Re: how to check 32 bit -> 64 bit migration

Your first question was "Does anyone know if a database is currently in 64 or 32 bit?".
The answer is : select
  2 length(addr)*4 || '-bits'
  3 from
  4 v$process
  5 where
  6 ROWNUM =1;
  which gives you that the database is currently in 64 bit.   If you want to find out at what bit rate was the database created, then you have to use the case statement that I gave you.

  After you ran both the queries, what you got as out is correct. That is, the database was first created as 32 bit, but it is currently at 64 bit.

  Now if you want to know whether someone has already run utlrp.sql, there is no query for that. However, you can run the utlrp.sql any number of times. Nothing will happen to the database. If you are unsure of whether anyone has run the utlrp.sql script, you can run it again. No problem.
