Upgrade to 7.20


We are close to finishing the first pass at upgrading our R/3 6.4 SAP system to 7.20. However the restart of the T03 system has stopped at the MAIN_NEWBAS/STARTSAP_NBAS phase.

This is the error message.

Checks after phase MAIN_NEWBAS/STARTSAP_NBAS were negative!

Last error code set: RFC call to subst_get_uvers failed with key RFC_ERROR_COMMUNICATION (open): SAP_CMINIT3 : rc=20 > Connect to SAP gateway failed Connect_PM GWHOST=CSIAS9, GWSERV=sapgw15, SYSNR=15 LOCATION CPIC (TCP/IP) on local host with Unicode ERROR partner 'CSIAS9:3315' not reached TIME Sat Nov 26 22:12:45 2011 RELEASE 720 COMPONENT NI (network interface) VERSION 40 RC -10 MODULE nixxi.cpp LINE 2898 DETAIL NiPConnect: SYSTEM CALL connect ERRNO 79 ERRNO TEXT Connection refused COUNTER 270 System start failed

When we check the user profile T03OFR there is no kernel library in the library list. The job tried to start the R3_15 subsystem rather then the new SAP15T03 subsystem. We will need to apply a kernel to the T03 system to restart the upgrade.

Any thoughts if we should apply the the OLD kernel C64U0377 or the NEW kernel SAPT03IND
