Background jobs running with no logs

[Former Member]

Hi Experts,

There are 3 background jobs in the system and all the 3 background jobs are running in SM50. But there is no logs for the same in SM37 and SM21. When I try to kill it in SM50, it is not getting killed and when I try kill from OS level, it starts again with a different PID.

Not able to understand this behavior of the system.

SM50 screenhot:

Kindly help in resolving the same.

Thanks,

Hello Harikrishna,kill -USR2 <PID>

you can try to send the signal (note 112):

kill -USR2 <PID>    (unix)

or

sapntkill.exe -USR2 <PID>     (windows)

to the work processes to create a call stack in dev_w* trace, so that you can see in call stack, at which function it is hanging.

SM50 : Select the work process - click on display file i.e. Ctrl+shift+F8,
come to end of page, see if any logs is getting updated,

2) double click on each Work process and enter inside in database part - check Direct read and sequential read any thing getting changed.

you will get an idea weather at database any activity is going on or not.

3) If you want to cancel -> then select the work process -> Administration -> process -> cancel -> without core.

Hello Harikrishna,

Have you checked sm21 logs .There must be some info there.

Are your regular house keeping jobs running fine?

Please check your file system usage i.e. /sapmnt/<SID>/global

There can be a possibility that file system is filled up and no more logs could be generated.

Thanks

Hi, Divyanshu,

There are no logs for the same, check the status of these jobs, they are running.

Hi,

Check the BGD job status in SM37 , by giving Old Dates, if any jobs are running under released condition and got delayed ..

Hi Hari,

Do you have any application server apart from which you have logged in.

Check the full process details from SM66 about how many dialog and background processes are running.

Hi,

There are no logs for these 3 background jobs. In SM66 it shows running.

No logs in SM37 and SM50, it only shows that it is 'running' check the screen shot that I have attached. Also, SM21 and ST22 shows nothing.

Also, i have check the date from since 1 year, it says no jobs found.

Hi Hari,

Can you take a full system reboot and check the results. There could be some hanged processes running.

I have tried to cancel and also kill from OS level. But they start again with a new PID.

Hi Hari,

If this is the case, then please take a full system reboot.

Can you check for processes from OS level. Like tp , process with parent PID of these processes.

Also, try DPmon to kill these processes.

I have killed these 3 processes from dpmon but they start again with a new PID.

[divyanshu_srivastava3]

I think you application server has only 3 BG processes, please increase number of background processes by 2 and share the results.

Divyanshu
