When we look at data we occasionally get the reading "arc off-line" . what does this mean and how do we eliminate this from occurring?
Hi Karen Kuhn,
Arc Off-Line is a marker to indicate various things during data retrieval. It is meant to be an indication that the retrieved data may have compromised integrity, like an archive gap for instance.
I'd recommend reading the following article to understand what it means, and how to control it with the MarkArchiveGaps tuning parameter.
