Solution or Workaround
What are the possible causes when the following message occurs in ARCEDIT?
ACT Channel 1 Not Open
Bailing out of ARCEDIT .....
The message could indicate that all the swap space is being utilized. Generally
this situation will occur when additional users are on the system or when a
single user begins to run two or more ARC sessions at a time. Each additional
user of ARCEDIT uses roughly 30 MB of additional swap. For every new window
(e.g.: PAN/ZOOM), additional swap is being accessed. Processes independent of
ARC/INFO also use swap. See installation manuals for swap space recommendations
for ARC/INFO as each platform has different requirements.
A second possibility is that all available system channels are being used.
Every time an editcoverage, backcoverage, and/or snapcoverage is declared,
channels are being filled up. The channels will remain filled up unless they
are emptied. When this limit is reached then the session fails.
For insufficient swap space, increase swap allocation as appropriate for the
platform in question.
For channel errors use REMOVEEDIT, REMOVEBACK, and REMOVESNAP frequently. Do a
SAVE prior to issuing the commands or edits will be lost.
ACT stands for ARC COORDINATE TABLE.
