Rman备份是11.2.0.1，所以在恢复的过程中，全备会将一些基础信息表以及系统信息表都恢复成11.2.0.1的信息，所以在恢复recover完打开数据库，就和现有版本11.2.0.4冲突了，而没法open database。

DOC> The following PL/SQL block invokes UTL_RECOMP to recompile invalid

DOC>
DOC> Use the following queries to track recompilation progress:
DOC>
DOC> 1. Query returning the number of invalid objects remaining. This

DOC> This script automatically chooses serial or parallel recompilation

DOC> by the number of threads per CPU (parameter parallel_threads_per_cpu).
DOC> On RAC,this number is added across all RAC nodes.
DOC>
DOC> UTL_RECOMP uses DBMS_SCHEDULER to create jobs for parallel
DOC> recompilation. Jobs are created without instance affinity so that they

DOC>
DOC> 1. Query showing jobs created by UTL_RECOMP
DOC> SELECT job_name FROM dba_scheduler_jobs
DOC> WHERE job_name like 'UTL_RECOMP_SLAVE_%';
