Issue/Introduction

Dollar Universe lost connectivity with SAP system, even though the SAP server engine was Started and the SAP Target System was up and running.

In universe.log we can see the error messages:

|ERROR|X|SAP|pid=<with some random number>| uxsap_connect_with_retry  | Cannot create connection on SAP system [NodeName/*/]

In dev_rfc.trc file we can see the following errors:

Environment

Release : 6.x

Component : Dollar Universe

Cause

This issue is related to a SAP system limit, for more detail please refer to the SAP note “314530 - Number of RFC/CPIC connections for external clients”

The errors related to CPIC which is a sublayer of the RFC protocol stack. CPIC errors are mainly related to SAP.

Insufficient CPIC conversations set in SAP system can lead to performance problems.

 

Resolution

Create a file unienv_specific in the folder data/nodefiles and define an environment variable to extend SAP conversation limit.

For Linux/Unix, create the file unienv_specific.ksh in which you add a line as following:
export CPIC_MAX_CONV=900

For Windows, create the file unienv_specific.bat in which you add a line as following:
set CPIC_MAX_CONV=900

Restart Dollar Universe to take the change into account.
