[英]how to schedule a pgagent job through scripts/commandLine
I want to run jobs through PgAgent. 我想通过PgAgent运行作业。
I am able to do that by creating a job in PgAgentJob through PgAdmin UI, as described here https://www.pgadmin.org/docs/pgadmin4/dev/pgagent_jobs.html . 我可以通过PgAdmin UI在PgAgentJob中创建作业来做到这一点,如此处https://www.pgadmin.org/docs/pgadmin4/dev/pgagent_jobs.html所述 。
But I want to use a sql script that can create a PgAgent job as we do in Oracle. 但是我想使用一个可以像在Oracle中一样创建PgAgent作业的sql脚本。 Please suggest how I can achieve this.
请提出如何实现这一目标。
To create a job in pgAgent use something like the following INSERT STATEMENTS
(for a Routine Maintenance
job) : 要在pgAgent中创建作业,请使用以下
INSERT STATEMENTS
(用于Routine Maintenance
作业):
INSERT INTO pgagent.pga_job (jobid, jobjclid, jobname, jobdesc, jobenabled, jobhostagent)
SELECT jcl.jclid, 'MyJob', '', true, ''
FROM pgagent.pga_jobclass jcl WHERE jclname='Routine Maintenance';
To add a step to this job, which executes a SQL command ( 'delete from test where user_name=''test'';
), use the following command: 要向该作业添加执行SQL命令的步骤(
'delete from test where user_name=''test'';
),请使用以下命令:
INSERT INTO pgagent.pga_jobstep (jstjobid, jstname, jstdesc, jstenabled, jstkind, jstonerror, jstcode, jstdbname, jstconnstr)
SELECT (SELECT jobid
FROM pgagent.pga_job
WHERE jobname = 'MyJob'), 'MyStep', '', true, 's', 'f', 'delete from test where user_name=''test'';', 'postgres', '';
To create a schedule for this job (every day at 08:45), use the following command: 要为此作业创建时间表(每天08:45),请使用以下命令:
INSERT INTO pgagent.pga_schedule (jscjobid, jscname, jscdesc, jscminutes, jschours, jscweekdays, jscmonthdays, jscmonths, jscenabled, jscstart, jscend)
VALUES((SELECT jobid
FROM pgagent.pga_job
WHERE jobname = 'MyJob'), 'MySchedule', '', '{f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f,t,f,f,f,f,f,f,f,f,f,f,f,f,f,f}',
'{f,f,f,f,f,f,f,f,t,f,f,f,f,f,f,f,f,f,f,f,f,f,f,f}', '{t,t,t,t,t,t,t}', '{t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t,t}',
'{t,t,t,t,t,t,t,t,t,t,t,t}', true, '2018-07-16 00:00:00', NULL);
Here a graphical representation of this schedule: 这里是该时间表的图形表示:
Here you can see a complete summary of these commands inside an anonymous block (generated by pgAdmin): 在这里,您可以在匿名块(由pgAdmin生成)中看到这些命令的完整摘要:
