Our
consultants were responsible for all Oracle DBA and Oracle development
work for a GIS project with South Yorkshire Police. The
original system was developed on an Ingres based system,
for another Police force, and we were responsible for
setting up the same system under Oracle and Solaris 2.3,
along with transferring tables, data, triggers etc. from
Ingres to Oracle. We used CA-Openroad for the interface
between the GIS application and the Oracle database, and
then set up a replication site using Oracle Replication
The
Operational
Response System (COMRAD) is used as a front line
response system, and as such all calls, including 999
calls, are passed through and handled by the COMRAD
system. This means that the system is required to be
live 24 hours a day, 365 days a year, with the minimum
of operational down time.
The
system is based on a SUN Sparc solution consisting of
two main server sites and five satellite sites. The
satellite sites being control rooms in other districts.
The configuration that the system is currently based on
is that the two main sites each have one Sparc 1000
server with 4 processors, one Sparc 20 with 2 processors
and two RAID arrays. One site is an update site, where
all terminals requiring the ability to edit data connect
to, the other site being for terminals requiring access
to the COMRAD system for MIS purposes. The Sparc 20
servers at each site are standby servers in the case of
a failure of a Sparc 1000. The two RAID devices at each
site are mirrored to provide maximum fault tolerance. At
each satellite office one of the workstations is
configured with an additional external disk, which acts
as a local GIS server.
