hi,
i have a job which runs at around 8PM. problem here is there is a current date getting step. and based on current date am extracting some data.
so i should make sure your JOB always runs before midnight(because if it runs after midnit the date will change and it will extract next days data which is wrong).is there any way we can find out whether the job runs after or before midnit?

is there any CA7 SET UP? or any jcl step from which we can determine?

regds,
useit

How is current date fetched? Is your job running already in production?

I'm confused - what kind of solution are you looking for? Are you, by any chance, talking about Time Triggered Jobs in CA7?

Why don't you use a Business Date/Data Date, instead of current date, then you don't have to worry about Midnight, or re-runs.

hi,
its an existing job .inside there is a step to extract all the current days data . (current date is fetched using (DATE1).it usuall runs between 8-8.30 .

say if todays job got abended for some reason and we restarted it after 12.
the date1 wil be tomorrows date whic is actually incorrect. i want to empty out the extracted file in case if todays job runs after 12.

is there any way which we can find out and empty out the file in case if job runs after 12?? either through jcl step or ca7 set up?

regds,

Have a job - possibl;y your job - have a step that gets the date and stores it. The step that needs it can then read it either right there and then or after a restart. This assumes that you have restart control. If not, then make the date-getting step a prior job.

One possible solution is that, which probaly must be in use already, in RESTART instruction you mention about the specific use of date.

2nd, possibly, you can make use of EZACFSM1 and use the information from it in your favor:
Code:
//SYMBOLS EXEC PGM=EZACFSM1   
//SYSOUT    DD  SYSOUT=*       
//SYSIN     DD  *             
CCYY/MM/DD '&YR4./&LMON./&LDAY'
HH:MM:SS   '&HR.:&MIN.:&SEC'

Hello,

Another possibility is to have the code check the time and if the time is between midnight and some time (i.e. 9am) calculate the data as yesterday, not today. . .

This would only work as long as the job is always run in the evening.

My preference would be to put the data in a file and use this to control the run.

anju,

tested the jcl it ran fine. but am getting one hour difference in the time. what is the reason for this?

in JES2 JOB LOG -THE JOB START TIME AND END TIME IS "06.59.58"

BUT MY OUTPUT IS AS BELOW

Code:
********************************* TOP OF DATA **********************************
CCYY/MM/DD '2012/05/29' HH:MM:SS   '05:59:58'                                   
******************************** BOTTOM OF DATA ********************************


Is there any specific reason for this?

Regds,

I think the job produces UTC time and your system time is UK time.
UK time is 1 hour ahead of UTC time, So this maybe the difference?

Difference between GMT and BST.
publib.boulder.ibm.com/infocenter/zos/v1r12/index.jsp?topic=%2Fcom.ibm.zos.r12.halz002%2Fhead6.htm
this link says that the job produces UTC times

No that's not related to Day-Light savings.

When "&HR" is used with EZACFSM1, symbol translator utility, hour of the day is calculated based on UTC. And it'll be shown in two decimal digits, 00-23. Same is applicable to minutes and seconds part of the time.

Use the below symbols for the local time:
Code:
//SYMBOLS EXEC PGM=EZACFSM1   
//SYSOUT    DD  SYSOUT=*       
//SYSIN     DD  *             
CCYY/MM/DD '&YR4./&LMON./&LDAY'
HH:MM:SS   '&LHR.:&LMIN.:&LSEC'
