Shutdown abort

whats the worst thing that can happen when you kill oracle procee kill -9 or do shutdown abort ?
will oracle always get away with instance recovery ?
or it could corrupt redo log?
will there be need for recovery or restore?

whats the worst thing that can happen when you kill oracle procee kill -9 or do shutdown abort ?Database will shut down in inconsistent state and in next startup it need the instance recovery which is done automatically by SMON process.
will oracle always get away with instance recovery ?
or it could corrupt redo log? What you do mean by this line? Not clear to me what you want to ask
will there be need for recovery or restore?No need to restore and recovery is required in case of instance crash.

  • Loss of all controlfile,database is automatic shutdown abort?

    Your database is configured in NOARCHIVELOG mode. All the control files have been lost due to a hard disk failure but the data files are not lost. You have the closed whole database backup available to you. Which two statements are true in this scenario? (Choose two.)
    A) The instance aborts.
    B) The database cannot be recovered.
    C) The database can be recovered by restoring the control files from the backup.
    D) The database remains opened and you have to shut it down with the ABORT option.
    E) The database can be restored till the point of the last closed whole database backup.

    why,loss of all controlfile,the database not abort?

    Its only when the process terminates that the locks are released and file is actually deleted at operating system level.I concur!
    This behavior is *NIX only.
    Windows explicitly prevents open files from being deleted.

  • SHUTDOWN ABORT in ORACLE 10g

    Hi,
    I wrote a procedure to be run before reinstalling a database. As I am not interested in rolling back, or waiting for transactions to finish, I am using SHUTDOWN ABORT to drop users. Everything works well in ORACLE 9i but it cannot restart in 10g - error:
    ORA-12514: TNS:listener does not currently know of service requested in connect
    descriptor.
    The procedure looks like:
    SHUTDOWN ABORT
    STARTUP RESTRICT
    declare
    cursor cnt_usr is
    Select username from dba_users where username in (....some user names);
    str_cmd varchar2(400):='';
    begin
    FOR usr IN cnt_usr LOOP
    BEGIN
    str_cmd := 'DROP USER '|| usr.username || ' CASCADE ' ;
    dbms_output.put_line ('Executing: '|| str_cmd);
    EXECUTE IMMEDIATE str_cmd;
    EXCEPTION
    WHEN OTHERS THEN str_cmd := ' ';
    END;
    END LOOP;
    end;
    ALTER SYSTEM DISABLE RESTRICTED SESSION;
    exit;
    Any idea what may cause the error?
    Thank you
    Dan

    > You do know that Abort means to kill the database.
    Incorrect. It simply means that the database is shutdown in an inconsistent state - i.e. with "open" transactions and thus "dirty" data.
    However, Oracle is designed as a very robust database and this is not a problem. It simply gets the database into a consistent state again on the next startup.
    The risk is that something or someone interferes (mucks up) Oracle data files before the next db start - without the redo logs for example, the instance will have a hard time trying to recover the database and get it into a consistent state.
    The danger is thus not Oracle, but the Idiot Factor one tends to get with cowboy-type administrators.
    What is questionable though is the OP's script that requires the database to be shutdown and started up for a series of drop schemas. That is using a Very Large Hammer to drive in a Very Small Nail. It is a total overkill - not too mention impacting database availability.. And I do not think that our environment is so special/unique that it the exception to measure Oracle instance uptime in 1000's of hours.

  • How to startup database after shutdown abort

    Hi.
    I had a havy load transaction, coudn't kill, so I run shutdown abort,
    now I can't open database, that is massage I get:
    "ORA-16038: log 3 sequence# 52 cannot be archived
    ORA-19809: limit exceeded for recovery files
    ORA-00312: online log 3 thread 1:

    '/u01/app/oracle/flash_recovery_area/ORCL/onlinelog/o1_mf_3_48fpv95v_.log'
    What to do?

    Upss sorry:
    Check your flashrecovery area directory, it's full and your redo logs cannot be archived
    release the space..

  • Can a "shutdown abort" cause a fractured block?

    Hey there, simple question: Can a "shutdown abort" cause a fractured block?
    I'm currently doing some postmortem work on an old DB (EBS R12 OBA) installation and what might lead to a fractured block. It appears that once a fractured block is detected, Oracle Support automatically shuffles the issue off as a "serious issue within the OS/HW layer". I suppose as a DBA this means they can wash their hands of the issue and pass it on to someone else.
    So far it appears that an OS level app could compromise the write of logical blocks to OS blocks. It also appears that logical volume configuration (pertaining to an older AIX install) could lead to fractured blocks. Yet another article indicates that an HBA I/O error could lead to this issue. And of course file-system corruption.
    But...going back to the original question, can a shutdown abort on a database introduce a fractured block?

    It cannot. A shutdown abort or any abnormal termination means that active transactions are terminated without COMMIT or ROLLBACK. When you start the database after a SHUTDOWN ABORT or any other abnormal termination, Oracle says the active transactions failed and rolls them back. You will be left with the database in a consistent state as if those active transactions never occurred. I suppose you could say that until recovery is complete the block could be in a fractured state meaning that the contents could be inconsistent. But once the database is opened, the block is consistent and not fractured.
    HTH,
    Brian

    ALTER DATABASE COMMIT TO SWITCHOVER TO PHYSICAL STANDBY;

    But I didn't notice this "shutdown abort" when using 11.2.0.1.
    The same happens if at the beginning I remain in sqlplus sesison and try to run "startup mount"
    Is this expected?
    Thanks in advance,
    Gianluca

    If you use IMMEDIATE, an ABORT will be performed anyway as of 11.2.0.2 and you would see the following in the alert
    Performing implicit shutdown abort due to switchover to physical standby
    Shutting down instance (abort)
    So the answer is Yes.
    You can confirm this yourself by reviewing :

  • If shutdown immediate hangs database waits one hour for shutdown abort

    we have schedules cold backup for our 11g database on redhat 5.3.
    there is a shell script written with shutdown immediate command.
    If database hangs during shutdown immediate database waits one hour for auto shutdown abort.
    but this happens once or twice in a month
    can we do this auto shutdown abort earlier than one hour ??

    user13376823 wrote:
    we have schedules cold backup for our 11g database on redhat 5.3.
    Since you're shutting down the database for cold backup so ensure it should be shutdown properly by shutdown or shutdown immediate cmd not by abort cmd.
    Consistent backup:-
    A backup taken when the database is mounted (but not open) after a normal shutdown. The checkpoint SCNs in the datafile headers match the header information in the control file. None of the datafiles has changes beyond its checkpoint. Consistent backups can be restored without recovery.

  • Running shutdown abort

    When calling shutdown immediate and it lasts long
    because of rolling back some transaction, I call
    shutdown abort and start the instance, the crash recovery
    succeeds, is there any reason for shutting down normal
    again to last long too (there are no transactions to roll back)?

    Hi,
    any reason for shutting down normal do you mean shutdown normalWhen shutting down normal, Oracle waits for connected users to willingly disconnect (you can kill the sessions too though). Check if you've gor jobs running (DBA_JOBS_RUNNING) because they 'connect' to the database in order to run. This could be the reason why it takes a long time.
    For example if I bounce one of my main DBs, once it's open, at least 5 jobs will start running. If I issue shutdown normal it'll wait for these job to finish their tasks.
    Regards,

    I get a popup window on shutdown asking if I want to abort installation. I don't know what program is trying to install. But that generally stops the shutdown from completing. How do I find what application is being installed, and eliminate it?
    Running 10.10.2 on Macbook pro

    This has been going on for a while, I have no idea what it might be. The window does not state what is trying to be installed. Aborting the installation sometimes results in a shutdown, but also can block the shutdown, so I get a blank screen with the cursor - no spinning wheel.
    I just looked at the activity monitor, but have no idea how to read that. The following is just an example of part of what it shows.

  • Detect and Prevent SHUTDOWN ABORT

    Hello all,
    Is there any way to pre-detect the database when (for some reason) it is about to shutdown with the abort option?
    My concern, is whether there exist any way that can be used to notify the user (even the sysdba) that such event happened

    Hello back,
    This is what I've found the day the db went down, and the trigger was not fired

    I just thought, that "ringing a bell" when the db goes down would have been a solution while looking at the source
    cousing the error.

  • Abort 옵션으로 shutdown 했는데요...

    어떤 사용자가 대용량 DB작업을 걸고 있었는데..
    DB를 내릴필요가 있어 shutdown immediate명령을 내렸는데.. 도무지 내려가질 않더군요.
    그래서 할수 없이 shutdown abort로 내리고 다시 startup 시켰는데..
    여러개의 oracle 프로세스가 엄청난 양의 disk io를 발생시켜 전체 DB속도가 매우 느려졌습니다.
    도대체 오라클이 무슨 일을 하고 있는거죠?
    그리고 이런 현상을 방지하는 방법은 없는가요?
    - 사용환경 -
    IBM AIX 5.3
    Oracle 10g (10.2.0.2)

    shutdown immediate는 세션을 클리어시키고 트랜잭션을 rollback 시키고
    redo log에 있는 commit했으나 datafile에 쓰지 못한 데이터를 datafile에
    다시 쓰는 작업을 합니다. checkpoint도 찍고 내리겠죠.
    그런데 그 량이 많다면 내릴 때에 오래 걸립니다.
    하지만 shutdown abort로 내렸다고 할지라도 메모리를 빠르게 클리어시키기는
    하나 open을 시키면 instance recovery를 수행해야 하기 때문에 트랜잭션이
    있던 테이블은 undo에서 원본 데이터를 datafile에 적용하는 rollback을 해야
    하므로 lock이 걸립니다.
    오라클 데이터베이스에서 disk i/o가 일어났다는 것은 사용자의 쿼리가
    수행되어야만 일어나겠죠. 그러므로 사용자 쿼리가 어떤 것인지를
    wait event는 어떤 것인지를 알 필요가 있습니다.
    그렇다면 세션이 무슨 일을 하는지 알고자 하려면 아래 제가 정리한 것을
    참고하시길 바랍니다.
    10.2.0.2 버젼이군요.
    ADDM의 snapsoht을 수행하셨는지요?
    아니면 statspack 이라두요. 만약 그것이 있다면
    abort로 내리기 전에 문제가 생겼던 쿼리를 알 수
    있습니다.
    1. 단순히 어떤 작업을 하는지에 대해서 확인
    (1) A창에서 sh유저에 접속해서 조회
    SQL> select count(*) from sales, sales, products;
    (2) 아래 쿼리를 수행해서 ACTIVE SESSION을 확인
    ## s.sql ==> Active 유저에 대한 점검
    col machine for a15 trunc
    col username for a10
    col program for a15 trunc
    col status for a10
    col action format a10
    set lines 150
    select b.spid as unixpid, a.sid, a.serial#,a.username,a.program,a.machine,a.action,
    a.status,to_char(a.logon_time,'yyyymmdd hh24miss') as CONN_TIME, a.sql_hash_value
    from v$session a,v$process b
    where a.paddr = b.addr
    and a.status = 'ACTIVE'
    and a.type <> 'BACKGROUND'
    order by CONN_TIME;
    col machine for a15 trunc
    col username for a10
    col program for a15 trunc
    col status for a10
    col action format a10
    set lines 150
    select b.spid as unixpid, a.sid, a.serial#,a.username,a.program,a.machine,a.action,
    a.status,to_char(a.logon_time,'yyyymmdd hh24miss') as CONN_TIME, a.sql_hash_value
    from v$session a,v$process b
    where a.paddr = b.addr
    and a.status = 'ACTIVE'
    and a.type <> 'BACKGROUND'
    order by CONN_TIME;
    UNIXPID SID SERIAL# USERNAME PROGRAM MACHINE ACTION STATUS CONN_TIME SQL_HASH_VALUE

    2127 10 103 SYS sqlplus@rac2 (T rac2 ACTIVE 20060929 210821 1484184969
    (3) sidsql.sql 을 수행해서 현재 active session이 어떤 작업을 하는지 확인
    해당 쿼리가 나옵니다.
    ## sidsql.sql ==> sid 별 유저가 수행하는 쿼리문 추출
    set pages 40
    col program for a25
    col username for a10
    col machine for a15
    col module for a25
    col spid for a6
    col sid for 99999
    select a.username,a.program,a.machine,a.module,b.spid,a.sid,a.serial#,a.status,
    c.sql_text
    from v$session a,
    v$process b,
    v$sql c
    where a.sid = '&sid'
    and b.addr = a.paddr
    and a.sql_hash_value = c.hash_value(+)
    and a.sql_address = c.address(+);
    Enter value for sid: 9
    old 6: where a.sid = '&sid'
    new 6: where a.sid = '9'
    USERNAME PROGRAM MACHINE MODULE SPID SID SERIAL# STATUS
    SQL_TEXT
    SH sqlplus@rac2 (TNS V1-V3) rac2 SQL*Plus 2083 9 23 ACTIVE
    select count(*) from sales, sales, products
    2. wait event를 조사해서 waiting을 하고 있는 세션의 쿼리확인
    (1) wait event를 조회하는 쿼리 수행
    # wait.sql
    set timing off
    col user format a8
    col event format a20
    col sid_serial format a10
    col wait format 99999
    col program format a8 trunc
    col machine format a8
    set linesize 250
    col p1_val format a15 heading 'P1'
    col p2_val format a15 heading 'P2'
    col p3_val format a15 heading 'P3'
    prompt Session Informatiln
    select /*+ no_merge */ b.username "user", p.spid, a.sid||':'||b.serial# sid_serial, a.event,a.p1text||':'||a.p1 p1_val,
    a.p2text||':'||a.p2 p2_val , a.p3text||':'||a.p3 p3_val,
    -- a.seconds_in_wait wait,
    b.program, b.sql_hash_value
    from v$session_wait a, v$session b, v$process p
    where a.sid > 6 and a.event not like '%Net%'
    and p.ADDR=b.paddr
    and a.event not like '%timer%'
    and a.event not like '%ipc%'
    and a.event not like '%virtual%'
    and a.event not like '%slave wait%'
    and a.event not like '%wakeup time manager%'
    and a.sid = b.sid
    order by logon_time
    user SPID SID_SERIAL EVENT P1 P2 P3 PROGRAM SQL_HASH_VALUE
    SH 2083 9:23 direct path read file number:52 first dba:9418 block cnt:1 sqlplus@ 3635133102
    (2) sql_hash_value값을 통해서 쿼리점검
    - 위 결과에서 sql_hash_value값을 넣어주면 해당 세션이 어떤 작업을 하는지
    보여줌
    ## sidhashsql.sql
    set pages 1000
    col sql_text format a120
    select sql_text from v$sqltext_with_newlines
    where hash_value=&hash_value order by piece;
    Enter value for hash_value: 3635133102
    old 2: where hash_value=&hash_value order by piece
    new 2: where hash_value=3635133102 order by piece
    SQL_TEXT
    select count(*) from sales, sales, products
    3. oradebug를 이용해서 해당 세션에 대한 10046 trace event걸기..
    (1) active session을 위에서 제시했던 s.sql을 통해서 확인
    - 위에 있으므로 생략
    (2) oradebug로 세션에 대한 10046 트레이스 이벤트를 걸음
    - 아래에서 UNIXPID가 2083 으로 나왔음. 즉 ps -ef|grep ora 를 수행했을 때에
    ora9i 2083 2052 92 21:05 ? 00:07:52 oraclePROD (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))
    로 나오는 OS프로세스 ID인 2083을 말함
    만악 OS에서 top을 통해서 오라클 프로세스가 top에 있다면 그 세션에 대해서
    아래와 같이 oradebug를 수행하면 그 세션이 무엇을 하는지 알아내기 편합니다.
    SQL> @s

  • Shutdown hangs after drop column

    Hi,
    We were trying to drop column on a very big table, after that we cancelled that operation, and given shutdown immediate command.
    Now shutdown is taking too much time, going on from last 9 hours.....
    We want to start the database, what can be the best possible solution.
    Shutdown abort and startup will help ?
    Thanks
    Dilipkumar Patel.

    We were trying to drop column on a very big table, after that we cancelled that operation, and given shutdown immediate command.I guess SMON was doing rollback the transaction when you cancelled the operation. Since it was a big table, it was taking lot of time.
    Can you check the alter log is there any error or info msg in it?
    I am afraid if you give shutdown abort, may cause serious issues.
    Before you execute 'shutdown abort', make sure you have good backup, in case of recovery.
