"java.sql.SQLException: Result set already closed" on weblogic 9.1
Hello together,
i'm using hibernate 3.2.5ga on weblogic 9.1 through a data source with JTA defined to access oracle 10 with the Oracle's Thin XA Driver. Sporadically i get this:

We are using using a connection within a client application (in our case we are executing this from a jUnit Integration test) so could this be caused by the handling of these remote connections?

Hi,
Our application is getting migrated to weblogic 10.3.5 and java 1.6.
We use Ibatis(2.3.0.677.jar) in our application, when i am running my application, I get below exception in weblogic 10.3.5 with TransactionManager as JNDI.
NOTE: This applicaiton runs very well in weblogic 9.2. And I have even tried locally using the JUnit with transactionManager as SIMPLE which works well too.

I have tried several things and had my team do research but we have not been able to find an answer to the problem.
If anyone can offer any insight as to why we might be getting this error it would be greatly appreciated. Thanks!i also have same error during load testing, mainly this error
"Unexpected exception while enlisting XAConnection java.sql.SQLException"
i tried rerunning after increasing connection pool sizes, transaction timeout, but no luck, marginal improvement in performance though
also tried changing the default tracking levl to none, but no luck.
i am with 8.1SP5, how about you ?
do share if you are able to bypass these errors

Hi everyone,
I know that there are already several threats on this issue, but none of them seems to sovle my issue.
Hence, I'll try it again.
JDeveloper: 11.1.1.3.0
Action: Doing a delete of a row in an entity-based view object, doing a commit. Doing the exact same thing again, but now with an error : java.sql.SQLException: Result set already closed
I'm unable to reproduce in a simple case.
I tried to remove the commit statement, without success.
I tried the following code:
Map sessionMap;
BindingContext context;
String currentFrameName;
DataControlFrame dcFrame;
sessionMap = FacesContext.getCurrentInstance().getExternalContext().getSessionMap();
context = (BindingContext)sessionMap.get(BindingContext.CONTEXT_ID);
currentFrameName = context.getCurrentDataControlFrame();
dcFrame = context.findDataControlFrame(currentFrameName);
dcFrame.commit();
dcFrame.beginTransaction(null); Also without success.
This is my original java code:
OperationBinding deleteOper =
ADFUtils.findOperation(OPERATION_DELETEINVOICE);
deleteOper.execute();
List errors = deleteOper.getErrors();
if (errors != null && !errors.isEmpty()) {
for (Object o : errors) {
logger.severe("Error during delete invoice : " + o + "-----" +
o.getClass());
//Committing the transaction
OperationBinding commitOper = ADFUtils.findOperation(OPERATION_COMMIT);
commitOper.execute();
errors = commitOper.getErrors();
if (errors != null && !errors.isEmpty()) {
for (Object o : errors) {
logger.severe("Error during commit delete invoice : " + o +
"-----" + o.getClass());
}Does anyone have any idea's to tackle this problem?
Thank you in advance.
Filip Huysmans.

If getResultSet() returns a non-null, and the first thing yo do afterwards is call rs.next()
it shouldn't throw an exception. Download our latest driver from our site, and make sure it's
ahead of all our server stuff in the weblogic.classpath, by editing the startWeblogic script.

Jsf datatable component + java.sql.SQLException
I get the following error when implementing a JSF DataTable component using
JDeveloper 10.1.3.1.
javax.faces.FacesException: java.sql.SQLException: Io exception: Socket closed
I am able to follow the article in this link:
http://www.oracle.com/technology/oramag/oracle/06-jan/o16jsf.html
I can get the table generated, but it occurred to me that the example in this article does not include logic to close the statement, resultset, and connection. Sure enough, I jumped out to the database and there were numerous inactive connections hanging around from my application.
I added the following code before the return null statement from the article:
finally {
try {
rs.close();
stmt.close();
c.close();
catch (Exception e) {
System.out.println("after close");
So I need to know the proper procedure to closing the resultset, statement, and connection using a jsf datatable component.You need to make sure you're using the Oracle9i JDBC driver, or using the Oracle 8.1.7.2 JDBC driver as I mentioned above.
If you are using JDeveloper9i release 9.0.2 or 9.0.3, the driver you need is in <jdevhome>\jdbc\lib
Otherwise, you can also download the drivers from OTN. -

Please check the connectivity to your database from the datasources.
Also, you can login into the console and check if the connections are good, by doing test connection on the datasource.

Looking for someone to help me to solve this issue.
rcLooking for someone to help me to solve this issue.Maybe you are closing the connections. You might want to verify that you are not doing that. Or if you are that that is the correct way to return the connection to the pool.
Or you could have stale connections. Some databases will time out connections if the connection is no used in a while. (This is a good thing.) But this means connection pools must do something with connections that are not used for a while. The pools usually have a configuration option(s) which allows you to set up a keep alive message which keeps the database from closing the connection. -

Java.sql.SQLException: Closed Statement
I'm having a problem with my Java code trying to access an Oracle 10g database through the JDBC driver using the Oracle XML Publisher.
We generate a number of different reports, but one report consistently fails with the error: java.sql.SQLException: Closed Statement
It only happens in the production environment, which has significantly more data than the test and development environments.
One interesting (!) observation is that the error occurs after 10 minutes to the second (almost). Which leads me to think it is a timeout related problem, but am aware that this could be a red herring.
And finally, the code is being run within a job sheduled using the Quartz Scheduler v1.6.5.
Any help would be appreciated.
Many Thanks
Lawrence

}I have made some progress in understanding the problem...
Basically, your comment about threads made me look at the code from a threads perspective. There are only three objects used, log4j, oracleXML Publisher and hibernate. Discounting log4j, the Oracle object is created, opened and closed within the procedure, so I concluded that hibernate was the most likely cause of the problem (i know, theres an element of educated guesswork in this).
Anyway, I found the hibernate timeouts (all around 300 seconds) and increased them to 3000 seconds... and lo and behold the reports are generated successfully, although some of them take over 20 minutes each.
So, this is a performance problem with the SQL itself:
SELECT service
, reply
, ROUND(SUM(DECODE(op, 3, 0, count))* :uplift,0) x_events
, ROUND(SUM(DECODE(op, 3, count, 0))* :uplift,0) y_events
FROM aggregate
WHERE ref_time >= :period_start
AND ref_time < :period_end
AND feed = 13
AND agreement = :agreement
AND line = 1
GROUP BY service, reply
ORDER BY 1,2
The SQL in question is querying data for a specific month from a monthly partitioned table that contains about 11 million records a month. We currently have 99 partitions.
Executing the sql in Toad / Sql developer / sqlplus takes around 20 seconds...so why 20 minutes?
Looking in the session browser, I can see that the 20 minute query is looking through all 99 partitions where the 20 second query is only looking at 1 partition for the month in question.
I'm not sure if this is heading off topic for the forum thread, but the question now is...
Why is Oracle using a clearly innefficient execution plan when we are using a query with bound variables and how do we get it to use a more efficient execution plan? -
Java.sql.SQLException: Statement cache size has not been set
All,
I am trying to create a light weight SQL Layer.It uses JDBC to connect to the database via weblogic. When my application tries to connect to the database using JDBC alone (outside of weblogic) everything works fine. But when the application tries to go via weblogic I am able to run the Statement objects successfully but when I try to run PreparedStatements I get the following error:
java.sql.SQLException: Statement cache size has not been set
at weblogic.rjvm.BasicOutboundRequest.sendReceive(BasicOutboundRequest.java:108)

at weblogic.jdbc.rmi.internal.ConnectionImpl_weblogic_jdbc_wrapper_PoolConnection_oracle_jdbc_driver_OracleConnection_812_WLStub.prepareStatement(Unknown Source)
i have checked the StatementCacheSize and it is 10. Is there any other setting that needs to be implemented for this to work? Has anybody seen this error before? Any help will be greatly appreciated.

at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:269)Hi. Ok. This is an Oracle driver bug/problem. Please show me the pool's definition
in the config.xml file. I'll bet you're defining the pool in an unusual way. Typically
we don't want any driver-level pooling to be involved. It is superfluous to the functionality
we provide, and can also conflict.
