How to batch load data to several tables

Question

Hi,
One customer have such data structure and have large number of data(arround 10 Million). I think it's proper to convert them to data that SQL loader can recognize and then insert into Oracle 8 or 9. The question is how to convert?
Or maybe to insert them one by one is simpler?
1:     Component of Data
The data file consists of nameplate and some records.
1.1 Structure of nameplate
ID     datatype      length(byte)     comments
1     char     4     
2     char      19     
3     char      2     
4     char      6     records in this file
5     char     8     
1.2 structure of each record
ID     datatype     length(byte)
1     char     21
2     char     18
3     char     30
4     char      1
5     char 8
6     char      2
7     char      6
8     char      70
9     char      30
10     char      8
11     char      8
12     char      1
13     char      1
14     char      1
15     char      30
16     char      20
17     char      6
18     char      70
19     char      5
24     bin（blob）     1024
25     bin(blob)     defined in ID19
2: data file and table spaces in database
dataID 1-13 of each record insert to table1,
14-18 to table2, and 19,24,25 to table3
Is there a method to convert them to some data that SQL loader can input and then at a whole load into Oracle 8 or 9?
Thanks &Regards.

Answer 1

I've check the Oracle Utilities docs, but did not find a way to load so many data files at a batch action.
In my view the solution consist in two ways:
1, Load each of them individualy individually to different tables by some programme. But the speed may be problem because the uninterrupted db connections and close.
2, Convert them to one or three files then use SQL loader.
But either isn't much easy, I wonder if there's a better method to handle.
Many thanks!
