Here is an example Server Tasks line from Lotus Notes Server's notes.ini :
ServerTasks=Replica,Router,Update,Stats,AMgr,Adminp,Sched,CalConn,Event,HTTP,DIIOP,maps
The file notes.ini is found in the Lotus/Domino/data directory.
You can edit it using notepad or a similar text editor.
Servers these days have some much anti virus and firewall programs running on them, that trying to speed up the Lotus Notes Domino server can be a useful exercise, I decided to remove some redundant tasks. Also removing redundant tasks will speed up starting and stopping the Lotus Notes server.
DIIOP : Sometimes know as just IIOP ( Internet Inter-ORB Protocol) . The D stands for Domino. This is the CORBA (Common Object Request Broker Architecture) mechanism for the Lotus Notes Server. It is needed if you are using Java applets that talk to the server, or your web page connects javascript to the server using livelink and a Java applet.
You can load it by using load diiop. You can stop it using tell diiop exit. You can also refresh security settings by using tell diiop refresh.There are settings in the Server document to define how many threads there are.
I removed this task by removing it from the list of ServerTasks.
Calendar Connector: This task allows the calendars to talk to each other and is not much use if you are not using Lotus Notes calendars.
This task actually responds to tell calconn exit and load calconn.
Sched: The Lotus Notes scheduler task is used to run agents at the right time, and to schedule replication. I doubt if this can be taken out on most servers.
Maps: The Lotus Notes maps extractor is another task that can be removed I reckon as it is used to draw a nice picture of where mail is routed and where replication is done. A decent admin would have a picture of this in their mind anyway. It can always be reinstated if necessary.
The task responds to tell maps exit and load maps.
http: This is the web server task. If you do not use the web on the Lotus Notes server, ie the server is only used for mail routing and/or Lotus Notes Client access, then remove it, otherwise leave it alone.
