Hi,

1) Download the latest Kernel from www.service.sap.com/swdc which corresponds to your OS & DB and transfer to your AIX system

2)uncar these new kernel files using SAPCAR(from AIX).

3) Stop SAP & DB.

4) Take a backup of existing kernel (backup /sapmnt/<sid>/exe)

5)copy the new kernel files to /sapmnt/<sid>/exe

6)Check the permissions of the copied files.

7)Start DB & SAP

8)Confirm the kernel release from System ->Status

Reward Points if it was helpfull.

Regards,

Sam
