Deploying IMtegrityBefore you install IMtegrity, you should have an understanding of the various components and the design and configuration decisions you will need to make. This document helps you plan for and deploy IMtegrity. IMtegrity 3.x consists of 2 major components:
IMtegrity Chat Logging Service for IBM Lotus Sametime
The Sametime chat logging module is implemented via the native Sametime SPI (Service Provider Interface) and is installed as the "stchatlog.dll" file in your Sametime server's program directory. The IMtegrity installer automatically deploys this file and configures the Sametime server to correctly use it. To effectively log all IBM Lotus Sametime chats, you need to
install IMtegrity on every Sametime server in your
organization, otherwise only chats from users which are connected to a Sametime
server running the IMtegrity software will be logged.
Note: You need to purchase a separate IMtegrity
licence for every Sametime server you plan on installing the IMtegrity software
on.
IMtegrity Proxy Server service for AOL AIM
The IMtegrity Proxy Server is implemented as a native
Windows service, acting as a proxy between all AOL AIM clients and
the public AOL IM network. The IMtegrity installer automatically registers,
configures and starts the IMtegrity Proxy Server service with default
values.
Note: If you want to log native Sametime chat messages only, you
can stop and remove the IMtegrity Proxy Server
service (either directly using the Windows Control panel or via the
IMtegrity Configuration tool's "Service" tab). However, the service
only consumes very little system resources (~8MB of memory and virtually no CPU
cycles) when in idle mode.
Since the IMtegrity proxy server needs to establish a TCPIP
connection to the internet for AOL AIM connections, you need to pay
special attention to firewall and proxy server
configurations.
If you have multiple Sametime servers but don't expect a lot of
users to use the AOL AIM clients, you might want to run the IMtegrity Proxy
Server on just one single Sametime server, and stop and remove the IMtegrity
Proxy Server NT service on all other Sametime servers, or you might want to run
it on every Sametime server for load distribution and performance reasons.
If you have lots of AOL AIM users, it is recommended
to assign different servers running the IMtegrity Proxy Server to
different groups of AOL AIM users.
AOL AIM Rate Limits per single IP address
The public AOL AIM servers impose a standard rate
limitation that restrict the number of simultaneous AIM sessions that a given
IP address can establish. When your internal users connect to the AIM service
through the IMtegrity Proxy Server, the AOL AIM service will treat these
connections as originating from the same IP address. It is not known what
maximum rate number of simultaneous sessions is.
Note: If your users previously accessed the public AOL IM network
from behind your firewall and not reached/exceeded the rate limit in the past,
it is unlikely that they will hit the limit because of IMtegrity. All sessions
will appear to come from your company's firewall, regardless whether the
IMtegrity Proxy Server runs behind that firewall or not. The IMtegrity proxy
server itself is entirely transparent to the AOL servers.
