<h1 class="topictitle1">Device or session error on open or acquire operation</h1>
<div><p>A major return code of 82 indicates that a device error or a session
error occurred during an open or acquire operation. Both the minor return
code and the accompanying message will provide more specific information regarding
the cause of the problem.</p>
<p>Some of the minor return codes in this group are the same
as those for the 81 major return code. Device or line failures might occur
at any time, but an 82 major code indicates that the device or session was
unusable when your program first attempted to use it. Thus no data was transferred. The problem might be the result of a configuration or installation error.</p>
<p>Depending on the minor return code, it might be appropriate for your program
to recover from the error and try the failing operation again after some waiting
period. You should specify the number of times you try in your program. It
might also be possible to use an alternate or backup device or session instead.</p>
<p>Message numbers accompanying an 82 major code might be in the range indicating
either an open or an acquire operation. If the operation was an open, it
is necessary to close the partially opened file and reopen it to recover from
the error. If the operation was an acquire, it might be necessary to do a release
operation before trying the acquire again. In either case, you should specify
a wait time for the file that is long enough to allow the server to recover
from the error.</p>
