ORA-12012: error on auto execute of job "ORACLE_OCM

ALERT日志中报错例如以下：

数据库版本号：

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
PL/SQL Release 11.2.0.3.0 - Production
CORE    11.2.0.3.0      Production
TNS for IBM/AIX RISC System/6000: Version 11.2.0.3.0 - Production

參考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.   ---文件夹不存在

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。

该错误仅仅出如今OracleRDBMS 11.2.0.3 的版本号（新安装的db，或者从其它版本号升级到11.2.0.3的）。或者Oracle Configuration Manager 的版本号大于10.3.3.0.0。

To verify the OCM db directories, run as sysdba:  ---能够通过以下语句确认下文件夹是否不存在
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.

假设不须要向MOS上传搜集信息，能够删除用户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 10.3.1,參考MOS文档：How To Manually Remove ORACLE_OCM From Database (文档 ID 859113.1)

解决方法：
如不须要使用此功能，能够删除用户ORACLE_OCMT和对应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;
