DBSNMP用户的BSLN_INTERNAL出现ORA-12012和ORA-6502错误的解决方法

检查日志发现出现下述错误：

[sql]
view plaincopy

ORA-12012: error on auto execute of job "SYS"."BSLN_MAINTAIN_STATS_JOB"
ORA-06502: PL/SQL: numeric or value error
ORA-06512: at "DBSNMP.BSLN_INTERNAL", line 2073
ORA-06512: at line 1

一个临时的解决方案是禁用这个job。

[sql]
view plaincopy

BEGIN
sys.dbms_scheduler.disable( '"SYS"."BSLN_MAINTAIN_STATS_JOB"' );
END;

查询MOS后发现原来是权限的问题：

【参考文档】AlertLog Errors: ORA-12012: Error On Auto Execute Of Job, ORA-06512: at "DBSNMP.BSLN_INTERNAL" [ID 1329618.1]

需要授予DBSNMP用户对SYS.DBMS_JOB 有EXECUTE的权限。

[sql]
view plaincopy

SQL> select * from dba_tab_privs where table_name = 'DBMS_JOB';

GRANTEE OWNER TABLE_NAME GRANTOR PRIVILEGE GRANTABLE HIERARCHY
--------------- -------- ------------- --------- ------------- --------- ---------
SYSMAN SYS DBMS_JOB SYS EXECUTE NO NO
OWBSYS SYS DBMS_JOB SYS EXECUTE NO NO
APEX_030200 SYS DBMS_JOB SYS EXECUTE NO NO
EXFSYS SYS DBMS_JOB SYS EXECUTE NO NO
PUBLIC SYS DBMS_JOB SYS EXECUTE NO NO

[sql]
view plaincopy

SQL> grant EXECUTE on SYS.DBMS_JOB to DBSNMP;

Grant succeeded
