  • [Oracle][Corruption]发生ORA00600[kdsgrp1]的时候,如何进行调查


    本质上,这很可能是坏块引发的,所以需要调查 关联的Table 中的坏块状况:

    Excerpt of trace file
    ============================
    *** 2017-08-18 09: 23: 04.323
    dbkedDefDump (): Starting incident default dumps (flags = 0x2, level = 3, mask = 0x0)
    [TOC00009]
    ----- Current SQL Statement for this session (sql_id = 7snqrq5th8ddh) -----
    with tmp001 as (
    ...
    (Short)
    ...

    select
    count (*)
    from
    tmp001 2
    where 1 = 1

    and ROWNUM <=: 9
    ============================


    Please check each table above for damage respectively:

    1. Check whether there is a problem with the structure of each table:

    Example:

    analyze table table name validate structure;
    analyze table table name validate structure cascade;

    2. Check the data files to which the above tables belong:

    Example:

    --- How to check the name of the data file belonging to the table:

    SQL> select file_name from dba_tables t1, dba_data_files t2
    Where t1.tablespace_name = t2.tablespace_name
    And t1.owner = 'Owner name' and t1.table_name = 'Table name';

    --- How to check for corruption in data files:

    $ rman target /
    RMAN> backup check logical validate datafile 'the acquired data file name';

    After checking, please check whether there is damage in V $ DATABASE_BLOCK_CORRUPTION view:

    SQL> select * from V $ DATABASE_BLOCK_CORRUPTION;


    If the error occurs and the breakage can be confirmed by the above check, it separates whether it is temporary damage on memory
    Please restart the database, please check again.
