Here is my updated code

 sub ReadPolicies { # based on the below command it reads values in ar
+ray

my ($type) = @_;
my @Policies = `/opt/OV/bin/opctemplate -l | grep -i $type | awk '{pri
+nt \$2}'`;
return (@Policies);

}

#MAIN
My @FailoverPolicies = &ReadPolicies(DBSPI);

For (my $i=0; $i < @FailoverPolicies; $i++) {
my $cmd "/opt/OV/bin/opctemplate -e" . " " . "$FailoverPolicies[$i]";
my $output= `$cmd`; # here i expect this command read each value from 
+the array and take action, -e to enable

}

and this works fine but the problem i face is that i see so many <defunct> process on system and i think it is because first command is not completed and second also start and so one and one point this hangs.

Thank You.
