--//实际上我一直认为能拷贝出来数据就ok了.这样恢复的数据库不能在使用,问题多多.
--//我继续测试实际上建表等操作都会报类似的:
ORA-00600: internal error code, arguments: [kdBlkCheckError], [1], [94232], [6110], [], [], [], [], [], [], [], []
--//这样的错误.主要问题在于system块的检查更加严格.

--//今天尝试恢复6110,6111,6112之类的错误.

1.环境:
SCOTT@book> @ ver1
PORT_STRING                    VERSION        BANNER
------------------------------ -------------- --------------------------------------------------------------------------------
x86_64/Linux 2.4.xx            11.2.0.4.0     Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

--//前面已经恢复只读状态exp操作是正常的.具体看前面的文章.
--//首先更正前面脚本的几个错误:http://blog.itpub.net/267265/viewspace-2565250/=> [20190130]删除tab$记录的恢复2.txt

 57                 echo "x /rx dba $dba *kdbr[$begin]" | rlbbed | egrep "^^flag@.*: *0x7c" > /dev/null
--//原来写成echo "x /rx dba $dba *kdbr[$begin]" | rlbbed | egrep "^^flag@.*: 0x7c" > /dev/null ,可能出现多个空格的情况.
 58                 if [ $? -eq 0 ]
 59                 then
 60                     echo "dba=$dba;ckix_value=0" >> scan4a.txt
 61                 fi

$ cat scana.sh
#! /bin/bash
cat clearout.txt | while read dba
do
    echo set dba $dba
    echo -n "assign "
    echo -e  "set dba $dba \np ktbbh" |rlbbed | /bin/grep -B 4 -A 9 "ub4 kxidsqn \+@.*0x00000751$"| egrep "ktbbhitl|ktbitflg" | cut -c11-21,55-60 | paste -d. - - | sed -e 's/   /=/'
--//这里写错,原来写成4204236,实际上应该是$dba,
    echo sum apply dba $dba
done

--//注:http://blog.itpub.net/267265/viewspace-2565250/=> [20190130]删除tab$记录的恢复2.txt 里面的脚本已经更正.

2.我前面做了冷备份.首先恢复冷备份:
$ /bin/cp -r /home/oracle/backup/book_20190122_bad/* /mnt/ramdisk/book/
*/

$ . scan.sh
process 1 start : 2019/02/12 08:45:44 scan dba 1,144 ,  create scan1.txt about ktetbdba,ktetbnbk
process 1 finish: 2019/02/12 08:45:44,enter continue...
process 2 start : 2019/02/12 08:45:45 scan block , get kdbtnrow,kdbtoffs ang grep kdbtnrow=0
process 2 finish: 2019/02/12 08:46:16,enter continue...
process 3 start : 2019/02/12 08:46:50 scan block , create bbed'script scan3_bbed.txt for modify delete of flag  and create scan4a.txt about block of ckix
process 3 finish: 2019/02/12 08:52:01,enter continue...
process 4 start : 2019/02/12 08:52:06 create bbed's scan4_b
