Field Detail

regionName

public static Long regionName

Name of region in edge and server caches

whatToKill

public static Long whatToKill

Which system component to kill

restartWaitSec

public static Long restartWaitSec

Wait period between kill and restart

killInterval

public static Long killInterval

Milliseconds between running kill task

toggleKill

public static Long toggleKill

Do we alternate between killing two cache servers? Or do we just kill a random one?

allowDisconnect

public static Long allowDisconnect

(boolean) Do we allow a shutdown of the cacheServer in addition to kills? If true, killSomething will randomly choose (per invocation). Defaults to false

getIntervalMs

public static Long getIntervalMs

Wait period between gets in doGet task

hitsPerMiss

public static Long hitsPerMiss

Number of extra gets to execute on an entry after it iss loaded in

maxKeys

public static Long maxKeys

workLoad based tests (bloom-vm) limit the key space

getBatchSize

public static Long getBatchSize

Num times to run doGet in HierCache.doGetBatch() task

databaseLoader

public static Long databaseLoader

The cache loader used by the cache server. Choices are: default, ccache, oracle. Any other value is treated as default

dbLoadTimeMs

public static Long dbLoadTimeMs

Wait period in DB loader

objectType

public static Long objectType

Type of object returned by loader such as bytearray, string, xmlstring, or the name of a class with a zero-argument constructor.

averageSize

public static Long averageSize

For the useCase1Failover.conf, this is the average size of the entries in the region

debug

public static Long debug

Whether to print debugging output

edgeMembershipListener

public static Long edgeMembershipListener

(String) className of BridgeMembershipListener for edge clients

serverMembershipListener

public static Long serverMembershipListener

(String) className of BridgeMembershipListener for bridgeServer

public static Long storeNodeData

blackboardType

public static Long blackboardType

blackboardName

public static Long blackboardName

receiveValuesAsInvalidates

public static Long receiveValuesAsInvalidates

(boolean(s)) Receive Values As Invalidates.

entryOperations

public static Long entryOperations

(Vector of Strings) A list of the operations on a region entry that this test is allowed to do, as long as the global region size is < regionSizeThreshold.

lowerThreshold

public static Long lowerThreshold

(int) The size of the region that will trigger the test to choose its operations from lowerThresholdOperations.

lowerThresholdOperations

public static Long lowerThresholdOperations

(Vector of Strings) A list of the operations on a region entry that this test is allowed to do when the region size falls below lowerThresold.

secondsToRun

public static Long secondsToRun

(int) The number of seconds to run a test (currently used for concParRegHA) to terminate the test. We cannot use hydra's taskTimeSec parameter because of a small window of opportunity for the test to hang due to the test's "concurrent round robin" type of strategy.

public static Long useOwnKeys

(boolean) For some concurrent tests, true specifies whether the test uses unique keys for each thread to avoid conflicts with random ops in other threads, or false if there are no limitations on the keys a thread can use. The test can do different validation if threads are using a unique set of keys.
