Not quite on topic, but why call your variables $var1 etc? Better would be to give them descriptive names. You can then dispense with the comments and don't have to refer elsewhere when they appear in the code. 

my $var1 = "dbname";                    #Database Name
my $var2 = "user";              #Username
my $var3 =  "pass";                 #Password
my $var4 =  "select directory_path, keyword1, keyword2, keyword3 from 
+load_instance where rule_id = 
+'1'";

becomes 
my $database = "dbname";
my $username = "user";
my $password = "pass";
my $query = 
  "select directory_path, keyword1, keyword2, keyword3 from load_insta
+nce where rule_id = '1'";
...
my $dbh = DBI->connect( "DBI:Oracle:", $database, $username, $password
+ );
...
$sth->prepare($query);
