Method Detail

start

void start()

Starts the VM by invoking all the deployed services

shutdown

void shutdown(boolean now)

Shut down all services waiting for work to complete. Essential services will also be shutdown.

startDeployedService

void startDeployedService(ServiceComponentDefnID id)

Start the service identified by the ServiceComponentID If synch is true then wait for service to start before returning. Any exceptions will then be thrown to the caller. If synch is false then start service asynchronously.

startService

void startService(ServiceID serviceID)

Start a previously stopped service

stopService

void stopService(ServiceID id,
                 boolean now,
                 boolean shutdown)

Kill service once work is complete

checkService

void checkService(ServiceID serviceID)

Check the state of a service

setCurrentLogConfiguration

void setCurrentLogConfiguration(LogConfiguration logConfiguration)

Set the current log configuration.

getStartTime

long getStartTime()

Get the time the VM was initialized.

getAddress

java.net.InetAddress getAddress()

Get the address of the host this VM is running on.

getName

java.lang.String getName()

Get the name for this controller.

ping

void ping()

Method called from registries to determine if VMController is alive.

isShuttingDown

boolean isShuttingDown()

Returns true if system is being shutdown.

getVMStatistics

ProcessStatistics getVMStatistics()

Return information about VM. totalMemory, freeMemory, threadCount

dumpThreads

java.lang.String dumpThreads()

dumps stack trace to log file.

exportLogs

byte[] exportLogs()

Export the server logs to a byte[]. The bytes contain the contents of a .zip file containing the logs. This will export all logs on the host that contains this VMController.

Returns:

the logs, as a byte[].

Throws:

AdminException
