用隐含参数强制OPEN数据库后会有很多遗留问题，如：需重建UNDO表空间，此外还会伴随有ORA-08102错误

刚才做破坏online日志实验的时候采用加隐含参数强制打开过数据库，之后alert日志就一直会报ORA-08102

根据metalink上的文章：

ORA-08102: TRYING TO MANIPULATE A JOB IN DBA_JOBS [ID 1036858.6]

Solution Description:
=====================

You need to recreate the inex I_JOB_NEXT.

Script "$ORACLE_HOME/rdbms/admin/cat7103.sql" creates the I_JOB_NEXT:

Drop and recreate this index.

connect sys/
drop index i_job_next;
create index i_job_next on job$ (next_date)

Note: alter index I_JOB_NEXT rebuild;

Will not fix the problem.

重建索引是没有用的，必须先删除，，再重新创建

1.先删除索引i_job_next

SYS@ora10g> drop index i_job_next;

Index dropped.

2重建索引i_job_next;

SYS@ora10g> create index i_job_next on job$ (next_date);

Index created.

重建索引后，问题解决。所以，在没有必要的情况下，不要轻易去用隐含参数_allow_resetlogs_corruption=true去强制打开数据库，有隐患，如果不知道处理方法，仍然会对数据库产生影响。
