Sample Profiles for the ICMLocate this document in the navigation structure

A number of example profiles for SAP NetWeaver Application Server are presented below. It displays only those parts that are relevant for the ICM and the ICM server cache.

A number of example profiles for the SAP NetWeaver Application Server are presented below. It displays only those parts that are relevant for the ICM and the ICM server cache.

You can transfer the following parameter values directly into the instance profile of a SAP NetWeaver.

Application Server with HTTP, HTTPS, and SMTP Access

If you want to configure the for HTTP, HTTPS, and SMTP, add SAP NetWeaver Application Server (for example), the following lines to your instance profile.

Sample Code 
# Definition of the ports
icm/server_port_0 = PROT=HTTP, PORT=1080
icm/server_port_1 = PROT=HTTPS, PORT=1443
icm/server_port_2 = PROT=SMTP, PORT=1025
Note

The following profile parameters are now obsolete:

  • sec/libsapsecu

  • ssf/name

  • ssf/ssfapi_lib

  • ssl/ssl_lib

More information: SAP Note 2198198 Information published on SAP site.

To use the FIPS-140-2-certified cryptographic kernel, set profile parameter ccl/fips/enable.

Application Server with Low Load Expected

If the expected load for the ICM is low, you can keep the number of threads small.

Sample Code 
# Number of threads
icm/min_threads = 10
icm/max_threads = 20

More information:

icm/min_threads

icm/max_threads

Application Server with a High Load Expected

If you anticipate a high load for your SAP NetWeaver Application Server, you can set the following parameters to large values.

# Number of worker threads
icm/min_threads = 50
icm/max_threads = 250

# Increase MPI memory area
mpi/total_size_MB = 400

# Max. number of connections, length of request queue
icm/max_conn = 1000
icm/req_queue_len = 1000
Caution

The high-load recommendations are based on a 64-bit system. These settings could cause memory or address space bottlenecks on 32-bit platforms.

Binding Ports < 1024 on UNIX

If you want to bind ports less than 1024 on UNIX, you can use the external additional program icmbnd.

# Use default ports 
# icmbnd needs root permissions
# "chown root icmbnd" and "chmod 4755 icmbnd
  icm/server_port_0    = PROT=HTTP, PORT=80, EXTBIND=1
  icm/server_port_1    = PROT=HTTPS, PORT=443, EXTBIND=1
  icm/server_port_2    = PROT=SMTP, PORT=25, EXTBIND=1
  exe/icmbnd    = <path of executable>

icm/server_port_<xx>

Activating the HTTP Log File

Working with an HTTP log file is described in Logging in the ICM and Web Dispatcher. In the following example, the file is rewritten every month.

icm/HTTP/logging_0 = PREFIX=/, LOGFILE=access_log, MAXSIZEKB=4000, SWITCHTF=month, FILEWRAP=on
