Change Job Schedule Entry (CHGJOBSCDE)
| Where allowed to run: All environments (*ALL) Threadsafe: No |
Parameters Examples Error messages |
The Change Job Schedule Entry (CHGJOBSCDE) command allows you to change an entry in the job schedule.
The job schedule entry contains all of the information needed to automatically submit a batch job. You can use this command to change:
- The command the job runs
- The date and time at which a job is scheduled to run
- The recovery action the system takes if the job cannot be submitted at the scheduled time
- The job description and user profile under which the job is run
- The job queue on which the job is placed when it is submitted
- The message queue to which messages are sent
Each job schedule entry is identified by the job name, which is specified for the JOB parameter of this command, and an entry number, which is assigned by the system when the entry is added. The message sent when an entry is added contains the entry number. If there is more than one entry with the same job name, you may need to specify the number when changing the entry using this command, removing the entry using the Remove Job Schedule Entry (RMVJOBSCDE) command, or when holding or releasing the entry using the Hold Job Schedule Entry (HLDJOBSCDE) or Release Job Schedule Entry (RLSJOBSCDE) command. You can use the Work with Job Schedule Entries (WRKJOBSCDE) command to show or print entries.
More information is in the Work management topic collection in the IBM i Information Center at http://www.ibm.com/systems/i/infocenter/.
Restrictions:
- The issuer of this command must be running under a user profile which is the same as the job user identity of the job schedule entry being changed, or the issuer of the command must be running under a user profile which has job control (*JOBCTL) special authority.
The job user identity is the name of the user profile by which a job is known to other jobs. More information about the job user identity is in the Work management topic collection in the IBM i Information Center at http://www.ibm.com/systems/i/infocenter/.
- To use this command, you must have:
- use (*USE) authority to the command specified by the Command to run (CMD) parameter and execute (*EXECUTE) authority to the library containing that command.
- use (*USE) authority to the job description (JOBD) and execute (*EXECUTE) authority to the library containing that job description.
- use (*USE) authority to the job queue (JOBQ) and execute (*EXECUTE) authority to the library containing that job queue. Authority to the job queue cannot come from adopted authority.
- use (*USE) authority to the user profile (USER) that the job is to run under.
- use (*USE) and add (*ADD) authority to the message queue (MSGQ), and execute (*EXECUTE) authority to the library containing that message queue. Authority to the message queue cannot come from adopted authority.
- change (*CHANGE) authority to object QDFTJOBSCD, type *JOBSCD, in library QUSRSYS and execute (*EXECUTE) authority to library QUSRSYS.

Job name (JOB)
Specifies the name of the job schedule entry.
This is a required parameter.
- name
- Specify the name of the job schedule entry that you want to change.
| Top |
Entry number (ENTRYNBR)
Specifies the number of the job schedule entry you want to change. The message sent when an entry is successfully added contains the entry number. You can also determine the entry number by using the Work with Job Schedule Entries (WRKJOBSCDE) command. Press F11 from the Work with Job Schedule Entries display to show the entry numbers of the selected entries.
- *ONLY
- Only one entry in the job schedule has the job name specified for the JOB parameter. If *ONLY is specified and more than one entry has the specified job name, no entries are changed and an error message is sent.
- 000001-999999
- Specify the number of the job schedule entry you want to change.
| Top |
Command to run (CMD)
Specifies the command that runs in the submitted job. The IBM-supplied default routing program QCMD must be used when the job is started or the job will not run. Because the command you specify is used for the request data, the value specified for the RQSDTA parameter in the job description is ignored. The command you specify is syntax-checked when the entry is added.
- command-string
- Specify a maximum of 512 characters.
| Top |
Frequency (FRQ)
Specifies how often the job is submitted to run.
- *SAME
- The value does not change.
- *ONCE
- The job is submitted once.
- *WEEKLY
- The job is submitted on the same day or days of each week at the scheduled time.
- *MONTHLY
- The job is submitted on the same day or days of each month at the scheduled time.
If you specify *MONTHLY and a month does not contain the day specified for the SCDDATE parameter, the job is not run that month. For example, if SCDDATE(01/31/93) and FRQ(*MONTHLY) are specified, the job will run on 01/31, 03/31, 5/31, 7/31, 8/31, 10/31 and 12/31, but will not run in February, April, June, September, or November. To submit a job on the last day of every month, specify SCDDATE(*MONTHEND).
If you specify *MONTHLY and your system or your job is configured to use Julian date format, the job is submitted to run on the day of the month that it would run if the system or job did not use Julian date format.
| Top |
Schedule date (SCDDATE)
Specifies the date on which the job is submitted to run.
If your system or your job is configured to use the Julian date format, *MONTHSTR and *MONTHEND are calculated as if the system or job did not use the Julian date format.
- *SAME
- The value does not change.
- *CURRENT
- The job is submitted on the current date.
- *MONTHSTR
- The job is submitted on the first day of the month. If you specify *MONTHSTR, and if today is the first day of the month and the time you specify on the SCDTIME parameter has not passed, the job is submitted today. Otherwise, the job is submitted on the first day of the next month.
- *MONTHEND
- The job is submitted on the last day of the month. If you specify *MONTHEND, and if today is the last day of the month and the time you specify on the SCDTIME has not passed, the job is submitted today. Otherwise it is submitted on the last day of the next month.
- *NONE
- No date is specified for a job to be submitted. When SCDDATE(*NONE) is specified, a value other than *NONE must be specified for SCDDAY.
- date
- Specify the date in the job date format.
| Top |
Schedule day (SCDDAY)

The SCDDATE and SCDDAY parameters are mutually exclusive.
If today is the day of the week specified for this parameter and the time specified for the SCDTIME parameter has not passed, the job is submitted today. Otherwise, the job is submitted on the next occurrence of the specified day. For example, if SCDDAY(*FRI) and SCDTIME(12:00:00) are specified, and you are adding this job schedule entry at 11:00 a.m. on a Friday, the job is submitted today. If you are adding the entry at 4:00 p.m. on a Friday, or at 11:00 a.m. on a Monday, the job is submitted the following Friday.
Single values
- *SAME
- The value does not change.

- *SAME
- The value does not change.
- *CURRENT
- The job is submitted at the current time. If you specify SCDTIME(*CURRENT) and SCDDATE(*CURRENT), the job is immediately submitted to the job queue specified.
- time
- Specify the time you want the job to be submitted. The time is specified in 24-hour format and can be specified with or without a time separator:
- Without a time separator, specify a string of 4 or 6 digits (hhmm or hhmmss) where hh = hours, mm = minutes, and ss = seconds. Valid values for hh range from 00 to 23. Valid values for mm and ss range from 00 to 59.
- With a time separator, specify a string of 5 or 8 digits where the time separator specified for your job is used to separate the hours, minutes, and seconds. If this command is entered from the command line, the string must be enclosed in apostrophes. If a time separator other than the separator specified for your job is used, this command will fail.

Recovery action (RCYACN)
Specifies the recovery action to be taken if the job cannot be submitted at the designated time because the system is powered down or in restricted state. The action specified for this parameter occurs at the next IPL or when the system comes out of restricted state.
Jobs submitted during IPL or when the system comes out of restricted state are submitted in the same order that they would have been had the jobs been submitted at the times specified in the job schedule entries. If multiple occurrences of a recurring job are missed, the job is submitted only once. The first missed occurrence of a recurring job is used to order the jobs. The next occurrence of the job is calculated from the current date.
Since the scheduler portion of IPL need not be complete for the IPL of the system to be complete, other jobs may start on the system before all of the jobs have been submitted.
This parameter does not apply:
- When a job is released after being held at the date and time it was to be submitted
- When the date and time at which a job is to be submitted passes because of changes to date and time system values
- *SAME
- The value does not change.
- *SBMRLS
- The job is submitted in the released state (RLS).
- *SBMHLD
- The job is submitted in the held state (HLD).
