最近同事报料，数据库无法执行一些关于数据字典的查询。即使是查询dba_users都会出现错误。从错误日志来看，全部是数据字典的一些错误信息，而用户数据还是ok的。Google了一下，看了看metalink，需要重建数据字典。那就执行catalog.sql吧。晕，竟然连执行这个SQL语句都报错！数据没有备份呢，汗!!! 如果你也是无法成功执行catalog.sql，接着往下看。

二、故障分析
oracle@DBBK10P:~> oerr ora 4045
04045, 00000, "errors during recompilation/revalidation of %s.%s"
// *Cause: This message indicates the object to which the following
// errors apply. The errors occurred during implicit
// recompilation/revalidation of the object.
// *Action: Check the following errors for more information, and
// make the necessary corrections to the object.
--从前面的错误描述来看及所发生的对象来看，系统用户LBACSYS这个对象错误了，为无效对象
--尝试重新编译，问题依旧
--下面直接执行catalog，执行时其日志文件出现大量的错误提示。也就是说无法重建数据字典
--尝试了使用restirct 方式来重启DB后执行，依旧出现相同的错误

--折腾了一下下午，后来参照Doc ID 457415.1给出的解决方案搞定
三、故障解决
--下面直接列出Doc ID 457415.1文章给出的解决方案与步骤，具体不再演示
metalink上的文章：ORA-4045 Error During Recompilation/Revalidation Of SYS.DBMS_STANDARD (Doc ID 457415.1)
Symptoms
Catproc.sql fails with the following error:
ERROR at line 1:
ORA-04045: errors during recompilation/revalidation of SYS.DBMS_STANDARD
ORA-04021: timeout occurred while waiting to lock object SYS.CDC_ALTER_CTABLE_BEFORE
Cause
Trying to create a database from a database that already exists.
1. Modify init.ora to contain:
_system_trig_enabled=FALSE
job_queue_processes=0
aq_tm_processes=0
Save init.ora
The following instructions are to be completed from sqlplus as the SYS user:
2. Issue a shutdown immediate:
SQL> shutdown immediate
3. SQL> startup pfile='<insert full path of init.ora here>'
4. SQL> @catalog.sql
5. SQL> @catproc.sql
6. Check for invalids from dba_objects:
SQL> select owner, object_name from dba_objects where status='INVALID';
7. Run utlrp.sql:
SQL> @utlrp.sql
8. Check for invalids again.
SQL> select owner, object_name from dba_objects where status='INVALID';
