【问题描述】：

我想在 Oracle Database 11g Express Edition Release 11.2.0.2.0 - 64bit Production 中执行调度程序我有这个包裹：

create or replace PACKAGE  "S_IN_TDK" is


procedure parseMsg;

end;

还有这份工作

BEGIN
  DBMS_SCHEDULER.CREATE_JOB (
   job_name         =>  'parseMsg',
   program_name     =>  'S_IN_TDK.parseMsg',
   repeat_interval  =>  'FREQ=SECONDLY;INTERVAL=10',
   --job_style        => 'LIGHTWEIGHT',
   comments         => 'Job that polls device n2 every 10 seconds');
END;

但是当我运行作业时，我得到了这个错误：

Fallo al procesar el comando SQL
- ORA-27476: "S_IN_TDK.PARSEMSG" does not exist
ORA-06512: at "SYS.DBMS_ISCHED", line 185
ORA-06512: at "SYS.DBMS_SCHEDULER", line 486
ORA-06512: at line 2

我也试过

BEGIN
  DBMS_SCHEDULER.CREATE_JOB (
   job_name         =>  'parseMsg',
   job_action       =>  'begin S_IN_TDK.parseMsg; end;',
   repeat_interval  =>  'FREQ=SECONDLY;INTERVAL=10',
   --job_style        => 'LIGHTWEIGHT',
   comments         => 'Job that polls device n2 every 10 seconds');
END;

但后来我得到了这个错误：

 Informe de error -
ORA-06550: line 2, column 3:
PLS-00306: wrong number or types of arguments in call to 'CREATE_JOB'
ORA-06550: line 2, column 3:

*Cause:    Usually a PL/SQL compilation error.

【解决方案1】：

参数program_name 需要调度程序的名称PROGRAM 对象。如果您想运行内联程序，请改用job_action 参数：

BEGIN
  DBMS_SCHEDULER.CREATE_JOB (
   job_name         =>  'parseMsg',
   job_action       =>  'begin S_IN_TDK.parseMsg; end;',
   repeat_interval  =>  'FREQ=SECONDLY;INTERVAL=10',
   --job_style        => 'LIGHTWEIGHT',
   comments         => 'Job that polls device n2 every 10 seconds');
END;

请注意，job_action 需要一个完整的 PL/SQL 块作为输入。

【解决方案2】：

DBMS_SCHEDULER.CREATE_JOB 具有三个必需参数：job_name、job_type 和 job_action。添加job_type => 'PLSQL_BLOCK', 并添加enabled => true, 以使作业立即运行。

BEGIN
  DBMS_SCHEDULER.CREATE_JOB (
   job_name         =>  'parseMsg',
   job_type         =>  'PLSQL_BLOCK',
   job_action       =>  'begin S_IN_TDK.parseMsg; end;',
   repeat_interval  =>  'FREQ=SECONDLY;INTERVAL=10',
   --job_style        => 'LIGHTWEIGHT',
   enabled          =>  true,
   comments         => 'Job that polls device n2 every 10 seconds');
END;
/

使用此查询检查作业状态：

select *
from dba_scheduler_job_run_details
where job_name = 'PARSEMSG'
order by log_date desc;
