With this parameter you can configure the Web-based administration interface.

You must set the parameter, if you want to monitor and administrate the ICM using the browser (see Using the Web Administration Interface). 


To use the ICM administration functions you must have created an initial administration user for yourself in the browser. This procedure is described in Using the Web Administration Interface.

The ICM has opened the port that you set up as the administration port (icm/server_port_<xx>; see below under PORT).


Work area

Character string

Standard value

icm/HTTP/admin_0 = PREFIX=/sap/admin,DOCROOT=$(DIR_ICMAN_ROOT)/admin,AUTHFILE=$(icm/authfile)

Dynamically changeable


Value Range and Syntax

The parameter has the following syntax:

icm/HTTP/admin_<xx> = PREFIX=<URL prefix>, DOCROOT=<directory> [, AUTHFILE=<file name>, PORT=<admin port>, HOST=<admin host>, CLIENTHOST=<admin client>] 

This is explained below.

?     <xx> stands for a number. Numbers ascending from 0 must be used (compare with Generic Profile Parameters with the  Ending _<xx>).

·         PREFIX: URL prefix that is called for this HTTP subhandler. The same procedure is used as with the SAP Web Dispatcher. This is described in Processing Administration Requests.

?     DOCROOT: Root directory of the administration files.

AUTHFILE: File name of the authoring file, where the hash values of the passwords for admin users are stored. Default value: icmauth.txt
If you do not have to authenticate the user (for instance, if the user has already been authenticated in the HTTP_auth handler, see icm/HTTP/auth_<xx>), you can you can specify

PORT: Local TCP/IP port where admin requests are accepted. This port must be specified in the parameter icm/server_port_<xx>. The relevant protocol is used according to whether the port is HTTP or HTTPS.

SAP recommends HTTPS, because otherwise the password of the admin user is transferred unencrypted.

Note that you have to specify a port with PROT=HTTPS if you use HTTPS. You cannot use any port that is configured for End-to-End SSL (PROT=ROUTER).

?     HOST: Local host name or IP address where admin requests are accepted. If "local host" or "" is specified here, only local users can use the Web-based interface. If nothing is specified, admin requests are accepted by all host names.

?     CLIENTHOST: Name or IP address where admin requests are accepted. This can restrict administration to one client host. If nothing is specified, admin requests are accepted by each host.


If the parameter has the value

icm/HTTP/admin_<xx> = PREFIX=sap/icm/admin, DOCROOT=./admin, PORT=8888

and port 8888 is defined as an HTTPS port in

icm/server_port_0 = PROT=HTTPS, PORT=8888, TIMEOUT=15

and the host name is saphost, the ICP files are located in the subdirectory admin in the executable directory. You can administrate the ICM from the browser by entering the URL


in every line.

Log on with the initial user that you created when setting up the Web Administration. See Creating Administration Users
