17. How Configuration Collection Replay Results 17

18. Configuration 18

19. Configuration C:\Program Files (x86)\Microsoft SQL Server\110\Tools Controller configuration file DReplayController.config Client configuration file DReplayClient.config \binn Preprocess configuration file Dreplay.exe.preprocess.config Replay configuration file Dreplay.exe.replay.config

24. Configuration - Replay 24

25. Configuration - Replay Configuration  Target instance  Sequencing  Stress scale granularity  Connect timescale  Think time scale  Use connection pooling  Health monitor interval  Query time out  Threads per client

26. Configuration 26

27. Configuration Restart the services on all the servers NET STOP “SQL Server Distribute Replay Controller” NET START “SQL Server Distribute Replay Controller” NET STOP “SQL Server Distributed Replay Client” NET START “SQL Server Distributed Replay Client” On each server that has the services installed 27

28. Configuration The Rest of the Story....... 28

29. Configuration Check for errors C:\Program Files (x86)\Microsoft SQL Server\110\Tools\DReplayClient\Log Failed to connect controller with error code 0x80070005 Error code 0x80070005 means “Access is denied” 29

56. Uses and Results UsesResults  Application load testing  Physical vs Virtual computing  Metrics for distributed computing  TDE load  System upgrades  Hardware upgrades  Index tuning  Tables  Graphs  Analytics  Metrics

57. Results – Read Latency

59. 59 Change in Domain

60. Controller configuration file DReplayController.config Changes location when you change domains Client configuration file DReplayClient.config Modify location in the configuration 60

61. Common issues Error DReplay The client ‘ClientServerName’ is not a registered distributed replay client. Make sure that the SQL Server Distributed Replay Client services is running on ‘ClientServerName’, and that the client is registered with the controller ‘localhost’. 61
