Hi,
with select * from v$sgastat I'm getting

Does anybody know where the large_pool free mem number comes from?
Of course I do not have 1,8E+10 GByte of System Memory! Is there any
know problem with Oracle 9?
Additionally I get the error
ORA-04031: 32512 Bytes des gemeinsamen Speichers konnten nicht zugewiesen werden ("large pool","unknown object","cursor work he","x$ktfbfe-bit")
with question to the data dictionary (TOAD->DBA->Tablespaces)
I think this is related but I have no further idea and would appreciate any hint!

Thanks,
Christoph
