OJMS Database Connection Leak
We have configured OJMS for JMS persistence in our application, what we have noticed is that application server seems to open 1 database connection for every new JMS connection. But if the JMS connection is closed the database connections seems to be alive. We are facing some random patterns regarding the connections being open, over a period of time the application seems to run out of database connections since all the connections are being acquired by OJMS.
This is really urgent we are in the post-production phase and this problem is hindering the go-live phase.

Hi Pointer,
Thank you for the reply, we are using 10.1.3 version of application server. We have tested this both on Windows & Unix flavours and getting the same result. As suggested in the documentation we have configured the datasource connection pool accordingly but no result at all.
We have around 20 threads running in the application and each thread acquires a independent JMS connection, what we have noticed is that for every thread in the application App Server is acquiring 2 database connection 1 for the JMS connection and the other for the JMS Destination. So whats happening is the moment the application is deployed and the threads are started we noticed around 40 connection being taken by OJMS. For the connection factory we have configured private connection pool. I dont know where we are going wrong.
-rakeshHi Rakesh,
I believe you may need to look into your application code and check how many connetions are been opened when a single user logins in to your application.Normally this behaviour is managed by OAS when you set Initial/Min cache parameter;however as a workaround try setting DB profile on the database inorder not to overflow the jdbc connections and from application prespective redcue the initial/min cache parameters and increase the Max connections, in addition set a lower inactivity timeout after monitoring the behaviour and response time of your application pages.
If you problem still persists , i would recommend to log on an SR with oracle support.
HTH !!

Closing the database connection after report in a server application
I searched these forums and the internet for a definitive answer on asking the Crystal SDK for java to close the jdbc connection after it has generated a report. We have been using the Crystal Report SDK to generate reports within our JEE application, built upon the Spring framework, for the past two years. It works well, especially if you prepare views in the database for your reports.
From what I can tell once you have used ReportClientDocument to create your report you all the close() method to release resources associated with report generation, but this does not close the jdbc database connection.
Further research states that if you are using the CrystalReportViewer you can call the dispose method to close the database connection. We are not using JSP nor this class, so that does us little good.
Finally I found a post that one could call ((AdvancedReportDocument)reportClientDocument.getReportSource()).dispose(). This doesn't drop the connection either.
Each report actually opens 3 connections according to SQL Server. Each report will reuse the connections it has open, so for 50 reports, theoretically, we could have up to 150 connections. We explained to our client those connections remain inactive, however this is unacceptable to our client as they would like to minimize the number of connections left open to their database.
If anyone can post any further information on this issue, it is much appreciated.Yes, another team member found the issue. Quite embarrassing really I didn't see it. I was looking for the answer within Crystal's libraries. It had nothing to do with Crystal.
The developer who wrote the helper code for using Crystal first opened a connection to the datasource for the live production database and read that connection information for the report. Next he set that connection information in the report template's PropertyBag, then ran the report. The developer however forgot to close the connection he used to look up the connection info, leaving a memory leak and using up all the connections.
I'm glad you inquired. I forgot to post the resolution here. -
The error 600 occurred in the current database connection "LCA".
Hi All,
User is executing job /SAPAPO/TS_REALIGN_COPY in background, as soon as the job is released its failing with runtime error:
I check the Note 1126394 but not relevant.
Runtime Errors DBIF_DSQL2_SQL_ERROR
Exception CX_SY_NATIVE_SQL_ERROR
Date and Time 18.08.2011 00:03:39
Short text
An SQL error occurred when executing Native SQL.
What happened?
The error 600 occurred in the current database connection "LCA".
What can you do?
Note down which actions and inputs caused the error.
To process the problem further, contact you SAP system
administrator.
Using Transaction ST22 for ABAP Dump Analysis, you can look
at and manage termination messages, and you can also
keep them for a long time.
How to correct the error
Database error text........: "POS(1) Work rolled back: BAD_ALLOCATION in
SAPTS_COPY_DA"
Database error code........: 600
Triggering SQL statement...: "EXECUTE PROCEDURE SAPTS_COPY_DATA"
Internal call code.........: "[DBDS/NEW DSQL]"
Please check the entries in the system log (Transaction SM21).
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"DBIF_DSQL2_SQL_ERROR" "CX_SY_NATIVE_SQL_ERROR"
"/SAPAPO/SAPLOM_TIMESERIES" or "/SAPAPO/LOM_TIMESERIESU20"
"/SAPAPO/OM_TS_DATA_COPY"
If you cannot solve the problem yourself and want to send an error
notification to SAP, include the following information:
1. The description of the current problem (short dump)
To save the description, choose "System->List->Save->Local File
(Unconverted)".
2. Corresponding system log
Display the system log by calling transaction SM21.
Restrict the time interval to 10 minutes before and five minutes
after the short dump. Then choose "System->List->Save->Local File
(Unconverted)".
Information on where terminated
Termination occurred in the ABAP program "/SAPAPO/SAPLOM_TIMESERIES" - in
"/SAPAPO/OM_TS_DATA_COPY".
The main program was "/SAPAPO/TS_RLG_COPY_SINGLE ".
In the source code you have the termination point in line 57
of the (Include) program "/SAPAPO/LOM_TIMESERIESU20".
The program "/SAPAPO/SAPLOM_TIMESERIES" was started as a background job.
Job Name....... "/SAPAPO/TS_REALIGN_COPY"
Job Initiator.. "CIBERNLAPO2"
Job Number..... 00015100
The termination is caused because exception "CX_SY_NATIVE_SQL_ERROR" occurred
in
procedure "/SAPAPO/OM_TS_DATA_COPY" "(FUNCTION)", but it was neither handled
locally nor declared
in the RAISING clause of its signature.
The procedure is in program "/SAPAPO/SAPLOM_TIMESERIES "; its source code
begins in line
1 of the (Include program "/SAPAPO/LOM_TIMESERIESU20 ".
Kindly suggest any notes or is any setting needs to be modified.
Regards,
KaasiHello Ada,
the job was aborted due:
Database error text........: "POS(1) Work rolled back: BAD_ALLOCATION in
SAPTS_COPY_DA"
Database error code........: 600
Triggering SQL statement...: "EXECUTE PROCEDURE SAPTS_COPY_DATA"
Internal call code.........: "[DBDS/NEW DSQL]"
Please check the entries in the system log (Transaction SM21).
From the posted dump.
Was it lack of OMS heap memory, memory leaking, program error or huge data selection for application run it's not clear. It will be best for SAP customer to create the SAP message and get SAP support when application canceled due Database error BAD_ALLOCATION in LCA routine.

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

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

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.
orozcomWhat 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. -
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

Exchange error id 74 Connection leak detected for key
I found error on my Mailbox server and can't find any description for this error:

Exch_administrator - this is my user account. Any suggestion what it is can be?Hi,
If you receive an alert that specifies that DataProtection is unhealthy, this indicates an issue that may affect the replication or cluster components, and that can prevent access to the Exchange databases.
To troubleshoot the DataProtection health set, you can refer to the following article.
Troubleshooting DataProtection Health Set
http://technet.microsoft.com/en-us/library/ms.exch.scom.dataprotection(v=exchg.150).aspx
For the FEP health set, it is related to the ForeFront. If you don't have ForeFront installed, you can disable this HealthSet on the server.

return true;Hello Pramod,
>>I have an application in which windows handle count keeps increasing
If the windows handle(I assume you mean the object handles in Taks Manager bar) keeps increasing, it should means that the project keeps allocating new objects and does not close/dispose them. I notice that you are using ADO.NET API, I am wondering how you
manage these connections, do you close/dispose the connection immediately after using them? If not, please do it and it is recommended.
Please check if you call method to close/dispose connections in a finalize method, if so, this is not recommended since in a finalize method, these connections object would still keep alive and does not return to the connection pool, and for new connection
request, application might increase more connection number to meet the request.
You could make a test to call GC.Collect() to test if there is a memory leak, if it has, you could check this
article, or it could be also a handle leak, this
blog might be helpful for it.

I want to simuate Connetion LEAK
Developed a small application having only 1 JSP FILE, 1 HTML only..In JSP file
1 database connection object is used to insert a record into a database.The connection
object is not closed.. So only one connection object...
Enable VIEW LEAKING CONNECTIONS in ADMIN CONSOLE...When the appl is run , record
gets inserted sucessfully.. When the JDBC CONNECTION is right cliked to VIEW LEAKED
Connection, it does not show any message....
I have not closed the connection object. So it should show leaked connection..why
it is not displaying?????.........If this is the case, how can i check whther
a connection leak is there or notSarika Angadi wrote:
Hi,
We are using WLS6.1 SP5 and I am also getting below stack trace. This error is in production enviroment.
Could you please update me soon on this?Hi. I believe it's a false warning, having to do with internally created connection
objects in the context of sending RMI objects from server to server. You can ignore
those messages. This is already fixed in sp6 and sp7. Here is the official sp5 patch.
If you can't get it off this post, call support to get CR131575_610sp5.jar.

Installation problem with NW'04 SR1: database connection failed
Hi all,
while installing NW '04 SR1 on Windows Server 2003 SP1 and MS SQL Server 2000 SP4 I ran into an error related to the database connection. While performing the step "Load Java Database content" SAPinst crashes with the message
com.sap.sql.log.OpenSQLException: Could not load class com.ddtek.jdbc.sqlserver.SQLServerDriver.
The connection to the SLQ Server with e.g. the Query Analyzer is OK. I had a problem with this installation setup before (have a look at the corresponding <a href="https://forums.sdn.sap.com/thread.jspa?threadID=338638&tstart=0">thread</a> ), the JDBC drivers where missing on the installation master but after copying them in the right direction the installation went on with no problem up to this point...
Has anybody an idea what could have happened here? Is this maybe a problem connected to the one I recently had
Below I attached the sapinst.log and jload.log with more detailed messages.

AD Worker error:
The above program failed. See the error messages listed
above, if any, or see the log and output files for the program.

The error says database connection error. I am able to connect to the database using sqlplus. I tried to restart the failed worker, but the same error is repeating.
Any help would be appreciated.

One thing which I noticed now is in the apps Tier the
tnsnames.ora under $TNS_ADMIN
shows entry like this:
PROD=
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=<appsServerName>)(PORT=1521))
(ADDRESS=(PROTOCOL=tcp)(HOST=<dbServer>)(PORT=1521))
(CONNECT_DATA=
(SID=PROD)
)Actually *(ADDRESS=(PROTOCOL=tcp)(HOST=<appsIPaddress>)(PORT=1521))* this line in the tnsnames.ora is not correct. In fact the appsServerName should be replaced with dbServerName
I deleted the tnsnames.ora and reran autoconfig but it is again recreating the same entry.
Any clue how this can be fixed?
Thanks

Problem with having several database connection registered in JDEVElOPER
Hi
Thank you for reading my post
I have several AS registered in my Jdeveloper environemtn and several database connections.
unfortunately some times Jdeveloper can not deploy an application into a server beacause it say that "I failed to create the connection pool", the project has no database stuff at all but Jdeveloper try to register and create connection pools for those connection that i hace registered in the Databse coonnection node.
It fails because in that particular server which i want to deploy the application i have not add all databases JDBC driver.
is there any solution for it?
thanksHi,

Creating new Data Source Error - Database connection Failed
Successfully installed and configured 11.1.1.3.0. Planning and Essbase dev.
Went to Workspace > Administer > Classing Planning Administration > Manage Data Sources > Create Data Source.
Entered all info about the application database , etc. Getting error "The database connection failed" (I was able to connect with no problem during the install)
SQL server 2005 is on the same physical server.
The diagnostic tool shows database connection passed for planning. A new database was created for the new application.
The server event viewer shows these errors.
"Login failed for user 'xxx-hyperion'. The user is not associated with a trusted SQL Server connection."
Group Policy Error "The client-side extension could not apply computer policy settings for 'Default Domain Policy {xxx}' because it failed with error code '0x80070003 The system cannot find the path specified.' See trace file for more details. "
The Group Policy client-side extension Group Policy Services failed to execute. Please look for any errors reported earlier by that extension.
Any help is appreciated.Datasource for the application.
I have created a sql db for this planning application (my datasource). See my first message for more details.
When you create a new planning application, you need to associate it with a data source. Since this is a new install, I don't have any data sources available yet.
So, "To create, edit or delete data sources, click Manage Data Source."
This page lets you validate your connection to the database and essbase server. My essbase server connection validates! The database connection does not validate after I enter all the relevant information.
SCREEN INFO BELOW
Fields displayed with an asterisk (*) are mandatory.
Data Source Name *:
Data Source Description:
Select Database Platform
Microsoft SQL Server
Application Database
Server * :
Port * :
Database *:
User *:
Password *:
Click "Validate Database Connection"
ERROR ---> Database connection failed.
So it does not let me create a data source for my new planning application, so I cannot create a new planning application.
Thanks in advance.
