Permission denied:Sybase.sh

Hi all,

I have installed sap nw 7.4 on suse Linux with sap Sybase Ase 16. The installation was successful... No errors...

The Sap and Sybase SID is MK1. When I tried to set the environment variable by running Sybase.sh from sybmk1 user I am getting permission denied.

Please help me fix the error. Thanks in advance
