Area Menu

The area menu is located on the left-hand side of the Web Administration Interface and is divided into subareas.

Core System

The core system contains the runtime environment and infrastructure, and is used by both the Web dispatcher and the Internet Communication Manager (ICM).

(Core System Menu)

This submenu contains the following areas:

Core System (Web Dispatcher and ICM)
Area	Function
Monitor	Overview of existing worker threads More information: Architecture of the Internet Communication Manager (ICM)
Core Thread Status	Overview of the central threads (in contrast to worker threads that process connections).
Active Services	Monitors, starts, and deactivates active services (ports). Changes however are lost when system is restarted. To make permanent changes use profile parameter icm/server_port_<xx>.
Active Connections	Connections currently active.
Trace	Displays, resets, downloads trace file. Sets trace level
Parameters	Displays values of profile parameters in the ICM/Web dispatcher environment.
Host Name Buffer	Displays values of the Host Name Buffer, and resets the buffer.
Release Information	Displays release notes
Statistics	Displays statistics
MPI Status	Displays status of MPI communication buffer.
ICM Security Log	Settings for security log, display of log file More information: icm/security_log

HTTP Handler

This area contains the functions of the HTTP handler that is part of both the ICM and Web dispatcher.

Note Note

You can only make changes in this menu if you access the Web admin interface with a user from group admin. You can ascertain whether you have this administration authorization beneath the area menu (Admin rights granted) or in the user overview (admin handler, see below).

More information: Creating Administration Users (use command line)

End of the note.

(HTTP Handler Menu)

HTTP Module (Web Dispatcher and ICM)
Area	Function
Access Log	Displays parameters and protocol file.
Server Cache	Displays parameterization and cache entries.
Access Handler	Configuration of access restrictions; see icm/HTTP/auth_<xx>.
Admin Handler	Display, create, change, and delete administration and monitoring users for the Web admin interface. You can see where the file is in which the user data is defined. To create and mange users choose Change Users in the context menu (right mouse button).
Modification Handler	You can see where the rules for modifying HTTP requests are defined. Modifications are used, or instance, to manipulate header fields, filter requests, and rewrite URLS. More information: Modification of HTTP Requests

Dispatching Module

The dispatching module is the part of the SAP Web Dispatcher that selects the application server. The server is selected depending on the protocol, configuration, load balancing procedure, and so on.

The Web admin interface of an SAP Web dispatcher still contains the following areas on the left-hand side:

(Dispatching Module Menu)

Dispatching Module
Area	Function
Monitor Application Servers	Displays current application servers in the system, divided into ABAP and Java (tab pages ABAP and JAVA). Instances that provide both appear in both views. The following information is displayed for each instance: Name: Name of the instance With the context menu (right mouse button) you can deactivate and reactivate application servers here also. Inactive servers do not get any requests from the Web dispatcher. You can also sent ping requests (HTTP and HTTPS) to each server. Host name: Name of the host on which the instance is running `HTTP/HTTPS Connections`: HTTP(S) port of the application server, maximum number of HTTP(S) connections that the Web Dispatcher can open to the server, current number of existing connections and maximum number of connections since startup. Requests: Number of requests that the instance has received from the Web Dispatcher. There are the following types of request: Stateful: Stateful requests forwarded to the server that has already processed the request. With stateful requests load distribution only takes place for the first request, and all subsequent requests must be forwarded to the same server. For Group: Requests that are distributed within one logon group. Stateless: Requests that are distributed among all possible instances. Capacity: Capacity of an Application Server. You can overwrite the capacity value by choosing Edit Capacity Values from the context menu. Values that have been overwritten in the context menu are flagged. (Capacity) This fixes the values and they can no longer be changed by the system (neither periodically nor in Reload Web Dispatcher configuration). You can remove the fixed values by choosing Unlock Capacity Values from the context menu. More information: Capacity of an Application Server Load: Load factor, used for selecting the application server with the least utilization. Response Times: Response times in microseconds (last average time (calculated from the last 30 requests) and minimum time (since instance was started up)) Last Ping Time: Last measured `ping` time in microseconds
Monitor Server Groups	Display of the current server groups for ABAP, JEE, display of response times, server accessibility, load factor. With the context menu (right mouse button) you can deactivate and reactivate application servers here also. Inactive servers do not get any requests from the Web dispatcher. You can also sent ping requests (HTTP and HTTPS) to each server. More information: Server Selection and Load Balancing Using the SAP Web Dispatcher
SSL End To End Dispatching	Parameterization and display of the entries in the client IP table. More information: End-to-End SSL
URL Mapping	Display of the URL mapping table More information: Architecture and Functions of the SAP Web Dispatcher
URL Filter	URL filter settings. More information: SAP Web Dispatcher as a URL Filter
Parameters	Display of parameters specific to Web Dispatcher. More information: Parameterization of the SAP Web Dispatcher
Session Dispatching	Details about session dispatching (default setting is deactivated). More information: Determining the Server Group

Note Note

If you have configured the Web Dispatcher for multiple systems, a number of menu entries are listed for each system. For an example of this, refer to SAP Web Dispatcher for Multiple Systems.
