. In general, the first instance to open the database after a crash or SHUTDOWN ABORT automatically performs crash recovery.
    instance recovery
    In an Oracle Real Applications Cluster configuration, the application of redo data to an open database by an instance when this instance discovers that another instance has crashed.
    Hope it helps.

  • Crash recovery everytime starting an instance

    Is it normal that a crash recovery is started every time I start
    an Oracle instance on a WinNT 4.0 system.
    The xxxALRT.log file contains messages like this:
    alter database open
    Beginning crash recovery of 1 threads
    Thread recovery: start rolling forward thread 1
    and so on ...
    The database startup takes a long time but after that the db
    works normal.

    Oracle always does recovery processing on startup. If you
    shutdown abort your startup will take longer because there is
    more recovery processing that has to be done. Shutting down
    immediate takes longer because it performs clean up process so
    that when you startup not as much recovery processing is needed.

  • Crash recovery/ instance recovery

    Hi,
    How do oracle identifies crash recovery/ instance recovery

    Regards,
    Mathew

    Hi,
    >>But how do oracle identifies dabase is abnormally down and crash recovery is required?
    I think that the checkpoint information that is desynchronized in redo log files and datafiles. It is necessary understand what is a checkpoint and what the CKPT process do. A checkpoint is a moment in time when all the changes (dirty blocks) made in the database buffer cache are made to the data files. The checkpoint is performed by the CKPT process and it creates an entry in the control file to identify the point in the online redo log file from where the instance recovery should begin in case of an instance failure. One of the ways a checkpoint is initiated is by the data block writer (DBWR) process. The DBWR process initiates a checkpoint by writing all modified data blocks in the data buffers (dirty buffers) to the data files. After a checkpoint is performed, all committed transactions are written to the data files. If the instance were to crash at this point, only new transactions that occurred after this checkpoint would need to be applied to the database to enable a complete recovery. Therefore, the checkpoint process determines which transactions from the redo logs need to be applied to the database in the event of a failure and subsequent recovery.
    Cheers

  • Crash recovery for zones

    hi,
    What's the best way for crash recovery for zones?
    Thanks,
    Rosario

    there are some recipes using the snapshot feature of ZFS systems. I tried a solution for non ZFS filesystems:
    to backup:
    df -F nfs | sed "s/ .*//" > /tmp/excludes # this excludes NFS mounted filesystems
    find /$zonepath/$zonename -fstype lofs -prune 2> /dev/null | sed "s/^\/$zonepath\///">> /tmp/excludes # this exclude LOFS mounted filesystems
    echo "$zonename/root/proc" >> /tmp/excludes
    echo "$zonename/root/var/run" >> /tmp/excludes
    echo "$zonename/root/system/contract/all" >> /tmp/excludes
    echo "$zonename/root/system/contract/process" >> /tmp/excludes
    echo "$zonename/root/etc/mnttab" >> /tmp/excludes

    cd /$zonepath
    tar -EcfX /$somepath/$zonename.tar /tmp/excludes $zonename 2> /tmp/$zonename.err
    to restore:
    extract tar
    mkdir of all mount points
    mkdir for all dynamic data (i.e. $zonename/root/proc), assigning correct permissions&ownership

  • KT4 Ultra crashing/rebooting problems

    Hi all, I've been having computer crashing/rebooting problems when I play 3d games since I got this board. It can happen between 1-40 minutes during a game session and when the computer crashes, the screen would garble up and reboot along with the garbled screen until I cold boot it. I thought it was a heat problem at first but the cpu heat displays at between 34C-39C. Also, when I tried switching out the video card with an older one, the computer works fine during gameplay, and my newer video card ran fine on a friend's computer. Does anyone know of a way to fix this?
    System specs are:
    Motherboard: MSI KT4 Ultra
    CPU: AMD AthlonXP 2400
    Power: 300watt
    Ram: PC 2700 333mhz DDR 256MB
    Video: Gainward Geforce4 Ti4200 Power Pack Plus! Ultra 650 64MB
    Sound: Onboard
    Thanks

    by the sound of it try a bigger psu,antec enermax over 400 watts
    make sure fan on cards not loose
