  • Exchange 2003 Performance and BES Activation.

    All -

    Environment: Single exchange2k3 SP2 server. AD 2003 R2. BES server: 4.1.6

    I was troubleshooting an issue this morning where most outlook users were receiving the infamous "Outlook is trying to retrieve data". I opened perfmon and almost fell out of my chair: I noticed the RPC Averaged Latency was up towards 100 and a had maximum of 359. It was averaging around 75 while one of the disks was equally slammed when reporting AVG. Disk sec/Write and Read. I opened Exmon and didn't really see any statistics for mailboxes that were abnormal. (Although I could use a refresher as to why DirtyReads affect I/O writes)

    As it turns out, as this issue with exchange was happening, my colleague was running and a BES activation for a new Blackberry Storm2. Once the activation was complete, which strangely took close to 2 hours, exchange performance resumed as normal.

    My questions is, where else should i have been looking to determine why the BES activation was killing exchange? I don't have any concrete data supporting my claim, but exchange has been buzzing along since and EXmon stats look close to the same since the BES activation as stopped.

    why not just run another activation and see if it does it again. that would prove your point, then you could go from there.

    I gotta say.. your setup was what I was on only 3 weeks ago, and I never noticed a huge spike in my stats while activating.

      Thanks Daniel. Prior to this occurrence, I never noticed such a spike. I'm definitely going to run another activation, but my question still is -- how will i be able to pinpoint the cause for the spike ? Which tool or monitoring which specific metric will report or prove definitive enough for me to support the fact that activation is causing the spike ?

        If you were doing 500 activations on poor hardware, then it might be a cause of performance problems. However a single user is the equivalent of 5 regular Outlook users, so unless your hardware is poor it shouldn't cause a problem. I suspect it has to be something else.

        Run the Exchange Performance Troubleshooting tool against the system and see whether it flags anything of interest.

          Thanks Simon. I suspect it may be something else, but all the evidence I've gathered so far hasn't suggested it could be anything else, hence the inquiry into what i should be looking into. Nevertheless, thank you for the suggestion and I'll report back with my results.

          Harry.
