its giving error as @ is not defined others also scripts file,i want to run these scripts file while running applicationtables.sql ..anybody please replay to me urgent.

It seems you are trying to run "scripts" within a script file - probably trying out the Oracle SQL*Plus approach. This does not work in DB2's command line processor.

Would recommend creating a shell script or Windows batch file that has the following formats -
db2 connect to <dbname> user <username> using <password>
db2 -tvf file1.sql
db2 -tvf file2.sql
