IMAGE enhancement to provide information about database
remains frozen in design debate
At
this years special interest group meeting for IMAGE users, a
glut of good cooks in the e3000s database kitchen is keeping an
IMAGE enhancement stuck in design. The Enchilada proposal first
crafted a year ago by SIGIMAGE members got another round of
discussion at the SIG 3000 meeting, but no consensus on the metadata
delivery vehicle could be concocted. Now the group has voted to
publish four alternative recipes to get the enhancement heated up
again.
Its not for a lack of good ideas. Four separate
designs on where the metadata for IMAGE/SQL databases might be stored
are on the table, according to SIGIMAGE executive committee (SIEC)
chair Ken Sletten. Sletten was returned to the leadership of the SIG
for the fifth straight year at the all-day meeting.
Were basically stuck, Sletten said.
Were presented with four options: Enchilada information
in the root file; in datasets in the database in question; in a
privileged mode file separate from the database; or in another
database or databases. The SIEC failed to come to consensus.
Members of the special interest group, who have HP lab
engineers ears on what should be developed in IMAGE, agree on
the need for the Enchilada. The enhancement is so named because it
stands for Enhancement for Caching of Limited Authorized Data, and
was first suggested by SIEC member Steve Cooper at a New Mexico
meeting of the group in late 1998.
When we were looking at all the ballot items, it
looked like several of them would be much easier to do if there were
a place where we could store extra information on the database,
Cooper explained. A number of items would have been facilitated
if this facility were built into IMAGE. It does nothing on its own
but it makes it a lot easier to implement a bunch of other
things that were on the SIGIMAGE ballot. We got bogged down on the
technical details before we even decided if we wanted this thing or
not.
SIEC member Nick Demos brought the issue before the
attendees at this years meeting to attempt to break the
technical deadlock. The concept goes against the traditional
way of doing enhancements, Demos said. We have a whole
set of possibilities [with this]. We have to talk about what
HPs posture is on this will they take something
thats not exactly votable as an enhancement and consider
it?
Tien-You Chen, the database engineer from HP present for
all of the days discussions with customers, said in reply that
hed gotten clear instructions from his manager Jon Bale.
Before he left, Jon said, Dont promise
anything.
Sletten noted that 11 items on the current SIGIMAGE
enhancement ballot are related to the Enchilada meaning that
if HP were to build the enhancement, those items could be developed
more quickly and cost effectively.
Even without consensus, Cooper said the Enchilada might
already have accomplished something for HP and e3000 customers.
Maybe we succeeded at one level, in that when Jon and Tien-You
go to do these enhancements, if they think out of the box and
weve communicated the concept and they run with it, maybe
weve done what we need to. At first it looked like the great
unification theory, but I dont think thats the case
anymore. Maybe its not the job of the SIEC to solve the
[debate].
A
full day of last years SIGIMAGE meetings was devoted to
discussion and debate over just the Enchilada proposal. The group
hasnt given up on the idea. Members voted to have the four
designs summarized in two-page technical briefs by the leading
proponents of each idea. The briefs will be submitted to Demos this
month.
