Administration of the Internet Communication Manager

The Internet Communication Manager (ICM) is the component of the NetWeaver Application Server that receives and sends Web requests (HTTP, HTTPS, SMTP).

If you want to use the application server as a Web server or client, you have to configure and monitor the ICM. The ICM administration functions are managed partly using profile parameters, and partly using the ICM monitor (transaction SMICM).

Technical System Landscape

You can find information about the structure and functions of the ICM in the architecture documentation under Internet Communication Manager (ICM).


The most important administration tasks that you need to perform in connection with the ICM are listed below:


Parameterization of the ICM and the ICM Server Cache contains all the profile parameters that are important for operating the ICM. You will also find an example profile here. In a very few cases you may need the CommandLineProgram.


Monitoring the ICM describes how to administrate and monitor the ICM. You can use the ICM Monitor or the Web Administration Interface to do this.

Using operating system signals

You can also control the ICM using operating system signals. For details see Using Signals to Control the ICM.


The ICM enables requests to be recorded. For more information see Logging in the ICM

Using UNIX ports <1024

If you want to bind ports with numbers under 1024 in UNIX, you can use an external binding program. For more information see: Binding Ports < 1024 on UNIX.

Setting up error handling

You can configure HTTP errors to be handled by the ICM. The procedure is described in Error Handling Using the ICM.

Error analysis and correction

For tips on analyzing errors with the ICM see Problem Analysis and Error Search.
