Publishing reads the information needed to locate the archive entries from the
archive volume and copies the information to media database files located in the
directory pointed to by the HS_TMP environment variable. When a request for
published archive data occurs, History uses this media database to find the requested
data.
The contents of a complete volume, or even multiple volumes can be published in
relatively few steps.
This procedure may be performed through either an archive device aspect,
Figure 75, or an archive volume aspect, Figure 76.
Archive device aspects are typically located in the Node Administration structure,
under the Industrial IT Archive container for a selected node as shown in Figure 75.
Select the volume to be published, then right-click and choose Publish from the
context menu.
The media database files require a certain amount of free disk space on the hard
drive. Un-publish any volumes that are not being accessed on a regular basis to
limit the size of the media database.
