Deprecated functionality in Authoring Server in WCS 7

1. Managed Files

• The Manage Files feature in WebSphere Commerce Accelerator is deprecated for WebSphere Commerce Version 7 Feature Pack 2. This feature was used to upload new catalog files, such as images of products for your store, or to reorganize existing files.

Rcommanded Action:

• Use the Assets tool in Management Center to work with attachments, managed files, and managed directories.

2. stagingcheck utility

• The stagingcheck utility has been discontinued.

Rcommanded Action:

• As an alternative, run the stagingprop utility with the transaction parameter set to one (the default value) and the batchsize parameter set to 0. If an error is encountered during the stagingprop transaction, then the entire process is rolled back without any changes to staging or production servers.
