Oracle：执行Job dbms_scheduler-Java 学习之路

我想在Oracle Database 11g Express Edition 11.2.0.2.0版中执行调度程序 - 64位生产环境我有这个包：

create or replace PACKAGE  "S_IN_TDK" is


procedure parseMsg;

end;

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;

但是当我运行这份工作时，我收到了这个错误：

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

我也试过了

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;

但后来我收到了这个错误：

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.

DBMS_SCHEDULER.CREATE_JOB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, 以立即运行作业 .

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;

参数 program_name 需要调度程序 PROGRAM 对象的名称 . 如果要运行内联程序，请改为使用 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 .
