HELP !!!! Connection LEAK

In DOCS/Articles, it is mentioned that a TOOL is available to view the LEAKED CONNECTIONS,
NO.OF CONNECTION AVAILABLE......
REF :
http://dev2dev.bea.com/products/wlserver81/articles/Chapman_Gahir.jsp
Can anyone tell me Where this tool is available ? In Docs, it is given that in
PetStore Example, the tool is avialble...But o could not find it...... Bcoz it
is very difficult to know whether a connection leak occured or not....Even after
Forcing Garbage Collector,,, i cannot see any Leaked Connection......
Iam desperate and all my efforts to rule out connection leak is becoming waste..
For the last 1 week iam into this job, and still not able to detect or view the
connection...
I have tried all the methods like,,,
enable connection leak profile = true,
Force Garbage Collection...
But still icannot view any LEAKED CONNECTIONS....PLEASE HELP ME.. Iam getting
mad.........

I dont think there is any such tool provided by BEA to detect connection leaks.
You can use the "enable connection leak profile " which will give Warning messages
whenever a connection leak is detected by WLS Server.
WLS 8.1 also provides an option of
"Inactive Connection Timeout:" in the console which releases the connection into
Pool if the connection is inactive for the specified period of time.
Else you can also use Profiles like JProbe and Optimize it to detect memory leaks.
However if you have properly closed all your connections you are not likely to
any connection leaks unless there is an issue with the JDBC Drivers.

WLS 10.3.0 - Connection Leak on JDBC Data Source.

We are observing connection leaks in our environment.
We have enabled connection leak profiling. however we are unable to analyze the output.
Need some help in analyzing the Output.
Also are there any specific way to gather the exact stack trace, to get more detailed information about. Where exactly the connection leak is occurring.

Hi,
Could you enable the following debug flag:
-Dweblogic.Debug=weblogic.JDBCConn -Dweblogic.JDBCConnStackTrace
Also, following is the sample way to minimise the connection leaks. Could you please chk the following:
<JDBCConnectionPool CapacityIncrement="5"

Tools and/or techniques for locating a connection leak

I am working on a application that has been hanging periodically. A thread dump showed many, many threads that had called getConnection() were in WAIT state. So it appears that there is a connection leak.
This application is about 50% legacy code from around 2003 and 50% new code. The new code uses Spring JDBC support so I doubt that the connection leak is there because there is no explicit getting and closing of connections. The legacy code is full of strange and hard to understand logic involving connections so it is the prime suspect.
My first idea was to centralize the get and close and do some logging but the amount of work would be enormous so I'm wondering if there are tools and/or techniques that would make this job easier.
I thought YourKit might be the answer but I did not see anything about connection leaks in a cursory look at the user guide table of contents.
So, I would welcome any suggestions.

I have heard that there is one such tool provided by BEA Weblogic itself but i do not know what is exactly and how to use it.
I would highly appreicate for your help in this regard.Here is a set of RNT (Really Nice Tools (c) mine :) for automated bug detection:

I'm looking for some help connecting linksys IP Cameras to my home network to monitor my property when I'm travelling. I used to do this with linksys WAPS, but since I've discarded all my old linksys networking and standardized on airport, I can't get these things working. I know that I have to identify my camera through the DHCP table and set up port forwarding and there is the problem.
My network consists of 4 base stations set up in a roaming network - same network name and passwords. I need to do it this way so I don't have to switch network when I move from one side of the house to the other, go to the cabana, or my shop in the barn. The network works pretty well since I went to a roaming set up. Good performance, yata, yata, yata.
However, the roaming network requires the AEBS's to be set up in bridge mode, rather than sharing an ip address. When the AEBS is set to bridge mode, you don't see a DCHP table or have the ability to identify your IP Cam through the AEBS - and hence, no port forwarding.
I am able to identify and set up my Linksys IP Cam by locating the ip address on my FIOS router, even though, it's plugged into an AEBS. I set it up, see the video, remove the ethernet cable from the IP Cam, restart - and I can't get to it from an AEBS. In researching this, it appears, I should be setting up the AEBS to "share an IP Address", going to the DHCP table and identifying the camera's IP address and setting up port forwarding. However, you don't see any of the DHCP or port forwarding options in Airport Network Utility when configuring in bridge mode.
I'm hoping I'm missing something here and that the solution isn't to set it up at the FIOS router level, but I'm beginning to think that's my only hope. What concerns me there is that I should be able to see the IP cam on the network without port forwarding since I'm not coming from outside, and I can't even do this unless it's connected hard wire.
I'd appreciate any insight into this that anyone might have. I've hit the wall with what I know.
Thanks.

In a roaming network, your "main" router is the device that would require port mapping/forwarding to be configured in order to access the IP camera from the Internet. This router is also the one that would be provide the private IP address for the camera which you will want to be a static one.
So as you described your network, the IP cameras should be getting an IP address or you assigned it a static one and this is the address that you would enter in the Private IP address (or equivalent depending on the router used) field when setting up port mapping.
If you are not able to access this camera from the local network, then this should be troubleshot first.

Need help connecting a windows network printer to my Mac (Xerox Phaser 3600) over a windows home network

Need help connecting a windows network printer to my Mac (Xerox Phaser 3600) over a windows home network.
My Mac runs lion and the windows desktop runs Windows XP
I have tried for a few hours or so to connect my mac to this printer over a home network.
For your information it does work when connected directly to my mac using a USB Cable.
If there is no soultion could I have help getting the drivers for a Dell All-in-One Photo 926

In most cases you can connect to the Windows shared printer from the Mac. But there is a dependence on the Mac driver being compatible. For many consumer inkjets, the vendor created driver cannot be used for this type of connection so you need to look at alternative drivers, such as Gutenprint or PrintFab. If you can tell us which brand and model of printer you have shared from Windows then we can answer your question with the preferred procedure on the Mac.

AppM File Passivation SQL92 Flavor for DB2 and causes Pool connection Leaks

I am porting an ADF application to WebSphere and DB2 and noticed AM passivation goes from file to database. I have bc4j setup to use file passivation. When this happens I am noticing Connection are not being returned to pool. Has anyone experienced these 2 issues (Connection leaks and AM passivation to database)
bc4j settings below are in place.
-Djbo.doconnectionpooling=true
-Djbo.txn.disconnect_level=1
ADF Version: 11.1.1.59.23 ::: JDEVADF_11.1.1.4.0_GENERIC_101227.1736.5923

BC4J is configured to perform file passivation instead of database. The temp files (BC59c10e3cBCD) are being created, but the application occasionally passivates to database.

Yes there are nested AMs in this case. I have a SQL92 flavor with Type Map set to Java, and running against a DB2 database. I have used reference site
http://www.oracle.com/technetwork/developer-tools/jdev/multidatabaseapp-085183.html
to properly configure my projects and setting and jbo options. What I am looking for is verification on the correct setting when this combination is used. I have dumped the runtime setting below. Are there any obvious problems below that may cause this behavior?

Finding and Reporting Connection Leaks Web Application.

So we have a web application that we know has connection leak(s). I have developed a test plan with JMeter to load test the app, but how do I find and report the connection leak, and what is the best tool to use for that? Basically my test plan runs through a use case scenario. I have added different types of listeners using jmeter to report different types of information that I get back.
Also, is there a way to get the report back as a jsp, html page? Something kind of like the JUnit test reports do
I would like the jmeter test to run, give the url, name of task-maybe, the time it took, success or fail, and current status - connected?
Thanks in advance.

What connections are those - sockets, database, ...? Actually, that doesn't probably matter. I'd use "grep" to find leaks of any kind. Every critical resource should be handled with try/finally:
    foo()
        WhateverConnection connection = null;
        try {
            connection = ConnectionFactory.openConnection();
            ...use it...;
        } finally {
            ConnectionFactory.close(connection); // Static function so that works with null
    }That goes for files, db connections, sockets, everything.
Then any use of openConnection() that doesn't match that pattern is wrong and must be fixed. "grep" plus visual inspection should do it. They may be other pieces of code that are technically correct but look different; those are to be considered bugs and must be modified to conform to the exact same code template. All connection openings must look the same; the code audit easily misses bugs if each developer comes up with his own clever pattern.
Finding leaks by testing will never find them all. Especially leaks that occur due to exceptions. try/finally is the right way to deal with those.
Additionally, the connection factory could keep a list of open connections, and list them at request. I also like to log statistics periodically from the connection pool: how many connections have been opened, how many are open, how long min/max/average time a connection gets used, how much data are transferred, etc.

How to know whether a connection leak occured in weblogic8.1

How to Know whether Conenction Leak has Occured or Not ??..Where does the WeblogicServer8.1 print the STACK TRACE if connection Leak has occured ? or does it maintain a LOG FILE , where any entries can be seen................

To turn on Debug flags add these to the startup scripts.
-Dweblogic.Debug=weblogic.JDBCConn="true",weblogic.JTAJDBC="true"
Essentially, you will need to edit the config.xml file (when the server is down) and add the proprty to the ConnectionPool definition:
http://e-docs.bea.com/wls/docs61/config_xml/mbeans.html
ConnLeakProfilingEnabled="true"

Connection Leak with SP3

Hi-
I recently moved from 8.1SP1 to 8.1SP3 and WOW am I getting a lot of connection leaks. I never had this problem at all with SP1 and I'm quite concerned.
My app is probably 98% CMP but I do have a bit of direct access.
My app supports both Sybase and Oracle and I get the same leak warnings with both. Other than being annoying in the console however, it doesn't seem to have any ill effects .
Here is the warning:
<Nov 8, 2004 2:35:54 PM EST> <Warning> <JDBC> <BEA-001074> <A JDBC pool connecti
on leak was detected. A connection leak occurs when a connection obtained from t

Error in finder method wrapper resulting in a connection leak

we ar using OC4J 1.0.2.2.1 and dicowered some problems with connection leaking.
The same was reproducable on 9.0.2.1 and 9.0.3 (the "J2EE 1.3 certified" version).
Using CMP/CMT for Entity EJB.
If we define the transaction attribute for a finder method returning single object as NotSupported
and ObjectNotFound exception is thrown as a result of call to the finder method,
connection is not closed.
With emulated datasource this results in a connection pool overflow, with XA datasource
the console gets conenction not closed exceptions but at least connections are closed (seriously influencin performance while waiuting for connection timeout).
the same code executes with no problem on JBoss 2.4.x and 3.0 and on iPlanet.
any comments on this - is this a bug or feature ?

Please log a TAR with your support repesentative so that we can drill down on this issue. As described, this does not sound like the correct behavior but until the details are examined it is hard to tell.
Thanks -- Jeff

Connection Leak Exception in farm runs

Hi
I am trying to use the ADFBC to get a list of values for my backend data which will be displayed in the UI later. In the view, it works fine. There have been no errors. But during the farm runs there is an intermittent issue of the Connection Leak Exception.

The scenario is that I launch a page which has a region. This region needs to get a list of values from the backend. These values are coming from a VO.
This issue happens only in the farms and I guess at times from the view, but doing a bounce of the server resolves the issue.
Is there any setting that needs to be done ?
Thanks
