sapstart process not running

[Former Member]

Hi all,

We were trying to stop SAP using stopsap command.But it failed saying that instance has already been stopped.

Enviroment linux red hat release 4 and oracle 10.0.2.0.5.

When checked we found out that the sapstart process is not running.Checked the work directory and there is no kill.sap file also.

Reboot would do the trick, but we wanted to know if there is a way to shutdown sap.Oracle has been shutdown using shutdown abort.

i tried using kill -2 <pid> but still the process are not getting killed.Thanks.

What processes can you see running under <sid>adm?.... kill -9 should remove them.

Along with Juan's Suggestion , I would Suggest you check for any Semaphores in the System and Kill them if they are not Required .

Ambarish,

Check for the processes which are running with user sidadm and kill them.

Also clear the ipcs so that all the processes related sidadm are killed.

Probably ipcs -a|grep sidadm should give the list of all the shared memory processes running with sidadm user.

Hi,

This is is linux removing semphores is not easy with IPCRM.Since they dont get released easily.I dont know why it happens in linux like that.

I cannot killl the process using kill -9 

Any error messages when trying to kill the processes?... in anycase if your DB is offline and your OS is not responding maybe you should consider a restart.

Hello,

normally a SAP system ist stopped by a kill -2 on the dispatcher (the parent of all work processes) which is done by sapstart or in sapstartsrv. If this does not work check the dispatcher trace or open a message on the SAP Market Place.

Please do not use kill -9. The SIGKILL closes the process directly. All open I/Os are kept open and also all child processes. A kill -6 (SIGABORT) should work as well.

Best regards,
