Oracle 10G AS, Batch Update doesn't commit.

Question

Hello,
We are using Batch uptdate to commit a set of records, but to our surprise one of the batches commits in DB and the other doesnt.
The below pseudo code explains our scenario :
String str1="INSERT INTO TBL1 (COL1,COL2) VALUES (?,?) ";
String str2="UPDATE TBL2 SET COL1=? WHERE COL2=?";
PreparedStatement pstmt1=conn.prepareStatement(str1);
PreparedStatement pstmt2=conn.prepareStatement(str2);
for(500 recs)
pstmt1.addbatch();
pstmt2.addbatch();
On 500 Recs
//This batch updates the DB and commits too
pstmt1.executeBatch();
pstmt1.clearBatch();
con.commit();
//The Batch executes successfully, but updates are not reflected in DB,
//which may mean that it must not be committing in DB
pstmt2.executeBatch();
pstmt2.clearBatch();
con.commit();
- In the above, pstmt1 is an INSERT and pstmt2 is an UPDATE.
- It so happens that at the end, DB reflects Inserts done by pstmt1, but it doesnt reflect the Updates of pstmt2.
- We have also fired a SELECT stmt immediately after pstmt2 Execute Batch, but the updated values are not reflected.
- Also the above scenario works absolutely fine if we use a STATEMENT instead of a PREPAREDSTATEMENT for pstmt2.
Set up Details:
App Server :: Oracle 10G AS for Linux 2.1,
Database Driver :: Oracle 10G Driver which is bundled with Oracle 10G AS
Database :: Oracle 9i
Any ideas in this regards would be highly appreciated.
Thanks !

I think this is not the right forum for this question; probably a JDBC forum or one of the Oracle AS forums.
