Maximum open cursors exceeded - after update to 1.1.1.25

While browsing around a database I keep getting "Maximum open cursors exceeded". The only cure is to disconnect and reconnect. This doesn't happen in the prior version (1.0.0.15).

Dear Product Development
I posted a thread about this and a previous version but I am now getting it more and more often in the new version.
When it happens I get a JAVA log window popping up with the following information in it.
Level X
Sequence     130
Elapsed     0
Source oracle.dbdev.oviewer.table.DataEditor
Message      _getTableData
Is this any help to the product development team in diagnosing the issue.
Cheers
Chris

Maximum Open Cursors Exceeded - Oracle 9 & Java Web Server 6.1

We are facing this problem - maximum open cursors exceeded after migrating our application to Sun Java System Web Server 6.1
We were not facing this problem with our earlier web server
Can anybody let us know - is there any setting we need to do to avoid this.
The current setting for this attribute in the database is quite huge - close to 2000
One of the "webservd" sessions, (web server user) exceeded this value

See my reply in your duplicated post:

Help needed, getting ORA-01000: maximum open cursors exceeded

CJ or anyone that may have come across this problem in the past, I hope that you may be able to help me
I am trying to implement a function from the Salesforce PHP tool kit that runs against a class that returns a object of ID's that have been updated in a given time frame.
This is a lot of code. I am sorry for that:

Getting ORA-01000 : maximum open cursors exceeded problem

I am getting ORA-01000 : maximum open cursors exceeded problem in my piece of java code when the
load is high .Open cursors is set to 1000 still getting the same problem .
Basically i have to select some rows from a table which i am doing in A() function and process it and insert into
another table which i do it in another function B() there is a update statement also in this fun.
There is a particular business logic for which i need to call B() from the A() function
which happens to be in the select result set like below
A()
query ="Select * from temp";
while(rs.next)
B();
All the result sets are properly being closed that too in finally block.
I dont see any other problem with code .Still I am gettin this cursor problem.
Is some thing wrong with the design like calling a
insert from a result set while loop or the update statement

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

Here every time the loop executes, a new statement object is created and assigned to the same statement object reference pstmt4. So finally when u r closing the stmt objects, only one stmt object gets closed out of prod.getChannelIDsInt().length that gets created with in the loop.

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.

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.

More on "maximum open cursors exceeded"

It seems a lot of people have been seeing this error message, but reading through the posts on the topic hasn't given me any new insight on the problem. Here's an account of my particular situation:
I am using the XSQL servlet, v.1.0.0.0 with the thin jdbc driver v.1.x. The servlet is running within an Apache server (1.3.12) on a Linux box, and the Oracle database (8.1.5) is located on a Solaris 2.6 machine.
The servlet accepts HTTP connections, performs the corresponding SQL queries and returns the output from the database to the HTTP client. Here's a simple example:
(Sorry about potential bad line breaks.)
client request:
% telnet xsql-host.some.domain 80
Trying xxx.xxx.xxx.xxx
Connected to xsql-host.some.domain.
GET /xsql/test/listall.xsql
<server response here>
listall.xsql:
<?xml version="1.0"?>
<page connection="boss" xmlns:xsql="urn:oracle-xsql">
<accounts>
<xsql:query tag-case="lower" rowset-element="" row-element="accountinfo">
select * from test
</xsql:query>
</accounts>
</page>
Very simple stuff indeed. Now, this has worked perfectly for 3 weeks or so. During this period, the xsql servlet has been stopped and restarted numerous times and the machine hosting the database has been rebooted at least three times. Then, for no apparent reason (as nothing had changed in the setup described above), I started getting "maximum open cursors exceeded" on every request. Since then, I have been unable to get the system working as it had up until now. I haven't restarted the database and I would like to avoid doing so, because that would not be a valid solution for us if the problem reappeared in production. The maximum open cursors setting in Oracle should be correct, since things were running smoothly before.
From what I can see, the problem could be with the servlet not closing its cursors. One post mentioned that it did, but I would appreciate it if this could be double-checked. Considering the database is the only portion of the system which has been kept running for extended periods of time, it seems to me that this might indeed be the problem.
Confirmation, workarounds, suggestions, patches, or a consolation box of chocolates would all be appreciated.
Thanks,

Check which process is making all the cursors on which database. If it is your procedure, try explicitly closing the cursors. I think the cursors are only implicitely closed after the transaction is ended. If you loop and open a cursor within the loop, that might be the problem.
I also had this problem with Java working over a JDBC connection some time ago on a 815 database. If I recall correctly, that was caused by the JDBC driver and fixed by replacing it with a JDBC driver of 9i.
The following script is what I used previously in a program that can draw a graph from the results. It is ugly, but does the job.
Hope this helps,

Maximum open cursors exceeded when inserting to a remote db

I receive the error:
ORA-01000: maximum open cursors exceeded
ORA-02063: preceding line
from ONTARIO
(where ONTARIO is my remote db) when I am performing inserts from a pl/sql procedure to the remote db. I am performing two inserts from inside pl/sql and then issuing an explicit commit. I checked the open_cursors init param on both the local db and remote db and it was set to 300. I bumped up the remote db init param to 600. I was able to perform more inserts but still received this error.
I thought implicit cursors close themselves, especially after a commit. Do I need to do something special to close the cursors on the remote machine?
Thanks for your time...

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)?

Oracle - maximum open cursors exceeded

Hi! I'm constatly getting the error I pasted below, when this line is executed:
PreparedStatement stmt = connection.prepareStatement(sqlStatement);
'connection' is of course an instance of oracle.jdbc.driver.OracleConnection, and 'sqlStatement' is a normal INSERT statement.
Now, why I'm getting an error that involves cursos if the statement is an insert? One more thing, this error is happening in some enviroments so I think it could be an orcacle server problem (like installation or configuration problem), or it could be the driver, or... I dont know :)
Well, I hope anyone can give me a tipo about this... Thanks in advance.

Thanks a lot for all the answers...
After some tests a made, I found out that in the enviroment I developed the application, the value of the parameter OPEN_CURSORS is 300. I don't know yet which is the value in the test enviroment (where the errors are happening) but I'm pretty sure it is smaller, since I could force the same error in the development enviroment increasing the concurrency of the application (ie, I force the application too many create prepare statements, even much more than the real values the application should accept).
Well, I have to thank you all again...

Maximum Open Cursors Exceeded - Oracle & Java

Is this the problem with Forte or Oracle. I am using Oracle in a network in which i have got a tablespace in the Database server.
How to tackle this problem.

I am using 3 methods preparedStatements
1. execute - returns boolean
2. executeQuery - returns ResultSet
3. executeUpdate - returns int
I am closing the ResultSet object returned by executeQuery using
close() method.
Is this the correct way to close the open cursor.
I access the table attributes using a rs.getString(colNum) and
rs.getInt(colNum)
Even then i am getting the maximum open cursors exceeded message.
Will Oracle open a cursor for execute and executeUpdate which is not returning a ResultSet object .
If Oracle opens a cursor for these two methods, how should i close the open cursor.

Maximum open cursors exceeded prblm , code attached for review

I am getting the following exception in my code
java.sql.SQLException: ORA-01000: maximum open cursors exceeded
My code is as follows
     public ResultSet getFiles() throws Exception
          ResultSet rs = null;
          PreparedStatement pst = null;
          String fileqry = "select * from FILES_SENT where FILESTATUS= 'TOBS' ";
          pst = connection.prepareStatement(fileqry);
          try
               rs = pst.executeQuery();
          catch(Exception e)
               System.out.println("In getFiles" + e );
               System.exit(0);
          return rs;
     public void RUN()
          while(true)
               try
                    System.out.println("opening cursor " );
                    FileResultSet = getFiles(); // polling the DB for new messages
                    if (FileResultSet!= null && FileResultSet.next()) // if new files are found
                         do // for each of the records
                              String Filename = FileResultSet.getString("FILENAME");
                              System.out.println("Processing the file " + Filename);
                              // getting the messagetype from the filename
                              String MessageType= Filename.substring(0,1);
                              String InternalMessageID = getInternalMessageID(MessageType);
                              System.out.println("internalmessageid of the file " + InternalMessageID);
                         while (FileResultSet.next());
                         System.out.println("Processed all messages");
                    else
                         System.out.println("closing cursor " );
                         FileResultSet.close();
                    Thread.sleep(10);
               catch(Exception f)
                    System.out.println("exception in RUN " + f);
                    System.exit(0);
     }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,

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?

Hi,
The issue is different this time after restarting application and database find below.
An exception occured trying to map a column
