Dear John,

I was also getting same error while starting up the SAP after SAP Kernel Upgrade.

Solution provided by you worked for me.

Thanks & Regards,

Lot of times plain old clean start helps.

Stop SAP (and Oracle). Reboot the server if you can; otherwise, clean the IPC using 'cleanipc <System_Number> remove'. Run it as root if you can, else as <sid>adm. Optionally, stop saposcol (saposcol -k) and Oracle listener before cleanipc so that everything starts clean in memory. You can do a 'showipc <system_number>' to see if any IPC objects still out there.

If it still doesn't start, the log files under work directory is a good place to look.

Hi,

DpMonInit failed - possibly no dispatcher running

Please post the "dev_w0" log from the work directory...

Also do "R3trans -d" and paste the content of "trans.log"

Sunil,

Do a stopsap r3. And then cleanipc, after that try to start the system. Check the log files in the work directory.

Hope this helps.

Thanks,
