'number of open cursors exceeded' exception - 10.3.1

Hi All,
We have may DynamicSQL statements fired from our processes due to which we are getting 'number of open cursors exceeded' exception. We don't want to increase the limit of the maximum open cursors. Is there any way to close the cursors explicitly in 10.3.1?
I am aware that when the iterator fetches the last result the cursor gets closed (in the case of any select query) but we have faced the same issue once/twice in the insert query also, is it because we have fired one insert after the other immediately? How much time does a cursor takes to close (implicitly) in the case of insertion of data?
Thanks in advance..

Hi,
Please see my post: Re: Cursor closing using DynamicSQL.executeQuery
Hope this helps,

Urgent!!! ORA-01000: maximum open cursors exceeded

hello guys, I have done a search in this forum and read plenty of threads, but I didn't find any official answer to this question. In my code, I have closed all the statements and resultsets after using them, but I still got the MAXIMUM OPEN CURSOR exceed exception.
I am not sure whether I close the stmt and rs in the right way. Which one should I close first, the statement or the resultset? Does the order matters??? Thanks a million you can have a good way to solve this problem!!!
Statement st= null;
ResultSet rs = null;
try{
.......// some code
}catch(SQLException sqle){
finally{
if(st!=null)
st.close();
if(rs!=null)
rs.close();

The connection I am using is from a pool. I can't close the connection because I need to return it to the pool...
BTW, I just solved the ORA-01100 problem. Here is what I did, I hope it may be helpful.
The original code I have looks like this. That's the code that generates the ORA-01100 exception.
Connection conn = null;
PreparedStatement pstmt= null;
ResultSet rs = null;
try{
      conn = Pool.getConection(); // get connection from pool
      String sql = "someSQL";
      pstmt = conn.prepareStatement(sql);
      rs = pstmt.executeQuery();
      while(rs.next()) {
          // do something with the resultset
      // here, I reuse the pstmt and rs.
      // I think that is what cause the ORA-01000 problem
      // because I don't think there is anything wrong
      // with the finally block
      sql = "another query";
      pstmt = conn.prepareStatement(sql);
      rs = pstmt.executeQuery();
      while(rs.next()) {
          // do something with the resultset
}catch(SQLException sqle) {
        // ignore.......
} finally {
   try
      if(rs!=null) rs.close();
      if(pstmt!=null) pstmt.close();
      if(conn != null) Pool.returnConnection(conn); // return connection to pool
   } catch(Exception fe) {
}Here is the fixed version of the code that eliminates the ORA-01000 error in my case. If in your code, you re-use your statements, preparedstatments or results, You can try it too.
Connection conn = null;
PreparedStatement pstmt= null;
ResultSet rs = null;
try{
      conn = Pool.getConection();
      String sql = "someSQL";
      pstmt = conn.prepareStatement(sql);
      rs = pstmt.executeQuery();
      while(rs.next()) {
          // do something with the resultset
      // In the fixed version, I only added the block of
      // code below and it solves the problem.
       // Before I re-use the preparedstatments,
      // statement, and result for a new query,
      // I closed them and set them to null.
     try {
        if(rs != null) rs.close();
        if(pstmt != null) pstmt.close();
        rs = null;
        pstmt = null;
     } catch(Exception ie) {
       // ignore
      sql = "another query";
      pstmt = conn.prepareStatement(sql);
      rs = pstmt.executeQuery();
      while(rs.next()) {
          // do something with the resultset
}catch(SQLException sqle) {
        // ignore.......
} finally {
   try
      if(rs!=null) rs.close();
      if(pstmt!=null) pstmt.close();
      if(conn != null) Pool.returnConnection(conn); // return connection to pool
   } catch(Exception fe) {

Sql exception : maximum open cursors exceeded

I run applicatio to insert data into the table, and update data into the table, when it processes more than 800 record, it throws the sql exception :maximum open cursors exceeded.
Who knows the reason?
Thanks.

I have a similar problem where in I close the Result set, Statement and close the connection in a finally block. Even though, the connection.close() executes sucessfully, with no exceptions being thrown, I still see the connection opened in ORacle. This builds up connections for our application and by the end of the day we are up with about 500 connections open and rising.
After closing the connection, I did check the value for connection.isClosed() and it still says false (like before the connection was closed). Since we are using a custom Connection manager to pool the connections, my interpretation is that even after the connection is closed, it doesn't get released. I have tried setting the connection to Null, used the finalize method to still check for connection != null and do one more close(), but still the connection is still open.
Am I mistaken in my thinking that even though the connection seems to be closed(), it doesn't get released until the GC runs and picks it for disposal? For every job, after the process is completed we have about 7 open connections and at times the number stays at 7 for some more jobs (Web application driven by servlets and some rmi in the background process). I thne see a surge in the connection after some more jobs are processed and so am not sure whether its the connection manager to blame. Could any one have any pointers on this issue.
Thanks for your response.

The code below is deleting fine. Check your $id is valid. I wonder if ADOdb has some quirks with binding and variable creation/destruction, similar to #1 in http://www.oracle.com/technology/tech/php/htdocs/php_troubleshooting_faq.html#bindvars
<?php
See ADOdb Tutorial for Oracle: http://phplens.com/lens/adodb/docs-oracle.htm
drop table mytab;
create table mytab (city varchar2(20), country_id varchar2(20));
insert into mytab values ('SF', 'US');
insert into mytab values ('Sydney', 'AU');
insert into mytab values ('London', 'UK');
commit;
require_once("/home/cjones/public_html/php/adodb5/adodb.inc.php");
$db = ADONewConnection("oci8");
$db->Connect("//localhost/XE", "hr", "hrpwd");
echo "Before:\n";
$rs = $db->Execute("select city from mytab");
while ($arr = $rs->FetchRow()) {
 echo $arr['CITY'] . "\n";
$s = $db->Prepare("delete from mytab where country_id = :ci");
$db->Parameter($s, $ci, 'ci');
foreach (array('US', 'AU') as $ci) {
 $db->Execute($s);
echo "After:\n";
$rs = $db->Execute("select city from mytab");
while ($arr = $rs->FetchRow()) {
 echo $arr['CITY'] . "\n";
?>There's another sample in the ADOdb OCI8 driver:
 Usage:
 $stmt = $DB->Prepare("insert into table (col0, col1, col2) values (:0, :1, :2)");
 $DB->Bind($stmt, $p1);
 $DB->Bind($stmt, $p2);
 $DB->Bind($stmt, $p3);
 for ($i = 0; $i < $max; $i++) {
 $p1 = ?; $p2 = ?; $p3 = ?;
 $DB->Execute($stmt);
 }For queries I know this works. I haven't seen any examples that prepare once.
$rs = $db->Execute("select city from mytab where country_id = :ci", array('ci' => 'UK'));
while ($arr = $rs->FetchRow()) {
 echo $arr['CITY'] . " \n";

Maximum Open cursor Exceeded error when deleting records from a table

I have a strange problem.
I have a table EMP_MASTER . Whenever I am trying to delete a record from this table, I am getting Maximum no. of open cursor exceeded error. But this error doesnot come when i delete from any other tables. And no. of open cursor is much lesser than OPEN_CURSOR parameter.
All other tables (around 700) has foreign key constraint to this EMP_MASTER table for created_user paramater.
Is it some thing like, when I am trying to delete a record from EMP_master, implicit cursor opens up and checks all referenced tables. and that limit gets exceeded ?
Please help.
Thanks,
Raj

Is there a limit on which no.of references made to a column ? Because one column in this field, Emp no is being referenced in almost every other table. around 700 tables. Will it have any adverse effect ?That should have nothing to do with your problem directly. Again, those tables could have triggers defined on them and you are leaking cursors in one of those triggers (wild guess).

Oracle and "Maximum open cursors exceeded"

Hi,
I am using Weblogic 7.0sp2 with Oracle 9.2.0. Since we are using manual JTA
transactions and the 9.2 drivers are buggy in that respect, we are using the
9.0.1 thin drivers delivered with weblogic.
The problem I have is that after a while, we get the now classic "Maximum open
cursors exceeded" error on connections from our connection pool (used through
a
TX datasource). I have of course checked all our JDBC code and it is fine. We
do not leave any statement/connection open. In fact, I am certain that the
problem is not caused by our applicative code.
The reason I am so positive is that the numbers of open (cached) cursors is
growing, even though there is no activity on our application (I mean no
activity at all). The number of cursors is regurlarly increasing by one
every 5 minutes until it reaches the maximum allowed for a session.
I have listed the statements corresponding to the opened cursors (they
do not belong to our code, as you might have guessed):
SELECT sysdate, user from dual
select longdbcs from javasnm$ where short = :1
select longname from javasnm$ where short = :1
As you can see, there are only three different statements. You can get
the statements from the system view v$open_cursor for a given session
but it will only give one row per different statement. If you want to know
the # of opened cursors in your cursor, use v$sesstat with statistic# = 3
(opened cursor current).
I suspect something is wrong in the connection testing done by weblogic
for the pool (I have activated test on reserved connections and test table
name is "dual") that leaves a resultset/statement behind. What is weird
though is that the refresh period is still 0 (not 5 minutes as you would
expect from the cursor growth rate...).
I would not say that it is an Oracle bug (as stated in some BEA FAQ I read)
since our application JDBC code does not exhibit the same problem. The
problem appeared with recent version of WebLogic for which the session
cursor cache is enabled, I suppose for performance reasons - this
is set by isssuing "ALTER SESSION SET SESSION_CACHED_CURSORS = ...".
Talking about this, does anybody know to which value WebLogic sets this
parameter when intializing the connection (this is neither
documented/configurable)?
Up to now, I have come up with possibly two workarounds, neither of which
is satisfying:
- resetting the pool from time to time
- issuing "ALTER SESSION SET SESSION_CACHED_CURSORS = 0" when I get a
connection from the pool. I have not tested this one personally (read
in a newsgroup that someone else did successfully) but it is supposed
to reset the cursor cache that is causing the trouble.
Any help will be greatly appreciated,
Regards,
Thierry.

Thierry.Hi. We don't make those queries either. I suspect they are internal to the
oracle driver. One thing you can try is to set the size of the pool's
statement cache to zero. Oracle will retain cursors for every statement we
cache. The alternative is also to tell the DBMS to allow a given session
more cursors.

Open cursors exceeded - common problem, different scenario

I searched both the web and the java forums and found the "maximum open cursors exceeded" to be a very common problem, one in which I have, but I can't seem to solve it and I was wondering if the way I am doing certain things are causing it.
Here is my program. I have a java server running that is acting as a midway between a java applet and an Oracle database. Since many users will most likely be using the applet, and since the applet has the ability to alter data in the database, I wanted to Synchronize my database connections.
So because of this, my server has a static class with all the database calls, including a connection call that connects to the database when it is first started up. Also, I return ResultSets to the server, but I never close either my ResultSet or my Statement. I do this because I only have one global of each of them. Otherwise I would have to close them from the server, and this worries me as far synchronization goes. Thus, with a global statement, I am just reinstantiating it every time. This may very well be my problem.
Should I?
1. Not have a single connection to the database but instead create a new connection every time a database call is made?
2. Do not make the resultset and statement global. (And if this is yes, how would I go about closing them after I return the result set to the server).
3. Leave the resultset and statement global but go ahead and try to close them from the server.
4. Or any combination of the above.
Thanks. I appreciate any help advance. This problem has been driving me insane the last couple of days. If it would help to post my database connections code then I will gladly do so.

Hmmm. I have worked on it all day and still have nothing. If anyone has even a shred of help, that would be greatl appreciated. I am going to just go ahead and post my code just in case that helps anyone.

How to get highest number of open cursors within the current calendar day

Hi all ,
i need to know how to get the highest number of open cursors within the current calendar day.
Thanks ,

823030 wrote:
the issue is my customer is getting the error ORA-01000: maximum open cursors exceeded and we need an sql statment that gets the following values :
-highest number of open cursors experienced in the current calendar day.
-current open cursors
-and maximum open cursorsThis error is rare. It happens when
a) the value of the open cursor parameter is set extremly low (default is something like 1000). Low would be something like 10.
b) <strike>you have many concurrent users(=sessions) and </strike>the application does not use bind values
In this case each select will open a new cursor, instead of reusing it.
c) you have a select that opens a cursor for each line. This can happen with a statement where you have the CURSOR keyword somewhere in the select or where clause. Those cursors will be closed when the select is finished. But during the run time of the select, all cursors stay open.
To track the number of "open cursors" during the day you would need to implement some monitoring. Maybe based on the view that was already mentioned.
Edited by: Sven W. on May 16, 2011 2:30 PM - since the parameter is on session level, other open cursors should not influence it much.

Maximum open cursors exceeded with Sybase TG

Hi,
Does anyone knows if we can use the HS_OPEN_CURSORS with Oracle transparent gateway for Sybase ?
I've got the error message :
ORA-01000: maximum open cursors exceeded
Thanks

This depends if the maximum number of cursors exceeded in the GTW or within the db.
In my eyes the OPEN_CURSORS of the db is normally the limiting factor.
HS_OPEN_CURSORS defines the maximum number of cursors that can be open on one connection to a non-Oracle system instance.
The value never exceeds the number of open cursors in the Oracle database server. Therefore, setting the same value as the OPEN_CURSORS initialization parameter in the Oracle database server is recommended.
So better check out the OPEN_CURSORS of the db and increase them.

You have better to select your data (select connection) and store them in an arraylist for example, then close the 'select connection' and finally
loop through the arraylist and make as much update as the list size.I disagree. Huge amounts of data could be being pulled from the database (that is one of their strength) and if the data can be processed one row at a time there is no reason to load it all into memory.
=> take a look [here |http://java.sun.com/docs/books/tutorial/jdbc/TOC.html]
and [here |http://java.sun.com/docs/books/tutorial/jdbc/basics/prepared.html] for preparedstatements
Ditto to PreparedStatement
OP. Is it possible that the Statement being returned (from what looks like JBoss) has the close method overwritten and does not actually return the resource (some type of pooling)?

Maximum open cursors exceeded prblm , code attached for review

     }The database is oracle 10g
The loop is going for 300 times with out any data and then comes down with this exception.
Experts please give your valuable help in this.

I had previously tried to close the statement
immediately after the exceute statement , but the
resultset is lost after that .
So where shoud i close the statement ?Don't keep ResultSets around! See this whole thread:
http://forum.java.sun.com/thread.jspa?threadID=788017
You should:
1. Open connection
2.Open statement
3.Get ResultSet
4.Convert ResultSet into something better
5. close ResultSet
6.close statement
7.close connection
8. return the "something better you converted the ResultSet into"
Of course 5,6,7 should be coded in a way they ALWAYS get executed regardless of any exception may occur (for example in finally block).
1 to 8 may also be replaced by (unless your purpose is only to learn JDBC basics):
1. use some kind of high level framework/library/standard (Hibernate,Ibatis,JPA if you use Java 1.5+... you name it, there are as much as you may need, or maybe even a few more!)
Hope this helps,

In java/jsp got Error,ORA-01000: maximum open cursors exceeded,

Are you actually closing the connections, resultsets in all cases?
From what you've posted you call
rs_admins.close();but in that method, you propagate any exceptions that occur out to the caller method, which in turn just prints a stack trace.
So if an exception occurs before you call the rs_admin.close() the result set will never be closed as the statement won't be reached.
I'd add a speific exception handling routine to the admin_getAdmins() method and include a finally clause to close the result set in all cases. You can still onthrow the exception if you want.

How to analyse the number of open cursors being used by each program?

Hi,
I am getting an error "ORA:1000 Maximum Open Cursors Exceeded" in my
application. I want to analyse and monitor that how many cursors are
being used by each program running in a particular session. I have
already set the Open Cursors Count double of the recommended for my
application, yet I am getting this error.
Is there any tool to analyse and monitor the number of cursors being
used by each DB call?
I have installed SAP NW 7.0 and Using Oracle 10g as DB.
Your immediate help will be greatly appreciated.
Best Regards,
Smriti.

You can list the open cursors per session and check which one uses the most with sqlplus:
SQL> select a.value, s.username, s.sid, s.serial#
from v$sesstat a, v$statname b, v$session s
where a.statistic# = b.statistic# and s.sid=a.sid
and b.name = 'opened cursors current';
Values over 300 are unusual.
It is quite possible, that you see several workprocesses using a lot, because workprocesses are kind of shared sessions.
Cheers Michael
Edit: ah, our posts crossed, obviously there is no workprocess in the java world

ORA-01000 maximum open cursors exceeded with XA driver

We are getting ORA-01000 maximum open cursors exceeded error from Oracle database
agian and again.We are usimg XA driver.
What is the weblogic's work around to handle this error?How we can handle this?We
tried doing "grant select on DBA_PENDING_TRANSACTIONS to public ;" ,this also
works for some time only.Again the same error starts coming.
Help please.
Thanx in advance.

Thanks for your reply.
I have increased my cursor size to 2000(default 300).We are using weblogic6.1
and Oracle9i.Yes I was little aware about this bug so I tried doing "grant select
on DBA_PENDING_TRANSACTIONS to public " from sys and no of open cursors reduced
drastically but aftter some time increased again.We are using combination of thin,XA,non
XA and oci drivers.
We are using weblogic security framework also in our application and I think that
consumes maximum no. of cursors.
Kindly advice.
Thanx a lot.

What is the size of cusror set in your oracle init.ora file?
What version of oracle thin driver and weblogic are you using?
Please read the following note:
There is a bug with Oracle 817 driver's XAResource.recover implementation:
it
ignores the flag and always return all in-doubt Xids. After initially
calling a resource's recover with TMSTARTRSCAN, TM subsequently calls
the
resource's recover with TMNOFLAGS until no more Xid is returned. Thus,
Oracle driver's XAResource.recover is called infinitely until eventually
it
returns XAER_RMERR. Subsequent XAResource.start then returns ORA-01000
exception (looks like all their XAResource methods internally uses prepared
statements to execute some stored procedure.)
Is this the case wth you?
