SQLException: Closed Connection, SQL state [null]; error code [17002]

Hello All,
I am supporting a Java 5 project on Tomcat. We've used Spring and Stored Procedure in the project.
Recently we deployed our application in a GoLive environment and have started seeing Timeout errors in log files. After around two days we also have to restart Tomcat as users are no more able to login to access the application.
Same application runs fine without any timeout issues on another environment.
The only difference between two environments is that the Go-Live env has a firewall between Tomcat and Database and the other environment hosts both Tomcat and Database on same machine (i.e. no firewall).
For GoLive env the only port open on firewall for JDBC connection is 1521 and is used in the connection string url for obtaining the connections.
When there is a Timeout error, the N/w admin guy observed that the JDBC connection was not attempted on 1521 port, but on some random port which is not open on firewall, due to which the Database server logs also do not show entry for this connection attempt as it gets blocked by the firewall.
I am not sure why a randam port should be used to connect when a specific port is mentioned in the connection url? Also what can be making this port switching?
Application uses Apache DBCP with Spring to obtain connections.
Has anyone experienced similar errors?
Any suggestions/help on this issue is greatly appreciated!
Many Thanks,
CD

SQL State S0001 error code 18456 for named sql server : jdbc errors

When I try to connect to named instance of SQL Server 2005,the error I get it
The database user has data reader and writer rights.
I have used sqljdbc4.jar
url is jdbc:sqlserver://SERVER_NAME:1433;databaseName=DATABSE_NAME;user=USERNAME;password=USER_PASSWORD
I also tried using the jtds driver and I get State 28000 error

You might want to make sure that the instance is specified.
For example, when connecting to SQL Server 2008 using DBVisualizer (free) with SingleSignOn authentication, you need to use the jTDS driver AND you have to specify the instance on the server in order to connect.
Instance-less connection requests are rejected with the same error message as wrong password:

Java.sql.SQLException: Closed Connection error when invoking web service

Hi
I've assembled a simple web service for an Oracle PL/SQL package and deployed it on a Standalone OC4J, when I come to invoke it on the Oracle Enterprise Manager screen I'm getting the following returned within the envelope body:
<env:Body>
<env:Fault>
<faultcode>env:Server</faultcode>
<faultstring>Internal Server Error (serialization error: java.sql.SQLException: java.sql.SQLException: Closed Connection)</faultstring>
</env:Fault>
</env:Body>
The function that is called within the database returns a user defined object that consists of a RAW value and an XMLTYPE. The function takes a string as a parameter, when I enter a string that I know will not return an object there is no error in the envelope body, only when there is an object to return does the error appear.
Anyone have any suggestion as to why this is?

I'm no further forward with this: has anyone assembled, deployed and invoked a web service that returns a XMLTYPE?? I know this should be possible but I think there's maybe some manual intervention required with the classes created with webservicesassembler: I'd really appreciate it if anyone with any experience of this kind of thing could help me think this through.

Java.sql.SQLException: Closed Connection: next

java.sql.SQLException: Closed Connection: next
Here's the JDBC SELECT code:
Class.forName(driver);
con = DriverManager.getConnection(url, user, password);
stmt = con.createStatement();
rs = stmt.executeQuery(select_query);
while(rs.next()) /*Exception occurs on this line! */
Here's what I know:
I can connect to the instance using TORA ok.
The SQL query returns rows from TORA.
I believe the connections are ok because if I purposely mess up the syntax, I get back ORA-errors.
I can execute an INSERT statement ok from a servlet.
I'm using the classes12.zip drivers from the oracle jdbc installation directory.
I'm using the default JDK in WSAD 5.1
Thank you all for helping!

Ryan,
I'm only guessing, but I don't think that:
DriverManager.getConnection(url, user, password);is how to obtain a "Connection" object when using WSAD ("WebSphere", right?) -- even though I don't use WSAD, myself.
Is the java code you posted part of a POJO (Plain Old Java Object)? Or a servlet? Or an EJB? Or a JSP?
Remember, error messages can sometimes be misleading.
What Oracle database version are you using?
What platform are you using?
Good Luck,
Avi.

Intermittent java.sql.SQLException: Closed Connection HELP

We are using 10G rac, with jdbc string with failover with ojdbc14.jar thin client. I am getting this intermittent error
I can't understand why, my dba says there are no alrets on dbs. Never had an issue with code base on 9i, and classes12.jar. Using jdk 1.42. Usually when bounce weblogic we are okay, running 8.1sp2. I can't really bounce weblogic when this happens everytime so I need to figure out root cause and a way to fix the pool without bouncing. I tried reseting the pool won't work, funnny thing is other pools connnecting to same db, but different schema are not showing this error. any help would be appreiciated.
Anyone come across this issue Help

Your pool could be faster, without any
bad side-effects, by turning off TestConnectionsOnCreate
and TestConnectionsOnRelease. They don't help. I would
also suggest turning off shrinking. Those changes will
make the pool faster and more stable. I''d like the
stack trace to see if there's any hint about who closed
the connection...

Java.sql.SQLException: Closed Connection from Custom Identity Service

Hi,
Here is an issue I am trying to resolve:
Platform: Oracle BPEL 10.1.2
OS: Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
Please note that the whole thing has been working in other same type of installations (e.g. RedHat, Windows, Developer BPEL on Windows & Linux) but this seems to be something special on this server. Any help will be appreciated:
This actually work for sometime (2-3 hours) and then suddenly stops working even if we don't do any transaction on it.
Thanks,
Bipul Dutta.

I have my application jar on the server, and launch this JFrame application from the browser. ><zen question>
Which particular 'the browser'? What version of what browser running on what OS?
</zen question>
The reason I ask is that it is up to the browser to call an applet's stop()/destroy() methods and if they do not do so - there is almost nothing we as developers can do about it.
If you need such reliable shut down behaviour, it would be best to launch the applet or frame using Java Web Start.

PLSQL webservice eventually gives java.sql.SQLException: Closed Connection

Hi
We have created a web service based on a plsql procedure in jdeveloper 10.1.2.1.0
We deployed the web service to .ear file in jdev and then deployed that ear file to our 10.1.2 app server.
The web service works fine for a short time but then gives
java.sql.SQLException: Closed Connection
The web service is not used frequently so it's possible the connection is timing out. I haven't tested invoking the web service perodically to see if it remains alive.
I tried to follow this note on metalink
https://metalink.oracle.com/metalink/plsql/f?p=130:14:2526430465590485698::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,370209.1,1,1,1,helvetica
Which wants me to make changes to the file <webservice_name>Base.java in our case GPAuditBase.java
My questions are:
1. In the jdeveloper navigator there is a file called GPAuditBase.sqlj but it does not contain all the code mentioned in the metalink note. Specifically the finally{} section. Do I need to edit the generated GPAuditBase.java that is saved in the src folder for the project? That file seems to contain the code mentioned in the metalink note.
2. If so, how are those changes reflected in the ear file that I want to deploy to my app server? Do I change the files in the src folder and then deploy to ear in jdev
thanks

The Network Adapter could not establish the connection Error Code: 17002

Hi,
after upgrade b41 to b49, I get error from subject, without any changes in my app.
This occurs only on Oracle AS, on standalone OC4J application works OK.
I use connection defined in persistence.xml:
<non-jta-data-source>jdbc/MyAppDS</non-jta-data-source>
and can successfully test this connection in Enterprise manager.
Also, I tried all tricks mentioned here:
http://www.websina.com/bugzero/kb/oracle-connection.html
I know, that this is JDBC layer problem, but I am sure, that my connection is OK, and
after downgrade to b48 this problem fall away.
Bye,

How have you deployed your application exactly, i.e. what is the structure of your ear. I use standard war for deploy.
Is the DataSource defined in your server, or your application? Defined on server, test on Enterprise manager passed successfully.
Try using a direct JDBC connection in your persistence.xml (driver/url), does this work?Not work, this same exception.
How do you access your entity manager? (managed, non-managed, jta, non-jta?)non-managed, non-jta.
FYI, I make downgrade to build 48, and this works - it is last version without this problem.
I added some tracing code to my SessionCustomizer:customize():
DatabaseLogin login = session.getLogin();
logger.fine("URL is :" + login.getDatabaseURL());
With build 48, connection defined using toplink.jdbc.* , the output is:

SQLException - Closed Connection

Hi all,
We are getting the following exception in our client code. We need to fix this error. I want to know why actually such exception occurs and what might be the possible solution(s)? Any help will be appreciated.

Ok, can you once do right click on WEB folder under your project folder and click publish once or twice.
And then restart SQL server and also clear console and try.
I hope Connection closed means there is no connection establishing betweem MII and Server defined.
Is this happening only in Dev or in also Quality server?

SSIS 2012: SSIS Error Code "Excel Connection Manager" failed with error code 0xC0202009.

Hi,
This is kind of weird issue that I am experiencing with excel connection manager in SSIS 2012. This issue occurs sometimes but when I close and re-open SSDT (SQL Server Data Tools - newer BIDS) then this issues goes off temporarily.
Just FYI, through SSDT environment I executed the package successfully with both settings Run64bit runtime setting to Yes and No when error does not occur.
So far I have installed
http://www.microsoft.com/en-us/download/details.aspx?id=13255 (Microsoft Access Database Engine 2010 Redistributable).
I still remember for older versions of SQL Server (2005 & 2008) that I have executed Excel connection SSIS packages with Run64bit runtime = false i.e. in 32-bit mode. As far as I know I think Excel 64-bit issue has been resolved with SQL Server
2012 release.
Here is the detail of error message:
TITLE: Package Validation Error
Package Validation Error
ADDITIONAL INFORMATION:
Error at Data Flow Task [Excel Source [2]]: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "Excel Connection
Manager" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.
Error at Data Flow Task [SSIS.Pipeline]: Excel Source failed validation and returned error code 0xC020801C.
Error at Data Flow Task [SSIS.Pipeline]: One or more component failed validation.
Error at Data Flow Task: There were errors during task validation.
Error at Package [Connection manager "Excel Connection Manager"]: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft Access Database Engine" Hresult: 0x80004005 Description: "Unspecified error".
(Microsoft.DataTransformationServices.VsIntegration)
Here are my environment details:
SQL Server 2012 {Microsoft SQL Server 2012 (SP1) - 11.0.3368.0 (X64) } , Excel 2010 (32-bit). I am developing SSIS code on Virtual desktops with Windows 7 32-bit OS.
Also it occurred to me that since Virtual Desktops are on Shared Infrastructure, the source files and SSIS packages (code) can be on Shared drives for e.g. \\<Corpnet>\userdata\<Corp_Users_Grp>\<Username>\Visual Studio 2010\Projects\Integration
Services Project2\Integration Services Project2\Package.dtsx.
Does this kind of Shared drives have any impact to give this issue?
Thanks in advance!
Ketan
P.S.: I had look at this forum question -->
http://social.msdn.microsoft.com/Forums/sqlserver/en-US/903bbe1d-e070-4c43-9d3b-0a5193550029/64bit-error-in-excel-connection-manager-in-ssis

Hi Arthur,
Thanks for your response.
Yes, it looks like SSIS still has bunch of issues with Excel files like as follows:
1) Some times excel source files cannot be parsed by excel source connection manager.
2) For derive column conversion, we can't replace the existing column. rather, we have to add the derived column as " add as new column" which is tough to manage while destination mapping.
3) If an column in excel contains a data which is not of the data type assigned for the column in excel, the excel source reads that data as "null". For the same, we can't validate the data and redirect the erroneous data in reject file. <-- For
this we tried IMEX setting also
4) In multi-tab/sheet excel file, excel source is unable to detect a tab and identify the metadata of the excel.
I am also checking Microsoft connect for Excel issues with SSIS 2012(https://connect.microsoft.com/SQLServer/SearchResults.aspx?SearchQuery=excel#&&PageIndex=22
As worst case scenario, I am thinking of converting Excel to CSV file or Flat text file. (http://www.mssqltips.com/sqlservertip/2772/importing-data-from-excel-using-ssis--part-2/).
Do you think it is advisable to convert Excel into CSV or Flat file.
Thanks,
Ketan

Any help in this regard will be very useful as this is hindering the progress of my work.
Thanks in advance for the help.

I am using BIDS Microsoft Visual Studio 2008 and running the package to load the data from excel .
My machine has 32 bit excel hence have set property to RUN64BITRUNTIME AS FALSE.
But the error still occurs .
I checked on Google and many have used Delay validation property at Data flow task level to true but even using it at both excel connection manager and DFT level it doesnt work
Mudassar

Thats my connection string
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=E:\SrcData\Feeds\Utilization.xlsx;Extended Properties="Excel 12.0;HDR=NO";
Excel 2010 installed and its 32 bit edition
Are you referring to install this component -AccessDatabaseEngine_x64.exe?
http://www.microsoft.com/en-us/download/details.aspx?id=13255
Mudassar
You can try an OLEDB provider in that case
see
http://dataintegrity.wordpress.com/2009/10/16/xlsx/
you might need to download and install ms access redistributable
