Oracle Retail Store Inventory Management - Version 14.0.1 and later
Information in this document applies to any platform.


If Store Inventory Management (SIM) version 14.0.1 or 14.1 is installed in a cluster environment, note that the application works fine. However, when the users access the MPS Workers using SIM GUI, then a severe system error occurs with the following message trace:

oracle.retail.sim.common.core.SimServerException: Error occurred during service invocation.
