Hello!
We want to migrate our databases (first only our test db's) vom 11g to 12c. Well, I do an expdp from 11.2.0.4 without any problem, then I try to impdp the dump I got into the new database.
Unfortunately I get thousands of errors, always the same structure, like this:
ORA-02374: Konvertierungsfehler beim Laden von Tabelle "BELVIS2002"."TSD_WNMIN195"
ORA-01722: Ungültige Zahl
ORA-02372: Daten für Zeile: VALUE1 : '-~'
This message appears so often, that impdp crashes.
I do apologize for the german error messages, but I think everyone knows the errors. I found them very often via Google. But never with the problem I have in this case, the '-~'.
To explain it: The table "TSD_WNMIN195" is a very big table, as it contains timeseries-data, so there may be easily millions of lines with each 96 float values (fields VALUE1-VALUE96).
I know, that the main problem is because of negative values. But what exactly does '-~' mean? I couldn't find any informations on the internet.
The only workaround I have so far, is to - before expdp - rewrite all negative values to 0 (=zero), then expdp and impdp works really fine, without any problem. I can do that with our test databases, but not with customer databases, it would destroy very important data.
Can anyone help me with that problem?
Best regards
Yann

These are binary float numbers (single and double) not the same than NUMBER number(!):
SQL> WITH DATA AS(SELECT -1/0F COL FROM DUAL)
2 select dump(col), dump(1/0F), dump(-binary_double_infinity) from data;
DUMP(COL) DUMP(1/0F) DUMP(-BINARY_DOUBLE_INFINITY)
---------------------------- -------------------------- -------------------------------------------
Typ=100 Len=4: 0,127,255,255 Typ=100 Len=4: 255,128,0,0 Typ=101 Len=8: 0,15,255,255,255,255,255,255
Minus infinite (-~) is a NUMBER number (type 2) with internal value a single byte to 0. I don't know if Oracle sees them as equal but it is worth to try it.
(Note the strange thing that happens to the internal representation of 1/0F.)
