去除UTL_FILE导致的ORA-12012 ORA-04068 ORA-04063 ORA-06508

前些天由于安全等原因，应客户要求，去除了PUBLIC用户的UTL_FILE的权限

结果导致了全部数据库报类似如下错误：

ORA-12012: error on auto execute of job 52
ORA-04068: existing state of packages has been discarded
ORA-04063: package body "ORACLE_OCM.<package name>" has errors
ORA-06508: PL/SQL: could not find program unit being called
（ORACLE官方示例）

解决方法：
SQL> grant execute on UTL_FILE to oracle_ocm;
SQL> grant execute on DBMS_SCHEDULER to oracle_ocm;
SQL> ALTER PACKAGE oracle_ocm.MGMT_DB_LL_METRICS compile;
SQL> ALTER PACKAGE oracle_ocm.mgmt_config compile;
