    Avid Editor Db Engine service fails to run- I'm clueless, help !

    I have noticed the problem lately while finishing an old project, using MC 18.12.10: background transcode would not start, but report an error.
    I dismissed that assuming it was some kind of corruption carried forward in that 4-years old project and went ahead finishing the project before installing 20.10 from scratch (almost: a few projects and some other folders were not deleted before installing 20.10)
    But now in 20.10, I realize that not only is it still impossible to launch background transcode, but also the "Avid Editor Db Engine" service fails to start (no error logged) while MC seems to be fully functional, except for background jobs.

    I have absolutely no clue why this (probably essential) service fails to run (when manually started in Windows Service Manager, I get "The Avid Editor Db Engine service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs").

    Could this be an A/V or Firewall issue ? I use the Win10 built-in protection tools.
    Or some corrupt file/folder/registry entry ? Sotware conflict ???
    I tried reinstall/repair...no change.
    On my other (lighter) PC, MC First 20.10 runs just fine, including the "Avid Editor Db Engine"....
    Searching the Internet for "Avid Editor Db Engine" doesn't return many things.....

    I'm clueless......

    Re: Avid Editor Db Engine service fails to run- I'm clueless, help !

    is there a way to create/increase logging for this service: if only I had some error in a log somewhere ????

    Also, what database (used internally by the service) could be corrupt ? The obvious Avid MediaFiles folders are clean.

    Have you tried to deleted the dB and let Avid rebuild? (Before deleting I rename those 2 items as .OLD so I still have them, although it may be mute point in your case, but doesn't hurt.)

    Re: Avid Editor Db Engine service fails to run- I'm clueless, help !

    Yes, I did

    What puzzles me is that, while "Db Engine" looks like a core MC service to me, the only symptom [so far] is that attempting to do a background transcode immediately results in "The Production Services Engine was unable to make a connection", most probably b/c the background transcode engine fails to comunicate with the Db Engine.

    You are logged in as administrator? Check your startup services in Windows settings, look for something new. Also check anti virus logs for recent entries.

    Re: Avid Editor Db Engine service fails to run- I'm clueless, help !

    I am not logged in as admin, I never did (I always used a local normal user account to work, it worked for me since the early days of Windows XP); the offending service is set to run using the Local System account, as all other Avid services. Same on my secundary system.

    When I open a CMD box as admin, and type 'net start "Avid Editor Db Engine"', it says that the service has started successfully (but when you look at the Task Manager/Services or Computer Management/Services, the service is NOT running: this indicates that the service is able to start, but will immediately stop; exactly like when manually started in Windows Service Manager, I get "The Avid Editor Db Engine service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs"). I would tend to believe there is nothing wrong with permissions.

    Unfortunately there is nothing relevant to see in the Windows logs (Application, Security (just a couple of "Audit Success" entries) & System).

    I checked the Windows startup using advanced tools, scrutinized running processes, compared Services entries with my other PC (whith MC First, same version, where the Db Engine service runs fine).

    I am afraid that, unless someone has a better idea, I will have to completely wipe MC on this system, including all reg keys found with the word "Avid"....and go through the burden of reinstalling/reactivating licensed add-ons :-(((

    Re: Avid Editor Db Engine service fails to run- I'm clueless, help !

    Well, how bad is it ? Very bad !

    I uninstalled MC, then carefully deleted all Avid entries in:

    - [User]\documents

    - Public Documents

    - C:\programdata

    - c:\[user]\appdata\local

    - c:\[user]\appdata\Roaming

    - All entries containing "Avid" in the Registry

    Then I reinstalled MC....and the problem is still there !!!!! So I guess there is a conflict with a piece of code or a setting on my system [:'(]

    Looks like the only way out is to clean reinstall the OS (and all other apps, settings and data) -- I had hoped for a better Xmas gift ...

    i created a case for this - 04079461

    See if support can assist via engineering as I have never seem this one.

    Oh that's great Marianna, thanks Yes - if I could get some hints about where to continue further t'shooting...not knowing what the Db Engine is touching, I have no clue where to search next.

    Re: Avid Editor Db Engine service fails to run- I'm clueless, help !

    After much time wasted in testing & trying, I may have found the culprit:

    For my class of (AVID supported) laptop, DELL provides a performance optimization tool called "Dell Precision Optimizer" (DPO) which has a number of pre-learned profiles, supposedly tuned by the manufacturer of each listed app, one of them being "Media Composer by Avid".

    I discovered that simply running this app in one of its latest incarnations (6.4.5 as of today) once, even without selecting any profile or doing any other "tuning", causes the "Avid Editor Db Engine" service to fail starting, permanently.
    To make things worse, uninstalling DPO does NOT make the service startable again !!!!!
    It looks like once the utility has run, even without 'making any change', it leaves some tracks in the system forever, that neither DPO uninstall nor MC uninstall/reinstall can fix !!!! W?F.

    There are however still unexplained strange things:
    On a pristine Windows installation, I can easily repro the scenario where, after installing just the Dell drivers (but *not* DPO) & MC, all Avid services run fine; as soon as I install & run DPO, "Avid Editor Db Engine" service fails to start; from there, some random, clumsy manipulations with DPO (uninstall, stop related services, install an earlier version, etc.) sometimes result in being able to start "Avid Editor Db Engine" service again, but generally, once DPO has run once on a clean Windows installation, the service will never start again.
    Unfortunately, when I restore the full image backup I took just before my destructive tests, I haven't found a way to make the Db Engine start successfully again, even when deinstalling DPO, or doing one of the 'clumsy manipulations' that would work on a clean Windows installation. This leaves me with just the option of starting with a pristine Windows and go through the painful process of reinstalling all my drivers, apps, documents, licenses, preferences and settings etc. (my laptop is not dedicated to MC editing) - kind of thing you don't do when you don't have to.[:'(] Angry

    I will chase Dell with this, but frankly, I don't expect more than a ping-pong game between Dell and Avid.

    From this community, I'd like to hear if anyone is successfully running MC on a Dell laptop with (a recent version of) DPO installed.

    For Avid folks monitoring this, I wonder how much Avid is/was involved in providing system tuning guidance to DELL to create the DPO pre-learned "Media Composer by Avid" profile ? Perhaps that 'pre-learned' profile hasn't been updated since long, and is no longer suitable for recent versions of MC ? When blessing/supporting MC on the Precision P5530 or any DELL laptop in that category, does Avid engineering or support do anything with DPO ? Does Avid even know what kind of tuning made by this utility could be beneficial for MC performance / what MC optimization do I lose by not using DPO on this particular system ? Or is Dell engineering doing this on their own ?
