The Check Job Message Wait command allows you to send a notification
when a job is waiting for a response to an inquiry message (MSGW
status). The notification can be one or more of 1) Send a break
message to a message queue on the current system, 2) Send a break
message to a workstation on a different system (using FTP), 3) Send
an Email to a user (using TAA tool SNDTXTMAIL)
A typical command would be:
CHKJOBMSGW SBS(xxx) WAKEUP(600) MSGQ(*YES)
A never ending job would be submitted to the QSYSNOMAX job queue with
the name CHKJOBMSGW. You may also specify a jobq in the JOBQ
parameter. It would wakeup every 600 seconds (10 minutes) and check
the status of jobs in the named subsystem (or all subsystems). By
default, only batch jobs are checked. If a job was in a MSGW status,
a break message would be sent to the message queue named in the
The REPEAT parameter determines how often the message will be resent.
If the same job is still in a MSGW status (with the same function
value as seen by WRKACTJOB) after the CHKJOBMSGW job wakes up at the
next WAKEUP interval, the time of the last notification plus the
REPEAT time is compared to the current time. If the REPEAT time is
greater than the time of the last notification, another notification
is sent. Thus the REPEAT parameter allows you to control excessive
notification. The default is 1800 seconds or 30 minutes.
By default, the break message will be sent as soon as the wakeup
interval occurs and a job is in the MSGW status. This could happen
within a few seconds of the job entering the MSGW status. An option
exists with the SKP1STNDF parameter to skip the sending of the first
notification. This may allow normal system operations to respond to
the message and prevent any notification.
Multiple CHKJOBMSGW jobs may be active for unique subsystems. For
example, you could have a different notification type depending on
the subsystem where the job was running. that may be sent.
The following describes the types of notifications in more detail.
You may specify one or more of the types.
You may send a break message to a workstation on another system if
you have an FTP connection. The FTP2 TAA Tool command is used to
send the notification which is a SNDBRKMSG command.
The remote system must have an i5/OS operating system and the current
user must have a profile of the same name on the other system.
When FTP is used, a password must be sent for the user. If the
source for a CHKJOBMSGW command is placed in a source file, the
password would be viewable by all users authorized to the file. To
prevent this exposure, the RTVMSKPWD tool is used. This allows up to
99 passwords for a specific user to be stored in a masked manner in a
file in TAASECURE. When using CHKJOBMSGW, the MSKPWDNBR parameter
must identify which masked password should be used. See the
discussion with RTVMSKPWD.
You may send an E-Mail to another system. This is done via the TAA
Tool SNDTXTMAIL. You must have a proper configuration to use
SNDTXTMAIL. You must have a entry in a MAILADRP file for the
identified user which is used to determine the E-Mail address. See
the discussion with the MAILADR tool.
Break message notification to a user on the current system
You may send a break message to a workstation on the current system.
The SNDBRKMSG command is used.
The ENDJOBMSGW command is also supported and allows the job to end
normally. The command will request the specified job to end with a
delay time of 150 seconds.
The ENDJOBMSGW job wakes up every 2 minutes (or less if the WAKEUP
time is less than 2 minutes) and checks to see if a controlled cancel
is set. If so it ends the job normally.
CHKJOBMSGW escape messages you can monitor for
None. Escape messages from based on functions will be re-sent.
ENDJOBMSGW escape messages you can monitor for
None. Escape messages from based on functions will be re-sent.
CHKJOBMSGW Command parameters *CMD
SBS The name of the subsystem to be checked. A
qualified library name may be entered. The default
is *LIBL. Only the jobs in the specified subsystem
are considered and the subsystem must be active.
WAKEUP The wakeup interval for the batch job. The default
is 600 seconds (10 minutes).
At the end of the wakeup period, the jobs in the
named subsystem(s) are checked for a status of MSGW
The text of the notification is the same regardless
of which notification type is used (one or more of
MSGQ, FTP, or EMAIL parameters must be *YES).
The notification would appear as follows:
The CHKJOBMSGW command has found job
xxx/yyy/zzz with a status of MSGW on system
xxx on mm/dd at hh:mm AM (or PM).
EMAIL A *YES/*NO parameter for whether E-Mail will be
used. *NO is the default.
If *YES is specified, the EMAILUSR parameter must
describe the user name to send Email to. The name
must be specified in the MAILADRP file (see the
MAILADRLIB parameter) and a valid mail configuration
must exist. See the discussion with the MAILADR
tool. The TAA Tool SNDTXTMAIL is used to send the
FTP A *YES/*NO parameter for whether FTP will be used.
*NO is the default.
If *YES is specified, the TAA FTP2 command is used.
The remote system must have an i5/OS Operating
System and the current user must have a profile of
the same name on the remote system. A SNDBRKMSG
command will be sent if notification is needed. You
must fill in the parameter for RMTSYS.
FTP requires that a password be sent for the remote
user. Since it is expected that you will place the
CHKJOBMSGW command in a form where it can be re-run
without re-entering all the parameters (such as
using a job schedule entry or a CL program), it is
not desirable to have a password which can be
Instead of requiring a password, the FTP option
requires that the TAA RTVMSKPWD tool be used for the
MSKPWDNBR parameter. You should review what is
required for this tool by using DSPTAA RTVMSKPWD.
The user of CHKJOBMSGW must have a masked password
by entering the CHGMSKPWD command.
The MSKPWDNBR parameter defaults to 1. An error
will occur if there is no masked password for the
MSKPWDNBR of the current user.
If the workstation on the remote system is not
signed on, no error occurs. The message will remain
in the message queue.
MSGQ A *YES/*NO parameter for whether a message queue on
the current system will be sent a break message.
*NO is the default.
If *YES is specified, a message queue must be named
in the BRKMSGQ parameter.
If the workstation is not signed on, no error
occurs. The message will remain in the message
REPEAT The number of seconds to delay before an additional
notification is sent for the same condition. The
default is 1800 seconds (30 minutes). Using the
default, a notification will only occur at a maximum
of once every 30 minutes. Because of the time delay
in the WAKEUP parameter and the time to run
CVTWRKACT, the time delay will probably be somewhat
SKP1STNDF A *YES/*NO parameter for whether to skip the first
*NO is the default meaning the first notification
will occur as soon as a wakeup interval is reached
and a job is recognized as in a MSGW status. This
could be a matter of seconds depending on the timing
of when the job enters the MSGW status and when the
next wakeup point occurs.
*YES may be specified to skip the first
notification. This may allow normal system
operations to answer the message and prevent a
notification. If *YES is specified, the REPEAT
parameter determines when the first notification
JOBTYPE The job type to convert. B is the default and means
only batch jobs. B = Batch includes job types of
BCH, BCI, PJ, and other batch types as seen on
WRKACTJOB. The other supported values are *=ALL,
A=Autostart, I=Interactive, M=Monitor, R=Spool
reader, S=System job, X=Start CPF, and W=Spool
JOB The job name to be used for the submitted job. The
default is CHKJOBMSGW. Two jobs of the same name
may not be active.
By entering a subsystem name for the SBS parameter
and a unique job name you may have different
notifications sent depending on the subsystem.
EMAILUSR The name of the E mail user to send a notification
to if EMAIL(*YES) is specified. The name must exist
in the MAILADRP file as specified for the MAILADRLIB
parameter. See the discussion with the MAILADR
MAILADRLIB The name of the library where the MAILADRP file
exists. *LIBL is the default. See the discussion
with the MAILADR tool.
RMTSYS The remote system name to be used if FTP(*YES) is
specified. A valid FTP configuration must exist.
MSKPWDNBR The RTVMSKPWD tool is used by FTP(*YES) to prevent
having a source member with an actual password
included. A single user may have up to 99 passwords
for different systems. The number represents which
masked password will be used. See the RTVMSKPWD for
how to enter a masked password.
BRKMSGQ The workstation message queue to send a break
message to if MSGQ(*YES) is specified.
JOBQ The name of the job queue where the job will be
submitted. It defaults to QSYS/QSYSNOMAX.
ENDJOBMSGW Command parameters *CMD
JOB The name of the job that was submitted by CHKJOBMSGW
that will be ended. CHKJOBMSGW is the default. A
DELAY time of 150 seconds (2 1/2 minutes) is used.
The specified job will end normally within this
