Now then, tell me this:
When should I do Quick, as opposed to Complete Optimize Database.
Is one more frequent - the other now and then, or what?
Well obviously one takes longer, so you ca do the quick one when you don't have time for the complete. Honestly though, I have a *HUGE* database (~1.3gb) and 99% of the time there is minimal performance difference, I doubt it can be noticed without a stopwatch.
And should I close MM4 after/before running these Maintain Library functions.
I do, just to make sure there isn't anything running before the job, and to make sure everything is written/saved afterwards.
For me Complete takes a considerable time to finish its job.
complete is completely (pun intended) dependent on how fast your cpu and hard disk is. If you watch the mm.db folder, you can see it basically creates a new one by building up the database journal/lock file, creating a new empty database then dumping all the transactions to the new db file.
There is no progress bar to tell be how it is behaving.
unfortunately sqlite itself does not provide any progress feedback for MM to display.
Sometimes it just hangs there forever and after a long wait I have to kill it - which means that I loose the last played info among other things. Grrhh.
yeah I think this happens sometimes if a background script or process tries to do something while in the middle of an optimize, which is why I restart MM before and after.
File | Maintain Library | Optimize Database seems to have a mind of its own and does not keep me informed of what is happening.
as above, this is more of a sqlite issue, watch the folder where the mm.db is, you can see the files changing as it processes. If the files don't change in a long time, then it might be locked up, but otherwise you should always let it complete on its own, otherwise you risk losing data and/or corruption.
