E1176: Ggate, a new connect from GTWriter could be rejected

Product: Ggate
Platform: Windows
Status: Fixed for R6.5, fix available for R6.4
Last updated: 2008-01-03 14:02:36

The attached printer (-PCO) for a copy of Glink connected by Ggate
could occasionally reject a new connect from GTWriter on GCOS7.

The default configuration for a terminal (TERM/TWDEST) in GTWriter
is to connect to the printer node/mailbox when a report is queued,
and disconnect when there are no more reports queued for the
TERM/TWDEST. If an application or user queued a new report just
after the disconnect process was started, the new connect could be
rejected with mailbox busy.

The disconnection was taking a couple of seconds, leaving a timing
window during which the printer mailbox was still busy from the first
report when the new connect arrived. The slow disconnect was caused
by Ggate trying to use the traditional DSA transport disconnect
protocol and waiting for a reply to a transport disconnect request
until a two second time-out fired.

GTWriter retries the connect each minute, and so the second report
was delayed for a short time, but delivered on the first retry.

The DSA transport disconnect protocol is now dropped, since it is not

The work-around is to use the GTWriter 'KEEP' option for the
TERM/TWDEST to avoid disconnecting the attached printer.
