If you are a lone developer working in a stand-alone environment (sometimes referred to as a single-user environment), you may want to just skip straight to the section Exporting and importing content, at the end of this chapter. Sorry, but version management in a stand-alone environment is almost nonexistent, so you"re largely on your own.

In a client/server environment, all content objects are stored on a central server. Developers create and edit content on their own workstation (typically, a PC), and then send this content to a database on the central server for storage when they have finished with it. This is referred to as checking in a content object.

If they subsequently want to change a content object that is on the server, they need to check out the content object, change it, and then check it back in. In this chapter, you will learn how to: Check in a content object Check out a content object Display the version history for an object Revert to an earlier version of an object Restore a deleted content object Export content to a backup file Import content from a backup file Import content from a previous version of UPK or OnDemand. Download at WoweBook.Com Version Management Checking in a content object When you cre pdf417 2d barcode for Java ate a content object in a client/server environment, the content object is stored in your local repository (that is, on the client side of the client/server set-up). It is important to understand that your local repository is located on your local workstation. This means that if you have a content object in your local repository, and then move to another workstation, you will not see your local version of this content object on the new workstation.

This is because they are located on the workstation on which you created them or checked them out. You should, therefore, always use the same workstation, or check in all of your content objects before moving to a new workstation..

Version Diff erence In UPK 3.5.1 client/server edition, it is possible to choose a specific location for your local repository.

. Documents th PDF 417 for Java at are checked out to your local repository are identified by a green check-mark ( ) to the left of the object details in the Library. You will need to check these objects in if you want them to be stored in the central library so they will be accessible to other developers. Generally, you should do this whenever you have finished working on a content object.

However, there are good reasons for checking in objects more frequently. Your local repository is (typically) in the C: drive of your computer, whereas the central library is on a central server. Unless you are very fastidious about backing up your PC, the chances are that the server is backed up more often than your PC, and is usually backed up automatically.

Placing your files in the central library will, therefore, provide greater security in terms of having a backup that you can revert to in the event of a disaster. In addition to this, whenever you check in a content object, a back-up of the previous version is taken. Should you need to back out your changes, you can simply revert to a back-up version of the content object.

Related to this, content objects are never really deleted from the server library. Actually, they can be deleted, but only by an Administrator, and typically as part of a cleanup. However, if you delete an object (that has never been checked in to the central server) from your local repository, it is gone.
