Hello Michael,
thank you, SAPR3 seems to be correct. The log you sent me is from yesterday, I thought you tried it also today, but never mind.
I am wondering why are you using old SQLDBC client:
C Loading SQLDBC client runtime ...
C SQLDBC Module : E:\sapdb\programs\pgm\libSQLDBC77.dll
C SQLDBC SDK : SQLDBC.H 7.7.7 BUILD 043-123-246-426
C SQLDBC Runtime : libSQLDBC 7.7.7 BUILD 043-123-246-426
if you are running MaxDB vsersion 7.9.08.08. Did you do recent update of DB version?
Perhaps you forgot to update environment/client software?
Check notes 822271 and 649814 if these can be helpful for you.
Also you could give a try to update kernel of shadow instance.
Regards,
Matus
