MCH3601 QC2POSIX error on V5R1 after applying EPCs to LANSA 11.3 (CU3)

Date:	31 January 2007
Product/Release:	LANSA for iSeries V11.3
Abstract:	QC2POSIX error on V5R1 after applying post CU3 EPCs
Submitted By:	LANSA Technical Support

Description:

The following applies to V5R1 only.

Any EPC post EPC771 (EPC771 is also referred to as CU3) should not be applied to a LANSA 11.3 system if this LANSA system is on OS/400 V5R1. This specifically means you cannot apply EPC790 or higher to LANSA 11.3. By applying post CU3 EPCs to a LANSA 11.3 environment, you may generate a connection error when connecting to V5R1 via the LANSA Listener. The error in the iSeries joblog is:
