Class SecureAdminBootstrapHelper

java.lang.Object

com.sun.enterprise.v3.admin.cluster.SecureAdminBootstrapHelper

public abstract class SecureAdminBootstrapHelper
extends Object

Bootstraps the secure admin-related files, either over ssh (copying files from the current runtime environment to the remote system via secure ftp) or locally (using more straightforward file-copying).

getRemoteHelper

public static SecureAdminBootstrapHelper getRemoteHelper(org.glassfish.hk2.api.ServiceLocator habitat,
                                                         File DASInstanceDir,
                                                         String remoteNodeDir,
                                                         String instance,
                                                         Node node,
                                                         Logger logger)
                                                  throws SecureAdminBootstrapHelper.BootstrapException

Creates a new helper for delivering files needed for secure admin to the remote instance.

Parameters:

habitat - hk2 habitat

DASInstanceDir - directory of the local instance - source for the required files

remoteNodeDir - directory of the remote node on the remote system

instance - name of the instance on the remote node to bootstrap

node - Node from the domain configuration for the target node

logger - Logger to use

Returns:

the remote helper

Throws:

SecureAdminBootstrapHelper.BootstrapException

getLocalHelper

public static SecureAdminBootstrapHelper getLocalHelper(File existingInstanceDir,
                                                        File newInstanceDir)

Creates a new helper for delivering files needed for secure admin to the local instance (local meaning on the same node as the DAS).

Parameters:

existingInstanceDir - directory of an existing instance (typically the DAS) from where the files can be copied

newInstanceDir - directory of the new instance to where the files will be copied

Returns:

the local helper

mkdirs

protected abstract void mkdirs(String dirURI)
                        throws IOException

Cleans up any allocated resources.

Throws:

IOException

close

protected abstract void close()

copyBootstrapFiles

protected abstract void copyBootstrapFiles()
                                    throws FileNotFoundException,
                                           IOException

Copies the bootstrap files from their origin to their destination.

Concrete subclasses implement this differently, depending on exactly how they actually transfer the files.

Throws:

FileNotFoundException

IOException

backdateInstanceDomainXML

protected abstract void backdateInstanceDomainXML()
                                           throws SecureAdminBootstrapHelper.BootstrapException

Adjusts the date on the new instance's domain.xml so it looks older than the original one on the DAS.

We have copied the domain.xml and a small number of other files to the instance, but not all the files needed for the instance to be fully sync-ed. The sync logic decides if an instance is up-to-date by comparing the timestamp of the instance's domain.xml with that of the DAS. If those timestamps match then the sync logic judges the instance to be up-to-date. When we copy the DAS domain.xml to the instance to deliver the secure admin configuration (so the start-local-instance command and the instance will know how to connect to the DAS) it is left with the same timestamp as the DAS copy. To make sure sync works when start-local-instance runs, we backdate the instance's copy of domain.xml.

Throws:

SecureAdminBootstrapHelper.BootstrapException

bootstrapInstance

public void bootstrapInstance()
                       throws SecureAdminBootstrapHelper.BootstrapException

Bootstraps the instance for remote admin.

Throws:

SecureAdminBootstrapHelper.BootstrapException
