Hi Deepak,
I have seen relevant sap note.do you help me how i can see cache memory??
because my other SID sybase GUI is not opening due to The variable $SYBROOT is not set to a valid directory whicch is on same zone(system).
Is this matter if environmental variable not set even though my xclock is working??

Aziz.
