RE: Conections Opened

[Chen, Tim]

1) have you closed your connections in a finally block? opening a new connection for each call is sever.. it *should* be getting some connections from the pool.

2) have you tried playing with maxRequests in <settings>?

3) how many connections before the error msg? (have a dba check for you if you aren't sure) is it possible that you just have the limit set too high?

4) if all else fails use a JNDI connection and setup the connection pool within your container.

I still have this problem. Every single call I made a new connection is opened. The DaoManager is started just one time. And the connection remain opened for a  long time until oracle returns a error of max number of connections opened.

Any ideas to solve this problem?

tks!

When you do first call DBCP creates minimum number of connections

and uses these connections until all connections are busy(active/running) and new connection is created.

 

If you compare first call and second, the first one should take much time then second one.

 

But if "every call I do a new connection is created" that only can mean that your calls are too fast and DBCP

can't create connections automatically and creates during call.

 

Best,

Hi,

I have configured the maxActive connection with 10 but every call I do a new connection is created.

 <transactionManager type="JDBC">
    <dataSource type="DBCP">
      <property value="${database_driver}" name=" JDBC.Driver"/>
      <property value="${database_url}" name="JDBC.ConnectionURL"/>
      <property value="${database_user}" name="JDBC.Username"/>
      <property value="${database_password}" name=" JDBC.Password"/>
      <property value="10" name="Pool.MaximumActiveConnections"/>
      <property value="5" name="Pool.MaximumIdleConnections"/>
      <property value="6000" name=" Pool.MaximumWait"/>
    </dataSource>
  </transactionManager>

This is my SQL-map-config like. How do I limit the number of opened connections?

tks!

Hi,

How many connections are opened by Ibatis to make a simple query?

In my sql-map-config, using SimpleDataSource (pool), the maxnumber of connection are like this:
<property value="1" name=" Pool.MaximumActiveConnections"/>
<property value="1" name="Pool.MaximumIdleConnections"/>
But Ibatis open 4 connections at least.

Cheers!
