Stability Problems with SAP Instances

You are experiencing stability problems with SAP instances where many SAP Agents (RFC connections) are used on one server? The external RFC/CPIC server cannot open more connections, and you must find a solution. See how you can resolve these problems.

The SAP Agent log shows errors such as the following:

20200204/043157.954 - LOCATION CPIC (TCP/IP) on local host with Unicode

20200204/043157.954 - ERROR max no of 202 conversations exceeded

20200204/043157.954 - TIME Sun Feb 4 04:31:57 2020

20200204/043157.954 - RELEASE 721

Solution

The reason for this error is that the setting for the number of parallel connections that can be kept in the library is not high enough.

Start the application, which is the SAP Agent in this case, with the following parameter:

-Djco.cpic_maxconv=500

Example

/usr/bin/java -jar -Xms1024M -Djco.cpic_maxconv=500 /app/uc4/agents_v12/sap/bin/ucxjr3x.jar
