  • Need advice on ORA-01578: ORACLE data block corrupted

    We have a development database server version- 10.2.0.3 with materialized views refresh as complete every morning. Yesterday we had a power failure and the server went down and database was shutdown unexpectedly.
    When we restarted the database after the server restarted, we found some of the datablocks got corrupted . Following were the exceptions that we saw in the alert.log.
    Errors in file /i01_01/app/oracle/product/10.2.0/db_1/admin/orcl9/bdump/orcl9_smon_7547.trc:

    ORACLE Instance orcl9 (pid = 8) - Error 1578 encountered while recovering transaction (9, 38) on object 54463
    I tried the following query to see the segment type.
    select owner, segment_name, segment_type from dba_extents where file_id =11 and 257712 between block_id and block_id + blocks - 1;
    OWNER
    SEGMENT_NAME
    SEGMENT_TYPE
    VISH
    INVENTORY_TXN
    TABLE
    where " INVENTORY_TXN " is a materialized view that was using the block that got corrupted. I can always recreate the MV by dropping and recreating it. Will it solve the problem???
    If not, how can I recover/repair the block.???
    Can anyone advice on this. Thanks very much in advance.

    To recover a corrupted block,the best way out is to use Blockrecover command of RMAN. So you would need RmAN backup to perform the operation.But first ypu you need to ensure that this is a persistent error or not? Is this error is coming repeatedly or just once it happened?
    About Blockrecover command,read here,

    Dera Guru's,
    In SAP i have following error in Oracle Database
    SQL error in the database when accessing a table
    "Database error text........: "ORA-01578: ORACLE data block corrupted (file #
    38, block # 72576) ORA-01110: data file 38:

    Thank you for your help and advice....

    Error: ORA-01578 (ORA-1578)
    Text: ORACLE data block corrupted (file # %s, block # %s)
    Cause: The data block indicated was corrupted, mostly due to software errors.
    Action: Try to restore the segment containing the block indicated. This
    may involve dropping the segment and recreating it. If there
    is a trace file, report the errors in it to your ORACLE
    representative.
    Do you already identify the object corrupted ?
    What kind of backup do you have ?

  • ORA-01578: ORACLE data block corrupted on tables in sysaux tablespace

    Dear Experts,
    From the alert log file we noticed data block corruptions on one of our datafiles. After further investigation, we realized that the corruptions were on 3 of the AWR related tables in the SYSAUX tablespace:
    1. WRH$_LIBRARYCACHE
    2. WRH$_TEMPSTATXS
    3. WRI$_ALERT_OUTSTANDING
    The bad news is that we may not have a valid rman backup to do the recovery due to the retention policy - RECOVERY WINDOW OF 2 DAYS. Since this is a development database with limited monitoring, we did not discover the corruption until 6 days later. The issue happened about 6 days ago (about Christmas time).
    So, what are our recovery options? Can someone advice? We are thinking about drop and recreate the 3 affected v$WR* tables, but not quite sure about the impact to the system if we drop and recreate the 3 objects. Did someone experience this type of recovery. If you did, what are your approaches?
    We are running oracle 10.2.0.3 version.
    I greatly appreciate your input and suggestion. Thanks!!!

    as long as you have a backup of ur database before christmas, you can use the " MAXDAYS " cmd to get ur backup working so long as you have not used delete obsolote....had a same sistuation....where i had a backup and trying to restore it ...kept saying no valid backup...after going thru some stuff...found the MAXDAYS cmd to use my backup...here is an example ...

  • Outbound oracle data into xml file

    Hi Odie,
    Your previous inputs for xml inbound was working fine, in the similar way now I need outbound the oracle apps data into .xml file format. For that I've written one sample script like this. I thought of making use of the utl_file option in Oracle apps.
    declare
    l_log_handle UTL_FILE.FILE_TYPE;
    l_log_name varchar2(50);
    l_path_2 varchar2(40);
    l_global_file varchar2(50);
    l_time number:=1;
    cursor cur1 is
    select xmltype(cursor(select * from fnd_menus where rownum <101)) a from dual;
    --select menu_id from fnd_menus where rownum<100;
    begin
    BEGIN
    SELECT DECODE (INSTR (VALUE, ','),
    0, VALUE,
    SUBSTR (VALUE, 1, (INSTR (VALUE, ',', 1)) - 1)
    INTO l_path_2
    FROM v$parameter
    WHERE NAME = 'utl_file_dir';
    EXCEPTION
    WHEN OTHERS THEN
    dbms_output.put_line('Error while getting Unix Path ' || SQLERRM);
    END;
    l_log_name := 'XGBIZ_'||TO_CHAR (SYSDATE, 'YYMMDD')||l_time;
    l_log_name := CONCAT(l_log_name,'.xml');
    l_global_file := l_log_name;
    l_log_handle := UTL_FILE.FOPEN(l_path_2,l_log_name,'W');
    for cur2 in cur1 loop
    UTL_FILE.PUT_LINE(l_log_handle, cur2);
    end loop;
    utl_file.fclose_all;
    EXCEPTION
    WHEN UTL_FILE.INVALID_OPERATION THEN
    dbms_output.put_line('Invalid Operation For '|| l_global_file);
    UTL_FILE.FCLOSE_ALL;
    WHEN UTL_FILE.INVALID_PATH THEN
    dbms_output.put_line('Invalid Path For '|| l_global_file);
    UTL_FILE.FCLOSE_ALL;
    WHEN UTL_FILE.INVALID_MODE THEN
    dbms_output.put_line('Invalid Mode For '|| l_global_file);
    UTL_FILE.FCLOSE_ALL;
    WHEN UTL_FILE.INVALID_FILEHANDLE THEN
    dbms_output.put_line('Invalid File Handle '|| l_global_file);
    UTL_FILE.FCLOSE_ALL;
    WHEN UTL_FILE.WRITE_ERROR THEN
    dbms_output.put_line('Invalid Write Error '|| l_global_file);
    UTL_FILE.FCLOSE_ALL;
    WHEN UTL_FILE.READ_ERROR THEN
    dbms_output.put_line('Invalid Read Error '|| l_global_file);
    UTL_FILE.FCLOSE_ALL;
    WHEN UTL_FILE.INTERNAL_ERROR THEN
    dbms_output.put_line('Internal Error');
    UTL_FILE.FCLOSE_ALL;
    WHEN OTHERS THEN
    dbms_output.put_line('Other Error '||'SQL CODE: '||SQLCODE||' Messg: '||SQLERRM);
    UTL_FILE.FCLOSE_ALL;
    end;
    when running this script I am getting error
    ERROR at line 30:
    ORA-06550: line 30, column 2:
    PLS-00306: wrong number or types of arguments in call to 'PUT_LINE'
    ORA-06550: line 30, column 2:
    PL/SQL: Statement ignored
    if in the cursor declaration happen to use 'select menu_id from fnd_menus ' a plain record then it is successfully creating.
    If tried again revert to actual select statement ' select xmltype(cursor(select * from fnd_menus where rownum <101)) a from dual'
    then its erring out as above said.
    Please give me your valuable inputs in this regard.

    Hi,
    There are multiple ways to generate XML documents from relational data.
    Here are some :
    -- SQL/XML functions : XMLElement, XMLAgg, XMLAttributes etc.
    -- DBMS_XMLGEN package
    select dbms_xmlgen.getXML('SELECT * FROM scott.emp')
    from dual;-- XMLType constructor over a REF CURSOR (the one you chose)
    select xmlserialize(document
             xmltype(
               cursor(
                 select *
                 from scott.emp
             as clob
    from dual;-- From a DBUriType
    select xmlserialize(document
             dburitype('/SCOTT/EMP').getXML()
             as clob
    from dual;-- From XQuery using ora:view function
    select xmlserialize(document
             xmlquery('<ROWSET>{ora:view("SCOTT","EMP")}</ROWSET>' returning content)
             as clob indent size = 1
    from dual;If a column is NULL in the result set, those methods (except XMLElement) won't create the corresponding element.
    There's an option available for the XQuery method, but only in version 11.2.
    So if you want to output empty elements, you'll have to use DBMS_XMLGEN with setNullHandling method :
    DECLARE
    ctx   DBMS_XMLGEN.ctxHandle;
    v_out CLOB;
    rc    SYS_REFCURSOR;
    BEGIN
    OPEN rc FOR
      SELECT *
      FROM scott.emp
    ctx := DBMS_XMLGEN.newContext(rc);
    DBMS_XMLGEN.setNullHandling(ctx, DBMS_XMLGEN.EMPTY_TAG);
    v_out := DBMS_XMLGEN.getXML(ctx);
    DBMS_XMLGEN.closeContext(ctx);
    CLOSE rc;
    DBMS_XSLPROCESSOR.clob2file(v_out, 'TEST_DIR', 'test_out.xml');
    END;
    I thought of making use of the utl_file option in Oracle apps.You could, but you might find DBMS_XSLPROCESSOR.clob2file procedure more convenient for that (see above).
    All you have to do is serializing the XML in a CLOB variable, and call the procedure.
    WHERE NAME = 'utl_file_dir';The "utl_file_dir" init. parameter is deprecated since 10g, use directory objects instead.

  • Can we store ORACLE DATA and LOG files in seperate file system

    I am installing NW2004s in HP UNIX Server with Oracle database
    I have selected the option as custom
    I would want the SAP datafiles to be stored in /sapdata  file system
    Log files to be stored in /oraclelog file system
    While installation SAP is just asking me for the location of SAP data files. It is not asking me for the location of the log files.
    (It is asking me for the location of control files)
    Hence as per my understanding the oracle log files can be saved only in  the same directory as oracle Data file.
    Please confirm

    I have heard reports of people that made some kind of synchronization between AD and OID, but I have no hands on experience with this. There are some notes on metalink that describe the process, but I try to stay away from AD as far as possible (I usually work on unix or linux environments and those don't really mix with AD).

  • Oracle data int CSV file

    Hello,
    Is there a tool that I can use that capture output of Oracle SQL into CSV files?
    Thanks

    There are many tools that do this - SQLDeveloper is a "free" one (assuming you have a valid database license). TOAD, SQLNavigator, Discoverer etc are other tools you can use for a fee. As noted above, none of these tools can represent LOB data in csv format - they can be only used to export traditional data to csv.

  • How to extract Oracle data into Excel file?

    For a small automation project I have to extract data from a table/
    tables and append it to the existing excel file and feed that excel
    file to a command that will load data into some other environment. I
    am totally new to this. So to get started I wanted to know,
    1) How to extract data from sample table Foo which has columns A,B,C
    and append these values as new columns to an existing excel say
    fooresults.csv ?
    2) Can I achieve this in pl/sql script or do I need to write unix or
    perl script or some other programing language, please advise?

    The "extract data from a table" part is easy, you could do that with VB/ADO, or .NET/ODP.NET. It's then a matter of taking that data and appending it to a spreadsheet that might be the hard part, and how you'd do that exactly is really more of a Microsoft question than an Oracle one.
    If you want to be able to do this from the database itself and your database is on Windows, you could use either [.NET Stored Procedures|http://www.oracle.com/technology/tech/dotnet/ode/index.html] if you can manipulate the spreadsheet in .net code, or you could also use Oracle's [COM Automation Feature|http://www.oracle.com/technology/tech/windows/com_auto/index.html] if you're handy with the COM object model for Excel.
    How you'd do that exactly via either .net or com or vb is the crux of the problem and is something you'd need to know before it turns into an Oracle question, but if you already know how to do that and now just need to figure out a way to do that from Oracle, either of the above might help.
    Hope it helps,
    Greg

  • How to conver the oracle data into xml files

    Hi All,
    I have a table for ex emp, now i want to generate every row into an xml file. could anyone pls help...
    ex:- emp table
    eno ename sal
    1    bond  3000
    2    kiran    2000
    3    jai       1000
    4    henry   500
    o/p :-  i have to get a column in 4 different files for this 4 rows.
    1.xml file        should contain data  <ID>1</ID><eNAME>bond</eNAME><sal>3000</sal>
    2.xml file        should contain data  <ID>2</ID><eNAME>kiran</eNAME><sal>2000</sal>
    3.xml file       should contain data  <ID>3</ID><eNAME>jai</eNAME><sal>1000</sal>
    4.xml file       should contain data  <ID>1</ID><eNAME>bond</eNAME><sal>500</sal>
    regards,
    Badri.

    You can do it like this :
    begin
      for r in (
          select empno
               , xmlserialize(content xmlforest(empno as "ID", ename, sal)) as xmlcontent
          from scott.emp
      loop
        dbms_xslprocessor.clob2file(r.xmlcontent, 'TEST_DIR', to_char(r.empno) || '.xml');
      end loop;
    end;

  • BLOCK CORRUPTION (ORA-1578) 처리 (ORACLE 8I NEW FEATURE)

    제품 : ORACLE SERVER
    작성날짜 : 2002-05-31
    BLOCK CORRUPTION (ORA-1578) 처리 (ORACLE 8I NEW FEATURE)
    ========================================================
    PURPOSE
    Block Corruption의 처리 방안에 대해 알아본다.
    Problem Description
    block corruption 시 10210, 10211,10231 의 event 를 사용해서
    해당 block 을 skip 할 수도 있지만 V8.1 이상에서는
    dbms_repair.fix_corrupt_blocks ,
    dbms_repair.skip_corrupt_block 를 이용하여
    corrupt가 발생한 block을 detect하고 skip, 또는 repair해주는 방안이
    제시되고 있다.
    Workaround
    Solution Description
    - 먼저 detecting 을 위해 db_block_checking =true 를 init.ora 에 set
    - dbms_repair 의 package 를 사용하는데 이 package 는 dbmsrpr.sql,
    prvtrpr.plb를 수행한다 .
    - sys 로 접속하여 package 를 실행한다.
    다음의 예제를 살펴보자
    T1 테이블에 corrupt 된 block 이 있다고 가정한다.
    SQL> desc t1
    Name Null? Type
    COL1 NOT NULL NUMBER(38)
    COL2 CHAR(512)
    SQL> analyze table t1 validate structure;
    analyze table t1 validate structure
    ERROR at line 1:
    ORA-01498: block check failure - see trace file
    이때 ANALYZE로 부터 발생된 trace file 에 corrupt 된 block 에 3 row 의
    (nrows = 3) data 가 있음을 알수 있다고 가정하자.
    DBMS_REPAIR.ADMIN_TABLES (repair and orphan key)
    ================================================
    ADMIN_TABLES 은 table 을 위한 repair table과,인덱스를 위한 orphan key
    tables을 제공한다.

    Data Extraction
    ===============
    repair table에 의하면 file 6 ,block 3 에 corrupt 이 났음을 알수 있다
    그러나 아직 이 block 은 corrupt 로 mark 되어 있지 않으므로 필요 data 를
    추출하여야 한다.
    1. ALTER SYSTEM DUMP (nrows = 3) 에 의해 block안에 있는 row수를 결정한다.
    2. corrupt object를 select 하여 가능한 정보를 추출한다.
    SQL> -- The following query can be used to salvage data from a corrupt block.
    SQL> -- Creating a temporary table facilitates data insertion.
    SQL> create table temp_t1 as

  • DATA BLOCK CORRUPTION : ORA-1578 해결 방법

    제품 : ORACLE SERVER
    작성날짜 : 2005-08-18
    DATA BLOCK CORRUPTION : ORA-1578 해결 방법
    =========================================
    모든 오라클 데이타 블럭은 sequence 번호(seq)와 incarnation 번호(inc)를
    갖고 있다. ORA-1578 에러는 seq=0 이고 inc <> 0 (새로운 블럭이 아님)일 때
    발생한다. ORA-1578 에러는 ORA-600[3339] 에러와 함께 발생하곤 한다.
    ORA-1578 에러가 발생하면 corruption이 발생한 화일 번호와 블럭 번호를
    알려준다. 여기서는 이 때의 화일번호를 f, 블럭번호를 b 라고 부르기로 한다.
    <해결 방법>
    1) 우선 해야 할 일은 어떠한 오브젝트가 corrupt 되었는가를 알아내는 것이다.
    다음의 스크립트를 이용하면 알 수 있다.
    SQL>select segment_name, segment_type
    from dba_extents
    where file_id = f and
    b between block_id and block_id + blocks - 1;
    2) 만약 해당 세그먼트가 인덱스이면 drop 시키고 다시 생성하면 된다.
    3) 만약 해당 세그먼트가 테이블이면 corrupt된 블럭의 데이타는 손상된 것이다.
    4) 만약 해당 테이블이 들어있는 export 화일이 있다면 손상된 테이블을 drop
    시키고 import 받는 것이 제일 간단한 방법이다. 하지만, 만약 export 받은
    화일이 없거나 backup해 놓은 화일도 없다면 해당 테이블에 인덱스가 생성되어
    있는 경우에 한해서 다음의 방법을 사용해서 복구를 하도록 한다.
    5) 해당 테이블에 대한 인덱스가 생성되어 있다면 이를 이용해서 corrupt된
    블럭을 피해갈 수 있다. 이 방법은 다음과 같다.
    - empno, ename, deptno 를 컬럼으로 가지는 emp 테이블이 corrupt 되었다고
    가정하자. 그리고, empno 컬럼에 인덱스가 생성되어 있다고 하자. 클러스터화
    되지 않은 모든 테이블은 Unique한 rowid를 가진다.
    rowid를 varchar2/hexadecimal 형식으로 표현하려면 rowidtochar 함수를 이용
    한다.
    SQL> select rowidtochar(rowid) from emp;
    rowid는 총 18자로 block address(8자), dot(1자), row address(4자),
    dot(1자), file address(4자)로 구성되어 있다.
    SQL> select empno, rowid
    from emp
    where empno > 0
    위의 스크립트를 실행시키면 다음과 같은 결과를 얻게 된다.
    EMPNO ROWID
    100 00000003.0000.0006
    101 00000003.0001.0006
    102 00000003.0002.0006
    103 00000003.0003.0006
    500 00000004.0000.000A
    501 00000004.0001.000A
    755 0000001A.0005.000A
    756 0000001A.000C.000A
    만약 인덱스가 character 컬럼에 대한 것이었다면 위의 query 문장을 다음과 같
    이 바꿀 수 있다.
    SQL> select empno, rowid
    from emp
    where empno > '';
    예를 들어 다음과 같은 에러 메시지가 떨어졌다고 하자.
    01578, 00000, "ORACLE data block corrupted (file # 10, block # 4)
    그러면, 다음의 스크립트를 사용하여 손상된 블럭에 있는 employee 에 대한
    empno를 구할 수 있다.
    SQL> select empno from emp
    where empno > 0
    and rowidtochar(rowid) like '00000004.%.000A';
    EMPNO ROWID
    500 00000004.0000.000A
    501 00000004.0001.000A
    이제 emp 테이블과 같은 구조를 갖는 새로운 테이블을 만든다.
    SQL> create table temp
    as select * from emp
    where 1 = 2;
    그런 다음 손상된 부분을 피해서 새로운 테이블에 손상된 테이블의 데이타를
    추가한다.
    SQL> insert into temp select * from emp where empno < 500;
    SQL> insert into temp select * from emp where empno > 501;
    손상된 테이블을 drop 시키고 temp 테이블의 이름을 emp로 변경한다.
    그리고, 백업된 자료나 문서 자료를 통하여 손상된 부분에 대한 정보를 추가한다.
    6) 손상된 블럭에 여러 개의 row가 존재하고 있다면 다음의 방법을 이용한다.
    SQL> create table empnos as
    select empno from emp
    where empno > 0
    and rowidtochar(rowid) not like '00000004.%.000A';
    이 스크립트를 이용하면 손상된 block에 포함되지 않는 empno들을 알 수 있다.
    다음의 스크립트를 계속 실행시켜 복구를 한다.
    SQL> create table temp as select * from emp where 1 = 2;
    SQL> insert into temp
    select emp.empno, emp.ename, emp.deptno
    from emp, empnos
    where emp.empno > 0
    and emp.empno = empnos.empno;
    7) 만약 Data Dictionary의 table이나 index에서 손상된 block이 발생했다면
    지원을 요청해야 한다.
