Closing conection from pool in runtime oracle-data-source

I have legacy web application. Witch uses jdbcTemplate to execute stored procedures from DB (Oracle), procedures located at packages. Problem is, when database developers compiles that packages im getting Expceptions sometihng like existing state of packages been changed (ora 4061). and they does that 1 or 2 times per week. Then i have to restart application to restart pool. app uses OracleDataSource. i can't change anything at that db but can change pool manager. so the question is. is it possible to close that connection? not just return to pool. and get new connection(from pool) if that Exception apears? thanks !!
people sugested to re-execute that stored procedure when that error apears. It doest worked.

Abnormal Behavior of Apache ActiveMQ on Multiple Consumer

I am using Jboss-fuse-6.3, with external Apache-activemq-5.15.2.
I have bind 50 consumers on a queue, and on Active MQ portal in "Active Consumers" page, I have noticed that all 50 consumers are bind but message distribution on queues are not the same.
Screen shot is attached. On session id "1" En-queued message count is around 1010 but on other consumer sessions En-queued messages are only 10.
Im en-queuing messages from Apache Camel Route. Below is my Blueprint xml (Am i doing some thing wrong)
<bean class="org.apache.activemq.spring.ActiveMQConnectionFactory" id="connectionFactory">
<property name="brokerURL" value="tcp://localhost:61616"/>
<property name="userName" value="admin"/>
<property name="password" value="admin"/>
<property name="trustAllPackages" value="true"/>
</bean>
<bean class="org.apache.camel.component.jms.JmsConfiguration" id="jmsConfig">
<property name="connectionFactory" ref="connectionFactory"/>
</bean>
<bean class="org.apache.activemq.camel.component.ActiveMQComponent" id="activemq">
<property name="configuration" ref="jmsConfig"/>
</bean>
<bean class="org.apache.activemq.spring.ActiveMQConnectionFactory" id="connectionFactory">
<property name="brokerURL" value="tcp://localhost:61616"/>
<property name="userName" value="admin"/>
<property name="password" value="admin"/>
<property name="trustAllPackages" value="true"/>
</bean>
<bean class="org.apache.camel.component.jms.JmsConfiguration" id="jmsConfig">
<property name="connectionFactory" ref="connectionFactory"/>
</bean>
<bean class="org.apache.activemq.camel.component.ActiveMQComponent" id="activemq">
<property name="configuration" ref="jmsConfig"/>
</bean>
<!-- ENQUEUEING MESSAGES -->
<to pattern="InOnly" uri="activemq:queue:MyQueue"/>
<!-- DEQUEUEING MESSAGES -->
<fromuri="activemq:queue:MyQueue?concurrentConsumers=50"/>

This appears to be normal prefetching behavior on the part of the JMS client. If you want competing consumers with fair dispatching then you need to lower the prefetch level as the first consumer that connects will often get a higher number of message dispatched to it because the default prefetch is 1000 for a Queue consumer.
Read more about ActiveMQ consumer prefetch here.

ActiveMQ: How to prevent message from going to "Dispatched Queue"

I'm using ActiveMQ with the spring framework.
I have two consumers setup in the jms container. When I send 4 message to the queue, and some of the message are transferred to the "Dispatched Queue", because it takes a long time to the consumer to process the message.
I'm trying to find the way to prevent the message from going to the "Dispatched Queue", that is, I want them to be available to any consumer that is ready to consume the message.
I tried to set pre-fetch to 0, but it doesn't seem to work at all.
<bean id="prefetchPolicy" class="org.apache.activemq.ActiveMQPrefetchPolicy">
<property name="queuePrefetch" value="0"/>
</bean>
<bean id="connectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<constructor-arg index="0" value="tcp://localhost:61616" />
<property name="prefetchPolicy" ref="prefetchPolicy"/>
</bean>
The following is the setup for my jms container:
<bean id="jmsContainer" class="org.springframework.jms.listener.DefaultMessageListenerContainer">
<property name="connectionFactory" ref="connectionFactory"/>
<property name="destination" ref="defaultDestination" />
<property name="messageListener" ref="messageListener" />
<property name="concurrentConsumers" value="2" />
</bean>

I found the problem. I had the same beans declared twice at two different places. The second bean that was loaded did not have pre-fetch set to 0 and therefore it didn't work out.
The above setup I posted works!
Thank you!

Spring config properties from database and properties

I asked a similar question, but based on the responses, I did a bad job describing what I am after. I have a spring 4 webapp that loads properties from a properties file. We consume those properties both via the "${proper.name"} expressions in spring, as well as by injecting a properties object into some of our classes.
We want to move most of the properties to a database table and make them reloadable. However, a few need to stay in local properties, potentially overriding the database setting. These should also be loaded dynamically after the app is running.
I know that once a particular bean is injected, it won't get reloaded, that doesn't concern me, it's up to that module to handle that. But I am having trouble getting the behavior I want. In particular, I have implemented an AbstractConfiguration from apache commons configuration to get the dual source and overriding I am after. But while it works for injecting the properties object, expressions loaded with "${prop.name}" don't work at all.
How can I get them to work? Did I override the wrong thing? Is it just some config detail?
<bean id="sysProperties" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject" ref="databaseConfigurator" />
<property name="targetMethod" value="getProperties"/>
</bean>
<bean id="databaseConfigurator" class="my.util.config.MyDatabaseConfigurator">
<property name="datasource" ref="dataSource" />
<property name="propertyFile" value="/WEB-INF/my.properties" />
<property name="applicationName" value="ThisApp" />
</bean>
<bean id="dbConfigFactory" class="org.apache.commons.configuration.ConfigurationConverter" factory-method="getProperties">
<constructor-arg ref="databaseConfigurator" />
</bean>

I haven't tested this, but I think it might work.
<bean id="sysProperties" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
<property name="targetObject" ref="databaseConfigurator" />
<property name="targetMethod" value="getProperties"/>
</bean>
<bean id="databaseConfigurator" class="my.util.config.MyDatabaseConfigurator">
<property name="datasource" ref="dataSource" />
<property name="propertyFile" value="/WEB-INF/my.properties" />
<property name="applicationName" value="ThisApp" />
</bean>
<bean name="PropertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="properties" ref="CommonsConfigurationFactoryBean"/>
</bean>
<bean name="CommonsConfigurationFactoryBean" class="org.springmodules.commons.configuration.CommonsConfigurationFactoryBean">
<constructor-arg ref="databaseConfigurator"/>

Unable to cache SFTP connection with Spring Integration

I need to transfer several small files via SFTP using spring integration, so I'd like to reuse a connection once established to avoid the overhead of creating a new one for every single message.
This is my current configuration:
<bean id="sftpTARGETSessionFactory" class="org.springframework.integration.sftp.session.DefaultSftpSessionFactory">
<constructor-arg name="isSharedSession" value="true"/>
<property name="host" value="${TARGET.push.host}"/>
<property name="user" value="${TARGET.push.user}"/>
<property name="privateKey" value="classpath:${TARGET.push.keyFile}"/>
<property name="privateKeyPassphrase" value="${TARGET.push.keyFilePass}"/>
</bean>
<bean id="cachingSessionFactory"
class="org.springframework.integration.file.remote.session.CachingSessionFactory">
<constructor-arg ref="sftpTARGETSessionFactory"/>
<property name="poolSize" value="2"/>
<property name="sessionWaitTimeout" value="2000"/>
</bean>
<int-sftp:outbound-channel-adapter
id="sftpTARGET"
session-factory="cachingSessionFactory"
channel="ftpTARGET.channel"
charset="UTF-8"
remote-file-separator="/"
remote-directory="${TARGET.push.path}"
mode="REPLACE"/>
Unfortunately this doesn't work as I expected: every message opens a new ssh connection.
any hint on what's going wrong?
Using spring-integration 4.1.6 here.
thanks!
