Toplink Mysql Connection pool issues

I am frequently seeing threads in wait state on toplink connection pool, I have given the stack trace below, anyone has any ideas as to what is happening? is it
related to connection timeout? or other causes...

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

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.

J2EE mysql connection pool

Hello,
I am trying to create a mysql connection pool using the admin console. The mysql JDBC driver is located in <install_dir>/domains/domain1/lib/ext.
For Datasource Classname I use com.mysql.jdbc.jdbc2.optional.MysqlDataSource
A ping results in:
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Connection could not be allocated because: null, message from server: "Host 'localhost.localdomain' is not allowed to connect to this MySQL server"
When changing the URL property to localhost a ping results in:
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Connection object cannot be null
Any ideas about what goes wrong?
Thanks...

I did a simple php test:
<?php
mysql_connect("localhost.localdomain", "user", "pass") or die(mysql_error());
echo "Connected to MySQL<br />";
?>
This results in:
Warning: mysql_connect(): Host 'localhost.localdomain' is not allowed to connect to this MySQL server in /var/www/mathesis/mambo/mysql.php on line 2
Host 'localhost.localdomain' is not allowed to connect to this MySQL server
<?php
mysql_connect("localhost", "user", "pass") or die(mysql_error());
echo "Connected to MySQL<br />";
?>
results in: Connected to MySQL
So I see two possible solutions:
1) Make the appserver use localhost instead of localhost.localdomain (specifying localhost as property doesn't work!).
2) Make MySQL accept localhost.localdomain connections.
For both possible solutions I'm searching for answers...

Monitoring of topLink internal connections pool

we wish to monitoring use of Toplink internal connections pool : numbers maximum used, a minimum number used.
we know to do it with the external pool (OracleAS) but not with the internal pool.
Regards

The only way to get this information is through API calls. If you have a Server (oracle.toplink.threetier) you can ask the read and default (write) connection pools.
        // Display Read Connection pool info
        System.out.println("READ Available: " +
                           server.getReadConnectionPool().getConnectionsAvailable().size());
        System.out.println("READ Minimum: " +
                           server.getReadConnectionPool().getMinNumberOfConnections());
        System.out.println("READ Maximum: " +
                           server.getReadConnectionPool().getMaxNumberOfConnections());
        // Display Write Connection pool info
        System.out.println("WRITE Available: " +
                           server.getDefaultConnectionPool().getConnectionsAvailable().size());
        System.out.println("WRITE Minimum: " +
                           server.getDefaultConnectionPool().getMinNumberOfConnections());
        System.out.println("WRITE Maximum: " +
                           server.getDefaultConnectionPool().getMaxNumberOfConnections());Doug

Connection Pooling Issue

Hi,
We have a performance issue in one of our Web applications.
Our environment is Servlets running on IPlanet server / calling stored procedures in Oracle 8.1.6 database.
The problem we are having is when we have more than a 100 concurrent users accessing the web application,
the performance is very (pathetically) slow and users get time-out errors.
But, the same application runs just fine when we have lesser concurrent users (about 50) doing the
exact same thing.
We have the sessions param in the database set at 600 and the connection pool max connections as 400.
Based on the monitoring we have done, we can see that some many connections are Inactive but not
being re-used by the connection pool. We have checked the servlet code and we close the connection
immediately after the stored procedure call is completed.
Please let me know if you have faced similar problems and ideas how to fix this issue.
Thanks
Balaji

The internal TopLink connection pool does not automatically reconnect dead connections.
You can use an ExceptionHandler in TopLink to do this. Refer to the documentation for more information on TopLink ExceptionHandlers, I believe that there is an example of this. There are some old posts in the forums explaining how to do this if you try searching.
You could also use a J2EE server's connection pool which may support this.

MySQL connection pooling (tomcat) problem

Hi all i just started learning servlets and i want to make a program in order to understand database connection pooling in tomcat.My problem is that when i run the servlet i created i get this error :
java.lang.NullPointerException org.DB.TestDB2.doGet(TestDB2.java:105) javax.servlet.http.HttpServlet.service(HttpServlet.java:690) javax.servlet.http.HttpServlet.service(HttpServlet.java:803) org.netbeans.modules.web.monitor.server.MonitorFilter.doFilter(MonitorFilter.java:390)
And that from tomcat log from netbeans :
org.apache.tomcat.dbcp.dbcp.SQLNestedException: Cannot create JDBC driver of class '' for connect URL 'null'
.I configured tomcat server.xml file like this :
<Context path="/DBTest" docBase="DBTest"         debug="5" reloadable="true" crossContext="true">   <Resource name="jdbc/phonebook_db" auth="Container" type="javax.sql.DataSource"               maxActive="100" maxIdle="30" maxWait="10000"               username="*******" password="********" removeAbandoned="true"               removeAbandonedTimeout="120" driverClassName="com.mysql.jdbc.Driver"               url="jdbc:mysql://localhost:3306/test_phonebook_db?autoReconnect=true"/> </Context>
This is the resource reference i have in my web app web.xml file :
<resource-ref>       <description>DB Connection</description>       <res-ref-name>jdbc/phonebook_db</res-ref-name>       <res-type>javax.sql.DataSource</res-type>       <res-auth>Container</res-auth>   </resource-ref>
And this is my servlet class :

Thank you for your answer.Yes my servlet class is something more worse than horrible(i don't use the database connection correct i don't use the MVC pattern i use out.println() ) but i just tried to take a ready example and try to understand .So i write this servlet myself as a starting point :
package org.DB;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.*;
import java.sql.*;
public class DBServlet extends HttpServlet {
    private Connection conn ;
    private Statement stat ;
    private ResultSet rs ;
    private int counter;
    String driver = "com.mysql.jdbc.Driver";
    String dbURL = "jdbc:mysql://localhost:3306/phonebookdb?user=**********&password=************";
    @Override
public void init() {
     try {
            Class.forName(driver).newInstance();
            conn = DriverManager.getConnection(dbURL);
     }catch(Exception e) {
              e.printStackTrace();
              System.err.print("Unable to make connection ");
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
            out.println("<html>");
            out.println("<head>");
            out.println("<title>Servlet DBServlet</title>");
            out.println("</head>");
            out.println("<body>");
            out.println("<h1>Servlet DBServlet at " + request.getContextPath () + "</h1>");
            out.println("<br /><br /><br />");
            if(conn!=null)
                out.println("conn object : "+conn);
            out.println("</body>");
            out.println("</html>");
        } catch(Exception sq) {
            System.out.println("Exception" + sq.getMessage());
            out.close();
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
     public void destroy() {
     try {
         conn.close();
     } catch (SQLException sqle) {
         sqle.printStackTrace();
    @Override
    public String getServletInfo() {
        return "A Simple Servlet";
}And it work for now.

MySQL - Connection Pooling - Driver?

Hi there!
I am looking for a JDBC 2.0 compatible driver to use with MySQL. I would like to use connection pooling in a webapplication (JSP:s and Servlets) but I have just found out that the driver I usually use mmmysql do not support connection pooling. Hence, my question: Where can I find a driver to use with MySQL with support for Connection Pooling?
bw

have you tried resin..
http://www.caucho.com/projects/jdbc-mysql/index.xtp
i haven't checked it yet but it could be an option
i'm currently using mmmysql driver also...I tried that driver and when I had more than one statement open at the same time, it gave me garbage results and then threw an exception. So I'm using the mmmysql driver too.

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:

Error using mySQL connection Pool

I see the following error when my application uses the connection pool - can anyone explain this ?
INFO: CORE3282: stdout: =======================>ERROR :com.sun.enterprise.repository.J2EEResourceException

Hi,
You have used dataSourceName property while creating a connection pool.This property is not required to be set while creating a connection pool for MySql
Use the following properties:
<property name="serverName" value="<name of server>"
<property name="port" value="<port number>"
<property name="DatabaseName" value="<your db name>"
<property name="User" value="<user name>"
<property name="Password" value="<passwd>"
Get back in case of any issues

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

MySQL Connection Pooling

Our application uses castor and MySQL. When running in WebLogic, what is the best (portability is key) way to provide a connection pool to my application?
Thanks in advance!
George Redens
Sr. Developer
CertAlert Software, Inc

Do you write the code that obtains your JDBC
connections, or is it embedded in Castor?
If you can write the code that obtains your
jdbc connections, then the standard pool
documentation is what you should follow.
If you do not have direct access to the
code creating your JDBC connections,
tell us how you specify them, and maybe you
can use our pools, and maybe not.

MySQL connection pooling guidelines

Dear tribe,
Although using autoReconnect=true in my pool definition, I keep running out of connections...
This morning changed to autoReconnectForPools=true flag (along with autoReconnect) and upgraded to Connector/J 3.0.11.
While I'm waiting to see if this will work out, can someone please point to some guidelines on setting up connection pools specifically for MySQL and AppServer7 or post a working configuration (jar versions, web.xml fragment etc)?
Thanks,
Manos

My initial configuration was exactly that but was failing to connect after leaving the applicatin running for 8 hours. I then added autoReconnect=true and autoReconnectForPools=true. But after leaving the application running without any requests to it, this morning i tried to load a page and got closed connection errors again...

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.

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

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

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
