如果configdb不成功，有可能还会出现weblogic的异常。一般情况下我们会执行RestoreFromBackup来解决，不过当configdb与RestoreFromBackup都不能成功执行时就得想想办法了

二、解决办法
按以下办法依次执行，到解决成功为至。
第一种办法：
执行RestoreFromBackup.bat
第二种办法
1、找出建立不成功的索引：
select * from MAXSYSINDEXES where name not in ( select a.index_name from dba_indexes a) and changed='N'
说明如下：
CHANGED有三种取值：
Y：表示索引是刚添加的，还没有进行configdb。
N：表示索引已添加好了，已进行过configdb作业
D：表示索引已删除，还没有进行configdb
2、删除建立不成功的索引
delete from maxsyskeys where ixname in ( select name from maxsysindexes where name not in ( select a.index_name from dba_indexes a) and changed='N');
delete frommaxsysindexes where name not in ( select a.index_name from dba_indexes a) and changed='N';
3、找到即将要通过configdb建立索引，但是数据库已经存在的索引。
select * from maxsysindexes where name in( select a.index_name from dba_indexes a) and changed in ('Y')
4、删除即将要通过configdb建立索引，但是数据库已经存在的索引
delete from maxsyskeys where ixname in 
( select name from maxsysindexes where namein ( select a.index_name from dba_indexes a) and changed='Y');
delete frommaxsysindexes where namein ( select a.index_name from dba_indexes a) and changed='Y';

5、删除不一致的索引
delete frommaxsyskeys where ixname not in (select name from maxsysindexes)
6、清除垃圾索引
A、查找出垃圾索引
select index_name from dba_ind_columns c where c.index_name not in (select index_name from dba_indexes)
B、清除之，
命令为：purge index \"垃圾索引名\"
这个时候的索引名是一大堆无意义的符号,按查出的结果集一条一条清理。
第三种办法
如果前面二种办法还不能解决，那只能出狠招了：
A、delete from maxsyskeys where ixname in 
( select name from maxsysindexes where changed='Y');
delete frommaxsysindexes wherechanged='Y';
B、进行configdb
C、启动weblogic,进入系统进行数据配置重设索引。
