All Implemented Interfaces:

Runnable

public class DBCPClientThread
extends ClientThread

Client thread that executes requests in a loop using a configured DataSource, with the number of requests, time between requests and query strings governed by constructor parameters. See ClientThread javadoc for a description of how times between requests are computed.

Create a dbcp client thread.

Parameters:

iterations - number of iterations

minDelay - minimum delay time between client requests

maxDelay - maximum delay time between client requests

sigma - standard deviation of delay times between client requests

delayType - distribution of time between client requests

queryType - type of query

rampPeriod - rampup, rampdown period for cyclic load

peakPeriod - period of sustained peak for cyclic load

troughPeriod - period of sustained minimum load

cycleType - type of cycle for mean delay

rampType - type of ramp (linear or random jumps)

logger - common logger shared by all clients

dataSource - DataSource for connections

stats - Statistics container
