“There’s a new player in town!” DISTRIBUTED REPLAY
So what’s Distributed Replay? SQL Server 2012 feature Available in all editions (kind of…) Works with 2005 and higher (kind of…)
Distributed Replay Components 1. Administration tool – the cmd tool to manage the replay 2. DReplay Controller – the brain behind the replay 3. DReplay Client – machines(up to 16) that replay the workload 4. Target Server – The SQL Server instance you replay against
OK, but how are they working together?
DEMO Setting up DReplay Environment (installing gotchas)
Installation requirements and gotchas 1. Services must run under domain user accounts 2. Firewalls must allow the traffic of DR Components 3. DCOM permissions must be configured 4. SQL Server logins for the clients need to be created
So how do we issue a replay?
Step 1: Capture a trace!
Step 2: Preprocesses the .trc file/s
Step 3: Decide on replay mode and options
Step 4: Replay the preprocessed trace
DEMO The Replay Process!
Replay your workload. The steps. 1. Capture the workload with Profiler (TSQL-Replay) 2. Preprocess the trace with “dreplay preprocess” 3. Decide on a mode – synchronization or stress 4. Replay the workload with “dreplay replay” 5. Analyze the results
The GUI that is in beta from 2011
At the end 1. The Tool for replaying mission critical workloads 2. Don’t be afraid of not having a GUI 3. Capture -> Preprocess -> Replay 4. Document, blog, share it with the community!
