- User states (glossary)
It is common that WSI data is not stored on the local drive, but on a shared (high-capacity) storage device. There are several reasons why this may be the case:
PMA.core therefore lets your map root-directories on a (shared) network drive. A UNC-path to a networked directory looks like
\\servername\sharename\dir\subdir\. There are three conditions for this:
If no immediate access is possible for the share, you may specify impersonation information (which should be provided to you by the system administrator who's responsible for the machine that you're trying to reach). Impersonation information is verified, and the root-directory may only be created if impersonation is successful.
You must specify a domain. If no domain-name was given to you (e.g. on a Samba-share), you may enter “.” as a default domain.
When a UNC share does not exist, the following error message is displayed:
Note that you can only map network locations through their UNC path. PMA.core does not allow mapped (network) drives to be referenced directly. If
\\servername\sharename\ is mapped as drive
X:, you can not create a root directory with the path reference
x:\dir\subdir\. The reason for this is twofold:
x:\dir\subdir\foo.svsare the same files (at least not in a simple straightforward manner)
x:drive-letter will always be available (especially when no actual user is logged into the system).
In many organizations, it is commmon to map network paths to a drive letter. It's easier to remember that all the images are stored on the shared I: drive, rather than in the k
\\server_emea_48F\content\shared\incoming_slide_data\. PMA.core needs the latter path however to be able to mount content, rather than the I: drive letter. You cannot use the
I: drive letter as a reference when attaching a new mounting point to a root directory.
The reason for this is that your I: drive letter is a transient designation that only exists when you're logged in. In a server content (PMA.core is a server application running on Microsoft IIS server), the software runs unattended (i.e. without a human being logged on to the machine). The drive letter therefore is not available (in unattended mode), but the network path is.
Think of root directories then as PMA.core's own alternative to mapped network drive letters on your local computer.
