Function documentationMaintaining the ICF Profile Parameters Locate this document in the navigation structure

 

You can use the function for maintaining profile parameters (transaction RZ11) to configure various system parameters that directly or indirectly affect how the ICF works.

Integration

In addition to the indirect ICF parameters, there are a number of other parameters that control functions such as layers (ICM, Web Dispatcher), thus influencing the ICF environment.

Prerequisites

Before changing profile parameters, you need to inform yourself about their functions in the relevant documentation in transaction RZ11.

Features

You can use the following parameters to directly control ICF processes:

Parameters

Meaning

Notes

is/HTTP/virt_host_<n>

Parameters is/HTTP/virt_host_0 to is/HTTP_virt_host_9 define the depiction of computers and services used to address an HTTP request on a "virtual host". In turn, the virtual host controls request handler searches (see transaction SICF).

The definition of the virtual host beigns with the highest maintained parameter, continuing downwards. If, for example, you have maintained the parameters ../virt_host_0 to ../virt_host_5analysis will commence with ../virt_host_5 If this parameter corresponds, it will be used to define the request handler. If not, the analysis will continue from ../virt_host_4 ../virt_host_0.

When carrying out these steps, make sure that there are no "gaps". Otherwise, subsequent parameters will be ignored. If

the parameters ../virt_host_0 to ../virt_host_5 have been maintained, but not ../virt_host_6, then ../virt_host_7 will be

ignored.

Parameter is/HTTP/virt_host_0 sets the default host (see transaction SICF).

icf/accept_client_profile_level

Determines whether a client can change the SAP system profiler level

Changing this parameter might be necessary for diagnosis purposes.

However, for security reasons, this is not a standard option.

If you have activated one of these profile parameters, make sure that it is deactivated once the action is completed. This value influences the runtime of the HTTP request

icf/accept_client_recorder_level

Determines whether a client can change the SAP system recorder level

icf/accept_remote_profile_level

This parameter determines whether an external client may change the SAP System profiler level.

icf/accept_remote_recorder_level

Determines whether an external client can change the SAP system recorder level.

icf/option_list

This parameter is for SAP internal use

icf/shared_memory_cache_off

Switches the storage cache on/off

You can use the following parameters to indirectly control ICF processes:

Other relevant profile parameters

Parameter

Bedeutung

icm/*

Parameter for controlling the ICM

wdisp/*

Parameter for controlling the web dispatcher

Activities

To change profile parameters, proceed as follows:

  1. Call transaction RZ11.

  2. Read the documentation for the parameter that you want to change.

  3. Make any necessary changes to the parameter.

  4. Save your changes.

Note that dynamic changes to the parameter are lost next time the system is restarted. If you want to set the parameter permanently, you have to set this in the profile file (instance profile).
