Method Detail

HydraTask_createLocator

public static void HydraTask_createLocator()

Create locator task

HydraTask_startLocatorAndDS

public static void HydraTask_startLocatorAndDS()

Start locator task

HydraTask_initializeRegions

public static void HydraTask_initializeRegions()

Creates and initializes a server or peer.

HydraTask_offHeapCeilingTest

public static void HydraTask_offHeapCeilingTest()

Test task to repeatedly: - put until other members get OOM for off-heap memory (other members should close their cache) - do ops for a while longer - pause and validate - close all regions - validate off-heap memory - reinitialize

HydraTask_offHeapCeilingTestOOM

public static void HydraTask_offHeapCeilingTestOOM()
                                            throws Throwable

Test task for members that are expected to get OOM for off-heap memory and close their cache. Put until OOM for off-heap is detected. Wait for the signal to reinitialize.

Throws:

Throwable

doDataValidationOnce

public static void doDataValidationOnce()

logDurationHistory

public static void logDurationHistory()

log the history of ops in this member

checkOperationTimes

public static void checkOperationTimes()

As the test runs, it collects how long operations take. This looks for operations that took too long.

checkOperationTimes

public static void checkOperationTimes(String opName,
                                       long[] history)

Check if an operation took too long during this run

Parameters:

opName - The kind of operation

history - The history of timings for this operation in this member.

handleException

public static void handleException(Throwable t)
                            throws Throwable

Given a Throwable, accept it if it involves an out of off-heap memory, otherwise throw it.

Parameters:

e - The Throwable to check.

Throws:

Throwable
