      com.sun.slamd.example.LatencyCheckMasterThread

All Implemented Interfaces:

java.lang.Runnable

public class LatencyCheckMasterThread

extends java.lang.Thread

This class defines a thread that will periodically make changes to an LDAP directory server so that another thread can watch for those changes to appear on a replica. This makes it possible to measure the replication latency between the master and the replica.

Field Summary

Constructor Summary

LatencyCheckMasterThread(ReplicaLatencyCheckJobClass jobThread, java.lang.String masterHost, int masterPort, java.lang.String bindDN, java.lang.String bindPW, java.lang.String entryDN, java.lang.String attributeName, int latencyDelay)
Creates a new latency check master thread based on the provided information.

Method Summary

void	run() Periodically makes changes to the specified entry in the directory.
void	startChecking() Indicates that this thread should start performing modifications against the directory server.
void	stopAndWait() Indicates that the check thread should stop running and waits for it to do so.

                         throws netscape.ldap.LDAPException

Creates a new latency check master thread based on the provided information.

Parameters:

jobThread - The job thread with which this check thread is associated.

masterHost - The address of the directory server.

masterPort - The port of the directory server.

bindDN - The DN to use to bind to the directory.

bindPW - The password to use to bind to the directory.

entryDN - The DN of the entry to be modified.

attributeName - The name of the attribute to modify.

latencyDelay - The minimum length of time that should pass between modifications.

Throws:

netscape.ldap.LDAPException - If a problem occurs while establishing the connection to the directory server.
