ICM Parameters

Use

This section explains the profile parameters relevant to the operation of the ICM and the ICM server cache.

You can display and change most of these parameters in the Web administration interface or the ICM monitor (AS ABAP): transaction SMICM).

Integration

Most of the parameters are also valid for the SAP Web Dispatcher. Exceptions are parameters that control the SMTP communication, and parameters that control the communication with the backend (work process).

Features

The parameters can be divided into the following groups:

  • Profile parameters valid for the ICM and SAP Web Dispatcher. These include profile parameters for configuring the ICM Server Cache, and all HTTP subhandler parameters (icm/HTTP/*).

  • Profile parameters that apply exclusively to the ICM. There are described below.

ICM Parameters

These parameters control how the ICM is started and the connection to CCMS (Central Computing Monitoring System) in AS ABAP:

  • exe/icman

  • rdisp/start_icman

  • icm/ccms_monitoring

Work Process Resources for ICM Requests

If an ICM is being processed in a work process in AS ABAP, you will see an entry of type PLUGIN in the user overview (transaction SM04). The following profile parameters are available for configuring resources:

  • icm/<PROT>/context_quota

  • rdisp/http_check

  • rdisp/http_min_wait_dia_wp

  • icm/wp_mpi_available

  • icm/wp_roll_timeout

  • icm/cancel_strategy

The settings enable you to determine how many plug-in requests (HTTP, HTTPS, SMTP, etc.) can be processed at the same time in the application server.

System resources are managed in the same way when RFC requests are processed.

Activities

Most of the profile parameters are preconfigured to allow the smooth operation of the ICM and the ICM server cache. Normally, you only have to set a few of the central parameters.
