R3trans: Cannot run a nonunicode kernel against a unicode db

One of our SAP system has been upgraded from NON UNICODE (ECC 5.0) to UNICODE (ECC 6.0). The database (Oracle) can be up but the SAP system is failing.

In R3trans execution log, we have found below error,

> R3trans -d

<--oci_execute_stmt(rc=0, iters-errors = 5-0)
con=0, V$NLS_PARAMETERS: NLS_LANG=AMERICAN_AMERICA.UTF8, NLS_NCHAR=UTF8
*** ERROR => Cannot run a nonunicode kernel against a unicode db
(NLS_CHARACTERSET='UTF8')

Solution

Upgrade your kernel version to UNICODE version.
