      org.jboss.system.ServiceMBeanSupport
          org.jboss.resource.connectionmanager.JBossManagedConnectionPool

All Implemented Interfaces:

EventListener, javax.management.MBeanRegistration, javax.management.NotificationBroadcaster, javax.management.NotificationEmitter, javax.management.NotificationListener, JBossManagedConnectionPoolMBean, org.jboss.system.Service, org.jboss.system.ServiceMBean

public class JBossManagedConnectionPool
extends org.jboss.system.ServiceMBeanSupport
implements JBossManagedConnectionPoolMBean, javax.management.NotificationListener

The JBossManagedConnectionPool mbean configures and supplies pooling of JBossConnectionEventListeners to the BaseConnectionManager2 mbean.

It may be replaced by any mbean with a readable ManagedConnectionPool attribute of type ManagedConnectionPool. Normal pooling parameters are supplied, and the criteria to distinguish ManagedConnections is set in the Criteria attribute.

Constructor Detail

JBossManagedConnectionPool

public JBossManagedConnectionPool()

Method Detail

getManagedConnectionPool

public ManagedConnectionPool getManagedConnectionPool()

Description copied from interface: JBossManagedConnectionPoolMBean

ManagedConnectionPool is a read only attribute returning the pool set up by this mbean.

Specified by:

getManagedConnectionPool in interface JBossManagedConnectionPoolMBean

Returns:

the ManagedConnectionPool implementing the pool configured by this mbean.

getManagedConnectionFactoryName

public javax.management.ObjectName getManagedConnectionFactoryName()

Description copied from interface: JBossManagedConnectionPoolMBean

ManagedConnectionFactoryName holds the ObjectName of the mbean that represents the ManagedConnectionFactory. Normally this can be an embedded mbean in a depends element rather than a separate mbean reference.

Specified by:

getManagedConnectionFactoryName in interface JBossManagedConnectionPoolMBean

Returns:

the ManagedConnectionFactoryName value.

setManagedConnectionFactoryName

public void setManagedConnectionFactoryName(javax.management.ObjectName newManagedConnectionFactoryName)

Description copied from interface: JBossManagedConnectionPoolMBean

Set the ManagedConnectionFactoryName value.

Specified by:

setManagedConnectionFactoryName in interface JBossManagedConnectionPoolMBean

Parameters:

newManagedConnectionFactoryName - The new ManagedConnectionFactoryName value.

getAvailableConnectionCount

public long getAvailableConnectionCount()

Description copied from interface: JBossManagedConnectionPoolMBean

Get number of available free connections

Specified by:

getAvailableConnectionCount in interface JBossManagedConnectionPoolMBean

Returns:

number of available connections

getMaxConnectionsInUseCount

public long getMaxConnectionsInUseCount()

Specified by:

getMaxConnectionsInUseCount in interface JBossManagedConnectionPoolMBean

getInUseConnectionCount

public long getInUseConnectionCount()

Description copied from interface: JBossManagedConnectionPoolMBean

Get number of connections currently in use

Specified by:

getInUseConnectionCount in interface JBossManagedConnectionPoolMBean

Returns:

number of connections currently in use

getMinSize

public int getMinSize()

Description copied from interface: JBossManagedConnectionPoolMBean

The MinSize attribute indicates the minimum number of connections this pool should hold. These are not created until a Subject is known from a request for a connection. MinSize connections will be created for each sub-pool.

Specified by:

getMinSize in interface JBossManagedConnectionPoolMBean

Returns:

the MinSize value.

setMinSize

public void setMinSize(int newMinSize)

Description copied from interface: JBossManagedConnectionPoolMBean

Set the MinSize value.

Specified by:

setMinSize in interface JBossManagedConnectionPoolMBean

Parameters:

newMinSize - The new MinSize value.

getMaxSize

public int getMaxSize()

Description copied from interface: JBossManagedConnectionPoolMBean

The MaxSize attribute indicates the maximum number of connections for a pool. No more than MaxSize connections will be created in each sub-pool.

Specified by:

getMaxSize in interface JBossManagedConnectionPoolMBean

Returns:

the MaxSize value.

setMaxSize

public void setMaxSize(int newMaxSize)

Description copied from interface: JBossManagedConnectionPoolMBean

Set the MaxSize value.

Specified by:

setMaxSize in interface JBossManagedConnectionPoolMBean

Parameters:

newMaxSize - The new MaxSize value.

getBlockingTimeoutMillis

public int getBlockingTimeoutMillis()

Description copied from interface: JBossManagedConnectionPoolMBean

The BlockingTimeoutMillis attribute indicates the maximum time to block while waiting for a connection before throwing an exception. Note that this blocks only while waiting for a permit for a connection, and will never throw an exception if creating a new connection takes an inordinately long time.

Specified by:

getBlockingTimeoutMillis in interface JBossManagedConnectionPoolMBean

Returns:

the BlockingTimeout value.

setBlockingTimeoutMillis

public void setBlockingTimeoutMillis(int newBlockingTimeout)

Description copied from interface: JBossManagedConnectionPoolMBean

Set the BlockingTimeout value.

Specified by:

setBlockingTimeoutMillis in interface JBossManagedConnectionPoolMBean

Parameters:

newBlockingTimeout - The new BlockingTimeout value.

getIdleTimeoutMinutes

public long getIdleTimeoutMinutes()

Description copied from interface: JBossManagedConnectionPoolMBean

The IdleTimeoutMinutes attribute indicates the maximum time a connection may be idle before being closed. The actual maximum time depends also on the IdleRemover scan time, which is 1/2 the smallest IdleTimeout of any pool.

Specified by:

getIdleTimeoutMinutes in interface JBossManagedConnectionPoolMBean

Returns:

the IdleTimeoutMinutes value.

setIdleTimeoutMinutes

public void setIdleTimeoutMinutes(long newIdleTimeoutMinutes)

Description copied from interface: JBossManagedConnectionPoolMBean

Set the IdleTimeoutMinutes value.

Specified by:

setIdleTimeoutMinutes in interface JBossManagedConnectionPoolMBean

Parameters:

newIdleTimeoutMinutes - The new IdleTimeoutMinutes value.

getIdleTimeout

public long getIdleTimeout()

Get the IdleTimeout value.

Returns:

the IdleTimeout value.

setIdleTimeout

public void setIdleTimeout(long newIdleTimeout)

Set the IdleTimeout value.

Parameters:

newIdleTimeout - The new IdleTimeout value.

getCriteria

public String getCriteria()

Description copied from interface: JBossManagedConnectionPoolMBean

The Criteria attribute indicates if Subject (from security domain) or app supplied parameters (such as from getConnection(user, pw)) are used to distinguish connections in the pool. Choices are ByContainerAndApplication (use both), ByContainer (use Subject), ByApplication (use app supplied params only), ByNothing (all connections are equivalent, usually if adapter supports reauthentication)

Specified by:

getCriteria in interface JBossManagedConnectionPoolMBean

Returns:

the Criteria value.

setCriteria

public void setCriteria(String newCriteria)

Description copied from interface: JBossManagedConnectionPoolMBean

Set the Criteria value.
