Field Detail

lockOperations

public static java.lang.Long lockOperations

(boolean) True if the test should use locking.

entryOperations

public static java.lang.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 java.lang.Long lowerThreshold

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

lowerThresholdOperations

public static java.lang.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.

upperThreshold

public static java.lang.Long upperThreshold

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

upperThresholdOperations

public static java.lang.Long upperThresholdOperations

(Vector of Strings) A list of the operations on a region entry that this test is allowed to do when the region exceeds upperThresold.

numOpsPerTask

public static java.lang.Long numOpsPerTask

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

losingPartition

public static java.lang.Long losingPartition

(String) Indicates the host (host1 or host2) NOT expected to survive a NetworkPartition. This is used when Shutdown and CacheClosedExceptions are encountered to determine whether or not they should be accepted. Expected values are literally, host1 or host2.

hostDescription1

public static java.lang.Long hostDescription1

(String) Indicates the HostPrms-name for the first remoteHost (remote from Master). Used by SBUtil for network drop/restore. Defaults to 'host1'.

hostDescription2

public static java.lang.Long hostDescription2

(String) Indicates the HostPrms-name for the second remoteHost (remote from Master). Used by SBUtil for network drop/restore. Defaults to 'host2'.

hostPairsForConnectionDropRestore

public static java.lang.Long hostPairsForConnectionDropRestore

(Vector) Indicates the HostPrms-names for all the remoteHosts (remote from Master). Used by SBUtil for network drop/restore. Defaults to 'host2'.

expectNoDatastoreExceptionOnAccessor

public static java.lang.Long expectNoDatastoreExceptionOnAccessor

(Boolean) Expect no datastore found exception on accessor nodes. This is specific to certain scenarios where we lose datastores due to network partitioning etc.

enableNetworkHelper

public static java.lang.Long enableNetworkHelper

(boolean) Whether or not to execute the NetworkHelper (drop/restore) commands. Defaults to true. This can be set to false in a local.conf to disable the NetworkHelper commands (to allow testing when multiple boxes are not available for exclusive use).

dropType

public static java.lang.Long dropType

(String) Indicates the dropType (ONEWAY or TWOWAY) for network drop/restore commands. Defaults to TWOWAY. 5/20/08 - all tests now use dropType.TWOWAY only.

dropWaitTimeSec

public static java.lang.Long dropWaitTimeSec

(int) dropConnections will sleep for dropWaitTimeSec after dropping the network connections. This allows serial tests to 'settle' after the network is dropped. For example, serial PR tests which need to re-establish redundancy after the drop. (defaults to 0)

useTransactions

public static java.lang.Long useTransactions

(boolean) True if the test execute operations within a single transaction Defaults to false

commitPercentage

public static java.lang.Long commitPercentage

(int) In transaction tests, the percentage of transactions to perform commit (vs. rollback). Default = 100%.

secondsToRun

public static java.lang.Long secondsToRun

(int) The number of seconds to run before terminating 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.

maxKeys

public static java.lang.Long maxKeys

(int) maximum number of keys to create while loading region See NetworkPartitionTest.loadRegion()

coordinatorOnLosingSide

public static java.lang.Long coordinatorOnLosingSide

(boolean) whether or not the coordinator is on the losingSide of the networkPartition (for NetworkPartition tests only). Affects validation. Defaults to false

isGiiClient

public static java.lang.Long isGiiClient

(boolean) Indicates giiClients (for gii NetworkPartitionTests) Needed to determine if validation of regionSize required. Defaults to false

expectEmptyRegion

public static java.lang.Long expectEmptyRegion

(boolean) Indicates getFromOne (replicate) getInitialImage. When this is interrupted by a FORCED_DISCONNECT, we clear the region (so we should verify that the region is indeed empty). Used by NetworkPartition-giiPref tests

giiDataPolicy

public static java.lang.Long giiDataPolicy

(String) DataPolicy for giiClients in gii NetworkPartition tests.

unhealthiness

public static java.lang.Long unhealthiness

(String) How to cause an unhealthy vm. Can either be "sick" or "slow".

playDead

public static java.lang.Long playDead

(String) Whether to combine a dead vm with unhealthinessSelection.
