Don't set your own IDs with a counter. AppEngine's datastore will automatically assign an ID to your entities when they're first inserted, if you don't provide one. The problem with using a counter is that this is a central point that every insert will have to touch; and App Engine is not designed for scaling to high frequency writes to the same entity groups (different entity groups are no problem).

Indeed, they recommend no more than about one write per second, on average, per entity group. In short, a fixed counter will kill your performance. Use app engine's default ID assignment system unless you have a pressing reason otherwise. Pcdj Dex 2 0 Crack For Idm.

Note that app engine's IDs are not sequential, for precisely the reason that sequential IDs don't scale. @newwebdev, you shouldn't have a finite, fixed set of entity groups; this again will kill performance. Creating entity groups is a very cheap operation. For example, you could have every doctor be the root of an entity group, and have all operations performed by the doctor be in the same entity group. Then you could have a sequential counter for within this entity group. So you could, say, have operation #13 for doctor X.

What are Scopes? Scope is an object. Scopes are attached to the DOM as $scope data. This demonstrates that the properties on scope update automatically when.

But having a single global counter for all doctors is a bad idea. – Jun 27 '11 at 15:33 1.

Let’s say you’ve decided to make some custom functionality available to your users as a SharePoint 2013 app. You’ve decided that this will be published to the appropriate internal SharePoint App Catalog (as opposed to being available in the public SharePoint Store).

In a large company, it’s probably not realistic to expect all users to install such internal apps, even if we want to make the functionality available to everyone. The answer *might* be to use one of the options for deploying the app at “tenant scope”. This works for both on-premises deployments and Office 365/SharePoint Online. This article looks at these options, but just as a reminder of where we are in the overall series, here's the table of contents: • • • • • Rolling out SharePoint 2013 apps to the enterprise - tenant scope and PowerShell installs [this article] • • • • • Microsoft even provide a nice admin interface for tenant-scope installs, which offers the following deployment options: • Deployment to named site collections • Deployment to all sites under a particular managed path • Deployment to all sites created from a certain site template I said *might*. When deploying apps in this way, there is a crucial detail to be aware of – something which could either be highly-desirable or a deal-breaker. Essentially, all installed instances of the app *share* a single app web.

This means any lists or libraries you provision as part of your app, are shared amongst all the webs where the app is installed. As I say, this could be exactly how you want your app to operate, or completely against it’s design. The process for using this model is as follows: • Upload app to App Catalog. • Install the app to the App Catalog site collection – yes, for this scenario we actually have to install the app there (for reasons which will become clear later). • Go to the Site Contents page and find the app. On the callout menu here (and only here), you’ll have an action labelled ‘DEPLOYMENT’: • Click the ‘DEPLOYMENT’ button to go to the admin page.

On this page, I see the 3 options for deployment – individual site collections:.or deploying to all sites under a Managed Path, or all sites created from a certain template: Once you’ve selected appropriate options and hit OK, after a few minutes time you’ll find your app has landed in the target locations: As you can probably guess, it’s a timer job which performs the deployment. This is the App Installation Service timer job, set to run every 5 mins by default. Important aspects of tenant-scoped app installations As I highlighted before, all app instances share a single app web.

I had the same issue as well (I´m also attending the Udacity course). To me it seems to have something to do with maven - maybe the POM is outdated due to the course having been a while ago. It took me ages to make it work and to be honest I´m not even sure how I fixed it in the end. Two things I did: • check if there even is a 'local_db.bin' file (the local version of the data store). It should be in /target/conference-1.0/WEB-INF/appengine-generated/. But i guess this is the case as you say that the local API Explorer is working for you?

• update the SDK version in the pom.xml: 1.9.17 which was previously 1.9.3 In general I´m very happy how the course is structured but so far I had some terrible issues which I guess are related to the outdated material and there is no more support in the forums. When I finished the course I will go ahead and also do this course.
