参考MOS文档：
"ORA-12012: error on auto execute of job ORACLE_OCM.MGMT_CONFIG_JOB_2_1" And "ORA-29280: invalid directory path" In Database AlertLog (文档 ID 1453959.1)
报错原因是：
Newer database releases are automatically instrumented for OCM collections. But here, the OCM instrumentation job is trying to write to a "state" directory which doesn't yet exists. ---目录不存在
ORACLE_OCM 账户是用来管理Oracle Configuration Manager的。 默认情况下， 该账户是Expired and locked状态。
该错误只出现在OracleRDBMS 11.2.0.3 的版本（新安装的db，或者从其他版本升级到11.2.0.3的），或者Oracle Configuration Manager 的版本大于10.3.3.0.0。
To verify the OCM db directories, run as sysdba: ---可以通过下面语句确认下目录是否不存在
SQL>select * from dba_directories where DIRECTORY_NAME like '%OCM_CONFIG%';
MGMT_DB_LL_METRICS wants to write to ORACLE_OCM_CONFIG_DIR2, which is not created by the built-in instrumentation scripts.
如果不需要向MOS上传搜集信息，可以删除用户ORACLE_OCM来解决，语句：
when not using the OCM Collector, remove the OCM objects from database:
SQL> drop user ORACLE_OCM cascade;
OCM is a standalone, separate tool and removing won't affect the database functionality.

如是10g--Version 10.2.3 to 10.3.1,参考MOS文档：How To Manually Remove ORACLE_OCM From Database (文档 ID 859113.1)
解决方法：
如不需要使用此功能，可以删除用户ORACLE_OCMT和相应DIRECTORY来解决，语句：
In order to manually remove the ORACLE_OCM user and associated objects from database, run:
SQL> drop user ORACLE_OCM cascade;
SQL> drop directory ORACLE_OCM_CONFIG_DIR;
