Class AdminHelper

java.lang.Object

util.AdminHelper

public class AdminHelper
extends Object

Helper class to initialize a hydra client VM as an Admin VM. These VMs will be admin only; they do not host a GemFire Cache. Ensure that at least one other member of the DistributedSystem is initialized prior to initializeAdminDS() as this method waits for the other members to be active before returning. (So, using this method as an INITTASK prior to initializing Cache Client VMs will cause HydraTask_initializeAdminDS() to hang).

Method Detail

getAdminDistributedSystem

public static com.gemstone.gemfire.admin.AdminDistributedSystem getAdminDistributedSystem()

accessor method for the one AdminDistributedSystem for this VM

HydraTask_initializeAdminDS

public static void HydraTask_initializeAdminDS()

Create and connect to an admin distributed system

HydraEndTask_waitForReconnect

public static void HydraEndTask_waitForReconnect()

ENDTASK to wait for distributed system to reconnect

initializeAdminDS

public static com.gemstone.gemfire.admin.AdminDistributedSystem initializeAdminDS()

Create and connect to an admin distributed system.

startAgentTask

public static void startAgentTask()

Hydra task to start JMX agent and connect it to an admin distributed system. This must be invoked as an INITTASK prior to initializing an AdminDS (with adminInterface = JMX).

waitForSystemMembersTask

public static void waitForSystemMembersTask()

Hydra task to wait for all system members to appear. The expected number of system members is the number of VMs in the test.

waitForSystemMembers

protected static void waitForSystemMembers()

Wait for the number of system members to be equal to the number of VMs
