BBED模拟并修复

SQL> alter database open;

ERROR at line 1:
ORA-01092: ORACLE instance terminated. Disconnection forced

利用:第三方工具GDUL,导出mount下库的数据,导入到新的库。以解决这个灾难

部分处理过程:

oradebug:生成10046事件,观察报错信息:
alter session set tracefile_identifier='elon';
alter session set events '10046 trace name context forever,level 12';
alter session set events '10046 trace name context off';

 

查文件块号:
select
dbms_rowid.ROWID_RELATIVE_FNO(rowid) fno,
dbms_rowid.ROWID_BLOCK_NUMBER(rowid) bno,
dbms_rowid.ROWID_ROW_NUMBER(rowid) rowno from sys.tab$ ;

select max(dbms_rowid.ROWID_BLOCK_NUMBER(rowid)) bno from sys.tab$ ;
select min(dbms_rowid.ROWID_BLOCK_NUMBER(rowid)) bno from sys.tab$ ;

select distinct file_no, blk_no
from
(
select dbms_rowid.rowid_relative_fno(rowid) file_no, dbms_rowid.rowid_block_number(rowid) blk_no from sys.tab$
) order by file_no, blk_no;


生成copy 语句:
select 'copy file 100 block ' || blk_no || ' to file 1 block ' || blk_no || ';'
from
(
select distinct dbms_rowid.rowid_relative_fno(rowid) file_no, dbms_rowid.rowid_block_number(rowid) blk_no
from sys.tab$
order by file_no, blk_no
);

select distinct file_no, blk_no
from
(
select dbms_rowid.rowid_relative_fno(rowid) file_no, dbms_rowid.rowid_block_number(rowid) blk_no from sys.tab$
)
where blk_no = 31497;

file: 1, 块号是169,170,145


vi filelist.txt

4 /home/oracle/oradata/dstdw/users01.dbf
5 /home/oracle/oradata/dstdw/credit.dbf
100 /tmp/system01.dbf.new

vi par.bbd
blocksize=8192
listfile=filelist.txt
mode=edit

从备份文件中copy良好的数据块进行恢复
[oracle@ ~]$ bbed parfile=par.bbd
password:blockedit

BBED>copy file 100 block 169 to file 1 block 169;
BBED>copy file 100 block 170 to file 1 block 170;
BBED>copy file 100 block 145 to file 1 block 145;

BBED> verify
