I would dig through some details for sys.diana.
I tried yesterday a bit but wasn’t able to make much headway because of lack of
time
What I understand that for 32 bit to 64 bit the plsql word size changes/format
and that’s why utlrp has to be run.
There must be some reference somewhere to what the word size is
Just an idea

as we can see there is no difference so the queries provided gives no useful
info.... any more suggestions?
Thanks

Hi Ram
I have used that query as well, I dont want to know if the database was created
in 32 bit, I want to know if it currently runs in 64 bit mode, that is if
UTLIRP.SQL has been run.
I will test all your sugegstion anyways in a few hours time and let you know
Thanks!

Try this. I used this query long time ago:
/* To identify whether a database was created as 32-bit or 64-bit,
execute the following SQL statement: */
select
case
when INSTR(metadata,'B047') > 1 then 'The Database is 64 Bit.'
when INSTR(metadata,'B023') > 1 then 'The Database is 32 Bit.'
end as Result
from sys.kopm$ ;
/*
If the output references the string 'B023' , then it indicates that the
database was created as 32-bit.
If the output references the string 'B047' then it indicates that the database
was created as 64-bit.

Hi Ram
I already tested that, once a database is migrated to 64 bit and utlirp.sql is
NOT executed that query returns 64 bit too!

Hi
Does anyone know if a database is currently in 64 or 32 bit?
IHAC migrated a few database a couple of weeks ago from Linux x86 to Linux
x86_64 and they unsure if utlirp.sql is run in all of them.
Anyone know how to check if the database is running in 64 bit mode? All I have
found is how to check binary bitness but not the database.
Thanks
