need to Run csscan in Background ?

Folks

Need to Run csscan Utility as Background processes because the LAN Network Connecting my PC to the SUN DB Server is somewhat Unstable. Can csscan be Run as a Background Unix Process or NOT?

NOTE - csscan is Running in the foreground ($ csscan FULL=Y FROMCHAR=US7ASCII TOCHAR=AL32UTF8 ARRAY=10240000 LOG=chrchk CAPTURE=Y PROCESS=32). Since my Database is 3 TB, the process usually Fails before completion due to LAN Network Problems.

To my understanding csscan needs to be Run as "/ as sysdba" only

Config

Solaris 10

Oracle RAC 10gR2

Following Attempts Failing with Errors:-

$ csscan FULL=Y FROMCHAR=US7ASCII TOCHAR=AL32UTF8 ARRAY=10240000
