                        throws ManagementException

Description copied from interface: SystemRecoveryService

Recover all petals recoverable entities (component, shared lib and service assemblies)

Specified by:

recoverAllEntities in interface SystemRecoveryService

Throws:

ManagementException

recoverAllServiceAssembly

public void recoverAllServiceAssembly()
                               throws ManagementException

Throws:

ManagementException

recoverAllSharedLibrary

public void recoverAllSharedLibrary()
                             throws ManagementException

Throws:

ManagementException

moveUnknownDirsToLostPlusFoundDir

protected void moveUnknownDirsToLostPlusFoundDir(java.util.List<java.io.File> unknownDirs)

Move all unknown components from Petals repository to "lost+found" directory

Parameters:

unknownDirs - the List of unknown dirs that have to be moved.

recoverComponent

protected void recoverComponent(java.net.URL installUrl,
                                org.ow2.petals.jbi.descriptor.original.generated.Jbi descriptor,
                                java.lang.String installState,
                                java.lang.String lifecycleState,
                                java.lang.String compName)
                         throws ManagementException

Recover the given component. Recovering a component consist in redoing installation process of a component (see InstallationServiceMBean), calling the "install" method on the created Installer and putting the component in its previous state by calling "start" or/and "stop" on the created component lifecycle.

Parameters:

installationRoot -

installState -

lifecycleState -

Throws:

ManagementException

createRecoveryContext

protected Context createRecoveryContext(org.ow2.petals.jbi.descriptor.original.generated.Jbi descriptor,
                                        java.net.URL installUrl)

Create recovery context for component and shared libraries

Parameters:

descriptor -

installRoot -

Returns:

recoverServiceAssembly

protected void recoverServiceAssembly(java.net.URL installRoot,
                                      org.ow2.petals.jbi.descriptor.original.generated.Jbi descriptor,

                               throws ManagementException

Recover the given Service Assembly. Recovering a Service Assembly consist in redoing deployment process of a Service Assembly (see DeploymentServiceMBean) and putting the Service Assembly in its previous state by calling "start" or/and "stop" on the created component lifecycle.

Parameters:

installationRoot -

lifecycleState -

Throws:

ManagementException

createDeploymentContext
