Resolution:
Directory Replication enables you to coordinate and synchronize files from your Manager to Engines. You can use this to ensure that Engines all have the latest version of a library, file, data set, or other resources needed to complete work.

By default, the Directory Replication mechanism automatically looks for files in a predefined directory (typically deploy/resources, within the livecluster directory on the Manager. This contains six directories, one for each OS supported and a shared directory, replicated to all OSes.) During each check of the directory (the default is once per minute), if it notices changes, it sends the new files to each Engine. It also forces the Engine to log out and log back in. This interrupts any current work, but it also ensures that work isn't completed with incorrect libraries or data.

You can also manually trigger a file update to ensure all Engines have the same files.

To upload files and manually trigger an update:

   1. Click the Services tab.
   2. Click Resource Deployment.
   3. Add your files to the Manager by clicking directory names to navigate to a directory. Then click Browse to find a file on your PC, and Upload__to upload it to the Manager.
   4. You can also place files in the livecluster/deploy/resources directories on the Manager. There are OS-specific directories for Engines running on Linux, Solaris, zLinux, and Win32 machines, and a shared directory which is copies to all Engines.
   5. Click the __Update button.
