篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了EBS 并发请求 计划 fnd_conc_release_classes相关的知识,希望对你有一定的参考价值。

EBS并发请求中有可以设置计划用以定时运行,计划存储在 fnd_conc_release_classes 表中,通过release_class_id与请求表fnd_concurrent_requests关联。

详细信息如下:


RELEASE_CLASS_ID: 主键,与fnd_concurrent_requests关联.

CLASS_TYPE: contains value 'P' for "Periodic" schedules, 'S' for "on Specific Days" schedules and 'X' for "advanced schedules".  P:定期,S:在特定日期,X:高级

DATE1: start date of the schedule ("Start at" field in the form) 起始日期

DATE2: end date of the schedule ("End at" field in the form), as fnd_concurrent_requests.resubmit_end_date 终止日期

CLASS_INFO: this is the most interesting field as it contains all the information needed for rescheduling. The format of the field depends on the type of schedule. 因计划类型的不同,数据格式也随之出现差异.


"PERIODIC" schedule: 定期

In case of Periodic schedule fnd_conc_release_classes.CLASS_INFO field contains values like "2:D:S" or X:Y:Z where:

X – number of months/weeks/days/hours/minutes the request has to be rescheduled from prior run.

Y – contains a single letter representing units

"M" – months;

"D" – days;

"H" – hours;

"N" – minutes;

(there is no representation of "weeks" option. If you specify interval in weeks, it’s automatically calculated and stored in "days").

Z – contains a single letter to represent if the rescheduling has to be done from start or from completion of the prior run

S – from the start of the prior run;

C – from the completion of the prior run.

Some samples:

30:N:S – Repeat every 30 minutes from the start of the prior run

5:N:C – Repeat every 5 minutes from the completion of the prior run

12:H:S – Repeat every 12 hours from the start of the prior run

It’s interesting that information about intervals of periodic schedules is duplicated infnd_concurrent_requests table fields RESUBMIT_INTERVAL, RESUBMIT_INTERVAL_TYPE_CODE and RESUBMIT_INTERVAL_UNIT_CODE.


"ON SPECIFIC DAY" schedule: 在特定日期

In case of on Specific Day schedule fnd_conc_release_classes.CLASS_INFO field contains values like "000010000000000000000000000000010000000" – a 39 character value consisting of 0 and 1. The idea is that the placement of 1-s represent the options selected through form:

1-s at places 1 to 31 – represent dates, when request has to be run, eg, if the 10th character is "1" – the request is scheduled to run on 10th day of each month;

character "1" at the 32nd position – specifies that the request has to be run at the last day of each month;

1-s at places 33 to 39 – specifies days of week (Sunday – Saturday)the request has to be run. if the 33rd character is "1" – the request is scheduled to run each Sunday, if 34th – on Monday and so on.

Some samples:

000000000000000000000000000000000000001 – Days of week: Sa

111111111000000000000000000000000111110 – Dates: 1 2 3 4 5 6 7 8 9. Days of week: Mo Tu We Th Fr

000000000000000000000000000000010000000 – Last day of month
