Connection pool issues with Mysql

Hi,
I have defined sufficient read connections (50) in the toplink configuration, I am finding toplink is not releasing the connections in Mysql, this is when run from Jboss App server.
Is anyone aware of toplink connection pool issues with MySql?
thanks

TopLink always closes connections, I cannot see how this could occur.
Please include your persistence.xml or sessions.xml. Also ensure you are closing your EntityManager or ClientSession, especially if using exclusive connections.
Also include the exception you are getting.

Error: Creating a Connection Pool: issue with valid transaction levels

Server: SunOS 5.8 Generic_117350-27 sun4u sparc SUNW,UltraAX-MP
App Server: Sun Java System Application Server 8.2
Jar: ojdbc14.jar
Datasource Classname: oracle.jdbc.pool.OracleConnectionPoolDataSource
Resource Type: javax.sql.ConnectionPoolDataSource
[Issue]
Using /SUNWappserver/lib/ojdbc14.jar, when I create my connection pool in Sun Java System Application Server 8.2, I return the following error each time I try to start the domain:
[#|2006-07-28T14:53:56.169-0500|WARNING|sun-appserver-pe8.2|javax.enterprise.resource.resourceadapter|_ThreadID=11;|RAR5117 : Failed to obtain/create connection. Reason : The isolation level could not be set: READ_COMMITTED and SERIALIZABLE are the only valid transaction levels|#]
When I change the value to "SERIALIZABLE" in my domain.xml file, I receive the following error in my server.log:
Caused by: org.xml.sax.SAXParseException: Attribute "transaction-isolation-level" with value "SERIALIZABLE" must have a value from the list "read-uncommitted read-committed repeatable-read serializable ".
So, I'm stuck!
I can't use the values READ_COMMITTED or SERIALIZABLE since the valid values are "read-uncommitted read-committed repeatable-read serializable ".
Case sensitivity matters.
Any thoughts or help would be greatly appreciated.
Thanks,
--Todd

The Oracle JDBC accepts TRANSACTION_READ_COMMITTED and TRANSACTION_SERIALIZABLE isolation levels.
Example:
connAttr.setProperty(“TRANSACTION_ISOLATION”, “TRANSACTION_SERIALIZABLE”);
I'd check with the Apps server folks.

Java Connection Pooling issue with Oracle 10g Express Edition

Hello
I have a Java based web application that uses the Oracle 10g Express Edition database. I am using a connection pool to get connections to the database.
I use the NetBeans IDE and run my web application on the bundled Tomcat server(5.5.7) that comes with the IDE. Though when I initially run the application from the IDE, the connection pool is set up fine, when I recompile my java code and try to run the application again, I get the following error each time:
Listener refused the connection with the following error:
ORA-12516, TNS:listener could not find available handler with the
matching protocol stack.
The logs before the error shows up, indicate that the connection pool object is fine and gives me the number of available connections and the number of active connections and so on, which I have printed from the constructor of the Connection Pool class:
For e.g.:
Cache size = 17
Available Connections = 17
Cache Limit = 1000
Active size = 0
However, if I kill my Tomcat server process and run the application again, it works fine with no error.
I looked around for possible causes and solutions and all I could find
was increasing the processes parameter value in the init.ora file. I have increased the parameter value to from 100 to 20000 now, in increments of 500/1000 each time but it hasnt worked so far.
Someone else suggested that I increase the size of my connection pool; I initially had it set to a minimum limit of 5, an initial limit of 10 and a maximum limit of 1000. However if I set the Initial Limit to anything above 17 connections, I see the following log on the Bundled Tomcat log and my application doesn't run at all:
Log: Loading JDBC Driver : class=oracle.jdbc.driver.OracleDriver ...
Log: Loaded JDBC Driver
Log: Connection with URL=jdbc:oracle:thin:@localhost:1521:xe as username/password
Error code not handled : 0
Exception Message :java.sql.SQLException: Listener refused the connection with the following error:
ORA-12519, TNS: no appropriate service handler found
The Connection descriptor used by the client was:
localhost:1521:xe
// End of log
And the Bundled Tomcat server automatically shuts down.
Again the System.out statements from the Connection Pool class constructor show that the cache has been initialized and that currently there are free connections available in the pool.
E.g.
Cache size = 18
Available Connections = 18
Cache Limit = 1000
Active size = 0
Has anyone faced anything similar? Could someone please suggest what I'm doing wrong here and what I should do to set right this problem?
Swetha

hello, please pardon me, my english is basic. i do of my best. i had the same problem until reading the pdf documentation 2 days for java devvelloper.it is simple, follow this way.
try {OracleDataSource ds;
Connection conn;
ds = new OracleDataSource();
ds.setURL("jdbc:oracle:thin:@localhost");
conn = ds.getConnection("userid","password");
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE);
don't forget to Dowload the user client of oracle Express Edition. do the rest of your program and it will work. take a look to the documentation pdf for java develloper. all it is explained. good look

Connection pool issue with packaged application

we are using 9.2 mp1 for a Oarcle packaged application which is talking to Oracle RAC. In production one
of the RAC nodes went down and we see that the wbelogic connection pool is never able to reconnect
This is a packaged application Bharosa which internally uses hibernate and in turn relies on weblogic connection pool
See a few stuck threads in the logs indicating some prolem with the connection cleanup

Hi. Something is seriously ill there. I would ask that you post a full thread dump

URGENT: Tomcat, Connection Pool - Issue with web.xml & server.xml

Folks,
I am trying to connect to a MS SQL database using Tomcat/JSP but having issues. The code that I am using is as follows:
Context ic = new InitialContext();
DataSource ds = (DataSource) ic.lookup("java:comp/env/jdbc/test");
Connection conn = ds.getConnection();
Statement stmt = conn.createStatement();
I have added the following code to my Server.xml:
<Resource name="jdbc/test" auth="Container" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="DB_AW_DATA" password="tester" driverClassName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
url="jdbc:microsoft:sqlserver://192.168.0.1\\Newcastle"/>
And the complete web.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE web-app (View Source for full doctype...)>
- <web-app>
- <resource-ref>
<description>Resource reference to java.sql.Connection factory defined in server.xml</description>
<res-ref-name>jdbc/test</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
</web-app>
The error message that I am getting is as follows:
java.sql.SQLException: Cannot load JDBC driver class 'null'
What confuses me is that I have placed the following files in Tomcat\common\lib...
mssqlserver.jar
msbase.jar
msutil.jar
I think this is purely an issue with how I configured server.xml and web.xml
In the Tomcat documentation it states to put the code in the server.xml - but nested inside the Context element. This is something that I have not done as I am clear what the Context should be..
Can someone assist...
<Context path="" docBase="ROOT" debug="0"> ???
what should be the path and the docBase.
I have deployed the following application:
http://localhost:8080/SCWAPP/index.jsp
THANKS IN ADVANCE FOR ALL SUPPORRT

you should put the code you typed in server.xml into context.xml
in the META-INF folder and this will fix your problem.
the latest tomcat docs detail what to do.

Connection pooling issue with compiling with jdk 1.5.0

A
javax.naming.NameNotFoundException: Name jdbc is not bound in this Context exception occurs when I run my web app in Tomcat 5 using jdk 1.5. However, I don't get this problem with I use jdk 1.6.0. The mysql connector version is 3.1.1.4 and my server.xml file has been configured correctly. Any suggestions as to why this exception is occurring - I'm assuming it's a version issue but not sure how to solve it!

Use "java:comp/env/jdbc/DbUser" instead of just "jdbc/DbUser" for datasource config
See http://www.tek-tips.com/viewthread.cfm?qid=431734
The mysql connector version is 3.1.1.4Use a more recent jdbc driver

Hello,
It looks like you are using a TopLink managed connection pool and do not have enough connections available for the number of threads needing to use one. This results in threads having to wait until one is released from another thread. In the thread shown, it is waiting to get a read connection from the read pool.
TopLink connection pools are described in the docs at:
http://www.oracle.com/technology/products/ias/toplink/doc/1013/main/_html/srvclius002.htm#CHDJAECD
I'd recommend increasing the min/max number of connections to something that is appropriate to handle your peak load based on your applications usage paterns.
Best Regards,
Chris

WLS 10.3.0.0 Solaris SPARC and DBMS Oracle 10gR2 connection pooling issue

Hi all,
we are currently testing Weblogic Server 10.3.0.0 in order to migrate our production system from WLS 8.1 to it.
While testing the new setup, we encountered some strange behaviour of the connection pooling within WLS.
We configured a XA-Connection pool to our DB (Oracle 10gR2) by using
a) the Oracle XA-thin-driver delivered within WLS 10.3.0.0
and alternatively
b) the Oracle 11.2.0.2 OCI-driver of the Oracle 11g database client.
We´ve got the same issue with both variants. We defined an initial capacity of 5 connections and a maximum capacity of 30 connections.
Our application is running flawlessly using the connection pool, but the amount of active sessions between the application server and the database server is increasing rapidly and the maximum capacity is exceeded. We are seeing up to multiple hundreds of sessions from the application server to our database server. Obviously the connections aren´t cleaned up.
We are using the following settings for the JDBC-Connection:
initial capacity = 5
max. capacity = 30
Capacity increment = 1
Statement cache type = LRU
Statement cache size = 10
Test connections on reserve = true
Test frequency = 120
Test table name = "sql select 1 from dual"
seconds to trust an idle pool connection = 10
shrink frequency = 0
connecttion creation retry frequency = 120
login delay = 0
incative connection timeout = 10
max. waiting for connection = 2147483647
connection reserve timeout= = -1
Ignare in-use connections = true
pinned-to-thread = false
remoce infected connections enabled = true
Does anyone have an idea how to track/solve this issue?
Kind regards
Marc

Hi Joe,
we´ve tested with the thin driver using an initial capacity of 5 and a maximum capacity of 15. During our tests (in a very short time period) the maximum capacity has not been exceeded. But we saw some exceptions in the managed server logfile which made us curious.
When these exceptions are occuring, a new connection to the database server is established. We are seeing for a short time a total count of 6 connections which is immediately decreasing to the initial capacity of 5. We will do some further testing over the next hours and monitor the connection usage.
The connection we are dealing with is the one called "ZDB2".
This is an excerpt of the logfile:

Pointbase Server, Connection Pool Issue

Hi All,
          I have set up a cluster containing two nodes - one local and other
          remote machine.
          I have extended my domain to include the Integration and Workshop
          extensions, as my application needs them. I have also configured the
          Node Manager to start the remote server and also setup the workshop
          database on my machine.
          I have set the classpath in the Node Manager to contain the jars -
          E:\bea_sp5\weblogic81\server\lib\weblogic.jar;E:\bea_sp5\weblogic81\common\eval\pointbase\lib\pbserver44.jar;

          Why do you think this error is occuring? Any other setting needs to be
          done to overcome this problem ?
          Thanks in advance,
          Sandeep

Please verify following
1) have you defined jndi name for database correctly ??
2) Have you added sqljdbc jar file in soa suite server?
3) How much time it takes when you execute same query in JDev ?
4) If you think configuration is issue, please verify the Jdev conn details @ http://soasphere.blogspot.com/2008/11/connecting-sql-server-from-jdeveloper.html and soa suite server side required settings @ Deploy error because of sql server database adapter

SP3 conection pool issue with Oracle thin driver

Hello
I have a single instance of iAS runnin a single instance of kjs on
Solaris8. There is a data source configured to use oracle thin drivers
as opposed to Netscape Type 2 driver for Oracle as per Tech support's
suggestion:
The pool setting are as folows:
Max Pool Size : 20
Steady Pool size : 10:
The symptoms that I am seeing is that if (repeatedly) in a JSP I have
code to lookup a data source and obtain a connection and perform some
useful work on the DB, the pool seems to grow to more than 20 connection
- which is the max pool size. I wated this happen until we burtn ~100
connetions to the database:
The SQL I am using to determine connections on the database is as
follows:
select machine, osuser, count(*) "All" from v$session group by
machine,osuser;
Global Txn are disable on the app server.
Running out of ideas, any help will be greatly appreciated.
Thanks
Immanuel

Immanuel,
Connection Pooling in iPlanet is poorly documented and, in my experience,
somewhat buggy.
On your specific problem, the documentation implies that Max Pool Size is
the
maximum number of connections, and MaxWait is a maximum time they would wait
to get a connection. It doesn't explain as far as I can see what happens if
that
time expires -- an exception (which one), or does it exceed the limit and
return a new connection?
To resolve this problem I'd suggest you write up a simple, repeatable test
case and submit
it as a bug report to get resolution on the issue.
My experiences are:
* SP2 doesn't check for bad connections, and will recycle them in the pool
as though they
are valid. We worked with support to get a patch developed that fixes this.
The release notes
for SP3 imply this problem is fixed (534541 JDBC ), but I'm somewhat
doubtful of that claim.
The patch we have required us to create a table with specific data in it
which they test with a query
prior to retrieving a connection from the pool. I don't see anything in the
SP3 docs instructing a user
to do this, so I question whether the bug fix is in the product but the
enabling steps are not documented,
or not even in the release.
* I have a current dialog going with support about a kjs crash that happens
after a large
number of connections are allocated and then released. The kjs log
indicates that the process
detects some problem and aborts.
Good luck, and let us know when you get a resolution to the problem.

useful work on the DB, the pool seems to grow to more than 20 connection
- which is the max pool size. I wated this happen until we burtn ~100
connetions to the database:
The SQL I am using to determine connections on the database is as
follows:
select machine, osuser, count(*) "All" from v$session group by
machine,osuser;
Global Txn are disable on the app server.
Running out of ideas, any help will be greatly appreciated.
Thanks

Pooling Issues with Root AM approach

Hello All,
My JDeveloper Version : 11.1.2.3.0
Weblogic Server Version : 10.3.5
Database Version Oracle 11G
i am working on a application which about to go live and during load tests we have identified database connection usage is more oracle support suggested us to go with single root application module approach so we have migrated application to use only one application module and all the other modules we have nested in this am. this approach is good and db connections are also limited to number of users and business we haven't found any issues with this migration. but we are facing below errors in server logs.
the observations i have made during load test with 30 users :
1)datasource connection pool size is 30
2)2GB Ram
3)linux server.
if 30 users are working with the system concurrently jdbc connections in weblogic console it was showing under Active Connections High Count 13
and sessions it was showing 30
if 31 + session are getting launched i am getting below exception i am facing below issue in jdeveloper console and in server logs often.
please suggest me some inputs to resolve this error.
one more notification from dms/Spy i observed is instancesCheckedOutFailed is getting increased 31+ session onwards.

Nested AMs do not have their own DB connection and a transaction object but they use (i.e. share) the connection and the transaction object of the root AM. When you commit/rollback a nested AM instance, you in fact commit/rollback the root AM together with all its nested AM instances.
If you want to commit the regions separately, you must not use nested AMs (in one and same root AM) but separate root AMs instead.

Windows Service Enterprise Library Data Access Application Blocks Connection Pooling Issue

Hello,
We are developing a windows service using c# .net v 4.5.1 which communicates with SQL database (SQL 2008 R2 x64), communication with SQL server is done using Enterprise Library data access block v 6, The windows service does a file copy process in bulk &
updates the database about the status of file copy, it is observed that as soon as we start the service the number of connections get max out & we start receiving a "Timeout expired. The timeout period elapsed prior to obtaining a connection
from the pool. This may have occurred because all pooled connections were in use and max pool size was reached."
This issue is only observed when we run the code logic by deploying it as a windows service, When we run the exactly same code as a standalone exe (right click -> run as administrator) / non windows service, the connections on database are not exceeded
& we do not receive the above mentioned error.
The code block which makes calls to the database is under the c# "using" statement, hence connection pooling should be handled by default.
Could you please recommend any suggestions on areas which I might have missed on to investigate this issue.
Thanks in advance.

Hi
The issue got resolved after refresh the SCOM Data base access service account in SQL 2012.
Unable to launch the operations manager 2012 R2 console after extended the C drive of the SQl server ,getting error "The Data
Access service is either not

Got to your SQL server -->databases-operationsmanager--security-users--locate the daa service account and refresh.issue fixed and am able to luanch.

Connection Pool problems with Weblogic SP4 & Toplink 9.0.4.5

Hi,
i have updated my Weblogic 8.1 from SP2 to SP4. Since that I always get the following exception:
Hi,
i have updated my Weblogic 8.1 from SP2 to Sp4. Since that I always get the following exception:
Exception [TOPLINK-4002] (TopLink (WLS CMP) - 10g (9.0.4.5) (Build 040930)): oracle.toplink.exceptions.DatabaseException
Exception-Beschreibung: java.sql.SQLException: Pool connect failed : javax.security.auth.login.FailedLoginException: [Securit
y:090304]Authentication Failed: User javax.security.auth.login.LoginException: [Security:090301]Password Not Supplied
This exception is thrown when the StartUp-Servlet tries the first time to establish an connection to my Connection Pool. The connection pool itself has been tested in the Weblogic-console and works fine.
Thanks for help.

Sebastian,
9.0.4.5 is the version with fixes to address changes made by BEA in SP4 so this should work. I do recall some issue with our login configuration and the data source.
Is the user-name specified in either your sessions configuration of project XML without a password. This may be an issue where if part of the credentials are supplied it is asking for the rest.
