DB2 JDBC Error. CLI0601E

Question

Hallo,
I am writing a jdbc application for Read / Write operation in Java. Here i implement several threads which perform Write+Read operations.
Within each thread, there is a method called dbprocessing().
which inturn calls DB2Write methods and then call DB2Read methods.
Here i share a single connection between Write and Read Object., and i make sure they are closed at the end of the transaction.
I receive this error for 1 or 2 threads out of 10 ,
Error:[IBM][JDBC Driver] CLI0601E Invalid statement handle or statement is closed. SQLSTATE=S1000
Questions:
1) i tried checking the connection obj, but its not null. can it be with Result set or with Statement/PreparedStatement.
2) any suggestions for jdbc - db2 driver.
Ref Configuration:
1) IBM DB2 v 8 and FP (CSD 6.0)
2) JDBC Driver - (java driver db2java.zip).

Answer 1

Hi,
i did solve this problem on my own.
i made a mistake in declaring the connection object as static. and hence since all the threads have the same.
and i could then have one connection per thread, declaring them as not static.

To have a better performance / better resource usage- we can share the statement object for multiple use of same SQL statements.
