Maximum open cursors exceeded problem

Question

hi,
I am connecting to Oracle 8i (8.1.6 ) using JDBC2.0. I have a
block of code which does the following:
Open connection to database, create a Statement object say stat
and a Prepared Statement object say pStat
pStat.execute()
while(condition)
stat.executeUpdate(string);
pStat.close();
stat.close()
Close connection
Multiple execution of the block gives ORA-01000 error. I use
select user_name, count(*) num from sys.v_$open_cursor group by
user_name;
to check for open cursors and find that no open cursors result
from block. The maximum # of open cursors is set to 100.
Please help!
Regards,
Pratibha

Answer 1

If that were true, then connection pooling would never work. I
think the problem is:
while(condition){
stat.executeUpdate(string);
Oracle is creating a new process (cursor) for each call to
executeUpdate, which is never being released throught the whole
looping process. What would be better is:
while(condition){
stat = conn.createStatement();
int result = stat.executeUpdate(string);
stat.close();
conn.commit();
You have to destroy the connection, not just close it.
