Maximum open cursors exceeded from Oracle XA Connection pool

I am on WLS 6.1 sp2.
When i leave the server up overnight unaccessed and come back and see in the morning,
I see the following stacktrace on the server console.
I dont think its causing any harm, but is there anyway to prevent this from occuring?

Hi. I think this is an oracle driver problem, in all likelihood.
We test a connection with:
Statement stmt = c.createStatement();
stmt.execute(sql);
Where the string sql is "select count(*) from DUAL" if you named your test table as 'DUAL'.
We obtain no result set, so the driver shouldn't be accruing cursors...
Can you upgrade to the latest oracle driver?
Can you upgrade to the latest version of 6.1?

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...

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.

Maximum Open Cursors Exceeded - Oracle & Java

I am using NetBeans ( Forte 5) for developing an application with Oracle Database. My application makes use of executeUpdate, executeQuery statements inorder to access Database.
After few insertions and deletions of data through the host language( Java), my application stops working. It gives out the error.
java.sql.SQLException: ORA-01000: maximum open cursors exceeded[/b
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 - 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

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,
L.
select
'max cursors',
to_number(value)
from
v$parameter
where
name = 'open_cursors'
union
select
substr(lower(username),1,10)||'('||substr(to_char(ses.sid)||','

s.value
from
v$sesstat s,
v$statname n,
v$session ses
where
s.statistic#=n.statistic#
and ses.sid=s.sid
and n.name like '%cursor%'
and n.name like '%current%'
and not (ses.sid between 1 and 6)

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)?

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,
Riccardo

Hi Jean,
I think this is related to the issue I faced a while back.
Thread: Limit/remove inactive database connections generated by ODI
My solution was to write a custom linux shell script to kill off old ODI sessions in the database. I scheduled this job to run via the crontab.
sqlplus -s / <<!
set feedback off
set trimspool on
set pages 9999
spool /tmp/kill_odi_db_sessions.tmp
select 'ALTER SYSTEM KILL SESSION '''||sid||','|| serial#||''' immediate;'
from v\$session
where username ='<ODI_USER>'
and status ='INACTIVE'
and LAST_CALL_ET > 1800
spool off
exit
sqlplus -s / <<!
@/tmp/kill_odi_db_sessions_$ORACLE_SID.tmp
exit
Hope this helps!

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.

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

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

ORA-01000: maximum open cursors exceeded with Thin and OCI

Hi I have this ERROR :
ORA-01000: maximum open cursors exceeded
ORA-06510: PL/SQL: unhandled user-defined exception
ORA-06512: at line 1
and all the connections show this error, I run the weblogic.Admin RESET_POOL utility
and the problem are fixed !!
Why show this error ?
why with RESET_POOL utility resolve the problem ?
the Oracle Version is Oracle 8.1.7.0 32bits on Solaris 8

Mitesh:
I using testConnOnReserve=true and testReleasedConnections=true specify testTableName
when the errors appear , but increse the open_cusror value to 1200, i think is
not the solution, because the DB and Stored Procedure is used by Cold Fusion ,
is the same Application, in Cold Fusion not show this error u other errors with
380 users on the application.
I check to increse the open_cusror and test the application.
thanks

You should do couple of things here.
First of all you can increse the open_cusror value to 1200 if it is ok
with you.
Secondly, make sure you are using testConnOnReserve=true and specify
testTableNAme
in your config.xml for your connection pool defination.
Thanks,

This is know bug from oracle.
XAResource.recover repeatedly returns the same set of in-doubt
Xids irrespective of the input flag. According to the XA spec, the
Transaction Manager should initially call XAResource.recover with
TMSTARTRSCAN and then call XAResource.recover with
TMNOFLAGS repeatedly until no Xids are returned. This Oracle
bug could lead to infinite recursion and subsequent running out
of Oracle cursors with error "ORA-01000: maximum open cursors
exceeded."
What version of weblogic are you using? What is value for max cursors
in init.ora file
in your dbserver?
Resets the named database ConnectionPool by shutting down and
reestablishing all the allocated connections. This method should
only be called when the connection pool is known to be in a bad
state, for example when the database has been restarted.
By using Reset you are cleaning all bad connections and associated
cursors
with it. That
is why it resolves ora-1000 for you.

JDBC Error: ORA-01000: maximum open cursors exceeded

Post Author: prashant
CA Forum: Information OnDemand
I successfully created reports using CR4E on windows, deployed JSPS to Websphere running on windows and was able to view a large reports for a using JNDI connection resources to Oracle 10g.
Every time report is called, it consume 12 cursors from of the database. Open_cursors count is 300. After 24 or 25 iteration of this report, it throws ORA-01000: maximum open cursors exceeded error.
Has anyone seen this problem, and if so where can I find a hot fix/patch. Any help would very much be appreciated.

The following code reproduces the problem for me. I thought this was just related to when an exception occurs, and close occurs immediately afterwards. Close finds the exception that occured, and throws it without releasing the resources.
It's a pain in the ass, that's for sure.
public void go() {
try{
long startTime = System.currentTimeMillis();
String sql = "Select number_7_0__, char_10__, varchar_5__, varchar2_10__, number_10_5__, float_126__, date_, clob_, blob_ FROM lotsofrows";
Properties connectProps = new Properties();
Driver drv = new oracle.jdbc.driver.OracleDriver();
connectProps.put("user", "borg");
connectProps.put("catalog", "test");
connectProps.put("password", "borgborg");
Connection conn = drv.connect("jdbc:oracle:thin:@142.176.134.166:1521:test", connectProps);
int cnt = 0;
while (true) {
try {
System.out.print("\nTest " + ++cnt + " ");
Statement stmt = conn.createStatement();
System.out.print("execute ");
ResultSet rs = stmt.executeQuery(sql);

stmt.cancel();
try {

stmt.close();

Error ORA-01000: maximum open cursors exceeded

Why Oracle return this error. When I change the OPEN_CURSORS in init.ora from 100 to 1000 without this error.
I want to keep Minimum cursors value. How can I change the Java program ?

Don't create a new callable statement each pass through the loop. Create it outside the loop and set the parameters & exec inside the loop. Close the resultset each time. Close statement after loop.

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
