下面是测试一把access$基表丢失的恢复方法
欢迎大家加入ORACLE超级群：17115662 免费解决各种ORACLE问题,以后BLOG将迁移到http://www.htz.pw
1，数据库版本
| www.htz.pw > select * from v$version;
BANNER -------------------------------------------------------------------------------- Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production PL/SQL Release 11.2.0.3.0 - Production CORE 11.2.0.3.0 Production TNS for Linux: Version 11.2.0.3.0 - Production NLSRTL Version 11.2.0.3.0 - Production |
2，启动报错
| www.htz.pw > startup force ORACLE instance started.

ORA-01092: ORACLE instance terminated.

alert下面报这个错误 这里报递归的SQL出现错误，原因表不存在。下面alert中的日志内容

下面通过10046的方法来实现具体在那条语句报错 [oracle@www.htz.pw sql]$sqlplus / as sysdba

这里可以看到是表access$表不存在 PARSE ERROR #182956478584:len=56 dep=1 uid=0 oct=3 lid=0 tim=1402404227784268 err=942 select order#,columns,types from access$ where d_obj#=:1 ORA-00704: bootstrap process failure ORA-00604: error occurred at recursive SQL level 1 ORA-00942: table or view does not exist ORA-00704: bootstrap process failure ORA-00604: error occurred at recursive SQL level 1 ORA-00942: table or view does not exist

3，重建access$基表
建议的办法很简单，重启到数据库到upgrade模式，重建基表就可以了。
| create table access$ /* access table */ ( d_obj# number not null, /* dependent object number */ order# number not null, /* dependency order number */ columns raw("M_BVCO"), /* list of cols for this entry */ types number not null) /* access types */ storage (initial 10k next 100k maxextents unlimited pctincrease 0) /
create index i_access1 on access$(d_obj#, order#) storage (initial 10k next 100k maxextents unlimited pctincrease 0)
/
www.htz.pw > create table access$ /* access table */ 2 ( d_obj# number not null, /* dependent object number */ 3 order# number not null, /* dependency order number */ 4 columns raw("M_BVCO"), /* list of cols for this entry */ 5 types number not null) /* access types */ 6 storage (initial 10k next 100k maxextents unlimited pctincrease 0) 7 / columns raw("M_BVCO"), /* list of cols for this entry */ * ERROR at line 4: ORA-00910: specified length too long for its datatype
在其它相同的版本看到这个是126，但是不知道为什么从脚本弄出来的是一个字符串
SQL> desc access$; Name Null? Type ----------------------------------------- -------- ---------------------------- D_OBJ# NOT NULL NUMBER ORDER# NOT NULL NUMBER COLUMNS RAW(126) TYPES NOT NULL NUMBER
create table access$ /* access table */ ( d_obj# number not null, /* dependent object number */ order# number not null, /* dependency order number */ columns raw(126), /* list of cols for this entry */ types number not null) /* access types */ storage (initial 10k next 100k maxextents unlimited pctincrease 0) /
