We have researched database replication and have
determined the following:
- Of the various solutions Microsoft suggests the
only one that may be at all viable is their Replication
Manager. We currently do not have Replication Manager and so it would be
atleast 2 weeks before we had any real idea if this would even work.
From their documentation there is one potention problem with using Replication
Manager in that it does not do one-way replication, so any change in the
replicated database would be reflected in the master database.
- The other issue with trying to use database
replication is that GEMS uses unigue keys for all records including the audit
log records. Therefore if GEMS was run on both database there would be
conflicts in the Audit Log when trying to replicate.
Therefore we do not
recommend pursueing database replication.
As for Puerto Rico's desire to produce custom
reports, etc there are three option avalable to them with the current
system.
- First choice Use export
results to export the data and then import into a new database
- Second choice Use the output
from ResultsMonitor as various customers have, including Montreal
Quebec.
- Third choice User the
Regional features of GEMS. Setup the 'Master' database as a 'Regional' site,
upload to this database and then using the Regional Results Server transfer
the results to the second database ("Host"). To use the option a second
region "Master" needs to be created, all the vote centers need to be set to be
in this region, a user needs to be setup to use this region and you must login
as that user for uploads. Note: currently you need to login as a
"Host" region user to be able to re-set the election.
- Not Recommended but possible
Directly connect to the GEMS database, as King County
has.

Subject: Mirror Image MDB linked to GEMS
MDB
Jurisdiction: San
Juan, Puerto
Rico
Date
Requested: April 3,

Date
Required: May

is June 30th, but need to test and have ready by May 20th.
Puerto Rico needs a
mirrored MBD file system that linked to the protected GEMS MDB file. This MDB
must be resident on are GEMS server and it must be open and accessible by
their MIS dept. The intent is to have them integrate our results to
their existing IBM main frame and their existing reporting application
software. This is required instead of export of results that we normally
do since they have developed their own jresults type application were it needs
to be a live presentation to the press and to the public. At the same
time they hang terminals off their mainframe to allow TV, Radio, and Print
media to produce their own reports live off the main frame. The actual
layout and structure of this mirror MBD is needed ASAP since their MIS needs
it to develop the access routine to interface to said MDB.
