Method Detail

initServerRegion

public static void initServerRegion()

Initializes the test region in the cache server VM according to the configurations in ConfigPrms.

See Also:

BridgeHelper.startBridgeServer(java.lang.String)

initEdgeRegion

public static void initEdgeRegion()

A Hydra INIT task that initialize the test region in an edge client according to the configurations in ConfigPrms.

acquireThreadLocalConnection

public static void acquireThreadLocalConnection()

A Hydra INIT task that sets the threadlocal connection of this thread. This is used to create all connections up from to fix bug 39481 for membership tests.

clearMembershipCounters

public static void clearMembershipCounters()

A Hydra INIT task that zeros out the MembershipListener counters after the servers & clients come up (the first time).

See Also:

BBoard.expectedServerJoinedEvents

getNumClients

public static int getNumClients()

startSnapshot

public static boolean startSnapshot()

Begin a JProbe snapshot

endSnapshot

public static boolean endSnapshot()

End a JProbe snapshot

doGetBatch

public static void doGetBatch()

Performs a bunch of gets on the hierarchical cache.

initBlackboard

public static boolean initBlackboard()

A STARTTASK that initializes the blackboard to keep track of the last time something was killed.

Returns:

Whether or not this task initialized the blackboard

killSomething

public static void killSomething()
                          throws ClientVmNotFoundException

A Hydra TASK that chooses a test component (either randomly or {@linkplain HctPrms#toggleKill alternately) such as a cache server or the "database" that it accesses and kills it. Checks to make sure that the bridge loader (edge client) discovers that the cache server has been killed.

Throws:

ClientVmNotFoundException

stopServers

public static void stopServers()
                        throws ClientVmNotFoundException

Throws:

ClientVmNotFoundException

restartComponent

public static void restartComponent(String comp,
                                    BridgeHelper.Endpoint endpoint)
                             throws ClientVmNotFoundException

Throws:

ClientVmNotFoundException

recycleClientConnection

public static void recycleClientConnection()

Hydra TASK to cause client to recycle connection to the distributed system (should appear as memberLeft & memberJoined events to the BridgeMembershipListener

See Also:

BBoard.expectedClientDeparted, BBoard.expectedClientJoined

killClientVm

public static void killClientVm()
                         throws ClientVmNotFoundException

Hydra CLOSETASK to cause client to kill itself immediately with a mean kill. These should appear as memberCrashed events BridgeClientListener Hydra doesn't permit us to kill all clientVms, so we must leave one clientVM behind.

Throws:

ClientVmNotFoundException

See Also:

BBoard.expectedClientCrashedEvents

validateMembershipEvents

public static void validateMembershipEvents()

A Hydra CLOSETASK to validate membershipEvents (expected vs. actual)

See Also:

BBoard.expectedServerCrashedEvents, BBoard.actualServerCrashedEvents, BBoard.expectedServerDepartedEvents, BBoard.actualServerDepartedEvents, BBoard.expectedServerJoinedEvents, BBoard.actualServerJoinedEvents, BBoard.expectedClientCrashedEvents, BBoard.actualClientCrashedEvents, BBoard.expectedClientDepartedEvents, BBoard.actualClientDepartedEvents, BBoard.expectedClientJoinedEvents, BBoard.actualClientJoinedEvents

reportAverages

public static void reportAverages()

A Hydra ENDTASK that prints out mean values for loadTime/loadsCompleted and getTime/gets on edge and server

getStackTrace

public static String getStackTrace(Throwable aThrowable)
