Method Detail

HydraTask_initAccessor

public static void HydraTask_initAccessor()

Creates and initializes the singleton instance of MemManTest in this VM.

HydraTask_initDataStore

public static void HydraTask_initDataStore()

Creates and initializes the singleton instance of MemManTest in this VM.

HydraTask_initDistributedRegion

public static void HydraTask_initDistributedRegion()

Creates and initializes the singleton instance of MemManTest in this VM.

HydraTask_rebalance

public static void HydraTask_rebalance()

Run a rebalance.

HydraTask_rebalanceOnce

public static void HydraTask_rebalanceOnce()

Run a rebalance one time for all threads in all vms. This is run when things are silent, so validation can be done.

HydraTask_verifyPRMetaData

public static void HydraTask_verifyPRMetaData()

Verify PR metadata on all PRs.

HydraTask_verifyPrimaries

public static void HydraTask_verifyPrimaries()

Verify primaries on all PRs.

HydraTask_verifyBucketCopies

public static void HydraTask_verifyBucketCopies()

Verify data in the PRs.

initializeRegion

public com.gemstone.gemfire.cache.Region initializeRegion(String regDescriptName,
                                                          int localMaxMemory)

Create a region with the given region description name.

Parameters:

regDescriptName - The name of a region description.

localMaxMemory - The localMaxMemory to use for this region.

initializeInstance

public void initializeInstance()

Initialize this test instance

HydraTask_doOpsBeyondCritical

public static void HydraTask_doOpsBeyondCritical()

Do random ops that are heavy towards creates until the system becomes critical, then run beyond that.

HydraTask_doQueryAndIndexOps

public static void HydraTask_doQueryAndIndexOps()

Do query ops that will take the system to critical. Continue to run to make sure system does not reach OOME

HydraTask_doOpsUntilCritical

public static void HydraTask_doOpsUntilCritical()

Do random ops that are heavy towards creates until the system becomes critical.

HydraTask_doOpsNotCritical

public static void HydraTask_doOpsNotCritical()
                                       throws com.gemstone.gemfire.cache.LowMemoryException

Do random ops without expecting system to go critical.

Throws:

com.gemstone.gemfire.cache.LowMemoryException

HydraTask_doGC

public static void HydraTask_doGC()

Do a gc once in this VM

doOpsWithHeavyCreates

protected boolean doOpsWithHeavyCreates(long millisToRun,
                                        boolean allowCritical)
                                 throws com.gemstone.gemfire.cache.LowMemoryException

Do random operations that heavly lean toward new entry creation.

Parameters:

millisToRun - The number of milliseconds to run the ops.

allowCritical - If true, then allow LowMemoryExceptions.

Throws:

com.gemstone.gemfire.cache.LowMemoryException

doQueryAndIndexOps

protected boolean doQueryAndIndexOps(long millisToRun,
                                     boolean allowCritical)
                              throws com.gemstone.gemfire.cache.LowMemoryException

Throws:

com.gemstone.gemfire.cache.LowMemoryException
