Hi

Can anybody explain about the "Job description" *JOBD?

Thanks

Re: Jobd

A job description is used to control "stuff" for a batch/interactive job.

1. Library List
2. Job Queue
3. Out Queue
4. run priority
5. etc.....

It can also be used in auto start jobs to actually call a program when a subsystem starts.



The Create Job Description (CRTJOBD) command creates a job description
object that contains a specific set of job-related attributes that
can be used by one or more jobs. The attributes determine how each
job is run on the system. The same job description can be used by
multiple jobs. The values in the job description are usually used
as the default values of the corresponding parameters in the Batch
Job (BCHJOB) and Submit Job (SBMJOB) commands when their parameters
are not specified.

The values in the job description can be overridden by the values
specified in the BCHJOB and SBMJOB commands.

Restrictions:

To use this command, the user must have object operational authority
for the user profile specified on the USER parameter (if any); that
is, the user must have the authority to start a job on behalf of that
user.

The user must also have *ADD authority for the library where the job
description is placed. To create a job description with an accounting
code (ACGCDE) parameter other than *USRPRF, the user must have *USE
authority to the Change Accounting Code (CHGACGCDE) command.
Required Parameter

JOBD
Specifies the qualified name of the job description being created.
The name of the job description can be qualified by one of the
following library values:

*CURLIB: The job description is created in the current library for the job.
If no library is specified as the current library for the job, the QGPL
library is used.

library-name: Specify the name of the library where the job description is created.

job-description-name: Specify the name of the job description being created.

Optional Parameters

USER
Specifies the name of the user profile associated with this job description.
The names QSECOFR, QSPL, QDOC, QDBSHR, QRJE, QTSTRQS, and QDFTOWN are not
valid entries for this parameter.

*RQD: A user name is required to use the job description. For work station
entries, you must enter your password when you sign on at the work station;
the associated user name becomes the name used for the job. *RQD is not
valid for job descriptions specified for job entries that start
automatically, or for those used by the BCHJOB command. It is valid on the
SBMJOB command only if USER(*CURRENT) is specified.

user-name: Specify the user name that identifies the user profile associated
with batch jobs that use this job description. For interactive jobs, this
is the default user name used when signing on without entering a password.


JOBQ
Specifies the qualified name of the job queue on which this job is placed.
The name of the job queue can be qualified by one of the following library

values:

*LIBL: All libraries in the job's library list are searched until the
first match is found.

*CURLIB: The current library for the job is searched. If no library
is specified as the current library for the job, the QGPL library
is used.

library-name: Specify the name of the library to be searched.

QBATCH: The QBATCH job queue is the queue on which the jobs are placed.

job-queue-name: Specify the qualified name of the job queue that is
associated with this job description.

If the job queue does not exist when the job description is created,
a library qualifier must be specified because the name of the qualified
job queue is retained in the job description.


JOBPTY
Specifies the scheduling priority for each job that uses this job
description. The highest priority is 1 and the lowest priority is 9.
More information on this parameter is in commonly used parameters.
5: The scheduling priority that any job using this job description is 5.

scheduling-priority: Specify the scheduling priority for any job using
this job description. Valid values range from 1 through 9.


OUTPTY
Specifies the output priority for spooled files that are produced
by jobs using this job description. The highest priority is 1 and
the lowest priority is 9. More information on this parameter is in
commonly used parameters.

5: The output priority for spooled files produced using this job
description is 5.

output-priority: Specify the priority of spooled files produced using
this job description. Valid values range from 1 through 9.


PRTTXT

Specifies up to 30 characters of text to be printed at the bottom of each
page of output. More information on this parameter is in commonly used
parameters.

*SYSVAL: The system value, QPRTTXT, is used.

*BLANK: Text is not specified.

'print-text': Specify the character string that is printed at the bottom
of each page. Up to 30 characters can be entered, enclosed in apostrophes.


ACGCDE
Specifies the accounting code used when logging system resource use for a
job having this job description. To specify an accounting code other than
*USRPRF, the user must have *USE authority for the Change Accounting Code
(CHGACGCDE) command.

Note: If the job is submitted by the SBMJOB command,
the submitter's accounting code is used.


*USRPRF: The accounting code for jobs using this job description is
obtained from the job's user profile.

*BLANK: An accounting code of 15 blanks is assigned to jobs that
use this job description.

accounting-code: Specify the character string that is used as the
accounting code for jobs that use this job description
and have accounting statistics logged in the system
accounting journal QSYS/QACGJRN. If less than 15
characters are entered, the string is padded on the
right with blanks. Note that the character string '*USRPRF'
is considered a special value, and cannot be used as an
accounting code on this command.

RTGDTA

Specifies the routing data that is used with this job description to
start jobs. The routing data is used to determine the routing entry
in the subsystem description that identifies the program where the
job runs.

QCMDI: The default routing data QCMDI is used by the IBM-supplied
interactive subsystem to route the job to the IBM-supplied
control language processor QCMD in the QSYS library.

*RQSDTA: Up to the first 80 characters of the request data specified
in the RQSDTA parameter are used as the routing data for the job.

'routing-data': Specify the character string, enclosed in apostrophes,
that is used as the routing data for jobs that use this
job description. For example, the value QCMDI is the
routing data used by the IBM-supplied interactive subsystem
(QINTER) to route interactive jobs to the IBM-supplied control
language processor QCMD. Up to 80 characters can be entered.


RQSDTA

Specifies the request data that is placed as the last entry in the job's
message queue for jobs using this job description. For example, when a
CL command is supplied as request data on a Submit Job (SBMJOB) command,
it becomes a message that can be read by the control language processor,
QCMD (if the submitted job is routed to QCMD).

*NONE: No request data is placed in the job's message queue.

*RTGDTA: The routing data specified in the RTGDTA parameter is placed
as the last entry in the job's message queue.

'request-data': Specify the character string that is placed as the last
entry in the job's message queue as a single request.
Up to 256 characters can be entered, enclosed in apostrophes.
When a CL command is entered, it must be enclosed in single
apostrophes, and where apostrophes would normally be used
inside the character string, double apostrophes must be used
instead.


SYNTAX

Specifies whether requests placed on the job's message queue are checked
for syntax as CL commands. When syntax checking is specified, the commands
are checked for syntax as they are submitted rather than when the job is
run, thus providing an earlier diagnosis of syntax errors. If checking
is specified, the message severity that causes a syntax error to end
processing of a job is also specified. More information on this parameter
is in commonly used parameters.


*NOCHK: The request data is not checked for syntax as CL commands.
If the message severity is specified, it is used only when
the job description is used by a job command that also has
RQSDTA(*) specified and the requests are CL commands.

message-severity: Specify a value, ranging from 00 through 99,
that specifies the lowest message severity that can cause running
of a job to end. The request data is checked for CL command syntax;
if a syntax error occurs that has severity equal to or greater
than the error message severity specified here, the running of the
job is suppressed.


INLLIBL
Specifies the first user portion of the library list that is used
for jobs using this job description.

Note: Duplicating libraries in the library list is not allowed.


More information on the use of library lists is in the CL
Programming book.

*SYSVAL: The system default user library list is used for
jobs that use this job description. The default user
library list contains the library names that were specified
in the system value QUSRLIBL at the time that a job using this
job description is started.

*NONE: The user portion of the first library list is empty; only
the system portion is used.

library-name: Specify the names of one or more libraries that
are in the user portion of the library list for jobs that use
this job description. No more than 25 names can be specified;
the libraries are searched in the same order as they are
listed here.


ENDSEV
Specifies the message severity level of escape messages that
can cause a batch job to end. The batch job is ended when a
request in the batch input stream sends an escape message
whose severity code is greater than or equal to that specified
here to the request processing program. This parameter value is
compared with the severity of any unmonitored escape message
that occurs as a result of running a noncompiled CL command
in a batch job. More information on message severity is in
commonly used parameters.

30: An escape message resulting from a request in the batch input
stream whose severity is equal to or greater than 30 causes
the job to end.

message-severity: Specify a value, ranging from 00 through 50,
for the message severity of an escape message that results
from a request in the batch input stream and that causes the
job using this job description to end. Because escape messages
typically go up to a severity level of 50, a value of 50 or
lower must be specified for a job to end as a result of an
escape message. An unhandled escape message whose severity
is equal to or greater than the value specified causes the
job to end. More information on message severity is in
commonly used parameters.


LOG
Specifies the message logging values used to determine the
amount and type of information sent to the job log by this job.
This parameter has three elements: the message (or logging)
level, the message severity, and the level of message text.
If no values are specified on this parameter, the values
specified in the job description associated with this job
are used.

Note: If no values are specified for the LOG parameter,
the values 4, 0, and *NOLIST are assumed by the system.


Element 1: Message Level

The first of the three values in the LOG parameter specifies
one of five logging levels ranging from 0 through 4.

Notes:

A high-level message is sent to the program message queue
of the program that received the request or commands being
logged from a CL program.

Several system displays provide a retrieve function (the F9 key)
which gets a logged command into a command line. Commands are not
necessarily logged unless the logging level is set to 3 or 4.
If the logging level is set to 0, 1, or 2, each command
that is completed cannot be retrieved into a command line
because the logging level causes the command to be removed
from the job log. When each command is completed, it cannot
be retrieved into a command line if the message logging level
for the job causes the command to be removed from the job log.
The logging levels are described below:

0 
No data is logged. 

1 
The following information logged: All messages sent to the job's 
external message queue with a severity greater than or equal to 
the message severity specified (this includes the indications 
of job start, job end, and job completion status). 

2 
The following information is logged: 
Logging level 1 information 
All requests entered on a command line and commands being logged 
from a CL program for which messages are issued with a severity 
code greater than or equal to the severity specified 

All messages that are associated with a request entered on a 
command line or a command being logged from a CL program that 
results in a high-level message with a severity greater than or 
equal to the severity specified 

3 
The following information is logged: 
Logging level 1 information 

All requests entered on a command line and commands being 
logged from a CL program 

All messages that are associated with a request entered on a 
command line or a command being logged from a CL program that 
results in a high-level message with a severity greater than 
or equal to the severity specified 

4 
The following information is logged: 
All requests entered on a command line and commands being 
logged from a CL program 

All messages with a severity code greater than or equal to 
the severity specified, including trace messages 

4: A message logging level of 4 is used for job messages 
created when this job description is used.

message-level: Specify the message logging level used for
job messages produced when this job description is used.
Valid values range from 0 through 4.




Element 2: Message Severity

The second of the three values in the LOG parameter specifies
the minimum severity level that causes error messages to be
logged in the job logs of jobs that use this job description.
More information on message severity is in commonly used
parameters.

0: The message severity level is set at 0. Errors that have
a severity code of 0 or greater cause an error message to
be logged in the job log in which the error occurred.

message-severity: Specify the lowest severity level that causes an
error message to be logged in the job's log. Valid
values range from 00 through 99.

Element 3: Message Text Level

The third of the three values in the LOG parameter specifies the level
of message text that is written in the job log or displayed to the user
when an error message is created by the first two values.

*NOLIST: No job log is produced for jobs that use this job description 
         and end normally. If the job ends abnormally 
         (if the end of job code is 20 or higher), a job log is produced. 
         The messages appearing in the job's log contain both message 
         and help text. 

*MSG: Only first-level message text is written to the job log. 

*SECLVL: Both the message and second-level message text of the error 
         message is written to the job log.

For an interactive job, the LOG parameter value on the SIGNOFF
command takes precedence over the LOG parameter value specified
for the job.


LOGCLPGM
Specifies whether the loggable commands that are run in a control
language program are logged to the job log by way of the CL program's
message queue. This parameter sets the status of the job's logging
flag. If *NO is specified, the logging flag status is off and CL
commands are not logged. If *YES is specified and the LOG (*JOB)
value is specified in the Create CL Program (CRTCLPGM) command,
all commands in the CL program that can be logged are logged to
the job log.

For more information on request logging, refer to the LOG parameter
in the CRTCLPGM command description.

*NO: Commands in a CL program are not logged to the job log.

*YES: Commands in a CL program are logged to the job log.


INQMSGRPY
Specifies the way that inquiry messages are answered for jobs
that use this job description. The user can specify that inquiry
messages are to be answered in the usual manner, that a default
reply be issued, or that if certain conditions are met, an answer
is issued to the inquiry based on those conditions. The conditions
met are listed in the system reply list entries; refer to the Add
Reply List Entry (ADDRPYLE) command description for more information.

 
*RQD: An answer is required for any inquiry message that occurs 
      while a job is running under this job description. 

*DFT: The default reply to the inquiry message is sent. 
      If no default reply is specified in the message description 
      of the inquiry message, the system default reply, *N, is used. 

*SYSRPYL: The system reply list is checked to determine whether 
          there is an entry for any inquiry message issued as a 
          result of running a job under this job description. 
          If a match occurs, the reply value in that entry is used. 
          If no entry exists for that message, the inquiry is issued.

PRTDEV

Specifies the name of the default printer device for this job.
If the printer file being used to create the output specifies
to spool the file, the spooled file is placed on the device's
output queue, which is named the same as the device.

Note: This assumes the defaults are specified on the OUTQ
parameter for the printer file, job description, user
profile and workstation.

*USRPRF: The printer device name for jobs using this description 
         is obtained from the user profile of the job at the time 
         the job is started. 

*SYSVAL: The value specified in the system value QPRTDEV is used. 

*WRKSTN: The output queue assigned to the user's work station is used. 

printer-device-name: Specify the name of the printer device that is 
                     used with this job description.

OUTQ

Specifies the qualified name of the output queue.

*USRPRF: The output queue name for jobs using this job description 
         is obtained from the user profile of the job at the time 
         the job is started. 

*DEV: The output queue specified on the PRTDEV parameter is used. 

*WRKSTN: The output queue assigned to the user's work station is used. 


[i]The name of the output queue can be qualified by 
   one of the following library values: [/i]

*LIBL: All libraries in the job's library list are searched 
       until the first match is found. 

*CURLIB: The current library for the job is searched.  
         If no library is specified as the current library 
         for the job, the QGPL library is used. 

library-name: Specify the name of the library to be searched. 

output-queue-name: Specify the qualified name of the default 
                   output queue that is used with this job 
                   description. 

If the output queue does not exist when the job description is 
created, a library qualifier must be specified because the output 
queue name is retained in the job description.

HOLD

Specifies whether jobs using this job description are placed on
the job queue in the hold condition. A job placed on the job
queue in the hold condition is held until it is either released
by the Release Job (RLSJOB) command or canceled by the End Job
(ENDJOB) or Clear Job Queue (CLRJOBQ) command. If the job is
not run before the next power-down of the system, the job
queue can be cleared (and the job ended) when the next initial
program load (IPL) is done.

*NO: Jobs using this job description are not held when they
are put on the job queue.

*YES: The spooled file is held until released by the
Release Spool File (RLSSPLF) command.


DATE

Specifies the date that is assigned to the job that uses
this job description when the job is started.


*SYSVAL: The value in the QDATE system value at the time
the job is started is used as the job date.

job-date: Specify the value that is used as the job date
for the job being started. The format that is
currently specified for the system value QDATFMT
must be used. The QDATFMT system value is in the
Work Management book.


SWS

Specifies the initial settings for a group of eight job
switches used by jobs that use this job description.
Only zeros (off) and ones (on) can be used. These switches
can be set or tested in a CL program and used to control
the flow of the program. For example, if a certain switch
is on, another program could be called. The job switches
may also be valid in other high-level language (HLL)
programs.

00000000: The first setting for the job switches is all
zeros for jobs that use this job description.

switch-settings: Specify any combination of eight zeros
and ones that is used as the first switch
setting for jobs using this job description.


DEVRCYACN
Specifies the recovery action to take for the job when an
input/output error is encountered on the *REQUESTER device
for interactive jobs that use this job description.

Note: This attribute is ignored for non-interactive jobs.

*SYSVAL: The system value, QDEVRCYACN, is used as the device recovery 
         action for this job description. 

*MSG: The application program requesting the input/output operation 
      receives an error message that indicates the input/output  
      operation has failed. 

*DSCMSG: The job is automatically disconnected. After the job 
         is reconnected, it receives an error message indicating 
         that an input/output error has occurred, and that the 
         device has been recovered. Even though the device has 
         been recovered, the contents of the screen prior to the 
         error must be redisplayed. 

*DSCENDRQS: The job is automatically disconnected. After the 
            job is reconnected, the ENDRQS command is issued 
            specifying the processor that made the previous request. 
            If no request processor is available, the ENDRQS command 
            fails, and the message issued during the DSCMSG case is 
            signaled. 

*ENDJOB: The job is ended with the *IMMED option. 
         A job log is produced for the job. 

*ENDJOBNOLIST: The job is ended with the *IMMED option. 
               No job log is produced for the job.

TSEPOOL

Specifies whether interactive jobs are moved to another main
storage pool when they reach the end of the time slice.

*SYSVAL: The value in QTSEPOOL (system value) at the time 
         the job is started is used as the time slice end pool 
         action for this job description. 

*NONE: The job is not moved when the end of the time slice  
       is reached. 

*BASE: The job is moved to the base pool when the end of 
       the time slice is reached.

AUT

Specifies the authority given to users who do not have specific
authority to the job description, who are not on an authorization
list, and whose user group has no specific authority to the job
description. More information on this parameter is in commonly
used parameters.

*LIBCRTAUT: The public authority for the job description 
            is taken from the value on the CRTAUT parameter 
            of the target library (the library that is to contain 
            the job description). The public authority is determined 
            when the job description is created. If the CRTAUT value 
            for the library changes after the job description is created, 
            the new value does not affect any existing objects. 

*CHANGE: The user can perform all operations on the object except 
         those limited to the owner or controlled by object existence 
         authority and object management authority. The user can change 
         and perform basic functions on the object. Change authority 
         provides object operational authority and all data authority. 

*ALL: The user can perform all operations except those limited to the 
      owner or controlled by authorization list management authority. 
      The user can control the object's existence, specify the security 
      for the object, change the object, and perform basic functions 
      on the object. The user also can change ownership of the job 
      description. 

 *USE: The user can perform basic operations on the job description, 
       such as displaying its contents or using the job description 
       to start a job. The user cannot change the job description. 
       *USE authority provides object operational authority, read 
       authority, and execute authority. 

*EXCLUDE: The user cannot access the job description. 

authorization-list-name: Specify the name of the authorization list used.

TEXT

Specifies the text that briefly describes the job description.
More information on this parameter is in commonly used parameters.


*BLANK: Text is not specified.

'description': Specify no more than 50 characters of text,
enclosed in apostrophes.


JOBMSGQMX
Specifies the maximum size of the job message queue.

*SYSVAL: The value in QJOBMSGQMX (system value) at the time the
job is started is used as the maximum size of the job message queue.

maximum-size-of-job-message-queue: Specify a value in the range of
2 to 64 megabytes.


JOBMSGQFL

Specifies the action that should be taken when the job message
queue is full.

*SYSVAL: The value specified for the QJOBMSGQFL system value is used. 

*NOWRAP: The message queue does not wrap when it is full. 
         This action ends the job. 

*WRAP: The message queue wraps to the start of the message 
       queue when full and starts filling the message queue again. 

*PRTWRAP: The message queue wraps the job message queue when 
          full and prints the messages that are being overlaid 
          because of wrapping.

ALWMLTTHD

Specifies whether or not the job can run with multiple
user threads. This attribute does not prevent the operating
system from creating system threads in the job. This job attribute
is not allowed to be changed once a job starts. This attribute
applies to autostart jobs, prestart jobs, batch jobs submitted
from job schedule entries and jobs started using the Submit Job
(SBMJOB) and Batch Job (BCHJOB) commands. This attribute is
ignored when starting all other types of jobs. This attribute
should be set to *YES only in job descriptions used exclusively
with functions that create multiple user threads.


*NO: The job cannot run with multiple user threads.

*YES: The job can run with multiple user threads.

Examples for CRTJOBD

Example 1: Creating a Job Description for Interactive Jobs

CRTJOBD  JOBD(INT4)  USER(*RQD)
  RTGDTA(QCMDI)  INQMSGRPY(*SYSRPYL)
  TEXT('Interactive #4 job description
  for Department 127')

This command creates a job description named INT4 in the user's
current library. This job description is for interactive jobs
and is used by Department 127. When you sign on, you must type
your password. The characters QCMDI are used as routing data
that is compared with the routing table of the subsystem where
the job is run. All inquiry messages are compared to the entries
in the system reply list to determine whether a reply is issued
automatically.


Example 2: Creating a Job Description for Jobs on a Specified Queue

CRTJOBD  JOBD(BATCH3)  USER(*RQD)
  JOBQ(NIGHTQ)  JOBPTY(4)  OUTPTY(4)
  ACGCDE(NIGHTQ012345)
  RTGDTA(QCMDB)  TEXT('Batch #3 job
  description for high pty night work')

This command creates a job description named BATCH3 in the user's current
library. The jobs using this description are placed on the job queue NIGHTQ.
The priority for jobs using this description and their spooled output is 4.
QCMDB is the routing data that is compared with entries in the routing table
of the subsystem where the job runs. The accounting code of NIGHTQ012345
is used when recording accounting statistics for jobs that use this job
description.

Example 3: Specifying Request Data

CRTJOBD  JOBD(PAYWK)  USER(QPGMR)   RTGDTA(QCMDB)
  RQSDTA('CALL PAY025 PARM(WEEKLY UNION)')

This command creates a job description named PAYWK in the user's current
library. Jobs using this job description run under the IBM-supplied user
profile for the programmer, QPGMR, and use the accounting code found in
that user profile. If the job is started via the SBMJOB command, the
accounting code of the person submitting the command is automatically
used. The routing data QCMDB is compared with entries in the routing
table of the subsystem where the job is run. The request data passed to
the command processing program is a CALL command that names the
application program that is run and passes a parameter to it.
