300MHz Pentium II or
Equivalent (AMD K6-2/Celeron) - 500MHz or better
recommended.
32M-memory minimum, 64-128
recommended depending on advanced features used.
A minimum of hard drive space
is required, as all data files are
server-located. Windows should have at least
100M of space for temporary files and swap file
used, so if this requirement is met, IRis will
be fine.
Operating System: Windows
98/98 SE/ME/NT 4.0+/2000/XP. IRis 3.0 will run
on Windows 95 if system also has Internet
Explorer 5.0+ installed.
Mouse, monitor and keyboard.
Soundcard and speakers are
required for IRis Text-to-Speech (TTS) features.
If TTS is enabled, more memory will be required.
Internet connection and web
browser (Internet Explorer, Netscape Navigator,
Opera, etc.) and E-Mail Client (Outlook, Outlook
Express, etc.) required for certain advanced
features.
Server side:
If IRis 3.0 server installation will also be used
as a workstation, it will need to meet all of the
client requirements as well as having a
recommended amount of hard drive space. (See 'Storage
Requirements' below.)
Other options:
If you are using a file server with an OS other
than Microsoft Windows for an IRis server
installation, you will not be able to use that
server as an IRis workstation. To install to a
non-Windows based server, simply copy the file
images from the provided CD to the file server.
IRis 2.3 requires a minimum of 45 mgs; IRis 3.0
will require a little more. If you're tracking
clients, resources referrals, contacts, services,
volunteers -- basically everything -- you'll need
a minimum of 500 Megs -- it depends on how much
you're tracking and therefore the size of your
database. Basically, the bigger your database, the
more hard drive space you should have -- and as
always, the "bigger is better" rule
applies.
However, you'll also have archiving abilities, or
you can always clean out and remove old data you
don't need anymore if you don't want to upgrade
your hard drive space.
IRis requires 45 megabytes free hard disk space to
install. After installation it will occupy about
30 megabytes. As you add contact/caller records
and agency/service program information you will
need more space. Use the following formula to
calculate the minimum disk space you should have.
These are approximations:
30 Megabytes for basic
installation
3 megabytes hard disk space
for every 1,000 service programs added.
1.5 megabyte for every 1,000
contact (call) records entered.
Additional megabytes for large
reports and lists sent to disk files.
Example:
If your agency maintained 2,000 service programs
and received 50,000 calls per year you would use
approximately this much hard disk space:
2,000
programs
6
megabytes
50,000
calls
75
megabytes
Original
installation
30
megabytes
Reports,
lists, temporary files
10
megabytes
121
megabytes MINIMUM for one year's records
If you imported agency/service
program information from another IRis site you
could easily add an additional 10 to 15 megabytes
of hard disk usage. You should estimate how may
caller records you will take in a year, multiply
that by the number of years of caller's history
you would like to keep. Most sites want at least a
year or two.
IRis can handle approximately 2 million caller
records in one database. For I&Rs that receive
100,000 calls a year that would be 20 years of
history. If you need to go above that you should
"archive" off the older records into a
separate sub-directory.
System Capacities:
IRis comes in both Single-User and Multi-User
versions. Other than the number of concurrent
Users, the features in both versions are the same.
Multi-User IRis allows an unlimited number of
concurrent users. In reality you will find that
this is limited only by the overall speed of the
file server (main computer) and it's ability to
service the workstations. The limits of IRis are
the limits imposed by the language itself.
IRis 3.0 is written using the latest of the
development environment available at design time.
The majority of the program was written in
Microsoft Visual FoxPro 7.0. Other components were
written using components of Microsoft Visual
Studio 6.0.
The physical file limits of IRis are as
follows:
Maximum number of caller
records: 1 Billion records
Maximum number of any single type of record: 1
Billion records
Maximum file size of any single database: 2
Gigabytes (approximately 2 billion characters)
Please note that to
reach the 2-gigabyte file size limit on a single
database you would need to have entered several
million contact/caller records. Since any
referrals, indexes and such are stored as separate
files you would fill a hard disk of approximately
3 to 4 gigabytes. At this point you would probably
want to archive or remove some of the older
records.
