The ICM monitor provides various functions for monitoring the status of the ICM and for detecting any possible errors.

Features

You can find the functions described here in the Goto menu.

Trace Files

Using   Goto   Trace File   or   Goto   Trace Level  , you can display the trace file dev_icm, reset it, or set the trace level (values between 0 and 3 are possible, default is 1). You can also display just the start or the end of the file (the first or last 1000 lines). This is a very useful function for large files. Choose   Goto   Trace File   Display Start or End  .

You can download the trace file on to your local computer, which is very useful for large files or if you want to store a file or send it on later. To do this choose    Goto   Trace File   Save File Locally  .

Security Log

To view the security log, choose   Goto   Trace File   Security Log   Display  . You can also download the security log and general information about it

dev_icmbnd

If you want to view the trace file of the external binding program icmbnd, choose   Goto   Trace File   Display Dev_icmbnd  

Parameters

Choose   Goto   Parameters   to display or change the ICM profile parameters. If you choose Change, you can display the RZ11 documentation for every parameter that is executed by placing the cursor on the parameter name and choosing Documentation.

The value field is ready for input for those parameters that can be changed dynamically.

Caution Caution

Note that with dynamic changes, these are lost the next time the instance is started.

End of the caution.
Statistics

Choose   Goto   Statistics   to activate, deactivate, display, and reset the ICM statistics.

Memory Pipes

Choose   Goto   Memory Pipes   for information on the memory pipes that are used for data exchange between the ICM and the work process.

Host Name Buffer

The mapping of host names to IP addresses or of service names to port numbers is buffered in the SAP system, once they have been read from the file system. If a host name or a service name that should be accessed is changed, the host name buffer must be reset. You can display the buffer contents and reset the buffer. Then the ICM reads the updated data from the file system.

To do this choose   Goto   Host Name Buffer   Display   or Reset.

Services

Choose   Goto   Services   to monitor and administer the services (ports that are used for the ICM connections). This is described in Displaying and Changing Services.

Display Connection

Choose   Goto   Display Connection   to display the TCP/IP connections which the ICM has open with a client (HTTP(S) client (browser), SMTP client). Either the ICM accepted the connection or opened it itself I(as HTTP client).

Release Information

Choose   Goto   Release Info   or choose Release Info to display information about the version of the ICM, the release and the patch level of the SAP kernel.

The first line contains general information on the ICM.

kernel information tells you the release of the SAP kernel. Besides kernel release and compile information, this screen provides the following information:

  • update level specifies with which kernel releases the kernel can run in an SAP system. If different application servers should run in a system with different kernel patch statuses, they must all have the same update level.

  • patch number specifies the last patch level that is relevant for the component ICM.

  • source id (the numbers after the point) indicates the actual kernel patch level.

Below you can find the patch comments on the kernel patches that affect the ICM component, as well as additional detail information.

Note Note

You need this information mainly for notifying SAP of any problems that may occur.

End of the note.
HTTP Server Cache

Here you can find functions for Monitoring and Administrating the ICM Server Cache.

HTTP Log

Choose   Goto   HTTP Log   you can display the following information about logging HTTP requests. The functions are available for HTTP logging for servers as well as for clients.

  • Display entries: Display the entries in the logging file

  • Information: Name of the log file, format of the log file, terms for new log files, maximum log file size, cyclical write (yes/no), current number of characters in the log file and the current number of lines in the file.

  • Write buffer: The logging file entries are buffered and are regularly written to the hard disk. Since you can only see the entries that are already on the hard disk with Display Entries, you can use this function to force the buffer contents to be written to the hard disk.

You can find additional information about HTTP logging in Logging in the ICM.

HTTP Server

By choosing   Goto   HTTP Server   you can display information on the HTTP application server (information about the active AS ABAP or AS Java, URL prefix table) as well as load URL prefixes.

If AS Java is not configured (J2EE Server configured = FALSE), all HTTP requests are passed on to AS ABAP. If AS Java is active, the ICM decides, using the URL prefix table, whether the request is sent to AS ABAP or to AS Java: All URL prefixes in the table are sent to AS ABAP, all others are sent to AS Java. The table is determined from the possible prefixes (HTTP service tree and external aliases) of the Internet Communication Framework.

If no AS Java has been configured, the table is not loaded. You can however enforce this using Load URL Prefixes.
