DSSendMail only upon the records reject

[dsedi]

Hi All,

We need to send a mail from the particular JOb if there is any reject records.we have designed like collecting allthe reject records into a sequential file then attaching that file to mail using a after Job subroutine.

The situation is we need to send the mail only if there is any reject records-if there is no rejects then do nothing.

experts- any best approch to accomplish this..

Thanks in advance.

modify the shel script, so that it will send the email only if the reject file has any records. May be you can do a count lines (wc -l) to count the number of lines in the file, and if the number of lines is more than 1 (assuming that the first line is column names) then send email else ignor it.

let me know if you need further help.

Hi,

For the same design, I have developed a routine, which will take the rejected file name and path as arguments.

Then I am checking the record count (wc -l) and if the record count is greater than 1, then I am sending a mail to the user.

Consider, First line in rejected file is column header.

Routine Code:

$IFNDEF JOBCONTROL.H
$INCLUDE DSINCLUDE JOBCONTROL.H
$ENDIF

call DSLogInfo("Routine starting",GetStoreUserStatusValue)
LinkCountUnix = 0
command = "wc -l " :FilePath :FileName
call DSExecute("UNIX",command,LinkCountUnix,ExitStatus)
LinkCountUnix = Field (LinkCountUnix,"/",1,1)
call DSLogInfo("Link Count For " :FileName " is " :LinkCountUnix ,GetStoreUserStatusValue)
If LinkCountUnix = 1
Then
Ans = 0
End
Else
Ans = 1
End

After a job processing, I am calling this routine.

Thanks
Bob

I wrote a script like this

Code: Select all

#!/bin/sh

ATTFILE=$1	# File to be attached and generally requiring encoding
SUBJECT="Error File attachment"	# subject liine
MAILTO=myname@mycompany.com
# Count the number of lines in the file
# The file is sent to wc using cat and a pipe
# because if you say "wc -l $1", you'll get
# the filename in the output also.

numLines=`cat $1 | wc -l`

# Test the number of lines counted
# and issue the desired output

if [ $numLines -gt 1 ]
then

echo "Error File having Data...Sending Email"
uuencode $ATTFILE | mail -s "$SUBJECT" $MAILTO
else
echo "No Data on File"
echo $numLines
cat $1

fi

But I dont see the attachment on output Email .....the process just stops after "Error File having Data...Sending Email" and when i say CTRL C on Unix prompt, it said

Code: Select all

(Interrupt -- one more to kill letter)
Null message body; hope that's ok

and I got a Empty Email with NO attachment.

Please let me know if I am doing something wrong here.

Thanks

Bob Thanks very much.

I assumed that u have created a Transform Functions which will take more then one argument(Not before/after subroutine) ..(coz...you have FilePath and FileName in arguement)

and also

Code: Select all

Then 
Ans = 0 
End

Instead of Ans = 0 we have to use the DSSentmail Routine...is that correct?

Thanks.

Hi

I tried to use the "DSSentmail Routine", but I guess I am missing some header file to include. And I am not sure which file to add in the routine.

I was checking each file in a loop and if the return code is "1" then I was sending a mail using notification activity.

Thanks
Bob

Hi

Can you try / test the same routine without "DSSentmail Routine"?

I was also facing the error with "DSSentmail Routine" in my routine

Thanks
Bob

I normally do this in the sequence job using an exec command utility.

Command
! test -s
Parameter
#$DATA_DIR#/outbound/#USVAR_SETUPPARMS.REJECTFILE#

I use the return value <> 0 to control the link to my Notification Activity.

But if you were going to use a routine, I would use the utilities to get the count from the link that writes to the reject file and not a unix utility.

[mikegohl]

Here is an example of getting the row count without calling a UNIX command:

ACCTREJcount = DSGetLinkInfo( JobHandle, "LKP_Acct", "LINKAcctRejects", DSJ.LINKROWCOUNT )

Hi Mike & All,

My design is like this. I have a job performing the lookup and writing the records into a sequential file through the lookup reject link.
I want to sent out an Email only If there is any records exist in the sequential file.

Until now,
I have tried writing a UNIX script to check the line count of the file and call the UNIX mailx functionality

i created a transform function as directed by Bob and used that in a routine activity

NOW, to try your approach, I should have a sequence job. Which contains a job activity (for the job) and then exec command activity.
But what should I have in

#$DATA_DIR#/outbound/#USVAR_SETUPPARMS.REJECTFILE#

I assume DATA_DIR is the parameter for Sequential file which is having reject records...
I am sorry I am not able to get #USVAR_SETUPPARMS.REJECTFILE#

Is this the complete PATH for the Sequential file?

Could you elaborate little more on this for the above said design?

Thanks very much.

[mikegohl]

Sorry for the confusion. The parameter is just the path/filename. I'm using a combination of ENV Variables and User Variable Activity to set the path and name.

[mikegohl]

I want a return code of zero when there are no rejects, that is why I use the ! operator. I turn off the "Automatically handle job runs that fail" and control the graceful exit of the program myself.

If you don't want to deal with the non zero return code, then use the wc -l command in the execute command activity. It will have a return code of 0 for both empty file and file containing records. You would then need a custom (conditional) expression something like this Field(trim( Execute_Command_5.$CommandOutput) ,' ',1) .

..... I turn off the "Automatically handle job runs that fail" and control the graceful exit of the program myself.

There you go... That is the Point..I got it...Thanks Mike....Now...It goes well for both the situation.(Data/No data)

Just getting a warning below if there is any data... (I am using ! and <> for control the notification)

Code: Select all

send_mail1..JobControl (@Execute_Command_4): Command ! test -s did not finish OK, reply = '1'

Any advice for this? Thanks in advance.

ACCTREJcount = DSGetLinkInfo( JobHandle, "LKP_Acct", "LINKAcctRejects", DSJ.LINKROWCOUNT )

Mike,

We are trying to test the scenario with your above suggestion.In the Job sequence, inside the Job activity trigger I have this below code in Custom(Conditional) Expression

Code: Select all

DSGetLinkInfo( Job_Activity_10.$JobName, "Lookup_70", "DsLink93", DSJ.LINKROWCOUNT )

Now, Its not controlling the Notification as we have expected.

From the DSGetLinkInfo help, i Read

Provides a method of obtaining information about a link on an active stage, which can be used generally as well as for job control. This routine may reference either a controlled job or the current job, depending on the value of JobHandle.

Question:

Can I use the DSGetLinkInfo in the Job activity Trigger expression? Or it should be used something like form "Jobbcontrol" ?

Thanks again for your inputs. It was really helpful.
