Description of "Figure 13-1 The scheduling process"

13.2.1 Understanding the Job Scheduler

了解 Job Schduler

When you schedule a batch process to run through the Scheduler, you can also add a recurrence pattern to the job, which means that the job will restart at the intervals that you define, such as once a week, once a month, or once a year. You can also specify how many times you want the job to run before it ends, or you can define a date after which the job will no longer run.

用Scheduler设置批处理job时，可以设置job运行频率，具体间隔可以是一周，一月或者一年。也可以job总共运行的次数，或者job运行的截至日期。

You schedule jobs in the local time of the server on which the job will run. For example, when you schedule a job, you might select the version that specifies the eastern time zone to run jobs in eastern standard time (EST).

job运行都以服务器上的时间为准，可以将job运行时间指定为特定时区。

13.2.2 Prerequisite

条件

To use a server's time zone, you must first specify the time zones that you want to use. To do this, copy the Scheduler processing options (version ZJDE0001 on the Work with Versions form), and modify them according to your needs. If you use more than one time zone, you should modify the processing options to display the Work with Versions form each time that you invoke the Schedule Jobs application. That way, you can select the correct version for the time zone in which you want to schedule the job.

如果要改变job的运行时区，需要先设置。拷贝Scheduler的标准运行选项(ZJDE0001版本，on the Work with Versions form)，按需求改时区。需要在多时区下运行时，需要在每次运行job前选择相应时区。

13.2.3 Forms Used to Work with the Job Scheduler

Job Scheduler相关Form

13.2.4 Setting Processing Options for the Job Scheduler

设置Job Scheduler运行项

Processing options enable you to specify the default processing for programs and reports.

可以设置程序和报表的默认运行项

13.2.4.1 Display

13.2.5 Scheduling a Job

设置一个schedule job

Access the Work With Scheduled Jobs form. On the Work with Versions form, double-click the version that specifies the time zone in which the scheduled job will run.

进入Work With Scheduled Jobs表, 在Work with Versions，双击选中job运行时区。

1. On the Work With Scheduled Jobs form, click Add.    在表单Work With Scheduled Jobs，点击Add

2. On the Scheduling Information Add form, in the Scheduled Job Name field, enter a name that uniquely identifies to the system and the user of a scheduled job.

   Use this name to indicate the job function, such as Monthly Close or Nightly Back Up.  进入表单Scheduling Information Add，选择scheduled Job Name字段，输入系统识别的属性唯一的job名称，以及job用户，名称要表明job的功能，例如月结，晚间备份等

3. In the Scheduled Job Status, determine the status of the scheduled job. Job的状态标注于Scheduled Job Status字段

   As long as the status is active, the Scheduler determines if the job should be submitted to the server for execution. When the scheduled end date for the job has been reached, the status changes toNot Active. To stop the Scheduler from considering the job for submission, you can change the status toNot Active (or suspended) at any time prior to the end date. You can reactivate the job if you want the Scheduler to include the job again, but you can reactivate a job only if the end date is in the future.  当Job状态是active时，Scheduler决定job是否该提交执行。当job到期后，其状态变成Not Active。Job未到期之前，可以在任意时间将job的状态改为Not Active（或者挂起）状态，不向系统提交此job。也可在Job未到期之前，讲Not Active的job状态改做Active，提交某job。

4. In the Scheduled Batch Application, specify the object name of the report that the Scheduler submits to the server. Scheduled Batch Application字段表明scheduler提交给系统时，报告的对象名称。

5. In the Scheduled Version, specify the version of the report that is scheduled to run. A version identifies a specific set of data selections and sequencing settings that the batch job uses. Scheduled Version字段表明已schedule的报告的版本。版本代表着一组数据集以及批处理job的顺序。

6. In the Scheduled Start Date/Time, determine the next date on which the Scheduler submits the scheduled job to the server for execution, and then click OK. Scheduled Start Date/Time字段表明下一次scheduler job提交到系统执行的时间。

You can also use advanced options to specify whether you want the system to resubmit a job if it ends in error or if you want to change job expiration specifications.

可以通过高级选项重写job属性值，例如job运行地点及环境. 也可以通过高级选项定义job运行失败后是否再次提交，更改job过期准则.

You can define whether to log errors to the jde.log or jdedebug.log, and whether you want the system to override printer locations and job queues. You can also add a report interconnect to a job if you want to pass parameters to it.

定义是否将错误写入jde.log或者jdedebug.log，或者系统是否要重定义打印机或者job队列。如果想给job传递参数，可以增加一个报表互联值.

13.3.2 Forms Used to Work with Advanced Scheduling Options

与Work with Advanced Scheduling Options相关的表单

13.3.3 Overriding the Environment

重写环境

Access the Scheduling Advanced Options form. Select the Launch Overrides tab. 进入Scheduling Advanced Options界面，选择Launch Overrides

A situation might exist in which you need to override an environment. For example, you would override the environment if the environment in which you want to run the job is not available or is different from the environment that you were logged into when you scheduled the job.

有时候需要重写环境，例如，当需要跑job的环境无法使用或者与你登录定义scheduled job时的环境不同。

13.3.4 Overriding Job Expiration Specifications

重写job过期规则

Access the Scheduling Advanced Options form. Select the Job Expirations tab.

进入Scheduling Advanced Options表达那，选择Job Expirations.

Job expiration specifications ensure that servers do not become overloaded with unexpired jobs. If necessary, you can override job expiration specifications so that the job never expires, or expires after a certain number of minutes.

Job 过期规则保证server不会因为过了制定时间而未执行的job而负载太重。如果需要，可以设置job永不过期，或者在多少分钟后过期。

For example, suppose you schedule a job to run at midnight and another job for 1:00 a.m., but the server goes down and probably will not come back up again before the jobs are scheduled to run. In this case, you can specify that the first job, which you scheduled to run at midnight, expires in 30 minutes (12:30 a.m.), so that if the server does not come back up within 30 minutes, the job expires.

例如，设置某job是在午夜运行，另一个job是在早上1点运行，但是server停掉了，并且无法在job运行时启动，这种情况下，可以制定第一个在午夜运行的job在30分钟后过期，这样，如果server在12：30还未启动，那么这个job就过期不需要再执行。

13.3.5 Defining When the Scheduler Resubmits a Job

定义scheduler何时再提交job

Access the Scheduling Advanced Options form.

进入Scheduling Advanced Options表单

You can define when the Scheduler resubmits jobs. This feature is useful if a job ends in error, for example, because the Scheduler will submit the job after a certain period of time.

可定义scheduler何时重新提交job. 此选项多用于job运行失败的情况，因为scheduler会在一定时间后重新提交这个job.

To avoid the use of system resources, you can limit the number of times that a job can be resubmitted. You also can have the Scheduler check for connection errors or runtime errors when the job runs. Connection errors occur when the system fails to connect to the server to submit the job. Runtime errors occur when the server on which the job is running places the job in an error state. You can set up the system to monitor for both cases.

为避免占用系统资源，可以控制job重新提交的时间。在job运行期间，scheduler会检查链接错误和运行错误。链接错误是指在提交job时，无法链接到服务器。运行错误是指服务器将正在运行都job置为错误状态。可以在系统中设置监控这两项.

To define when the system resubmits jobs:

定义系统何时重新提交job:

1. On the Scheduling Advanced Options form, select the Job Resubmission tab. 在Scheduling高级选项，选择Job Resubmission.

2. Specify the number of minutes that elapse before the job continues or terminates, and then activate one of the following options: job继续运行或者终止前的分钟数，随后激活一下选项：

   • Let the job continue.  Job继续运行

   • Terminate the job.  终止job

   • Terminate the job and resubmit.  终止job，重新提交

3. If you want to terminate the job and resubmit it after a certain period of time, select the terminate the job and resubmit after option, and enter the number of minutes that you want to elapse before the system resubmits the job.  如果想要终止某job并且在一段时间后重新提交，选择终止job再重新提交选项，输入job再提交前的时间间隔.

4. Select one of the following options that apply when the job ends in error: 当job运行结果为错误时，选择如下选项：

   • Do nothing.  无动于衷

   • Resubmit immediately. 马上重新提交

   • Resubmit after.  稍后重新提交

5. Specify whether you want the system to check for connection errors, runtime errors, or both.  制定系统是否检查链接错误，运行错误.

6. In the Max Number of Job Resubmissions field, specify the maximum number of times that you want the job to be resubmitted. 在Max Number of Job Resubmissions字段，制定job重新提交的次数.

7. Click OK. 点击OK.

13.3.6 Overriding Batch Application Specifications

重写批处理规则

Access the Scheduling Advanced Options form.

进入Scheduling Advanced Options表单

You can specify if you want errors written to the jde.log. If you want errors written to the jdedebug.log, you can set the trace level to determine what types of errors to include in the log.

可定义是否将错误写入jde.log. 如果要将错误写入jdedebug.log, 可以设置log追踪级别，决定什么样的错误包含在log中。

You can also override the printer at which a report is printed. This feature is useful if a specific printer is down or if you want to print a report to a printer other than the default. You can specify whether a job should be printed immediately upon completion or held in the job queue to be printed later.

可以重写打印机。此功能应用于某打印机不能用或者要用非默认打印机的其他打印机. 可以定义某job在执行完成后及时打印还是在job队列等待稍后打印.

Also, you can override the queue to which the output of a submitted job is sent. If you want to pass parameters to a particular batch job, you can attach a report interconnect through Batch Application Specifications.

当然，也可以重新定义提交了的job发送到哪个队列重。如果想给某批处理job传递参数，可以依照批处理规则附加报告互联。

To override batch application specifications:

重写批处理规则:

1. On the Scheduling Advanced Options form, select the Batch Application Overrides tab. 在Scheduling Advanced Options表单，选择Batch Application Overrides

2. Select one or more of the following options: 单选或多选以下选项:

   • Jde.log

   • Jdedebug.log

     If you select jdedebug.log, you must also select the jde.log option.  如果选择jdedebug.log，一定要同时选择jde.log.

3. Complete these fields: 完成一下字段：

   • UBE Logging Level    UBE日志级别

     If you select jdedebug.log, you can set a trace level to log certain levels of errors. 如果开启jdedebug.log，设置log对错误的追踪级别.

   • Printer Name  打印机名

     Enter the name of the printer to which you want to print the report that the job generates. If you want to use a default printer, specifyDEFAULT. 选择要打印job的打印机，如果要选择默认打印机，选择DEFAUL.

   • Print Immediate 马上打印

     If you want the job output to be sent to the printer immediately, select this option. 如果想要job输入很快发送到打印机，选择此选项.

   • Job Queue  任务队列

     Enter the name of the job queue to which you want the job output sent. job输入后，发送到队列的名称.

4. Click OK.  点击OK

13.3.7 Adding Values to a Report Interconnect

给报告互联赋值

Access Work With Scheduled Jobs form.

进入Work With Scheduled Jobs表单.

You can add values to be passed through a report interconnect into a batch process when that batch process is launched. The batch process must first contain a report interconnect.  当批处理程序开始时，可以通过报告互联给批处理传值，但此批处理必须先包含报告互联。

1. On the Work With Scheduled Jobs form, select the job and then select Advanced Options from the Row menu. 在Work With Scheduled Jobs表单，选定job，然后从Row按钮选择Advanced Options

2. On the Scheduling Advanced Options form, select Parameters from the Form menu. 在Scheduling Advanced Options，从Form按钮选择参数.

3. On the Report Interconnect form, enter the values that you want to pass to the batch process when the process runs.  在Report Interconnect表单，输入需要传递给批处理程序的值.

4. Click OK. 点击OK.

13.4.1 Understanding Job Schedule Reviewing

理解Job Schedule回顾

When you schedule a job that includes a recurrence pattern, the system creates a set of schedule records, or instances, for the job in the F91320 table. The F91320 table indicates the times and dates that the job will run. You can review these instances and their statuses, and also change the scheduled job information. For example, you can change the location at which you want a job to process, delete a job instance, or override any advanced functions.

当设置一个多次执行的job，系统就会为表F91320生成一系列schedule记录或者实例. 表F91320记录job运行的具体时分. 可以查看实例状态，改变scheduled job信息。例如，改变job执行的地址，删除一个job实例，重写任意高级功能。

13.4.2 Forms Used to Review the Job Schedule

13.4.3 Reviewing All Job Schedules

13.5.1 Understanding the Scheduler Server

The Scheduler server is a process that performs two distinct functions: it launches all jobs at the scheduled times, and it monitors each job's progress and ending state. These functions are started by a JDENET message, as defined in the following kernel type in the jde.ini file:

Scheduler服务器是一个进程，有两个主要功能：按照时间开启所有scheduler job，检测job的运行状态和运行结果。这些功能由JDENET开始，在jde.ini中做如下定义:

[JDENET_KERNEL_DEF10]
dispatchDLLName=jdekrnl.dll
dispatchDLLFunction=_JDEK_DispatchScheduler@24
maxNumberOfProcesses=1
beginningMsgTypeRange=2001
endingMsgTypeRange=2256
newProcessThresholdRequests=0
numberOfAutoStartProcesses=1

The Scheduler launches batch processes in a server, environment, and user combination, based on the information in the F91300 table. After the Scheduler is started, JDENET keeps it in a wait state by calling the Scheduler dispatch function every minute with an idle message. This idle message enables the Scheduler process to check whether it should launch a job or monitor the jobs that are running. In addition, JDENET sends the Scheduler any message sent from the workstation (for example, messages that new job schedules were added).

Scheduler依据表F91300中的信息在特定的服务器，环境和用户下启动批处理。scheduler开始运行后，JDENET每分钟给scheduler的分配功能发送一条闲置信息，使服务器保持在等待的状态。这条闲置信息使scheduler进程检查是否需要启动一个job或者监测正在运行的job。除此之外，JDENET也把工作台发送过来的信息转送给scheduler （例如，添加新的scheduler job信息）

You can stop, reset, restart, and refresh the Scheduler server. For example, if the server goes offline, it needs to be reset. You can also modify the server and monitor sleep time, specifying how many seconds you want JDENET to wait until it checks to see if it needs to initialize, or wake up, the Scheduler server.

可以对scheduler服务器停止，重设，重启，刷新等。例如，如果服务器下线，则需要重新设置。还可以更改服务器和监控器的休眠时间，指明JDENET等待多少秒后去检查是否需要初始化或者启动scheduler服务器。

You also might encounter situations for which you need to activate or deactivate the Job Launcher or Job Monitor. For example, you might need to take down the servers to which you submit jobs and for which you want to avoid unnecessary connection errors when jobs are submitted.

有时候也许要启动或者禁止Job启动器和监控器。例如，有时候需要记录下来提交job的服务器以及job提交以后所产生的不必要的连接错误。

You can also change the jde.ini file to enable the Scheduler to restart automatically by changing thenumberOfAutoStartProcesses line. If you enable this feature, and the server on which the Scheduler server is running comes down, the Scheduler server automatically restarts when the server comes back up, instead of having to be restarted manually. When the Scheduler server restarts, the Scheduler checks the F91320 table to determine if it should restart on that server. If not, the Scheduler shuts down.

也可以修改jde.ini文件中的thenumberOfAutoStartProcesses，使scheduler可自动重启。如果开启此特性，而运行scheduler的服务器宕机后，当服务器重新启动时，scheduler也会相应重启，不必再手动重启scheduler。当scheduler服务器重启后会检查表F91320，看自己是否需要重启，如果不需要，scheduler就会自行关闭。

JDENET handles the calls to initialize the Scheduler server. The JDENET process either sends a message to initialize the Scheduler to launch a job if it receives a message that table F91320 has changed, or it sends an idle message if no change is detected. For faster response time, you can decrease the number of seconds that you want JDENET to wait until it checks to see if table F91320 has changed.

JDENET处理scheudler初始化的调用。如果表F91320有变化，JDENET进程向scheduler发送一条初始化job信息；如果表没有改变，JDENET进程则向scheduler发送一条闲置信息。如果想加快响应时间，则可以减少JDENET监测表F91320是否变化的间隔时间。

13.6.1 Understanding Daylight Savings Rules

Daylight savings rules tell the system how each locale implements its daylight savings time. You associate a daylight savings rule to each user profile depending on the geographic location of the user. In addition, you can assign a daylight savings rule to a batch job that is scheduled to run in the Scheduler. The Scheduler uses these daylight savings rules, along with time zone information, to determine when batch jobs run on a particular server.

You can only associate one daylight savings rule with a user or scheduled job. However, in the Daylight Savings Time program (P00085), you can create multiple records for the same rule to account for variations in the daylight savings time from one year to the next. For example, if the daylight savings time period for a region is the same from 2008 through 2010, and then changes for 2011, you can create one daylight savings time rule that contains the following two records:

• DST Rule1–2008–Start and end dates for the daylight savings period

• DST Rule1–2011–Start and end dates for the daylight savings period

When the DST Rule1 in this example is associated to a user or scheduled job, JD Edwards EnterpriseOne uses the 2008 daylight savings record to determine the time until 2011, when it will automatically use the daylight savings time dates defined in the rule for 2011.

In the Southern Hemisphere, daylight saving time starts in one year and ends in another. When you set up a daylight savings time rule, the year that you enter for the daylight savings time rule must be the year in which the daylight savings time begins.

13.6.2 Prerequisites

The daylight savings time functionality that enables you to create multiple records for one rule is a JD Edwards EnterpriseOne Tools feature that is applicable to the JD Edwards EnterpriseOne Applications 8.12 and 9.0 releases. This feature comes automatically with the 9.0 release. However, to obtain this feature for the 8.12 release, you must download an electronic software update (ESU). On My Oracle Support, access SAR 8414822 to locate the ESU. In addition to the Daylight Savings Rule program changes, the ESU contains instructions on performing a table conversion to convert existing daylight savings rule data from the F00085 table to the F00085A.

13.6.3 Adding Daylight Savings Rules

From the Job Scheduler menu (GH9015), select Daylight Savings Rules (P00085).

1. On Work With Daylight Savings Rules form, click Add.

   • Description

     Enter a description of the daylight savings rule.

3. In the Rule Type area, select one of these options to indicate the method that you want to use to determine the daylight savings rule dates:

   • y Day of Week Instance

     Select this option to enter start and stop dates for daylight savings on a certain day of the week for a certain month, such as the first Sunday of April to the first Sunday of October.

   • By Day of the Month

     Select this option to enter start and stop dates for daylights savings on a certain day of a certain month, such as April 3 to October 10.

4. Depending on the method that you chose, complete the remaining fields to specify when daylight savings starts and ends, and then click OK.

13.6.4 Adding an Additional Daylight Savings Record to a Daylight Savings Rule

To add another set of dates to accommodate for a change in the daylight savings period, you can add another record that contains new dates to an existing daylight savings rule.

From the Job Scheduler menu (GH9015), select Daylight Savings Rules (P00085).

1. On the Work With Daylight Savings Rules form, click Copy.

2. On the Add Daylight Savings Rule form, complete these fields:

   Note:

   Do not modify the Rule Name field because doing so will create a new rule that you will have to reassign to a user profile or scheduled job.

   • Daylight Savings Effective Year.

     Enter the year in which the daylight savings rule begins.

   • Description.

3. In the Rule Type area, select one of these options to determine which method that you want to use to determine the daylight savings rule dates:

   • By Day of Week Instance.

   • By Day of Month.

4. Depending on the method that you chose, complete the remaining fields to specify when daylight savings starts and ends, and then click OK.

13.6.5 Revising Daylight Savings Rules

When you revise an existing daylight saving time rule, you cannot change the rule name or the year that the daylight savings rule takes affect.

From the Job Scheduler menu (GH9015), select Daylight Savings Rules (P00085).
