Hi Prem,
the 2G limit should be solved since 8i dbms but in case you can use a named pipe to override this limit:

for DMPFILE in imp01.gz imp02.gz .....imp09.gz do

     mknod /tmp/orapipe p
     gunzip < /tmp/orapipe > ${DMPFILE} &
     imp user/pass file=/tmp/orapipe <options>
     rm -f /tmp/orapipe 

Regards,

Alessandro
