What are the sizes of the sga's of the oracle instances running on the box. How many user processes on Oracle and SAP does ur box handle.
The server will have to be tuned based on these parameters using vmtune to reduce double buffering phenomenon especially while using oracle.
I had the same...

If your tar backup is an absolute path backup and you want to restore the files from the backup in another dir then you will have to use the command pax.
Lets say that you have backed up /home using absolute path backup

For Eg
#tprof -x sleep 30
This cmd specifies to run the trace for 30 secs
