Java Pug-in 1.4.1_02 not closing sockets using URLConnection
I am developing an applet that accesses a URL to get data to be displayed on the screen (Apache, mod_plsql). The problem is that when I execute the applet using "appletviewer" in my machine, each URLConnection shares only one socket connection to the WEB server. When the same applet is executed in the browser through the Java Plug-in 1.4.1_02, each URLConnection creates a new socket connection. Is there any bug? Is this a matter of configuration? Browser version? To test the applet I am using Forte for Java 4CE, JDK 1.4.1_02 (the same version as the Plug-in). I have tried many things already without success, there are no error messages in the server nor any exception on the applet. Both my machine and the server are Windows 2000 SP3.
Have you found a solution to this? I'm having a similar problem with URLConnection always starting a new socket connection when run from within the Java Plug-In.

Cursors are not closed when using Ref Cursor Query in a report ORA-01000
Dear Experts
Oracel database 11g,
developer suite 10.1.2.0.2,
application server 10.1.2.0.2,
Windows xp platform
For a long time, I'm hitting ORA-01000
I have a 2 group report (master and detail) using Ref Cusor query, when this report is run, I found that it opens several cursors (should be only one cursor) for the detail query although it should not, I found that the number of these cursors is equal to the number of master records.
Moreover, after the report is finished, these cursors are not closed, and they are increasing cumulatively each time I run the report, and finally the maximum number of open cursors is exceeded, and thus I get ORA-01000.
I increased the open cursors parameter for the database to an unbeleivable value 30000, but of course it will be exceeded during the session because the cursors are increasing cumulatively.
I Found that this problem is solved when using only one master Ref Cursor Query and create a breake group, the problem is solved also if we use SQL Query instead of Ref Query for the master and detail queries, but for some considerations, I should not use neither breake group nor SQL Query, I have to use REF Cursor queries.
Is this an oracle bug , and how can I overcome ?
Thanks

AS Java sessions are not closed until they time out
Hello Experts,
we have a SAP PI system to integrate SAP R/3 with external applications and recently we are facing a problem with inactive sessions. There's a new application we are setting up that consumes a webservice published by this SAP PI system. The scenario is SOAP --> PI --> PROXY. What we have noticed is that when the application sends loads of requests sometimes the system fails. This is because we are reaching the maximum number of open sessions in AS Java (1000). Investigating a bit more we found out that the sessions are not "closed" once the communication between the application and SAP PI has finished. Those sessions are open until they are automatically timed-out by the system after 1800 sec.
We have found the notes below in SAPNet:
Note 1363751 - ICM: Java Web sessions are not terminated
Note 1307940 - New HTTP session opened for every web service call
However, none of them are applicable to our system because it is more updated:
SAP PI 7.1 EHP1 SP002
Kernel Patch Level: 87
We have tried to close connections from the application that consumes the webservice but with no success. The sessions remain in the server until they are timed-out. Could you please tell us if this is the normal behavior of an AS Java system? Is this the way it should work? If so, can you tell us how to decrease this timeout so the inactive sessions are cleaned faster? We tried to find it but we didn't manage. Is there any way to close the session once the communication has finished?
Thank you in advance.
Roger Allué i VallHi Roger,
You can do the following things to help solving your issue:
1. Decrease session timeout default value of the web container: Use the NetWeaver Administrator
Open Application Modules plugin within NWA
Configuration Management -> Infrastructure -> Application Modules
Set the desired timeout web module you are using, in minutes.
The default value 0 in the NWA means that the value is not modified
and the default value of 30 minutes timeout will be used.
2. Increase the max. no. of Sessions in Configtool
The max. number of Sessions can be set in Configtool in the Expert
mode. There is no limitation for the parameter.
Thanks,

Logical error with Sockets, not closing properly
Hi again everybody, I am still in need of help it seems. I have been working on a way to transfer files from computer a to computer b but I cannot get the Sockets/Streams to work properly!
The problem I keep getting is "IOException: java.net.SocketException: Software caused connection abort: socket write error"
According to some threads in this forum its either because of a firewall blocking or because of an error such as the client trying to write to a stream that is closed in the other end ( or something like that, I cannot remember 100%).
The thing is: I am only getting this the second time I try to send the file, the first time it works just fine.
I can solve the problem by restarting the server (resetting the socket) after every time I send the file but that is not a solution, but merely a confirmation that I indeed have a bug.
Can you please have a look at my code and point out where I missed something? I have been staring blindly at the code on and off for over a day now.

Follow-up question, need more information to solve the problem:
My server now uses a ObjectOutputStream to send packets to the client, which successfully reads them BUT:
the problem still remains! I am still getting a "SocketException socket write error" the second time I use the sender!
Right now this is what the send-method in FileSender looks like.
(Look at "// Connection Loop" for the biggest change.)
What am I doing wrong here?

thanksI just had the same problem this morning. I believe the app server starts and if you browser directly to your app you'd get it, but the connection between the appserver and the IDE is somehow lost. An easier solution than completely reinstalling for me was to delete the .Creator folder in my home directory (C;|Documents and Setting\<username>\.Creator) and restart Creator

JMS session is not closed even after calling close()
Hi All,
I am using JMS to receive and publish topics for a process,in my java code i
am creating new JMS Session on demand(ie., whenever a new topic is
received) after processing the topic i am closing the session with close(),but
still the session is not closed.In a period of time more sessions are created
and FD leaks occurs which stops the process functionality.
Later i moved the on demand session code to a static block, its working fine
and no FD leak occurs.
Is this a known behavior or any java bug is there to point this issue,please
help me regarding this.
Thanks,
Ants BalajeiYou should try avoid creating sessions on demand but cache/pool them...

Due to the logAbandoned and removeAbandoned settings, I get a report in my log file whenever there is a connection that was not properly closed. Here is one of those log entries:
23:22:51.483 (10) Finalizing a Connection that was never closed:

at edu.calpoly.lib.multimedia.big.game.AutoUpdateThread.run(AutoUpdateThread.java:155)
The file: AutomaticPeriodUpdateIBatisImplDBHandler.java contains an iBatis call on line # 154:
--> list = sqlMap.queryForList("getGamesWithAutoPolicy", null);
from the map file:
<select id="getGamesWithAutoPolicy" resultClass="java.util.HashMap">
<![CDATA[
SELECT gameid, policy
FROM update_policy
]]>
</select>
Here is the code for the entire method that uses this transaction:
============================
public List getGamesWithAutomaticUpdatePolicy() throws BIGDatabaseFacadeException
List list = new ArrayList();
try
sqlMap.startTransaction();
list = sqlMap.queryForList("getGamesWithAutoPolicy", null);
sqlMap.commitTransaction();
catch(SQLException sqle)
throw new BIGDatabaseFacadeException(sqle);
finally
try
sqlMap.endTransaction();
catch(SQLException sqle)
throw new BIGDatabaseFacadeException(sqle);
return list;
============================
I know that this should be handled as an automatic transaction, but I tried adding the start, commit and end transaction commands in my desperate attempt to fix this problem (but it still didn't help).
Here is my code for creation of sqlMap -
--> sqlMap = SqlMapClientBuilder.buildSqlMapClient(Resources.getResourceAsReader("sqlMaps.xml"));
Except for the fact that occasionally connections are not closed, overall my database access using iBatis works very well.
In the course of trying to fix this problem I've worked to update all my lib files to the latest versions, and here is current status:
My iBatis lib file: ibatis-2.3.4.726.jar
My JDBC driver: postgresql-8.4-701.jdbc3.jar
Required commons files:
commons-dbcp-1.2.2.jar
commons-pool-1.5.3.jar
Note that I tried adding --> commitRequired="true" to the transactionManager in sqlMaps.xml, hoping it might help, but no joy.
Please help me figure out why my database connections often do not close. Thank you very much!I'm sorry, but I don't understand what you mean by "close the session." I believe iBatis is supposed to take care of all that automatically. My understanding is that all the user does is create the sqlMapClient and then use it along with various map files to query and update the database. iBatis does the rest.

DriverManagerConnectionPoolConnection not closed with TopLink cahce synch
We're using TopLink in several JVMs and have configured cache synchronisation over JMS. The JMS topic runs on Oracle AQ. Every once in a while we get the follwoing error from OC4J:
DriverManagerConnectionPoolConnection not closed, check your code!
Now this could be some connection we forget to close, but we do use TopLink for all our databasecommunication. I also see that every time it shows up the last steps of the stacktrace involves the TopLink cache and the AQ classes:

For those of you familiar with the Spring Framework you'll notice I'm invoking an SLSB throug it, and that thet start of the stackrace is missing, but this error also shows up in other contexts. This is only one of them. They all have in common the AQ and Cache sync lines.
Anyone have any ideas? Is it even tied to TopLink or might it be an AQ issue?
Anders,What version of OC4J are you using?
If you are using a 10.1.3 preview release, this may be an issue with OC4J connection pooling in that preview release.
You could try using AS JMS and TopLink connection pooling to determine which is causing the issue. -
Connection not closed in the database server end
Hi,
Our database server (sql server 2000) and java application are running in two different boxes. Because the java application sent to the db server quite a few queries that can not be completed (applications hangs there) due to huge amount of data (18 million records in one table and 1 million records in another table and there are joins among the three tables), we stopped the java program. However, in the db server end, the connections associated with these problem queries were not closed although the java app end already closed these connections by calling connection.close(). When this happened, we have to manually close the connection from sql server enterprise manager.
Here are the questions.
1)what could be the reason why db server does not close the connection?
2)Is there any solution in the java end that could close the connection in the db server end when this situation happens? I say this situation happens, I mean in most cases when java application closes connection, db server closes connections in its end too.
Thanks

Thanks for your answers and questions.
Here are the answers to your questions
1)The jdbc driver is jturboJTurbo? Never heard of it. You mean this?
http://www.newatlanta.com/products/jturbo/index.jsp
Why pay for something when you have two options available that are free? One of them is from Microsoft itself. Whose idea was this?
2)It's a desk top application.
It seems to me that it should not be driver issue. I was this happened the Microsoft's own jdbc driver. By jdbc specification, although you don't close the connection explicitly in the program, the connection will be automatically closed in the java app end during garbage collection. Very bad - never depend on this. Always close your ResultSet, Statement, and Connection in reverse order of opening in a finally block, each one wrapped in individual try/catch blocks.
One should never, ever depend on the GC to take care of resources like database connections or resource handles. Those should be cleaned up by your code.
I tested this by intentionally not closing a connection. When I stops the application, the connection in the sql server end was also closed.
But if you don't close the application and fail to close connections, you can see where eventually you'll exhaust the pool.
It seems to me this is a sql server issue rather than a jdbc driver issue. I need way to prove this.
Like I suggested, it's easy to swap in the jTDS driver and try it again. What do you have to lose?
Or call Microsoft support and ask them. Or maybe JTurbo. You're paying for it - might as well use the support.

TopLink logical connection not closed
Hi everybody,
I have a problem when using db adapter for polling databases tables. This is using TopLink to access database's data.
My process was running w/o errors till I have started to use external data source defined in OAS.
My oc4j-ra.xml file contains:

Any clue on this?
Thankfully,
amoThanks Marc,
I have finally noticed that was not related with some TopLink error.
So, is there any other way to refer in the DBAdapter to an OAS datasource?

>Hello,
I recommend not the xmlpull jar file, but the xpp3-*.jar file found with your Enterprise installation. It's in the "external" subfolder where you got your other Enterprise jar files.
You'll have to remove the xmlpull jar, since they'd version conflict.

ServerSocket not closing...JRockit Bug?
The following sample program does not behave as expected with JRockit, but works
fine with Sun JVM.
import java.net.*;
import java.io.*;
public class SocketTest {
static ServerSocket soc = null;
public static void main(String [] args) throws Exception {
int port = Integer.parseInt(args[0]);
soc = new ServerSocket(port);
Runtime.getRuntime().exec("notepad");
soc.close();
System.exit(0);
When this program is run with JRockit JVM, till I close the notepad, the server
socket is not getting freed even though the parent process has exited!! But, with
sun jvm as soon as the parent process exits, the port does get freed.
Isn't this a BUG?
Rgds,
ThiruI am able to reproduce the problem in JRockit 8.1. I can see that the socket
is not getting released till the notepad is closed by using netstat.
I am not sure about the version that you are using. There is no 1.4
compatible version in JRockit 70SP4 (its only 1.3 compatible). If you want
to use 1.4 compatible, you need to upgrade to 8.1
This issue is fixed in 81SP1 (CR102658). Please download 81SP1 (1.4.1)and
try.

Hi,

In fact after running the test program, before closing notepad, if you runanother
program
that tries to bind to the same socket, it fails.

Hi,
Thanks for the reply.
I had tried that too, it did not work.
Below is the code.
import java.net.*;
import java.io.*;
public class SocketTest {
static ServerSocket soc = null;
public static void main(String [] args) throws Exception {
int port = Integer.parseInt(args[0]);
soc = new ServerSocket();
InetSocketAddress isoc = new InetSocketAddress("mymachine",port);
soc.setReuseAddress(true);
soc.bind(isoc);
Runtime.getRuntime().exec("notepad");
soc.close();
System.exit(0);
Even with this, I have the same problem.
I am using JRockit 7.0 (1.4.0) on Windows 2000 platform with SP4.
Please note that the same program works fine with Sun JVM 1.4.1

Thiru,
I'm not sure what you mean by "the socket is not getting freed", can
you
describe in more detail how you did that check? On what platform and
with
which version of JRockit do you experience this?
Could you have experienced problems the timeout state that with your
ServerSocket connection? In that case, you can try to use the
setReuseAddress-method in the ServerSocket class.
In the api for ServerSocket:setReuseAddress in JDK 1.4.1:
setReuseAddress
public void setReuseAddress(boolean on)
throws SocketExceptionEnable/disable the
SO_REUSEADDR
socket option.
When a TCP connection is closed the connection may remain in a timeout
state
for a period of time after the connection is closed (typically known
as the
TIME_WAIT state or 2MSL wait state). For applications using a well known
socket address or port it may not be possible to bind a socket to the
required SocketAddress if there is a connection in the timeout state
involving the socket address or port.
Enabling SO_REUSEADDR prior to binding the socket usingbind(SocketAddress)
allows the socket to be bound even though a previous connection is in
a
timeout state

OC4J AQ/JMS - Logging DriverManagerConnectionPoolConnection not closed
Hi,
Since I do not directly utilise JDBC resource, I cannot work out how I might investigate this supposed leak.
Every now and then (and it does appear to happen sporadically - I cannot identify a pattern), I get the
messages.
DriverManagerConnectionPoolConnection not closed, check your code!
I turned the logging on (using -Djdbc.connection.debug=true), and the following exceptions is thrown:

Here is the matching 'jdbc/ejb/CallistaMessageOwnerDS' datasource definition for the JMS:
<data-source

inactivity-timeout="30"
/>
I would appreciate any input into any mistakes I may have made (perhaps I need to use a different datasource, or define it in a different way)
Any help - including an indication that this is an error I can safely ignore :-) would be appreciated.
Thanks
JasonI'm have the same issue. I'm currently trying to seen if the Oracle 9.2.0.5.0 patch corrects the issue (waiting for the file down load). There is a known issue in Oracle and cleaning up Inactive connections. I assuming the two are related ... I hope it works.

This error occurred with other java files too, but in the code apparently the jdbc connections are closed. I'm searching since a week the problem and different solutions in the forum but this does not apply for my problem, please help me.
Regards
Jeanette.Thanks Frances, but I set -Ddatasource.verbose=true and get some like this:
Releasing connection com.evermind.sql.DriverManagerXAConnection@1cf6046 to pool (Pool size: 5)
com.evermind.sql.OrionCMTDataSource@1a9a15f: Cache timeout, closing connection (Pool size: 4)
com.evermind.sql.OrionCMTDataSource@1a9a15f: Cache timeout, closing connection (Pool size: 3)
com.evermind.sql.OrionCMTDataSource@1a9a15f: Cache timeout, closing connection (Pool size: 2)

null: Releasing connection com.evermind.sql.DriverManagerXAConnection@6409e1 to pool (Pool size: 1)
I suppose that some connections were closed well and others didn't close in the right form and use cache timeout.
Nevertheless even now I don’t know how to correct the message of connection:
07/01/11 18:31:44 OrionCMTConnection not closed, check your code!
07/01/11 18:31:44 Logical connection not closed, check your code!

07/01/11 18:31:44 at com.evermind.sql.OrionCMTConnectionFinalize.<init>(OrionCMTConnectionFinalize.java:42).........
This time in the log I found other lines before the OrionCMTConnection….:
