Testing Failure at a ^WRITE
When the GDSX primary process was stopped, the requester received file-system
error 210 on its WRITE and completed its transaction processing loop as if the WRITE
had been completed normally. The requester is designed to let the
DEVICE^HANDLER retry the WRITE.
After the takeover, processing within the DEVICE^HANDLER was the same as
described above after a WRITEREAD, down to the CASE RQST^TYPE OF statement,
where it was determined that the operation was a WRITE. Then normal processing for
a WRITE was retried, and the transaction was completed.
At the TACL terminal, stop the GDSX process, confirm that the requester has stopped
as well, and log off all terminals.
