Specifying the Maximum Server Threads for ICM Requests 

Use

The first entry point for client requests in the instance is ICM. If the request is related to a Java application then ICM forwards this request to some of the running Java server nodes. This communication is done via the SAP optimized protocol Fast Channel Architecture (FCA). There are several threads on the Java server node that process such requests passed by ICM.

The number of server threads is configurable via the FCAServerThreadCount property. However, increasing this number is recommended only when the system has a lot of clients and there is possibility for the Java nodes to handle more simultaneous requests.

Increasing the number of server threads, affects the number of available server threads that may be needed by other services/components.

Procedure

You can use the Config Tool to configure the FCA server threads.

If you want to specifies the maximum server threads for ICM requests, proceed as follows:

...

       1.      Start the Config Tool.

       2.      Choose cluster-data  → template  → instance - <n>  → managers  → HTTP Provider Service.

       3.      From the list of properties, select FCAServerThreadCount.

       4.      Set the required maximum server threads.

       5.      Choose Set to apply the new value.

       6.      Choose  Apply changes to save the changes.

       7.      For the changes to take effect, restart the cluster.
