Maintaining the ICF Profile Parameters (SAP Library - Components of SAP Communication Technology)

Maintaining the ICF Profile Parameters

Use

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:

ICF profile parameters

Parameter	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 begins with the highest maintained parameter, continuing downwards. If, for example, you have maintained the parameters ../virt_host_0 to ../virt_host_5 the analysis 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 to ../virt_host_0.	When carrying out these steps, make sure that there are no "gaps". Otherwise, subsequent parameters will be ignored. If, therefore, parameters ../virt_host_0 to ../virt_host_5 have been maintained, but not ../virt_host_6, then ../virt_host_7 would 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	Meaning
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.

Caution

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).
