把基于事件的schedule改写：

out型参数介绍
create or replace procedure proc_test( p_1 number , p_2 out number)
is
begin
update employees set salary=10000 where employee_id=p_1;
select salary into p_2 from employees where employee_id=p_1;
end;
select * from user_errors;
测试
declare
v_salary number(8,2);
begin
proc_test(100,v_salary);
dbms_output.put_line(v_salary);
end;
in-out型参数介绍
create or replace procedure proc_test_io( p_1 in out number )
is
begin
p_1 := p_1*2;
end;
select * from user_errors;
测试
declare

dbms_output.put_line(v_1);
end;
alter table scheduler_test add ( event_name varchar2(40)) ;
create or replace procedure procnew( p_1 t_event_queue_payload )

end;
注：如果创建的程序需要输入参数，则必须定义完参数后在激活，即创建这个program时将enable设为false，否则提示：
Ora-27456：程序“ ”的参数并未全部定义；然后再对该program定义参数即执行define_program_argument过程（见1.3）。

1.3 define_program_argument
参数说明：
program_name——程序名称
argument_position——参数位置（也可以知道参数名称选择argument_name）
argument_type——参数类型
default_value——参数默认值
例子：
BEGIN
dbms_scheduler.define_program_argument(program_name => 'myprogram',
argument_position => 1,
argument_name => 'p_lttid',
argument_type => 'varchar2',
default_value => 'daaa');
END;
--查看定义的program参数
SELECT *FROM User_Scheduler_Program_Args;
1.4 define_anydata_argument（用于定义输入参数为复杂类型需采用sys.AnyData类型来包装的参数）
参数说明：
program_name——程序名称
argument_position——参数位置（也可以知道参数名称选择argument_name）
argument_type——参数类型为sys.AnyData
default_value——参数默认值
1.5 define_metadata_argument
有效的metadata attributes有: 'job_name', 'job_subname', 'job_owner', 'job_start', 'window_start',
'window_end', and 'event_message'.
Metadata Attribute Data Type Description
job_name VARCHAR2 当前执行的job名称
job_subname VARCHAR2 当前执行的job子名称
job_owner VARCHAR2 当前执行的job所有者
job_start TIMESTAMP WITH TIME ZONE job启动的时间
window_start TIMESTAMP WITH TIME ZONE window打开的时间
window_end TIMESTAMP WITH TIME ZONE window关闭的时间
event_message 事件触发job启动的信息
例子：（以下metadata_attribute设置为job_name，即以job_start这个值作为输入参数）
BEGIN
dbms_scheduler.define_metadata_argument(program_name => 'myprogram',
argument_position => 1,
argument_name => 'p_lttid',
metadata_attribute => 'job_start');
END;
1.6 drop_program_argument
例子：
BEGIN
dbms_scheduler.drop_program_argument(program_name => 'myprogram',
argument_position => 1);
END;
*/
begin
dbms_scheduler.define_metadata_argument (
program_name => 'programnew',
argument_position => 1 ,
metadata_attribute => 'EVENT_MESSAGE') ;
end;
select * from user_scheduler_program_args;
begin
dbms_scheduler.enable ('programnew');
end;

/*
Next we define the database destination. The agent parameter should reference the destination name associated with the remote agent. If the tns_name parameter is NULL, the default instance on the remote host is assumed. This default instance is defined by the ORACLE_SID and ORACLE_HOME parameters in the "schagent.conf" file on the remote server. If a tns_name is specified, it can either be a complete Oracle Net connect descriptor, or a regular alias, but it must be resolvable on the database running the scheduler, not just the remote host.
*/
create_database_destination
创建目标数据库，用于执行远程job
AGENT——The external destination name of the Scheduler agent to connect. Equivalent to an agent name.
The external destination must already exist. The external destination representing an agent is
created automatically on a database instance when the agent registers with that instance.
An agent‘s name is specified in its agent configuration file. If it is not specified, it defaults
to the first part (before the first period) of the name of the host it resides on.

/*
The group_type parameter determines the type of group created (DB_DEST, EXTERNAL_DEST). The member parameter contains a comma separated list of destinations, which must already exist. The syntax for a destinations is as follows.
[[schema.]credential@][schema.]destination
The keyword "LOCAL" can be used to indicate the job should be run on the local machine also. In the case of remote external jobs the LOCAL keyword can be prefixed with a credential, but for database jobs it can not and always runs using the credentials of the owner of the job.
*/
create_group
参数：
group_type——组类型，该组的所有成员必须是同一类型，已有的类型有三种：
DB_DEST：即成员为目标数据库，执行远程数据库的job；
EXTERNAL_DEST（External destination）：Members are external destinations, for running remote external jobs；
WINDOW：Members are Scheduler windows
The inclusion of the credential_name parameter is unnecessary here, but it specifies a default credential to use if any of the destinations in the group were defined without an explicit credential.
创建时可以指定成员也可不指定，添加成员通过add_group_member过程添加。
BEGIN
dbms_scheduler.create_group(group_name =>,
group_type =>,
MEMBER =>,
comments =>);
END;
drop_group
删除组
The ADD_GROUP_MEMBER and REMOVE_GROUP_MEMBER procedures can be used to maintain the member list of the group. The following example adds the destination created in the previous section to the destination group.
BEGIN
DBMS_SCHEDULER.add_group_member(
group_name => 'test_db_group',
member => 'test_credential@rac1_rac1_dest');
END;

add_group_member
为组添加成员
remove_group_member
