there is a weird issue, happening accross the landscape (on Windows Server 2012R2),
but ONLY on 18c databases...
Out of a sudden, sqlplus / as sysdba starts producing ORA-01017 errors !!
It becomes impossible to login to sqlplus and only rebooting the Windows box brings
I have noticed, that the DB was only patched from 18.3 to 18.5, but no SAP bundle
patch has been applied...
Any helpful ideas will be highly appreciated :-) Many thanks !!!
