oracle.toplink.remote
Class CacheSynchronizationManager

java.lang.Object
oracle.toplink.remote.CacheSynchronizationManager

Deprecated. since OracleAS TopLink 10g (10.1.3). This class is replaced by CommandManager

public class CacheSynchronizationManager

extends java.lang.Object

Purpose: Allow for a cluster or group of application servers or TopLink sessions to distributely broadcast cache changes to the other servers to synchronize the state of the cache object.

Description: This allows for applications that require multiple application servers to decrease the possibilty of stale data in the TopLink cache.

Constructor Detail

CacheSynchronizationManager

public CacheSynchronizationManager()

Deprecated.

PUBLIC: Creates a CacheSynchronizationManager.

CacheSynchronizationManager

public CacheSynchronizationManager(java.lang.Class clusteringServiceClassType)

Deprecated.

PUBLIC: Creates a CacheSynchronizationManager.

Parameters:

clusteringServiceClassType - the class that will be instantiated to connect all nodes

CacheSynchronizationManager

public CacheSynchronizationManager(java.lang.Object controller)

Deprecated. As of version 4.0

PUBLIC: Creates a CacheSynchronizationManager.

Parameters:

controller - This must be a globally available RemoteSessionController

Method Detail

initialize

public void initialize()

Deprecated.

ADVANCED: THis method is called during the Login of the session to set up the synchronization service

addRemoteConnection

public void addRemoteConnection(RemoteConnection connection)

Deprecated.

PUBLIC: Add a remote Connection for cache synchronisation. This connection will be updated with the changes that occur to this session's cache.

connectToAllRemoteServers

public void connectToAllRemoteServers()

Deprecated.

PUBLIC: Connect to all known servers, that have been specified through addRemoteConnections. This notifies the other servers that this server is alive and desires it's cache to be synchronized with their caches. The other server will then send all committed changes back through the remote connection to this server. Note: any errors that occur will be ignored and this will continue to connect to the other servers, these errors will be logged to the session's log.

getRemoteConnections

public java.util.Hashtable getRemoteConnections()

Deprecated.

PUBLIC: Returns the list of remote connections for cache synchronisation.

getSessionRemoteController

public java.lang.Object getSessionRemoteController()

Deprecated. Since 4.0

ADVANCED: Returns the remoteSession controller dispatcher that this session has made available for synchronization.

getSessionRemoteConnection

public RemoteConnection getSessionRemoteConnection()

Deprecated.

ADVANCED: Returns the remoteSession controller dispatcher that this session has made available for synchronization.

removeAllRemoteConnections

public void removeAllRemoteConnections()

Deprecated.

PUBLIC: Remove all remote connections for cache synchronisation. All remote connections will no longer be updated with the changes

removeRemoteConnection

public void removeRemoteConnection(RemoteConnection connection)

Deprecated.

PUBLIC: Remove a remote connection for cache synchronisation. This connection will no longer be updated with the changes.

setIsAsynchronous

public void setIsAsynchronous(boolean isAsynchronous)

Deprecated.

ADVANCED: This method is used to set if the propagation of the change sets should be asynchronous. This means that the client will return from the commit before the changes may have been propigated.

isAsynchronous

public boolean isAsynchronous()

Deprecated.

PUBLIC: Return whether the propagation of the change sets should be asynchronous. Asynchronous propagation means that the client will return from the commit before the changes may have been propigated.

Returns:

boolean

setSessionRemoteController

public void setSessionRemoteController(java.lang.Object remoteSessionController)

Deprecated. As of version 4.0

ADVANCED: Sets the remoteSession controller dispatcher that this session has made available for synchronization.

setSessionRemoteConnection

public void setSessionRemoteConnection(RemoteConnection remoteSessionConnection)

Deprecated.

ADVANCED: Sets the remoteSession connection that this session will make available for synchronization. Other session will communicate with this session through this connection

setShouldRemoveConnectionOnError

public void setShouldRemoveConnectionOnError(boolean shouldRemoveConnectionOnError)

Deprecated.

PUBLIC: Allow whether connections to remote servers should be disconnected when an error occurs

shouldRemoveConnectionOnError

public boolean shouldRemoveConnectionOnError()

Deprecated.

PUBLIC: Return whether connections to remote servers should be disconnected when an error occurs

setClusteringService

public void setClusteringService(AbstractClusteringService clusteringService)

Deprecated.

ADVANCED: Use this method to set the clusteringService used to synchronize the distributed sessions The class supplied must subclass AbstractClusteringService

Parameters:

clusteringService -

setClusteringServiceClassType

public void setClusteringServiceClassType(java.lang.Class clusteringServiceClassType)

Deprecated.

ADVANCED: Use this method to set the class type to be used to synchronize the distributed sessions The class supplied must subclass AbstractClusteringService

Parameters:

clusteringServiceClassType -

getLocalHostURL

public java.lang.String getLocalHostURL()

Deprecated. since 4.5 now set on ClusteringService

This method will return the Host URL of the JNDI service for this node

setLocalHostURL

public void setLocalHostURL(java.lang.String localHostURL)

Deprecated. since 4.5 now set on ClusteringService

This method will set the Host address of the JNDI service
