我是我的包裹,我正在排队多个这样的工作:
dbms_scheduler.create_job
( job_name => p_job_name
, job_type => 'PLSQL_BLOCK'
, job_action => p_sql_code
, start_date => SYSDATE
, enabled => TRUE
, comments => 'Running batch jobs in parallel');
一旦我为希望开始的许多并行作业完成了此操作,我需要阻止,直到所有作业都完成。
目前我不得不睡觉并轮询表格ALL_SCHEDULER_JOB_RUN_DETAILS
并ALL_SCHEDULER_JOBS
检查工作的状态。这似乎是一个非常丑陋的解决方案。这是我使用的 SQL:
PROCEDURE run_jobs
( p_jobs StringTableType
, p_sql VARCHAR2(4000) )
IS
l_jobs StringTableType;
l_status sys_type.STRING;
l_additional_info sys_type.text;
l_done BOOLEAN;
i PLS_INTEGER;
BEGIN
l_jobs := p_jobs;
-- Submit jobs
FOR i IN 1..l_jobs.COUNT LOOP
dbms_scheduler.create_job
( job_name => l_jobs(i)
, job_type => 'PLSQL_BLOCK'
, job_action => p_sql
, start_date => SYSDATE
, enabled => TRUE
, comments => 'Running batch jobs in parallel');
END LOOP;
-- now wait untile all jobs are finished
l_done := FALSE;
WHILE NOT l_done LOOP
DBMS_LOCK.sleep(5);
l_done := TRUE;
i := l_jobs.FIRST;
WHILE i IS NOT NULL LOOP
WITH jobs_log
AS (SELECT job_name, state status, '' additional_info
FROM all_scheduler_jobs
UNION
SELECT job_name, status, additional_info
FROM all_scheduler_job_run_details
)
SELECT status, additional_info
INTO l_status, l_additional_info
FROM jobs_log
WHERE job_name = p_jobs (i);
--Analyze job status
CASE
WHEN l_status = 'RUNNING' THEN
l_done := FALSE;
WHEN l_status = 'SUCCEEDED' THEN
l_jobs.DELETE(i);
WHEN l_status = 'FAILED' THEN
l_jobs.DELETE(i);
ELSE
l_done := FALSE;
END CASE;
i := l_jobs.NEXT(i);
END LOOP;
END LOOP;
END run_jobs;
在所有作业完成之前,如何阻止我的代码?如果有更好的方法,谁能给我一个例子?
