Parameterization of the ICM and the ICM Server Cache 

Use

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

You can display most of these parameters in the ICM Monitor and change some of them dynamically. To do this, on the initial screen choose Transaction SMICM Goto ® Parameters ® Display or Change. On the Change screen you can go directly to the RZ11 parameter documentation for the individual parameters.

You can find an example of the setting of the ICM parameter in the instance profile in Sample Profile for the ICM.

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). For information about the parameters relevant for the ICM and Web dispatcher see Profile Parameters for the ICM and SAP Web Dispatcher.

Features

The parameters can be divided into the following groups:

●      Profile Parameters for ICM and SAP Web Dispatcher. These include the profile parameters for configuring the ICM Server Cache.

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

ICM Parameters

exe/icman

rdisp/start_icman

icm/ccms_monitoring  

HTTP Subhandler Parameters

These parameters are also valid for HTTPS, as the ICM SSL closes and processes the request in same way as with HTTP. The parameters are not valid for SMTP.

The parameters are also valid for the SAP Web Dispatcher, if HTTP or HTTPSis specified as the protocol for icm/server_port_<xx> (option PROT). See also SAP Web Dispatcher and SSL.

icm/HTTP/j2ee_<xx>

icm/HTTP/logging_Client_<xx>

For information about parameters with the ending <xx> see Generic Profile Parameters with the Ending _<xx>.

SSL Configuration (HTTPS)

For information about the ICM configuration for HTTPS see Set Profile Parameters for Using SSL.

Work Process-Resources for ICM Requests

If an ICM is being processed in a work process, you will see an entry of type PLUGIN in the User Overview (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.

See also:

Resources can also be managed for processing of RFC requests. See Configuration of System Resources for Parallel RFC.

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.

Example

In the section Example Profiles for the ICM you can see the possible parameter settings.
