RE: File Lock Problem

Thanks Vijay/Madhavan. Your solution works.

One problem still exists. I make one connection for the entire application
by globally declaring the Connection variable. So I can close it at
application exit point. What happens is that if a database file is accessed
for  insert/update, wrkobjlck shows the following -


 Opt   Job          User         Lock      Status          Scope     Thread
       QZDASOINIT   QUSER        *SHRRD     HELD           *JOB


Even if I close all the prepare and resultsets, still this remains. Of
course unlike the earlier state, it does not keep on increasing. My thinking
is that, when the first time a prepare statement is executed the database
manager creates a pointer to the table which is attached to the connection
pointer. All prepare statements and resultsets created subsequently are
attached to this table pointer. So when we close prepare statements and
resultsets all these pointers created gets closed, but the table pointer
remains open. Probably what I need is a way of closing this table pointer
keeping the connection pointer alive.

Please do correct me if my thinking is wrong.

Is there a way of removing this file lock after the user exits from the
program? At the moment even after exiting from the program, the lock
remains.


Thanks

Cheers
Vijosh

check whether all the resources you used were released. It means you should
close statement, result set, and importantly connection objects. Each and
every system has some limitation in creation of connection objects and if
you use some application server like weblogic, you can explicitly fix the
number of connection objects. Ensure that the following code is present in
your program. Hope this will help you. Please drop your feedback.

Vijay.

finally{
try{
         if(con != null) con.close();
         if(statement != null) statement.close();
         if(resultset != null) resultset.close();
    }catch(SQLException sqle) {}
}
