What is the default behavior for SCCM downloading packages into the SCCM ccmcache area?
Here's what we're seeing when installing a package on a "clean" test machine:
A subfolder is created in the ccmcache area (typically named 1, 2, 3, ... a, b, c, etc.)
A temp subfolder is created in the ccmcache area as well. Named the same as the package cache folder created above with .tmp added. Now I have a, and a.tmp folders for example.
The package starts to download into the "a" subfolder, but not how I would expect.
First, all of the folder structure in the package is created in the ccmcache area. The foldernames are correct. There are no files yet. This can take 10-15 minutes. All I have is a directory structure.
Next filenames start showing up in the subfolders. However, they are all zero sized files, and they have temp filenames, not the real filenames. Again this takes 10-15 minutes.
Next the zero sized files begin to download content. This is the actual downloading of the files. They still have temp filenames. (The package I'm working with is 4.3 Gig).
After the file content has completed the download, all of the temp filenames are renamed to their original file names. Again this takes about 10-15 minutes.
After all this, the software installation actually starts. The SW installs in 17-19 minutes.
Is this the expected behavior? Why not just DL everything in a typical method like you'd see with a copy, xcopy, or robocopy type command?
Any help is away appreciated.
Background:
I only work on creating the SW packages, not on administration of the SCCM tool itself, so I'm not familiar with how the SCCM delivery method is actually setup.
SCCM 2012
Working on a development server, so the package is not available to all yet.
Test machine is a typcial Win7 x64 VM.
The package is primarily a drag and drop application. 4.3 Gig in size.
The files in the package are not compressed.
Virus scanning is disabled for the ccmcache directory.
I just switched to packaging w/ the SCCM tool, so please forgive my ignorance with the tool at this time.
