Direct Known Subclasses:

LocalDomainCommand

public abstract class LocalServerCommand
extends CLICommand

A class that's supposed to capture all the behavior common to operation on a "local" server. It's getting fairly complicated thus the "section headers" comments. This class plays two roles,

• a place for putting common code - which are final methods. A parent class that is communicating with its own unknown sub-classes. These are non-final methods

  Method Summary

  protected boolean	checkForSpecialFiles() Override this method and return false to turn-off the file validation.
  protected HostAndPort	getAdminAddress() Returns the admin address of the local domain.
  protected HostAndPort	getAdminAddress(String serverName) Returns the admin address of a particular server.

  protected File	getMasterPasswordFile()
  protected int	getPrevPid()
  protected ServerDirs	getServerDirs()
  protected long	getUptime() Get uptime from the server.
  protected boolean	isRestartable() See if the server is restartable As of March 2011 -- this only returns false if a passwordfile argument was given when the server started -- but it is no longer available - i.e.
  protected boolean	isRunning() Is the server still running? This is only called when we're hanging around waiting for the server to die.
  protected boolean	isRunning(int port) convenience method for the local machine
  protected boolean	isRunning(String host, int port) There is sometimes a need for subclasses to know if a local domain is running.

  LocalServerCommand

  public LocalServerCommand()

  Method Detail

  checkForSpecialFiles

  protected boolean checkForSpecialFiles()

  Override this method and return false to turn-off the file validation. E.g. it demands that config/domain.xml be present. In special cases like Synchronization -- this is how you turn off the testing.

  Returns:

  true - do the checks, false - don't do the checks

  getAdminAddress

  protected final HostAndPort getAdminAddress()
                                       throws CommandException

  Returns the admin address of the local domain. Note that this method should be called only when you own the domain that is available on an accessible file system.

  Returns:

  HostAndPort object with admin server address

  Throws:

  CommandException - in case of parsing errors

  getAdminAddress

  protected final HostAndPort getAdminAddress(String serverName)
                                       throws CommandException

  Returns the admin address of a particular server. Note that this method should be called only when you own the server that is available on an accessible file system.

  Returns:

  HostAndPort object with admin server address

  Throws:

  CommandException - in case of parsing errors

  setServerDirs

  protected final void setServerDirs(ServerDirs sd)

  setLocalPassword

  protected final void setLocalPassword()

  unsetLocalPassword

  protected final void unsetLocalPassword()

  resetServerDirs

  protected final void resetServerDirs()
                                throws IOException

  Throws:

  IOException

  getServerDirs

  protected final ServerDirs getServerDirs()

  getDomainXml

  protected final File getDomainXml()

  readFromMasterPasswordFile

  protected final String readFromMasterPasswordFile()

  Checks if the create-domain was created using --savemasterpassword flag which obtains security by obfuscation! Returns null in case of failure of any kind.

  Returns:

  String representing the password from the JCEKS store named master-password in domain folder

  verifyMasterPassword

  protected final boolean verifyMasterPassword(String mpv)

  loadAndVerifyKeystore

  protected boolean loadAndVerifyKeystore(File jks,
                                          String mpv)

  getMasterPassword

  protected final String getMasterPassword()
                                    throws CommandException

  Get the master password, either from a password file or by asking the user.

  Throws:

  CommandException

  isThisServer

  protected final boolean isThisServer(File ourDir,
                                       String directoryKey)

  See if the server is alive and is the one at the specified directory.

  Returns:

  true if it's the DAS at this domain directory

  isRunning

  protected final boolean isRunning(String host,
                                    int port)

  There is sometimes a need for subclasses to know if a local domain is running. An example of such a command is change-master-password command. The stop-domain command also needs to know if a domain is running without having to provide user name and password on command line (this is the case when I own a domain that has non-default admin user and password) and want to stop it without providing it.

  In such cases, we need to know if the domain is running and this method provides a way to do that.

  Returns:

  boolean indicating whether the server is running

  isRunning

  protected final boolean isRunning(int port)

  convenience method for the local machine

  isRunning

  protected boolean isRunning()

  Is the server still running? This is only called when we're hanging around waiting for the server to die. Byron Nevins, Nov 7, 2010 - Check to see if the process itself is still running We use OS tools to figure this out. See ProcessUtils for details. Failover to the JPS check if necessary

  waitForRestart

  protected final void waitForRestart(File pwFile,
                                      long oldTimeStamp,
                                      long uptimeOldServer)
                               throws CommandException

  Throws:

  CommandException

  getPrevPid

  protected final int getPrevPid()

  getUptime

  protected final long getUptime()
                          throws CommandException

  Get uptime from the server.

  Throws:

  CommandException

  isRestartable

  protected final boolean isRestartable()
                                 throws CommandException

  See if the server is restartable As of March 2011 -- this only returns false if a passwordfile argument was given when the server started -- but it is no longer available - i.e. the user deleted it or made it unreadable.

  Throws:

  CommandException

  getMasterPasswordFile

  protected File getMasterPasswordFile()
