有一朋友数据库启动出现报ORA-01092 ORA-00704 ORA-00942错误

印象比较深的在某些版本中数据库由于access$丢失会出现类似错误:Oracle 11g丢失access$恢复方法，对数据库进行跟踪分析发现

PARSE ERROR #140521486058480:len=208 dep=1 uid=0 oct=9 lid=0 tim=1393010401966006 err=942

创建基表的I_OBJ1失败,这种情况比较少见,难道是obj$表丢失了，或者损坏了？搜索trace文件,发现没有obj$表创建成功

[root@xifenfei trace]# grep -i "CREATE TABLE" xifenfei_ora_31822.trc
create table bootstrap$ (
CREATE TABLE TAB$("OBJ#"
CREATE TABLE CLU$("OBJ#"
CREATE TABLE FET$("TS#" N
CREATE TABLE UET$("SEGFIL
CREATE TABLE SEG$("FILE#"
CREATE TABLE UNDO$("US#"
CREATE TABLE TS$("TS#" NU
CREATE TABLE FILE$("FILE#

CREATE TABLE COL$("OBJ#"
CREATE TABLE USER$("USER#
CREATE TABLE PROXY_DATA$(
CREATE TABLE PROXY_ROLE_D
CREATE TABLE CON$("OWNER#
CREATE TABLE CDEF$("CON#"
CREATE TABLE CCOL$("CON#"

应该是obj$表没有被创建成功,通过dbv进一步分析

由于block损坏导致obj$表创建异常,从而使得出现此类问题，通过bbed修复坏块之后

BBED> verify

然后启动数据库,正常启动成功
