EBS Concurrent Request Schedule Options

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 runS – 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 run5:N:C – Repeat every 5 minutes from the completion of the prior run12:H:S – Repeat every 12 hours from the start of the prior runIt’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: Sa111111111000000000000000000000000111110 – Dates: 1 2 3 4 5 6 7 8 9. Days of week: Mo Tu We Th Fr000000000000000000000000000000010000000 – Last day of month

最后，奉上一段SQL:
