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.
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 more information see Parameterization of the SAP Web Dispatcher
For information about parameters with the ending <xx> see Generic Profile Parameters with the Ending _<xx>.
The parameters can be divided into the following groups:
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.
These parameters are used internally for optimizing the I/O throughput (network/MPI).
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:
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.
Resources can also be managed for processing of RFC requests. See Configuration of System Resources for Parallel RFC.
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.
In the section Example Profiles for the ICM you can see the possible parameter settings.
