Direct Known Subclasses:

PersistentRecoveryOrderOldConfigDUnitTest

public class PersistentRecoveryOrderDUnitTest
extends PersistentReplicatedTestBase

This is a test of how persistent distributed regions recover. This test makes sure that when multiple VMs are persisting the same region, they recover with the latest data during recovery.

Method Summary

Modifier and Type	Method and Description
protected AsyncInvocation	createPersistentRegionAsync(VM vm, boolean diskSynchronous)
void	doTestPersistConflictOperations(boolean diskSync) vm0 and vm1 are peers, each holds a DR.
java.util.Properties	getDistributedSystemProperties() Returns a Properties object used to configure a connection to a DistributedSystem.

protected com.gemstone.gemfire.internal.cache.versions.RegionVersionVector	getRVV(VM vm)
protected void	putAnEntry(VM vm0)
static void	resetAckWaitThreshold()
void	testCloseDuringRegionOperation() disabled since the test tries to check for NoDataStoreAvailableException while that is thrown only for GemFireXD system (see #48061)
void	testCompactFromAdmin() Tests to make sure that we stop waiting for a member that we revoke.
void	testCrashDuringGII() Test to make sure that if if a member crashes while a GII is in progress, we wait for the member to come back for starting.
void	testCrashDuringPreparePersistentId()
void	testDontWaitForOldMember() Use Case AB are alive A crashes.

void	testRevokeAMember() Tests to make sure that we stop waiting for a member that we revoke.
void	testSimultaneousCrash() Tests that if two members crash simultaneously, they negotiate which member should initialize with what is on disk and which member should copy data from that member.
void	testSplitBrain()
void	testSplitBrainWithNonPersistentRegion()
void	testTransmitCrashedMembers() Tests that persistent members pass along the list of crashed members to later persistent members.
void	testTransmitCrashedMembersWithNonPeristentRegion() Tests that even non persistent regions can transmit the list of crashed members to other persistent regions, So that the persistent regions can negotiate who has the latest data during recovery.
void	testWaitForLatestMember() Tests to make sure that a persistent region will wait for any members that were online when is crashed before starting up.
void	testWaitingMemberList() Test which members show up in the list of members we're waiting on.
