We can use the ICM monitor (transaction SMICM), which provides various functions for monitoring the status and configuration of the ICM and for detecting any possible errors.
We can find the functions described here in the Goto menu.
Trace Files
Using Goto -- Trace File or Goto -- Trace Level, We can display the trace file dev_icm, reset it, or set the trace level (values between 0 and 3 are possible, default is 1). We 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 Display End.
We can download the trace file on to Wer local computer, which is very useful for large files or if We want to store a file or reuse it 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. We can also download the security log and display general information about it.
dev_icmbnd
If We want to view the trace file of the external binding program icmbnd, choose Goto -->Trace File--> Display--> Dev_icmbnd
Parameter
To display or change ICM profile parameters, choose Goto -->Parameters. If We choose Change, for each listed parameter We can display the RZ11 documentation, by placing the cursor on the parameter name, and choosing Documentation Documentation.
The value field is ready for input for those parameters that can be changed dynamically.
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. We 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).
Release Information
Choose Goto > Release notes 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 We 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.
