Scheduling a daily task

Hi list,

I'd like my app to take a snapshot of the DB once a day, is there some standard way to do so?

Thanks!

I've finally used a regular Smalltalk process, it seems to work okay :)

Hi Bernat,

If you're using Squeak/Pharo, the Scheduler package is maybe what you're
looking for:

Hi Bernat,

There are WebScheduler (and WebSchedulerEvent) classes in Aida and they
are quite independent, they can be used in Iliad too. Also there you can
see how a hourly snapshot is done, see AIDASite #initHourlySnapshot,
class #imageSnapshot.

Best regards

Re: Scheduling a daily task

Cool, I'll take a look at both options.

Right now I'm doing:

self isSchedulerOn

ifFalse: [

Scheduler := [

[

(Delay forDuration: 1 day) wait.

self takeSnapshotTriggeredBy: #dailySnapshot ] repeat ] forkAt: Processor lowIOPriority ]

Which seems to work pretty well, and for stopping it:

self isSchedulerOn

ifTrue: [

[ Scheduler isTerminated ] whileFalse: [ Scheduler terminate ].

Scheduler := nil ]

I'll still look at both other options, though. They seem more professional than my clutch ;)

Thanks!
