Application 09/322,698
storing a read identifier for each reading transaction,
wherein the read identifier reflects a time at which
the reading transaction first accesses an object stored
in the database; and
using the read identifiers to determine an age of an
oldest active transaction.
As a major theme of appellants' positions in the briefs and
reply brief, we note appellants' position at the top of page 13
of the principal brief on appeal that there is "no teaching or
suggestion of using read transaction identifiers to determine the
age of an oldest active transaction (i.e., transactions that read
the database, as opposed to those transactions that modify the
database), as recited by claim 1." There is no basis in the
disclosed invention merely that the read identifiers would
determine the age of any oldest active transaction per se other
than a read transaction using the read identifiers set forth
earlier in claim 1. The invention is always disclosed in the
context of determining the age of an oldest active reading
transaction as noted at specification page 7, lines 26-27;
page 9, lines 13-16; page 10, lines 9-12; the showing in Figure 6
