Hi,
isn't that the number which for example is used in the library cache to quickly
identify in which bucket an object exists depending on the object id. I think
Jonathan Lewis showed it in his Oracle Core book, but not at hand at the moment.

Dear oracle-l'ers,
after running into a classic ORA-600 [17114] and reading the corresponding
MOS Doc ID 47411.1, I stumbled upon the term "magic number":
Quote:
Oracle has detected that the magic number in a memory chunk header has
been overwritten.
I know this term from other contexts (often meaning hash or salt values
and the like), but does anybody here know what this particular magic
number is about?
Cheers,
Uwe
